Description

Technical Field

[0001] The utility model relates to the technical field of electrical appliances, and particularly to an outdoor electrical appliance. Background Art

[0002] Outdoor electrical appliances (such as the outdoor unit of an air conditioner) are generally installed in outdoor environments. In order to enable outdoor electrical appliances (such as the outdoor unit of an air conditioner) to cope with various extreme weather conditions, such as thunderstorm and strong wind weather, outdoor electrical appliances (such as the outdoor unit of an air conditioner) often have rain and moisture protection measures. In particular, the rain and moisture protection measures for the control components inside outdoor electrical appliances (such as the outdoor unit of an air conditioner) are more refined, and the requirements for rain and moisture protection are more stringent. Therefore, the control components inside outdoor electrical appliances (such as the outdoor unit of an air conditioner) are arranged in a relatively enclosed space.

[0003] When the control components are operating, they often generate relatively high temperatures. The relatively enclosed space has an adverse effect on the heat dissipation of the control components, resulting in too high temperatures of the control components, increasing power consumption, and also being prone to local overheating and even the risk of fire. Therefore, in order to better solve the heat dissipation problem of the control components, heat dissipation holes are usually opened on the middle partition between the fan and the control components. By the rotation of the fan, a negative pressure area is generated to promote the air flow inside the outdoor unit and take away the heat of the control components.

[0004] However, in the current structural technology of outdoor electrical appliances, only by taking away the heat of the control components through the heat dissipation holes while ensuring the rain and moisture protection of the control components, it is far from effectively reducing the temperature of the control components. Therefore, the current heat dissipation effect of the control components is poor.

[0005] In summary, in the prior art, for outdoor electrical appliances, while ensuring the rain and moisture protection of the control components, the heat dissipation effect of the control components is poor. Summary of the Utility Model

[0026] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but it is not limited to the present utility model.

[0027] See Figures 1 to 7As shown, according to an embodiment of the present utility model, an outdoor electrical appliance is provided. In this embodiment, the outdoor electrical appliance is an outdoor unit of an air conditioner. The outdoor electrical appliance includes a housing 11 and control components 12. The control components 12 are arranged in an installation space 13 inside the housing 11. The outdoor electrical appliance further includes a handle component 20 connected to the housing 11. The handle component 20 includes a handle main body 21. A ventilation air duct 22 is formed inside the handle main body 21. A first end of the ventilation air duct 22 forms an open structure 22a and is communicated with external air. A second end of the ventilation air duct 22 forms a ventilation opening 22b and is communicated with the installation space 13.

[0028] The second end of the ventilation air duct 22 is located above the first end of the ventilation air duct 22. The open structure 22a and a partial structure of the ventilation air duct 22 form an operation structure for the handle component 20 to be lifted by hand.

[0029] The outdoor electrical appliance of the present utility model improves the existing handle component on the housing. A ventilation air duct is arranged in the handle main body of the handle component. After external air enters the ventilation air duct through the open structure, it is communicated to the installation space from the second end of the ventilation air duct to dissipate heat from the control components. At the same time, the second end of the ventilation air duct is arranged above the first end of the ventilation air duct, that is, the second end of the ventilation air duct is higher than the first end of the ventilation air duct. In this way, even if external rainwater enters the open structure, it cannot flow upward into the installation space, thus achieving the premise of rain and moisture protection for the control components. The outdoor electrical appliance makes full use of the structural space, integrates the ventilation air duct for the control components onto the handle component, and makes full use of the structure of the handle component. It not only ensures rain and moisture protection for the control components, but also communicates external air to the installation space to effectively cool the control components, greatly improving the heat dissipation effect.

