[0052] The refrigeration device in the present application generally comprises a box body, a door body and a refrigeration system, wherein at least a refrigeration compartment is formed in the box body, and the refrigeration compartment is opened and closed through the door body to meet the requirements of storing and retrieving articles.

[0053] The refrigeration system uses a compressor, condenser, expansion valve and evaporator to perform the refrigeration cycle of the refrigeration equipment. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation to achieve cooling of the items in the box.

[0054] The low-temperature and low-pressure refrigerant enters the compressor, which compresses it into high-temperature and high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0055] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature and low-pressure refrigerant gas to the compressor. The evaporator can cool the items in the box by utilizing the latent heat of evaporation of the refrigerant.

[0056] refer to Figure 1-Figure 3 , Figure 8 The present application proposes a refrigeration device, specifically a refrigerator, which includes a box body 100 and a door body 200. The box body 100 includes a box body shell 110 and a box body liner 120. A refrigeration cavity 101 with an opening facing upward is formed in the box body liner 120.

[0057] The opening of the refrigeration inner cavity 101 serves as an introduction port for placing objects to be refrigerated into the refrigeration inner cavity 101 or taking objects to be refrigerated out of the refrigeration inner cavity 101 .

[0058] An equipment inner cavity 102 is also formed between the box shell 110 and the box inner liner 120 for installing components related to the refrigeration system.

[0059] The equipment inner cavity 102 is located directly below the refrigeration inner cavity 101 .

[0060] refer to Figure 4-Figure 6 The refrigeration system includes a compressor 500, a condenser 600 and an evaporator 400, and the compressor 500, the condenser 600 and the evaporator 400 are connected through a refrigeration pipeline.

[0061] The compressor 500 and the condenser 600 are installed in the equipment inner cavity 102 , and the evaporator 400 is attached to the outer wall of the box body 120 away from the refrigeration inner cavity 101 .

[0062] A fan component 700 is also provided in the inner cavity of the equipment cavity, and the fan component 700 is installed on one side of the condenser 600 .

[0063] The low temperature generated by the evaporator 400 during operation is transferred to the refrigeration cavity 101 through the cabinet liner 120 to cool the refrigeration cavity 101 or the refrigeration medium in the refrigeration cavity 101 .

[0064] The material of the box inner liner 120 is stainless steel, and the box inner liner 120 contains refrigerant. The cold energy generated by the evaporator 400 is transferred to the refrigerant to cool the components to be frozen in the refrigerant.

[0065] The refrigeration method of the freezing liquid is not air conditioning, but cooling liquid. It can be in direct contact with the frozen food for naked freezing or the frozen food can be vacuum-packed and then quickly frozen, which improves the efficiency of the freezing operation and is non-toxic and harmless to food.

[0066] In other words, the freezing liquid utilizes the efficient thermal conductivity of the liquid. The method of freezing the liquid is very simple. You only need to seal the food and then put it into the freezing liquid. The freezing speed is several times faster than the conventional air conditioning freezing method.

[0067] The low-temperature airflow formed by the evaporator 400 is transferred to the freezing liquid through the box body 120 to keep the freezing liquid at a low temperature. Seafood, meat and other foods that need to be frozen are directly put into the freezing liquid after sealing. The freezing liquid soaks the food, and the food is fully in contact with the low-temperature freezing liquid. The low temperature of the freezing liquid can freeze the food faster, so that seafood, meat and other foods can be quickly frozen, reducing the formation of ice crystals in meat cells, and maintaining the nutrition and taste of seafood, meat, etc.

[0068] Reference again Figure 4-Figure 6 The output end of the compressor 500 is directly connected to the condenser 600, and the output end of the condenser 600 is connected to the de-condensation pipe 910. The de-condensation pipe 910 is installed at the opening position of the box 100. The heat dissipated by the de-condensation pipe 910 is used to reduce the temperature difference between the box 100 and the external environment to reduce and eliminate condensation.

[0069] A filter is connected downstream of the dew removal pipe 910. The filter is used to filter impurities and pollutants in the refrigerant, and to absorb and remove moisture in the refrigerant to reduce malfunctions.

[0070] The evaporator 400 is connected downstream of the filter, and includes a first evaporator 410 and a second evaporator 420 .

[0071] The first evaporator 410 is connected to the output end of the condenser 600 through a first refrigerant branch, and the second evaporator 420 is connected in parallel with the first evaporator 410 through a second refrigerant branch.

