Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and more particularly to a refrigeration device. Background Technology

[0002] In modern life, refrigeration equipment such as refrigerators and freezers have become indispensable household appliances for every family. As people's living standards continue to improve, users' demand for intelligent refrigeration equipment is also gradually increasing. Existing intelligent refrigeration equipment typically includes power modules with components such as communication, display, or sensing capabilities.

[0003] Currently, the electrical modules in existing refrigeration equipment not only have problems such as complex installation processes and high costs, but also lack consideration for waterproof design of the electrical modules. Summary of the Invention

[0004] The purpose of this invention is to provide an improved refrigeration preparation method.

[0005] This invention provides a refrigeration device, including a housing and a receiving slot for receiving a power module. The housing includes at least one wall, and the wall includes at least one exposed end. The receiving slot is disposed within the wall and has an inlet formed at the end. The power module includes a power component with wireless communication functionality. The receiving slot is configured to provide a receiving space suitable for accommodating the power component, and the power component is spaced a specific distance from the side wall of the receiving space.

[0006] The receiving slot defines a sufficiently large space to accommodate the electrical component, meaning the component is not in contact with the side walls of the space and is kept at a certain distance. This provides ample space for heat dissipation during operation, ensuring the component's normal functioning. Furthermore, this large space is free of other objects, especially metal objects, to prevent interference with the component's normal operation; for example, the component's communication signals will not be interfered with or blocked.

[0007] Optionally, the power module includes an embedded part embedded in the receiving groove, the embedded part being made of a non-metallic material, and the power component being disposed in the embedded part.

[0008] This embedded part can securely support the electrical components. And since the embedded part is made of a non-metallic material, will it not interfere with the normal operation of the electrical components, for example, will it not interfere with their communication signals?

[0009] Optionally, the embedding portion has a receiving cavity adapted to accommodate the electrical component, and the electrical component is spaced a specific distance from the sidewall of the receiving cavity.

[0010] The embedded part defines a sufficiently large receiving cavity to accommodate the electrical component. This provides ample space for heat dissipation around the component during operation, ensuring its normal functioning. Furthermore, this sufficiently large receiving cavity contains no other objects, especially no metal objects, thus preventing any interference with the component's normal operation. For example, the component's communication signals will not be interfered with or blocked.

[0011] Optionally, the power module includes a top cover located above the embedded portion, which covers the inlet.

[0012] Optionally, both the receiving groove and the top cover are made of non-metallic materials.

[0013] Optionally, the wall includes a heat insulation layer, and the receiving groove is at least partially located within the heat insulation layer.

[0014] Optionally, the cooling device does not include metal within a specific spatial range centered on the electrical component, in order to reduce or eliminate interference from metal on the wireless signals of the electrical component.

[0015] Optionally, the wall may further include a metal plate located on the wall surface of the insulation layer, the metal plate having a notch in the portion facing the electrical component.

[0016] Optionally, the orthographic projection of the electrical component onto the plane where the metal plate is located is located within the notch or coincides with the notch.

[0017] Another embodiment of the present invention provides a refrigeration device including a housing and a receiving slot for receiving an electrical module. The housing includes at least one wall, the wall including at least one exposed end. The receiving slot is disposed within the wall and has an inlet formed at the end. The end has a guide channel in the portion of its location around the inlet to guide liquid around the inlet to a location away from the inlet.

[0018] Optionally, the guide channel includes a guide section and a drain section, the guide section is arranged around the inlet, and the drain section is connected to the guide section and extends to the outside of the end.

[0019] Alternatively, along the direction from the guide section to the discharge section, the guide channel has an inner bottom wall that decreases continuously in the direction of gravity.

[0020] Optionally, the plane containing the inner bottom wall forms a predetermined angle with the plane containing the end face of the end.

[0021] Optionally, the wall is provided with a liquid collection section near its end, which is connected to the liquid discharge section.

[0022] Optionally, the power module includes a power element with wireless communication function, the embedded part is made of non-metallic material and has a receiving cavity suitable for accommodating the power element, and a specific distance is spaced between the power element and the side wall of the receiving cavity.

[0023] Optionally, the power module includes a top cover located above the embedded portion, which closes the inlet.

