摘要:
A cooking apparatus that is capable of effectively cooling a heat reflecting unit without increasing a temperature thereof, thereby preventing oil dropped onto the heat reflecting unit from being burnt. The cooking apparatus includes a grill unit disposed on a body of the cooking apparatus, a plurality of heating units mounted at sides of an interior of the body while being inclined toward the grill unit, and a heat reflecting unit disposed under the grill unit in the body. The heat reflecting unit includes a pair of partitions disposed in the longitudinal direction thereof while being opposite to the heating units, respectively, such that an interior of the heat reflecting unit is partitioned into a pair of side channels and a central channel by the partitions. The cooking apparatus further comprises cooling fans mounted in front of the side channels, respectively, to cool the heat reflecting unit.

A printing plate and method for fabricating the same is disclosed. A metal layer is first formed on a glass substrate. The metal layer is then patterned in a predetermined shape. The glass substrate is next etched to a predetermined depth using the patterned metal layer as a mask and the metal layer removed. If necessary, additional metal layers have the same or different patterns may be formed on the glass substrate and the glass substrate etched after each metal layer is formed thereon until a desired etching depth in the glass is achieved.

A cooking apparatus includes a body provided in a top thereof with an opening, at least one heating unit arranged on both sides of the body, a grill unit mounted on a top of the body, and a heat reflecting unit arranged toward the heating units below the opening of the body. The grill unit includes a plurality of grill pipes that are filled with water, arranged to be regularly spaced apart from each other and configured to form the effective grill portion. The heating unit includes a pair of heating units arranged on both sides of the body toward the opening of the body. The heating unit is arranged to be inclined at an angle ranging from 30° to 90° (preferably, about 70°) with respect to the effective grill portion of the grill unit. The heating unit is a ceramic heater.

A magnetron includes a positive polar cylinder, a plurality of vanes, a filament, upper and lower shields, and upper and lower pole pieces. The vanes are disposed in the positive polar cylinder to constitute a positive polar section. The filament is disposed on an axis of the positive polar cylinder to define an activating space. The upper and lower shields cover a top and bottom of the filament, respectively. The upper and lower pole pieces are disposed to induce magnetic flux into the activating space. The upper shield preferably has a diameter ranging from 6.95 mm to 7.10 mm. Additionally, the lower shield preferably has a diameter ranging from 6.95 mm to 7.10 mm.
摘要:
A control system for controlling operations of a plurality of electric appliances in distributed arrangements. Each of a plurality of controllers is connected between the power line and respective electric appliance. A remote controller is used to provide a control message to at least one of the controllers. The controller receiving the control message from the remote controller controls the corresponding appliance according to the control message when the control message is directed thereto. When the control message is directed to another controller, the controller which receives the control message provides the control message to the other controllers via the power line. When a data collision happens in the power line, the controller which transmitted the control message to other controllers retransmits the control message after a delay time determined based on a random number.

A microwave oven comprises a magnetron having an anode, a cathode and a filament, and a high voltage transformer having a primary coil and a secondary coil for supplying a high voltage to the magnetron. The microwave oven further comprises a capacitor connected in parallel to the secondary coil of the high voltage transformer, forming a resonance circuit with the secondary coil. With this configuration, the performance of the magnetron is maintained by lowering the anode peak voltage applied thereto during the early non-oscillating period, and the circuit elements are protected from damage by removing the surge voltage.

A food amount detector for automatically detecting the amount of a food placed in a cooking chamber of a microwave oven, a microwave oven employing the food amount detector, and control method thereof. Output voltage of a microwave generator is detected while the microwave oven is driven, and the amount of the food placed in the cooking chamber of the microwave oven is determined based on the output voltage such detected. In accordance with the amount of the food such determined, the food is cooked under the appropriate driving conditions of the microwave oven. Accordingly, the user does not need to determine the amount of the food by himself, or set the driving conditions of the microwave oven such as cooking time, level of microwave energy, etc. As a result, the user finds it convenient when using this microwave oven, and the food is cooked under the exact driving conditions set by the microwave oven. Further, since the price of the parts are inexpensive, the manufacturing cost is reduced, and manufacturing process is simplified, so that productivity is improved.

The present invention relates to a device for rapidly extinguishing a fixed-wick oil stove by closing off an oil-supply tube when the oil stove is overturned or an earthquake occurs. More specifically, it relates to a device of this type which is formed using just a construction having no need for an electrical power source, which reduces costs, which entails no risk of breakdown, and which after the oil stove has been extinguished can straightforwardly be restored to the state prior to operation. The present invention is a fixed-wick oil burner which comprises: a hexahedral housing (40) provided on a support (10); a lever (50) which is supported in such a way as to be able to perform a seesaw movement on a floor plate (41b) of the housing (40), and which is provided with a resilient support member (53) between its under-surface at one end and the floor plate (41b), and which also has positioned, between its other end and the floor plate (41b), an oil-supply tube (22) formed of a heat-resistant flexible material; a weighting member (60) which is provided between an upper plate (41a) and one end of the lever (50) in such a way that a resilient member (61) is used to force face-to-face contact between facing parts, an upper weighting body (62a) and a lower weighting body (62b), and in such a way that the upper end of the upper weighting body (62a) and the lower end of the lower weighting body (62b) come into face-to-face contact with the upper plate (41a) and one end of the lever (50), and which is arranged in such a way that it gives way when a shock force of more than a certain value is transmitted to one or other of the upper and lower weighting bodies (62a) or (62b); and a restoring rod (70) which is connected to the lever (50), with a free end projecting outside the upper plate (41a).
