Abstract
Description
Technical Field
[0001] This application relates to the field of electrical manufacturing technology, and in particular to a garment processing device. Background Technology
[0002] Washing machines are divided into bottom-drain washing machines and top-drain washing machines. Bottom-drain washing machines do not use a drain pump when draining water and are suitable for scenarios where the washing machine drain outlet is higher than the floor drain. They use the height difference between the washing machine drain outlet and the floor drain for natural drainage. Top-drain washing machines use a drain pump to drain water and are suitable for scenarios where the floor drain is higher than the washing machine drain outlet. They use the pressurization effect of the drain pump for forced drainage.
[0003] However, when a top-loading drum washing machine uses a drain pump to drain water, if there is air in the drain pipe, especially in the blade area of the drain pump, it will reduce the drainage efficiency, commonly known as "air trapping". If the air trapping is severe during spin drying, the water in the outer drum cannot be discharged in time. The rotating inner drum hits the water surface at the bottom of the outer drum that cannot be discharged, resulting in a lot of noise during spin drying with water, and the spin drying power increases, resulting in a poorer spin drying effect.

[0040] Please see Figures 1 to 7 This application provides a garment processing device 100, including a cylinder 20, a drain pump 31, an air guide pipe 32, and a water box 33. The cylinder 20 is provided with a water outlet; the inlet of the drain pump 31 is connected to the water outlet on the cylinder 20; the air guide pipe 32 is connected to the drain pump 31 and communicates with the inner cavity of the drain pump 31; the other end of the air guide pipe 32 is connected to the water box 33 and communicates with the inner cavity of the water box 33.
[0041] For example, the air guide pipe 32 is connected to the top of the drain pump 31, that is, the air outlet of the drain pump 31 is located at its top.
[0042] For example, the garment processing device 100 can be a drum washing machine, a drum washer-dryer combo, or a drum dryer.
[0043] For example, the water box 33 is used to dispense detergent, introduce washing water into the drum 20, and / or collect condensate collected during the drying process.
[0044] For example, the garment processing device 100 further includes an inner cylinder disposed inside the cylinder body 20, that is, the cylinder body 20 is an outer cylinder.
[0045] The garment processing device 100 provided in this application embodiment has an air guide pipe 32. One end of the air guide pipe 32 is connected to the inner cavity of the drain pump 31, and the other end is connected to the inner cavity of the water box 33. Since the water box 33 is connected to the external environment, the air guide pipe 32 can be used to guide the gas inside the drain pump 31 into the water box 33 and then discharge it into the external environment. This can eliminate or reduce the "trapped air" phenomenon of the drain pump 31, reduce or eliminate the dehydration noise of the garment processing device 100, and reduce the dehydration power and improve the dehydration effect.
[0046] Please see Figure 3 , Figure 4 and Figure 7The drainage pump 31 is located below the cylinder 20, and the water box 33 is located above the cylinder 20.
[0047] Please see Figure 1 and Figure 2 See also Figure 5 and Figure 6 The garment processing device 100 also includes a housing 40, with the cylinder 20 and the drain pump 31 both disposed inside the housing 40. The housing 40 includes a first side plate 41, a second side plate 42, and a back plate 43. The first side plate 41 and the second side plate 42 are disposed opposite to each other, and the back plate 43 is disposed between the first side plate 41 and the second side plate 42. One side of the first side plate 41 and one side of the second side plate 42 are both connected to the back plate 43.
[0048] Please see Figure 3 , Figure 4 and Figure 7 The cylinder 20 has an inlet 21 and a rear cover 22 that are disposed opposite to each other.
[0049] Please see Figure 3 , Figure 4 and Figure 7 The garment processing device 100 also includes a drain pipe 50, one end of which is connected to the drain pump 31 and communicates with the outlet of the drain pump 31.
[0050] Please see Figure 3 , Figure 4 and Figure 7 The garment processing device 100 also includes a lint filter 34, which is disposed between the cylinder 20 and the drain pump 31. The outlet of the cylinder 20 is connected to the inlet of the lint filter 34, and the outlet of the lint filter 34 is connected to the outlet of the drain pump 31.
