The technical scheme of the utility model is specifically described below with reference to the accompanying drawings.
Example 1:
the utility model provides a shell connecting structure which comprises an upper connecting plate 1, a lower connecting plate 2 and a water-blocking guide piece formed at the connecting part of the upper connecting plate and the lower connecting plate.
It should be noted that the upper connecting plate 1 and the lower connecting plate 2 are arranged up and down, wherein the water blocking guide piece can prevent water from flowing into the corresponding casing through the seam formed between the upper connecting plate 1 and the lower connecting plate 2, and meanwhile, the water flowing into the water blocking guide piece can be guided to be discharged along the outer side surface of the lower connecting plate 2, so that the problem that rainwater easily flows into the casing from the seam is effectively solved, the charged components in the casing are prevented from being damaged due to water inflow, and the safe use of the equipment is ensured.
In this embodiment, the water blocking and guiding member includes two parts, namely a water blocking member 3 formed at the lower end of the upper connecting plate 1 and a water guiding member 4 formed at the upper end of the lower connecting plate 2, wherein the upper end of the water guiding member 4 is located inside the water blocking member 3. Under the blocking of the water blocking member 3, the water hardly flows to the upper edge of the water guiding member 4, and there is an advantage in that the water is blocked from flowing through the water guiding member 4 into the lower housing.
In order to avoid the sealing effect of the connecting structure affected by the seam, the water blocking piece 3 and the upper connecting plate 1 are integrally formed, and the water guiding piece 4 and the lower connecting plate 2 are integrally formed in the same way.
The water blocking member 3 and the water guiding member 4 can be manufactured by sheet metal.
For rapid drainage, rainwater is avoided from accumulating at the water guide 4, as an alternative embodiment the water guide 4 comprises an inclined surface 41 pointing in the direction of the inner side of the water blocking member 3, at least part of the inclined surface 41 being located below the water blocking member 3.
The bottom end of the inclined surface 41 is disposed outwardly, and rainwater falling on the inclined surface 41 can rapidly flow downward to the outside of the lower connecting plate 2 via the inclined surface 41 and be discharged.
In the machining, the inclined surface 41 may be formed by bending the upper end portion of the lower connecting plate 2 inward. The inclined surface 41 may have a planar structure or a curved structure having a certain curvature. The specific shape of the inclined surface 41 may be adjusted according to actual needs, and is not limited thereto.
It should be noted that the higher end of the inclined surface 41 may be located below the water blocking member 3 or may be located inside the water blocking member 3. When the higher end of the inclined surface 41 is located below the water blocking member 3, a baffle 42 structure located at the upper edge of the inclined surface 41 is further disposed on the water blocking member 3.
Specifically, the upper edge of the baffle 42 is higher than the upper edge of the water blocking member 3. The water guide member 4 formed by combining the inclined surface 41 and the baffle plate 42 is of a semi-U-shaped structure, and has a good water guide effect.
The baffle 42 may be adapted to cooperate with the water blocking member 3 to block the flow of rainwater into the respective housing.
Of course, when the higher end of the inclined surface 41 is located inside the water blocking member 3, the above-described baffle 42 structure may be disposed at the upper edge of the inclined surface 41.
In order to ensure that the inclined surface 41 has a good water draining effect, in this embodiment, the inclined surface 41 is provided with a planar structure, the included angle between the inclined surface 41 and the lower connecting plate 2 is α, and the value of α is 15-75 °, which can ensure that water does not stay at the inclined surface 41.
As shown in fig. 1, the angle α between the inclined surface 41 and the lower connecting plate 2 is 30 °.
For ease of assembly and water-repellent effect, as an alternative embodiment, a gap 43 is present between the water guide 4 and the water blocking member 3. If the water guide member 4 and the water blocking member 3 are attached, rainwater may flow into the inner side of the water blocking member along a joint gap formed by attaching the two members, so as to affect the waterproof effect of the connection structure; however, the gap 43 should not be too large, which would affect the insect-repellent effect of the casing.
In the present embodiment, the gap 43 formed between the water guide 4 and the water blocking member 3 is set to not more than 2mm.
If the baffle 42 is provided at the water guide 4, the gap 43 may 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 includes only the inclined surface 41, the gap 43 is formed between the inclined surface 41 and the water blocking member 3.