[0024] Optionally, the end is provided with a first recess, which is adapted to accommodate the top cover.

[0025] Optionally, the guide section is located within the first recess and is covered under the top cover.

[0026] Optionally, the guide channel further includes a second recess disposed within the first recess and sinking relative to the first recess; the second recess is connected to the guide section and is adapted to guide liquid through the guide section to the drain section, or directly to the drain section.

[0027] Optionally, the wall includes at least one side clip, with the end formed by the side clip.

[0028] Optionally, the side card is located at the upper end of the wall.

[0029] Optionally, the wall includes an insulation layer, and the receiving groove is at least partially located within the insulation layer.

[0030] Optionally, the power module includes power components with wireless communication capabilities, and the refrigeration equipment does not include metal within a specific elliptical space centered on the power components, in order to reduce or eliminate interference from metal on the wireless signals of the power components.

[0031] Compared with the prior art, the technical solution of the present invention has beneficial effects. For example, the end is provided with a guide channel in the part around the inlet of the receiving tank, which can guide the liquid around the inlet to a position away from the inlet, so as to avoid the electrical module installed in the receiving tank being corroded by the liquid.

[0032] For example, the receiving groove can extend not only in a plane perpendicular to the wall thickness direction, but also along the length of the wall to reduce the thickness of the insulation layer occupied by the receiving groove, thereby reducing the risk of condensation on the electrical components in the electrical module.

[0033] For example, the wall also has a liquid collection section near its end. The liquid collection section is located below the end and communicates with the drainage section, and it is used to collect the liquid that flows out through the guide channel. The liquid collected in the liquid collection section can evaporate naturally to dryness.

[0034] For example, when a wall is formed through a door, the metal plate of the door has a notch in the part facing the electrical component, so that there is no or little metal material around the electrical component, thereby improving and enhancing the wireless signal of the electrical module.

[0045] Existing intelligent refrigeration equipment usually has a power supply module, but it often lacks consideration for waterproof design of the power supply module.

[0046] The present invention provides an improved refrigeration device. The refrigeration device includes a housing and a receiving tank for receiving electrical modules. The housing includes at least one wall, and the wall includes at least one exposed end. The receiving tank is disposed within the wall and has an inlet formed at the end. The end has a guide channel on its periphery of the inlet, which can guide liquid around the inlet to a position away from the inlet, thereby preventing the electrical modules disposed in the receiving tank from being corroded by the liquid.

[0047] To make the objectives, features, and beneficial effects of the embodiments of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0048] Figure 1 This is a schematic diagram of the structure of the refrigeration equipment in an embodiment of the present invention. The schematic diagram is a perspective view of the receiving tank portion.

[0049] like Figure 1 As shown, the refrigeration equipment 10 includes a housing 100 and a power receiving module (…). Figure 1 The receiving tank 300 (not shown in the image).

[0050] In some specific examples, the refrigeration device 10 may be a refrigerator or freezer, or other appliance suitable for storing items and keeping them at low temperatures.

[0051] Specifically, the refrigeration equipment 10 may include a cabinet 100, which may further include a cabinet body and a door. The cabinet body is used to form a chamber suitable for storing items and having an access opening; the door is connected to the cabinet body and is adapted to move relative to the cabinet body to open or close the access opening of the chamber.

[0052] The enclosure 100 also includes at least one wall 200.

[0053] Figure 2 This is a schematic diagram of the wall structure in an embodiment of the present invention.

[0054] Reference Figure 1 and Figure 2 The wall 200 includes at least one exposed end 210. A receiving groove 300 is disposed within the wall 200 and has an inlet 310 formed at the end 210. The power module 20 can be disposed within the receiving groove 300 through the inlet 310.

[0055] In some specific examples, the wall 200 may be formed by the housing body. It should be noted that the wall 200 formed by the housing body should include at least one exposed end 210 to facilitate the placement of the receiving groove 300 and its inlet 310.

[0056] In other preferred embodiments, the wall 200 may also be formed by a door. Doors typically include at least one exposed end 210. For example, a door mounted on one side of the enclosure body may include an upper end, a lower end, and a side end.

