[0047] Most current detergent boxes are equipped with a siphon structure. When water is added to the detergent box and mixed with detergent, the mixed liquid of water and detergent can be discharged into the washing tub through the siphon structure to produce a siphon effect when it reaches a certain liquid level, and then be used for washing clothes. However, the existing siphon structure will leave a certain amount of detergent inside the detergent box after the mixed liquid is added, resulting in the detergent not being fully released into the washing tub. Moreover, after the detergent is left for a long time, it will produce odor or mold, thus affecting the user experience.

[0048] In order to solve the problem of detergent residue inside the detergent box, the present application proposes a detergent dispensing device and a clothing processing device having the detergent dispensing device. The clothing processing device can be a washing machine, a washing and drying machine, or other clothing processing devices with a laundry function. For the convenience of description, the present application only takes the clothing processing device as a drum washing machine as an example for illustration. Among them, by providing a negative pressure generator in the detergent dispensing device and connecting the negative pressure generator to the detergent chamber in the detergent box, the detergent in the detergent chamber can flow out to the outside of the detergent chamber under the negative pressure generated by the negative pressure generator, thereby reducing the detergent residue in the detergent chamber, improving the cleanliness of the detergent chamber, and reducing the generation of odor or mold.

[0049] Combination Figures 1 to 6 As shown, in some embodiments of the present application, the detergent dispensing device 1 includes a detergent box 10, a siphon assembly 20 and a negative pressure generator 30, the detergent box 10 is formed with at least one detergent chamber, the siphon assembly 20 is arranged in the detergent chamber, the siphon assembly 20 is formed with a siphon channel 23 for connecting the detergent chamber and the outside of the detergent box 10, and the negative pressure generator 30 is connected to the liquid outlet 232 of the siphon channel 23.

[0050] In some embodiments of the present application, the detergent box 10 may include one or more detergent chambers, and the detergent chambers may be used to store liquid detergent or solid detergent. Among them, liquid detergent may include detergent, softener, bactericide, care agent and other commonly used preparations, and solid detergent may include washing powder, washing gel and washing beads. Figure 1 As shown, in some embodiments of the present application, the detergent box 10 includes a first detergent chamber 11 and a second detergent chamber 12, and the first detergent chamber 11 and the second detergent chamber 12 can be used to store different types of liquid detergents, respectively. The liquid detergent is generally provided with a siphon assembly 20, by injecting water into the detergent chamber containing the liquid detergent and mixing it with the detergent, when the mixed liquid of the detergent and water reaches a certain liquid level, the siphon assembly 20 can automatically pump the mixed liquid in the detergent chamber to the outside of the detergent chamber. The detergent chamber in the present application refers to a liquid detergent chamber for storing liquid detergent, including the first detergent chamber 11 and the second detergent chamber 12.

[0051] In some other embodiments of the present application, the detergent box 10 further includes a solid detergent chamber 13 for storing solid detergent, and the solid detergent chamber 13 is generally not provided with a siphon assembly 20, and water can be directly injected into the solid detergent chamber 13 to impact the solid detergent, and the dissolved solid detergent can be directly transported to the outside of the solid detergent chamber 13. In some other embodiments of the present application, a siphon assembly 20 can also be provided in the solid detergent chamber 13, and the dissolved solid detergent can be transported to the outside of the solid detergent chamber 13 through the siphon assembly 20.

[0052] In some embodiments of the present application, the siphon assembly 20 includes a siphon tube 21 and a siphon cap 22. Openings 211 are respectively provided at both ends of the siphon tube 21 in the axial direction. The siphon cap 22 is covered on the outside of the top opening 211 of the siphon tube 21. A siphon channel 23 connecting the detergent chamber and the outside of the detergent box 10 is formed inside the siphon tube 21 and between the siphon cap 22 and the siphon tube 21. A liquid inlet 231 of the siphon channel 23 is formed between the bottom of the siphon cap 22 and the siphon tube 21, and a liquid outlet 232 of the siphon channel 23 is formed at the bottom opening of the siphon tube 21.

