[0040] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0041] The embodiments of the present application provide a dispensing device and a clothing processing device to solve the problem that the detergent box of the existing washing machine is built into the body, and water is only introduced into the detergent box through an inlet valve to rinse the detergent box. Due to the limited flushing force and flushing area of ​​the water flow, the stains remaining in the detergent box gradually breed bacteria, affecting the health of the user. The following will be explained with reference to the accompanying drawings.

[0042] The delivery device provided in the embodiment of the present application is applied to a clothing processing device, see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the installation of the delivery device provided in the embodiment of the present application. Figure 2 The schematic diagram of the connection between the dispensing device and the washing drum provided in the embodiment of the present application is as follows. The clothing processing device includes a housing 5 and a washing drum 6. The dispensing device includes a liquid storage bottle 1 and a dispensing pump 2. The liquid storage bottle 1 is detachably mounted vertically on the outer periphery of the housing 5. The bottle mouth of the liquid storage bottle 1 is set away from the ground. The liquid storage bottle 1 is used to store detergent. The dispensing pump 2 is set in the housing 5. The dispensing pump 2 includes a liquid pumping end 21 and a liquid outlet end 22. The liquid pumping end 21 passes through the housing 5 and is connected to the liquid storage bottle 1. The liquid outlet end 22 is used to discharge liquid into the washing drum 6.

[0043] In the dispensing device provided in the embodiment of the present application, the liquid storage bottle 1 is detachably mounted on the outer periphery of the housing 5 of the clothing processing device, and the detergent in the liquid storage bottle 1 is pumped and dispensed into the washing tub 6 by the dispensing pump 2, which not only realizes the automatic and accurate dispensing of the detergent, but also the liquid storage bottle 1 can be directly disassembled to add detergent or clean the liquid storage bottle 1, and the cleaning method is simple and easy to operate, and the liquid storage bottle 1 can be cleaned without sanitary dead corners to avoid the breeding of bacteria, and at the same time, the water inlet valve 3 does not inlet water into the liquid storage bottle 1, so as to avoid the water of the water inlet valve 3 from contaminating the liquid storage bottle 1. In some examples, the dispensing pump 2 can be a peristaltic pump.

[0044] The types of detergents in the present application are not further limited here, for example, they can be washing powder, laundry liquid, softener, disinfectant, etc.

[0045] Optionally, see Figure 4 , Figure 4This is a rear view of the dispensing device provided in the embodiment of the present application, and the dispensing device provided in the embodiment of the present application further comprises a water inlet valve 3 and a water inlet pipe 31. One end of the water inlet pipe 31 is connected to the water inlet valve 3, and the other end of the water inlet pipe 31 is connected to the water inlet valve 3, and water is supplied to the washing tub 6. The water supply direction of the water inlet pipe 31 to the washing tub 6 and the liquid discharge direction of the liquid outlet end 22 to the washing tub 6 intersect with each other, so that water flushes the detergent.

[0046] That is, the extension direction of the end of the water inlet pipe 31 and the extension direction of the end of the liquid outlet end 22 have an intersection, so that the water sprayed from the water inlet pipe 31 can collide with the detergent on the spray path, and then dissolve the detergent, thereby improving the dissolution effect of the detergent. At the same time, rich foam will be generated during the collision between water and detergent in the air, increasing the foaming rate of the detergent.

[0047] Optionally, the water inlet valve 3 can be installed inside the box 5. The installation method of the water inlet valve 3 is not further limited here. It can be detachably installed inside the box 5 through a mounting seat, or welded inside the box 5. The water inlet valve 3 is connected to the water source.

[0048] Optionally, the other end of the water inlet pipe 31 and the end of the liquid outlet end 22 close to the washing tub 6 are arranged adjacent to each other, that is, the end of the water inlet pipe 31 is adjacent to the end of the liquid outlet end 22, so that the detergent can be flushed by water as soon as it escapes from the liquid outlet end 22 of the dosing pump 2, thereby increasing the foaming time of the detergent and thereby improving the foaming rate of the detergent.

[0049] Optionally, the clothes processing device includes a door seal, and the other end of the water inlet pipe 31 and the end of the liquid outlet end 22 close to the washing tub 6 both pass through the door seal and extend above the front of the washing tub 6 .

[0050] Optionally, the angle between the water inlet direction and the gravity direction is 0° to 30°, and the angle between the liquid outlet direction and the water inlet direction is 10° to 50°. That is, the water inlet direction is roughly vertically downward, and the liquid outlet direction of the liquid outlet end 22 is inclined toward the water inlet pipe 31. Since the water inlet demand of the clothing processing equipment is relatively large, the water inlet direction is set to be roughly vertically downward, which can ensure a short water inlet time, water inlet efficiency, and the flushing effect of water impact on the washing drum 6. The demand for detergent delivery is relatively small, so the liquid outlet direction of the liquid outlet end 22 is inclined toward the water inlet pipe 31, and the impact on the washing time is almost negligible.

