[0041] The embodiments of the present application provide a washing device, which includes the detergent feeding device 1 of any embodiment of the present application.

[0042] Exemplarily, the washing apparatus comprises a drum assembly having a laundry processing cavity and a laundry loading port for accommodating washing articles, which can be laundry, shoes, carpets, etc., and a user can load or take out the washing articles through the laundry loading port.

[0043] In some embodiments, the drum assembly can only comprise a washing drum, which can hold washing water and accommodate laundry. In other embodiments, the drum assembly can further comprise an outer tub, and the washing drum is arranged in the outer tub, the outer tub is used to hold washing water, and the washing drum is used to hold laundry. Of course, in yet other embodiments, the drum assembly can comprise a washing drum and an outer tub, the washing drum can hold washing water and accommodate laundry, and the water in the washing drum will not enter the outer tub.

[0044] The detergent dispensing device 1 is in communication with the drum assembly. The detergent dispensing device 1 is used to dispense detergent to the drum assembly.

[0045] The second aspect of the embodiments of the present application provides a detergent dispensing device 1, which is described in detail with reference to Figures 1 to 4 , comprising a detergent box 10, a liquid guide pipeline 11, an extraction mechanism (not shown in the figure) and a blocking structure 12.

[0046] The detergent box 10 has a cavity 101 for accommodating detergent. It can be understood that the cavity 101 in the detergent box 10 can provide space for the detergent, which is convenient for the user to supplement the detergent required by the washing apparatus.

[0047] It should be noted that the type of detergent is not limited, which can be a lotion with a stain cleaning effect, or a perfume, a disinfectant, or a laundry care agent for softening, fluffing and removing static electricity of laundry, etc.

[0048] The liquid guide pipeline 11 is in communication with the cavity 101, and the first end 11b of the liquid guide pipeline 11 is located in the cavity 101 and extends towards the bottom wall of the detergent box 10. For example, the first end 11b of the liquid guide pipeline 11 extends in the up-down direction.

[0049] In the related art, when the amount of detergent is small, the detergent will gather at the bottom wall of the detergent box, causing the phenomenon of liquid accumulation in the detergent box. In the embodiments of the present application, the first end 11b of the liquid guide pipeline 11 extends towards the bottom wall of the detergent box 10, so that the detergent at the bottom of the detergent box 10 can flow to the liquid guide pipeline 11, thereby reducing the phenomenon of liquid accumulation in the detergent box 10.

[0050] The extraction mechanism is in communication with the second end of the liquid guide pipeline 11 and is used to extract the detergent in the cavity 101 through the liquid guide pipeline 11. That is, under the action of the extraction mechanism, the detergent in the cavity 101 is sucked into the liquid guide pipeline 11 through the liquid inlet groove 11a of the first end 11b, and the automatic dispensing of the detergent is realized through the extraction mechanism.

[0051] It should be noted that the specific structure of the extraction mechanism is not limited, and can be a power device such as a liquid extraction pump.

[0052] Please refer to Figure 7 The blocking structure 12 is connected with the detergent box 10, that is, the blocking structure 12 is arranged on the detergent box 10. And a gap 1a for the flow of detergent is formed between the blocking structure 12 and the side wall of the liquid guide pipeline 11, and the gap 1a is in communication with the internal space of the liquid guide pipeline 11.

[0053] The detergent feeding device 1 in the embodiment of the application, through the gap 1a formed between the blocking structure 12 and the side wall of the liquid guide pipeline 11, on the one hand, can allow a part of the impurities in the detergent to be caught by the blocking structure 12, reducing the possibility of impurities entering the liquid guide pipeline 11; on the other hand, the detergent can enter the internal space of the liquid guide pipeline 11 through the gap 1a, which can reduce the influence of the blocking structure 12 on the extraction of the detergent by the liquid guide pipeline 11, and ensure that the liquid guide pipeline 11 can extract enough detergent to meet the washing demand.

