Description

Technical Field

[0001] This application belongs to the field of washing machine technology, and particularly relates to a hybrid dispensing structure, dispensing components and washing machine. Background Technology

[0002] With the improvement of living standards, washing machines have become an indispensable household appliance for countless families. Currently, some washing machines on the market are equipped with a detergent premixing structure, which pre-mixes detergent and water before adding them to the inner drum, reducing detergent residue after washing. To further improve the premixing effect, one existing design uses a suction structure to extract air and the detergent mixture for secondary premixing, delivering the gas-liquid mixture to the inner drum. However, when the suction structure fails, the detergent mixture may overflow from the air intake. If this overflowing detergent mixture flows onto the washing machine's electrical components or the outside, it could pose a safety hazard or cause property damage to the user. Utility Model Content

[0003] This application provides a hybrid dispensing structure, dispensing components, and a washing machine, which can solve the technical problem that existing hybrid dispensing structures are prone to liquid overflowing from the gas flow port, causing safety hazards.

[0004] To achieve the above objectives, this application provides the following technical solution:

[0005] A hybrid dispensing structure is applied to a washing machine, the washing machine including a washing tub, the hybrid dispensing structure comprising:

[0006] The mixing chamber has a mixing chamber with a first liquid inlet, a second liquid inlet, and a liquid outlet. The first liquid inlet is suitable for conveying a laundry treatment agent, and the second liquid inlet is suitable for introducing water, so that the laundry treatment agent and water are mixed in the mixing chamber.

[0007] The negative pressure suction structure has an internal negative pressure chamber with a suction port, a return air port and a dispensing port. The suction port is connected to the liquid outlet. The return air port and the dispensing port are both used to connect to the washing tub. The negative pressure chamber draws the mixed liquid through the suction port and dispenses the mixed liquid into the washing tub through the dispensing port.

[0008] The air return port is used to draw air from the washing tub so that the mixture is mixed with air before being added to the washing tub, or to add the mixture overflowing from the negative pressure chamber to the washing tub.

[0009] In some embodiments, the negative pressure suction structure includes:

[0010] A venturi tube includes an inlet end forming the suction port, an outlet end forming the dispensing port, and a throat forming the negative pressure chamber, wherein the throat is provided with an opening;

[0011] The return pipe has one end connected to the opening and the other end forming the return air port.

[0012] In some embodiments, the mixing and dispensing structure further includes a one-way valve body disposed at the first liquid inlet to restrict the one-way flow of the clothing treatment agent in the first liquid inlet.

[0013] In some embodiments, the number of the first liquid inlets is at least two, and each of the first liquid inlets is used to deliver a clothing treatment agent with corresponding efficacy.

[0014] A dispensing component, applied to a washing machine, includes:

[0015] Laundry detergent dispenser, suitable for holding laundry detergent;

[0016] The aforementioned mixed delivery structure;

[0017] A dispensing pump is connected to the laundry detergent box and the first liquid inlet, and is used to pump the laundry detergent to the liquid inlet.

[0018] In some embodiments, the garment treatment agent box has a first chamber and a second chamber spaced apart, the first chamber being used to hold a first treatment agent and the second chamber being used to hold a second treatment agent; the number of the first liquid inlets is at least two; the dispensing pump has a first pumping channel and a second pumping channel, the first pumping channel connecting the first chamber and one of the first liquid inlets, and the second pumping channel connecting the second chamber and another of the first liquid inlets.

[0024] A control panel assembly is rotatably connected to the opening of the housing. The laundry detergent box is connected to the control panel assembly, and the control panel assembly is adapted to rotatably drive the laundry detergent box to flip out or be stored in the receiving cavity.

[0025] The mixing and dispensing structure, dispensing components, and washing machine provided in this application embodiment employ a negative pressure suction structure. By drawing the mixed liquid and air into the negative pressure chamber for mixing, the solubility rate of the laundry detergent in the mixed liquid can be improved, preventing blockage of the dispensing pipe. Furthermore, by connecting the return air port to the washing tub, when the negative pressure suction structure fails, the mixed liquid overflowing from the negative pressure chamber can be returned to the washing tub through the return air port, thus at least achieving the laundry treatment effect of the mixed liquid.

