A detergent dispenser and a washing apparatus

Abstract

The application provides a detergent feeding device and a washing equipment, which comprises a distributor box and a detergent box. The detergent box is provided with a water mixing tank and a first water outlet which are communicated with each other. A circulating water joint is arranged on the detergent box. The circulating water joint comprises a circulating water channel and a circulating water standby channel which are communicated with each other. The outlet of the circulating water channel is used for guiding the water flow to the water inlet of the filter. The inlet of the circulating water channel is used for introducing the circulating water. The highest position of the circulating water standby channel is higher than that of the circulating water channel. A circulating pump is used for pumping the water with lint on the bottom of the outer tub to the inlet of the circulating water channel. The circulating water enters the filter through the circulating water channel, so that the lint is filtered. When the filter is blocked, the back pressure of the water outlet of the circulating water channel is increased, so that the circulating water flows to the circulating water standby channel and is discharged through the circulating water standby channel, thereby reducing the probability of the faults such as pipe explosion and damage to the circulating pump caused by the sharp increase of the water pressure.

[0054] The embodiments of the present application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the present application but cannot be used to limit the scope of the present application.

[0055] In the description of the embodiments of the present application, it should be noted that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only used for the purpose of facilitating the description of the embodiments of the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the embodiments of the present application. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0056] The embodiments of the present application provide a detergent dispensing device 100 for a washing apparatus, please refer to Figure 1 and Figure 2 , comprising a dispenser box 10 and a detergent box 20.

[0057] The embodiments of the present application also provide a washing apparatus, please refer to Figure 11 , Figure 12 and Figure 13 , comprising an inner cylinder 90, an outer drum 80, a circulating pump 61, a circulating pipeline 62 and the detergent dispensing device 100 of any embodiment of the present application.

[0058] The inner cylinder 90 is arranged in the outer drum 80, and the inner cylinder 90 is filled with water through the outer drum 80.

[0059] The specific type of the washing apparatus is not limited, for example, it can be a washing machine, a washing and drying all-in-one machine, etc.

[0060] The dispenser box 10 has a mounting space for mounting the filter 31. The filter 31 is mounted in the mounting space. The specific type of the mounting space is not limited, for example, in some embodiments, please refer to Figure 10 , the mounting space is configured in the form of a containing groove 10a, and the filter 31 is arranged in the containing groove 10a.

[0061] Please refer to Figure 3 and Figure 12 , the detergent box 20 has a pull-out space 20a, and the dispenser box 10 is pullably arranged in the pull-out space 20a in the detergent box 20. Please refer to Figure 1The dispenser box 10 is in the state of being pulled out of the pull space 20a. During normal use of the washing apparatus, the dispenser box 10 is pushed into the pull space 20a.

[0062] Referring to Figure 6 and Figure 9 The detergent box 20 has a water mixing tank 21a and a first water outlet 21b in communication with each other, and the first water outlet 21b is used to discharge water in the water mixing tank 21a. Specifically, the water mixing tank 21a is located at the lower part of the pull space 20a. The detergent and water flow to the water mixing tank 21a, and the water flow carries the detergent to be discharged from the first water outlet 21b.

[0063] Referring to Figure 13 and Figure 14 The detergent box 20 is provided with a circulating water joint 24, which includes a circulating water passage 241a and a circulating water standby passage 242a in communication with each other. The outlet of the circulating water passage 241a is used to guide the water flow to the water inlet of the filter 31 in the dispenser box 10, and the inlet of the circulating water passage 241a is used to introduce the circulating water. Specifically, the circulating pump 61 is used to pump the water in the outer tub 80 to the inlet of the circulating water passage 241a through the circulating pipeline 62.

[0064] The circulating pump 61 pumps the water with the lint at the bottom of the outer tub 80 to the inlet of the circulating water passage 241a, and the circulating water enters the filter 31 through the circulating water passage 241a. After flowing through the filter 31, the lint is left in the filter 31, and the filtered water flows out of the water outlet of the filter 31 to achieve the purpose of circulating and filtering the lint.