[0054] In the related art, the detergent in the detergent box is extracted through the opening of the first end of the liquid guide pipeline. When the distance between the end face of the first end of the liquid guide pipeline and the bottom wall of the detergent box is small, the air trapping phenomenon occurs, which makes it difficult for the liquid guide pipeline to suck in the detergent under the action of negative pressure. When the distance between the end face of the first end of the liquid guide pipeline and the bottom wall of the detergent box is large, when the liquid level of the remaining detergent in the detergent box is lower than the end face of the first end, the detergent cannot be sucked. At this time, the detergent box still has a lot of detergent that cannot be sucked. Therefore, in the related art, it is necessary to strictly control the manufacturing error of the liquid guide pipeline and the assembly error of the liquid guide pipeline and the detergent box, to ensure that the distance between the end face of the first end of the liquid guide pipeline and the bottom wall of the detergent box is within the designed preset range.

[0055] The detergent feeding device 1 in the embodiment of the application, the side wall of the first end 11b of the liquid guide pipeline 11 forms a liquid inlet groove 11a. In this way, regardless of the distance between the first end 11b of the liquid guide pipeline 11 and the bottom wall of the detergent box 10, the liquid guide pipeline 11 can extract the detergent through the liquid inlet groove 11a under the action of negative pressure, and the possibility of air trapping phenomenon of the liquid guide pipeline 11 when extracting the detergent can be reduced. Therefore, the requirement for the distance between the liquid guide pipeline 11 and the bottom wall of the detergent box 10 can be effectively reduced, and the manufacturing precision and assembly precision of the liquid guide pipeline 11 can be reduced.

[0056] The side wall of the first end 11b of the liquid guide pipeline 11 forms a liquid inlet groove 11a. The detergent in the detergent box 10 can enter the liquid guide pipeline 11 through the liquid inlet groove 11a, that is, the liquid inlet groove 11a penetrates the side wall of the liquid guide pipeline 11 in the thickness direction of the side wall of the liquid guide pipeline 11.

[0057] It should be noted that the specific shape of the liquid inlet groove 11a is not limited, which can be rectangular, circular, oval, etc.

[0058] The blocking structure 12 blocks at least part of the liquid inlet groove 11a. Wherein, the blocking structure 12 blocks at least part of the liquid inlet groove 11a means that the projection of the blocking structure 12 and the projection of the liquid inlet groove 11a exist an overlapping area on the normal projection of the plane or curved surface where the liquid inlet groove 11a is located. Of course, it can also be understood that, in the flow direction of the detergent flowing through the liquid inlet groove 11a, the blocking structure 12 blocks at least part of the liquid inlet groove 11a.

[0059] In some embodiments, please refer to Figure 2 , Figure 3 and Figure 9 , the liquid inlet groove 11a penetrates the end surface 11b1 of the first end of the liquid guide pipe 11. It can be understood that, on the one hand, the distance between the liquid inlet groove 11a and the bottom wall of the detergent box 10 is smaller, which is more conducive to the detergent at the bottom of the cavity 101 entering the liquid guide pipe 11 through the liquid inlet groove 11a, thereby improving the efficiency of the detergent dispensing device 1 to dispense detergent; on the other hand, it can facilitate the demolding of the liquid guide pipe 11 and improve the production efficiency.

[0060] Of course, in other embodiments, the liquid inlet groove 11a can also not penetrate the end surface 11b1 of the first end of the liquid guide pipe 11.

[0061] The number of liquid inlet grooves 11a is not limited, which can be one or more.

[0062] In some embodiments, please refer to Figure 2 and Figure 3 , the number of liquid inlet grooves 11a is multiple, and the multiple liquid inlet grooves 11a are arranged along the circumference of the liquid guide pipe 11. It can be understood that, by setting multiple liquid inlet grooves 11a, on the one hand, the demand for the flow rate of the liquid guide pipe 11 to extract detergent can be easily met; on the other hand, it is beneficial to reduce the size of a single liquid inlet groove 11a, thereby reducing the possibility of impurities entering the liquid guide pipe 11 through the liquid inlet groove 11a.

[0063] In some embodiments, please refer to Figure 4 and Figure 5 , the blocking structure 12 and the bottom wall of the detergent box 10 are an integral structure, for example, an integral injection molding part. That is, the blocking structure 12 can be integrally formed with the detergent box 10, which can improve the connection strength of the blocking structure 12 and the detergent box 10 on the one hand, and improve the manufacturing efficiency of the detergent dispensing device 1 on the other hand.

[0064] In the related art, an elastic valve plate or a screen is installed on the liquid guide pipeline to block foreign matters from entering the liquid guide pipeline, which is complex to assemble and has low production efficiency.