[0043] This application provides a hybrid dispensing structure applied to a washing machine, which can also be a shoe washer, washer-dryer combo, or other device for processing clothes. For examples, please refer to... Figures 1-2 , Figure 1 This is a schematic diagram of the hybrid delivery structure provided in the embodiments of this application. Figure 2 for Figure 1 The diagram shows a cross-sectional view of the hybrid delivery structure along the AA direction. The hybrid delivery structure 100 includes a mixing chamber 110 and a negative pressure suction structure 120.

[0044] The mixing chamber 110 is equipped with a mixing chamber 114 having a first liquid inlet 111, a second liquid inlet 112, and a liquid outlet 113. The first liquid inlet 111 is suitable for conveying the laundry treatment agent, and the second liquid inlet 112 is suitable for water intake, so that the laundry treatment agent and water are mixed in the mixing chamber 114. The negative pressure suction structure 120 is equipped with a negative pressure chamber 124 having a suction port 121, a return air port 122, and a dispensing port 123. The suction port 121 is connected to the liquid outlet 113, and the return air port 122 and the dispensing port 123 are both used to connect to the washing tub of the washing machine. The negative pressure chamber 124 draws the mixed liquid through the suction port 121 and dispenses the mixed liquid into the washing tub of the washing machine through the dispensing port 123. The return air port 122 is used to draw air from the washing tub of the washing machine so that the mixed liquid is mixed with air before being dispensed into the washing tub of the washing machine, or to dispense the mixed liquid overflowing from the negative pressure chamber 124 into the washing tub of the washing machine.

[0045] In practical applications, the laundry detergent flows into the mixing chamber 114 through the first inlet 111 and mixes with the water in the mixing chamber 114 to form a liquid mixture. When the negative pressure suction structure 120 is functioning normally, the liquid mixture is drawn into the negative pressure chamber 124 through the suction port 121, while air is drawn into the negative pressure chamber 124 through the air return port 122 to mix with the liquid mixture, forming a gas-liquid mixture. This gas-liquid mixture is then added to the washing tub through the discharge port 123 to treat the clothes. When the negative pressure suction structure 120 fails, the negative pressure chamber 124 loses its negative pressure suction function. As a result, after the liquid mixture enters the negative pressure chamber 124 through the suction port 121, part of it will be added to the washing tub through the discharge port 123, while the overflowing part will flow into the washing tub through the air return port 122.

[0046] Understandably, when external air mixes with the liquid mixture, numerous tiny bubbles are formed. These bubbles increase the contact area between the laundry detergent and water in the mixture, thereby promoting the dissolution of the detergent. Furthermore, the formation of bubbles also helps the detergent molecules to distribute evenly in the water, further improving the solubility rate. Moreover, the gas-liquid mixture formed by the mixture of liquid and air flows out of the negative pressure suction structure 120 with considerable force, preventing pipe blockage during rapid flow. In some embodiments, the gas-liquid mixture can also clean the washing machine door seal and door glass as it flows into the washing tub.

[0047] The mixing and dispensing structure 100 provided in this embodiment employs a negative pressure suction structure 120. By drawing the mixed liquid and air into the negative pressure chamber 124 for mixing, the solubility rate of the laundry detergent in the mixed liquid can be improved, and blockage of the dispensing pipe can be avoided. Furthermore, by connecting the return air port 122 to the washing tub, when the negative pressure suction structure 120 fails, the mixed liquid overflowing from the negative pressure chamber 124 can be returned to the washing tub through the return air port 122, thus at least achieving the laundry detergent treatment effect of the mixed liquid. This prevents the mixed liquid from overflowing onto the electrical components of the washing machine or onto the outside, avoiding safety hazards or property damage to the user.

[0048] Optionally, the mixing chamber 114 is also provided with an agitator, which is adapted to agitate to improve the mixing efficiency of the laundry detergent and water.

