[0037] Combination Figure 1-6 As shown, in some embodiments, the refrigerator includes: a housing 100 and a refrigeration insert 200. A refrigeration chamber 110 is provided inside the housing 100; the refrigeration insert 200 is arranged in the refrigeration chamber 110; wherein, when food is placed in the refrigeration chamber 110, the refrigeration insert 200 partially or completely penetrates into the food, and the refrigeration insert 200 performs heat exchange and refrigeration inside the food.

[0038] In the refrigerator provided by the embodiment of the present disclosure, by arranging the refrigeration insert 200 inside the refrigeration chamber 110, when food is placed inside the refrigeration chamber 110, the refrigeration insert 200 can penetrate into the food, and the inside of the food is refrigerated by heat exchange using the refrigeration insert 200. The food is frozen by heat exchange from the inside to the outside, the freezing efficiency of the food is improved, the freezing effect of the food is better, the preservation effect of the food is improved, and the cost of freezing and preserving the food is reduced.

[0039] Optionally, the refrigeration chamber 110 is a freezer. In this way, when food is placed in the refrigeration chamber 110 for freezing and preservation, the refrigeration insert 200 is inserted into the food, and the inside of the food is frozen by the refrigeration insert 200, so that the food is frozen from the inside out, thereby improving the preservation effect of the food.

[0040] Combination Figure 2 As shown, in one embodiment, the outer wall of the refrigeration chamber 110 is covered with a refrigerant coil 120. In this way, the refrigerant flows into the refrigerant coil 120 to evaporate and dissipate heat, so that the refrigerant coil 120 is cooled down, the refrigerant coil 120 exchanges heat with the refrigeration chamber 110, and the interior of the refrigeration chamber 110 is kept in a low temperature environment. While the food stored in the refrigeration chamber 110 is frozen by the refrigeration insert 200 inside, the outer surface of the food is also frozen by heat exchange with the environment of the refrigeration chamber 110, so that the inside and outside of the food are frozen at the same time, the overall freezing of the food is more uniform, the food will not be deformed, and the preservation effect of the food is better.

[0041] Optionally, the refrigerant coil 120 is connected to the refrigeration system of the refrigerator and is used as an evaporator of the refrigeration system. In this way, the refrigeration system of the refrigerator continuously supplies refrigerant to the refrigerant coil 120, so that the refrigerant inside the refrigerant coil 120 continuously evaporates, and the low temperature environment of the refrigeration chamber 110 is maintained.

[0042] It can be understood that in the embodiment of the present disclosure, the refrigerator is a direct cooling refrigerator, and refrigeration is achieved by the refrigerant coil 120 coated on the outer wall of the refrigeration chamber 110.

[0043] Combination Figure 3 As shown, in another embodiment, a refrigeration air duct 130 is provided on the rear side wall of the refrigeration compartment 110, and the refrigeration air duct 130 has a return air port 131 and an air outlet 132, both of which are connected to the refrigeration compartment 110, and an evaporator is provided inside the refrigeration air duct 130. In this way, the air inside the refrigeration compartment 110 is continuously sucked in through the refrigeration air duct 130, and the sucked air is blown out again into the refrigeration compartment 110 through the air outlet 132 after heat exchange with the evaporator, so that the refrigeration compartment 110 maintains a low temperature environment. While the food stored in the refrigeration compartment 110 is frozen by the refrigeration insert 200 inside, the outer surface of the food is also frozen by heat exchange with the environment of the refrigeration compartment 110, so that the inside and outside of the food are frozen at the same time, the overall freezing of the food is more uniform, the food will not be deformed, and the preservation effect of the food is better.

[0044] Optionally, the air outlet 132 is disposed in the upper region of the side wall of the refrigeration duct 130. In this way, due to the natural downward sinking characteristics of the cold air flow, the air outlet 132 is disposed in the upper region of the side wall of the refrigeration duct 130, so that the cold air flow blown out of the air outlet 132 can naturally sink in the refrigeration compartment 110, so that the temperature uniformity inside the refrigeration compartment 110 is better, and the preservation effect of the food is improved.

[0045] Optionally, the return air vent 131 is disposed in the lower area of ​​the side wall of the refrigeration air duct 130. In this way, due to the heat exchange of the food inside the refrigeration chamber 110, the temperature of the air in the lower area of ​​the refrigeration chamber 110 is relatively high, so the return air vent 131 is disposed in the lower area of ​​the side wall of the refrigeration air duct 130, and the return air vent 131 is used to inhale relatively high temperature air for heat exchange and refrigeration.