[0065] In the embodiments of the present application, the detergent box 10 and the blocking structure 12 are integrally formed, which can reduce the number of components of the detergent dispensing device 1, simplify the assembly process of the detergent dispensing device 1, save assembly procedures and time, and thus improve the production efficiency of the detergent dispensing device 1.

[0066] In other embodiments, the blocking structure 12 can be connected to the detergent box 10 by adhesion, welding, screws, or the like.

[0067] In some embodiments, please refer to Figure 5 , Figure 6 , Figure 8 and Figure 9 , the blocking structure 12 includes an outer blocking part 121, which is located at the outer periphery of the first end 11b of the liquid guide pipeline 11, and a gap 1a is formed between the outer blocking part 121 and the outer peripheral surface of the liquid guide pipeline 11. It can be understood that when the extraction mechanism operates, the detergent in the cavity 101 will flow to the liquid inlet groove 11a under the action of negative pressure. At this time, the outer blocking part 121 located at the outer periphery of the first end 11b of the liquid guide pipeline 11 can block the impurities carried in the detergent, and the detergent in a fluid state can flow into the liquid inlet groove 11a through the gap 1a. In this way, the outer blocking part 121 can not only block the impurities from entering the liquid guide pipeline 11, but also ensure that sufficient detergent can normally enter the liquid guide pipeline 11.

[0068] It should be noted that the specific number of the outer blocking part 121 is not limited.

[0069] Exemplarily, please refer to Figure 4 , Figure 5 , Figure 6 , Figure 8 and Figure 9 , the number of the liquid inlet grooves 11a is multiple, and in the embodiment in which the multiple liquid inlet grooves 11a are arranged at intervals along the circumference of the liquid guide pipeline 11, the number of the outer blocking parts 121 is multiple, and the multiple outer blocking parts 121 are arranged at intervals along the circumference of the liquid guide pipeline 11. At least one outer blocking part 121 is arranged on the outer side of each liquid inlet groove 11a. It can be understood that the interval between the adjacent two outer blocking parts 121 is beneficial to the detergent flowing into the liquid inlet groove 11a through the interval, increases the number of channels for the detergent flowing into the liquid guide pipeline 11, and is beneficial to the liquid guide pipeline 11 extracting sufficient detergent. On the other hand, the interval between the adjacent two outer blocking parts 121 can also intercept the impurities in the detergent, further reducing the possibility of the impurities entering the liquid guide pipeline 11.

[0070] In some embodiments, please refer toFigure 4 and Figure 5 At least part of the plurality of outer blocking portions 121 is located on the same circumference. It can be understood that when the circumference where the plurality of outer blocking portions 121 is located and the outer circumference of the liquid guide pipe 11 are located at the same center, the plurality of outer blocking portions 121 is facilitated to block the plurality of liquid inlet grooves 11a, and the interception capability of the outer blocking portion 121 for the detergent impurities is improved.

[0071] Of course, in other embodiments, the plurality of outer blocking portions 121 can also not be located on the same circumference.

[0072] It should be noted that the specific shape of the outer blocking portion 121 is not limited. In the embodiments of the present application, the outer blocking portion 121 is described by taking the outer blocking portion 121 in the form of a sheet as an example. The sheet-shaped outer blocking portion 121 can have a larger area to block the liquid inlet groove 11a, and is convenient for injection molding.

[0073] In some embodiments, please refer to Figure 3 , Figure 4 and Figure 5 The interval distance h3 between the two adjacent outer blocking portions 121 is less than the size h1 of the liquid inlet groove 11a in the circumferential direction of the liquid guide pipe 11, and is less than the size h2 of the liquid inlet groove 11a in the length direction of the liquid guide pipe 11.

[0074] It can be understood that when the detergent in the cavity 101 flows to the liquid inlet groove 11a, it will flow between the two adjacent outer blocking portions 121. At this time, the interval distance between the two adjacent outer blocking portions 121 can limit the size of the impurities in the detergent, and the impurities in the detergent can be intercepted by the two adjacent outer blocking portions 121, further reducing the impurities in the detergent entering the liquid guide pipe 11.

[0075] It should be noted that the interval distance h3 between the two adjacent outer blocking portions 121 refers to the shortest distance between the outer edges of the two adjacent outer blocking portions 121.

