[0058] Next, combine Figures 1 to 12 , the top plate assembly 100 of an embodiment of the present utility model is described.

[0059] refer to Figure 1 and Figure 2 As shown, the utility model provides a top plate assembly 100 of an embodiment of the first aspect, the top plate assembly 100 includes a main body 110, the main body 110 is provided with a mounting groove 111, the mounting groove 111 is used to install the refrigeration assembly 200, one end of the mounting groove 111 forms a mounting port 1111, the inner side of the mounting groove 111 forms a mounting space 1112, the refrigeration assembly 200 is inserted into the mounting space 1112 through the mounting port 1111, an inner side wall 1113 of the mounting groove 111 is away from one end of the mounting port 1111 and is inclined toward the mounting space 1112, and the inner side wall 1113 abuts against the refrigeration assembly 200.

[0060] According to the top plate assembly 100 provided in the embodiment of the utility model, the top plate assembly 100 is provided with a mounting groove 111, and the mounting groove 111 is formed in the mounting groove 111 for mounting the refrigeration assembly 200, and the inner side wall 1113 of the mounting groove 111 is inclined in the direction close to the mounting space 1112. In this embodiment, the inner side wall 1113 abuts against the refrigeration assembly 200. It can be understood that the inner side wall 1113 is used to support the refrigeration assembly 200, and the refrigeration assembly 200 can be limited on the inner side wall 1113, so that the refrigeration assembly 200 is difficult to slide downward and is fixed on the top plate assembly 100. The inclined setting of the inner side wall 1113 can realize the reliable connection between the top plate assembly 100 and the refrigeration assembly 200, improve the reliability of the fixation of the refrigeration assembly 200, and thus avoid the possibility of the refrigeration assembly 200 shaking during use. The inner wall 1113 is inclined, and the assembly of the top plate assembly 100 and the refrigeration assembly 200 is simple. The refrigeration assembly 200 can be limited and positioned on the upper side of the inner wall 1113, thereby improving installation efficiency and production efficiency.

[0061] In this embodiment, the top plate assembly 100 can be used as an independent component, and the top plate assembly 100 can be independently produced, sold and installed, which helps to simplify the manufacturing process and improve production efficiency. Modular and independent design helps to optimize the production process and reduce manufacturing costs.

[0062] When the top plate assembly 100 is applied to the refrigeration device 300, it can be understood that the top plate assembly 100 is arranged on the top of the refrigeration device 300, and correspondingly, the refrigeration assembly 200 is arranged on the top of the refrigeration device 300, which can not only reduce the space occupied by the refrigeration assembly 200 inside the refrigeration device 300, but also increase the available space inside the refrigeration device 300, which helps to improve the space utilization rate. Among them, the available space can also be understood as the space occupied by the refrigeration compartment 330.

[0063] Compared with setting the refrigeration assembly 200 inside the refrigeration equipment 300, the top plate assembly 100 of this embodiment can be used to install the refrigeration assembly 200, and the refrigeration assembly 200 can be set on the top of the refrigeration equipment 300, which is convenient for users to repair, clean or replace the refrigeration assembly 200, reducing the difficulty of maintaining the refrigeration assembly 200, thereby improving the maintainability of the refrigeration equipment 300. Taking the unchanged height of the refrigeration equipment 300 as an example, setting the refrigeration assembly 200 on the top plate assembly 100 can avoid raising the height of the refrigeration compartment 330 when the refrigeration assembly 200 is set at the bottom of the refrigeration equipment 300, that is, setting the refrigeration assembly 200 on the top plate assembly 100 helps to lower the height of the refrigeration compartment 330, making it convenient for users to access items in the refrigeration compartment 330. Taking the variable height of the refrigeration equipment 300 as an example, setting the refrigeration assembly 200 on the top plate assembly 100 helps to expand the space of the refrigeration compartment 330 downward, and the space of the refrigeration compartment 330 becomes larger, which can improve the available space of the refrigeration equipment 300.

[0064] Combination Fig.10 and Fig.12 As shown, the mounting groove 111 is used to mount the refrigeration assembly 200, the mounting groove 111 can be used to mount the plate body 220 of the refrigeration assembly 200, the plate body 220 is used to mount the compressor and the evaporator of the refrigeration assembly 200, and the inner side wall 1113 abuts against the plate body 220. The plate body 220 has a simple structure, which helps to simplify the assembly process of the top plate assembly 100 and the refrigeration assembly 200 and improve the assembly efficiency.