[0065] The highest position of the circulating water standby passage 242a is higher than that of the circulating water passage 241a. In this way, after the water flow enters the circulating water passage 241a from the inlet of the circulating water passage 241a, the resistance of the water flow to the filter 31 through the circulating water passage 241a is smaller than that to the circulating water standby passage 242a. Therefore, in the normal use state, the circulating water preferentially flows to the filter 31 through the circulating water passage 241a.

[0066] When the filter 31 is blocked, the back pressure of the water outlet of the circulating water passage 241a increases, forcing the circulating water to flow to the circulating water standby passage 242a and be discharged through the circulating water standby passage 242a. As can be seen, the circulating water standby passage 242a plays a safety precaution role, which can timely discharge the water in the circulating pipeline 62 when the filter 31 is blocked, reducing the probability of pipe explosion, damage to the circulating pump 61 and other faults caused by the sharp increase of water pressure.

[0067] Exemplarily, referring to Figure 10The dispenser box 10 has a plurality of accommodation grooves 10a, 10b, one of which 10a is used to place the filter 31, and the rest 10a, 10b are used to accommodate detergent bottles 32.

[0068] For example, referring to Figure 1 and Figure 10 , the plurality of accommodation grooves 10a, 10b are arranged side by side in the left-right direction.

[0069] The detergent bottles 32 can contain laundry detergent, softener, disinfectant, perfume, etc. In embodiments with multiple detergent bottles 32, each detergent bottle 32 contains a different type of detergent.

[0070] For example, the washing machine includes a door body, a cabinet, and a door seal ring 50 arranged at the front end of the inner tub 90, and the outer tub 80 is arranged in the cabinet. The cabinet is provided with an opening, and the door body is used to open or close the opening. The door seal ring 50 is used to seal the gap between the outer tub 80 and the opening of the cabinet, and when the door body closes the opening, the door body sealingly abuts on the door seal ring 50.

[0071] For example, referring to Figure 11 and Figure 13 , the door seal ring 50 has a water inlet 50a. Referring to Figure 12 and Figure 13 , the washing machine includes a first water outlet pipeline 71, which communicates the first drain 21b and the water inlet 50a. That is, the water in the mixing tank 21a is injected into the inner tub 90 through the first drain 21b and the water inlet 50a of the door seal ring 50, so that the detergent is directly injected into the inner tub 90 and directly contacts the clothes, improving the utilization rate of the detergent.

[0072] For example, in some embodiments, the inner tub 90 is provided with a lifting rib. The inner tub 90 has a water passing hole in the area covered by the lifting rib, and no water passing hole outside the area covered by the lifting rib. The water exchange between the inner tub 90 and the outer tub 80 is through the water passing hole. In this embodiment, the clothes will not contact the hole edge of the water passing hole, which can reduce the wear of the clothes by the hole edge of the water passing hole. In this embodiment, the water directly enters the inner tub 90, and the water injected into the inner tub 90 slowly passes through the water hole into the outer tub 80, so that the clothes can be soaked as soon as possible, improving the washing efficiency.

[0073] For example, the mixing tank 21a is used to contain the filtered water filtered by the filter 31. That is, the water filtered by the filter 31 directly flows to the mixing tank 21a below the filter 31, without the need to set an additional pipeline to drain water, and the first drain 21b can be used for drainage, so that the structure can be simplified, and the detergent dispenser 100 is more simple in structure.

[0074] It should be noted that the water outlet of the circulating water standby passage 242a can direct the water flow to any suitable position. For example, in some embodiments, the water outlet of the circulating water standby passage 242a is directly connected to the outer tub 80 through a pipeline.

[0075] In some other embodiments, the water outlet of the circulating water standby passage 242a is communicated with the water mixing tank 21a, that is, the water mixing tank 21a is also used to receive water from the circulating water standby passage 242a. In this way, no additional pipeline is needed to connect the water outlet of the circulating water standby passage 242a, and the first drain port 21b can be reused for draining. In this way, the structure can be simplified, and the detergent dispenser 100 can be made simpler.