[0046] Optionally, the evaporator is connected to the refrigeration system of the refrigerator. In this way, the refrigeration system of the refrigerator continuously supplies refrigerant to the evaporator, so that the refrigerant inside the evaporator continues to evaporate, and the evaporator is in a low temperature state to exchange heat with the air flowing into the refrigeration air duct 130, thereby maintaining a low temperature environment inside the refrigeration chamber 110.

[0047] It can be understood that in the embodiment of the present disclosure, the refrigerator is an air-cooled refrigerator, and refrigeration is achieved by continuously sucking air into the refrigeration chamber 110 through the refrigeration air duct 130, exchanging heat, and then blowing it out again.

[0048] Combination Figure 1 As shown, in one embodiment, a front side wall of the refrigeration chamber 110 is provided with a take-in / take-out opening 111, one end of the refrigeration plug 200 is fixedly connected to the rear inner wall of the refrigeration chamber 110, and the other end is arranged toward the take-in / take-out opening 111. In this way, food can be taken in and out from the inside of the refrigeration chamber 110 through the take-in / take-out opening 111, and the end of the refrigeration plug 200 is arranged toward the take-in / take-out opening 111. When food is put into the refrigeration chamber 110 through the take-in / take-out opening 111, the end of the refrigeration plug 200 can smoothly penetrate into the inside of the food.

[0049] It can be understood that the side wall of the refrigeration compartment 110 that is open is the front side wall, and the side wall of the refrigeration compartment 110 that is opposite to the front side wall is the rear side wall.

[0050] Optionally, the refrigeration plug 200 is arranged horizontally. In this way, since the access opening 111 is arranged on the front side wall of the refrigeration chamber 110, the food has a horizontal position when it is put in through the access opening 111, and the end of the horizontally arranged refrigeration plug 200 can better penetrate into the food.

[0051] Optionally, a door 140 is provided at the opening of the refrigeration compartment 110, and the door 140 is movably connected to the housing 100, and the door 140 is used to close or open the opening. In this way, the opening of the refrigeration compartment 110 can be closed by the door 140, thereby improving the heat preservation effect of the refrigeration compartment 110 and reducing the leakage of cold energy.

[0052] Optionally, along the front-to-back direction of the refrigerating compartment 110, the length of the refrigerating plug 200 is greater than or equal to two-thirds of the length of the refrigerating compartment 110, and is less than the length of the refrigerating compartment 110. In this way, when the length of the refrigerating plug 200 is less than two-thirds of the length of the refrigerating compartment 110, the length of the refrigerating plug 200 is short, and the food placed in the refrigerating compartment 110 is not easily penetrated by the refrigerating plug 200. When the length of the refrigerating plug 200 is greater than or equal to the length of the refrigerating compartment 110, the length of the refrigerating plug 200 is large, which affects the storage space of the refrigerating compartment 110. Therefore, the length of the refrigerating plug 200 is set to be greater than or equal to two-thirds of the length of the refrigerating compartment 110, and less than the length of the refrigerating compartment 110, so that the end of the refrigerating plug 200 can smoothly penetrate into the food and freeze the inside of the food. At the same time, the portion of the refrigeration insert 200 that does not penetrate into the food can also exchange heat with the internal environment of the refrigeration chamber 110 to maintain a low temperature environment inside the refrigeration chamber 110, thereby achieving a better preservation effect of the refrigeration chamber 110.

[0053] Optionally, along the front-to-back direction of the refrigeration chamber 110, the length of the refrigeration plug 200 is equal to two-thirds of the length of the refrigeration chamber 110. In this way, the refrigeration plug 200 can reduce the impact on the storage space of the refrigeration chamber 110 and ensure that the end of the refrigeration plug 200 can smoothly penetrate into the food.

[0054] Optionally, the cross-sectional area of ​​the refrigeration plug 200 along the vertical direction gradually decreases from the rear side to the front side of the refrigeration chamber 110. In this way, the shape of the refrigeration plug 200 is conical, and the front end of the refrigeration plug 200, that is, the end of the refrigeration plug 200 facing the access opening 111 is relatively sharp, so that it can smoothly penetrate into the food.

[0055] Optionally, the cross section of the cooling plug 200 along the vertical direction is circular. In this way, the cooling plug 200 is conical in shape, and the outer wall of the cooling plug 200 is subjected to a relatively uniform force when penetrating into the food, and the cooling plug 200 is not easily damaged by the force. Moreover, the conical cooling plug 200 can smoothly penetrate into the food, reducing the difficulty of inserting the food.