The structure of the water blocking member 3 is described below:
the function of the water blocking member 3 is to block the flow of rainwater into the inside of the upper connecting plate 1. In this embodiment, the lower end of the upper connecting plate 1 is bent towards the inner side to form the water blocking member 3, and the upper connecting plate 1 is connected with the water blocking member 3 to form a corner structure.
In this embodiment, the angle between the water blocking component 3 and the bracket of the upper connecting plate 1 is 90 °, and the water blocking component is in an L-shaped structure.
In order to make the water blocking member 3 perform a good blocking function, the width of the water blocking member 3 is set to be 1-25mm, and the water blocking member 3 has a strip-shaped structure with a certain width.
In addition to the above-described structure, the water blocking member 3 may be provided as a bump formed at the lower edge of the upper connection plate 1, the lower edge of the bump being a smooth curved surface.
The bumps can also provide a certain water blocking effect.
It should be noted that the water guide 4 may be disposed along a horizontal direction at an upper edge of the lower connecting plate 2, or may be disposed obliquely, and the water blocking member 3 is disposed in cooperation with the water guide 4 and parallel to each other. The inclined arrangement helps to direct the rapid drainage of rainwater.
It can be understood that the shell connection structure can provide good water retaining and guiding effects for the shell connection parts spliced up and down, so that rainwater is prevented from flowing into the shell through the notch formed at the shell connection part, the water inlet problem at the shell connection part can be effectively solved, the safety of charged components in the shell is improved, and meanwhile, the accumulation of the rainwater at the splicing part can be effectively avoided. In addition, the connecting structure has the advantages of being convenient to splice and assemble.
Example 2:
the embodiment provides an electric appliance casing, which comprises the casing connecting structure and a chassis 5.
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, and at least a part of the area of the chassis 5 protrudes downward to form a slope-shaped drainage member 51.
The slope-shaped drainage piece 51 has a structure as shown in fig. 2, and can be used for guiding water flowing into the casing through the seam of the metal plate and the like to flow, so that the situation that rainwater enters important components due to turbulent flow everywhere to cause potential safety hazards is avoided.
In this embodiment, the drainage members 51 may be disposed along the length or width of the casing, or may be disposed at random or regular points with respect to the surface of the chassis 5.
In order to better protect the equipment located in the casing, as an alternative embodiment, the casing may also be provided with a bottom plate, which is located below the chassis 5 and connected to the lower connecting plate 2, and on which at least one drain hole is provided, through which the rainwater entering the area corresponding to the lower connecting plate 2 via the above-mentioned drainage member 51 or other structure can be drained.
Specifically, the drainage member 51 may be disposed so as to vertically correspond to the drainage hole.
It can be understood that compared with the traditional casing, the electric appliance casing adopting the casing connecting structure solves the problem of water leakage at the joint of the spliced casing, and enables the upper and lower subsection arrangement of the casing to be possible. Meanwhile, the electric appliance shell can be flexibly spliced and detached as required, so that the universality rate of the shell is effectively improved, and the processing cost of the shell is reduced.
Example 3:
the embodiment also provides an electric appliance, which comprises the electric appliance shell.
Specifically, the electric appliance is a two-unit air conditioner, and the whole structure of the electric appliance is shown in fig. 3. Wherein the hot water generator is positioned below the fan, the condenser, the compressor, the matched pipeline and other parts, and the two parts are separated by the chassis 5.
In order to prevent rainwater from flowing into the electrified components of the hot water generator below the base plate 5, a drainage piece 51 is arranged on the corresponding area of the base plate 5 above the hot water generator, and the drainage piece 51 is positioned at a position far away from the electrified components of the hot water generator. The water entering the interior of the shell through the sheet metal joints or the welded joints of the shell can flow to a specific area under the flow guide of the flow guide piece 51, the condition of random flow can not occur everywhere, the possibility that rainwater enters the electrified components is greatly reduced, and the safety of equipment is effectively improved.
It can be understood that taking the two-in-one air conditioner as an example, compared with the traditional two-in-one air conditioner, the two-in-one air conditioner applying the shell connection structure not only solves the problem of water leakage at the joint of the spliced shell, but also enables the upper and lower segmentation arrangement of the shell to be possible. Meanwhile, the shell for installing the hot water generator and the shell for installing the traditional air conditioner component can be separated by the connecting structure, so that the external machine layout with or without the hot water generator component has higher compatibility, the universality of the components is improved effectively, and the processing cost of the shell is reduced greatly.
The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
