Abstract
Description
Technical Field
[0001] The utility model relates to a metal plate for a washing machine rear shell with a heat dissipation structure, belonging to the technical field of washing machine accessories. Background Art
[0002] The metal sheet used for the washing machine rear housing has the strength and formability of steel. After being treated with a zinc-plating process, zinc and iron atoms form a dense and uniform zinc-iron alloy layer on the substrate surface, which offers better corrosion resistance than standard galvanized steel. Even in complex operating environments, it maintains excellent stability and is resistant to rust and corrosion, meeting the needs of long-term washing machine use.
[0003] There are still some problems with the use of the existing metal plates used in the rear shell of washing machines. For example, during use, the washing machine may overheat internally due to long-term operation. The metal plate has certain thermal insulation properties and strong thermal conductivity. It is difficult to quickly discharge the heat only through the heat dissipation windows inside the metal plate, which leads to the temperature of the metal plate on the rear shell of the washing machine being too high. Utility Model Content
[0004] The purpose of the present invention is to provide a metal plate for the rear shell of a washing machine with a heat dissipation structure. The present invention has a simple structure and is easy to use. It can accelerate the evacuation of hot air inside the washing machine, so that the metal plate has a good heat dissipation effect, thereby solving the problems raised in the above-mentioned background technology.
[0005] To achieve the above objectives, the present invention provides the following technical solutions:
[0006] A metal plate for the rear shell of a washing machine with a heat dissipation structure includes a metal plate body, screws are installed on the outside of the metal plate body, a heat dissipation window is opened inside the metal plate body, an air pressure box is fixedly connected to the outside of the metal plate body, an air inlet hole is opened in the inner wall of the air pressure box, a slide is slidably connected to the inside of the air pressure box, a No. 1 return spring is fixedly connected to the outside of the slide, a push rod is fixedly connected to the outside of the slide, a power box is fixedly connected to the outside of the metal plate body, a switch is provided on the top of the power box, a connecting plate is fixedly connected to the top of the power box, a No. 2 return spring is fixedly connected to the outside of the switch, a motor is fixedly connected to the bottom of the power box, and a fan blade is fixedly connected to the bottom of the motor output end.
[0007] Furthermore, an extrusion rod is fixedly connected to the outside of the output end of the motor, the outside of the metal plate body is fixedly connected to the operating box, the inside of the operating box is fixedly connected to an elastic airbag, the bottom of the elastic airbag is fixedly connected to a conduit, the bottom of the conduit is fixedly connected to an air outlet plate, the outside of the operating box is movably connected to a moving rod, the outside of the moving rod is fixedly connected to a force cover, and the inside of the force cover is fixedly connected to a No. 3 return spring.
[0008] Furthermore, the air inlet holes are evenly distributed in the inner wall of the air pressure box, and the No. 1 return spring is symmetrically distributed between the slide plate and the inner wall of the air pressure box. By opening the air inlet holes in the inner wall of the air pressure box, the hot air generated by the washing machine working for a long time will enter the interior of the air pressure box through the air inlet holes.
[0009] Furthermore, the push rod crosses the inner wall of the air pressure box, and the end of the push rod away from the slide is located outside the switch. When the air pressure increases, the slide slides inside the air pressure box, thereby moving the push rod outside the switch.
[0010] Furthermore, the power box is electrically connected to the motor, and the fan blades are located on the top outside of the heat dissipation window. When the push rod pushes the switch, the power box will be energized, thereby starting the motor at the bottom.
[0011] Furthermore, the extrusion rods are evenly distributed outside the output end of the motor, and the running box is distributed outside the metal plate body. When the motor is started, the extrusion rods at the bottom thereof are driven to rotate, so that the extrusion rods intermittently squeeze the stress cover.
[0012] Furthermore, one end of the No. 3 return spring away from the force cover is fixedly connected to the outside of the operating box, and the other end of the moving rod away from the force cover is located on the outside of the elastic airbag. By using the moving rod in conjunction with the No. 3 return spring, the moving rod can intermittently squeeze the elastic airbag, causing the gas inside the elastic airbag to be ejected through the air outlet plate.
[0013] The beneficial effects of the utility model are:
[0014] (1) The utility model is provided with a metal plate body, and a heat dissipation window is opened inside the metal plate body. When the metal plate body is installed at the rear end of the washing machine, the washing machine will generate high temperature after long-term operation. At this time, the hot air will enter the interior of the air pressure box through the air inlet hole in the inner wall of the air pressure box. At this time, the air pressure inside the air pressure box will increase, causing the slide to move inside the air pressure box. The movement of the slide drives the push rod to move, so that the push rod turns on the switch. At this time, the power box will be energized, so that the motor at the bottom of the power box will start. The start of the motor causes the fan blades at the bottom output end to rotate, and the generated wind force will accelerate the air circulation speed outside the heat dissipation window, thereby accelerating the dissipation of hot air inside the washing machine.