[0049] In some embodiments, the negative pressure suction structure 120 includes a Venturi tube 125 and a return air pipe 126. The Venturi tube 125 includes an inlet end forming the suction port 121, an outlet end forming the dispensing port 123, and a throat forming the negative pressure chamber 124, the throat having an opening; one end of the return air pipe 126 is connected to the opening, and the other end forms the return air port 122. Thus, by using the Venturi tube 125 and the return air pipe 126 to form the negative pressure suction structure 120, the structure is simple and the effect is good.

[0050] In some embodiments, the mixing and dispensing structure 100 further includes a one-way valve body 130, which is disposed at the first inlet 111 to restrict the one-way flow of the clothing treatment agent in the first inlet 111. This prevents backflow of the mixture in the mixing chamber 114, thus preventing abnormal dispensing. Optionally, a one-way valve body 130 is also disposed in the second inlet 112.

[0051] In some embodiments, the number of first liquid inlets 111 is at least two, and each first liquid inlet 111 is used to deliver a laundry treatment agent with a corresponding function. For example, there are two first liquid inlets 111, one of which is used to deliver a laundry treatment agent with a laundry washing function, and the other is used to deliver a laundry treatment agent with a laundry softening function. In this way, the mixing chamber 114 can simultaneously mix laundry treatment agents with multiple functions, improving the mixing and dispensing efficiency of the mixing and dispensing mechanism.

[0052] The mixing and dispensing structure 100 provided in this embodiment employs a negative pressure suction structure 120. By drawing the mixed liquid and air into the negative pressure chamber 124 for mixing, the solubility rate of the laundry detergent in the mixed liquid can be improved, and blockage of the dispensing pipe can be avoided. Furthermore, by connecting the return air port 122 to the washing tub, when the negative pressure suction structure 120 fails, the mixed liquid overflowing from the negative pressure chamber 124 can be returned to the washing tub through the return air port 122, thus at least achieving the laundry detergent treatment effect of the mixed liquid. This prevents the mixed liquid from overflowing onto the electrical components of the washing machine or onto the outside, avoiding safety hazards or property damage to the user.

[0053] This application also provides a delivery component, for example, please refer to [link to example]. Figures 3-4 , Figure 3 This is a schematic diagram of the connection between the dispensing component and the washing tub provided in an embodiment of this application. Figure 4 This is a schematic diagram of the connection between the dispensing pump and the mixing chamber provided in an embodiment of this application. The detergent dispensing assembly is applied to a washing machine and includes a laundry detergent dispenser 200, a dispensing pump 300, and the mixing dispensing structure 100 in any of the above embodiments. The laundry detergent dispenser 200 is suitable for holding laundry detergent; the dispensing pump 300 is connected to the laundry detergent dispenser 200 and the first liquid inlet 111, and is used to pump the laundry detergent to the liquid inlet.

[0054] In practical applications, in response to the water inlet command for the washing machine, the washing machine control pump 300 and the washing machine inlet pump start working to pump the laundry detergent and water in the laundry detergent box 200 into the mixing chamber 114 respectively, so that the laundry detergent and water are mixed in the mixing chamber 114.

[0055] In some embodiments, the laundry detergent dispenser 200 has a first chamber 210 and a second chamber 220 spaced apart. The first chamber 210 is used to hold a first treatment agent, and the second chamber 220 is used to hold a second treatment agent. There are at least two first inlets 111. The dispensing pump 300 has a first pumping channel 310 and a second pumping channel 320. The first pumping channel 310 connects the first chamber 210 and one first inlet 111, and the second pumping channel 320 connects the second chamber 220 and another first inlet 111. For example, the first treatment agent is detergent, and the second treatment agent is fabric softener. The first pumping channel 310 and the second pumping channel 320 are not interconnected and are used to pump detergent and fabric softener, respectively.

[0056] Preferably, the dispensing pump 300 is a peristaltic pump. The first pumping channel 310 is connected to the first chamber 210 and the first liquid inlet 111, the second pumping channel 320 is connected to the second chamber 220 and the first liquid inlet 111, and the washing tub is connected to the dispensing port 123 and the air return port 122 via flexible hoses.

[0057] Preferably, the laundry detergent dispenser 200 is made of a transparent material. For example, the laundry detergent dispenser 200 is made of transparent plastic or tempered glass. This allows the user to easily observe the remaining amount of laundry detergent in the first chamber 210 and the second chamber 220, and thus replenish the laundry detergent in a timely manner.