[0065] The following description will be made by taking the installation groove 111 used to install the plate body 220 of the refrigeration assembly 200 as an example.

[0066] Combination Figure 3 and Figure 4As shown, the top plate assembly 100 further includes a first seal 121, which is disposed on the inner side wall 1113, and is used to seal and connect the mounting groove 111 and the refrigeration assembly 200. In this embodiment, the first seal 121 is disposed on the inner side wall 1113, which can achieve sealing of the top plate assembly 100 and the refrigeration assembly 200. It can be understood that when a refrigeration compartment 330 is disposed at the bottom of the top plate assembly 100, the sealing of the top plate assembly 100 and the refrigeration assembly 200 can prevent the coldness of the refrigeration compartment 330 from being lost from the connection, which helps to maintain the refrigeration effect of the refrigeration equipment, improve the refrigeration effect and energy efficiency of the refrigeration equipment 300, and reduce energy consumption.

[0067] The first seal 121 may be fixedly connected to the inner side wall 1113, or may be clamped between the inner side wall 1113 and the refrigeration assembly 200. When the top plate assembly 100 further includes the refrigeration assembly 200, the first seal 121 may also be fixedly connected to the refrigeration assembly 200. When the refrigeration assembly 200 is installed in the installation groove 111, the first seal 121 abuts against the inner side wall 1113 to achieve sealing between the installation groove 111 and the refrigeration assembly.

[0068] Combination Figure 4 The inner side wall 1113 includes a first side wall 1113-1 and a second side wall 1113-2 arranged along the insertion direction of the refrigeration assembly 200, the second side wall 1113-2 is connected to the first side wall 1113-1 and forms an angle, and at least one of the first side wall 1113-1 and the second side wall 1113-2 is provided with a first sealing member 121. In this embodiment, the first side wall 1113-1 and the second side wall 1113-2 of the mounting groove 111 form an angle, and the first side wall 1113-1 and the second side wall 1113-2 are not on the same plane, that is, the first side wall 1113-1 and the second side wall 1113-2 are on two different planes, and a corner can be formed at the connection between the first side wall 1113-1 and the second side wall 1113-2, so that the conduction leakage of cold can be effectively prevented. The heat convection of different temperatures on both sides of the top plate assembly 100 needs to be conducted through the corners. It can also be understood that due to the existence of the corners, the cold at different temperatures on both sides of the top plate assembly 100 is difficult to conduct, which reduces the convection efficiency and optimizes the sealing effect. At least one of the first side wall 1113-1 and the second side wall 1113-2 is provided with a first seal 121, which can improve the sealing effect and the isolation effect of the top plate assembly 100, which can not only prevent the leakage of cold, but also prevent external heat from entering the refrigeration chamber 330.

[0069] Among them, the first seal 121 can be set on the first side wall 1113-1, can also be set on the second side wall 1113-2, and can also be set on the first side wall 1113-1 and the second side wall 1113-2. When the first seal 121 is set on the first side wall 1113-1 and the second side wall 1113-2, it can also be understood that the first side wall 1113-1 and the second side wall 1113-2 are both sealed and connected to the refrigeration assembly 200 through the first seal 121, which can achieve double sealing and better sealing effect. At the same time, the double seal has multiple first seals 121, and the compression required for each first seal 121 is reduced, and the compression force required to be applied is reduced. The user's operating force on the top plate assembly 100 during installation and disassembly is reduced, which improves the user experience.

[0070] The second side wall 1113-2 forms an angle with the first side wall 1113-1, and the angle may be an obtuse angle. The angle may also be a right angle, in which case the first side wall 1113-1 may extend straight downward, the second side wall 1113-2 may be arranged horizontally, and the angle between the first side wall 1113-1 and the second side wall 1113-2 may be a right angle; of course, the first side wall 1113-1 may be close to the installation space 1112, the second side wall 1113-2 may form a right angle with the first side wall 1113-1, and the second side wall 1113-2 may extend obliquely upward. In some other embodiments, the first side wall 1113-1 and the second side wall 1113-2 may also be an acute angle. The angle may be set according to actual needs and is not limited here.

