The temperature controller is installed in the storing chamber. A heater installed in the storing chamber and bimetal part installed out of the storing chamber are used to regulate the temperature in the storing chamber according to the temperature outside, so that temperature in the storing is regulated suitably.
Description
Technical field
The present invention relates to the refrigerator field.
Background technology
Usually, refrigerator inside is divided into refrigerating chamber and refrigerating chamber.Refrigerating chamber is used for ice making or food is kept at below the uniform temperature.Refrigerating chamber stores the refrigeration thing.Refrigerator inside is provided with the refrigeration system device, and refrigeration system circulation is evaporated, compression, condensing, the refrigeration operation of expanding.This system utilizes the evaporimeter heat absorption in the closed circuit, carries out freezingly, and refrigerator is maintained freezing, frozen state.
Fig. 1 is a conventional refrigerator internal structure front elevation.Fig. 2 is the refrigerator internal structure side cut away view among Fig. 1.At first, as shown in Figure 1 and Figure 2, refrigerator comprises casing 1, refrigerating chamber 10, refrigerating chamber 20, refrigerating chamber door 11, refrigerating-chamber door 21, temperature measuring equipment 23, laminate 22.Wherein, the casing 1 inner refrigerating chamber 20 that is divided into the refrigerating chamber 10 and the refrigeration of freezing and storage food by division board 15 and stores food with casing 1 formation one.Refrigerating chamber door 11 and refrigerating-chamber door 21 are located at the front of casing 1, open and close refrigerating chamber 10 and refrigerating chamber 20 respectively.Temperature measuring equipment 23 is located in the case, detects the temperature of refrigerating chamber 20.Several laminates 22 are located in the refrigerating chamber 20, refrigerating chamber 20 are divided into the several sheaf spaces that can place food.
Cooling air circulation system is formed on refrigeration system 30, blowing fan 12, pipeline 13, switch 14, circulating cold air road 16.Refrigeration system 30 produces the required cold air of refrigerating chambers 20 and refrigerating chamber 10.Blowing fan 12 is located at the rear of casing 1, and the cold air that refrigeration system 30 produces is blown to refrigerating chamber 10.Pipeline 13 is formed in the casing 1, in the cold air guiding refrigerating chamber 20 of refrigeration system 30 generations.Switch 14 is located in the pipeline 13 of casing 1, opens and closes pipeline 13 with being allowed a choice.Circulating cold air road 16 is formed on casing 1 and forms in the dividing wall 15 of one, and the air after the refrigerated compartment 20, water conservancy diversion is cooled it in refrigeration system 30 again.
As shown in Figure 3, refrigeration system 30 is made up of the compressor 31 that is located at lower end, casing 1 rear, condenser 32, capillary 33 and the evaporimeter 34 that is located at casing 1 refrigerating chamber 10 rears.Compressor 31 is compressed into the gas coolant of low temperature, low pressure the liquid refrigerants of high temperature, high pressure.Condenser 32 is transformed into the liquid refrigerants of high temperature, high pressure the liquid refrigerants of low temperature, high pressure.Capillary 33 is transformed into the liquid refrigerants of low temperature, high pressure the liquid refrigerants of low temperature, low pressure.Evaporimeter 34 allows the liquid refrigerants of low temperature, low pressure evaporate, and becomes the gaseous coolant of low temperature, low pressure.
As above the conventional refrigerator of Gou Chenging for the food of placing on each laminate 22 in long-time storing frozen chamber 10 or the refrigerating chamber 20, after the energising, is accepted the control signal of controller, and compressor 31 is compressed into the gaseous coolant of low-temp low-pressure the gaseous coolant of HTHP.And the gaseous coolant of this HTHP is condensed into the liquid refrigerants of cryogenic high pressure when the condenser 32.
When being passed through capillary 33, become the liquid refrigerants of low-temp low-pressure by condensing cryogenic high pressure liquid refrigerants.And the liquid refrigerants of this low-temp low-pressure flashes to the gaseous coolant of low-temp low-pressure when the evaporimeter 34.At this moment, under the evaporation of evaporimeter 34, ambient air carries out being cooled after the heat exchange, produces cold air.
The cold air of Chan Shenging like this, a part is under the effect of casing rear blowing fan 12, be sent in the refrigerating chamber 10, refrigerating chamber 10 is cooled to uniform temperature, food is frozen, and another part enters in the refrigerating chamber 20 by being formed on the pipeline 13 in the casing 1, refrigerating chamber 20 is cooled to uniform temperature, food is refrigerated.
Temperature measuring equipment 23 detects the temperature of refrigerating chamber 20, and testing result is delivered in the controller (figure slightly).If temperature arrives uniform temperature, controller will send signal to compressor 31, and compressor 31 is quit work, and regulates the circulation of cold air with this.
When allowing cold air enter refrigerating chamber 10 and refrigeration in 20, refrigerating chamber 10 and refrigerating chamber 20 coolings.Then, under the working on of refrigeration system 30, the cold air of refrigerating chamber 20, by being formed on the circulating cold air road 16 of the refrigerating chamber 10 on casing 1 separates walls 15, water conservancy diversion is in evaporimeter 34.Like this, under the effect of evaporimeter, continue to produce cold air.
But there are the following problems to possess the conventional refrigerator of said structure.The cold air that evaporimeter 34 produces is assigned in refrigerating chamber 10 and the refrigerating chamber 20 by the ratio that configures in advance.Therefore, around under the variation of temperature, when the variations in temperature of refrigerating chamber 10 and refrigerating chamber 20 was big, promptly environment temperature was being taken the photograph formula 5 degree for a long time to 15 degree when following, and the running rate of compressor 31 can significantly descend, and makes the temperature rising of refrigerating chamber 10.
Summary of the invention
Technical problem to be solved by this invention is, a kind of refrigerator attemperating unit is provided, and adopts bimetal release that is exposed on the external and the electric hot plate that is attached thereto, and makes the suitable state of temperature maintenance in the case, improves the cooling effectiveness of refrigerator.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: refrigerator is divided freezing by dividing wall and is stored the refrigerating chamber and the refrigeration of food and store the food cold storage chamber; Cooling device is installed in the electric refrigerator housing body, produces refrigerating chamber and the required cold air of refrigerating chamber; Temperature measuring equipment is located at the inside of refrigerating chamber, detects internal temperature, the control cooling device; In comprising the attemperating unit that casing and temperature measuring equipment are formed, also comprise electric hot plate and bimetal release; Electric hot plate is located at the inside of refrigerating chamber, produces certain heat; Bimetal release is located at the outside of casing, presses the work of external temperature control electric hot plate.
The invention has the beneficial effects as follows: the refrigerator attemperating unit is when environment temperature arrival uniform temperature is following, and the bimetal release that is located at top, the casing outside is connected, and makes the electric hot plate energising that is located at refrigerating chamber inside, the generation heat.The heat that distributes can make the internal temperature of refrigerating chamber rise, and temperature measuring equipment detects the temperature after this rising, and compressor is suitably turned round.Can supply cooling required cold air sufficiently, improve cooling effectiveness.
