Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of clothes dryers, and in particular to a clothes dryer. Background Art
[0002] In the prior art, a clothes dryer includes a drum and a rotating shaft, wherein a bearing is installed on the rotating shaft. The bearing is generally arranged on the housing and directly exposed to the air path between the housing and the rear cover. Since the high-temperature hot air generated by the heater flows into the air path, the bearing is directly placed in a high-temperature environment. In order to prevent the bearing temperature from being too high, metal bearings and high-temperature resistant grease are usually required, and plastic bearings with better sliding effects cannot be used. The use of metal bearings has the following problems: first, the cost is high, second, the metal bearings are easily damaged, and third, the high-temperature grease will also be worn out in a long-term high-temperature environment, which eventually leads to poor bearing rotation, causing the machine to produce abnormal noise, thereby affecting the use of the clothes dryer. Summary of the invention

[0014] Furthermore, a heater is provided inside the box, and the heater is provided corresponding to the air outlet.
[0015] Furthermore, the bearing is made of plastic.
[0016] Beneficial effects of the present invention:
[0017] The present invention isolates the bearings arranged on the box body by setting a sealing chamber between the box body and the cover plate, thereby avoiding the bearings being directly exposed to the air path between the box body and the rear cover plate, effectively preventing the bearing temperature from being too high, and effectively preventing the grease from being easily lost due to being in a high temperature environment for a long time, which ultimately leads to poor rotation of the bearing and abnormal noise of the machine.

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.
[0029] This embodiment provides a clothes dryer, such as Figure 1-Figure 6 As shown, it includes a box body 1 and a rear cover plate 2 connected to the box body 1 , a sealing chamber 3 is provided between the box body 1 and the rear cover plate 2 , and the sealing chamber 3 is used to seal the bearing on the box body 1 .
[0030] In this embodiment, a sealing chamber 3 is provided between the housing 1 and the cover plate to isolate the bearings provided on the housing 1, thereby preventing the bearings from being directly exposed to the air path between the housing 1 and the rear cover plate 2. This can effectively prevent the bearing temperature from being too high and the grease from being easily lost due to being in a high temperature environment for a long time, which ultimately leads to poor bearing rotation and abnormal noise from the machine.
[0031] like Figure 3 As shown, the sealing chamber 3 includes an end cover 31 and a fixing seat 32 connected to the end cover 31, the end cover 31 is arranged on the rear cover plate 2, and the fixing seat 32 is arranged on the box body 1. In this embodiment, by arranging the fixing seat 32 on the box body 1 and the end cover 31 on the rear cover plate 2, the sealing of the bearing can be achieved, and the bearing is prevented from being directly exposed to the space between the box body 1 and the rear cover plate 2 and being affected by the hot air between the box body 1 and the rear cover plate 2. Among them, the fixing seat 32 is an annular boss protruding from the box body 1, and is an integral structure with the box body 1.
[0032] like Figure 5 As shown, the rear cover plate 2 is provided with a protrusion 21 on one side close to the box body 1, and the protrusion 21 is penetrated with a mounting hole 22, and the mounting hole 22 is provided with a connecting surface 23 at one end close to the fixing seat 32, and the end cover 31 is sequentially connected to the connecting surface 23 and the fixing seat 32. In this embodiment, the end cover 31 is fixedly connected to the connecting surface 23 and the fixing seat 32 in sequence by screws or other fasteners.
[0033] This embodiment also provides a configuration method of the end cover 31 and the rear cover plate 2, specifically, as follows: Figure 6 As shown, the end cover 31 and the rear cover plate 2 are an integral structure, and the end cover 31 is convexly arranged on the side of the rear cover plate 2 away from the box body 1, wherein the end cover 31 is circumferentially provided with a step surface 311, and when the rear cover plate 2 is fixed on the box body 1, the step surface 311 presses against the fixing seat 32, thereby sealing the bearing in the sealing chamber 3 formed by the fixing seat 32 and the end cover 31. It should be noted that the present embodiment does not limit the two configuration modes of the end cover 31, and can be selected according to actual needs.
[0034] like Figure 4 As shown, the box body 1 is provided with a groove 11, and the space between the groove 11 and the rear cover plate 2 forms an air supply cavity (not shown), and the air supply cavity is used for hot air to pass through; wherein, the groove 11 includes a first groove 111 and a second groove 112, and the fixing seat 32 is arranged in the first groove 111. In addition, an air inlet 1121 is also arranged in the first groove 111, and an air outlet 1111 is arranged in the second groove 112. A heater is arranged inside the box body 1, and the air outlet 1111 is arranged corresponding to the heater, so that the hot air generated by the heater can pass through the air supply cavity from the air outlet 1111, and enter the inside of the cylinder of the box body 1 from the air inlet 1121 to dry the clothes in the cylinder.
[0035] The air inlet 1121 and the air outlet 1111 are respectively disposed at two ends of the groove 11. Figure 4 As shown, specifically, it is arranged above and below the fixing seat 32, and the hot air flowing out of the air outlet 1111 is blocked by the sealed chamber 3, so that the hot air passes through both sides of the sealed chamber 3, as shown in FIG. Figure 4 The direction of the middle arrow indicates the flow direction of the hot air, thereby avoiding the high temperature influence of the hot air in the air supply chamber on the bearing, and at the same time avoiding the high temperature of the grease, thereby avoiding the situation where the bearing rotates poorly due to the high temperature of the grease.
[0036] Preferably, the bearing is made of plastic. Compared with metal bearings, plastic bearings have better sliding effect and low production cost, and avoid the situation in which the technical bearings are easily damaged when metal bearings are used in the prior art.
[0037] Note that the above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected, and the scope of the present invention to be protected is defined by the attached claims and their equivalents.