[0072] That is, both ends of the first refrigerant branch and the second refrigerant branch are respectively connected to the refrigerant pipeline 900, and the first refrigerant branch and the second refrigerant branch are arranged in parallel.

[0073] A first capillary tube 411 is disposed on the first refrigerant branch, and a second capillary tube 421 is disposed on the second refrigerant branch. The first capillary tube 411 is located upstream of the first evaporator 410 , and the second capillary tube 421 is located upstream of the second evaporator 420 .

[0074] As a throttle valve in the refrigeration system, the capillary tube is an important piping component in the refrigeration system. Its main function is to control the flow and pressure of the refrigerant through capillary action and realize the transition of the refrigerant between the high-pressure area and the low-pressure area.

[0075] The first refrigerant branch and / or the second refrigerant branch are also provided with a switch component for controlling the on and off of the first refrigerant branch and / or the second refrigerant branch.

[0076] Specifically, a first switch element 412 is provided on the first refrigerant branch for controlling the on / off of the first refrigerant branch, and further controlling the on / off of the first evaporator 410 .

[0077] The second refrigerant branch is provided with a second switch element 422 for controlling the on-off of the second refrigerant branch, and further controlling the on-off of the second evaporator 420 .

[0078] When in the rapid cooling stage, the first switch 412 and the second switch 422 are both in the open state, the first evaporator 410 and the second evaporator 420 cool together, and the power of the compressor 500 is increased, so that the refrigerant is cooled quickly.

[0079] When the refrigerant liquid is cooled to the target temperature, only one of the first evaporator 410 and the second evaporator 420 needs to be connected, which is beneficial to energy saving and reducing the loss of electric energy.

[0080] The first evaporator 410 and the second evaporator 420 work together to achieve different states such as rapid cooling of the refrigerant and maintaining low temperature, which is more energy-saving, more intelligent, and provides a good user experience.

[0081] A controller 800 is also provided in the inner cavity 102 of the device. The controller 800 is connected to the compressor 500 , the switch component and the fan component 700 , and is used to control the switching of the compressor 500 , the switch component and the fan component 700 .

[0082] The upper surface of the door body 200 is also provided with a display panel 820, which is used to display the temperature of the refrigerant, so that the user can observe and adjust it conveniently. A temperature sensing element 810 is provided on the side wall of the refrigeration cavity 101, and the temperature sensing element 810 and the display panel 820 are both connected to the controller 800, and the display panel 820 is used to display the temperature detected by the temperature sensing element 810.

[0083] In some embodiments of the present application, in order to further improve the intelligence of the refrigeration system, a wifi module 830 and an NFC module 840 are also provided on the door body 200, and the wifi module 830 is signal-connected with the controller 800 and the NFC module 840.

[0084] The NFC module 840 can transmit information such as the temperature on the display panel 820 to the customer's mobile phone, and the user can control the target set temperature of the refrigerant through the mobile phone, which is more intelligent.

[0085] The specific signal transmission between the wifi module 830 and the controller 800 and the NFC module 840 is a prior art and is not the design focus of this application, so it will not be described in detail here.

[0086] In some embodiments of the present application, the temperature sensing element 810 is placed at a position close to the middle height of the side wall of the refrigeration cavity 101 to monitor the internal temperature of the refrigeration cavity 101. The specific position can be determined according to the volume size of the box 100 and specific system debugging.

[0087] There can be multiple temperature sensing elements 810 , which are dispersedly arranged at different heights of the refrigeration cavity 101 to more comprehensively obtain the temperature of the refrigeration cavity 101 . The controller 800 calculates the average temperature of the temperature sensing elements 810 to adjust the refrigeration.

[0088] The NFC module 840 is pre-buried in the upper right area of ​​the front side of the door body 200 .

[0089] The display panel 820 is installed in the area directly above the door body 200 for easy observation.

[0090] The wifi module 830 is integrated on the display panel 820. The NFC module 840 is connected to the display panel 820 via a connection line.

[0091] The user selects and sets the preset temperature of the refrigeration cavity 101 on the display panel 820 or the mobile phone APP according to the needs. The display panel 820 or the mobile phone APP will feed back the support instructions to the controller 800. The controller 800 outputs the control instructions according to the requirements to control the compressor 500, the fan component 700, the switch component, etc. to perform corresponding work.

[0092] When it is detected that the temperature in the refrigeration cavity 101 rises, or when food that needs to be frozen is placed in the refrigeration cavity 101, the controller 800 starts the fast intelligent cooling mode.

