[0039] In the related art, a kitchen air conditioner generally has a cold zone and a hot zone, and the hot zone and the cold zone are designed to effectively manage heat exchange, thereby realizing the functions of refrigeration and heating, wherein an electric control box is arranged in the cold zone. However, the electric control box is likely to affect the sealing performance of the hot zone during disassembly and assembly, and the sealing effect of the hot zone is poor.

[0040] To solve the above technical problems, an embodiment of the present application provides a kitchen air conditioner, which comprises a sealing structure; a sealing plate cover is arranged at an opening and connected with a shell and a partition plate to form at least partial sealing of a hot zone; and a connecting part of an electric control box is arranged at a side edge of a front side of the sealing plate. In this way, the electric control box does not affect the assembly of the sealing plate during disassembly and assembly, thereby avoiding affecting the sealing of the hot zone and maximizing the sealing effect of the hot zone; at the same time, the arrangement of the sealing structure can effectively prevent the leakage of gas or liquid in the hot zone to the cold zone, thereby reducing potential safety hazards.

[0041] In order to make the purposes, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0042] Referring to Figures 1 to 3 The embodiments of the present application provide a kitchen air conditioner, which comprises a shell 100, a partition plate 210, an electric control box 300 and a sealing structure, and the sealing structure has at least one sealing plate 220.

[0043] In the embodiments of the present application, the material of the shell 100 is not limited. For example, the shell 100 can be made of stainless steel, which has good corrosion resistance and heat resistance, and is easy to clean and maintain; or the shell 100 can be made of aluminum alloy, which is light and has good corrosion resistance and good heat conduction performance, which can help heat dissipation. The present embodiment is not limited in this regard.

[0044] For example, the shell 100 comprises a front panel 110, a top panel 160 and a plurality of side panels connected head to tail.

[0045] Among them, the number of sealing plates 220 is not limited, for example, the number of sealing plates 220 can include one, two or more. The present embodiment is not limited in this regard, and can be set according to actual needs.

[0046] In the embodiments of the present application, referring to Figure 2 The shell 100 has a cavity, the partition plate 210 divides the cavity into a cold zone 140 and a hot zone 150 arranged transversely side by side, and the shell 100 has an opening 170 toward the front side of the kitchen air conditioner at least in the hot zone 150.

[0047] In the embodiments of the present application, the material of the partition plate 210 is not limited. For example, the partition plate 210 can be made of heat-resistant material, such as aluminum or stainless steel, which has good heat resistance and heat conductivity, and can effectively withstand the high-temperature environment of the hot zone 150; or the partition plate 210 can be made of heat-insulating material, such as polyurethane foam, which has good heat-insulating performance and can effectively reduce heat transfer. The present embodiment is not limited in this regard.

[0048] In the embodiments of the present application, the shape of the partition plate 210 is not limited. For example, referring to Figure 3 The partition plate 210 can be a flat plate shape, which is easy to manufacture and install; or the partition plate 210 can be arc-shaped or curved, and the present embodiment is not limited in this regard.

[0049] In this way, the partition plate 210 divides the cavity into the cold zone 140 and the hot zone 150, effectively isolates the two, reduces the heat transfer from the hot zone 150 to the cold zone 140, and improves the thermal management efficiency of the system.

[0050] In the embodiment of the present application, the electric control box 300 is arranged in the cold zone 140, which helps to ensure that the electric control box 300 is away from the high-temperature environment of the hot zone 150, prevents overheating from damaging the electronic components in the electric control box 300, and improves the reliability and service life of the electric control box 300.

[0051] In the embodiment of the present application, the sealing plate 220 is arranged on the opening 170 and connected with the shell 100 and the partition plate 210 to at least form a partial sealing of the hot zone 150. In this way, by partially sealing the hot zone 150, unnecessary heat loss is reduced, and the overall energy efficiency of the kitchen air conditioner is improved.

[0052] In the embodiment of the present application, in order to avoid the electric control box 300 affecting the assembly of the sealing plate 220 and the sealing performance of the hot zone 150 during disassembly, the electric control box 300 can be provided with a connecting portion at least on the side close to the partition plate 210, and the edge of the sealing plate 220 close to the partition plate 210 is connected with the partition plate 210, and the connecting portion is arranged on the edge of the front side of the sealing plate 220.

[0053] In the embodiment of the present application, the specific structure of the connecting portion is not limited. For example, the connecting portion can be a flange, or the connecting portion can be a connecting bracket. The present embodiment does not limit this.

[0054] In the embodiment of the present application, the connecting manner of the connecting portion and the electric control box 300 is not limited. For example, the connecting portion and the electric control box 300 can be an integral piece, or the connecting portion and the electric control box 300 can be connected by screws. The present embodiment does not limit this.

[0055] It should be noted that the connecting portion is arranged on the edge of the front side of the sealing plate 220. It can be understood that from the front view of the kitchen air conditioner, the connecting portion is located on the side closer to the front panel 110 relative to the sealing plate 220, that is, the connecting portion is located on the side closer to the user of the sealing plate 220.