[0030] The outdoor electrical appliance of this embodiment will be described and illustrated with an outdoor unit of an air conditioner. Preferably, the ventilation air duct 22 forms at least one bend, and the ventilation air duct 22 has at least one baffle air duct. By improving the shape of the ventilation air duct, it can further prevent external rainwater from entering the second end of the ventilation air duct and improve the rain and moisture protection effect. Refer to Figure 3 As shown by the dotted arrow indicating the air flow direction in the figure, it can be seen that in this embodiment, the ventilation air duct has an S-shaped channel structure, and external air flows through the ventilation air duct in a baffle manner. Such a structural combination can achieve the effect of preventing external water vapor from entering. Of course, the more baffle air ducts the ventilation air duct has, the better the waterproof effect, but the entry of external air will be affected. Therefore, the number of baffle air ducts needs to balance the waterproof effect and the entry effect of external air. The shape of the ventilation air duct can also be L-shaped, C-shaped, etc.

[0031] Refer to Figure 3, the handle component 20 further includes an adsorption component 23, which is arranged at the second end of the ventilation air duct 22. The adsorption component 23 is made of an adsorption material to adsorb the moisture in the external air. By arranging the adsorption component 23, the water vapor in the external air can be further adsorbed to achieve rain and moisture protection.

[0032] Preferably, the handle component 20 further includes a filter screen 24, which is connected above the adsorption component 23. After the external air passes through the ventilation air duct 22 and flows through the adsorption component 23 and the filter screen 24, it enters the installation space 13. The filter screen 24 cooperates with the adsorption component 23 to further adsorb the water vapor in the external air. The filter screen 24 can also filter certain impurities, making the air entering the installation space dry and odorless.

[0033] It should be noted that the structure of the handle main body can be composed of multiple handle covers or can be an integrally formed structure, and the specific structural form is not limited. The multiple structures at the second end of the ventilation air duct form a ventilation module as a whole. The handle main body is not only connected to the housing so that the open structure is located on the surface of the housing, but also connected to other support structures or components inside the air conditioner outdoor unit to increase stability and the function of the handle. One end of the ventilation module is connected to the upper end of the handle component through a card slot. Such a structure can be assembled together very conveniently, and the assembled new handle can also be well installed on the outdoor unit. Moreover, the ventilation module structure is hidden inside the outdoor unit and has no impact on the appearance of the outdoor unit.

[0034] The handle component 20 further includes a water blocking tongue 25, which is located at the second end position of the ventilation air duct 22. The first end of the water blocking tongue 25 is connected to the inner wall of the ventilation air duct 22, and a flow deflection channel 25a is formed between the second end of the water blocking tongue 25 and the inner wall of the ventilation air duct 22. The cross-sectional area of the flow deflection channel 25a is smaller than the cross-sectional area of the ventilation air duct 22.

[0035] The water blocking tongue 25 on the ventilation air duct will cause the water vapor in the external air to condense on the water blocking tongue 25, and the condensed water vapor will flow from the water blocking tongue to the first end of the ventilation air duct. The water blocking tongue plays a certain waterproof role. At the same time, the flow deflection channel formed between the water blocking tongue and the ventilation air duct also forms a flow deflection air duct, which can block the entry of external water vapor. The overall shape of the water blocking tongue 25 is matched according to the ventilation air duct.

[0036] Preferably, the second end of the water retaining tongue 25 is higher than the first end of the water retaining tongue 25, and the windward surface of the water retaining tongue 25 is an inclined surface. In other words, the second end of the water retaining tongue 25 is above the first end of the water retaining tongue 25. Such a structure is conducive to the water condensed on the water retaining tongue to flow downward, increasing the fluidity of water vapor, so that the water vapor is not too much concentrated on the second end of the water retaining tongue or the ventilation duct, thereby improving the rainproof and waterproof performance. The windward surface of the water retaining tongue is inclined downward, that is, inclined toward the first end of the ventilation duct, which is conducive to the water flow flowing downward. Among them, the windward surface of the water retaining tongue can be a curved surface or a flat surface.

[0037] Furthermore, the adsorption component 23 is arranged on the water retaining tongue 25, and the adsorption component 23 is located above the water retaining tongue 25. The water retaining tongue 25 is provided with a water guide groove 25b. The water vapor adsorbed by the adsorption component 23 converges to form a water flow and is discharged downward from the water guide groove 25b.