[0056] Combination Figure 1 and Figure 4As shown, in one embodiment, an evaporation tube 210 is provided inside the refrigeration plug 200. In this way, the refrigerant flows into the evaporation tube 210 to evaporate and absorb heat, so that the temperature of the evaporation tube 210 is reduced, and the evaporation tube 210 exchanges heat with the refrigeration plug 200, thereby realizing the refrigeration of the refrigeration plug 200, and the inside of the food is refrigerated through the refrigeration plug 200. By providing the evaporation tube 210 to refrigerate the refrigeration plug 200, the evaporation tube 210 can be connected to the refrigeration system of the refrigerator, and the refrigerator's own refrigeration system is used to provide refrigerant, thereby reducing the refrigeration cost of the refrigeration plug 200.

[0057] Optionally, the rear end of the refrigeration plug 200 is embedded in the rear inner wall of the refrigeration chamber 110, a cavity is formed inside the refrigeration plug 200, and the evaporation tube 210 extends into the cavity of the refrigeration plug 200 along the rear wall of the refrigeration chamber 110. In this way, the connection stability between the refrigeration plug 200 and the rear inner wall of the refrigeration chamber 110 can be guaranteed, and the evaporation tube 210 can be smoothly extended into the cavity inside the refrigeration plug 200.

[0058] Optionally, the length of the evaporator tube 210 is greater than or equal to eight tenths of the length of the refrigeration plug 200, and is less than the length of the refrigeration plug 200. In this way, when the length of the evaporator tube 210 is less than eight tenths of the length of the refrigeration plug 200, the length of the evaporator tube 210 is relatively small, and the refrigeration area of ​​the evaporator tube 210 does not match the length of the refrigeration plug 200, resulting in poor overall temperature uniformity of the refrigeration plug 200 and reduced refrigeration effect of the refrigeration plug 200. When the length of the evaporator tube 210 is greater than or equal to the length of the refrigeration plug 200, the evaporator tube 210 cannot be laid inside the refrigeration plug 200. Therefore, the length of the evaporator tube 210 is set to be greater than or equal to eight tenths of the length of the refrigeration plug 200, and less than the length of the refrigeration plug 200, so that the length of the refrigeration area of ​​the evaporator tube 210 can match the length of the refrigeration plug 200, so that the refrigeration plug 200 can better exchange heat with the evaporator tube 210, improve the overall temperature uniformity of the refrigeration plug 200, and better refrigerate the inside of the food.

[0059] Optionally, the length of the evaporation tube 210 is equal to eight tenths of the length of the refrigeration plug 200. In this way, since the refrigeration plug 200 is a tapered structure, the evaporation tube 210 cannot be laid in the area near the tapered tip inside the refrigeration plug 200. Therefore, setting the length of the evaporation tube 210 equal to eight tenths of the length of the refrigeration plug 200 can ensure the length of the refrigeration area of ​​the evaporation tube 210 and enable the evaporation tube 210 to be laid reasonably.

[0060] Optionally, the outer wall of the evaporator tube 210 is connected to the inner wall of the refrigeration plug 200. In this way, the evaporator tube 210 can be more stably arranged in the refrigeration plug 200, and the outer wall of the evaporator tube 210 can more efficiently exchange heat with the inner wall of the refrigeration plug 200, and the heat exchange efficiency between the evaporator tube 210 and the refrigeration plug 200 is higher.

[0061] Optionally, the outer wall of the evaporation tube 210 is movably connected to the inner wall of the refrigeration plug 200, so that the evaporation tube 210 can be removed from the inside of the refrigeration plug 200. In this way, when the evaporation tube 210 is damaged, the evaporation tube 210 can be removed separately, which is convenient for maintenance of the evaporation tube 210 and reduces the cost of maintenance of the evaporation tube 210.

[0062] Exemplarily, the evaporator tube 210 is composed of two copper tubes connected together, one of the two copper tubes is attached to the inner wall of the refrigeration plug 200 along the rear end of the refrigeration plug 200 and extends to the front end of the refrigeration plug 200, and the other is attached to the opposite inner wall of the refrigeration plug 200 along the rear end of the refrigeration plug 200 and extends to the front end of the refrigeration plug 200. The two copper tubes are connected at the front end inside the refrigeration plug 200.

[0063] Optionally, the evaporation tube 210 is connected to the refrigeration system of the refrigerator. In this way, the refrigerator's own refrigeration system is used to provide refrigerant for the evaporation tube 210, and there is no need to set up an independent refrigeration system for the evaporation tube 210, which reduces the refrigeration cost of the refrigeration insert 200, thereby reducing the production cost of the refrigerator.