[0058] The dispensing component 10 and the mixing dispensing structure 100 provided in this application embodiment use a negative pressure suction structure 120 to draw the mixed liquid and air into the negative pressure chamber 124 for mixing. This improves the solubility of the laundry detergent in the mixed liquid and prevents blockage of the dispensing pipe. Furthermore, by connecting the return air port 122 to the washing tub, when the negative pressure suction structure 120 fails, the mixed liquid overflowing from the negative pressure chamber 124 can be returned to the washing tub through the return air port 122, thus at least achieving the laundry detergent treatment effect of the mixed liquid. This prevents the mixed liquid from overflowing onto the electrical components of the washing machine or onto the outside, avoiding safety hazards or property damage to the user.

[0059] This application also provides a washing machine, for example, please refer to [link to example]. Figures 5-6 , Figure 5 This is a schematic diagram of the washing machine in its first state according to an embodiment of this application. Figure 6 This is a schematic diagram of the washing machine in a second state according to an embodiment of this application. The washing machine 1 includes the dispensing component 10 in any of the above embodiments. The washing machine 1 also includes a cabinet 20 and a control panel component 30.

[0060] The front of the housing 20 forms an open receiving cavity. A control panel assembly 30 is rotatably connected to the opening of the housing 20. The laundry detergent dispenser 200 is connected to the control panel assembly 30, and the control panel assembly 30 is adapted to rotatably drive the laundry detergent dispenser 200 to flip out or retract into the receiving cavity. Thus, by rotating the control panel assembly 30 to flip the laundry detergent dispenser 200 to the front of the housing 20 or retract it into the receiving cavity, the laundry detergent dispenser 200 will not interfere with surrounding objects during use, allowing the washing machine 1 to meet the user's need for a built-in installation.

[0061] For example, the control panel assembly 30 includes a mounting plate 31 and an operation panel 32. The mounting plate 31 is rotatably connected to the opening of the housing 20, and has a first position with the opening open and a second position with the opening closed. The operation panel 32 is fixedly connected to the mounting plate 31. When the mounting plate 31 is in the first position, the first operation panel 32 is positioned facing upwards towards the washing machine. When the mounting plate 31 is in the second position, the first operation panel 32 is retracted into the receiving cavity. Thus, the user can easily view the operation panel 32 by flipping it upwards without bending or squatting, avoiding any impact on the user experience. Furthermore, by flipping the mounting plate 31 to the second position, the operation panel 32 can be retracted into the receiving cavity and the opening closed, giving the washing machine 1 a simple and elegant appearance. Additionally, since the control panel assembly 30 is located on the front side of the housing 20, the operation panel 32 will not interfere with surrounding objects during use, allowing the washing machine 1 to meet the user's embedded needs and conforming to the trend of modern interior design.

[0062] Optionally, the laundry detergent dispenser 200 is fixedly connected to the mounting plate 31. When the mounting plate 31 is in the first position, the laundry detergent dispenser 200 is flipped out to the front of the housing 20, and the first chamber 210 and the second chamber 220 open upwards towards the washing machine. When the mounting plate 31 is in the second position, the laundry detergent dispenser 200 is stored in the receiving cavity. Preferably, the laundry detergent dispenser 200 and the mounting plate 31 are integrally formed.

[0063] The washing machine 1 provided in this embodiment uses a mixing and dispensing structure 100 to draw the mixed liquid and air into a negative pressure chamber 124 via a negative pressure suction structure 120 for mixing. This improves the solubility of the laundry detergent in the mixed liquid and prevents blockage of the dispensing pipe. Furthermore, by connecting the return air port 122 to the washing tub, when the negative pressure suction structure 120 fails, the mixed liquid overflowing from the negative pressure chamber 124 can be returned to the washing tub through the return air port 122, thus achieving at least the laundry detergent function of the mixed liquid. This prevents the mixed liquid from overflowing onto the electrical components or external parts of the washing machine 1, avoiding safety hazards or property damage to the user.

Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the above embodiments are only for the purpose of helping to understand the methods and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