[0093] The rapid cooling mode is controlled according to the target temperature, and the temperature sensing element 810 feeds back the detected temperature to the controller 800. The controller 800 starts the compressor 500 and the switch element, and turns on the first evaporator 410 and the second evaporator 420 at the same time, outputs the maximum refrigeration capacity, and cools the refrigeration inner cavity 101. After reaching the preset temperature T1 of the rapid intelligent cooling mode, the controller 800 sends a command to jump out of the intelligent mode and automatically enters the low-speed cooling operation stage. The controller 800 controls the first switch element 412 or the second switch element 422 to close, and one of the first evaporator 410 and the second evaporator 420 works, and slowly continues to cool to the target storage temperature T0 (T1>T0).

[0094] When the detection element detects that the temperature in the refrigeration inner cavity 101 reaches the preset temperature T0, the controller 800 controls the compressor 500 to stop.

[0095] refer to Figure 7 The rear side of the door body 200 is connected to the box body 100 in a hinged manner to open or close the refrigeration cavity 101.

[0096] A heat-insulating inner cavity is formed between the box shell 110 and the box inner liner 120 , and a heat-insulating layer is formed in the heat-insulating inner cavity.

[0097] The door body 200 specifically includes a door body outer shell 210 and a door body inner shell 220. An insulating inner cavity is also formed between the door body outer shell 210 and the door body inner shell 220 to reduce cold air leakage.

[0098] Combination Fig. 9 In the prior art, a sealing strip 230 is formed on the lower surface of the door body 200. When the door body 200 is closed, the sealing strip 230 is connected to the box frame 300 to improve the sealing between the box frame 300 and the door body 200.

[0099] Specifically, the sealing strip 230 is disposed on the lower surface of the door body inner liner 220 , and the sealing strip 230 is fixed to the lower surface of the door body inner liner 220 by bonding.

[0101] Specifically, a box frame 300 is further disposed around the opening of the box body 100 , and a sealing surface 310 is formed on the upper surface of the box frame 300 .

[0102] A sealing strip 230 is installed at the bottom of the door body 200. When the door body 200 is in a closed state, the sealing strip 230 is in contact with and connected to the sealing surface 310, completely sealing the peripheral side of the door body 200 to reduce the amount of cold air transported outward.

[0103] The box frame 300 is arranged on the surrounding side of the opening position of the refrigeration cavity 101. Specifically, the box frame 300 is connected to the box shell 110 and the box liner 120. The thermal insulation cavity is formed between the box frame 300, the box shell 110 and the box liner 120. An insulation layer is formed in the thermal insulation cavity to improve the refrigeration effect of the refrigeration equipment and reduce the loss of cold.

[0104] In some embodiments of the present application, an installation groove 221 opening toward the sealing surface 310 is formed on the peripheral side of the door body inner liner 220 , and an installation throat is formed at the opening position of the installation groove 221 , and the size of the installation throat is smaller than the installation groove 221 .

[0105] Specifically, the mounting groove portion 221 forms a groove structure extending upward on the mating surface.

[0106] The sealing strip 230 is made of rubber material and includes a mounting portion 231 and a sealing portion 232 . The mounting portion 231 and the sealing portion 232 are integrally formed.

[0107] A buckle portion that tapers away from the sealing portion 232 is formed on the mounting portion 231 . The mounting portion 231 is buckled onto the mounting throat portion via the buckle portion. The sealing portion 232 is located outside the mounting groove portion 221 .

[0108] The buckle portion includes a clamping strip formed on both sides of the mounting portion 231. During installation, the clamping strip shrinks inwardly under the action of the mounting throat. After the installation is completed, the lower end of the clamping strip is clamped on the upper side of the mounting throat, and then the mounting portion 231 is completely connected in the mounting groove portion 221.

[0109] The above-mentioned installation method of the sealing strip 230 can improve the installation efficiency and facilitate assembly and disassembly. After the sealing strip 230 is aged and damaged, it is convenient to disassemble and replace it.

[0112] During installation, the external connection part 330 is covered on the outside of the box shell 110 , and the internal connection part 320 is connected to the box body 120 .

[0113] The inner connection part 320 and the outer connection part 330 can realize the connection between the box frame 300 and the box body 100, and reduce the connection gap between the box body 100, thereby ensuring the sealing effect of the heat-insulating inner cavity in the box body 100. The structure is simple and the installation is convenient and quick. The sealing surface 310 on the top of the box frame 300 can better contact with the sealing strip 230 to avoid leakage of cold in the refrigeration inner cavity 101.
