Description

Technical Field

[0001] This invention relates to the field of electrical equipment technology, and in particular to a housing connection structure and an electrical housing and electrical appliances having the same structure. Background Technology

[0002] In recent years, dual-supply air conditioners, which can simultaneously provide heating and hot water, have become increasingly popular among consumers in northern China. These air conditioners utilize a compressor to compress high-temperature, high-pressure refrigerant to achieve both indoor heating and hot water heating. In this process, the high-temperature, high-pressure refrigerant flows sequentially through a hot water generator and the indoor unit for heat exchange. After liquefaction and heat release, the refrigerant flows into the condenser, where it absorbs heat from the air, vaporizes, and re-enters the compressor, completing one cycle. Because the hot water generator consists of components such as a shell-and-tube or plate heat exchanger and a water pump, it is relatively large and cannot be installed within existing air conditioner housings. Therefore, existing electrical housings need to be assembled or modified to accommodate these components.

[0003] In the internal structural layout design of the aforementioned air conditioners, the hot water generator is generally placed at the bottom of the unit, while the original outdoor unit components are placed at the top. If the casing used to house these components is composed of multiple assembled shells, gaps will appear at the joints between adjacent shells. These gaps will severely affect the waterproof performance of the casing, significantly increasing the possibility of rainwater entering the casing and causing short circuits in the internal electrical components. Redesigning the air conditioner casing would also significantly increase the manufacturing cost.

[0004] To solve the above problems, it is necessary to develop a new type of housing connection structure, as well as an electrical sheet metal housing with this structure and corresponding electrical equipment. Summary of the Invention

[0005] The purpose of this invention is to provide a housing connection structure and an electrical housing and electrical components having this structure, thereby solving the technical problem of water ingress at the joints of segmented housings in the prior art. The numerous technical effects of the preferred solutions among the many technical solutions provided by this invention are detailed below.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The housing connection structure provided by the present invention includes an upper connecting plate and a lower connecting plate, wherein the upper connecting plate is located above the lower connecting plate and a water-blocking and flow-guiding component is constructed at the connection between the two.

[0008] Water flowing into the water-blocking guide can be discharged through the outer side of the lower connecting plate.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] As a further improvement of the present invention, the water-blocking and guiding component includes a water-blocking component formed at the lower end of the upper connecting plate and a water-guiding component formed at the upper end of the lower connecting plate, wherein the upper end of the water-guiding component is located inside the water-blocking component.

[0011] As a further improvement of the present invention, the water guide includes an inclined surface pointing inward toward the water blocking element, at least a portion of the inclined surface being located below the water blocking element.

[0012] As a further improvement of the present invention, the included angle between the inclined surface and the lower connecting plate is 15 to 75°.

[0013] As a further improvement of the present invention, the water guiding component further includes a baffle located at the upper edge of the inclined surface, the upper edge of the baffle being higher than the upper edge of the water blocking component.

[0014] As a further improvement of the present invention, there is a gap between the water guiding element and the water blocking element.

[0015] As a further improvement of the present invention, the lower end of the upper connecting plate is bent inward to form the water-blocking element.

[0016] As a further improvement of the present invention, the included angle between the water-blocking component and the upper connecting plate bracket is 90°; and / or, the width of the water-blocking component is 1-25mm.

[0017] The present invention also provides an electrical appliance housing, comprising:

[0018] The housing connection structure described in any of the above items;

[0019] The chassis is located inside the upper connecting plate and the connection between the chassis and the upper connecting plate is higher than the water-blocking component. At least a portion of the chassis protrudes downward to form a sloping drainage component.

[0020] The present invention also provides an electrical appliance, including the electrical appliance housing described above.

[0021] Compared with the prior art, the preferred embodiment of the present invention provides the following beneficial effects:

[0022] Due to the aforementioned connection structure, the seam between the two upper and lower housings provides excellent waterproofing, effectively preventing rainwater from flowing into the housing through the connection. The inclined surface structure formed on the water guide allows water flowing to the connection structure to drain quickly. Simultaneously, this connection structure effectively improves the layout compatibility of the outer housing, increasing the commonality of housings for different devices and helping to reduce housing processing costs. Furthermore, the drainage component on the chassis guides the flow path of water flowing into the chassis, ensuring it flows along a designed path and exits, preventing water from spreading and entering live components, thus avoiding safety hazards. Moreover, this connection structure design does not affect the splicing and assembly of the upper and lower housings, offering the advantage of convenient assembly. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0029] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first," "second," and "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0031] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Example 1:

[0033] The present invention provides a housing connection structure, which includes an upper connecting plate 1, a lower connecting plate 2, and a water-blocking and flow-guiding component formed at the connection between the two.