[0051] The water inlet direction and the liquid outlet direction are not further limited here. In some examples, the angle between the water inlet direction and the gravity direction can be 0°, and the angle between the liquid outlet direction and the water inlet direction is 10°; in other examples, the angle between the water inlet direction and the gravity direction can be 30°, and the angle between the liquid outlet direction and the water inlet direction is 15°; in other examples, the angle between the water inlet direction and the gravity direction can be 15°, and the angle between the liquid outlet direction and the water inlet direction is 30°.

[0052] Optionally, see Figure 3 , Figure 3 for Figure 2 In the cross-sectional view at BB in the middle, the delivery device provided in the embodiment of the present application further includes a liquid extraction tube 4, one end of which is connected to the liquid extraction end 21, and the other end is extended to the bottom of the liquid storage bottle 1, and the liquid extraction tube 4 is made of a flexible material. In some examples, the liquid extraction tube 4 can be made of plastic or rubber.

[0053] When the pump 2 draws detergent through the liquid drawing tube 4, the liquid drawing tube 4 may shake slightly. By setting the liquid drawing tube 4 as a hose, the liquid drawing tube 4 will not scratch the liquid storage bottle 1 even if it is extended to the bottom of the liquid storage bottle 1. This ensures that the liquid drawing tube 4 can draw all the detergent in the liquid storage bottle 1 without causing damage to the liquid storage bottle 1.

[0054] Optionally, the liquid storage bottle 1 may include multiple, and correspondingly, the dispensing pump 2 includes multiple liquid extraction ends 21, each liquid extraction end 21 is connected to a liquid storage bottle 1 through a liquid extraction tube 4, and the multiple liquid storage bottles 1 are arranged at intervals on the outer periphery of the box body 5, and each liquid storage bottle 1 is used to store a detergent to achieve separate storage of different detergents.

[0055] The number of liquid outlet ends 22 is not further limited here. The liquid outlet end 22 may include multiple or one. When the liquid outlet end 22 includes only one, one or more liquid extraction ends 21 are connected to the liquid outlet end 22. When the liquid outlet end 22 includes multiple, each liquid extraction end 21 is connected to one liquid outlet end 22, so as to realize the separate delivery of each detergent and avoid the detergents from crossing each other on the delivery path.

[0056] Optionally, the dispensing device provided in the embodiment of the present application further includes a liquid outlet pipe, one end of which is connected to the liquid outlet end 22 of the dispensing pump 2 , and the other end of which discharges liquid to the washing tub 6 .

[0057] Optionally, see Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the structure of a clothes processing device provided in an embodiment of the present application. Figure 6 for Figure 5 In the partial enlarged view at C in the middle, the liquid storage bottle 1 is made of transparent material, and a liquid level line 11 is provided on the side of the liquid storage bottle 1 facing away from the box body 5. In some examples, the liquid storage bottle 1 can be made of plastic. The number of liquid level lines 11 is not further limited here, and can include a warning line, or multiple liquid level lines 11, wherein the warning line is a prompt line when the liquid level is low. When the liquid level in the liquid storage bottle 1 is lower than or equal to the liquid level, the user needs to add detergent to the liquid storage bottle 1, and when the liquid level line 11 includes multiple liquid level lines 11. Multiple liquid level lines 11 can be arranged at intervals, and the intervals between two adjacent liquid level lines 11 are the same, and the multiple liquid level lines 11 include warning lines.

[0058] The user can directly observe the liquid level in the liquid storage bottle 1 to decide whether to add detergent. At the same time, since the liquid storage bottle 1 is made of transparent material, it is also convenient to directly observe the stains in the liquid storage bottle 1. When there is visible dirt in the liquid storage bottle 1, it can be cleaned in time.

[0059] As an alternative embodiment, only the side wall of the liquid storage bottle 1 facing away from the box body 5 is made of transparent material.

[0060] The embodiment of the present application also provides a clothes processing device, comprising a box 5, a washing tub 6 and a delivery device as described above. The box 5 is provided with a receiving space; the washing tub 6 is installed in the receiving space; and the delivery device is used to discharge liquid into the washing tub 6.

[0061] Optionally, the box body 5 includes a front side wall 51, a side of the front side wall 51 facing away from the accommodation space is recessed with a mounting groove 511, and a projection hole 512 is further provided in the front side wall 51, and the projection hole 512 communicates with the mounting groove 511 and the accommodation space; the liquid storage bottle 1 is installed in the mounting groove 511, and the liquid extraction end 21 passes through the projection hole 512 to communicate with the liquid storage bottle 1. It can be understood that the front side wall 51 of the box body 5 is generally a side wall of the side of the clothing processing device provided with a door body.