[0057] Reference Figure 1 The refrigeration device 10 includes two opposing doors, through which a wall 200 is formed, and has an exposed upper end, lower end, and side end. A receiving slot 300 is located on the upper part of the wall 200 and has an inlet 310 formed at the upper end.

[0058] In other specific examples, the receiving groove 300 may also be located on the side or lower part of the wall 200 and have an inlet 310 formed at the side or lower end.

[0059] However, in response to Figure 1 As shown in the example, placing the inlet 310 of the receiving groove 300 at the side end of the wall 200 would affect the aesthetics of the door; placing the inlet of the receiving groove 300 at the lower end of the wall 200 would make the use of the receiving groove 300 inconvenient. Therefore, placing the receiving groove 300 at the upper part of the wall 200 and having an inlet 310 formed at the upper end can be considered a better example.

[0060] Figure 3 This is a schematic diagram of the power module in an embodiment of the present invention. The embedded part of the schematic diagram is shown in perspective.

[0061] like Figure 3 As shown, the power module 20 may include an insert portion 21 and a top cover 22 located above the insert portion 21. The power module 20 is inserted into the receiving groove 300 through the insert portion 21, and the inlet 310 is covered by the top cover 22. The insert portion 21, the top cover 22, and the receiving groove 300 are preferably made of non-metallic materials. The power module 20 also includes a power component 23, which is disposed in the insert portion 21 and enters and is received in the receiving space constructed by the receiving groove 300.

[0062] In some specific examples, the receiving groove 300 has an inner contour that matches the outer contour of the insert 21 so that the insert 21 can be tightly embedded in the receiving groove 300.

[0063] In other specific examples, the insert 21 may be integrally formed with the top cover 22, and both may be made of non-metallic materials, such as plastic.

[0064] The interior of the embedded part 21 also has a receiving cavity suitable for accommodating the electrical component 23, so as to better fix and support the electrical component 23 in the receiving groove 300.

[0065] In some specific examples, the electrical component 23 may include one or more of the following: communication components, display components, or sensing components.

[0066] Figure 4 This is a partial schematic diagram of the wall in an embodiment of the present invention.

[0067] like Figure 4 As shown, the end portion 210 is provided with a first recess 211 suitable for receiving the top cover 22.

[0068] In some specific examples, the first recess 211 has dimensions and structure that match the top cover 22 so as to better accommodate the top cover 22 and make the top surface of the top cover 22 flush with the top surface of the end 210.

[0069] In some other specific examples, the top cover 22 may also be fixedly connected to the wall 200.

[0070] Continue to refer to Figure 3 and Figure 4 Screws 24 can be provided on the top cover 22, and threaded holes 212 located in the first recess 211 are opened in the wall 200 and its end 210 to cooperate with the screws 24. The top cover 22 is fixedly installed on the end 210 of the wall 200 by the threaded connection between the screws 24 and the threaded holes 212.

[0071] Continue to refer to Figure 4 The first recess 211 may also be provided with a second recess 213 suitable for accommodating the recessed portion of the screw 24, and the top end of the threaded hole 212 is located in the second recess 213. In this way, the screw 24 can be better connected in the threaded hole 212, and the top surface of the screw 24 is flush with the top surface of the end 210.

[0072] Continue to refer to Figure 4 The end 210 is also provided with a flow guide 220 in the part located around the inlet 310. The flow guide 220 can guide the liquid around the inlet 310 to a position away from the inlet 310, so as to avoid the electrical module 20 installed in the receiving tank 300 from being corroded by the liquid.

[0073] Figure 5 This is a partial schematic diagram of the end portion in an embodiment of the present invention.

[0074] Reference Figure 4 and Figure 5 The guide channel 220 includes a guide section 221 and a drain section 222. The guide section 221 is arranged around the outer periphery of the inlet 310, and the drain section 222 communicates with the guide section 221 and extends to the end face 214 of the end 210.

[0075] Figure 6 This is a partial side sectional view of the wall in an embodiment of the present invention.