[0053] Combination Figures 1 to 6 As shown, in some embodiments of the present application, a siphon assembly 20 is provided in the first lotion chamber 11 and the second lotion chamber 12, respectively, and the lotion in the lotion chamber is pumped to the outside of the lotion chamber through the siphon assembly 20. The first lotion chamber 11 and the second lotion chamber 12 are respectively connected to the same negative pressure generator 30 through the siphon assembly 20 inside themselves. In some other embodiments of the present application, only one of the first lotion chamber 11 and the second lotion chamber 12 can be connected to the negative pressure generator 30, or more liquid lotion chambers can be connected to the same negative pressure generator 30, or each liquid lotion chamber is connected to a negative pressure generator 30. For the convenience of description, in the embodiments of the present application, only the first lotion chamber 11 is connected to the negative pressure generator 30 as an example for illustration.

[0054] The negative pressure generator 30 can generate negative pressure in the working state. Since the negative pressure generator 30 is connected to the liquid outlet 232 of the siphon channel 23, the detergent in the first detergent chamber 11 can flow out of the first detergent chamber 11 through the liquid outlet 232 of the siphon channel 23 under the negative pressure generated by the negative pressure generator, thereby reducing the residual detergent in the first detergent chamber 11, improving the cleanliness of the first detergent chamber 11, and reducing the generation of odor or mold. Figure 6 The direction indicated by the black straight arrow is the direction of lotion flow in the lotion chamber.

[0055] Combination Figures 1 to 6As shown, in some embodiments of the present application, the detergent box 10 further includes a water inlet connected to the detergent chamber, and the water inlet can be connected to an external water supply unit, so that water is injected into the first detergent chamber 11 through the water inlet. When the mixed liquid of detergent and water in the first detergent chamber 11 reaches a certain liquid level, a siphon effect can be generated through the siphon assembly 20, so as to be discharged to the outside of the first detergent chamber 11. The mixed liquid remaining in the first detergent chamber 11 is pumped to the outside of the first detergent chamber 11 under the action of the negative pressure generator 30.

[0056] Combination Figures 1 to 6 As shown, in some embodiments of the present application, since the negative pressure generated by the negative pressure generator 30 can directly pump the detergent in the first detergent chamber 11 to the outside, the water inlet structure in the original detergent box 10 can be omitted. There is no need to inject water into the first detergent chamber 11, and the detergent in the first detergent chamber 11 can be discharged to the outside of the first detergent chamber 11 only by the negative pressure of the negative pressure generator 30.

[0057] Combination Figures 1 to 7 As shown, in some embodiments of the present application, the negative pressure generator 30 includes a flow guide tube 31, which includes a first lumen segment 311, a second lumen segment 312 and a third lumen segment 313 which are connected in sequence, wherein, along a direction perpendicular to the axial direction of the flow guide tube 31, the cross-sectional area of ​​the second lumen segment 312 is respectively smaller than the cross-sectional area of ​​the first lumen segment 311 and the cross-sectional area of ​​the third lumen segment 313, and the liquid outlet 232 is connected to the second lumen segment 312.

[0058] By arranging the first lumen section 311, the second lumen section 312 and the third lumen section 313 according to the above structure, the interior of the flow guide tube 31 forms a structure similar to a Venturi tube, and can produce a Venturi effect accordingly. The Venturi effect refers to the increase in fluid velocity and the decrease in static pressure at a narrow part of a pipe when the fluid passes through the narrow part of the pipe, thereby generating a negative pressure.

[0059] Since the cross-sectional area of ​​the second tube cavity section 312 is respectively smaller than the cross-sectional area of ​​the first tube cavity section 311 and the cross-sectional area of ​​the third tube cavity section 313, by connecting the liquid outlet 232 with the second tube cavity section 312, when a fluid flows in the flow guide tube 31, under the effect of the Venturi effect in the flow guide tube 31, the lotion in the first lotion cavity 11 can enter the second tube cavity section 312 through the siphon channel 23 in sequence, thereby reducing the amount of lotion remaining in the first lotion cavity 11, improving the cleanliness of the first lotion cavity 11, and reducing the generation of odor or mold. The fluid can flow through the first tube cavity section 311, the second tube cavity section 312 and the third tube cavity section 313 in sequence, or the fluid can also flow through the third tube cavity section 313, the second tube cavity section 312 and the first tube cavity section 311 in sequence.