[0062] That is, the mounting groove 511 provides a mounting space for the liquid storage bottle 1, and the liquid storage bottle 1 can be directly placed in the mounting groove 511, which is convenient for taking. The mounting groove 511 is arranged on the front side wall 51 of the box body 5, so that the user can directly take the liquid storage bottle 1.

[0063] As an alternative implementation, the mounting groove 511 may also be provided on other side walls of the box body 5, which will not be further described here.

[0064] Optionally, see Figure 7 , Figure 7 for Figure 1 In the cross-sectional view at AA, a connecting column 513 is provided on the front side wall 51, and the connecting column 513 is protrudingly arranged on the side of the mounting groove 511 away from the ground, and the connecting column 513 extends along the gravity direction; a connecting hole 5131 is penetrated in the connecting column 513 along the extension direction, and the extension hole 512 connects the connecting hole 5131 and the accommodating space; the liquid storage bottle 1 is detachably connected to the connecting column 513, and the liquid extraction end 21 passes through the extension hole 512 and the connecting hole 5131 in sequence to communicate with the liquid storage bottle 1. Specifically, one end of the liquid extraction tube 4 is connected to the liquid extraction end 21, and the other end passes through the extension hole 512 and the connecting hole 5131 in sequence to communicate with the liquid storage bottle 1.

[0065] That is, the liquid storage bottle 1 can not only be placed in the mounting groove 511, but also be fixedly connected to the connecting column 513, so as to prevent the liquid storage bottle 1 from being dislodged from the mounting groove 511 and damaged by external force, thereby enhancing the fixing effect of the liquid storage bottle 1. At the same time, the liquid storage bottle 1 and the connecting column 513 are detachably connected, so that the liquid storage bottle 1 can be easily disassembled for cleaning or adding detergent. Since the connecting column 513 extends in the direction of gravity, when the liquid storage bottle 1 and the connecting column 513 are fixedly connected, the liquid storage bottle 1 is in a vertical state, so as to prevent the liquid storage bottle 1 from tilting and leaking detergent.

[0066] Optionally, the connecting column 513 is plugged or screwed with the liquid storage bottle 1. As a specific embodiment, the liquid storage bottle 1 is plugged into the connecting hole 5131 of the connecting column 513; as another specific embodiment, the connecting column 513 is plugged into the bottle mouth of the liquid storage bottle 1; as another specific embodiment, the outer circumference of the bottle mouth of the liquid storage bottle 1 is provided with an external thread, and the connecting hole 5131 of the connecting column 513 is provided with an internal thread, and the liquid storage bottle 1 and the connecting column 513 are screwed together by the external thread and the internal thread; as another specific embodiment, the inner side wall of the bottle mouth of the liquid storage bottle 1 is provided with an internal thread, and the outer circumference of the connecting column 513 is provided with an external thread, and the liquid storage bottle 1 and the connecting column 513 are screwed together by the external thread and the internal thread.

[0067] Furthermore, a sealing ring is provided at the connection between the connecting column 513 and the liquid storage bottle 1 to prevent leakage at the connection between the connecting column 513 and the liquid storage bottle 1 .

[0068] Optionally, a stopper 5132 is convexly provided on the connecting column 513, and when the liquid storage bottle 1 is installed on the connecting column 513, the liquid storage bottle 1 is in contact with the stopper 5132. By providing the stopper 5132, the liquid storage bottle 1 is prevented from being excessively installed with the connecting column 513, such as excessive plugging or screwing, which makes it difficult to remove the liquid storage bottle 1.

[0069] In some examples, the limiting portion 5132 may be a limiting block, which is protruding from the outer periphery of the connecting column 513 . Furthermore, the limiting block may include a pair of blocks, which are relatively arranged on both sides of the connecting column 513 .

[0070] Optionally, the inner diameter of the extension hole 512 can be much larger than the outer diameter of the liquid extraction end 21, so as to facilitate the installation of the liquid extraction end 21. Specifically, the inner diameter of the extension hole 512 can be much larger than the outer diameter of the liquid extraction tube 4, so as to facilitate the installation of the liquid extraction tube 4. Correspondingly, the inner diameter of the connecting hole 5131 can be slightly larger than the outer diameter of the liquid extraction end 21, so as to facilitate the installation of the liquid extraction end 21. Specifically, the inner diameter of the connecting hole 5131 can be slightly larger than the outer diameter of the liquid extraction tube 4, so as to facilitate the installation of the liquid extraction tube 4.