[0076] Combination Figure 5 and Figure 6Along the direction from the guide section 221 to the discharge section 222, the guide channel 220 has an inner bottom wall that continuously decreases in the direction of gravity G. The inner bottom wall is formed on the end face of the bottom of the guide channel 220, allowing liquid flowing into the guide channel 220 to flow along the inner bottom wall within the guide channel 220. In this way, liquid located around the inlet 310 can flow along the guide section 221 to the discharge section 222 under its own gravity, and then flow out of the end face 214 of the end 210.

[0077] In the technical solution provided in the embodiments of the present invention, the aforementioned gravity direction G is the vertically downward direction.

[0078] Reference Figure 6 The plane containing the end face 214 of the end 210 is marked as S1, and the plane containing the inner bottom wall of the guide channel 220 is marked as S2, so that a predetermined angle can be formed between S1 and S2.

[0079] In some specific examples, the plane S1 containing the end face 214 of end 210 can be parallel to the horizontal plane. This allows a predetermined angle to be formed between the plane S2 containing the inner bottom wall and the horizontal plane. This angle allows the inner bottom wall of the guide channel 220 to have a certain slope, facilitating the diversion of liquid around the inlet 310 through the guide channel 220 to a position away from the inlet 310, thereby preventing the electrical module 20 from being corroded by the liquid.

[0080] Continue to refer to Figure 4 and Figure 5 The guide section 221 is located inside the first recess 211 and can be covered under the top cover 22. In this way, the liquid located in the first recess 211 can also flow along the guide section 221 to the drain section 222 under its own gravity, and flow to the end face 214 of the end 210.

[0081] Figure 7 This is a schematic diagram of the flow guiding groove in an embodiment of the present invention.

[0082] Reference Figure 4 , Figure 5 and Figure 7 The second recess 213 can communicate with the guide section 221. The guide channel 220 may also include a second recess 213 that communicates with the guide section 221. The second recess 213 can guide the liquid located in the first recess 211 through the guide section 221 to the drain section 222, or directly to the drain section 222.

[0083] exist Figure 4 , Figure 5 and Figure 7In the example shown, the first recess 211 is provided with two second recesses 213. The two second recesses 213 are located on both sides of the first recess 211. One second recess 213 is connected to the side of the guide section 221 away from the drain section 222; the other second recess 213 is connected to both the side of the guide section 221 near the drain section 222 and the drain section 222, that is, the guide section 221 and the drain section 222 are connected through the second recess 213.

[0084] In order to facilitate the smooth discharge of liquid from the end face 214 of the end 210, the guide channel 220 has an inner bottom wall that is continuously lower in the direction of gravity, along the direction in which the second recess 213 communicates with the side of the guide section 221 away from the discharge section 222, the guide section 221, the second recess 213 communicates with the side of the guide section 221 close to the discharge section 222, and the discharge section 222.

[0085] Similarly, a predetermined angle is formed between the inner bottom wall and the horizontal plane so that the inner bottom wall has a certain slope, so that the liquid around the inlet 310 can be guided through the guide channel 220 to a position away from the inlet 310, thereby avoiding the electrical module 20 from being corroded by the liquid.

[0086] Continue to refer to Figure 4 The wall 200 is also provided with a liquid collection section 230 near its end 210. The liquid collection section 230 is located below the end 210 and communicates with the drainage section 222, and is used to collect the liquid that flows out through the guide channel 220.

[0087] Since the amount of liquid around the inlet 310 of the receiving tank 300 is small, the liquid collected at the liquid collection section 230 through the guide channel 220 can evaporate naturally to dryness.

[0088] Figure 8 This is an exploded view of the wall in an embodiment of the present invention.

[0089] exist Figure 8 In the example shown, wall 200 is formed through the door of refrigeration device 10.

[0090] Figure 8 The diagram illustrates four directions: up, down, front, and back. These directions are determined based on the view of the door facing the user under normal usage conditions. "Front" represents the direction of the door closer to the user, "back" represents the direction of the door farther from the user, "up" represents the direction of the top of the door, and "down" represents the direction of the bottom of the door. It should be understood that other perspectives of the door will also present corresponding up, down, front, and back directions. Figure 8The directions of up, down, front, and back shown in the illustrations are only for the purpose of describing the technical solutions of the embodiments of the present invention, and do not constitute a restrictive interpretation of these solutions.

