[0052] The following disclosure provides many different embodiments or examples for implementing different structures of the present utility model. To simplify the disclosure of the present utility model, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present utility model. In addition, the present utility model may repeat reference numerals and / or reference letters in different examples.

In addition, the present utility model provides examples of various specific processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0053] The refrigeration device in this application generally includes a box body, a door body, and a refrigeration system. Among them, at least one 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 accessing items.

[0054] Among them, the refrigeration system performs the refrigeration cycle of the refrigeration device by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation to achieve refrigeration of the items in the box body.

[0055] The low-temperature and low-pressure refrigerant enters the compressor, and the compressor compresses it into a refrigerant gas in a high-temperature and high-pressure state 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.

[0056] The expansion valve expands the high-temperature and high-pressure liquid-phase refrigerant formed by condensation in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can refrigerate the items in the box body by utilizing the latent heat of evaporation of the refrigerant.

[0057] Reference Figures 1-5 , this application proposes a refrigeration device, specifically a cold cabinet, which includes a box body 100, a box frame 130, and a door body 200. The box body 100 includes an outer shell 110 and an inner container 120, and a refrigeration inner cavity with an upward opening is formed in the inner container 120.

[0058] The opening of the refrigeration inner cavity serves as an introduction port for placing the items to be refrigerated into the refrigeration inner cavity or taking out the refrigerated items from the refrigeration inner cavity.

[0059] The box frame 130 is arranged on the periphery of the opening position of the refrigeration inner cavity. Specifically, the box frame 130 is respectively connected to the outer shell 110 and the inner liner 120. A heat preservation inner cavity is formed between the box frame 130, the outer shell 110 and the inner liner 120, and a heat preservation layer is formed in the heat preservation inner cavity to reduce the loss of cold quantity and improve the refrigeration effect of the refrigeration equipment.

[0060] The rear side of the door body 200 is connected to the box body 100 in a hinged manner for opening or closing the refrigeration inner cavity.

[0061] The door body 200 includes a door body outer shell and a door body inner liner. A heat preservation inner cavity is also formed between the door body outer shell and the door body inner liner, and a heat preservation layer is formed in the heat preservation inner cavity to reduce the outward transfer of cold quantity from the door body 200.

[0062] In the prior art, the door seal 300 is arranged between the horizontal planes of the door body 200 and the box frame 130. After being cooled, the door seal 300 is connected and deformed with the door body 200, resulting in a gap between the door body 200 and the box frame 130, with poor sealing effect, and there are problems such as cumbersome positioning and possible skew between the door body 200 and the box frame 130.

[0063] To solve the above problems, specifically referring to Figures 4-8 , in this application, a first sealing portion 210 is formed on the outer peripheral side of the door body 200, and the first sealing portion 210 is specifically tapered along the direction close to the refrigeration inner cavity.

[0064] A second sealing portion 131 is formed on the inner peripheral side of the box frame 130. The second sealing portion 131 corresponds to the position of the first sealing portion 210 and the second sealing portion 131 is located outside the first sealing portion 210, and the shape of the second sealing portion 131 is adapted to that of the first sealing portion 210.

[0065] Specifically, the second sealing portion 131 is tapered along the direction away from the door body 200.

[0066] That is, both the first sealing portion 210 and the second sealing portion 131 are inwardly contracted along the top-down direction, respectively forming an inclined plane structure.

[0067] When the door body 200 is closed, the first sealing portion 210 on the door body 200 is located inside the second sealing portion 131. The inclined plane design of the first sealing portion 210 and the second sealing portion 131 plays a guiding role in the closing of the door body 200, and after closing, through the conical surface fit between the first sealing portion 210 and the second sealing portion 131, the misalignment of the door body 200 can be avoided, and the stability of the closing of the door body 200 is improved.

[0068] The door seal 300 is connected to the first sealing portion 210 for sealing the gap between the first sealing portion 210 and the second sealing portion 131 when the door body 200 is closed.

[0069] Specific reference Figure 5 The door seal 300 is disposed between the first sealing portion 210 and the second sealing portion 131 which are inclined, and the sealing effect can also be improved. When the door body 200 is cooled, its thickness direction will be deformed, and the deformation amount in this direction is defined as L1. The deformation amount L2 in the direction of the door seal 300 (i.e., the direction perpendicular to the first sealing portion 210) is relatively small. Therefore, the deformation gap formed between the door body 200 and the box frame 300 due to cooling is reduced, and the sealing effect of the door seal 300 is good.

[0070] In some embodiments of the present application, the first sealing portion 210 includes at least one sealing surface formed on the peripheral side of the door body 200, and the second sealing portion 131 includes at least one sealing surface formed on the peripheral side of the box frame 130. The sealing surfaces corresponding to the first sealing portion 210 and the second sealing portion 131 are in one-to-one correspondence.