[0034] It should be noted that the upper connecting plate 1 and the lower connecting plate 2 are arranged vertically. The water-blocking and guiding component can prevent water from flowing into the corresponding housing through the joint formed between the upper connecting plate 1 and the lower connecting plate 2. At the same time, it can also guide the water flowing into this area to be discharged along the outer side of the lower connecting plate 2. This effectively solves the problem that rainwater can easily flow into the housing from the joint, avoids damage to the electrical components located in the housing due to water ingress, and ensures that the equipment can be used safely.

[0035] In this embodiment, the water-blocking and guiding component comprises two parts: a water-blocking component 3 formed at the lower end of the upper connecting plate 1 and a water-guiding component 4 formed at the upper end of the lower connecting plate 2, wherein the upper end of the water-guiding component 4 is located inside the water-blocking component 3. Due to the obstruction of the water-blocking component 3, water flow is difficult to reach the upper edge of the water-guiding component 4, thus having the advantage of preventing water from flowing into the lower housing through the water-guiding component 4.

[0036] During processing, in order to avoid seams affecting the sealing effect of the connection structure, the water-blocking component 3 is integrally formed with the upper connecting plate 1. Similarly, the water-guiding component 4 is integrally formed with the lower connecting plate 2.

[0037] Both the water-blocking component 3 and the water-guiding component 4 mentioned above can be manufactured by sheet metal processing.

[0038] In order to drain water quickly and prevent rainwater from accumulating at the water guide 4, as an optional implementation, the water guide 4 includes an inclined surface 41 pointing inward toward the water blocking member 3, at least a portion of which is located below the water blocking member 3.

[0039] The bottom end of the inclined surface 41 is arranged outward, and rainwater falling on the inclined surface 41 can flow quickly downward through the inclined surface 41 to the outside of the lower connecting plate 2 and be discharged.

[0040] During processing, the aforementioned inclined surface 41 can be formed by bending the upper part of the lower connecting plate 2 inward. This inclined surface 41 can be a planar structure or a curved structure with a certain curvature. The specific shape of the inclined surface 41 can be adjusted according to actual needs, and no restrictions are imposed here.

[0041] It should be noted that the higher end of the inclined surface 41 can be located below the water-blocking component 3 or inside the water-blocking component 3. When the higher end of the inclined surface 41 is located below the water-blocking component 3, a baffle 42 structure located at the upper edge of the inclined surface 41 is also provided on the water-blocking component 3.

[0042] Specifically, the upper edge of the baffle 42 is higher than the upper edge of the water-blocking component 3. The water-guiding component 4, formed by the combination of the inclined surface 41 and the baffle 42, has a semi-U-shaped structure and has a good water-guiding effect.

[0043] The baffle 42 can be used in conjunction with the water-blocking component 3 to prevent rainwater from flowing into the corresponding housing.

[0044] Of course, when the higher end of the inclined surface 41 is located inside the water-blocking member 3, the above-mentioned baffle 42 structure can also be arranged on the upper edge of the inclined surface 41.

[0045] To ensure that the inclined surface 41 has a good drainage effect, in this embodiment, the inclined surface 41 is set as a planar structure, and the included angle between the inclined surface 41 and the lower connecting plate 2 is α. The value of α is in the range of 15 to 75°. This angle range can ensure that water will not stay at the inclined surface 41.

[0046] like Figure 1 As shown, the included angle α between the inclined surface 41 and the lower connecting plate 2 is 30°.

[0047] For ease of assembly and waterproofing purposes, as an optional implementation, a gap 43 exists between the water guide 4 and the water block 3. If the water guide 4 and the water block 3 are fitted together, rainwater may flow into the inside of the water block along the joint formed by the two, affecting the waterproofing effect of the connection structure; however, the gap 43 should not be too large, otherwise it will affect the insect-proofing effect of the casing.

[0048] Taking all factors into consideration, in this embodiment, the gap 43 formed between the water guide 4 and the water blocking component 3 is set to be no more than 2 mm.

[0049] If a baffle 42 is provided at the water guide 4, the gap 43 can be formed between the baffle 42 and the water blocking member 3, or between the inclined surface 41 and the water blocking member 3. If the water guide 4 only includes the inclined surface 41, the gap 43 is formed between the inclined surface 41 and the water blocking member 3.