[0076] For example, referring to Figure 2 , the detergent box 20 includes a box body 21 and a box cover 22. The top side of the box body 21 is open, and the box cover 22 is arranged on the open top side of the box body 21. The box body 21 and the box cover 22 together define a pulling space 20a for accommodating the dispenser box 10.

[0077] For example, referring to Figure 6 , the water mixing tank 21a is arranged in the box body 21.

[0078] For example, the water outlet of the circulating water passage 241a is arranged on the box body 21, and the water outlet of the circulating water standby passage 242a is arranged on the box cover 22. In this way, the water outlet of the circulating water standby passage 242a and the water outlet of the circulating water passage 241a have a height difference, which generates a corresponding water outlet back pressure, so that the water outlet priority of the circulating water passage 241a is higher than that of the circulating water standby passage 242a.

[0079] For example, referring to Figure 11 and Figure 13 , the circulating water connector 24 is arranged at the rear of the detergent box 20. The circulating water connector 24 includes a main pipeline 241 and a branch pipeline 242 connected to each other. The main pipeline 241 is arranged in the front-rear direction. The rear end of the main pipeline 241 is used to connect the circulating pipeline 62, and the front end of the main pipeline 241 is used to pluggably mate with the water inlet of the filter 31.

[0080] For example, referring to 3, the rear wall of the box body 21 is provided with a relief opening 21h, and the front end of the main pipeline 241 extends into the interior of the box body 21 through the relief opening 21h.

[0081] The flow passage in the main pipeline 241 defines the above-mentioned circulating water passage, and the space in the branch pipeline 242 defines the above-mentioned circulating water standby passage 242a.

[0082] When the dispenser box 10 is pulled out, the front end of the main pipe 241 is separated from the filter 31, and when the dispenser is pushed into place, the front end of the main pipe 241 and the filter 31 are plugged into place.

[0083] The top wall of the box cover 22 is provided with a circulating water standby interface 22a, one end of the branch pipe 242 is connected with the main pipe 241, for example, a tee joint is arranged at the connection of the two. The other end of the branch pipe 242 is arranged from the rear of the box body 21 to the top side of the box cover 22 and is connected with the circulating water standby interface 22a. In this way, the branch pipe 242 does not occupy space in the detergent box 20, facilitating pipe arrangement and making the structure of the detergent box 20 compact.

[0084] It should be noted that the main pipe 241 can be a complete pipe or a plurality of sectional pipes connected together.

[0085] The branch pipe 242 can be a complete pipe or a plurality of sectional pipes connected together.

[0086] Exemplarily, please refer to Figure 6 , Figure 7 and Figure 8 , the rear wall of the box body 21 is provided with an air pressure balance port 21g. The outer tub 80 has a vent. The washing device comprises an air pressure balance pipe which communicates the vent and the air pressure balance port 21g. The space in the outer tub is kept in air pressure balance with the space in the detergent box through the air pressure balance pipe, and the space in the detergent box is communicated with the external environment, so the air pressure in the detergent box is the same as the atmospheric pressure outside, thereby achieving air pressure balance between the outer tub and the external environment.

[0087] It should be noted that if the outer tub does not have a vent, the space in the outer tub is in a relatively closed state and has a certain air pressure, which will generate a certain back pressure on the outer tub and / or the inner tub during water filling, resulting in failure to fill water or slow water filling.

[0088] The specific position of the air pressure balance port 21g can be designed according to actual needs.

[0089] Exemplarily, please refer to Figure 14 , the air pressure balance port 21g is located approximately below the circulating water standby interface 22a.

[0090] Exemplarily, please refer to Figure 4 and Figure 5 , the bottom side of the box cover 22 is provided with a water guide 221, and the top end of the water guide 221 is connected with the top wall of the box cover 22. The water guide 221 is used to guide the water of the circulating water standby interface 22a to the bottom wall of the box body 21, and the water flows along the bottom wall of the box body 21 to the mixed water tank 21a.

[0091] The water guide 221 guides the water flow, reduces the impact of the water flow on the bottom wall of the box body 21, and reduces the noise caused by the water flow. In addition, the water splashing degree can also be reduced.