[0060] Combination Figures 1 to 7 As shown, in some embodiments of the present application, the guide tube 31 is arranged outside the detergent box 10, and the first detergent chamber 11 and the second detergent chamber 12 are respectively connected to the second tube cavity section 312 of the guide tube 31 through the siphon channel 23 inside each. Wherein, both ends of the guide tube 31 can be opened respectively, when the washing drum of the clothing processing device rotates, the clothing processing chamber in the washing drum generates air flow, and accelerates the air flow inside the clothing processing device. When the flowing airflow passes through the inside of the guide tube 31, a Venturi effect can be generated inside the guide tube 31, so as to pump the mixed liquid remaining at the bottom of the first detergent chamber 11 to the outside of the detergent box 10, thereby reducing the detergent residue in the first detergent chamber 11.

[0061] Combination Figures 1 to 7 As shown, in some embodiments of the present application, one end of the guide tube 31 may also be connected to the water inlet pipe, and water is injected into the guide tube 31 through the water inlet pipe. When the water flows inside the guide tube 31, a Venturi effect can be generated inside the guide tube 31, thereby pumping the detergent stored in the first detergent chamber 11 to the outside of the first detergent chamber 11, thereby reducing the residual detergent in the first detergent chamber 11.

[0062] In some other implementations of the present application, the guide tube 31 may also be disposed at the inner bottom of the detergent box 10 and connected to the siphon channel 23 and the washing drum through a pipeline.

[0063] In order to facilitate the connection between the siphon channel 23 and the second tube cavity section 312, in some embodiments of the present application, the lotion dispensing device 1 also includes a connecting pipe 40, which is arranged outside the lotion box 10, one end of the connecting pipe 40 is connected to the liquid outlet 232, and the other end of the connecting pipe 40 is connected to the second tube cavity section 312, so as to connect the first lotion cavity and the second tube cavity section 312. Among them, the axis of the connecting pipe 40 is perpendicular to the axis of the second tube cavity section 312, so as to improve the pumping efficiency of the guide tube 31. The connecting pipe 40 can be an integrated structure with the lotion box 10 and connected to the guide tube 31, and the specific connection method can be gluing or welding. Alternatively, the connecting pipe 40 can be a split structure with the lotion box 10 and fixedly connected to the lotion box 10. Alternatively, the connecting pipe 40 can be a split structure with the lotion box 10 and connected to the lotion box 10 in a detachable manner. When the flow guide tube 31 is needed to absorb the lotion in the first lotion chamber 11, it can be connected to the liquid outlet 232 through the connecting tube 40, so that the flow guide tube 31 and the lotion box 10 form a lotion delivery device 1, and the residual liquid in the first lotion chamber 11 is pumped to the outside of the first lotion chamber 11 through the flow guide tube 31. When the flow guide tube 31 is not needed to absorb the lotion in the first lotion chamber 11, the connecting tube 40 and the flow guide tube 31 can be removed, and the lotion box 10 only discharges the lotion through the siphon assembly 20.

[0064] Combination Figures 1 to 7 As shown, in some embodiments of the present application, the flow area of ​​the first tubular lumen segment 311 gradually decreases along the direction from the first tubular lumen segment 311 to the second tubular lumen segment 312, and the flow area of ​​the third tubular lumen segment 313 gradually increases along the direction from the second tubular lumen segment 312 to the third tubular lumen segment 313.

[0065] Through the above-mentioned structural setting, the flow area of ​​the first tubular lumen segment 311 is gradually reduced and the flow area of ​​the third tubular lumen segment 313 is gradually increased along the direction from the first tubular lumen segment 311 to the third tubular lumen segment 313, thereby reducing the occurrence of airflow turbulence caused by the sudden change of the flow area of ​​the first tubular lumen segment 311 and the flow area of ​​the third tubular lumen segment 313.

[0066] Combination Figures 1 to 7 As shown, in some embodiments of the present application, the guide tube 31 also includes at least one fourth lumen segment 314, the fourth lumen segment 314 is a straight tube segment, the fourth lumen segment 314 is provided at one end of the first lumen segment 311 away from the second lumen segment 312, and / or the fourth lumen segment 314 is provided at one end of the third lumen segment 313 away from the second lumen segment 312.

