[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] Example 1
[0019] like Figures 1 to 5A waterproof inverter shown in the figure comprises a box body 1, a plug board 2 is arranged at the rear side of the box body 1, a plurality of electrical sockets 3 are opened on the plug board 2, a rain shield 4 is arranged at the rear side of the box body 1, a guide plate a is arranged on one side of the rain shield 4, and a guide plate b is arranged on the other side of the rain shield 4, a recess 7 is arranged at the rear side of the box body 1, a bracket 8 is connected to the recess 7, a water bottle placement frame 9 is installed in the bracket 8, and a secondary waterproof component 10 is arranged on the plug board 2, including a mounting groove 11, a spring 12, a clamping rod 13 and a rubber belt 14; The rain shield 4, guide plate a and guide plate b are all located above the socket board 2; the guide plate a and guide plate b are both in an inclined state with the left side higher and the right side lower; the length of the guide plate b exceeds the edge of the box body 1, and an inclined groove 15 is connected to the top front side; a funnel 16 is installed on the box body 1 at a position above the water bottle placement frame 9, and a water pipe 17 is connected to the bottom of the funnel 16; the mounting groove 11 is located outside the electrical socket 3, and a clamping rod 13 is symmetrically slidably provided in the mounting groove 11 through a spring 12, and a rubber belt 14 is provided on the inner side of the clamping rod 13.
[0020] The rain shield 4 in the utility model is arranged above the power strip 2, and is made of rubber material. It can effectively intercept the condensed water generated in the refrigerator, and inclined guide plates a and b are arranged on the left and right sides, so that all the condensed water can slide out of the box body 1 to the right, thereby realizing all-round waterproofing above the power strip 2; at the same time, through the inclined groove 15 extending inward, the water flow on the guide plate b is slowly guided to a cluster, and is directly discharged into the collection bottle through the funnel 16, so as to avoid the water flow from being directly spilled and causing damage to other parts in the refrigerator; the surrounding environment is kept dry and tidy, and the circuit and the inverter operate normally.
[0021] Example 2
[0022] like Figures 1 to 5The waterproof inverter shown includes a box body 1, and 4 mounting holes are evenly arranged at the bottom of the box body 1. The inverter can be firmly installed on the compressor through the mounting holes using nuts and other fasteners, and then the inverter is controlled by the power strip 2 arranged at the rear side of the box body 1. In this embodiment, according to the basic three-input power supply setting of the inverter, the number of electrical sockets 3 is set to 3, which can be changed according to the usage scenario and usage requirements; then the wire of the compressor is inserted into the electrical socket 3 to connect it with the terminal and start working. A rain shield 4 is arranged at the rear side of the box body 1. The rain shield 4 is located above the power strip 2 and can intercept the condensed water generated in the refrigerator. The material can be any one with strong waterproofness such as rubber; in order to block multi-directional water flow, a guide plate a is also arranged on the left side of the rain shield 4, and a guide plate b is arranged on the other side, and then the rain shield 4, guide plate a, and guide plate b are all located above the power strip 2 to achieve multi-directional waterproofing for the power strip 2. Among them, guide plate a and guide plate b are both in an inclined state with the left side higher and the right side lower, that is, the lower end of guide plate a is connected to the rain shield 4, and the high end of guide plate b is connected to the rain shield 4. The connection points of the three are all smooth, so that the condensation water falling into guide plate a can slide down into the rain shield 4, and then slide down through guide plate b, and so on, to achieve full waterproofing above the socket board 2.
[0023] Furthermore, the length of the guide plate b will exceed the edge of the box body 1, that is, the water flowing down to the lower right through the guide plate b will be directly discharged outside the box body 1 of the inverter, and will not affect the inverter. In order to prevent the water from spilling directly and causing damage to other components in the refrigerator, a bottle (not shown in the figure) that can collect the water is also provided. A recess 7 is provided on the rear side of the frame of the box body 1, and a bracket 8 is connected to the recess 7. The bracket 8 is installed on the box body 1 through a nut, and a water bottle placement frame 9 is also installed in the bracket 8 through a nut. The bottom of the water bottle placement frame 9 is closed, so the collection bottle can be directly placed in the water bottle placement frame 9 to collect the discharged water and keep the surrounding environment dry and tidy.
[0024] Example 3
[0025] According to the second embodiment, the rain shield 4 is arranged at the rear side of the box 1 to intercept the condensed water generated in the refrigerator. In addition, inclined guide plates a and b are arranged on the left and right sides of the rain shield 4, so that all the condensed water can slide out of the box 1 to the right, and all aspects of the top of the plug board 2 are waterproofed. Therefore, a bottle for collecting water flow is also arranged at the rear side of the frame of the box 1 to keep the surrounding environment dry and tidy; however, the state of the water flow cannot be estimated, and it is impossible to judge whether the water flow can all fall into the collection bottle, so an inclined groove 15 is also arranged on the front side of the top of the guide plate b, and the inclined groove 15 extends inward, which can slowly guide the water flow to a cluster, so as to better cooperate with the collection action.
[0026] In order to prevent water from splashing out and failing to be collected in the bottle, a funnel 16 is installed above the water bottle placement frame 9. The funnel 16 is a vertically elongated opening that can receive all the water flowing out of the guide plate b, and then flow into the collection bottle through the water guide pipe 17 connected at the bottom. The interface between the water bottle and the water guide pipe 17 can be specially treated so that the water entering the water bottle is sealed, thereby preventing the water bottle from being too close to the power strip 2 and being placed in the refrigerator for a long time, causing water molecules to overflow again.
[0027] Example 4
[0028] like Figures 1 to 5 A waterproof inverter shown in the figure is also provided with a secondary waterproof component 10 on the socket board 2 for waterproofing the electrical socket 3, including a mounting groove 11, a spring 12, a clamping rod 13 and a rubber belt 14. The specific mounting structure is as follows: the mounting groove 11 is located on the outside of the electrical socket 3, and the inner side is symmetrically slidably provided with a clamping rod 13 through the spring 12, and a rubber belt 14 is provided on the inner side of the clamping rod 13. After the rubber belt 14 is combined, a rubber ring with a similar outer diameter to the wire interface can be formed. The rubber ring is connected between the electrical socket 3 and the wire interface, thereby realizing the waterproof setting of the electrical socket 3, and further reducing the line paralysis and component damage caused by the contact between the water flow and the terminal.
[0029] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