[0092] For example, referring to Figure 3 , the bottom end of the water guide 221 is spaced apart from the bottom wall of the box body 21. In this way, during the assembly of the box cover 22 and the box body 21, the bottom end of the water guide 221 will not interfere with the box body 21.

[0093] For example, the box cover 22 is an integrally formed injection molded part, that is, the water guide 221, the top wall of the box cover 22, and the remaining parts are integrally injection molded. For example, the water guide 221 is located at the rear of the dispenser box 10. The water guide 221 does not interfere with the dispenser box 10, and can fully utilize the space behind the dispenser box 10.

[0094] It should be noted that the water guide 221 cannot interfere with the plug-in cooperation of the main pipeline 241 and the filter 31, and cannot interfere with the plug-in cooperation between the dispensing pump 40 and the detergent bottle 32.

[0095] For example, the water guide 221 is located at the right rear corner of the detergent box. In this way, the water guide 221 can fully utilize the space of the right rear corner of the detergent box 20 and does not interfere with the dispenser box 10.

[0096] For example, referring to Figure 5 , the water guide 221 includes a first water blocking wall 2211, the front surface of the first water blocking wall 2211 is a water guide surface, and the first water blocking wall 2211 is located in front of the air pressure balance port 21g and blocks the air pressure balance port 21g. Wherein, referring to Figure 3 , in the planar projection perpendicular to the pulling direction of the dispenser box 10, the first water blocking wall 2211 blocks the air pressure balance port 21g.

[0097] In this embodiment, the first water blocking wall 2211 can block the water flow from splashing into the air pressure balance port 21g, and the splashing water in the detergent box 20 is not easy to splash from the air pressure balance port 21g to the outside of the detergent box 20, so that the joint part of the air pressure balance port and the air pressure balance pipeline is not easy to be water seepage.

[0098] The specific structure of the water guide 221 is not limited, for example, the water guide 221 is in the form of a sheet, and the water flows down the water guide surface on the front side of the first water blocking wall 2211. In some embodiments, the first water blocking wall 2211 gradually inclines forward in the downward direction, so that the water flow flows along the water guide surface. Of course, the water guide surface can also be inclined.

[0099] Exemplarily, the water guide 221 is in a flat tube shape. Specifically, referring to Figure 5 The water guide 221 comprises a second water blocking wall 2212, which is located at the front side of the first water blocking wall 2211, and the left end of the first water blocking wall 2211 is connected with the left end of the second water blocking wall 2212, and the right end of the first water blocking wall 2211 is connected with the right end of the second water blocking wall 2212, and the two define a flat water guide flow channel 221a, in which the water flows. In this way, the water flow can be better constrained and guided, and the influence of the water flow on other components can be reduced.

[0100] Exemplarily, referring to Figure 3 and Figure 5 , the bottom edge of the second water blocking wall 2212 is lower than the bottom edge of the first water blocking wall 2211.

[0101] In this embodiment, the length of the second water blocking wall 2212 is less than the length of the first water blocking wall 2211, which can reduce the cantilever length of the mold of the water guide 221, improve the stress condition of the mold, and improve the service life and reliability of the mold.

[0102] Exemplarily, referring to Figure 5 , the second water blocking wall 2212 is provided with an open slot 2212a, and the opening of the open slot 2212a is located at the bottom edge of the second water blocking wall 2212. The open slot 2212a extends substantially in the up-down direction. The open slot 2212a can also improve the stress condition of the mold. Specifically, the mold is provided with a core at the open slot 2212a, and the mold part corresponding to the first water blocking wall 2211 can be connected together, so that the mold part corresponding to the first water blocking wall 2211 can be avoided to be in a thin and long cantilever state, so that the stress condition of the mold can be improved, and the service life and reliability of the mold can be improved.

[0103] Exemplarily, referring to Figure 6 and Figure 9 , the bottom wall of the detergent box 20 is provided with a water blocking rib 211 and a second drain port 21d, and the water blocking rib 211 separates the lower space of the detergent box 20 into a water mixing tank 21a and a drain tank 21c. The second drain port 21d communicates with the drain tank 21c, and the second drain port 21d is used to drain the water in the drain tank 21c. That is to say, the first drain port 21b and the water mixing tank 21a are located on one side of the water blocking rib 211, and the second drain port 21d and the drain tank 21c are located on the other side of the water blocking rib 211.