[0067] By providing the fourth tube cavity section 314 of the straight tube section, and arranging the fourth tube cavity section 314 at at least one end of the flow guide tube 31, it is possible to facilitate the connection of the flow guide tube 31 with other pipelines. For example, when the medium used to circulate in the flow guide tube 31 is water, the flow guide tube 31 can be connected to the water inlet pipe through the fourth tube cavity section 314, and water is injected into the interior of the flow guide tube 31 through the water inlet pipe. During the flow of water in the flow guide tube 31, negative pressure can be generated at the second tube cavity section 312, so as to suck the lotion in the first lotion cavity 11 into the second tube cavity section 312, thereby reducing the residual lotion in the first lotion cavity 11. Figure 7 As shown, the two ends of the flow guide tube 31 are respectively provided with a fourth lumen section 314, so the flow guide tube 31 can be connected to the water inlet pipe through the fourth lumen section 314 at either end. In some other embodiments of the present application, the fourth lumen section 314 can also be provided at only one end of the flow guide tube 31.

[0068] Combination Figures 1 to 7 As shown, in some embodiments of the present application, along a direction perpendicular to the axial direction of the guide tube 31, any cross-section of the guide tube 31 is a circular surface, and the diameter size of the cross-section of the second lumen segment 312 is smaller than the diameter size of the cross-section of the first lumen segment 311 and the diameter size of the cross-section of the third lumen segment 313, respectively.

[0069] In some embodiments of the present application, the first lumen segment 311 is a tapered segment, and the diameter of the first lumen segment 311 gradually decreases toward the second lumen segment 312, and the third lumen segment 313 is a tapered segment, and the diameter of the third lumen segment 313 gradually decreases toward the second lumen segment 312, so that the cross-sectional area of ​​the second lumen segment 312 is respectively smaller than the cross-sectional area of ​​the first lumen segment 311 and the cross-sectional area of ​​the third lumen segment 313. The second lumen segment 312 can be a straight segment, and the axial length of the second lumen segment 312 is greater than the lengths of the first lumen segment 311 and the third lumen segment 313, so that the second lumen segment 312 is connected to the first lotion cavity 11 and the second lotion cavity 12 at the same time.

[0070] Combination Figures 1 to 6 As shown, in some embodiments of the present application, the lotion dispensing device 1 further includes a throttle valve (not shown in the figure), and a throttle valve is provided inside the flow guide tube 31; and / or a throttle valve is provided inside the connecting tube 40.

[0071] By setting a throttle valve and controlling the opening or closing of the throttle valve, the connection or disconnection between the flow guide tube 31 and the liquid outlet 232 can be controlled. When the throttle valve is arranged inside the flow guide tube 31, by controlling the opening or closing of the throttle valve, the generation and disappearance of the Venturi effect in the flow guide tube 31 can be controlled, thereby simultaneously controlling the extraction of the residual liquid in the first lotion chamber 11 and the second lotion chamber 12. When the throttle valve is arranged on the connecting pipe 40 connecting the flow guide tube 31 and the lotion chamber, the connection or disconnection between the first lotion chamber 11 and the flow guide tube 31 can be controlled separately, and / or the connection or disconnection between the second lotion chamber 12 and the flow guide tube 31 can be controlled separately. For example, a throttle valve is respectively provided on the connecting tube 40 between the first lotion chamber 11 and the flow guide tube 31 and on the connecting tube 40 between the second lotion chamber 12 and the flow guide tube 31. When it is necessary to extract the lotion in the first lotion chamber 11, the throttle valve on the connecting tube 40 between the first lotion chamber 11 and the flow guide tube 31 is switched to an open state, and the throttle valve on the connecting tube 40 between the second lotion chamber 12 and the flow guide tube 31 is switched to a closed state. The flow guide tube 31 is connected to the first lotion chamber 11, and the lotion in the first lotion chamber 11 can flow into the flow guide tube 31 through the siphon channel 23, while the flow guide tube 31 and the second lotion chamber 12 are in a disconnected state, and the lotion in the second lotion chamber 12 cannot flow out, thereby realizing the separate addition control of the lotion in different lotion chambers.