[0071] In the direction away from the installation opening 1111, the first side wall 1113-1 is inclined toward the center of the installation space 1112, and one end of the first side wall 1113-1 away from the installation opening is connected to the second side wall 1113-2, and the second side wall 1113-2 is horizontally arranged. In this embodiment, the first side wall 1113-1 is inclined toward the installation space 1112, which helps to guide the fall of the refrigeration assembly 200; the second side wall 1113-2 is horizontally arranged, and the second side wall 1113-2 is used to support the refrigeration assembly 200. When the refrigeration assembly 200 drops to the second side wall 1113-2, it will be limited by the second side wall 1113-2, that is, the refrigeration assembly 200 can be limited on the second side wall 1113-2. The structure of the installation groove 111 is simple, and can improve the reliability of the combination of the top plate assembly 100 and the refrigeration assembly 200.

[0072] Combination Figure 4As shown, the installation groove 111 also includes a third side wall 1113-3, the third side wall 1113-3 is connected to the end of the second side wall 1113-2 away from the first side wall 1113-1, and the third side wall 1113-3 is inclined toward the installation space 1112. In this embodiment, the third side wall 1113-3 is inclined toward the inside of the installation groove 111 along the second side wall 1113-2 downward, and the third side wall 1113-3 can guide the assembly of the refrigeration assembly 200, so that the refrigeration assembly 200 can descend along the third side wall 1113-3, which helps the refrigeration assembly 200 to accurately fall to the installation position and provide a stable support effect. The provision of the third side wall 1113-3 can increase the contact area between the top plate assembly 100 and the refrigeration assembly 200, thereby improving the reliability and stability of the top plate assembly 100 for support.

[0073] Combination Figure 4 and Fig.12 As shown, the body 110 includes a top surface, and the refrigeration assembly 200 includes a limit plate 210, a plate body 220 and a compressor. The plate body 220 is inserted into the installation space 1112, the limit plate 210 is connected to the plate body 220, the top surface is used to limit the limit plate 210, and the compressor is arranged on the side of the limit plate 210 facing away from the plate body 220. In this embodiment, the limit plate 210 covers the installation opening 1111, which can also be understood as the limit plate 210 is covered on the upper side of the installation opening 1111, and the edge position of the limit plate 210 is located at the top surface of the body 110. The top surface of the body 110 cooperates with the installation groove 111 to achieve double fixation of the refrigeration assembly 200, which helps to ensure that the top plate assembly 100 and the refrigeration assembly 200 are fixed and stable.

[0074] The top plate assembly 100 further includes a second seal 122, which is disposed on the top surface, and the second seal 122 is disposed on the periphery of the mounting groove 111, and the second seal 122 is used to seal and connect the top surface and the limiting plate 210. In this embodiment, the second seal 122 can effectively seal the gap between the top surface of the body 110 and the limiting plate 210, improve the tightness of the connection between the body 110 and the limiting plate 210, help reduce the conduction of energy at the connection between the top surface and the limiting plate 210, reduce the loss of cold and avoid the transfer of heat to the refrigeration compartment 330, thereby helping to maintain the stability of the temperature of the refrigeration compartment 330 and improve the energy efficiency of the refrigeration device 300.

Among them, the first seal 121 includes at least one of a sealing strip and a sealing ring. The first seal 121 may be a sealing strip, the thickness of which is greater than the gap between the inner side wall 1113 of the mounting groove 111 and the refrigeration assembly 200. When the refrigeration assembly 200 is inserted into the mounting groove 111, the sealing strip is squeezed to achieve the purpose of sealing. Of course, the first seal 121 may also be a sealing ring, which is arranged on the inner side wall 1113 of the mounting groove 111 and is arranged around the inner side wall 1113, so as to ensure that the cold is difficult to leak from the four sides of the mounting groove 111. Similarly, the second seal 122 includes at least one of a sealing strip and a sealing ring. The sealing strip and the sealing ring may be a sponge pad, a soft rubber pad, or an airbag seal. The first sealing member 121 and the second sealing member 122 may be arranged according to actual needs and are not limited here.

[0076] Combination Fig.11 In some embodiments, the top plate assembly 100 further includes a reinforcing plate 170, which is connected to the upper side of the body 110. The reinforcing plate 170 is provided with a connecting hole 171 connected to the mounting groove 111, and the refrigeration assembly 200 can be inserted through the connecting hole 171 and the mounting port 1111 and inserted into the mounting groove 111.

Of course, the reinforcement 160 can also be a stainless steel reinforcement 160, an aluminum reinforcement 160, a plastic reinforcement 160, etc.

[0090] When the roof assembly 100 further includes the heat insulating member 140, the reinforcing member 160 and the heat insulating member 140 are connected by the first connecting member 146. In this embodiment, the reinforcing member 160 and the heat insulating member 140 are connected by the first connecting member 146, which can reduce the difficulty of assembling the reinforcing member 160 and the heat insulating member 140.

