[0002] With the rapid development trend of tobacco industry and mechatronics industry, a new type of heat pump drying room driven by pure electricity has been produced; however, due to the special placement of the heat pump machine, many machines have natural water leakage.

[0003] Existing heat pump electrical cabinets are mostly box structures with wire inlet holes. Although the electrical cabinet is covered by outer sheet metal parts, the outer sheet metal parts will inevitably leak to the outer surface of the electrical cabinet due to erosion by rainwater. The water on the surface of the electrical cabinet then leaks into the interior through the wire inlet holes and the joint seams between the electrical cabinet and the cabinet door, which can cause tripping at the least, affecting the baking process of the heat pump machine. In severe cases, leakage can affect the personal safety of users. Utility Model Content

[0004] In order to solve the above technical problems, the utility model designs a waterproof electrical cabinet for a heat pump machine, which can prevent water from leaking into the interior of the electrical cabinet through the wire inlet hole and prevent water from leaking into the connecting seam between the electrical cabinet and the cabinet door, thereby ensuring the normal and safe use of the electrical cabinet.

[0005] In order to achieve the above technical purpose, the utility model is realized by the following technical scheme: a waterproof electrical cabinet for a heat pump machine, comprising a cabinet body with a wire inlet hole opened on the side, and a cabinet door detachably connected to the cabinet body;

[0006] A bottom plate is welded inside the cabinet, and a plurality of fixing holes for fixing electrical appliances are provided on the bottom plate;

[0007] A sealing rubber ring with an I-shaped cross section is arranged in the wire inlet hole, and the two ends of the sealing rubber ring respectively cover the two end surfaces of the wire inlet hole;

[0008] A connecting frame is integrally formed on the outer edge of the cabinet opening, and the cabinet door is embedded and connected inside the connecting frame; a water-absorbing resin plate having the same size as the cabinet opening is also arranged on the inner side of the cabinet door.

[0009] Preferably, the upper and lower inner side surfaces of the connecting frame are provided with ball pin holes for mating and connection with spring ball pins provided inside the upper and lower surfaces of the cabinet door.

[0010] Preferably, a snap-in hole is provided on the front surface of the connecting frame and is connected to the snap-in rubber column provided on the inner side of the cabinet door through interference fit.

A sealing rubber ring with stretchable elasticity is provided at the wire entry hole to cover and contact the outer surface of the wire, thereby avoiding a gap between the wire and the wire entry hole, which would cause water to enter the cabinet.

[0014] (2) The utility model has an integrally formed connecting frame on the outer edge of the cabinet opening, and the cabinet door is embedded in the connecting frame. The cabinet door has no exposed edge, thereby preventing water leakage from entering the cabinet through the edge of the cabinet door. In addition, a water-absorbing resin plate of the same size as the cabinet opening is provided on the inner side of the cabinet door. The water-absorbing resin plate completely covers the cabinet opening. Even if water leaks into the cabinet through the edge of the cabinet door, the water entering will be absorbed by the water-absorbing resin plate, thereby preventing the water from entering the cabinet and contacting the electrical appliances.

[0015] (3) The upper and lower inner side surfaces of the connecting frame of the utility model are provided with ball pin holes that cooperate with the spring ball pins arranged inside the upper and lower surfaces of the cabinet door, so that the cabinet door can be quickly installed and disassembled, which is convenient for the internal electrical appliance maintenance and quick inspection of the internal situation of the cabinet body; and the front surface of the connecting frame is also provided with a snap-in hole that is interference-fitted with the snap-in rubber column arranged on the inner side of the cabinet door, thereby improving the stability of the cabinet door fixation.