[0091] like Figure 8 As shown, the wall 200 formed by the door may also include a heat insulation layer. Figure 8 (not shown in the image), metal plate 240 and door liner 250.

[0092] The insulation layer is located inside the end 210 and together with the end 210 defines the receiving space of the receiving groove 300. At least a portion of the receiving groove 300 is located within the insulation layer, and the inner wall of the end 210 and the insulation layer form a partial boundary of the receiving space.

[0093] In the technical solution provided in the embodiments of the present invention, the inner side of the aforementioned end 210 is the side of the end 210 facing the interior of the door body.

[0094] In some specific examples, the receiving groove 300 may extend in a plane perpendicular to the thickness direction of the wall 200. Furthermore, the receiving groove 300 may also extend along the length direction of the wall 200. This reduces the thickness of the insulation layer occupied by the receiving groove 300, thereby reducing the risk of condensation on the electrical components in the electrical module 20.

[0095] exist Figure 8 In the example shown, the thickness direction of the aforementioned wall 200 is the front-to-back direction of the wall 200, and the length direction of the aforementioned wall 200 is the up-to-down direction of the wall 200.

[0096] The metal plate 240 is located inside the end 210 and in front of the heat insulation layer. In one or more preferred embodiments, the metal plate 240 also has a notch 241 on the portion facing the power component 23. This allows for a low or no metal material around the power component 23, thereby improving and enhancing the wireless signal of the power module 20.

[0097] The wall 200 may also include a front panel 260 disposed inside the end 210 and attached to the front of the metal plate 240. In some specific examples, the front panel 260 may also be used to form a partial boundary of the accommodating space.

[0098] The door liner 250 is located inside the end 210, behind the insulation layer. In some specific examples, the door liner 250 may also be used to form a partial boundary of the accommodating space.

[0099] The wall 200 may also include at least one side clip. The side clip may include at least one of an upper side clip 271, a side clip 272, and a lower side clip 273. The end 210 may be formed by the side clip, with the heat insulation layer and the metal plate 240 located inside the side clip.

[0100] Reference Figure 8 The wall 200 includes an upper clip 271, a side clip 272, and a lower clip 273, all of which are made of non-metallic materials. The upper end of the receiving groove 300 is formed by the upper clip 271.

[0101] In some specific examples, the plane containing the end face of the upper card 271 can be parallel to the horizontal plane. However, considering the limited thickness of the upper card 271, the angle between the plane containing the end face of the upper card 271 and the plane containing the inner bottom wall of the guide channel 220 can be limited to a range of greater than or equal to 1° and less than or equal to 3°, so that the inner bottom wall of the guide channel 220 has a certain slope, so as to guide the liquid around the inlet 310 through the guide channel 220 to a position away from the inlet 310.

[0102] In the technical solutions provided in the embodiments of the present invention, the power module 20 may include a power component 23 with wireless communication function. In some specific examples, the power component 23 may be a printed circuit board (PCB) with an integrated wireless communication antenna.

[0103] To improve the wireless signal of the power supply component 23, considerations can be given to both the spatial range closer to the power supply component 23 and the spatial range farther from the power supply component 23. For the spatial range closer to the power supply component 23, the power supply component 23 should be protected from interference by any objects within that range. For the spatial range farther from the power supply component 23, the power supply component 23 should be protected from interference by any metallic objects within that range.

[0104] To solve the above problems, new designs can be made from both the power module 20 and the wall 200.

[0105] Figure 9 This is another partial side sectional view of the wall in an embodiment of the present invention.

[0106] like Figure 9 As shown, the wall 200 can be formed through the door of the refrigeration equipment 10, which includes a front panel 260, a metal plate 240, a heat insulation layer 270, and a door liner 250 arranged in sequence.

[0107] A receiving groove 300 is provided within the heat insulation layer 270, and the receiving groove 300 is made of non-metallic material. A power module 20 is disposed within the receiving groove 300. The power module 20 includes an embedding part 21. The embedding part 21 has a receiving cavity 25 suitable for accommodating an electrical component 23.

[0108] In some specific examples, the embedded part 21 of the power module 20 is made of non-metallic material, and the sidewall of the receiving cavity 25 does not contact the power component 23 and maintains a specific distance.