[0076] In some embodiments, please refer to Figure 4 , Figure 5 , Figure 6 , Figure 8 and Figure 9 The blocking structure 12 includes an inner blocking portion 122, and the first end 11b of the liquid guide pipe 11 is covered by the outer circumference of the inner blocking portion 122, that is, the inner blocking portion 122 extends into the inside of the liquid guide pipe 11. The inner blocking portion 122 blocks at least part of the liquid inlet groove 11a, and a gap 1a for the flow of the detergent is formed between the inner blocking portion 122 and the inner circumferential surface of the liquid guide pipe 11.

[0077] It can be understood that after the liquid guide pipe 11 is assembled, the internal blocking portion 122 is located inside the liquid guide pipe 11, so that the detergent can enter the liquid guide pipe 11 through the gap 1a formed by the internal blocking portion 122 and the inner surface of the liquid guide pipe 11 and / or the part of the internal blocking portion 122 that does not block the liquid inlet groove 11a. In this way, while ensuring the blocking effect of the internal blocking portion 122 on impurities, the liquid guide pipe 11 can normally extract the detergent in the cavity 101, which can not only reduce the impurities entering the liquid guide pipe 11 from the cavity 101, but also enable the liquid guide pipe 11 to extract enough detergent through the gap 1a.

[0078] It should be noted that the specific shape of the inner blocking portion is not limited.

[0079] For example, please refer to Figure 4 、 Figure 5 、 Figure 6 、 Figure 8 and Figure 9 The inner blocking portion 122 is in the shape of a hollow cylinder. It is understandable that the hollow cylindrical inner blocking portion 122 is convenient for shielding the liquid inlet groove 11a inside the liquid guiding pipe 11 and is also convenient for injection molding.

[0080] In some embodiments, please refer to Figure 2 、 Figure 3 、 Figure 6 、 Figure 8 and Figure 9 The dimension of the gap 1a in the thickness direction of the side wall of the catheter 11 is ( Figure 9 The h5 or h4 shown is smaller than the circumferential dimension h1 of the liquid inlet groove 11a in the liquid guiding pipe 11, and / or the dimension h5 or h4 of the gap 1a in the thickness direction of the side wall of the liquid guiding pipe 11 is smaller than the dimension h2 of the liquid inlet groove 11a in the length direction of the liquid guiding pipe 11. It can be understood that limiting the size of the gap 1a (h5 or h4) can ensure the normal passage of detergent while reducing the probability that the blocking structure 12 will reduce the blocking effect on impurities due to the excessive size of the gap 1a. In addition, by utilizing the relationship between the size of the gap 1a (h5 or h4) and the size of the liquid inlet groove 11a, the possibility of impurities in the detergent being stuck in the liquid inlet groove 11a after passing through the gap 1a can be reduced, and the possibility of the liquid inlet groove 11a being blocked can be reduced, which is conducive to ensuring the passability of the liquid inlet groove 11a to the detergent passing through the gap 1a, so as to maintain the normal extraction of detergent by the detergent dispensing device 1.

[0081] In the embodiment with the outer blocking portion 121, the dimension of the gap 1a in the thickness direction of the side wall of the catheter tube 11 refers to the distance between the surface of the outer blocking portion 121 close to the catheter tube 11 and the outer peripheral surface of the catheter tube 11, that is, Figure 9 h4 shown.

[0082] In the embodiment having the inner barrier portion 122, the size of the gap 1a in the thickness direction of the side wall of the catheter tube 11 refers to the distance between the surface of the inner barrier portion 122 on the side close to the catheter tube 11 and the inner peripheral surface of the catheter tube 11, that is, Figure 9 h5 is shown.

[0083] The above technical solutions include the following: First, the size (h5 or h4) of the gap 1a in the thickness direction of the side wall of the catheter tube 11 is smaller than the size h1 of the liquid inlet groove 11a in the circumferential direction of the catheter tube 11; second, the size (h5 or h4) of the gap 1a in the thickness direction of the side wall of the catheter tube 11 is smaller than the size h2 of the liquid inlet groove 11a in the length direction of the catheter tube 11; third, the size (h5 or h4) of the gap 1a in the thickness direction of the side wall of the catheter tube 11 is smaller than the size of the liquid inlet groove 11a in the length direction of the catheter tube 11, and the size (h5 or h4) of the gap 1a in the thickness direction of the side wall of the catheter tube 11 is smaller than the size of the liquid inlet groove 11a in the circumferential direction of the catheter tube 11.
