Technical Field

[0002] A freezer, also known as a freezer, is a device that preserves food and other items at low temperatures. It is divided into household and commercial types. The basic function of a freezer is to refrigerate and keep the inside of the box at an appropriately low temperature. The refrigeration system is generally composed of four basic components: a compressor, a condenser, a capillary tube, and an evaporator. The refrigerant is a liquid that can boil at low temperature under low pressure and absorbs heat when boiling. The refrigerant circulates continuously in the refrigeration system. The compressor increases the gas pressure of the refrigerant, creating liquefaction conditions. When passing through the condenser, it condenses and liquefies to release heat, then reduces the pressure and temperature when passing through the capillary tube, and then boils and vaporizes when passing through the evaporator to absorb heat to achieve a refrigeration effect.
[0003] In order to classify the stored food, a general refrigerator is provided with a refrigerating chamber main body and a freezing chamber main body. The existing refrigerator can generally only control the temperature of the freezing chamber main body, and the refrigerating chamber main body does not participate in the control. The temperature control of the refrigerating chamber main body is not accurate, and it is easy to be overcooled and iced. It is easy to have a phenomenon of being overcooled on one side and hot on the other side. The temperature control is not accurate and the consistency is poor. Therefore, a dual-temperature cabinet control system with switchable display control for refrigeration and freezing is needed. Utility Model Content

[0021] Insert blocks 23 are respectively provided at both ends of both sides of the second partition 22, and insertion holes 24 matching the insertion blocks 23 are evenly opened on the first partition 21. By inserting the insertion blocks 23 on the second partition 22 into different insertion holes 24 on the first partition 21, the size of the storage space can be adjusted to meet different storage needs; one side of the top of the refrigerator body 10 and the freezer body 4 is respectively connected with the second cover body 18 and the first cover body 19 through hinge rotation, and the bottom sides of the first cover body 19 and the second cover body 18 are provided with sealing gaskets 20 to improve the airtightness of the refrigerator body 1.
[0022] A first evaporator 6 and a second evaporator 8 are respectively arranged in the side walls inside the freezer compartment body 4 and the refrigerator compartment body 10; a first chamber 5 is arranged on one side inside the refrigerator compartment body 1, and a compressor 3 is arranged inside the first chamber 5; a second chamber 11 is arranged at the bottom end of the refrigerator compartment body 1, and a condenser 12 is arranged inside the second chamber 11, one end of the condenser 12 is connected to the compressor 3, and two solenoid valves 13 are arranged at the other end of the condenser 12, and the upper ends of the two-way solenoid valves 13 are respectively connected to the first evaporator 6 and the second evaporator 8 through a first capillary 14 and a second capillary 15, and a controller 26 is arranged at a central position on one side of the refrigerator compartment body 1.
[0023] The compressor 3 increases the gas pressure of the refrigerant to create liquefaction conditions. The refrigerant condenses and liquefies to release heat when passing through the condenser 12, and then reduces the pressure and temperature through the first capillary tube 14 and the second capillary tube 15, and then boils and vaporizes through the first evaporator 6 and the second evaporator 8 to absorb heat to achieve a refrigeration effect.
[0024] Heat dissipation fins 16 are evenly arranged on one side of the condenser 12, and the heat dissipation fins 16 are made of copper alloy. Heat dissipation holes 25 are evenly opened on one side of the bottom of the refrigerator body 1 to ensure ventilation and heat dissipation of the refrigerator body 1; the first temperature sensor 7 and the second temperature sensor 9 are respectively arranged inside the freezer compartment body 4 and the refrigerator compartment body 10.
[0025] The output ends of the first temperature sensor 7 and the second temperature sensor 9 are electrically connected to the input end of the controller 26 through wires, and the output end of the controller 26 is electrically connected to the input ends of the compressor 3, the two-way solenoid valve 13 and the heating wire 17 through wires.
[0026] The first temperature sensor 7 and the second temperature sensor 9 respectively sense the temperatures in the freezer compartment body 4 and the refrigerator compartment body 10, and the two-way solenoid valve 13 controls the distribution of circulating refrigerant flowing to the refrigerator compartment body 10 or the freezer compartment body 4 according to different requirements for cooling capacity for refrigeration or freezing.
[0027] The temperatures of the freezer compartment body 4 and the refrigerator compartment body 10 can be independently controlled by the controller 26. The refrigeration processes of the refrigerator compartment body 10 and the freezer compartment body 4 are independent of each other, so the temperatures of the two compartments do not affect each other, thereby ensuring that the temperatures of the two compartments are relatively stable.

[0029] A muffler 2 is connected between the compressor 3 and the condenser 12, and the interior of the muffler 2 is a porous structure; the noise of the airflow discharged from the compressor 3 is attenuated after passing through the porous structure in the muffler 2, thereby reducing the noise generated when the refrigerator body 1 is in operation; the specific models and specifications of the muffler 2, the first temperature sensor 7, the second temperature sensor 9, the two-way solenoid valve 13, the heating wire 17 and the controller 26 need to be determined by selection calculation based on the specification parameters of the device, and the selection calculation method is a prior art, so it will not be described in detail.
[0030] The specific working process and principle of the device are as follows: the foods are placed in the freezing chamber body 4 and the refrigerator chamber body 10 respectively; the first partition 21 and the second partition 22 in the freezing chamber body 4 separate a number of storage spaces so that the foods are separated from each other when placed and are not easily stuck together; at the same time, the size of the storage space can be adjusted by inserting the plug 23 on the second partition 22 into different plug holes 24 on the first partition 21; the compressor 3 increases the gas pressure of the refrigerant to create liquefaction conditions; the refrigerant condenses and liquefies to release heat when passing through the condenser 12; then the pressure and temperature are reduced through the first capillary 14 and the second capillary 15; and then the first evaporator 6 and the second evaporator 8 boil and vaporize to absorb heat to achieve a refrigeration effect.
[0031] The first temperature sensor 7 and the second temperature sensor 9 sense the temperatures in the freezer compartment body 4 and the refrigerator compartment body 10 respectively. According to the different requirements of refrigeration or freezing for refrigeration capacity, the two-way solenoid valve 13 is used to control the distribution of circulating refrigerant flowing to the refrigerator compartment body 10 or the freezer compartment body 4. The temperatures of the freezer compartment body 4 and the refrigerator compartment body 10 can be independently controlled by the controller 26 respectively. The refrigeration processes of the refrigerator compartment body 10 and the freezer compartment body 4 are independent of each other, so the temperatures of the two chambers do not affect each other, thereby ensuring that the temperatures of the two chambers are relatively stable. Also, since the refrigeration of the two chambers is relatively independent, different temperature adjustments can be made or the refrigeration operation can be stopped respectively, and the display and control can be switched at will.