[0071] In other words, when the first sealing portion 210 is the front sealing surface formed on the front side of the door body 200, the second sealing portion 131 is the corresponding front sealing surface formed on the front side of the box frame 130.

[0072] When the first sealing portion 210 is two side sealing surfaces formed on opposite sides of the door body 200, the second sealing portion 131 includes two side sealing surfaces formed on opposite sides of the box frame 130.

[0073] When the first sealing portion 210 is four sealing surfaces arranged in a ring on the peripheral side of the door body 200, the second sealing portion 131 is four sealing surfaces formed on the peripheral side of the box frame 130.

[0074] The door seal 300 is disposed on the corresponding first sealing portion 210. Taking the four sealing surfaces formed in a ring of the first sealing portion 210 as an example, the door seal 300 is also in a ring shape and is continuously disposed on the peripheral side of the first sealing portion 210.

[0075] The door seal 300 is fixed to the first sealing portion 210 by means of pasting or snap connection.

[0076] Combined with Figure 10 、 Figure 11 In an embodiment of the present application, the first sealing portion 210 is formed with an installation recess 211. The door seal 300 includes a sealing main body 320 and a snap connection portion 310. The sealing main body 320 and the snap connection portion 310 are integrally formed, and the snap connection portion 310 is connected into the installation recess 211.

[0077] The installation recess 211 is specifically an installation groove formed by inward depression on the surface of the first sealing portion 210. The clamping portion 310 of the door seal 300 is connected into the installation recess 211, and the sealing main body 320 is located outside the first sealing portion 210. When the door body 200 is closed, the sealing main body 320 is compressed between the first sealing portion 210 and the second sealing portion 131 for sealing the door body 200 and the box frame 130.

[0078] Specifically refer to Figure 5 、 Figure 9 In some embodiments of the present application, in order to further limit the closing position of the door body 200, a limiting structure is further formed between the door body 200 and the box frame 130.

[0079] Specifically, an upper support portion 220 is formed on the door body 200, and the upper support portion 220 faces the direction of the box frame 130.

[0080] The upper support portion 220 includes at least one horizontally arranged upper support portion 220 provided on the peripheral side of the first sealing portion 210, and the upper support portion 220 is located outside the first sealing portion 210.

[0081] Support convex portions 221 protruding towards the box body 100 are arranged at intervals on the upper support portion 220, and the height dimension of the support convex portions 221 is determined according to the actual model of the refrigeration equipment.

[0082] A lower support portion 132 adapted to the position of each upper support portion 220 is formed on the peripheral side of the box frame 130. In the closed state of the door body 200, the bottom of the support convex portion 221 is in contact connection with the lower support portion 132.

[0083] In some embodiments of the present application, the upper support portion 220 and the lower support portion 132 may be a set of support planes arranged up and down corresponding to each other on the front side of the refrigeration equipment, or may be two sets of support planes arranged oppositely on the front and back or left and right sides of the refrigeration equipment. Or, the upper support portion 220 and the lower support portion 132 are four sets of support planes arranged on the peripheral side of the refrigeration equipment.

[0084] Between each group of support planes, stable support is provided for the door body 200 through the support convex portions 221.

[0085] The support convex portion 221 is a rubber pad, which is used to provide support for the door body 200 to prevent the door seal 300 from being squeezed and deformed due to the excessive weight of the door body 200, affecting the service life of the door seal 300.

[0086] Specifically, an installation throat 212 is formed on the installation recess 211, and the size of the installation throat 212 is smaller than that of the installation recess 211.

[0087] The snap connection part 310 includes a snap connection end part 311, and the snap connection end part 311 is connected to the sealing main body 320 through an intermediate part.

[0088] The snap connection end part 311 tapers in a direction away from the sealing main body 320, and an assembly tip is formed on the front side of the snap connection end part 311 to facilitate insertion into the installation recess 211.

[0089] A limiting end face 312 is formed on one side of the snap connection end part 311 close to the sealing main body 320. The snap connection end part 311 is connected in the installation recess 211 through the installation throat 212, and the limiting end face 312 is located inside the installation throat 212.

[0090] The door seal 300 is also made of rubber material as a whole and has a certain elasticity. During installation, the snap connection end part 311 moves through the installation throat 212 into the installation recess 211. The snap connection part 310 is compressed under the action of the installation throat 212 until the snap connection part 310 completely passes through the installation throat 212, and then the snap connection part 310 resets, and its limiting end face 312 is snapped to the inside of the installation throat 212 to complete the installation of the door seal 300.

