[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0039] First, by setting the left heat dissipation hole group 21 and the right heat dissipation hole group 22 respectively behind the heating device 5 and the cold water storage tank 3, when the heating device 5 is working, the air on the left side of the main cavity 10 will become hot first, and the hot air can be dissipated outward through the heat dissipation holes of the left heat dissipation hole group 21. However, because the cold water storage tank 3 is set on the right side of the main cavity 10, the cold air on the right side will actively flow to the left, which allows external cold air to enter the main cavity 10 through the heat dissipation holes of the right heat dissipation hole group 22. The replenishment of cold air can effectively reduce the temperature inside the main cavity 10.

[0040] Second, after the outside air enters the main cavity 10, it will first flow through the cold water storage tank 3. This ensures that the air flowing towards the heating device 5 is relatively cold air, which helps to reduce the temperature inside the main cavity 10.

[0041] Third, the distance H1 between the left heat dissipation hole group 21 and the heating device 5 is greater than the distance H2 between the right heat dissipation hole group 22 and the cold water storage tank 3. On the one hand, the left side of the heating device 5 forms a larger space, and the distance of heat conduction to the outside is relatively longer, which helps to slow down the temperature rise rate of the rear cover 2. On the other hand, the larger space helps to fully mix the hot air with the cold air flowing from the right side, which helps to reduce the temperature of the gas discharged from the main body cavity 10.

[0042] Fourth, by providing left protective nets 71 and right protective nets 72 on the left heat dissipation hole group 21 and the right heat dissipation hole group 22, external dust and small insects can be effectively prevented from entering the main body cavity 10. In addition, the left protective nets 71 and right protective nets 72 can also effectively block water droplets from splashing into the main body cavity 10, which is beneficial to protecting the electrical components inside the product.