[0015] (2) The utility model is provided with a metal plate body. When the power box is powered on to start the motor, the output end of the motor will drive the extrusion rod to rotate. At this time, the extrusion rod will intermittently squeeze the force-bearing cover, so that the moving rod inside the force-bearing cover moves inside the operating box. By cooperating with the No. 3 return spring, the moving rod will intermittently squeeze the elastic airbag inside the operating box, so that the gas inside the elastic airbag enters the interior of the air outlet plate through the conduit and is ejected from the air outlet plate. The air outlet plate is located on the top outside of the heat dissipation window, so it can clean larger dust or particles adsorbed on the surface of the heat dissipation window.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] Example 1, please refer to Figure 1-Figure 4 , the utility model provides a technical solution:
[0024] The metal plate for the rear shell of a washing machine with a heat dissipation structure includes a metal plate body 1, screws 2 are installed on the outside of the metal plate body 1, a heat dissipation window 3 is opened inside the metal plate body 1, an air pressure box 4 is fixedly connected to the outside of the metal plate body 1, an air inlet hole 5 is opened in the inner wall of the air pressure box 4, a slide plate 6 is slidably connected to the inside of the air pressure box 4, a No. 1 return spring 7 is fixedly connected to the outside of the slide plate 6, a push rod 8 is fixedly connected to the outside of the slide plate 6, a power box 9 is fixedly connected to the outside of the metal plate body 1, a switch 10 is provided on the top of the power box 9, a connecting plate 11 is fixedly connected to the top of the power box 9, a No. 2 return spring 12 is fixedly connected to the outside of the switch 10, a motor 13 is fixedly connected to the bottom of the power box 9, and a fan blade 14 is fixedly connected to the bottom of the output end of the motor 13.
[0025] Specifically, such as Figure 1 As shown, the air inlet holes 5 are evenly distributed in the inner wall of the air pressure box 4, the No. 1 return spring 7 is symmetrically distributed between the slide 6 and the inner wall of the air pressure box 4, the push rod 8 crosses the inner wall of the air pressure box 4, and the end of the push rod 8 away from the slide 6 is located on the outside of the switch 10, the power box 9 is electrically connected to the motor 13, and the fan blades 14 are located on the outside of the top of the heat dissipation window 3.
[0026] Furthermore, by opening an air inlet hole 5 in the inner wall of the air pressure box 4, the hot air generated by the long-term operation of the washing machine will enter the interior of the air pressure box 4 through the air inlet hole 5. As the air pressure increases, the slide plate 6 slides inside the air pressure box 4, thereby causing the push rod 8 to move on the outside of the switch 10. When the push rod 8 pushes the switch 10, the power box 9 will be energized, thereby starting the motor 13 at its bottom.
[0027] In this embodiment: a metal plate body 1 is provided, and a heat dissipation window 3 is opened inside the metal plate body 1. When the metal plate body 1 is installed at the rear end of the washing machine, the washing machine will generate high temperature after long-term operation. At this time, the hot air will enter the interior of the air pressure box 4 through the air inlet hole 5 in the inner wall of the air pressure box 4. At this time, the air pressure inside the air pressure box 4 will increase, causing the slide plate 6 to move inside the air pressure box 4. The movement of the slide plate 6 drives the push rod 8 to move, so that the push rod 8 turns on the switch 10. At this time, the power box 9 will be energized, so that the motor 13 at the bottom thereof will be started. The start of the motor 13 causes the fan blades 14 at the bottom output end to rotate, and the generated wind force will accelerate the air circulation speed outside the heat dissipation window 3, thereby accelerating the dissipation of heat inside the washing machine.
[0028] Example 2, please refer to Figure 1 、 Figure 2 and Figure 4 The difference between this embodiment and embodiment 1 is that: an extrusion rod 15 is fixedly connected to the outer side of the output end of the motor 13, an operating box 16 is fixedly connected to the outer side of the metal plate body 1, an elastic airbag 17 is fixedly connected to the inside of the operating box 16, a conduit 18 is fixedly connected to the bottom of the elastic airbag 17, an air outlet plate 19 is fixedly connected to the bottom of the conduit 18, a moving rod 20 is movably connected to the outer side of the operating box 16, a force-bearing cover 21 is fixedly connected to the outer side of the moving rod 20, and a No. 3 return spring 22 is fixedly connected to the inner side of the force-bearing cover 21.
[0029] Specifically, such as Figure 1-4 As shown, the extrusion rod 15 is evenly distributed on the outside of the output end of the motor 13, the operating box 16 is distributed on the outside of the metal plate body 1, the end of the No. 3 return spring 22 away from the force cover 21 is fixedly connected to the outside of the operating box 16, and the end of the moving rod 20 away from the force cover 21 is located on the outside of the elastic airbag 17.
[0030] Specifically, the motor 13 is started to drive the extrusion rod 15 at its bottom to rotate, so that the extrusion rod 15 intermittently squeezes the force-bearing cover 21. By using the moving rod 20 in conjunction with the No. 3 return spring 22, the moving rod 20 can intermittently squeeze the elastic airbag 17, so that the gas inside the elastic airbag 17 is ejected through the air outlet plate 19.
[0031] In this embodiment: by setting up a metal plate body 1, when the power box 9 is energized to start the motor 13, the output end of the motor 13 will drive the extrusion rod 15 to rotate, and at this time the extrusion rod 15 will intermittently squeeze the force-bearing cover 21, so that the moving rod 20 inside the force-bearing cover 21 moves inside the operating box 16, and the moving rod 20 is used in conjunction with the No. 3 return spring 22, so that the moving rod 20 intermittently squeezes the elastic airbag 17 inside the operating box 16, so that the gas inside the elastic airbag 17 enters the interior of the air outlet plate 19 through the conduit 18, and then is ejected from the air outlet plate 19. The air outlet plate 19 is located on the top outside of the heat dissipation window 3, so it can clean larger dust or particles adsorbed on the surface of the heat dissipation window 3.