[0109] The specific distance can typically be in the millimeter range, and it is related to the performance and parameters of the wireless communication antenna in the power supply element 23. The specific value can be set according to the specific performance and parameters of the wireless communication antenna in the power supply element 23.

[0110] In this way, by setting a specific distance between the power-consuming element 23 and the sidewall of the receiving cavity 25, the wireless signal of the power-consuming element 23 can be ensured to be unaffected by objects (e.g., the non-metallic embedded part 21) in the space close to it, thereby improving the wireless signal strength of the power-consuming element 23.

[0111] Furthermore, it is also necessary to ensure that the wireless signal of the power component 23 is not interfered with by metal objects in a spatial range at a greater distance from it.

[0112] To address this issue, the cooling device 10 can be made to exclude metal from a specific elliptical space A centered on the power-consuming element 23, thereby reducing or eliminating interference from metal on the wireless signal of the power-consuming element 23.

[0113] The specific elliptic space range is related to the performance and parameters of the wireless communication antenna in the power supply element 23, and the specific value can be set according to the specific performance and parameters of the wireless communication antenna in the power supply element 23.

[0114] In some specific examples, the metal can be excluded from a specific elliptical space A centered on the electrical component 23 by limiting the metal to be excluded from a specific space B in front of and behind the receiving tank 300.

[0115] Reference Figure 9 The specific space range B in front of and behind the accommodating tank 300 is greater than or equal to the specific elliptical space range A centered on the electrical component 23.

[0116] In some specific examples, the receiving slot 300 is located inside the insulation layer 270, behind which is the door liner 250, and behind the door liner 250 is the chamber of the refrigeration device 10.

[0117] Typically, the chamber, door liner 250, and insulation layer 270 of the refrigeration device 10 do not contain metal. As a result, the area behind the receiving groove 300 located in the insulation layer 270 does not contain metal, and consequently, the area behind the electrical component 23 located in the receiving groove 300 also does not contain metal. This allows the wireless signal of the electrical component 23 to be free from interference from metal behind it.

[0118] Reference Figure 8 and Figure 9 The metal plate 240 may have a notch 241 on the part of it facing the electrical component 23.

[0119] In the technical solution provided in the embodiments of the present invention, the size of the notch 241 can be neither too small nor too large. If it is too small, the metal plate 240 will cause significant interference to the wireless signal of the power component 23. If it is too large, the strength of the metal plate 240 will be weakened, affecting its function as a supporting structure.

[0120] Figure 10 This is a schematic diagram of the projection of the electrical components in the plane where the metal plate is located, according to an embodiment of the present invention.

[0121] like Figure 10 As shown, in some preferred specific examples, the orthographic projection 23' of the electrical component 23 in the plane S where the metal plate 240 is located can be located within the notch 241.

[0122] In some other preferred specific examples, the orthographic projection 23' of the electrical component 23 in the plane S in which the metal plate 240 is located can also coincide with the notch 241.

[0123] In this way, the wireless signal of the power-consuming component 23 can be protected from interference by metal in front of it.

[0124] Although a front panel 260 may be provided in front of the metal plate 240, the front panel 260 is usually not made of metal. For example, it can usually be made of glass. Therefore, the presence of the front panel 260 will not cause significant interference to the wireless signal of the power supply component 23.

[0125] In summary, by employing the technical solution provided in the embodiments of the present invention, metal can be excluded from the specific spatial range B in front of and behind the receiving groove 300. Furthermore, since the specific spatial range B in front of and behind the receiving groove 300 is greater than or equal to the specific elliptical spatial range A centered on the power-consuming element 23, it can be ensured that the wireless signal of the power-consuming element 23 is not interfered with by metal objects in a spatial range at a greater distance from it.

[0126] Although specific embodiments have been described above, these embodiments are not intended to limit the scope of the invention, even when only a single embodiment is described with respect to a particular feature. The feature examples provided in this disclosure are intended to be illustrative and not limiting, unless otherwise stated. In practice, one or more technical features of the dependent claims may be combined with the technical features of the independent claims as needed and where technically feasible, and the technical features from the respective independent claims may be combined in any suitable manner rather than solely by the specific combinations listed in the claims.

[0127] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