[0064] Optionally, the evaporation tube 210 is connected in parallel with the evaporator in the refrigeration system between the outlet of the condenser and the inlet of the compressor. In this way, the refrigerant flowing out of the condenser can flow to the evaporator and the evaporation tube 210 respectively, and while ensuring the refrigeration function of the refrigerator, the refrigerant is supplied to the evaporation tube 210, so that the evaporation tube 210 also has refrigeration capacity.

[0065] Exemplarily, the refrigeration system of the refrigerator is composed of an evaporator, an evaporating tube 210, a condenser, a compressor and a throttling element, etc. The outlet end of the compressor is connected to the inlet end of the condenser, and the outlet end of the condenser is respectively connected to the inlet end of the evaporator and the evaporating tube 210, and the outlet ends of the evaporator and the evaporating tube 210 are both connected to the inlet end of the compressor, and a throttling element is connected between the evaporator and the condenser, and a throttling element is also connected between the evaporating tube 210 and the condenser.

[0066] Optionally, a first throttle valve is provided between the inlet end of the evaporator and the outlet end of the condenser, and a second throttle valve is provided between the inlet end of the evaporation tube 210 and the outlet end of the condenser. In this way, the refrigerant flow of the evaporator and the evaporation tube 210 can be controlled by the first throttle valve and the second throttle valve, thereby controlling the refrigeration capacity of the evaporator and the evaporation tube 210.

[0067] Combination Figure 5 and Figure 6 As shown, in one embodiment, the outer wall of the refrigeration plug 200 is provided with a heating part 300, which can heat the outer wall of the refrigeration plug 200 to thaw the frozen position of the food and the refrigeration plug 200. In this way, the outer wall of the refrigeration plug 200 is easy to freeze with the internal structure of the food, making it difficult to take out the food. Therefore, the heating part 300 is provided on the outer wall of the refrigeration plug 200. When it is necessary to take out the food, the outer wall of the refrigeration plug 200 is heated by the heating part 300, so that the outer wall of the refrigeration plug 200 and the frozen position of the food are thawed, which is convenient for taking out the food. At the same time, the heating of the outer wall of the refrigeration plug 200 can thaw the food from the inside to the outside, improve the thawing efficiency of the food, and facilitate the consumption of the food after taking it out.

[0068] Optionally, the heating part 300 is a heating wire. In this way, by arranging the heating wire on the outer wall of the refrigeration insert 200, the heating wire has low cost and high heat generation, and can efficiently heat the outer wall of the refrigeration insert 200, so that the food is thawed quickly.

[0069] Optionally, a groove 220 is formed on the outer wall of the refrigeration plug 200, and the heating part 300 is embedded in the groove 220. In this way, the heating part 300 is embedded in the groove 220 of the outer wall of the refrigeration plug 200, so that the heating part 300 is hidden in the outer wall of the refrigeration plug 200. When the refrigeration plug 200 penetrates into the food, the risk of interference between the heating part 300 and the food is reduced, and the risk of the heating part 300 falling off is reduced, while the insertion efficiency of the refrigeration plug 200 is improved.

[0070] Optionally, along the direction perpendicular to the outer wall of the cooling insert 200, the depth of the groove 220 is greater than the thickness of the heating portion 300. In this way, the heating portion 300 can be completely hidden inside the groove 220, and the heating portion 300 is prevented from protruding from the outer wall of the cooling insert 200, the heating wire does not interfere with the food, and the cooling insert 200 can smoothly penetrate into the food.

[0071] Optionally, a plurality of refrigeration plugs 200 are arranged inside the refrigeration chamber 110, each refrigeration plug 200 is arranged along the front-to-back direction of the refrigeration chamber 110, and the rear end of each refrigeration plug 200 is fixedly connected to the rear side wall of the refrigeration chamber 110, and the front end of each refrigeration plug 200 is arranged toward the access opening 111 of the refrigeration chamber 110. In this way, when a plurality of food materials or a large amount of food materials are stored inside the refrigeration chamber 110, a plurality of refrigeration plugs 200 can simultaneously penetrate into the food materials to refrigerate the inside of the food materials, thereby improving the preservation effect of the food materials.

[0072] Optionally, a heating portion 300 is provided on the outer side wall of each cooling insert 200 .

[0073] Optionally, a plurality of heating buttons are provided on the front side wall of the door body 140, and each heating button corresponds to a heating wire on a refrigeration plug 200, and can control the on and off of the heating wire on the refrigeration plug 200. In this way, when taking out food, the user can press the corresponding heating button according to the refrigeration plug 200 through which the food is taken out, so that the heating part 300 on the outer wall of the refrigeration plug 200 is powered on and heated, thereby thawing the food, facilitating the taking out of the food, and improving the user experience.