[0104] Exemplarily, the washing appliance comprises a second water outlet pipeline 74, which guides the water flow discharged by the second drain port 21d to between the outer tub 80 and the inner tub 90.

[0105] It can be understood that the water flow cross-sectional area of the second drain port 21d is greater than that of the first drain port 21b. That is, under the condition of sufficient water volume, the water flow of the second drain port 21d is greater than that of the first drain port 21b.

[0106] When the water level in the mixing tank 21a is higher than the overflow level, the liquid in the mixing tank 21a overflows into the drain tank 21c.

[0107] In this embodiment, when the water level in the mixing tank 21a is not higher than the overflow level, the water in the mixing tank 21a flows into the first water outlet pipeline 71 from the first drain port 21b. When the water level in the mixing tank 21a is higher than the overflow level, the excess water overflows into the drain tank 21c and flows into the second water outlet pipeline 74 from the second drain port 21d. That is, the detergent dispensing device preferentially discharges water from the first drain port 21b.

[0108] Since the water of the first drain port 21b needs to be guided to the water inlet 50a of the door seal ring 50, the maximum water flow is limited by the water inlet 50a. The second drain port 21d and the drain tank 21c can timely guide the water flow in the detergent box 20 to the outer tub 80 in the overflow condition, which not only plays a safety protection role but also speeds up the water inlet.

[0109] The overflow level in the mixing tank 21a is determined by the structure of the water retaining rib 211. Specifically, the overflow level is the lowest water level corresponding to the water retaining rib 211 allowing the water in the mixing tank 21a to flow to the drain tank 21c.

[0110] Exemplarily, in some embodiments, the height of the top edge of the water retaining rib 211 serves as the overflow level of the mixing tank 21a. When the water level in the mixing tank 21a continuously rises to the top edge of the water retaining rib 211, the water overflows the water retaining rib 211, flows from the top side of the water retaining rib 211 to the drain tank 21c on the second side of the water retaining rib 211, and is discharged from the second drain port 21d.

[0111] In other embodiments, the water retaining rib 211 is provided with a notch, and the height of the bottom edge of the notch serves as the overflow level of the mixing tank 21a.

[0112] Exemplarily, please refer to Figure 7 , Figure 8 and Figure 9 , the detergent dispensing device 100 comprises a Venturi tube 23 arranged below the detergent box 20. Please refer to Figure 11 , the washing device comprises a water inlet pipeline 72, and the inlet 23a (refer to Figure 9 ) of the Venturi tube 23 is used to connect the water inlet pipeline 72, and the first drain port 21b is communicated to the negative pressure suction port 23c (refer to Figure 9); the first water outlet pipeline 71 is connected with the outlet 23b (refer to Figure 9 ) of the Venturi tube 23.

[0113] When water is filled, water from the water inlet pipeline 72 flows through the Venturi tube 23, and the water flow generates negative pressure at the negative pressure suction port 23c, and the water of the first water outlet port 21b is sucked into the Venturi tube 23 and flows into the first water outlet pipeline 71, and flows to the water injection port 50a of the door seal ring 50.

[0114] In this embodiment, the use of the Venturi tube 23 can accelerate the drainage speed of the water mixing tank 21a, so that as much water as possible in the water mixing tank 21a is drained from the first water outlet port 21b, that is, as much water mixed with detergent as possible can enter the inner drum 50 from the water injection port 50a of the door seal ring 50, and as little as possible overflow into the drain groove 21c.

[0115] Exemplarily, please refer to Figure 2 , the detergent dispensing device 100 comprises a dispensing pump 40, which is used to quantitatively extract the detergent in the dispenser box 10. It should be noted that the detergent in the dispenser box 10 can be the detergent directly stored in the accommodating cavity of the dispenser box 10, or the detergent placed in the detergent bottle 32 in the dispenser box 10.