[0072] In some embodiments of the present application, the negative pressure generator 30 may further include a liquid pump. The liquid pump is directly connected to the first lotion chamber 11 and / or the second lotion chamber 12, and the lotion in the first lotion chamber 11 and / or the second lotion chamber 12 is directly pumped to the outside through the negative pressure generated when the liquid pump is running, thereby reducing the residual lotion.

[0073] Combination Figures 1 to 8 As shown, the second aspect of the present application proposes a clothing processing device 100, and the clothing processing device 100 has a detergent dispensing device 1 of any of the above-mentioned embodiments.

[0074] The clothing processing device 100 may be a washing machine, a washer-dryer, or other clothing processing device with a washing function. For the convenience of description, this application only takes the clothing processing device 100 as a drum-type washing machine as an example for illustration. Among them, by providing a negative pressure generator 30 in the detergent dispensing device 1 of the clothing processing device 100, and connecting the negative pressure generator 30 with the detergent cavity in the detergent box 10, the detergent in the detergent cavity can flow out to the outside of the detergent cavity under the negative pressure generated by the negative pressure generator 30, thereby reducing the detergent residue in the detergent cavity, improving the cleanliness of the detergent cavity, and reducing the generation of odor or mold.

[0075] Among them, the clothing processing device 100 includes a housing 2, which forms the appearance structure of the clothing processing device 100, and is provided with an installation cavity inside the housing, and the installation cavity is used to install a washing drum and various components. The washing drum is arranged in the installation cavity, and the washing drum is arranged in the horizontal direction or at an angle to the horizontal direction. A clothing processing cavity is provided inside the washing drum, which is used to store clothing so as to wash the clothing. A loading port 3 connected to the clothing processing cavity is provided at the front end of the washing drum, and a door body 4 is also connected to the front end of the housing 2. By operating the door body 4, the loading port 3 can be opened or closed, so that the clothing can be put into the clothing processing cavity through the loading port 3, and then the clothing can be washed. Specifically, the door body 4 is connected to the housing 2 in a rotatable manner.

[0076] Combination Figures 1 to 8 As shown, in some embodiments of the present application, the negative pressure generator 30 includes a flow guide pipe 31, which is connected to the clothing processing chamber of the clothing processing device 100; or, the clothing processing device 100 also includes a water inlet pipe, which is connected to the flow guide pipe 31.

[0077] In some embodiments of the present application, the negative pressure generator 30 includes a flow guide tube 31, which is connected to the clothing processing chamber of the clothing processing device 100. The two ends of the flow guide tube 31 can be opened respectively, and when the washing drum of the clothing processing device 100 rotates, airflow occurs in the clothing processing chamber in the washing drum, and the airflow inside the clothing processing device 100 is accelerated. When the flowing airflow passes through the inside of the flow guide tube 31, a Venturi effect can be generated inside the flow guide tube 31, so as to pump the detergent stored in the first detergent chamber 11 to the outside of the first detergent chamber 11, thereby reducing the residual detergent in the first detergent chamber 11.

[0078] In some embodiments of the present application, the negative pressure generator 30 includes a flow guide pipe 31, and the laundry processing device 100 further includes a water inlet pipeline, which is connected to the flow guide pipe 31. One end of the water inlet pipeline can be connected to an external water supply unit, and the other end of the water inlet pipeline can be connected to the flow guide pipe 31. Water is injected into the flow guide pipe 31 through the water inlet pipeline, so that the water flow generates negative pressure when flowing through the second tube cavity section 312, thereby pumping the detergent in the first detergent chamber 11 and / or the second detergent chamber 12 into the second tube cavity section 312, and finally discharged from the flow guide pipe 31. The water inlet pipeline can be used not only to inject water into the flow guide pipe 31, but also to inject water into the detergent chamber, thereby generating a siphon effect in the detergent chamber and discharging a mixed liquid of detergent and water; or, dissolving the solid detergent in the detergent chamber and discharging the dissolved solution into the washing tub.

[0079] The above is only a preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