[0091] Combination Figure 6 , the thermal insulation member 140 is provided with a first connection hole, and the reinforcement member 160 is provided with a second connection hole as an example for description.

[0092] The first connecting member 146 is sequentially inserted into the first connecting hole and the second connecting hole to realize the connection between the heat insulating member 140 and the reinforcing member 160. In this embodiment, the heat insulating member 140 and the reinforcing member 160 are connected by a connecting member, which can not only effectively simplify the assembly process, reduce the installation steps and time, and improve the assembly efficiency, but also reduce the number of parts required for assembly, thereby reducing the manufacturing cost.

[0095] Combination Figure 2 , Figure 7 and Figure 8 As shown, the heat insulating member 140 is provided with a fixing portion 145, and a fixing channel 1451 is provided inside the fixing portion 145. The fixing channel 1451 is used to fix the mounting bracket 320, and the mounting bracket 320 is used to fix the door body 310 of the refrigeration device 300. The side plate 130 is provided with a first fixing hole, and the reinforcing member 160 is provided with a second fixing hole 161. The fixing portion 145 is sequentially penetrated through the first fixing hole and the second fixing hole 161. In this embodiment, the fixing portion 145 is penetrated through the side plate 130 and the reinforcing member 160. The reinforcing member 160 can not only strengthen the strength of the side plate 130, but also provide a stable support for the fixing portion 145, bear the weight of the door body 310 and the pull load when the door is opened, help maintain the stability of the mounting bracket 320 and the door body 310, and prevent the mounting bracket 320 and the door body 310 from loosening or swinging during use.

[0096] The fixing portion 145 is disposed on the heat insulating member 140. It is understood that the fixing portion 145 is a part of the heat insulating member 140 and has a heat insulating function. The fixing portion 145 can ensure the heat insulating effect of the mounting bracket 320 and the top plate assembly 100, and can prevent the cold of the refrigerating compartment 330 from being transferred to the mounting bracket 320. At the same time, the fixing portion 145 is disposed on the heat insulating member 140, which helps to maintain the structural integrity of the heat insulating member 140 and helps to prevent the heat insulating performance of the heat insulating member 140 from being reduced due to adding other connecting components to the heat insulating member 140.

[0097] It should be noted that the fixing portion 145 and the thermal insulation member 140 may be integrally formed, or the fixing portion 145 may be connected to the thermal insulation member 140, and the connection may be by bonding, snapping, plugging, or other connection methods, which may be selected according to actual needs.

[0099] The side panel 130 includes at least one of a metal panel, a ceramic panel, and a plastic panel. The side panel 130 may be a metal panel, and the metal panel may be a stainless steel panel, an aluminum panel, a magnetic panel, etc. The metal panel may be used to adsorb the magnetic strip in the sealing strip of the door body 310 of the refrigeration device 300, thereby enhancing the sealing effect between the side panel 130 and the door body 310. The side panel 130 may also be a ceramic panel or a plastic panel, and the selection of the side panel 130 may be set according to actual needs.

[0100] The main body 110 including the heat-insulating layer is described below.

[0101] The body 110 includes a heat preservation layer. In this embodiment, the body 110 can be used as a heat preservation layer to achieve the heat preservation effect of the top plate assembly 100 on the refrigeration device 300, effectively reduce the cold conduction of the refrigeration device 300 to the outside, and maintain the low temperature environment inside the refrigeration device 300. At the same time, the body 110 can be used as a heat preservation layer, which can save the need for additional heat preservation structures, reduce the space occupied by the top plate assembly 100, and thus increase the storage capacity of the refrigeration compartment 330.

[0102] In this embodiment, the main body 110 is provided with a mounting groove 111, that is, the insulation layer is provided with a mounting groove 111, and the refrigeration component 200 can be directly assembled on the insulation layer, which not only makes the structure of the refrigeration equipment 300 more compact, but also prevents the heat generated by the refrigeration component 200 from being transferred to the refrigeration chamber 330, affecting the refrigeration effect.

