A heating control device for controlling a food processor is disclosed. During a heating process of the food processor, a temperature in a cup of the food processor is obtained at a predefined time interval. Whenever the obtained temperature in the cup reaches a current preset temperature threshold, the food processor starts a stirring operation for a first preset time period and stops after that, until the obtained temperature in the cup is greater than an upper limit of the preset temperature threshold. The preset temperature threshold is adjusted and defined as the current preset temperature threshold every time before the food processor starts the stirring operation. The heating control device for controlling the food processor solves a problem of a low accuracy in heating control that is caused by an unbalanced temperature in the cup of the food processor during the heating process.

An exhaust system is provided that includes at least one exhaust aftertreatment unit provided in an exhaust fluid flow pathway and a thermal storage device disposed upstream from the exhaust aftertreatment unit. The thermal storage device is operable to store thermal mass and provide thermal insulation to enable a catalyst to maintain a minimum predetermined temperature for a minimum predetermined time. In one form, a heater is also provided proximate the thermal storage device, along with variations that include a secondary flow pathway for the thermal storage device.
摘要:
A system and approach for developing a periodic water usage profile and demand for controlling a water heater. A mode may be selected for demand for a certain amount of water of a particular temperature range to be available for use from the water heater. Data on hot water usage may be collected and the usage profile and demand may be calculated from the data. The water heater may be programmed to operate in a certain fashion based on the usage profile and demand. A control knob may be on the water heater control to select a particular demand. Control of the water heater may be operated from a remote device connected in a wireless or wired fashion. An optimization program may be implemented in the control of the water heater for achieving one or more beneficial goals related to water heater performance and hot water production.

A fluid flow control device controls flow of coolant in a motor vehicle motor cooling system. The flow control device includes first and second coolant inlets and first and second coolant outlets. The flow control device is operable selectively to direct coolant flowing into the device to flow out from the flow device through one or both of the first and second outlets in dependence on a temperature of fluid flowing through the device.

A conversion unit for an air conditioning system to cause it to act like the cooling unit of a refrigeration system comprises a frost detector, an A/C temperature control defeating mechanism and a control unit which operate together to force the range of operation of the air conditioning unit into the range of operation of a refrigeration unit. The conversion unit is particularly useful for providing low cost cooling systems for farmers in third world countries for keeping their produce fresh and safe, not to mention its use by all farmers around the world and by florists or others in need or desire of an economical refrigeration alternative. The present invention is also usable to provide inexpensive cooling to RV's and to refrigerated vehicles.
摘要:
An electronically controlled thermostat is obtained enabling stable valve body actuation, preventing overshooting and hunting, and with a reduced overall device size and simplified construction. An electronically controlled thermostat 1 capable of arbitrary variable control of cooling water temperature comprises a thermo-element 4 having a piston which actuates the opening and closing within a housing of a first valve body 11 and a second valve body 18 to perform switching of the flow path of cooling water by sensing the cooling water temperature, and an element guide member 25 which holds the thermo-element within the above housing 10. A temperature-sensing chamber is provided, formed by isolation by the element guide member from the flow path in which cooling water on the radiator exit side flows; the temperature-sensing portion of the element 4 is disposed so as to face this nullchambernullvii. A linking hole 25a is provided as a heat transmission means to transmit the temperature of cooling water on the radiator exit side from within the flow path to the element temperature-sensing portion within the temperature-sensing chamber.