[0051] It is understandable that by installing a wire lint filter 34 between the cylinder 20 and the drainage pump 31, the water discharged from the cylinder 20 can be filtered to remove wire lint from the water, thereby preventing the wire lint from getting tangled in the impeller of the drainage pump 31, which would obstruct the impeller's rotation and cause poor drainage. At the same time, it can also prevent the wire lint in the water from polluting the environment.
[0052] Please see Figure 3 and Figure 4 In the first embodiment, the housing of the lint filter 34 and the housing of the drain pump 31 are integrally formed, the inner cavity of the lint filter 34 is connected to the inner cavity of the drain pump 31, and both the drain pump 31 and the lint filter 34 are located close to the discharge port 21.
[0053] Please see Figure 3 and Figure 4 The drain pipe 50 includes a first ascending section 51, a first horizontal section 52, and a first descending section 53 connected in sequence. The first horizontal section 52 is located above the cylinder 20, and the end of the first descending section 53 is lower than the first horizontal section 52. (See also...) Figure 1 and Figure 2 A portion of the first rising section 51 extends along the inner wall of the first side plate 41, a portion of the first horizontal section 52 extends along the inner wall of the first side plate 41, and another portion enters the outer side of the housing 40 and extends along the outer wall of the back plate 43, and the first descending section 53 extends along the outer wall of the back plate 43.
[0054] It should be noted that in existing top-loading washing machines, the drain pipe typically tends to run downwards first and then upwards. That is, there is a recessed section in the middle of the drain pipe, located below the drain pump. Because gas naturally rises, the gas in this recessed section of the drain pipe will naturally rise and easily enter the drain pump, causing a "trapped air" phenomenon. However, in the first embodiment of this application, as... Figure 3 and Figure 4 As shown, the drain pipe 50 first goes upward, then extends horizontally, and finally goes downward to achieve drainage. That is to say, there is no sinking section in the drain pipe 50 of the first embodiment of this application. Therefore, it is not easy for gas in the drain pipe 50 to enter the drain pump 31 in reverse, thereby reducing or eliminating the "trapped gas" phenomenon of the drain pump 31.
[0055] Please see Figure 7 In the second embodiment, a first connecting pipe 71 is provided between the lint filter 34 and the drain pump 31. The lint filter 34 is located near the discharge port 21, and the drain pump 31 is located near the rear cover 22.
[0056] Please see Figure 7 The drain pipe 50 includes a second rising section 61, a second horizontal section 62, and a second descending section 63 connected in sequence, wherein the second horizontal section 62 is located above the cylinder 20, and the end of the second descending section 63 is lower than the second horizontal section 62; see also Figure 5 and Figure 6 A portion of the second rising section 61 enters the outside of the housing 40 and extends along the outer wall of the back plate 43, while the second horizontal section 62 and the second descending section 63 both extend along the outer wall of the back plate 43.
[0057] like Figure 7As shown, the drain pipe 50 in the second embodiment of this application also moves upward first, then extends horizontally, and finally moves downward to achieve drainage. That is to say, there is no sinking section in the drain pipe 50 in the second embodiment of this application. Therefore, it is not easy for gas in the drain pipe 50 to enter the drain pump 31 in reverse, thereby reducing or eliminating the "trapped gas" phenomenon of the drain pump 31.
[0058] Please see Figure 3 , Figure 4 and Figure 7 A second connecting pipe 72 is provided between the water outlet of the cylinder 20 and the inlet of the lint filter 34. Exemplarily, the second connecting pipe 72 includes a corrugated pipe.
[0059] Please see Figure 1 and Figure 5 The housing 40 includes a front horizontal plate 44, which is disposed opposite to the back plate 43. The side of the first side plate 41 facing away from the back plate 43 and the side of the second side plate 42 facing away from the back plate 43 are both connected to the front horizontal plate 44. The lint filter 34 is connected to the front horizontal plate 44.
[0060] For example, the lint filter 34 includes a housing and a cover. The housing has an opening, and the cover is rotatably connected to the housing to seal or open the opening. The front cross plate 44 is provided with a through hole, which is provided corresponding to the opening of the housing to expose the cover, thereby facilitating user operation of the cover.
[0061] For example, the housing of the lint filter 34 is connected to the front cross plate 44, and the specific connection method can be screw connection, etc.
[0062] The clothing processing equipment provided in the embodiments of this application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand this application. Furthermore, those skilled in the art will recognize that, based on the ideas of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