[0103] When the body 110 includes a heat-insulating layer, the heat-insulating layer may be an integral structure, that is, the body 110 is an integral structure; the heat-insulating layer may also be detachable. Figure 5 As shown, the insulation layer includes a first insulation layer 1101 and a second insulation layer 1102, the first insulation layer 1101 is provided with a mounting groove 111, the second insulation layer 1102 is connected to the first insulation layer 1101, and the heating element 150 is arranged between the second insulation layer 1102 and the side plate 130. In this embodiment, compared with the insulation layer being an integral structure, splitting the insulation layer into the first insulation layer 1101 and the second insulation layer 1102 can simplify the manufacturing process, and the first insulation layer 1101 and the second insulation layer 1102 are small in size, which is convenient for transportation and handling. At the same time, when the insulation layer needs to be repaired or replaced, the disassembly structure only requires replacing the damaged components without replacing the entire insulation layer, which reduces the difficulty and cost of maintenance.

[0104] Combination Figure 2 and Figure 6 As shown, the top plate assembly 100 further includes a top reinforcement 190, which is disposed on the top of the body 110, disposed on the periphery of the body 110, and connects the body 110 and the side plate 130. In this embodiment, the top reinforcement 190 can effectively improve the pressure and load bearing capacity of the top plate, effectively increase the strength of the top plate, and thus improve the stability of the refrigeration device 300. The arrangement of the top reinforcement 190 on the periphery of the top plate helps to evenly distribute the load, reduce the pressure of the local stress point, and reduce the risk of possible deformation or damage of the top plate.

[0105] When the roof assembly 100 further includes the reinforcing plate 170, one end of the roof reinforcement 190 is disposed between the reinforcing plate 170 and the body 110, and the other end of the roof reinforcement 190 is connected to the side plate 130.

The heating element 150 is in contact with the side plate 130, and the heating element 150 can directly heat the side plate 130, which can improve the heat transfer efficiency, thereby improving the condensation treatment efficiency of the side plate 130. When the main body 110 is a thermal insulation layer, that is, the heating element 150 is arranged between the thermal insulation layer and the side plate 130. The thermal insulation layer can not only prevent the coldness of the refrigeration chamber 330 from being transferred to the side plate 130, but also keep the heating element 150 warm, that is, prevent the heat of the heating element 150 from being lost, not only can the heat of the heating element 150 fully act on the side plate 130, improve the heating effect of the side plate 130, but also improve the heat utilization rate of the heating element 150, thereby reducing the energy consumption required by the heating element 150.

[0109] When the top plate assembly 100 also includes a reinforcement 160, the heating element 150 can be clamped between the main body 110 and the reinforcement 160, and the heat of the reinforcement 160 is transferred to the side plate 130 through the reinforcement 160. At this time, the reinforcement 160 plays a heat conductive role, which can ensure that the heat of the heating element 150 can be evenly distributed on the side plate 130, improve the temperature uniformity of the side plate 130, and further ensure that the condensation on the side plate 130 can be fully removed.

[0110] It should be noted that only one reinforcement member 160 may be provided, and in this case, the heating member 150 may be clamped between the body 110 and the reinforcement member 160, or may be clamped between the body 110 and the side plate 130.

In this embodiment, the top plate assembly 100 is provided with a cavity 181 for installing the compressor, and the cavity 181 can provide a relatively independent space for the compressor, which helps to prevent the heat generated by the compressor from being transferred to other structures of the refrigeration device 300 to cause an impact, such as preventing the top plate assembly 100 from insulating the compressor and preventing the heat of the compressor from being transferred to the refrigeration compartment 330, thereby improving the refrigeration efficiency of the refrigeration device 300.

[0114] The end cover 180 is used to cover the compressor, which can not only protect the compressor from external physical damage, but also help to improve the appearance of the refrigeration device 300 and enhance the visibility and aesthetics of the refrigeration device 300.

When the refrigeration assembly 200 is applied to the refrigeration equipment 300, it can be understood that the second side of the heat preservation plate faces the refrigeration compartment 330, and the first side and the second side are opposite sides. The design of the heat preservation plate enables the plate body 220 to not only have support and fixation, but also have a heat preservation effect, thereby improving the utilization efficiency of the space.

[0116] When the plate body 220 of the top plate assembly 100 is a thermal insulation layer, the thermal insulation layer and the thermal insulation board can effectively improve the thermal insulation effect. It can also be understood that the thermal insulation structure on the top of the refrigeration device 300 includes a thermal insulation layer and a thermal insulation board, and the thermal insulation layer is arranged in the top plate, and the thermal insulation board is arranged in the refrigeration assembly 200, which helps to simplify the manufacturing process of the top plate assembly 100 and the refrigeration assembly 200.