[0116] In the embodiments of the present application, the extraction of the detergent in the detergent bottle 32 by the dispensing pump 40 is described as an example.

[0117] Please refer to Figure 3 and Figure 6 , at least one dispensing port 21f is arranged on the rear wall of the box body 21, wherein the number of the dispensing port 21f is consistent with the number of the suction ports of the dispensing pump 40 and consistent with the number of the detergent bottles 32. The detergent is extracted from the suction ports of the dispensing pump 40 into the dispensing pump 40, and is poured into the detergent box 20 from the dispensing port 21f.

[0118] Exemplarily, please refer to Figure 1 , Figure 2 and Figure 3 , at least one flushing port connector 22b is arranged on the top wall of the box cover 22, and the flushing port connector 22b is located above the dispensing port 21f. Please refer to Figure 11 , the washing equipment comprises at least one water inlet branch pipe 73, one end of each water inlet branch pipe 73 is in communication with the water inlet pipe, and the other end of the water inlet branch pipe 73 is connected with the corresponding flushing port connector 22b, and the flushing port connector 22b is used to guide the water of the water inlet branch pipe 73 to the inside of the detergent box 20.

[0119] When the water inlet pipe 72 is supplied with water, the water inlet pipe 72 is divided into multiple water paths, one of which flows to the Venturi tube 23 downstream of the water inlet pipe 72, and the other of which flows to the inside of the detergent box 20 through the water inlet branch pipe 73 and the flushing joint 22b, and flushes the detergent below the dispensing opening 21f to flow to the mixing tank 21a.

[0120] The water flowing from the flushing joint 22b has a flushing effect on the detergent, which helps to promote the dissolution of the detergent and reduces the probability of the detergent remaining on the inner wall of the box body 21 and the probability of bacterial growth.

[0121] Please refer to Figure 1 and Figure 2 The box cover 22 is provided with a hand-feeding water inlet channel 22c for introducing an external water source, and the water outlet of the hand-feeding water inlet channel 22c is located above the containing groove 10b, so that the water flow discharged therefrom can enter the dispenser box 10. That is, the water flow discharged from the hand-feeding water inlet channel 22c first flows to the inside of the dispenser box 10, and then flows to the mixing tank 21a from the dispenser box 10.

[0122] At least one containing groove 10b is used to contain a detergent bottle 32 or a hand-feeding box. That is, for the same containing groove 10a, 10b, either a detergent bottle 32 or a hand-feeding box is placed therein. The design of the detergent dispensing device 100 is interchangeable between a detergent container and a hand-feeding box.

[0123] The user manually feeds the hand-feeding box with the amount of detergent required for a single washing. When the hand-feeding box is placed in the containing groove 10b, the water inlet pipe 72 is connected to the water inlet of the hand-feeding water inlet channel 22c, and the water flow discharged from the hand-feeding water inlet channel 22c flows into the hand-feeding box and carries the detergent in the hand-feeding box to flow to the mixing tank 21a.

[0124] The detergent dispensing device 100 of this embodiment selectively configures a detergent bottle 32 or a hand-feeding box, and different configurations of washing equipment can use the same detergent dispensing device 100. When assembling, the water inlet pipe 72 can be connected to the water inlet of the hand-feeding water inlet channel 22c or to the inlet of the Venturi tube 23 according to the configuration of the detergent. In this way, the generalization rate of parts can be improved, the inventory pressure of idle materials can be reduced, the same mold can be used to manufacture the detergent dispensing device 100 for different configurations of washing equipment, the cost investment of the mold can be reduced, and the product development cycle can also be shortened.

[0125] For ease of description, the containing groove 10a for containing the filter 31 is referred to as a first containing groove 10a, and the remaining containing grooves 10b are referred to as second containing grooves 10b.

[0126] In the embodiment in which the number of the second accommodating grooves 10b is at least two, one of the second accommodating grooves 10b can accommodate the hand feeding box, and the other of the second accommodating grooves 10b can accommodate the detergent bottle 32; alternatively, all of the second accommodating grooves 10b can accommodate the detergent bottle 32; or alternatively, all of the second accommodating grooves 10b can accommodate the hand feeding box.