[0038] The adsorption component 23 and the water retaining tongue 25 form a structural match. The adsorption component 23 is used to absorb water vapor and converge to form a water flow. Under the action of gravity, the water flow flows downward to the upper surface of the water retaining tongue 25, and flows from the water guide groove 25b (through groove or through hole structure) through the water retaining tongue 25 to the first end of the ventilation duct. In this way, the water vapor adsorbed by the adsorption component 23 can be discharged in time, ensuring that the module formed at the second end of the ventilation duct is dry and odorless, preventing mildew and improving the rain and moisture-proof effect. In addition, the structure and position of the adsorption component and the water retaining tongue form a high degree of match, cleverly utilizing the structural space of the handle component, and achieving more technical effects with the least structure.

[0039] In order to further enhance the flow of water, in this embodiment, the surface of the water retaining tongue 25 is an arc surface, and the inner wall of the ventilation duct 22 is an arc surface. The arc surface can guide the water flow to flow quickly, and will not cause water accumulation at a certain position inside the ventilation duct, so that the water flow in the ventilation duct can be discharged as much as possible, and the moisture-proof effect is better. Among them, the upper surface of the water retaining tongue is a concave arc surface, which, in conjunction with the structure of the water guide groove, can collect water vapor in the adsorption material, so that the water vapor quickly gathers in the water guide groove below the arc concave surface, and the drainage efficiency is higher.

[0040] See also Figure 6 and Figure 7 A partition 14 is provided inside the shell 11 of the air conditioner outdoor unit, and the partition 14 encloses the installation space 13. The partition 14 is provided with heat dissipation holes 15, and the installation space 13 is connected to the heat dissipation duct inside the shell 11 through the heat dissipation holes 15.

[0041] There are multiple partition plates 14, which enclose a relatively airtight installation space 13, so that the internal control components can be maximally protected from rain and moisture. The heat dissipation holes 15 opened on the partition plates 14 are used to form a new heat dissipation flow path. Refer to Figure 6 and Figure 7 In the figure, the dotted line indicates the air flow direction. By rotating the fan, a negative pressure area A is generated, which promotes the air flow inside the housing, takes away the heat of the control components. At the same time, the external air entering from multiple open structures enters the installation space 13. After the external air takes away the heat, it enters the internal heat dissipation air duct through the heat dissipation holes 15 and is discharged to the outside through the grille, thus forming an air flow cycle. Through the cooperation of the heat dissipation holes 15 and the handle component, the air-cooled heat dissipation effect of the control components is greatly improved, and the internal temperature of the installation space is effectively reduced.

[0042] Figure 1 and Figure 2 and Figure 6 and Figure 7 It more clearly shows the improvement effect of the improvement of the handle component on the heat dissipation of the control components in the outdoor unit of the air conditioner. By partially cutting open the upper end of the outdoor unit of the air conditioner, the positional relationship between the internal control components and the handle component can be seen. When the outdoor unit of the air conditioner is running, the fan inside the outdoor unit rotates, and a negative pressure area A will be generated in the area shown in the figure. The ventilation air duct of the handle component serves as a medium channel between the inside and outside of the outdoor unit of the air conditioner, which can promote the cold air in the environment to flow in from the open structure, enter the installation space inside the outdoor unit of the air conditioner, and then pass through between the control components, taking away the heat in the control components and playing a role in dissipating heat and cooling the control components.

[0043] In order to further improve the effect of the external air entering the installation space from the handle component, in this embodiment, there are multiple handle components 20, and the orientations of the open structures 22a of the multiple handle components 20 are staggered. The staggered orientation of the open structures 22a can increase the intake of external air for each handle component and effectively improve the heat dissipation effect. The number of handle components 20 can be set according to the external size of the outdoor unit of the air conditioner, and preferably 2.

[0044] In an embodiment not shown in the figure of the present utility model, an outdoor electrical appliance is further provided. The structure of the outdoor electrical appliance is the same as that of the above embodiment, except that the outdoor electrical appliance in this embodiment is an electrical control box.