[0056] In this way, when the electric control box 300 is disassembled, the front panel 110 can be disassembled first, and then the electric control box 300 is disassembled from the front side of the kitchen air conditioner, so as not to interfere with and affect the assembly of the sealing plate 220, and further avoid affecting the sealing of the hot zone 150, thereby maximizing the sealing effect of the hot zone 150.

[0057] In one implementation that can be implemented, with reference to Figure 4And Figure 5 As shown in the figure, the electric control box 300 can include a box body 310 and a flange 320, the flange 320 is a connecting part, and the flange 320 is located at the circumferential side of the box body 310. Among them, the box body 310 can be installed with circuit boards and other electrical components.

[0058] Among them, the flange 320 can be connected to the circumferential side of the box body 310 by screws. It can be understood that the circumferential side refers to the side area of the box body 310, that is, the flange 320 is arranged along the outer edge or side of the box body 310, rather than at the top or bottom of the electric control box 300.

[0059] In this way, the flange 320 as a connecting part provides an additional fixing point, making the electric control box 300 more stable during installation, reducing loosening or displacement caused by vibration or external force; moreover, the close engagement of the flange 320 with the box body 310 forms an effective seal, which can also prevent dust, moisture or other contaminants from entering the interior of the electric control box 300, thereby improving the safety performance of the electric control box 300. At the same time, it can increase the contact area with the sealing plate 220, improve the connection stability of the electric control box 300 and the sealing plate 220, and enhance the overall sealing performance.

[0060] In an implementable embodiment, referring to Figure 2 As shown in the figure, the shell 100 can include a first side plate 120, and the part of the flange 320 away from the sealing plate 220 is connected with the first side plate 120.

[0061] For example, the first side plate 120 can be a plate located on the left side in the transverse direction.

[0062] Among them, the connection mode of the flange 320 and the first side plate 120 is not limited. For example, the flange 320 and the first side plate 120 can be connected by screws, which is not limited in this embodiment.

[0063] In this way, in the transverse direction, one side of the flange 320 is connected with the first side plate 120, and the other side of the flange 320 is connected with the sealing plate 220 to form a multi-point fixing structure, which helps to improve the connection strength of the flange 320 and the sealing plate 220, and further ensures the installation stability of the electric control box 300.

[0064] In an implementable embodiment, referring to Figure 4 As shown in the figure, the sealing plate 220 can include a plate body 221 and an extension edge 222, the extension edge 222 is located at the circumferential side of the plate body 221, and the flange 320 is pressed against the edge of the extension edge 222 facing the front side of the kitchen air conditioner.

[0065] The extension edge 222 can be connected to the peripheral side of the plate body 221 by screws, or the extension edge 222 and the plate body 221 can be an integral piece, which is not limited in the embodiment. It can be understood that the extension edge 222 is arranged along the outer edge or side of the plate body 221, rather than at the top or bottom of the sealing plate 220.

[0066] In this way, the extension edge 222 can further provide an additional sealing contact surface, further enhancing the sealing effect of the sealing plate 220 on the hot area 150; at the same time, the folded edge 320 is pressed against the extension edge 222, increasing the tightness and stability of the connection.

[0067] In an implementable embodiment, referring to Figure 2 The housing 100 includes a second side plate 130 opposite the first side plate 120, and the part of the extension edge 222 facing away from the electric control box 300 is connected to the second side plate 130.

[0068] For example, the second side plate 130 can be a plate located on the right side in the transverse direction.

[0069] The connection mode of the extension edge 222 and the second side plate 130 is not limited. For example, the extension edge 222 and the second side plate 130 can be connected by screws, which is not limited in the embodiment.

[0070] In this way, in the transverse direction, one side of the extension edge 222 is connected to the second side plate 130, and the other side of the extension edge 222 is connected to the folded edge 320 to form a multi-point fixing structure, which helps to improve the connection strength of the folded edge 320 and the sealing plate 220, and further ensures the installation stability of the sealing plate 220.

[0071] In an implementable embodiment, referring to Figure 2 The partition plate 210 has a side edge 211 facing the front side of the kitchen air conditioner, and the extension edge 222 is connected to the side edge 211.

[0072] It should be noted that the side edge 211 of the partition plate 210 refers to, from the front view of the kitchen air conditioner, the side of the connection part closer to the front panel 110 relative to the sealing plate 220, and the side edge 211 of the partition plate 210 is located closer to the cavity relative to the sealing plate 220.

[0073] In this way, the connection of the extension edge 222 and the side edge 211 of the partition plate 210 provides a continuous sealing path, ensuring effective isolation between the cold area 140 and the hot area 150.

[0074] In an implementable embodiment, referring to Figure 2As shown, the first connecting hole 330 can be arranged on the turn-up 320, the second connecting hole 223 can be arranged on the extension edge 222, and the third connecting hole 212 can be arranged on the side edge 211. The fastener is sequentially arranged in the first connecting hole 330, the second connecting hole 223, and the third connecting hole 212 to connect the turn-up 320, the extension edge 222, and the partition plate 210.

[0075] For example, the fastener can be a screw. In addition, the number of the first connecting hole 330, the second connecting hole 223, and the third connecting hole 212 is not limited, and can be set according to actual needs.