[0050] The structure of the water-blocking component 3 described above is explained below:

[0051] The function of the water-blocking component 3 is to prevent rainwater from flowing into the inner side of the upper connecting plate 1. In this embodiment, the lower end of the upper connecting plate 1 is bent inward to form the water-blocking component 3, and the upper connecting plate 1 and the water-blocking component 3 are connected to form a bend structure.

[0052] In this embodiment, the angle between the water-blocking component 3 and the bracket of the upper connecting plate 1 is 90°, forming an L-shaped structure.

[0053] In order to enable the water-blocking component 3 to play a better blocking role, the width of the water-blocking component 3 is set to 1-25mm. At this time, the water-blocking component 3 is a strip structure with a certain width.

[0054] In addition to the above structure, the water-blocking element 3 can also be provided as a protrusion formed on the lower edge of the upper connecting plate 1, and the lower edge of the protrusion is a smooth curved surface.

[0055] The aforementioned protrusions can also provide some water-blocking effect.

[0056] It should be noted that the water guide 4 can be arranged horizontally or at an angle along the upper edge of the lower connecting plate 2. In this case, the water blocking component 3 is arranged in conjunction with the water guide 4 and the two are parallel to each other. The angled structure helps to guide rainwater to drain quickly.

[0057] Understandably, the aforementioned housing connection structure provides excellent water-blocking and water-guiding effects at the joint between the upper and lower housings, preventing rainwater from flowing into the housing through the gaps formed at the joint. This effectively solves the water ingress problem at the housing joint, improves the safety of electrically charged components located inside the housing, and also effectively prevents rainwater from accumulating at the joint. Furthermore, the aforementioned connection structure also offers the advantage of convenient assembly and splicing.

[0058] Example 2:

[0059] This embodiment provides an electrical housing, including the aforementioned housing connection structure and chassis 5.

[0060] Specifically, the chassis 5 is located inside the upper connecting plate 1 and the connection between the chassis 5 and the upper connecting plate 1 is higher than the water blocking member 3. At least a portion of the chassis 5 protrudes downward to form a slope-shaped drainage member 51.

[0061] The structure of the ramp-shaped drain element 51 is as follows: Figure 2 As shown, it can be used to guide the flow of water into the casing through gaps such as sheet metal seams, preventing rainwater from flowing into important components and causing safety hazards.

[0062] In this embodiment, the aforementioned drainage element 51 can be arranged along the length or width of the housing, or it can be arranged randomly or regularly in a dotted pattern relative to the surface of the chassis 5.

[0063] To better protect the equipment located inside the housing, as an optional implementation, the housing may also include a base plate located below the chassis 5 and connected to the lower connecting plate 2. The base plate is provided with at least one drainage hole, through which rainwater entering the area corresponding to the lower connecting plate 2 via the aforementioned drainage member 51 or other structures can be discharged.

[0064] Specifically, the aforementioned drainage component 51 can be arranged vertically and vertically corresponding to the drainage hole.

[0065] Understandably, compared to traditional housings, electrical housings using the aforementioned housing connection structure solve the problem of water leakage at the joints of spliced ​​housings, making it possible to arrange the housing in upper and lower sections. At the same time, this electrical housing can be flexibly spliced ​​and disassembled as needed, effectively improving the housing's versatility and helping to reduce processing costs.

[0066] Example 3:

[0067] This embodiment also provides an electrical appliance, including the electrical appliance housing described above.

[0068] Specifically, this appliance is a dual-supply air conditioner, and its overall structure is as follows: Figure 3As shown. The hot water generator is located below the fan, condenser, compressor, and related piping, and the two are separated by the aforementioned chassis 5.

[0069] To prevent rainwater from flowing into the live components of the hot water generator located below the chassis 5, a drainage component 51 is installed in a corresponding area of ​​the chassis 5 above the hot water generator. This drainage component 51 is located away from the live components of the hot water generator. Water entering the casing through sheet metal joints or welds will flow to a specific area under the guidance of the drainage component 51, preventing it from flowing randomly and greatly reducing the possibility of rainwater entering the live components, thus effectively improving the safety of the equipment.

[0070] Understandably, taking a dual-supply air conditioner as an example, compared with traditional dual-supply air conditioners, the dual-supply air conditioner using the above-mentioned casing connection structure not only solves the problem of water leakage at the joint of the spliced ​​casing, but also makes it possible to arrange the casing in upper and lower sections. At the same time, the above-mentioned connection structure can also separate the casing used to install the hot water generator from the casing used to install the traditional air conditioning components, making the layout of the outdoor unit with or without the hot water generator component highly compatible, while also effectively improving the standardization rate of components and greatly reducing the processing cost of the casing.

[0071] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