[0091] In some other embodiments of the present application, in combination Figure 11 , the box frame 130 further includes an outer connection part 133 and an inner connection part 134. The outer connection part 133 is used to connect to the outer shell 110, and the inner connection part 134 is used to connect to the inner tank 120.

[0092] The inner connection part 134 and the outer connection part 133 are respectively connection outer edge structures formed on the inner and outer sides of the box frame 130 and extending downward.

[0093] During installation, the outer connection part 133 covers the outside of the outer shell 110, and the inner connection part 134 is connected to the inner tank 120.

[0094] In some embodiments of the present application, in order to improve the connection stability between the box frame 130 and the outer shell 110 and the inner tank 120, a plugging groove opening with a downward opening is formed on the outer connection part 133 and / or the inner connection part 134, and the upper edge of the outer shell 110 and / or the inner tank 120 is plugged into the corresponding plugging groove opening.

[0095] This refrigeration device refrigerates the refrigeration inner cavity through a refrigeration system. The refrigeration system includes a compressor, a condenser, and an evaporator, and the compressor, the condenser, and the evaporator are connected through refrigeration pipelines.

[0096] The compressor and the condenser are installed in the device inner cavity, and the evaporator is attached to the outer wall of the inner tank 120 facing away from the refrigeration inner cavity.

[0097] The low temperature formed by the evaporator during operation passes through the inner tank 120 and is transmitted to the refrigeration inner cavity to cool the refrigeration inner cavity or the refrigeration medium in the refrigeration inner cavity.

[0098] The present application also provides a refrigeration device, which includes a box body 100, a door body 200, and a box frame 130.

[0099] The box body 100 has a refrigeration inner cavity formed therein with an upward opening, for placing and taking out refrigerated items.

[0100] The door body 200 is connected to one side of the box body 100 to open or close the refrigeration inner cavity.

[0101] The box frame 130 is connected to the box body 100 and is located on the peripheral side of the opening of the refrigeration inner cavity, for connecting the inner liner 120 and the outer shell 110 of the box body 100. A heat-insulating inner cavity is formed between the box frame 130, the inner liner 120, and the outer shell 110.

[0102] Wherein, inclined sealing parts are respectively formed on the box frame 130 and the door body 200, and a door seal 300 is arranged between the two sealing parts. The door seal 300 is configured to be fixed on the sealing part of the box frame 130 or the door body 200 for sealing the gap formed between the box frame 130 and the door body 200.

[0103] The sealing parts can be arranged in the following several ways, or a combination of some of these ways.

[0104] Method 1:

[0105] The sealing parts on the box frame 130 and the door body 200 are specifically a first sealing part 210 formed on the outer peripheral side of the door body 200 and a second sealing part 131 formed on the inner peripheral side of the box frame 130. The first sealing part 210 is specifically tapered along the direction close to the refrigeration inner cavity, and the second sealing part 131 is tapered along the direction away from the door body 200. The second sealing part 131 corresponds to the position of the first sealing part 210 and the second sealing part 131 is located outside the first sealing part 210.

[0106] When the door body 200 is closed, the first sealing part 210 on the door body 200 is connected to the inner side of the second sealing part 131. The inclined surface design of the first sealing part 210 and the second sealing part 131 plays a guiding role in the closing of the door body 200. After closing, through the conical surface fit between the first sealing part 210 and the second sealing part 131, the dislocation of the door body 200 can be avoided, and the stability of the closing of the door body 200 can be improved.

[0107] The door seal 300 is connected to the first sealing part 210 for sealing the gap between the first sealing part 210 and the second sealing part 131 when the door body 200 is closed.

[0108] Along the direction close to the refrigeration inner cavity, one or more sealing structures are formed on the first sealing portion 210, that is, at least one layer of door seal 300 is arranged at intervals to improve the sealing effect.

[0109] Method 2:

[0110] In order to further limit the closing position of the door body 200, a limiting structure is further formed between the door body 200 and the box frame 130 in this application.

[0111] Specifically, an upper support portion 220 is formed on the door body 200, and the upper support portion 220 faces the box frame 130.

[0112] The upper support portion 220 includes at least one horizontally arranged upper support surface provided on the peripheral side of the first sealing portion 210, and the upper support portion 220 is located outside the first sealing portion 210.

[0113] A lower support portion 132 adapted to the position of each upper support portion 220 is formed on the peripheral side of the box frame 130.

[0114] Support protrusions 221 extending toward the box body 100 are arranged at intervals on the upper support portion 220. In the closed state of the door body 200, the bottom of the support protrusion 221 is in contact connection with the lower support portion 132.

[0115] Alternatively, the support protrusion 221 can also be arranged on the lower support portion 132.

[0116] Method 3:
