Description

Technical Field

[0001] The present invention belongs to the field of household washing electrical appliances, and specifically relates to a washing additive input device. In particular, it relates to an interlocking switching valve of the washing additive input device, and further relates to a control method of the aforementioned washing additive input device.

Background Art

[0002] As people's living standards continue to improve, washing machines have become an essential household appliance in family life. In conventional drum washing machines and fully automatic vortex washing machines, a washing additive input device is usually installed for adding detergent into the washing tub of the washing machine. Generally, by the action of the water intake flow of the washing machine, the washing additive in the washing additive input device, which is manually or automatically sucked up by the user, is poured into the washing tub of the washing machine, thereby achieving the purpose of adding and using the washing additive. The aforementioned washing additive may be any one or combination of conventional additives that can enhance the clothing treatment effect, for example, detergents, fabric softeners, disinfectants, etc.

[0003] Conventional input devices are generally suction pumps additionally installed on each input water path. By utilizing the suction acting force of the pump, the washing additive in the corresponding input water path is drawn in, thereby achieving the effect of putting the sucked-up washing additive into the washing machine tub together with the water intake flow. However, the cost of the aforementioned suction pump is high. In order to reduce the cost, a detergent input device that sucks up the washing additive using a negative pressure suction structure has been proposed. However, for the aforementioned negative pressure suction structure, it is necessary to further separately provide one water intake path for providing negative pressure, and the water path has become complicated.

[0004] In particular, when using negative pressure to draw up laundry additives from the reservoir, the outlet of the water channel used to draw up the laundry additives is in communication with the atmosphere, resulting in insufficient suction force within the channel and a slow rate at which the laundry additives are drawn up from the reservoir. Therefore, a problem that urgently needs to be solved is how to automatically control and close the outlet of the water channel used to draw up the laundry additives in order to improve the rate at which they are drawn up.

[0005] In view of the above, the present invention is proposed. [Overview of the project]

[0006] The technical problem that this invention aims to solve is to provide a laundry additive dispensing device that overcomes the shortcomings of the prior art and achieves the objective of simultaneously integrating the water channels for dispensing different types of laundry additives and providing a negative pressure suction force for the laundry additives to the other water channels. Furthermore, this invention makes it possible to use tap water or secondary supply water drawn from an external source as the water for dispensing the laundry additives, thereby providing a laundry additive dispensing device that enhances the water intake mode and achieves the objective of automatically reusing the secondary supply water.

[0007] To solve the aforementioned technical problems, the basic concepts of the technical ideas adopted by this invention are as follows.

[0008] The laundry additive dispenser comprises a first dispenser channel used to draw up a first laundry additive stored in a first liquid storage chamber, and a second dispenser channel used to draw up a second laundry additive stored in a second liquid storage chamber. Negative pressure suction structures are provided on both the first and second dispenser channels, and the negative pressure ports of the two negative pressure suction structures are in communication with each other. When an intake water flow enters one dispenser channel, it creates negative pressure in the other dispenser channel, drawing up the corresponding laundry additive.

[0009] Furthermore, the aforementioned negative pressure suction structure consists of venturi tubes connected in series on the water inlet channel. The venturi tubes are equipped with negative pressure ports that utilize the incoming water flow to create negative pressure. The negative pressure ports of the venturi tubes located on the two water inlet channels are in communication with each other.

[0010] Furthermore, the inlets of the two intake channels are each connected to corresponding intake valves that control the opening and closing of the intake water flow.

[0011] The outlets of both input channels are connected to the reservoirs of the input device.

[0012] The central sections of the two input channels are connected to each other in a one-to-one correspondence with storage chambers for storing the corresponding type of laundry additive.

[0013] Preferably, a check valve is provided at the point where the liquid storage chamber and the inlet channel communicate with each other, allowing fluid communication in only one direction, and is used to control the flow of the liquid so that it flows only from the liquid storage chamber towards the inlet channel.

[0014] Furthermore, the dispensing device is equipped with a water case.

[0015] The water case is equipped with a water tank, which has a groove-like shape with an open front and an open top.

[0016] An upper cover is fitted over the opening at the top of the water storage tank. A water channel is integrally provided inside the upper cover, and the water channel includes at least an inlet channel.

[0017] At least the lower portion of the water tank constitutes a water outlet for dispensing the laundry additive mixture into the washing machine tub, the upper portion constitutes a mounting space for the detergent case to be assembled in a pull-out manner, and the liquid storage chamber is installed inside the detergent case.

[0018] Furthermore, the water tank is equipped with a removable dispenser case. Inside the dispenser case is a compartment for manually adding different types of laundry additives.

[0019] An injection chamber is provided on the upper cover, located above the input chamber. An injection port is provided on the bottom wall of the injection chamber, opening towards the input chamber, and the outlet end of the input water channel communicates with the injection chamber.

[0020] Furthermore, the outlet ends of the two inlet channels are connected to the first injection chamber.

[0021] The second injection chamber is in communication with the third inlet channel, and the intake end of the third inlet channel is connected to another intake valve, which is used to controllably supply the intake water flow into the third inlet channel.

[0022] Preferably, the first input chamber below the first spray chamber is for manually adding detergent, and the second input chamber below the second spray chamber is for manually adding fabric softener.

[0023] Furthermore, a suction pump is provided on the input device. The suction pump is in communication with the main intake channel, and a secondary supply water inlet is provided on the suction pump, which is in fluid communication with an externally connected secondary supply water source and is used to supply secondary supply water to the main intake channel.

[0024] The intake end of the main intake channel is connected to the intake end of the first inlet channel and the intake end of the second inlet channel, respectively, and the outlet end is connected to the first injection chamber.

[0025] Preferably, check valves are provided at the interconnections between the first inlet channel and the main intake channel, and between the second inlet channel and the main intake channel, to control the water flow so that it flows along the inlet channel towards the main intake channel. The interconnections between the inlet channel and the main intake channel are located upstream of the negative pressure suction structure. The outlet ends of both the first and second inlet channels are interconnected with the main intake channel.

[0026] More preferably, the water absorption pump is provided with an inlet and an outlet that communicate with the pump chamber. The inlet communicates with the main water intake channel, and the outlet communicates with the first injection chamber.

[0027] The present invention further provides a control method for a washing machine to which the washing additive input device described in any of the above is attached. The control method includes the following.

[0028] When injecting the first washing additive / the second washing additive,

[0029] First, water is taken in the second input channel / the first input channel, and negative pressure is generated using the flowing water intake flow, and the first washing additive stored in the first liquid storage chamber / the second washing additive stored in the second liquid storage chamber is drawn into the first input channel / the second input channel.

[0030] Then, water is taken in the first input channel and the second input channel at the same time, and the first washing additive / the second washing additive sucked into the first input channel / the second input channel using the flowing water is poured into the water storage tank and input into the washing machine tub.

[0031] Furthermore, when the washing machine takes water using secondary water supply,

[0032] First, the water intake valve is opened, the water absorption pump is stopped, and the first washing additive stored in the first liquid storage chamber / the second washing additive stored in the second liquid storage chamber is input until the pump chamber of the water absorption pump is filled with tap water.

[0033] Next, the water intake valve is closed, the water absorption pump is started, and the water absorption pump draws secondary water supply into the pump chamber through the secondary water supply inlet, and then flows into the water storage tank through the input channel and the main water intake channel.

[0034] Furthermore, when the first laundry additive, which has been manually added to the input chamber, is introduced, water is simultaneously drawn into the first and second input channels. The intake water flows through the first injection chamber into the first input chamber, injecting the first laundry additive, which has been manually added to the first input chamber, into the reservoir and then into the washing machine tub. When the second laundry additive, which has been manually added to the input chamber, is introduced, water is drawn into the third input channel. The intake water flows through the second injection chamber into the second input chamber, injecting the second laundry additive, which has been manually added to the second input chamber, into the reservoir and then into the washing machine tub.

[0035] By adopting the aforementioned technical concept, the present invention has the following beneficial effects compared to the prior art.

[0036] 1. The present invention enables the use of negative pressure ports of negative pressure suction structures located on different input channels to communicate with each other. By applying the negative pressure generated by the water flow in a selected input channel to another input channel, laundry additives stored in a liquid storage chamber connected to that input channel can be drawn up. Subsequently, water is simultaneously drawn into two more input channels, and the incoming water flows simultaneously into the first and second input channels. This mixes the laundry additives drawn up in the previous step with the incoming water to form a laundry additive mixture, which can then be introduced to the outside. This achieves a remarkable technological advancement by integrating the dual functions of the input channel—a negative pressure generating channel for drawing up laundry additives and a function for mixing the drawn-up laundry additives with the incoming water and introducing them—into the input channel.

[0037] 2. In this invention, by directly connecting the suction pump in parallel to the input water channel of the dispensing device, the dispensing device can use the suction water flow drawn in by the suction pump as the intake water flow, thereby washing away the laundry additive to be dispensed within the dispensing device. This achieves the effect of automatically dispensing the laundry additive by directly using the secondary supply water drawn in by the washing machine. Furthermore, by connecting the suction pump in parallel to the input water channel of the washing machine, the dispensing channel can be effectively utilized to fill the pump chamber of the suction pump with tap water supplied when the laundry additive is dispensed. This achieves a remarkable technological advancement in that the suction pump is automatically controlled to meet the operating requirements.

[0038] Furthermore, the present invention has a simple structure, a straightforward method, remarkable effects, and is suitable for widespread use.

[0039] The technical problem that this invention aims to solve is to overcome the shortcomings of the prior art and to provide an interlocking switching valve that achieves the objective of automatically switching the outlet for different water channels. Furthermore, this invention provides an interlocking switching valve that achieves the objective of performing interlocking opening and closing control for two water channels by utilizing the intake water flow of different water channels. Moreover, this invention provides a laundry additive dispensing device and control method that achieves the objective of performing interlocking opening and closing control for the outlet of one water channel by utilizing the intake water flow of one water channel. This achieves the effect of automatically and efficiently drawing up and dispensing different types of laundry additives.

[0040] To solve the aforementioned technical problems, the basic concepts of the technical ideas adopted by this invention are as follows.

[0041] The interlocking switching valve has two passages for different intake water flows, with the first and second passages communicating with each other. Each of the two passages is equipped with a valve plug that can move in the inlet or outlet direction in response to the impact of the water flow. When the first / second passage takes in water, the intake water flow moves the valve plugs in the first / second passages toward the outlet direction, closing the outlets of the first / second passages, and moves the valve plugs in the second / first passages toward the inlet direction, closing the inlets of the second / first passages. The intake water flows out from the outlets of the second / first passages.

[0042] Furthermore, a third outflow passage is also provided. The inlet of the third outflow passage is connected to the communication point of the two passages. When the first and second passages take in water simultaneously, the intake water flow moves the valve plugs in both the first and second passages toward the outlet, closing the outlets of the first and second passages. The intake water flow flows out from the outlet of the third outflow passage.

[0043] Furthermore, the switching valve is provided with a first passage and a second passage that are parallel to each other. The ends of the two passages are the inlet and outlet, respectively, and the central parts of the two passages communicate with each other in a one-to-one correspondence with the ends of the connecting passage. The central part of the connecting passage communicates with the inlet of the third outlet passage, and the outlet of the third connecting passage is located on the same side of the switching valve as the outlets of the first passage and the second passage.

[0044] Furthermore, within the two passages of the switching valve, there are valve plugs that can move freely along the passages, and within each of the two passages, there are elastic components. Both ends of the elastic components are connected to the housing of the switching valve and to the corresponding valve plugs in the passages, respectively, and are used to maintain the position where the valve plugs are normally connected to the connecting passage and the corresponding passage. Preferably, when the valve plugs are in the normal position, the outlet of the passage where the valve plugs are located is in fluid communication with the connecting passage. More preferably, when the valve plugs are in the normal position, the inlet of the passage where the valve plugs are located is blocked from the connecting passage.

[0045] Furthermore, the axial height of the valve plug is smaller than the distance between the mutual communication point between the passage where the valve plug is located and the connecting passage and the passage inlet, and the axial height of the valve plug is smaller than the distance between the mutual communication point between the passage where the valve plug is located and the connecting passage and the passage outlet. When the valve plug is positioned to close the passage inlet, the outlet of the passage where the valve plug is located is in fluid communication with the connecting passage. When the valve plug is positioned to close the passage outlet, the inlet of the passage where the valve plug is located is in fluid communication with the connecting passage.

[0046] Furthermore, slide rails are provided within each of the two passages, installed in the direction of extension of the passage. A sliding part is provided on the outer wall of the valve plug, which is inserted in accordance with the first slide rail, and is used to restrict the movement of the valve plug to only the direction of extension of the passage.

[0047] Furthermore, the inlets of the two passages are in close, separable contact with at least a portion of one end face facing the inlet of the valve plug, and at least one inlet seal ring is provided around the aforementioned position of close, separable contact with each other. The aforementioned inlet seal ring is provided on the inner wall of the passage inlet or on the end face facing the inlet of the valve plug. The outlets of the two passages are in close, separable contact with at least a portion of the end face facing the outlet of the valve plug, and at least one outlet seal ring is provided around the aforementioned position of close, separable contact with each other, and the aforementioned outlet seal ring is provided on the inner wall of the passage outlet or on the end face facing the outlet of the valve plug.

[0048] Preferably, one end of the valve plug facing the passage inlet is hemispherical. An inlet seal ring is provided around the inner wall of the passage inlet, and the radial dimension of the inlet seal ring is smaller than the maximum radial dimension of the hemisphere. The other end of the valve plug facing the passage outlet is flat, and an outlet seal ring is provided coaxially on the flat surface of the valve plug. An annular convex rib is provided around the passage outlet, projecting inward in the radial direction, and the radial dimension of the outlet seal ring is larger than the radial dimension of the inner circumference of the annular convex rib.

[0049] The present invention further provides a dispensing device. The dispensing device comprises a first dispensing channel used to draw up a first laundry additive stored in a first liquid storage chamber, a second dispensing channel used to draw up a second laundry additive stored in a second liquid storage chamber, and a main intake channel for dispensing the laundry additive mixture and / or intake water to the outside, and has the aforementioned interlocking switching valve. The outlets of the first dispensing channel and the outlets of the second dispensing channel communicate with each other in a one-to-one correspondence with the inlets of the first and second passages of the interlocking switching valve, and the outlets of the two passages of the interlocking switching valve communicate with each other with the main intake channel.

[0050] Furthermore, negative pressure suction structures are provided in both the first and second input channels. The negative pressure ports of the two negative pressure suction structures are in communication with each other, and when the intake water flows into one input channel, it creates negative pressure in the other input channel, drawing up the corresponding laundry additive.

[0051] Furthermore, the outlet of the third outflow passage of the interlocking switching valve is connected to the main intake water channel.

[0052] The present invention further provides a control method for the dispensing device described in any of the above. The control method includes the following: When dispensing the first laundry additive drawn up into the first dispensing channel / the second laundry additive drawn up into the second dispensing channel, water is drawn into the first dispensing channel / the second dispensing channel. The intake water flow enters the first passage / second passage of the interlocking switching valve, and the valve plugs in the first passage / second passage correspondingly close the outlets of the first passage / second passage, and the valve plugs in the second passage / first passage correspondingly close the inlets of the second passage / first passage. The laundry additive, together with the intake water flow, flows into the main intake channel from the outlet of the second passage / first passage and is dispensed to the outside.

[0053] Furthermore, when adding the first laundry additive / second laundry additive,

[0054] First, water is drawn into the second input channel / first input channel. The intake water flow closes the outlets of the second passage / first passage and the inlet of the first passage / second passage of the interlocking switching valve, thereby closing the outlets of the first input channel / second input channel. Negative pressure is generated using the incoming intake water flow, drawing the first laundry additive stored in the first storage chamber / second laundry additive stored in the second storage chamber into the first input channel / second input channel.

[0055] Next, water is simultaneously drawn into the first and second input channels. The intake water flow closes the outlets of both the first and second passages of the interlocking switching valve, while opening the outlet of the third outflow passage. Using the incoming water flow, the first and second laundry additives, which have been drawn up into the first and second input channels, are then discharged into the main intake channel and released to the outside.

[0056] By adopting the aforementioned technical concept, the present invention has the following beneficial effects compared to the prior art.

[0057] 1. The present invention achieves the objective of synchronously closing the inlet of one passage when water is supplied to a different passage, by configuring the interlocking switching valve as described above. This achieves the effect of performing interlocking opening and closing control for two different passages using different water intake flows.

[0058] 2. The present invention achieves the effect that when an input channel draws up laundry additives, the outlet of the corresponding channel is automatically closed by having different input channels fluidly communicate with each other via interlocking switching valves. This creates a sealed space in the input channel that draws up laundry additives, achieving a remarkable technological advancement by significantly improving the suction speed of the laundry additives drawn up from the storage chamber.

[0059] Furthermore, the present invention has a simple structure, a straightforward method, remarkable effects, and is suitable for widespread use.

[0060] The technical problem that this invention aims to solve is to overcome the shortcomings of the prior art and to provide a laundry additive dispensing device that can use tap water or secondary water drawn from an external source as the water for dispensing laundry additives, thereby enhancing the water intake mode and enabling the automatic reuse of secondary water. Furthermore, this invention provides a laundry additive dispensing device with an integrated water intake pump that uses a water source drawn from an external source to dispense laundry additives into the washing drum of a washing machine.

[0061] To solve the aforementioned technical problems, the basic concepts of the technical ideas adopted by this invention are as follows.

[0062] A laundry additive dispensing device with an integrated water intake pump comprises a water case equipped with a water storage tank for drawing water into the washing machine tub; a liquid storage chamber installed inside the water case for storing laundry treatment agents; an automatic dispensing module that connects the liquid storage chamber and the water storage tank of the water case to each other, drawing the laundry treatment agents in the liquid storage chamber into the water storage tank and dispensing them to the outside together with the intake water flowing into the water storage tank; an intake pipe whose outlet is connected to the automatic dispensing module and which is equipped with an intake valve at the intake, for supplying tap water to the automatic dispensing module in a controllable open / closed state; and a water intake pump that is connected in series on the intake pipe and is further equipped with a secondary supply water inlet that is in fluid communication with an externally connected secondary supply water source, and is used to introduce an intake water flow consisting of tap water supplied from the intake valve or secondary supply water supplied from the water intake pump into the automatic dispensing module.

A first hose is connected to the outlet of the intake valve, and a second hose and a third hose are connected to the inlet and outlet of the suction pump, respectively. The end of the first hose is connected to the end of the second hose via a connecting fitting to establish fluid communication, and the end of the third hose is connected to the intake channel provided inside the water case via an intake fitting installed on the water case to establish fluid communication.

[0065] Furthermore, check valves are provided at the inlet of the suction pump and / or the second hose and / or the connecting fitting and / or the first hose and / or the outlet of the intake valve, and these check valves are used to control the flow of water along the intake valve in only one direction toward the suction pump.

[0066] Furthermore, the water case includes a water tank with a groove-like shape that is open at the front and open at the top. An upper cover is fitted to cover the open top of the water tank. A water channel is integrally provided inside the upper cover, and the water channel includes at least an intake channel. An intake joint is provided on the upper side of the upper cover, which protrudes upward and into which the end of the third hose is inserted and connected, and the intake joint connects the intake channel and the suction pump. At least the lower part of the water tank constitutes a water outlet for introducing the laundry additive mixture into the washing machine tub, and the upper part constitutes a mounting space for the detergent case to be assembled in a pull-out manner, and the liquid storage chamber is installed inside the detergent case.

[0067] Furthermore, the automatic dispensing module is equipped with a pump, the pump inlet is connected to the storage chamber via a fluid guide structure, and the pump outlet is connected to the water intake channel.

[0069] Furthermore, the intake valve has one inlet and multiple outlets, and the valve core of the intake valve is used to control the inlet and each outlet to communicate with each other alternately.

Next, the intake valve is closed and the suction pump is started. The suction pump draws secondary water supply into the pump chamber through the secondary water supply inlet, and then allows it to flow into the storage tank through the intake pipe and suction channel.

[0074] Furthermore, when the washing machine uses secondary water supply to draw water, it first opens the intake valve and stops the suction pump, which continues for a set time t1, and then closes the intake valve and starts the suction pump.

[0092] To achieve the aforementioned objectives, we propose the following configuration.

[0093] The control method for the laundry additive dispensing device described in any of the above includes the following:

[0094] The laundry additive dispenser acquires the pre-set amount to be dispensed and the amount of laundry additive in the manual dispenser module.

[0095] Formula: Differential input amount = Pre-set input amount - The differential input amount is obtained according to the amount of additive in the manual input module.

[0096] The automatic dispensing module is activated, drawing the difference in the amount of laundry additive from the storage chamber into the manual dispensing module.

[0097] Water is drawn into the water case, mixed with the laundry additive in the manual dispensing module, and then dispensed externally.

[0098] Furthermore, it determines whether the amount of laundry additive in the manual dispensing module is greater than the preset dispensing amount.

[0099] If the amount is large, the automatic dispensing module will stop operating, draw water directly into the water case, mix it with the laundry additive in the manual dispensing module, and dispense it externally.

[0100] If the amount is small, the automatic dispensing module will start operating, and the difference in the amount of laundry additive will flow into the manual dispensing module, and then the laundry additive in the manual dispensing module will be dispensed externally by drawing water into the water case.

[0101] Furthermore, it also includes the following:

[0102] The laundry additive dispenser determines the type of laundry additive to be added.

[0103] The amount of laundry additive in the dispenser corresponding to the determined type of laundry additive is detected.

[0104] Formula: Differential input amount = Pre-set input amount - The differential input amount is obtained according to the amount of additive in the manual input module.

[0105] The system controls and operates pumps that are connected to the storage chambers corresponding to the determined type of laundry additive. The determined type of laundry additive in the corresponding storage chamber is then sucked and transported via the pumps to the corresponding intake channel until the amount of laundry additive sucked up reaches the differential input amount.

[0106] Subsequently, water is drawn into the corresponding intake channel, and the intake water flow and laundry additive are introduced into the corresponding input chamber and mixed to form a laundry additive mixture, which is then poured into the washing drum of the washing machine through the outlet of the water case.

[0107] By adopting the aforementioned technical concept, the present invention has the following beneficial effects compared to the prior art.

[0108] With the aforementioned configuration, the present invention integrates both automatic and manual dispensing functions for laundry additives into the washing machine's dispensing device, thereby diversifying the dispensing methods. Furthermore, the manual dispensing module can be used to dispense the additives dispensed by the automatic dispensing module to an external outlet. This allows the dispensing device to apply two dispensing modes with only a single dispensing outlet, significantly simplifying the structural complexity.

[0109] Furthermore, the present invention has a simple structure, a straightforward method, remarkable effects, and is suitable for widespread use.

It should be noted that these drawings and textual descriptions are not intended to limit the scope of the concept of the present invention in any way, but rather to explain the concept of the present invention to those skilled in the art by referring to specific embodiments. [Modes for carrying out the invention]

[0113] To further clarify the purpose, technical concept, and advantages of the embodiments of the present invention, the technical concept of the embodiments will be clearly and completely described below with reference to the drawings of the embodiments. The following embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0114] In describing this invention, unless otherwise explicitly defined or limited, the terms "attach," "connect," and "connect" should be understood in a broad sense. For example, a connection may be fixed, detachable, or integral. Furthermore, a connection may be mechanical or electrical. Also, a connection may be direct or indirect, mediated through an intermediate intermediary. Those skilled in the art will be able to understand the specific meaning of these terms in this invention depending on the specific circumstances. [Examples]

[0115] As shown in Figures 10 and 11, an embodiment of the present invention introduces an interlocking switching valve 8. The interlocking switching valve 8 has two passages, a first passage 81 and a second passage 82, for allowing different intake water flows into it. The first passage 81 and the second passage 82 are in communication with each other. Valve plugs 85 are provided in the two passages, which are movable in the inlet or outlet direction in response to the impact of the water flowing through the passages.

[0116] When water is drawn in from the first inlet 811 of the first passage 81, the intake water flow moves the first valve plug 851 in the first passage 81 toward the first outlet 812, closing the first outlet 812 of the first passage 81, and moves the second valve plug 852 in the second passage 82 toward the second inlet 821, closing the second inlet 821 of the second passage 82. The intake water flow then flows out from the second outlet 822 of the second passage 82.

[0117] When water is drawn in from the second inlet 821 of the second passage 82, the intake water flow moves the second valve plug 852 in the second passage 82 toward the second outlet 822, closing the second outlet 822 of the second passage 82, and moves the first valve plug 851 in the first passage 81 toward the first inlet 811, closing the first inlet 811 of the first passage 81. The intake water flow then flows out from the first outlet 812 of the first passage 81.

[0118] With the interlocking switching valve configured as described above, the objective is achieved that when water is supplied to one passage, the inlet of the other passage is closed synchronously. This achieves the effect of controlling the opening and closing of two different passages in conjunction with each other by utilizing different water intake flows.

[0119] In an embodiment of the present invention, the aforementioned interlocking switching valve 8 further comprises a third outlet passage 83. The inlet of the third outlet passage 83 is connected to the communication position between the first passage 81 and the second passage 82. When the first passage 81 and the second passage 82 take in water simultaneously, the intake water flow moves the first valve plug 851 in the first passage 81 toward the first outlet 812 and the second valve plug 852 in the second passage 82 toward the second outlet 822, thereby closing the first outlet 812 of the first passage 81 and the second outlet 822 of the second passage 82. The intake water flow flows out from the third outlet 831 of the third outlet passage 83.

[0120] The aforementioned configuration achieves the objective of switching the water outlet when supplying water to different passages simultaneously, thereby achieving the effect of switching and adjusting the valve body's operating mode in accordance with any or a combination of water supply methods.

[0121] In an embodiment of the present invention, the interlocking switching valve 8 comprises a columnar housing 80. A first passage 81 and a second passage 82 are provided within the columnar housing 80, extending in the axial direction and parallel to each other. A third outlet passage 83 is provided between the first passage 81 and the second passage 82, extending parallel to each other. The first inlet 811 of the first passage 81 and the second inlet 821 of the second passage 82 are located on the same side of the columnar housing 80, while the first outlet 812 of the first passage 81, the second outlet 822 of the second passage 82, and the third outlet 831 of the third outlet passage 83 are all located on the other side of the columnar housing 80. The central portions of the first passage 81 and the second passage 82 each communicate with each other in a one-to-one correspondence with both ends of a connecting passage 84, and the central portion of the connecting passage 84 communicates with each other with the inlet of the third outlet passage 83. Preferably, the extension directions of the communication passage 84 are perpendicular to each other with respect to the axial orientation of the columnar housing 80.

[0122] In an embodiment of the present invention, valve plugs 85 that can move freely along the passages are provided in the first passage 81 and the second passage 82 of the interlocking switching valve 8 described above. In order to reduce the occurrence of situations in which the valve plugs 85 become inoperable, the following configuration may be used. That is, elastic components are provided in each of the two passages, and both ends of the elastic components are connected to the housing 80 of the interlocking switching valve 8 and to the corresponding valve plugs 85 in the passages, respectively, and are used to maintain the valve plugs 85 in a position where they connect to the communication passage 84 and the corresponding passage under normal conditions. The aforementioned elastic components may be elastic structures of any type in the prior art. For example, the elastic component is a spring, which extends axially along the passage, with one end of the spring connected to the valve plug 85 and the other end connected to the inner wall of the passage, thereby using the elasticity provided by the spring to maintain the valve plug 85 in the normal position. Preferably, when the valve plug 85 is in the normal position, the outlet of the passage where the valve plug 85 is located is in fluid communication with the communication passage 84. As a result, the water flow entering the passage via the communication passage 84 can directly drive the valve plug 85 and move it toward the inlet, thus avoiding a situation in which the valve plug 85 becomes inoperable. More preferably, in order to further avoid a situation in which the valve plug 85 becomes inoperable and water flow introduced into another passage cannot be smoothly discharged, the following configuration may be used. That is, when the valve plug 85 is in its normal position, the inlet of the passage where the valve plug 85 is located is blocked from the communication passage 84. This ensures that the water flow flowing in from the communication passage 84 does not flow backward toward the inlet of the passage.

[0123] In an embodiment of the present invention, the axial height of the valve plug 85 is smaller than the distance between the mutual communication point between the passage where the valve plug 85 is located and the communication passage 84 and the passage inlet, and the axial height of the valve plug 85 is smaller than the distance between the mutual communication point between the passage where the valve plug 85 is located and the communication passage 84 and the passage outlet. With the above configuration, when the valve plug 85 is positioned to close the passage inlet, the outlet of the passage where the valve plug 85 is located is in fluid communication with the communication passage 84, and when the valve plug 85 is positioned to close the passage outlet, it is possible to ensure that the inlet of the passage where the valve plug 85 is located is in fluid communication with the communication passage 84. This makes it possible to achieve the objective of smoothly discharging the water flow inside the interlocking switching valve 8 to the outside.

[0124] In an embodiment of the present invention, each of the two passages is provided with a slide rail 86 installed in the direction of extension of the passage. A sliding portion is provided on the outer wall of the valve plug 85, which is inserted in correspondence with the slide rail, and is used to restrict the movement of the valve plug 85 to only the direction of extension of the passage 86. This ensures that the valve plug 85 can only slide in the axial direction of the passage and does not produce the effect of rotating around the axial direction. Preferably, the inner wall of the passage is provided with a plurality of strip-shaped convex ribs 861 that are spaced apart and project inward in the radial direction. All of the strip-shaped convex ribs 861 extend in the axial direction of the passage. The outer circumferential wall of the valve plug 85 is provided with locking grooves that are inserted one-to-one in correspondence into the strip-shaped convex ribs, thereby allowing the valve plug 85 to move only in the axial direction by the guiding action of the locking grooves and the strip-shaped convex ribs 861. More preferably, in order to prevent the valve plug 85 from coming out of the passage, a radially protruding stopper portion is provided at one end of the band-shaped convex rib 861 at the entrance of the passage. The radial height of the stopper portion is greater than the radial dimension of the locking groove and is used to restrict the valve plug 85 from coming out of the passage from the entrance.

[0125] In an embodiment of the present invention, the inlets of the two passages are in close contact with one end face of the valve plug 85 facing the inlet, at least a portion of which is separable. An inlet seal ring 855 is provided around the aforementioned position where the inlets and inlets are in close contact. The aforementioned inlet seal ring 855 is provided on the inner wall of the passage inlet or on the end face of the valve plug 85 facing the inlet. The outlets of the two passages are in close contact with the end face of the valve plug 85 facing the outlet, at least a portion of which is separable. An outlet seal ring 856 is provided around the aforementioned position where the inlets and inlets are in close contact, and the aforementioned outlet seal ring 856 is provided on the inner wall of the passage outlet or on the end face of the valve plug 85 facing the outlet. By installing seal rings at positions where the valve plug and the passage inlets and outlets correspond to each other and make contact, the effect is achieved that when the valve plug moves in accordance with the passage inlets and outlets, the passage inlets and outlets are closed accordingly.

[0126] Preferably, one end of the valve plug 85 facing the passage inlet is a hemispherical surface 853, and a circumferential inlet seal ring 855 is provided on the inner circumferential wall at the passage inlet position, projecting in the radial direction of the passage. The radial dimension of the inner circumference of the inlet seal ring 855 is smaller than the maximum radial dimension of the hemispherical surface 853, thereby achieving the objective of correspondingly closing the passage inlet after the movement of the valve plug 85. Also, one end of the valve plug 85 facing the passage outlet is a flat surface 854, and a circumferential annular convex rib 857 is provided at the passage outlet position. The radial dimension of the inner circumference of the annular convex rib 857 is smaller than the radial dimension of the valve plug 85, thereby allowing the flat surface 854 of the valve plug 85 to make tight contact with the annular convex rib 857. A circumferential outlet seal ring 856 is provided coaxially on the flat surface 854 of the valve plug 85, projecting toward the passage outlet direction. The radial dimension of the outlet seal ring 856 is larger than the radial dimension of the inner circumference of the annular convex rib 857, thereby achieving the objective of correspondingly closing the passage outlet after the movement of the valve plug 85. The valve plug has two ends with different shapes, which prevents the valve plug from being installed in the wrong direction.

[0127] More preferably, to improve the sealing performance of the valve plug 85, the side of the annular convex rib 857 provided at the passage outlet that faces the inside of the passage is configured as an annular sphere. The aforementioned annular sphere is part of a sphere, and thus the annular sphere can use its gradually concave curved surface to press and seal the outwardly protruding outlet seal ring 856. The radial dimension of the inner circumference of the aforementioned annular sphere is smaller than the radial dimension of the outer circumference of the outlet seal ring 856, thereby ensuring that at least a portion of the outlet seal ring 856 is in contact with the annular sphere, achieving an effective seal between the valve plug 85 and the passage outlet. In addition, to prevent the valve plug 85 from becoming immobile at the outlet position, a columnar stopper projection 858 protruding toward the outlet may be installed at the center of the plane 854 of the valve plug 85. The axial height of the columnar stopper projection 858 is smaller than the height of the annular sphere, and the radial dimension of the outer circumference is larger than the radial dimension of the inner circumference of the annular convex rib 857.

[0128] As shown in Figures 2 to 11, an embodiment of the present invention further introduces a laundry additive dispensing device. The laundry additive dispensing device comprises a first dispensing channel 131 used to draw up a first laundry additive stored in a first liquid storage chamber 211, a second dispensing channel 132 used to draw up a second laundry additive stored in a second liquid storage chamber 212, and a main intake channel 10 for dispensing and / or taking in a laundry additive mixture to the outside, and has the aforementioned interlocking switching valve 8, the outlet of the first dispensing channel 131 and the outlet of the second dispensing channel 132 are in one-to-one correspondence with the first inlet 811 of the first passage 81 and the second inlet 821 of the second passage 82 of the interlocking switching valve 8 and communicate with each other, and the outlets 81 and 82 of the two passages of the interlocking switching valve 8 are in mutual communication with the main intake channel 10.

[0129] In the embodiment of the present invention, a first liquid absorption structure is installed on the first input water channel 131, and a second liquid absorption structure is installed on the second input water channel 132. The aforementioned liquid absorption structure may be any conventional structure that draws up the laundry additive contained in the corresponding liquid storage chamber 21 into the input water channel 13. For example, a negative pressure suction structure composed of a venturi tube, a suction pump, etc.

[0130] In the embodiments of the present invention, the explanation will be developed using an example in which the liquid absorption structure is a negative pressure suction structure. However, the present invention is not limited to the above-described structure in which a negative pressure suction structure is provided on the first input water channel 131 and the second input water channel 132, respectively, and the negative pressure ports 43 of the two negative pressure suction structures are in communication with each other, and when the intake water flow enters one input water channel 13, a negative pressure is formed in the other input water channel 13, thereby sucking up the laundry additive in the corresponding liquid storage chamber 21. By installing interlocking switching valves at the outlet positions of the two input water channels equipped in the negative pressure suction structure, the objective is achieved in which the outlet of the other input water channel closes in conjunction when one input water channel takes in water. This forms a sealed chamber in the other input water channel, achieving a remarkable technical advancement in which the input water channel improves the speed at which it sucks up the laundry additive in the liquid storage chambers that are in communication with each other.

[0131] Preferably, in the embodiment of the present invention, the third outlet 831 of the third outflow passage 83 of the interlocking switching valve 8 is in communication with the main intake water channel 10. As a result, the three outlets 812, 822, and 831 of the interlocking switching valve 8 are all in communication with the main intake water channel 10, and the intake water flow from either or a combination of the two input water channels 13 is introduced into the main intake water channel 10, thereby achieving the effect of introducing or supplying a laundry additive mixture into the washing machine tub.

[0132] In embodiments of the present invention, the control method for the aforementioned feeding device includes the following:

[0133] When the first laundry additive, which has been drawn up into the first input channel, is introduced, water is drawn into the first input channel / second input channel. The intake water flows into the first passage of the interlocking switching valve. The first valve plug in the first passage closes the first outlet of the first passage, and the valve plug in the second passage closes the second inlet of the second passage. The first laundry additive, together with the intake water flow, flows into the main intake channel from the second outlet of the second passage and is introduced to the outside.

[0134] When the second laundry additive, which has been drawn up into the second input channel, is introduced, water is drawn into the second input channel. The intake water flows into the second passage of the interlocking switching valve. The second valve plug in the second passage closes the second outlet of the second passage, and the first valve plug in the first passage closes the first inlet of the first passage. The second laundry additive, together with the intake water flow, flows into the main intake channel from the first outlet of the first passage and is introduced to the outside.

[0135] In embodiments of the present invention, the control method for the aforementioned feeding device includes the following:

[0136] When the first laundry additive is added, water is first drawn into the second input channel. The intake water flow closes the second outlet of the second passage and the first inlet of the first passage of the interlocking switching valve. The intake water flow flows into the main intake channel via the first outlet of the first passage and the third outlet of the third outflow passage, supplying water to the outside. At the same time, the outlet of the first input channel is closed, creating a sealed space within the first input channel. The intake water flowing into the second input channel is used to generate negative pressure at the position of the second negative pressure suction structure, and the negative pressure is transmitted into the first input channel via the second negative pressure port of the second negative pressure suction structure. The negative pressure in the first input channel is used to draw the first laundry additive stored in the first liquid storage chamber into the first input channel.

[0137] Subsequently, water is simultaneously drawn into the first and second input channels. The intake water flow closes both the first outlet of the first passage and the second outlet of the second passage of the interlocking switching valve, and opens the third outlet of the third outflow passage. Using the incoming water flow, the first laundry additive, which has been drawn up into the first input channel, is then flowed into the main intake channel via the third outlet and discharged to the outside.

[0138] When adding the second laundry additive, water is first drawn into the first input channel. The intake water flow closes the first outlet of the first passage and the second inlet of the second passage of the interlocking switching valve. The intake water flow flows into the main intake channel via the second outlet of the second passage and the third outlet of the third outflow passage, supplying water to the outside. At the same time, the outlet of the second input channel is closed, creating a sealed space within the second input channel. The intake water flow that has flowed into the first input channel is used to generate negative pressure at the position of the first negative pressure suction structure, and the negative pressure is transmitted into the second input channel via the first negative pressure port of the first negative pressure suction structure. The negative pressure in the second input channel is used to draw the second laundry additive stored in the second liquid storage chamber into the second input channel.

[0139] Subsequently, water is simultaneously drawn into the first and second input channels. The intake water flow closes both the first outlet of the first passage and the second outlet of the second passage of the interlocking switching valve, while opening the third outlet of the third outflow passage. Using the incoming water flow, the second laundry additive, which has been drawn up into the second input channel, is then flowed into the main intake channel via the third outlet and discharged to the outside.

[0140] In the embodiments of the present invention, the specific structure of the laundry additive dispensing device described above may be as follows.

[0141] As shown in Figures 1 to 9, an embodiment of the present invention introduces a detergent dispenser that is mounted on a washing machine. The aforementioned detergent dispenser 100 comprises a water case 1 and a detergent case 2 mounted inside the water case 1. The aforementioned detergent case 2 can be removed and opened by pulling it out by hand, and closed by pushing it inward. A liquid storage chamber 21 for storing detergent and laundry additives such as fabric softener is provided on the detergent case 2. The aforementioned liquid storage chamber 21 is composed of an independent chamber and may be detachably mounted on the detergent case 2, or it may be integrally installed on the detergent case 2 and be a liquid storage tank for storing laundry additives. An automatic dispensing module is further provided on the water case 1 and is used to draw up the laundry additives in the liquid storage chamber 21 into the water storage tank 11 of the water case 1. A water intake pipe is further connected to the water case 1, and the water intake pipe draws water into the water storage tank 11, mixing the drawn-up laundry additives with the water flow to form a laundry additive mixture. An outlet 14 is provided at the bottom of the water storage tank 11, allowing the laundry additive mixture and the intake water flow to flow out of the water case 1 through the outlet 14 and enter the washing tub of the washing machine.

[0142] In embodiments of the present invention, the automatic feeding module described above may be any of the conventional structures. In embodiments of the present invention, the automatic feeding module is configured as follows, but the scope of protection of the present invention is not limited to the following configuration.

[0143] A water channel is integrally provided on the water case 1. The aforementioned water channel comprises a first input water channel 131 and a second input water channel 132. The intake ends of the first input water channel 131 and the second input water channel 132 are connected to an intake pipe via an intake valve 5 and are used to introduce the water flow from the washing machine into the input water channel of the input device, either individually or simultaneously, in a controllable manner. A first negative pressure suction structure 41 is provided on the first input water channel 131, and a second negative pressure suction structure 42 is provided on the second input water channel 132. The negative pressure suction structure 4 can generate negative pressure at the negative pressure port position by utilizing the water flow that has entered the input water channel. The negative pressure ports 43 of the two negative pressure suction structures 4 are connected, and the first input water channel 131 is connected to the first liquid storage chamber 211, and the second input water channel 132 is connected to the second liquid storage chamber 212. The negative pressure of the negative pressure suction structure 4 acts on the other input water channel, allowing the laundry additive stored in the liquid storage chamber 21 connected to the input water channel to be drawn up. Subsequently, water is drawn into both input water channels simultaneously, and the intake water flows into the first and second input water channels at the same time, allowing the laundry additive drawn up in the previous step to mix with the intake water flow to form a laundry additive mixture.

[0144] In embodiments of the present invention, the negative pressure suction structure 4 described above may be any conventional structure that uses negative pressure to draw up laundry additives. For example, a venturi tube. The venturi tube is a straight tube and is divided into a narrowed diameter section, a straight section, and an expanded diameter section from the water intake end to the water outlet end. A negative pressure port 43 that penetrates the outside is drilled in the straight section, and the water flowing into the venturi tube forms a negative pressure at the negative pressure port 43, thereby achieving the effect of drawing up laundry additives stored in the liquid storage chamber 21 that communicates with the negative pressure port 43.

[0145] In embodiments of the present invention, the following configuration may be used to improve the efficiency of adding laundry additives after they have been drawn up, by enabling the laundry additives to be drawn up in a switchable manner using two input water channels 13.

[0146] The first negative pressure port 411 of the first negative pressure suction structure 41 and the second negative pressure port 421 of the second negative pressure suction structure 42 are in direct communication with each other via a pipeline. The intake end of the first input water channel 131 and the intake end of the second input water channel 132 are each in communication with the intake pipe 6 via one-to-one opposing intake valves 5. The outlet end of the first input water channel 131 and the outlet end of the second input water channel 132 are both in communication with the water storage tank 11 of the input device, thereby allowing the laundry additive mixture to be injected to the outside via the outlet 14 of the water storage tank 11. The first negative pressure suction structure 41 is connected in series near the intake end of the first input water channel 131, and the second negative pressure suction structure 42 is connected in series near the intake end of the second input water channel 132. The area near the outlet of the first input channel 131 is connected to the first liquid storage chamber 211, where the first laundry additive is stored. The area near the outlet of the second input channel 132 is connected to the second liquid storage chamber 212, where the second laundry additive is stored.

[0147] In an embodiment of the present invention, the water case 1 comprises a water storage tank 11 having a groove-like shape with an open front and an open top. An upper cover 12 is fitted and covers the open top of the water storage tank 11. The upper cover 12 has a hollow structure inside, and the hollow part inside constitutes a water channel integrally installed on the upper cover 12, and the water channel comprises at least one inlet channel 13. At least the lower part of the water storage tank 11 constitutes a water outlet 15 for introducing the laundry additive mixture into the washing tub of the washing machine, and the upper part constitutes a mounting space for the detergent case 2 to be assembled in a pull-out manner, and the liquid storage chamber 21 is installed inside the detergent case 2. Preferably, the detergent case 2 is configured with two parts, upper and lower, that are engaged with each other, and the hollow part inside constitutes at least one liquid storage chamber 21, which is used to accommodate different laundry additives. The upper part of the detergent case 2 is provided with an inlet for the user to inject laundry additives, and an openable and closable cover may be installed at the inlet position.

[0148] As shown in Figures 1 to 9, in the embodiment of the present invention, a fluid communication structure is provided between the water case 1 and the detergent case 2, and is used to enable fluid communication between the liquid storage chamber 21 and the input water channel 13 so as to be able to open and close. Any of the prior art structures may be used for the aforementioned fluid communication structure. Specifically, the fluid communication structure in the embodiment of the present invention is as follows: A first liquid conduit 160 is provided on the liquid storage chamber 21, the liquid inlet end of the first liquid conduit 160 is inserted into the bottom of the liquid storage chamber 21, and the liquid outlet end is drilled toward the side where the liquid storage chamber 21 is pushed into the water case 1. The liquid inlet end of the first liquid conduit 160 is located at the lowest liquid level of the liquid storage chamber 21. A second liquid conduit 170 is provided on the water case 1, and the liquid outlet end of the second liquid conduit 170 communicates with the input water channel 13 provided on the upper cover 12 of the water case 1. The liquid inlet end is located on the rear wall of the water case 1, facing into the water case 1, and is installed to be inserted coaxially with the liquid outlet end of the first liquid conduit 160 so that fluid communication is possible. After the detergent case 2 is pushed into the water case 1, the liquid outlet end of the first liquid conduit 160 is inserted into the liquid inlet end of the second liquid conduit 170, thereby creating fluid communication between the first liquid conduit 160 and the second liquid conduit 170.

[0149] As shown in Figure 8, in this embodiment of the present invention, the first liquid conduit 160 is a pipeline that extends horizontally at both ends, and the front end of the horizontal pipeline inserted into the liquid storage chamber 21 is the liquid inlet end. The liquid inlet end communicates with the bottom of the liquid storage chamber 21 and a position lower than the lowest liquid level in the liquid storage chamber 21, while the rear end extends out of the liquid storage chamber 21 and constitutes the liquid outlet end of the first liquid conduit 160.

[0150] In an embodiment of the present invention, the liquid outlet end of the first fluid conduit 160 is inserted correspondingly into the liquid inlet end of the second fluid conduit 170. The outer wall of the first fluid conduit 160 is in contact with the inner wall of the second fluid conduit 170, and a sealing ring of at least one turn is provided. This creates a seal between the two fluid conduits after insertion, preventing the additive from leaking through the gap between them. Furthermore, to ensure that detergent does not leak from the first fluid conduit 160 or the second fluid conduit 170 after the detergent case 2 is pulled out, a switching valve may be provided at the liquid outlet end of the first fluid conduit 160 and / or the liquid inlet end of the second fluid conduit 170. The switching valve is used to close the corresponding end of the fluid conduit after the detergent case 2 is pulled out and to create fluid communication between the two inserted fluid conduits after the detergent case 2 is pushed in.

[0151] In embodiments of the present invention, the intake valve 5 may be a control valve individually installed at the intake end of each input water channel 13, capable of correspondingly controlling the opening and closing of the corresponding input water channel 13. In this case, the first intake valve 51 is connected to the intake end of the first input water channel 131, the second intake valve 52 is connected to the intake end of the second input water channel 132, and the third intake valve 53 is connected to the intake end of the third input water channel 133, with the inlets of each intake valve communicating with the water intake port 16 of the washing machine. Alternatively, it may be a switching valve having one inlet and multiple outlets, each outlet communicating with the corresponding input water channel. In this case, the valve plug of the intake valve 5 is used to control the water intake port 16 and each outlet to communicate with each other either selectively or simultaneously, and the inlet of the intake valve 5 constitutes the water intake port 16 of the washing machine and communicates with the water source via a pipeline.

[0152] In an embodiment of the present invention, a removable detergent case 2 is installed inside the water case 1. Multiple liquid storage chambers 21 are installed on the detergent case 2, each of which is for storing different types of laundry additives. These laundry additives include detergents, fabric softeners, disinfectants, etc. Each liquid storage chamber 21 is in fluid communication with each input water channel 13 in a one-to-one correspondence. Here, detergent is stored in the first liquid storage chamber 211, and the first liquid storage chamber 211 is in communication with the first input water channel 131.

[0153] In this embodiment of the present invention, an additional input chamber 31 is provided on the input device to improve the uniformity of the mixing of the drawn-up laundry additive and the intake water. As a result, the outlet of the input water channel 13 communicates with the input chamber 31, allowing the laundry additive and the intake water flow to flow into the input chamber 31, mix thoroughly, and then flow to the outlet 15 of the water storage tank 11 and out through the outlet 14. This significantly improves the uniformity of the mixing of the laundry additive. In this embodiment of the present invention, an input case 3 that can be pulled out is installed inside the water case 1. The input case 3 has at least one input chamber 31. The top of the input chamber 31 is open, and an opening is provided at the bottom. The aforementioned opening directly constitutes the outlet 14 of the water case 1. Alternatively, the aforementioned opening is connected to the outlet 15 installed at the bottom of the water case 1 and communicates with the outlet 14 of the water case 1. A siphon section 32 is provided at the bottom opening of the input chamber 31. This siphon section 32 prevents unmixed additives from flowing out and is used to drain the mixed additive solution after mixing, thereby improving the uniformity of the mixing between the drawn-up laundry additives and the intake water flow. The aforementioned siphon section 32 may be any of the conventional siphon structures that can automatically activate the siphon drainage effect when the intake water level reaches a certain height. For example, the specific structure of the siphon section 32 is as follows: As shown in Figure 9, an inner sleeve pipe is provided extending vertically upward at the opening, and an outer sleeve pipe is coaxially fitted to the outside of the inner sleeve pipe. The top end of the outer sleeve pipe is closed, and the lower end has a gap between it and the bottom wall of the input chamber 31. The lower end of the inner sleeve pipe communicates with the water outlet section 15 below the input case 3, and there is a distance between the upper end and the closed top end of the outer sleeve pipe, thereby connecting the gap between the inner sleeve pipe and the outer sleeve pipe. The gap between the inner sleeve pipe and the outer sleeve pipe, as described above, constitutes a siphon flow path through which the input chamber and the outlet section communicate with each other. By utilizing the siphon section 32 with the above structure, a siphon effect is generated when the liquid level in the input chamber 31 is higher than the height of the inner sleeve pipe, allowing the laundry additive mixture in the input chamber 31 to be injected to the outside.Furthermore, in order to ensure that the inner and outer cylinders of the siphon section 32 can be installed with a gap between them, multiple support ribs may be placed in the gap between the inner sleeve pipe and the outer sleeve pipe. Each support rib does not cover any of the water flow cross-sections of the siphon flow path, and a portion of the support rib abuts against the inner wall of the outer sleeve pipe, while a portion abuts against the outer wall of the inner sleeve pipe, thereby enabling assembly in which the inner and outer sleeve pipes are supported with a gap between them.

[0154] Furthermore, an injection chamber is provided on the upper cover 12 in the upper region of the input chamber 31. The injection chamber communicates with the outlet end of the input water channel 13. Multiple injection nozzles are arranged on the bottom wall of the injection chamber, and each nozzle is used to uniformly inject the intake water flow and the added laundry additive into the input chamber.

[0155] In the embodiments of the present invention, the explanation will be based on an example in which two dispensing systems for dispensing detergent and fabric softener, respectively, are provided on the dispensing device 100.

[0156] As shown in Figures 1 to 9, a detergent case 2 is installed inside the water case 1 of the dispensing device 100. Two liquid storage chambers 21 are installed inside the detergent case; the first liquid storage chamber 211 is used to store detergent, and the second liquid storage chamber 212 is used to store fabric softener. A first dispensing channel 131 and a second dispensing channel 132 are provided on the water case 1, and intake valves 5 are connected to the intake ends of the two dispensing channels. The inlets of each intake valve 5 are in communication with the water source of the washing machine.

[0157] A first injection chamber 1311 is connected to both the outlet end of the first input water channel 131 and the outlet end of the second input water channel 132, and multiple first injection ports 1312 are drilled in the bottom of the first injection chamber 1311. Each first injection port 1312 is located above the first input chamber 311 and is used to connect the outlet of the first input water channel 131 to the first input chamber 311. As a result, the drawn-up detergent enters the first input chamber 311 via the first input water channel 131, and the drawn-up fabric softener also enters the first input chamber 311 via the second input water channel 132.

[0158] An opening is provided in the bottom wall of the first input chamber 311, and a siphon section 32 is provided at the opening. As a result, detergent and water, or fabric softener and water, that enter the first input chamber 311 mix, and when the liquid level exceeds the operating liquid level of the siphon section 32, the siphon effect is activated, and the mixed liquid in the input chamber is discharged from the first input chamber 311. The opening in the bottom wall of the first input chamber 311 is in communication with the water outlet section 15 provided at the bottom of the water storage tank 11 of the water case 1 below, and a water outlet 14 is provided at the lowest position of the bottom wall of the water outlet section 15. As a result, the mixed liquid is discharged to the outside from the water outlet 14 of the water case 1 via the water outlet section 15 of the water storage tank 11 and put into the washing drum of the washing machine.

[0159] In an embodiment of the present invention, a detergent case 2 and a dispensing case 3, which can be pulled out, are installed inside the water case 1. The detergent case 2 is provided with at least one liquid storage chamber 21, and the dispensing case 3 is provided with at least one dispensing chamber 31. The detergent case 2 and the dispensing case 3 are installed in the water tank 11, arranged alternately on the left and right sides, and can each be pulled out from the front of the water tank 11. In this embodiment of the present invention, the explanation will be given using an example in which a first dispensing chamber 311 and a second dispensing chamber 312 are installed on the dispensing case. The first dispensing chamber 311 is for manually adding detergent, and the second dispensing chamber 312 is for manually adding fabric softener. A third dispensing channel 133 is further integrally provided on the water case 1, and the outlet end of the third dispensing channel 133 communicates with the second injection chamber 1321. The bottom wall of the second injection chamber 1321 is provided with a plurality of second injection ports 1322, which are located above the second dispensing chamber 312 and are drilled toward the inside of the second dispensing chamber 312. The bottom wall of the first injection chamber 1311 is provided with a plurality of first injection ports 1312, which are located above the first input chamber 311 and are drilled into the first input chamber 311.

[0160] In the embodiment of the present invention, a liquid level sensor is provided in the input chamber 31 of the input case 3 and is used to detect the amount of additive in the input chamber 31. The aforementioned liquid level sensor may have any conventional structure, but it must be able to detect the liquid level and / or volume in the input chamber.

[0161] In an embodiment of the present invention, a water intake port 16 is provided on the water case 1. The water intake port 16 constitutes the water intake end of the water inlet channel 13 which is integrally installed on the water case 1. The water intake port 16 is connected to the inlet of a water intake valve 5, which is attached in a one-to-one correspondence to the water intake end of each water inlet channel 13, and the inlets of the water intake valves 5 communicate with the water intake source of the washing machine. The water intake source of the washing machine is generally the tap water in the user's home. The water intake valve 5 can control the opening and closing of the water intake port 16 and each water inlet channel 13, and is used to control the opening and closing of the supply of tap water to the water case 1.

[0162] In the daily lives of washing machine users, a lot of wastewater can be generated. For example, some of this wastewater, such as rice rinsing water, vegetable washing water, and floor cleaning water, can be reused in washing machines. The aforementioned wastewater is generally referred to as "secondary supply water" and can be reused for washing, rinsing, and other processes in washing machines. To enable the use of secondary supply water in washing machines, users typically collect the aforementioned secondary supply water in a water collection container and then pump it into the washing machine's water intake line via a pipeline equipped with a suction pump, thereby reusing the secondary supply water in their washing machines.

[0163] As shown in Figures 1 to 9, in the embodiment of the present invention, a water intake pump 7 is additionally installed on the washing machine, and the water intake pump 7 is mounted on the water supply device 100. The water intake pump 7 communicates with the first water supply channel 131 and the second water supply channel 132 of the water supply device 100. As a result, the water intake pump 7 can draw in the secondary supply water it suctions and delivers directly into the washing drum of the washing machine via the water supply device 100, thereby achieving the effect of effectively utilizing the secondary supply water.

[0164] By connecting the suction pump in series to the first or second water inlet channel of the water supply device, the water supply device can controllly supply secondary water via the suction pump, and the intake pipe can draw in tap water. This achieves a remarkable technological advancement in that the water supply device integrates two different water supply modes. Furthermore, the tap water supplied from the intake pipe can be effectively used to fill the pump chamber of the suction pump, thereby achieving a remarkable technological advancement in that the suction pump is automatically controlled to meet its operating requirements.

[0165] As shown in Figures 1 to 9, an embodiment of the present invention introduces a washing machine dispensing device 100 in which an externally connected water intake pump is integrated. The dispensing device 100 comprises a water case 1 provided with a water storage tank 11 for drawing water into the washing tub of a washing machine, a liquid storage chamber 21 installed inside the water case 1 for storing a laundry treatment agent, and a negative pressure suction structure installed on the water case 1, wherein the negative pressure port 43 of the negative pressure suction structure 4 is connected to the liquid storage chamber 21, and the negative pressure suction structure 4 is connected in series to a first dispensing water channel 131 or a second dispensing water channel 132 provided on the water case 1, and draws the laundry treatment agent from the liquid storage chamber 21 into the dispensing water channel 13 integrally installed on the water case 1, then enters the water storage tank 11 together with the water intake water flowing into the dispensing water channel 13, mixes in the water storage tank 11 to form a laundry additive mixture, and then enters the washing tub of the washing machine through the water outlet 14 of the water case 1, thereby realizing the function of dispensing laundry additives or drawing water into the washing machine. The outlet 14 of the dispensing device communicates with the dispensing channel 13, the intake 16 is connected to the intake valve 5, and the intake 16 communicates with the washing machine's tap water tap in a way that allows for opening and closing control. The suction pump 7 communicates with the first dispensing channel 131 and / or the second dispensing channel 132, and is provided with a secondary supply water inlet 73 that is in fluid communication with an externally connected secondary supply water source in a way that allows for opening and closing control. It is used to introduce the intake water flow, which consists of washing machine tap water supplied from the intake valve 5 or secondary supply water supplied from the suction pump 7, into the storage tank 11. Therefore, the dispensing device can use tap water or secondary supply water to wash away and dispense the laundry additives that have been introduced into the intake channel, thereby achieving the effect of introducing laundry additives to the outside by adopting different water intake modes.

[0166] In an embodiment of the present invention, the suction pump 7 is provided with an inlet 71 and an outlet 72. Both the inlet 71 and the outlet 72 communicate with each other at the highest point of the pump chamber 74 of the suction pump 7. This ensures that the intake water can flow into the input channel 13 of the input device 100 only when the pump chamber 74 of the suction pump 7 is filled. The secondary supply water inlet 73 is located at the top of the pump chamber 74 of the suction pump 7 and is drilled upwards. The secondary supply water inlet 73 communicates with the secondary supply water source via a pipeline equipped with a check valve. The check valve is used to ensure that the water flow in the pipeline flows only in the direction of the secondary supply water inlet 73. Preferably, to ensure the direction of water flow in the intake pipe 6, a check valve is provided on the input channel 13 upstream of the suction pump 7 and is used to control the secondary supply water that has flowed into the pump chamber 74 so that it flows out only from the outlet 72 of the suction pump 7, thereby preventing backflow in the direction of the intake valve 5.

[0167] In this embodiment of the present invention, the suction pump 7 is mounted above the water case 1 and located on one side of the water case 1. This ensures that water in the input channel 13 of the input device 100 cannot flow back into the pump chamber 74 of the suction pump 7. Both the intake valve 5 and the suction pump 7 are mounted above the water case 1 and located on opposite left and right sides of the water case 1, respectively. This achieves the objective of preventing water in the input channel 13 of the input device 100 from flowing back towards the intake valve 5. Preferably, to further avoid the occurrence of backflow of water within the input device, the inlet 71 and outlet 72 of the suction pump 7 and the outlet of the intake valve 5 are all located above the top wall of the water case 1.

[0168] In an embodiment of the present invention, the integrated water channel provided on the upper cover 12 of the water case 1 further comprises a main intake water channel 10. The intake end of the main intake water channel 10 communicates with the intake ends of the first inlet water channel 131 and the second inlet water channel 132, respectively. The point of communication between the main intake water channel 10 and the first inlet water channel 131 is located between the first intake valve 51 and the first negative pressure suction structure 41, and the point of communication between the main intake water channel 10 and the second inlet water channel 132 is located between the second intake valve 52 and the second negative pressure suction structure 42. The outlet end of the main intake water channel 10 communicates with the first injection chamber 1311. Furthermore, in order to prevent the water flow in the main intake channel 10 from flowing back into the inlet channel 13, check valves are provided at the points where the first inlet channel 131 and the second inlet channel 132 communicate with the main intake channel 10 to prevent backflow of water.

[0169] The outlets of the first input channel 131 and the second input channel 132 are in mutual communication with the main intake channel 10 via the aforementioned interlocking switching valve 8. As a result, the laundry additive mixture formed in the input channel 13 enters the main intake channel 10 directly, flows together with the intake water flow from the first injection chamber 1311 to the first input chamber 311, enters the outlet section 15 at the bottom of the water storage tank 11, and is dispensed into the washing machine tub from the outlet 14. The first, second, and third outlets of the interlocking switching valve 8 are all in mutual communication with the main intake channel 10. The first inlet of the interlocking switching valve and the outlet of the first input channel are in mutual fluid communication, and the second inlet and the outlet of the second input channel are in mutual fluid communication. This achieves the effect of allowing the intake water flow and laundry additive mixture from two different input channels to flow into the interlocking switching valve 8, respectively.

[0170] Furthermore, in order to prevent the water pressure in the main intake channel 10 from becoming too high due to the intake water and laundry additive mixture entering the main intake channel 10 from the first input channel 131 and the second input channel 132 entering too quickly, an overflow outlet 17 may be installed on the main intake channel 10. The overflow outlet 17 directly connects the main intake channel 10 and the water storage tank 11, which are located on the upper cover 12. The overflow outlet 17 is installed on the bottom wall of the channel near the point where the main intake channel 10 and the first input channel 131 and the second input channel 132 are connected.

[0171] The inlet 71 of the suction pump 7 is connected to the main intake channel, and the outlet 72 is connected to the first injection chamber 1311 via a connecting pipe. As a result, the suction pump 7 is connected in parallel to the main intake channel 10, and the water flow when the dispensing device dispenses detergent or rinse agent can flow through the suction pump 7, filling the pump chamber 74 of the suction pump 7. This ensures that the suction pump 7 can directly draw water after dispensing is complete, and that secondary supply water can be drawn in and used for the dispensing device.

[0172] In this embodiment of the present invention, a washing machine is introduced. The washing machine may be any conventional garment processing equipment capable of processing clothes. These may include, for example, a drum-type washing machine, a swirl-type washing machine, a washer-dryer, or a dryer. In this embodiment of the present invention, for the sake of explanation, the discussion will be based on the example of a swirl-type washing machine, but the present invention is not limited to a swirl-type washing machine. As shown in Figure 1, in this embodiment of the present invention, the top of the washing machine's casing is a control panel base 200, and inside the casing is a washing tub with an axis extending vertically and a tub opening at the top. The control panel base 200 is located above the tub opening of the washing tub, and the detergent dispensing device 100 is mounted on the control panel base 200. The outlet 14 of the water case 1 of the detergent dispensing device 100 is drilled toward the tub opening of the washing tub. This allows the water intake flow of the washing machine, the added laundry additives, etc., to be dispensed into the washing drum via the outlet 14 of the dispensing device.

[0173] In embodiments of the present invention, the control method for the washing machine described above includes the following:

[0174] When adding the first laundry additive stored in the first liquid storage chamber, water is first drawn into the second input channel, and negative pressure is generated using the incoming water flow to draw the first laundry additive into the first input channel. Simultaneously, an interlocking switching valve is used to close the outlet end of the first input channel using the incoming water flow, so that the negative pressure in the first input channel can draw up the first laundry additive stored in the first liquid storage chamber with maximum efficiency.

[0175] Subsequently, water is simultaneously drawn into the first and second input channels, and the resulting water flow is used to transfer the first laundry additive, which has been drawn up in the first input channel, into the storage tank and then into the washing machine tub.

[0176] When adding the second laundry additive stored in the second liquid storage chamber, water is first drawn into the first input channel, and the incoming water flow is used to generate negative pressure, drawing the second laundry additive into the second input channel. Simultaneously, an interlocking switching valve is used to close the outlet end of the second input channel using the incoming water flow, so that the negative pressure in the second input channel can draw up the second laundry additive stored in the second liquid storage chamber with maximum efficiency.

[0177] Subsequently, water is simultaneously drawn into the first and second input channels, and the resulting water flow is used to transfer the second laundry additive, which has been drawn up into the second input channel, into the storage tank and then into the washing machine tub.

[0178] When the first laundry additive, which has been manually added to the first input chamber, is introduced, water is simultaneously drawn into the first input channel and the second input channel. The drawn water enters the first input chamber via the first injection chamber, and the first laundry additive, which has been manually added to the first input chamber, is poured into the storage tank and then into the washing machine tub.

[0179] When manually adding the second laundry additive to the second input chamber, water is drawn into the third input channel. The drawn water enters the second input chamber via the second injection chamber, and the manually added second laundry additive flows into the storage tank and into the washing machine tub.

[0180] In the embodiment of the present invention, when the washing machine draws water using secondary water supply, first, the water intake valve is opened according to the method described above, the water intake pump is stopped, the first laundry additive / second laundry additive is added, and when the addition is complete, tap water is filled into the pump chamber of the water intake pump.

[0181] Next, the intake valve is closed and the suction pump is started. The suction pump draws secondary supply water into the pump room via the secondary supply water inlet, and then flows it into the storage tank via the input water channel and the main intake water channel, thereby achieving the objective of drawing water into the washing machine tub.

[0182] In embodiments of the present invention, when the washing machine draws water using secondary supply water, it is necessary to ensure that water is injected into the pump chamber of the suction pump until it is full. To ensure the above condition, the control method of the washing machine further includes the following:

[0183] When the washing machine uses secondary water supply to draw water, it first opens the intake valve and stops the suction pump. The intake pipe allows tap water to flow into the first and second input channels. The water flowing through the first and second input channels reaches the reservoir, and the intake water flowing through the input channels flows through the suction pumps, which are connected in parallel, and continues to flow until the pump chambers of the suction pumps are filled with tap water.

[0184] Next, the intake valve is closed and the suction pump is started. The suction pump draws secondary supply water into the pump room via the secondary supply water inlet, and then allows it to flow into the storage tank via the intake pipe and suction channel.

[0185] In embodiments of the present invention, the washing machine control method further includes the following:

[0186] When the washing machine uses secondary water supply to draw water, the intake valve is first opened, the suction pump is stopped, and after a set time t1 has elapsed, the intake valve is then closed and the suction pump is started. The suction pump in this invention can only start operating when water has been injected until the pump chamber is full. In addition, in this invention, the suction pump is directly connected in series to the intake pipe of the input device, so that when the input device normally draws in tap water, the tap water flows through the pump chamber of the suction pump, maintaining the pump chamber of the suction pump in a full state under normal conditions. As a result, the suction pump can start operating immediately after receiving a command, significantly saving the time required for water intake. Furthermore, in order to ensure that the suction pump is operational before starting the suction pump and to avoid the situation where water has not been injected until the pump chamber of the suction pump is full, the control method in this invention, in particular, at the timing of starting secondary water supply intake, first opens the intake valve, allowing tap water to flow through the intake pipe and the suction pump into the washing drum of the washing machine. The system uses flowing tap water to ensure that the pump chamber of the suction pump is filled to capacity. This enables the suction pump to be automatically driven and started.

[0187] In embodiments of the present invention, the control method for the washing machine described above includes the following:

[0188] The laundry additive dispenser acquires the pre-set amount to be dispensed and the amount of laundry additive in the dispenser chamber.

[0189] Formula: Differential input amount = Pre-set input amount - The differential input amount is obtained according to the amount of additive in the manual input module.

[0190] Water is drawn into the other input channel opposite to the selected input chamber, and the negative pressure created by the water intake is used to draw the difference in the amount of laundry additive from the storage chamber into the selected input chamber.

[0191] Water is drawn in simultaneously into two input channels, mixed with laundry additives inside the input chamber, and then released to the outside.

[0192] The aforementioned configuration allows for the automatic dispensing module to automatically replenish and dispense laundry additives that have been manually added by the user, significantly improving the accuracy of additive dispensing. Furthermore, by using two different dispensing modules, it is possible to synchronize and accurately dispense laundry additives into the washing machine in a coordinated manner, diversifying the functionality of the dispensing device and significantly improving the product's performance.

[0193] In embodiments of the present invention, the control method for the detergent dispensing device further includes the following:

[0194] Determine whether the amount of laundry additive in the dispenser is greater than the pre-set amount.

[0195] If there is a large amount, water is drawn directly into the two input channels of the water case, mixed with the laundry additive in the input chamber, and then released to the outside.

[0196] If the amount is insufficient, water is drawn into the other input channel opposite to the selected input chamber, and the negative pressure created by the water intake is used to draw the difference in the amount of laundry additive from the storage chamber into the selected input chamber. Then, using both input channels, water is drawn into the water case simultaneously, and the laundry additive in the input chamber is dispensed to the outside.

[0197] This prevents situations where, even if there is an excessive amount of laundry additive inside the dispenser, more is still drawn up from the storage chamber and dispensed. This significantly improves the accuracy of the amount of laundry additive dispensed, effectively preventing the accidental dispensing of too much laundry additive, which would lead to waste and reduced washing effectiveness.

[0198] In embodiments of the present invention, the control method for the detergent dispensing device further includes the following:

[0199] The laundry additive dispenser determines the type of laundry additive to be added.

[0200] The amount of laundry additive in the dispenser corresponding to the determined type of laundry additive is detected.

[0201] Formula: Differential input amount = Pre-set input amount - The differential input amount is obtained according to the amount of additive in the manual input module.

[0202] The system controls the other unconnected input channel to draw water from the determined type of laundry additive, and the determined type of laundry additive in the corresponding storage chamber is pumped and transported to the corresponding input channel until the amount of laundry additive pumped up reaches the differential input amount.

[0203] Subsequently, water is drawn in simultaneously into two input channels, and the intake water flow and laundry additive are introduced into the corresponding input chambers for mixing to form a laundry additive mixture. This mixture is then poured into the washing drum of the washing machine via the outlet of the water case.

[0204] In the embodiments of the present invention, the explanation will be based on an example in which the dispensing device 100 has two sets of dispensing chambers and two sets of dispensing channels and liquid storage chambers, and these work together to dispense detergent and fabric softener.

[0205] The specific operating modes of the dispensing device when dispensing detergent are as follows:

[0206] In step S111, the liquid level in the first input chamber is detected, and it is determined whether the detected value is smaller than the preset input amount. If it is smaller, step S112 is performed. If it is not smaller, step S114 is performed.

[0207] Step S112, Formula: Differential input amount = Pre-set input amount - Obtain the differential input amount according to the detected value.

[0208] In step S113, water is drawn into the second input channel, and the detergent stored in the first storage chamber is drawn into the first input channel. Once the amount of detergent drawn up reaches the differential input amount, step S114 is executed.

[0209] Step S114: Water is simultaneously drawn into the first and second input channels, and the drawn-up detergent is poured into the first input chamber.

[0210] Step S115: The intake water stream and detergent are mixed in the first input chamber to form a detergent mixture.

[0211] In step S116, water intake continues until the liquid level in the first input chamber exceeds the working liquid level of the siphon section. The detergent mixture in the first input chamber flows out to the outlet section below the water storage tank and is injected into the washing drum of the washing machine through the outlet located above the outlet section. This achieves the effect of both adding detergent and taking water into the washing machine.

[0212] The specific operating modes of the dispenser when dispensing fabric softener are as follows:

[0213] In step S211, the liquid level in the second input chamber is detected, and it is determined whether the detected value is smaller than the preset input amount. If it is smaller, step S212 is executed. If it is not smaller, step S214 is executed.

[0214] Step S212, Formula: Differential input amount = Pre-set input amount - Detected value. Obtain the differential input amount according to this formula.

[0215] In step S213, water is drawn into the first input channel, and the detergent stored in the second liquid storage chamber is drawn into the second input channel. Once the amount of fabric softener drawn up reaches the differential input amount, step S214 is executed.

[0216] In step S214, water is simultaneously drawn into the first and second input channels, and the drawn-up fabric softener is poured together into the second input chamber.

[0217] Step S215: The intake water stream and fabric softener are mixed in the second input chamber to form a fabric softener mixture.

[0218] In step S216, water intake continues until the liquid level in the second input chamber exceeds the working liquid level of the siphon section. The fabric softener mixture in the second input chamber flows out to the outlet section below the water tank and is injected into the washing drum of the washing machine through the outlet located above the outlet section. This achieves the effect of both adding fabric softener and taking out water from the washing machine. [Examples]

[0219] As shown in Figures 12 to 21, an embodiment of the present invention introduces a laundry additive dispensing device. This dispensing device is mounted on a washing machine and used to dispense laundry additives into the washing drum of the washing machine. The aforementioned detergent dispensing device 100 comprises a water case 1 provided with an intake channel 13 for introducing an intake water flow and an outlet 14 for dispensing laundry additives to the outside, a liquid storage chamber 21 containing laundry additives, an automatic dispensing module 101 used to draw up the laundry additives in the liquid storage chamber 21 into the intake channel 13 installed on the water case 1, and a manual dispensing module 102 connected to the outlet of the intake channel 13 and the outlet 14 of the water case 1, respectively, which allows the user to manually add laundry additives, and which uses the intake water flow to dispense the manually added laundry additives from the outlet of the water case 1, and / or dispenses the additives in the liquid storage chamber 21 drawn up by the automatic dispensing module 101 together with the intake water flow from the outlet 13 of the water case 1.

[0220] The aforementioned configuration integrates both automatic and manual dispensing functions for laundry additives into the washing machine's dispensing device, diversifying the dispensing methods. Furthermore, the manual dispensing module allows for the external dispensing of additives dispensed by the automatic dispensing module. This significantly simplifies the complexity of the device, as it can handle two dispensing modes with just a single dispensing outlet.

[0221] In an embodiment of the present invention, the manual dispensing module 102 includes a dispensing case 3 that is installed inside the water case 1 and can be pulled out. The dispensing case 3 has a dispensing chamber 31, the top of which is open and the bottom of which has an opening. The aforementioned opening directly constitutes the water outlet 14 of the water case 1, or the aforementioned opening communicates with a water outlet 15 installed at the bottom of the water case 1, with the water outlet 14 of the water case 1 being located at the lowest position of the water outlet.

[0222] In embodiments of the present invention, a siphon section 32 is provided at the bottom opening of the input chamber 31 to ensure that the laundry additive manually added by the user to the input chamber 31 does not automatically flow out from the bottom opening when the input case is pulled out. This siphon section 32 is used to prevent unmixed additives from flowing out and to allow the mixed additive liquid to flow out. The aforementioned siphon section 32 may be any of the prior art siphon structures that can automatically activate the siphon drainage effect when the intake water level reaches a certain height. For example, the specific structure of the siphon section 32 is as follows: As shown in Figure 21, an inner sleeve pipe extending vertically upward is provided at the opening, and an outer sleeve pipe is coaxially fitted to the outside of the inner sleeve pipe. The top end of the outer sleeve pipe is closed, and the lower end has a gap between it and the bottom wall of the input chamber 31. The lower end of the inner sleeve pipe communicates with the water outlet section 15 below the input case 3, and there is a distance between the upper end and the closed top end of the outer sleeve pipe, thereby connecting the gap between the inner sleeve pipe and the outer sleeve pipe. The gap between the inner and outer sleeve pipes described above constitutes a siphon flow path through which the input chamber and the outlet section communicate fluidly with each other. By utilizing the siphon section 32 with the above structure, a siphon effect is generated when the liquid level in the input chamber 31 is higher than the height of the inner sleeve pipe, allowing the laundry additive mixture in the input chamber 31 to be injected to the outside. In addition, to ensure that the inner and outer cylinders of the siphon section can be installed with a gap between them, multiple support ribs may be placed in the gap between the inner and outer sleeve pipes. Each support rib does not cover any of the water flow cross-sections of the siphon flow path, and a part of the support rib abuts the inner wall of the outer sleeve pipe, while a part abuts the outer wall of the inner sleeve pipe, thereby enabling assembly in which the inner and outer sleeve pipes are supported with a gap between them.

[0223] As shown in Figures 12 to 21, in the embodiment of the present invention, the water case 1 includes a water storage tank 11. The water storage tank has a grooved structure with an open top and an open front. An upper cover 12 is engaged with the top of the water storage tank 11, and the input case 3 is installed inside the water storage tank 11 so as to be removable to the outside. At least one input chamber 31 is provided on the input case 3, and the input chamber 31 has a grooved structure with an open top. An intake water channel 13 is integrated inside the upper cover 12, the inlet of the intake water channel 13 is in communication with the water intake pipe 6 of the washing machine, and the outlet is drilled above the opening of the input chamber 31 and is used to allow the water intake flow of the washing machine to flow into the input chamber 31. Preferably, an outlet chamber is provided on the upper cover 12 in the upper region of the input chamber 31. The outlet chamber constitutes the outlet end of the water intake water channel 13. Multiple outlets are located on the bottom wall of the water outlet chamber, allowing the intake water flow and the added laundry additive to be uniformly injected into the input chamber 31 using each outlet.

[0224] As shown in Figures 12 to 21, in embodiments of the present invention, the automatic dispensing module 101 comprises a detergent case 2 that is removable from the water case 1 and has a liquid storage chamber 21 installed inside it, and a pump 04 mounted on the water case 1, the inlet of which communicates with the liquid storage chamber 21 and the outlet of which communicates with the intake water channel 13 integrally installed on the upper cover 12 of the water case 1. Preferably, in order to prevent the intake water flow in the dispensing device from flowing back into the pump 04, the pump 04 is generally installed above the water case 1 and higher than the upper cover 12 of the water case 1, and it is ensured that the outlet of the pump 04 is higher than the intake water channel 13.

[0225] In an embodiment of the present invention, a detergent case 2 and a dispensing case 3, which can be pulled out, are installed inside the water case 1. The detergent case 2 is provided with at least one liquid storage chamber 21, and the dispensing case 3 is provided with at least one dispensing chamber 31. The detergent case 2 and the dispensing case 3 are installed in the water tank 11, arranged alternately on the left and right sides, and can each be pulled out from the front of the water tank 11.

[0226] In the embodiment of the present invention, a liquid level sensor is provided in the input chamber 31 of the input case 3 and is used to detect the amount of additive in the input chamber 31. The aforementioned liquid level sensor may have any conventional structure, but it must be able to detect the liquid level and / or volume in the input chamber.

[0227] In an embodiment of the present invention, the washing machine dispensing device 100 comprises a plurality of manual dispensing modules 102 and a plurality of automatic dispensing modules 101. Each automatic dispensing module 101 is connected to a corresponding manual dispensing module 102 in a one-to-one correspondence and is for dispensing different types of laundry additives.

[0228] In an embodiment of the present invention, the input case 3 has a plurality of input chambers 31, each used for inputting different types of laundry additives. The detergent case 2 has a plurality of liquid storage chambers 21, each storing a type of laundry additive that corresponds one-to-one with the input chamber. Each liquid storage chamber 21 communicates with a corresponding input chamber 31 via a corresponding pump 04 and a corresponding water intake channel 13, and is used to automatically pump different types of laundry additives into the corresponding input chambers 31.

[0229] In an embodiment of the present invention, the explanation will be based on an example in which the dispensing device 100 has two sets of automatic dispensing modules and two sets of manual dispensing modules, and the first automatic dispensing module 111 and the first manual dispensing module 112 work together to dispense detergent, and the second automatic dispensing module 121 and the second manual dispensing module 122 work together to dispense fabric softener.

[0230] As shown in Figures 12 to 21, a detergent case 2 is installed inside the water case 1 of the dispensing device 100. Two liquid storage chambers 21 are installed inside the detergent case; the first liquid storage chamber 211 is used to store detergent, and the second liquid storage chamber 212 is used to store fabric softener. A first pump 041 and a second pump 042 are provided on the water case 1. The inlet 051 of the water intake valve 5 is in communication with the water source of the washing machine, the first outlet 052 is in communication with the first water intake channel 0131 installed on the water case via the first water intake pipe 61, and the second outlet 053 is in communication with the second water intake channel 0132 installed on the water case 1 via the second water intake pipe 62. A suction pump 7 is connected in series on the first water intake pipe 61. Furthermore, the first hose 63, connecting fitting 66, second hose 64, suction pump 7, and third hose 65 are connected at their ends in order to form the first intake pipe 61, and the second intake pipe 62 is directly made up of a single hose. An opening is provided in the center of the first intake channel 0131, and this opening communicates with the outlet of the first pump 041, and the inlet of the first pump 041 is in fluid communication with the first liquid storage chamber 211. An opening is provided in the center of the second intake channel 0132, and this opening communicates with the outlet of the second pump 042, and the inlet of the second pump 042 is in fluid communication with the second liquid storage chamber 212.

[0231] A first outlet chamber 01311 is provided at the outlet end of the first intake channel 0131, and a number of first outlets 01312 are drilled at the bottom of the first outlet chamber 01311. Each of the first outlets 01312 is located above the first input chamber 311 and is used to connect the outlet of the first intake channel 0131 and the first input chamber 311 to each other. This allows the pressurized detergent to enter the first input chamber 311 via the first intake channel 0131. A second outlet chamber 01321 is provided at the outlet end of the second intake channel 0132, and a number of second outlets 01322 are drilled at the bottom of the second outlet chamber 01321. Each of the second outlets 01322 is located above the second input chamber 312 and is used to connect the second outlets 01322 of the second intake channel 0132 and the second input chamber 312. This allows the pressurized softener to enter the second input chamber 312 via the second intake channel 0132.

[0232] An opening is provided in the bottom wall of the first input chamber 311, and a siphon section 32 is provided at the opening. This allows the detergent and water that enter the first input chamber 311 to mix, and when the liquid level exceeds the working liquid level of the siphon section 32, the mixed detergent solution is discharged from the first input chamber 311. The opening in the bottom wall of the first input chamber 311 communicates with the water outlet section 15 provided at the bottom of the water storage tank 11 of the water case 1 below, and a water outlet 14 is provided at the lowest position of the bottom wall of the water outlet section 15. This allows the detergent solution to flow out through the water outlet 14 of the water case 1 via the water outlet section 15 of the water storage tank 11 and into the washing drum of the washing machine. An opening is provided in the bottom wall of the second input chamber 312, and a siphon section 32 is provided at the opening. As a result, the fabric softener and water that enter the second input chamber 312 mix, and when the liquid level exceeds the working liquid level of the siphon section 32, the mixed fabric softener liquid is discharged all at once from the second input chamber 312. An opening in the bottom wall of the second input chamber 312 communicates with the water outlet 15 located at the bottom of the water storage tank 11 of the water case 1 below, and a water outlet 14 is provided at the lowest position of the bottom wall of the water outlet 15. As a result, the fabric softener liquid is discharged to the outside from the water outlet 14 of the water case 1 via the water outlet 15 of the water storage tank 11 and put into the washing drum of the washing machine.

[0233] In the embodiments of the present invention, a washing machine will be further introduced. The washing machine may be any conventional garment processing equipment capable of processing clothes. These may include, for example, a drum-type washing machine, a swirl-type washing machine, a washer-dryer, or a dryer. In the embodiments of the present invention, for the sake of explanation, the discussion will be developed using the example of a swirl-type washing machine, but the present invention is not limited to a swirl-type washing machine. As shown in Figure 21, in the embodiments of the present invention, the top of the casing of the washing machine described above is a control panel base 200, and a washing tub is provided inside the casing with an axis extending vertically and a tub opening at the top. The control panel base 200 is located above the tub opening of the washing tub, and the detergent dispensing device 100 described above is mounted on the control panel base 200. The outlet 14 of the water case 1 of the detergent dispensing device 100 is drilled toward the tub opening of the washing tub, thereby allowing the water intake flow of the washing machine, the added laundry additives, etc., to be dispensed into the washing drum via the outlet 14 of the dispensing device.

[0234] In embodiments of the present invention, the control method for the washing machine described above includes the following:

[0235] The laundry additive dispenser acquires the pre-set amount to be dispensed and the amount of laundry additive in the manual dispenser module.

[0236] Formula: Differential input amount = Pre-set input amount - The differential input amount is obtained according to the amount of additive in the manual input module.

[0237] The automatic dispensing module is activated, drawing the difference in the amount of laundry additive from the storage chamber into the manual dispensing module.

[0238] Water is drawn into the water case, mixed with the laundry additive in the manual dispensing module, and then dispensed externally.

[0239] The aforementioned configuration allows for the automatic dispensing module to automatically replenish and dispense laundry additives that have been manually added by the user, significantly improving the accuracy of additive dispensing. Furthermore, by using two different dispensing modules, it is possible to synchronize and accurately dispense laundry additives into the washing machine in a coordinated manner, diversifying the functionality of the dispensing device and significantly improving the product's performance.

[0240] In embodiments of the present invention, the control method for the detergent dispensing device further includes the following:

[0241] Determine whether the amount of laundry additive in the manual dispensing module is greater than the preset dispensing amount.

[0242] If the amount is large, the automatic dispensing module will stop operating, draw water directly into the water case, mix it with the laundry additive in the manual dispensing module, and dispense it externally.

[0243] If the amount is small, the automatic dispensing module will start operating, and the difference in the amount of laundry additive will flow into the manual dispensing module, and then the laundry additive in the manual dispensing module will be dispensed externally by drawing water into the water case.

[0244] This prevents situations where the manual dispensing module contains an excessive amount of laundry additive, yet still draws it up from the storage case and dispenses it. This significantly improves the accuracy of laundry additive dispensing, effectively preventing the accidental addition of too much additive, which can lead to wasted additive and reduced washing effectiveness.

[0245] In embodiments of the present invention, the control method for the detergent dispensing device further includes the following:

[0246] The laundry additive dispenser determines the type of laundry additive to be added.

[0247] The amount of laundry additive in the dispenser corresponding to the determined type of laundry additive is detected.

[0248] Formula: Differential input amount = Pre-set input amount - The differential input amount is obtained according to the amount of additive in the manual input module.

[0249] The system controls and operates pumps that are connected to the storage chambers corresponding to the determined type of laundry additive. The determined type of laundry additive in the corresponding storage chamber is then sucked and transported via the pumps to the corresponding intake channel until the amount of laundry additive sucked up reaches the differential input amount.

[0250] Subsequently, water is drawn into the corresponding intake channel, and the intake water flow and laundry additive are introduced into the corresponding input chamber and mixed to form a laundry additive mixture, which is then poured into the washing drum of the washing machine through the outlet of the water case.

[0251] In an embodiment of the present invention, the explanation will be based on an example in which the dispensing device 100 has two sets of automatic dispensing modules and two sets of manual dispensing modules, and the first automatic dispensing module 111 and the first manual dispensing module 112 work together to dispense detergent, and the second automatic dispensing module 121 and the second manual dispensing module 122 work together to dispense fabric softener.

[0252] The specific operating modes of the dispensing device when dispensing detergent are as follows:

[0253] In step S111, the liquid level in the first input chamber is detected, and it is determined whether the detected value is smaller than the preset input amount. If it is smaller, step S112 is performed. If it is not smaller, step S114 is performed.

[0254] Step S112, Formula: Differential input amount = Pre-set input amount - Obtain the differential input amount according to the detected value.

[0255] In step S113, the first pump is activated to draw the detergent contained in the first storage chamber into the first intake channel. Once the amount of detergent drawn up reaches the differential input amount, step S114 is performed.

[0256] Step 114: Stop the first pump. The intake valve opens the inlet and the first outlet into fluid communication. The intake water flow in the first intake pipe flows into the first intake channel, collecting the drawn-up detergent and flushing it into the first input chamber.

[0257] Step S115: The intake water stream and detergent are mixed in the first input chamber to form a detergent mixture.

[0258] In step S116, water intake continues until the liquid level in the first input chamber exceeds the working liquid level of the siphon section. The detergent mixture in the first input chamber flows out to the outlet section below the water storage tank and is injected into the washing drum of the washing machine through the outlet located above the outlet section. This achieves the effect of both adding detergent and taking water into the washing machine.

[0259] The specific operating modes of the dispenser when dispensing fabric softener are as follows:

[0260] In step S211, the liquid level in the second input chamber is detected, and it is determined whether the detected value is less than the preset input amount. If it is less, step S212 is performed. If it is not less than the preset amount, step S214 is performed.

[0261] Step S212, Formula: Differential input amount = Pre-set input amount - Detected value. Obtain the differential input amount according to this formula.

[0262] In step S213, the second pump is activated to draw the fabric softener contained in the second storage chamber into the second intake channel. Once the amount of fabric softener drawn up reaches the differential input amount, step S214 is performed.

[0263] Step 214: Stop the second pump. The intake valve opens the inlet and the second outlet into fluid communication. The intake water flow in the second intake pipe flows into the second intake channel, collecting the fabric softener and sending it into the second input chamber.

[0264] Step S215: The intake water stream and detergent are mixed in the second input chamber to form a fabric softener mixture.

[0265] In step S216, water intake continues until the liquid level in the second input chamber exceeds the working liquid level of the siphon section. The fabric softener mixture in the second input chamber flows out to the outlet section below the water tank and is injected into the washing drum of the washing machine through the outlet located above the outlet section. This achieves the effect of both adding fabric softener and taking out water from the washing machine.

[0266] As shown in Figures 12 to 21, embodiments of the present invention further describe a detergent dispenser that is mounted on a washing machine. The aforementioned detergent dispenser 100 comprises a water case 1 and a detergent case 2 mounted inside the water case 1. The aforementioned detergent case 2 can be removed and opened by pulling it out by hand, and closed by pushing it inward. A liquid storage chamber 21 for storing detergent and laundry additives such as fabric softener is provided on the detergent case 2. The aforementioned liquid storage chamber 21 is composed of an independent chamber and may be detachably mounted on the detergent case 2, or it may be integrally installed on the detergent case 2 and be a liquid storage tank for storing laundry additives. An automatic dispensing module 101 is further provided on the water case 1 and is used to draw up the laundry additives in the liquid storage chamber 21 into the water storage tank 11 of the water case 1. A water intake pipe 6 is further connected to the water case 1, and the water intake pipe 6 draws water into the water storage tank 11 and mixes it with the water flow to form a laundry additive mixture. An outlet 14 is provided at the bottom of the water storage tank 11, allowing the laundry additive mixture and the intake water flow to flow out of the water case 1 through the outlet 14 and enter the washing tub of the washing machine.

[0267] In embodiments of the present invention, the automatic feeding module 101 described above may have any of the conventional structures. In embodiments of the present invention, the automatic feeding module 101 is configured as follows, but the scope of protection of the present invention is not limited to the following configuration.

[0268] A water intake channel 13 is integrally provided on the water case 1, and the inlet end of the water intake channel 13 is connected to the water intake pipe 6, and is used to introduce the water intake flow from the washing machine to the dispensing device. The automatic dispensing module 101 is equipped with a pump 21, and the liquid storage chamber 21 is in communication with the water intake channel 13 via a pump 04. As a result, the laundry additive contained in the liquid storage chamber 21 is automatically pumped into the water intake channel 13, mixed with the water intake flow, and can form a laundry additive mixture.

[0269] In an embodiment of the present invention, a water intake is provided on the water case 1. The water intake constitutes the water intake end of a water intake channel 13 that is integrally installed on the water case 1. The water intake is connected to the outlet of a water intake valve 5 via a water intake pipe 6, and the inlet of the water intake valve 5 communicates with the water source for the washing machine. The water source for the washing machine is generally the tap water in the user's home. The water intake valve 5 can control the opening and closing of the inlet of the water intake pipe 6 and is used to control the opening and closing of the supply of tap water to the water case 1.

[0270] In the daily lives of washing machine users, a lot of wastewater can be generated. For example, some of this wastewater, such as rice rinsing water, vegetable washing water, and floor cleaning water, can be reused in washing machines. This wastewater is generally referred to as "secondary supply water" and can be reused for washing, rinsing, and other processes in washing machines. To enable the use of secondary supply water in washing machines, users typically collect the secondary supply water in a water collection container and then pump it into the washing machine's water intake line via a pipeline equipped with a suction pump, thereby reusing the secondary supply water in the washing machine.

[0271] As shown in Figures 12 to 21, in the embodiment of the present invention, a water intake pump 7 is additionally installed on the washing machine, and the water intake pump 7 is mounted on the water supply device 100. The water intake pump 7 is connected in series to the water intake pipe 6 of the water supply device 100. As a result, the water intake pump 7 can draw in the secondary supply water it suctions and delivers directly into the washing drum of the washing machine via the water supply device 100, thereby achieving the effect of effectively utilizing the secondary supply water.

[0272] By connecting the suction pump in series to the intake pipe of the supply device, the supply device can controllly supply secondary supply water via the suction pump, while the intake pipe supplies tap water for intake. This achieves a remarkable technological advancement by integrating two different water supply modes into the supply device. Furthermore, the tap water supplied from the intake pipe can be effectively used to fill the pump chamber of the suction pump, thereby achieving a remarkable technological advancement by automatically controlling the suction pump to meet its operating requirements.

[0273] As shown in Figures 12 to 21, an embodiment of the present invention introduces a washing machine dispensing device 100 in which an externally connected suction pump is integrated. The washing machine dispensing device 100 consists of a water case 1 equipped with a water storage tank 11 for drawing water into the washing tub of a washing machine, a liquid storage chamber 21 installed inside the water case 1 for storing a garment treatment agent, and a pump 04 mounted on the water case 1. The pump 04 has an inlet connected to the liquid storage chamber 21, and an outlet connected to the water storage tank 11 via a water intake channel 13 provided on the water case 1. The garment treatment agent in the liquid storage chamber 21 is drawn into the water intake channel 13, which is integrally installed on the water case 1, and then enters the water storage tank 11 together with the water flow that has entered the water intake channel 13. After mixing in the water storage tank 11 to form a laundry additive mixture, the mixture is then dispensed through the outlet 14 of the water case 1. The device comprises a pump 04 that enters the washing tub of the washing machine, thereby realizing the function of adding laundry additives or drawing water into the washing machine; an intake pipe 6 whose outlet is connected to an intake water channel 13 and whose intake is connected to an intake valve 5, and whose intake valve 5 is connected to the washing machine's tap water tap in a controllable opening / closing manner; and a suction pump 7 connected in series on the intake pipe 6, which is further provided with a secondary supply water inlet 73 that is fluidly connected to an externally connected secondary supply water source in an openable / closable manner, and is used to introduce an intake water flow consisting of tap water supplied from the intake valve 5 for the washing machine or secondary supply water supplied from the suction pump 7 into the storage tank 11.Therefore, the adding device can use tap water or secondary supply water to wash away and add the laundry additives that have been introduced into the intake water channel, thereby achieving the effect of introducing laundry additives to the outside by adopting different water intake modes.

[0274] In an embodiment of the present invention, the suction pump 7 is provided with an inlet 71 and an outlet 72 connected in series with the intake pipe 6, and both the inlet 71 and the outlet 72 communicate with each other at the highest point of the pump chamber 74 of the suction pump 7. This ensures that the intake water can flow into the intake channel 13 of the supply device 100 only when the pump chamber 74 of the suction pump 7 is filled. The secondary supply water inlet 73 is located at the top of the pump chamber 74 of the suction pump 7 and is drilled upwards. The secondary supply water inlet 73 communicates with the secondary supply water source via a pipeline equipped with a check valve. The check valve is used to ensure that the water flow in the pipeline flows only in the direction of the secondary supply water inlet 73. Preferably, in order to ensure the direction of water flow within the intake pipe 6, a check valve is provided on the intake pipe 6 upstream of the suction pump 7. This is used to control the secondary supply water that flows into the pump chamber 74 so that it flows out only from the outlet 72 of the suction pump 7, and to prevent backflow in the direction of the intake valve 5.

[0275] In this embodiment of the present invention, the suction pump 7 is mounted above the water case 1 and located on one side of the water case 1. This ensures that water in the intake channel 13 of the input device 100 cannot flow back into the pump chamber 74 of the suction pump 7. Both the intake valve 5 and the suction pump 7 are mounted above the water case 1 and located on opposite left and right sides of the water case 1, respectively. This achieves the objective of preventing water in the intake channel 13 of the input device 100 from flowing back towards the intake valve 5. Preferably, to further avoid the occurrence of backflow of water within the input device, the inlet 71 and outlet 72 of the suction pump 7 and the outlet of the intake valve 5 are all located above the top wall of the water case 1.

[0276] In an embodiment of the present invention, the aforementioned water intake pipe 6 is configured as follows. Specifically, a first hose 63 is connected to the outlet of the water intake valve 5, and a second hose 64 and a third hose 65 are connected to the inlet 71 and outlet 72 of the water intake pump 7, respectively. The end of the first hose 63 is connected to the end of the second hose 64 via a connecting joint 66 to establish fluid communication, and the end of the third hose 65 is connected to the water intake channel 13, which is integrally installed on the water case 1, via a water intake joint installed on the water case 1 to establish fluid communication.

[0278] As shown in Figures 12 to 21, in the embodiment of the present invention, a fluid communication structure is provided between the water case 1 and the detergent case 2, and is used to enable fluid communication between the liquid storage chamber 21 and the water intake channel 13 so as to be able to open and close. Any of the prior art structures may be used for the aforementioned fluid communication structure. Specifically, the fluid communication structure in the embodiment of the present invention is as follows: A first liquid conduit 016 is provided on the liquid storage chamber 21, the liquid inlet end of the first liquid conduit 016 is inserted into the bottom of the liquid storage chamber 21, and the liquid outlet end is drilled toward the side in which the liquid storage chamber 21 is pushed into the water case 1. The liquid inlet end of the first liquid conduit 016 is higher than the highest liquid level of the liquid storage chamber 21, and the liquid outlet end of the first liquid conduit 016 is lower than the lowest liquid level of the liquid storage chamber 21. The water case 1 is provided with a second liquid conduit 017, the liquid outlet end of the second liquid conduit 017 communicating with the intake water channel 13 provided on the upper cover 12 of the water case 1. The liquid inlet end is provided on the rear side wall of the water case 1, facing inward, and is installed to be inserted coaxially with the liquid outlet end of the first liquid conduit 016 to enable fluid communication. After the detergent case 2 is pushed into the water case 1, the liquid outlet end of the first liquid conduit 016 is inserted with the liquid inlet end of the second liquid conduit 017 to enable fluid communication, thereby enabling the first liquid conduit 016 and the second liquid conduit 017 to communicate with each other.

[0279] As shown in Figure 20, in an embodiment of the present invention, the first liquid conduit 016 comprises a vertical portion extending vertically and a horizontal portion extending horizontally. The lower end of the vertical portion is located at the bottom of the liquid storage chamber and below the lowest liquid level in the liquid storage chamber 21, while the upper end is located above the highest liquid level in the liquid storage chamber 21. The front end of the horizontal portion is connected to the upper end of the vertical portion, and the rear end of the horizontal portion extends out of the liquid storage chamber 21 to form the liquid outlet end of the first liquid conduit 016. Preferably, the first liquid conduit 016 is installed integrally with the upper part of the detergent case 2. The second liquid conduit 017 also comprises a vertical portion extending vertically and a horizontal portion extending horizontally. The upper end of the vertical portion communicates with the water intake channel 13, which is integrally installed on the upper cover 12 of the water case 1, and the lower end is installed coaxially at the same height as the liquid outlet end of the first liquid conduit 016. The rear end of the horizontal section is connected to the lower end of the vertical section, and the front end of the horizontal section is inserted into the water case 1 and protrudes inward from the rear side wall of the water case 1, forming the liquid inlet end of the second liquid conduit 017, and is inserted coaxially opposite the liquid outlet end of the first liquid conduit 016.

[0280] In an embodiment of the present invention, the liquid outlet end of the first fluid conduit 016 is inserted correspondingly into the liquid inlet end of the second fluid conduit 017. The outer wall of the first fluid conduit 016 is in contact with the inner wall of the second fluid conduit 017, and a sealing ring is provided around it at least once. This creates a seal between the two fluid conduits after insertion, preventing the additive from leaking through the gap between them. Furthermore, to ensure that detergent does not leak from the first fluid conduit 016 or the second fluid conduit 017 after the detergent case 2 is pulled out, a switching valve may be provided at the liquid outlet end of the first fluid conduit 016 and / or the liquid inlet end of the second fluid conduit 017. The switching valve is used to close the corresponding end of the fluid conduit after the detergent case 2 is pulled out and to create fluid communication between the two inserted fluid conduits after the detergent case 2 is pushed in.

[0281] In an embodiment of the present invention, the water intake valve 5 has one inlet 051 and a plurality of outlets. The valve core of the water intake valve 5 is used to control the inlet 051 to communicate with each outlet alternatively. The inlet of the water intake valve 5 communicates with the tap water source through a pipeline. On the water case 1, a plurality of water intake channels 13 corresponding one-to-one to each outlet of the water intake valve 5 are provided. Each outlet of the water intake valve 5 communicates with the corresponding water intake channel 13 one-to-one through a different water intake pipe 6. The suction pump 7 is connected in series on one of the water intake pipes 6.

[0282] In an embodiment of the present invention, a detergent case 2 that can be pulled out is installed in the water case 1. A plurality of liquid storage chambers 21 are installed on the detergent case 2, and each liquid storage chamber 21 is for storing different types of clothing additives. Each liquid storage chamber 21 is in fluid communication with the corresponding water intake channel 13 one-to-one through a different pump 04. Here, detergent is stored in the first liquid storage chamber 211, and the first liquid storage chamber 211 communicates with the first water intake channel 0131 through the first pump 041. The first outlet 052 of the water intake valve 5 communicates with the first water intake channel 0131 downstream of the first pump 041 through the first water intake pipe 61, and the suction pump 7 is connected in series on the first water intake pipe 61. Thereby, the suction pump 7 is connected in series on the detergent input water path, and when the input device allows the washing water to enter the washing drum, the secondary supply water can be used as the water supply source. As a result, the washing machine can enter the washing additive into the washing drum together with the washing water intake to perform washing. Also, in subsequent stages such as rinsing, the water intake valve can be switched to other states, and tap water can enter the washing drum using other water intake pipes to rinse the clothes.

[0283] In an embodiment of the present invention, an additional input chamber 31 is provided on the input device to improve the uniformity of the mixing of the drawn-up laundry additive and the intake water. As a result, the outlet of the intake water channel 13 communicates with the input chamber 31, allowing the laundry additive and the intake water flow to flow into the input chamber 31 and mix thoroughly before flowing to the outlet section 15 of the water storage tank 11 and out through the outlet 14. This significantly improves the uniformity of the mixing of the laundry additive. In an embodiment of the present invention, an input case 3 that can be pulled out is installed inside the water case 1. The input case 3 has at least one input chamber 31. The top of the input chamber 31 is open, and an opening is provided at the bottom. The aforementioned opening directly constitutes the outlet 14 of the water case 1. Alternatively, the aforementioned opening is connected to the outlet 15 installed via the bottom of the water case 1 and communicates with the outlet 14 of the water case 1. A siphon section 32 is provided at the bottom opening of the input chamber 31. This siphon section 32 prevents unmixed additives from flowing out and is used to drain the mixed additive solution after mixing, thereby improving the uniformity of the mixing between the drawn-up laundry additives and the intake water flow. The aforementioned siphon section 32 may be any of the conventional siphon structures that can automatically activate the siphon drainage effect when the intake water level reaches a certain height. For example, the specific structure of the siphon section 32 is as follows: As shown in Figure 21, an inner sleeve pipe is provided extending vertically upward at the opening, and an outer sleeve pipe is coaxially fitted to the outside of the inner sleeve pipe. The top end of the outer sleeve pipe is closed, and the lower end has a gap between it and the bottom wall of the input chamber 31. The lower end of the inner sleeve pipe communicates with the water outlet section 15 below the input case 3, and there is a distance between the upper end and the closed top end of the outer sleeve pipe, thereby connecting the gap between the inner sleeve pipe and the outer sleeve pipe. The gap between the inner sleeve pipe and the outer sleeve pipe, as described above, constitutes a siphon flow path through which the input chamber and the outlet section communicate with each other. By utilizing the siphon section 32 with the above structure, a siphon effect is generated when the liquid level in the input chamber 31 is higher than the height of the inner sleeve pipe, allowing the laundry additive mixture in the input chamber 31 to be injected to the outside.In addition, in order to ensure that the inner cylinder and the outer cylinder of the siphon part can be installed at an interval, a plurality of support ribs may be arranged in the gap between the inner sleeve pipe and the outer sleeve pipe. Each support rib does not cover any of the flowing water cross-sections of the siphon flow path. By having a part of the support rib abut against the inner wall of the outer sleeve pipe and a part abut against the outer wall of the inner sleeve pipe, the inner sleeve pipe and the outer sleeve pipe can be supported at an interval, enabling assembly.

[0284] In addition, a water outlet chamber is provided on the upper cover 12 in the upper region of the charging chamber 31. The water outlet chamber constitutes the water outlet end of the water intake channel 13. A plurality of outlets are arranged on the bottom wall of the water outlet chamber, whereby the water intake flow and the charged washing additive are uniformly injected and introduced into the charging chamber through each outlet.

[0285] In the embodiment of the present invention, the description will be developed using an example in which two charging systems for respectively charging detergent and fabric softener are provided on the charging device 100, with a water absorption pump connected in series on the detergent charging water path.

[0286] As shown in Figures 12 to 21, a detergent case 2 is installed inside the water case 1 of the dispensing device 100. Two liquid storage chambers 21 are installed inside the detergent case; the first liquid storage chamber 211 is used to store detergent, and the second liquid storage chamber 212 is used to store fabric softener. A first pump 041 and a second pump 042 are provided on the water case 1. The inlet 051 of the water intake valve 5 is in communication with the water source of the washing machine, the first outlet 052 is in communication with the first water intake channel 0131 installed on the water case via the first water intake pipe 61, and the second outlet 053 is in communication with the second water intake channel 0132 installed on the water case 1 via the second water intake pipe 62. A suction pump 7 is connected in series on the first water intake pipe 61. Furthermore, the first hose 63, connecting fitting 66, second hose 64, suction pump 7, and third hose 65 are connected at their ends in order to form the first intake pipe 61, and the second intake pipe 62 is directly made up of a single hose. An opening is provided in the center of the first intake channel 0131, and this opening communicates with the outlet of the first pump 041, and the inlet of the first pump 041 is in fluid communication with the first liquid storage chamber 211. An opening is provided in the center of the second intake channel 0132, and this opening communicates with the outlet of the second pump 042, and the inlet of the second pump 042 is in fluid communication with the second liquid storage chamber 212.

[0287] A first outlet chamber 01311 is provided at the outlet end of the first intake channel 0131, and a number of first outlets 01312 are drilled at the bottom of the first outlet chamber 01311. Each of the first outlets 01312 is located above the first input chamber 311 and is used to connect the outlet of the first intake channel 0131 and the first input chamber 311 to each other. This allows the pressurized detergent to enter the first input chamber 311 via the first intake channel 0131. A second outlet chamber 01321 is provided at the outlet end of the second intake channel 0132, and a number of second outlets 01322 are drilled at the bottom of the second outlet chamber 01321. Each of the second outlets 01322 is located above the second input chamber 312 and is used to connect the second outlets 01322 of the second intake channel 0132 and the second input chamber 312. This allows the pressurized softener to enter the second input chamber 312 via the second intake channel 0132.

[0288] An opening is provided in the bottom wall of the first input chamber 311, and a siphon section 32 is provided at the opening. This allows the detergent and water that enter the first input chamber 311 to mix, and when the liquid level exceeds the working liquid level of the siphon section 32, the mixed detergent solution is discharged from the first input chamber 311. The opening in the bottom wall of the first input chamber 311 communicates with the water outlet section 15 provided at the bottom of the water storage tank 11 of the water case 1 below, and a water outlet 14 is provided at the lowest position of the bottom wall of the water outlet section 15. This allows the detergent solution to flow out through the water outlet 14 of the water case 1 via the water outlet section 15 of the water storage tank 11 and into the washing drum of the washing machine. An opening is provided in the bottom wall of the second input chamber 312, and a siphon section 32 is provided at the opening. As a result, the fabric softener and water that enter the second input chamber 312 mix, and when the liquid level exceeds the working liquid level of the siphon section 32, the mixed fabric softener liquid is discharged all at once from the second input chamber 312. An opening in the bottom wall of the second input chamber 312 communicates with the water outlet 15 located at the bottom of the water storage tank 11 of the water case 1 below, and a water outlet 14 is provided at the lowest position of the bottom wall of the water outlet 15. As a result, the fabric softener liquid is discharged to the outside from the water outlet 14 of the water case 1 via the water outlet 15 of the water storage tank 11 and put into the washing drum of the washing machine.

[0289] In the embodiments of the present invention, a washing machine will be further introduced. The washing machine may be any conventional garment processing equipment capable of processing clothes. These may include, for example, a drum-type washing machine, a swirl-type washing machine, a washer-dryer, or a dryer. In the embodiments of the present invention, for the sake of explanation, the discussion will be developed using the example of a swirl-type washing machine, but the present invention is not limited to a swirl-type washing machine. As shown in Figure 21, in the embodiments of the present invention, the top of the casing of the washing machine described above is a control panel base 200, and a washing tub is provided inside the casing with an axis extending vertically and a tub opening at the top. The control panel base 200 is located above the tub opening of the washing tub, and the detergent dispensing device 100 described above is mounted on the control panel base 200. The outlet 14 of the water case 1 of the detergent dispensing device 100 is drilled toward the tub opening of the washing tub, thereby allowing the water intake flow of the washing machine, the added laundry additives, etc., to be dispensed into the washing drum via the outlet 14 of the dispensing device.

[0290] In embodiments of the present invention, the control method for the washing machine described above includes the following:

[0291] When the washing machine is drawing water normally, the intake valve is opened and the suction pump is stopped. The intake pipe introduces tap water flowing in from the intake valve into the storage tank, and the clothing additive placed in the storage tank is then flushed into the washing machine drum.

[0292] When the washing machine uses the secondary water supply to draw water, the intake valve is closed and the suction pump is started. The suction pump introduces the drawn-in secondary water supply into the water tank via the intake pipe, and the clothing additive placed in the water tank is then flushed into the washing machine drum.

[0293] In embodiments of the present invention, the control method for the washing machine further includes the following:

[0294] When a washing machine uses a secondary water supply to draw water, first, the intake valve is opened and the suction pump is stopped. The intake pipe then flows tap water through the suction pump to the water storage tank, continuing until the pump chamber of the suction pump is filled with tap water.

[0295] Next, the intake valve is closed and the suction pump is started. The suction pump draws secondary supply water into the pump room via the secondary supply water inlet, and then allows it to flow into the storage tank via the intake pipe and suction channel.

[0296] In embodiments of the present invention, the control method for the washing machine further includes the following:

[0297] When a washing machine uses secondary water supply to draw water, it first opens the intake valve and stops the suction pump, which is maintained for a set time t1. Then, it closes the intake valve and starts the suction pump. The suction pump in this invention can only start operating when water has been injected until the pump chamber is full. Furthermore, in this invention, the suction pump is directly connected in series to the intake pipe of the input device. When the input device normally draws in tap water, the tap water flows through the pump chamber of the suction pump, maintaining the pump chamber of the suction pump in a full state under normal conditions. As a result, the suction pump can start operating immediately after receiving a command, significantly saving the time required for water intake. Furthermore, to ensure that the water intake pump is operational before starting it, and to avoid situations where water is not injected until the pump chamber of the water intake pump is full, the control method of this invention, in particular at the timing of starting secondary water intake, first opens the intake valve, allowing tap water to flow through the intake pipe and into the washing drum of the washing machine via the water intake pump, and uses the flowing tap water to ensure that water is injected until the pump chamber of the water intake pump is full. This achieves the effect of automatically driving and starting the water intake pump.

[0298] In the embodiments of the present invention, the explanation will be based on an example in which two dispensing systems for dispensing detergent and fabric softener are provided on the dispensing device 100, with a suction pump connected in series on the detergent dispensing water channel.

[0299] The specific operating modes when the dispensing device uses tap water to dispense detergent are as follows:

[0300] Step S101: Open the water intake valve to fluidly connect the inlet and the first outlet. Tap water flows into the first water intake pipe through the water intake valve.

[0301] Step S102: Activate the first pump to draw the detergent contained in the first liquid storage chamber into the first water intake waterway.

[0302] Step S103: The water intake water flow in the first water intake pipe flows into the first water intake waterway, and the sucked-up detergent is collectively poured into the first input chamber.

[0303] Step S104: Mix the water intake water flow and the detergent in the first input chamber to form a detergent mixture.

[0304] Step S105: Continue water intake until the liquid level in the first input chamber exceeds the operating liquid level of the siphon part. The detergent mixture in the first input chamber flows out to the water outlet part below the water storage tank and is injected into the washing drum of the washing machine from the water outlet installed on the water outlet part. Thereby, the effect of performing detergent input and water intake for the washing machine is realized.

[0305] The specific operation mode when the input device uses secondary supply water to input detergent is as follows.

[0306] Step S201: Open the water intake valve to fluidly connect the inlet and the first outlet. Tap water flows into the first water intake pipe through the water intake valve.

[0307] Step S202: When the time that the water intake valve is open reaches the set time and tap water is injected until the pump chamber of the water suction pump is full, close the water intake valve, start the water suction pump, and suck the secondary supply water into the first water intake pipe.

[0308] Step S203: Activate the first pump to draw the detergent contained in the first liquid storage chamber into the first water intake waterway.

[0309] Step S204: The water intake water flow in the first water intake pipe flows into the first water intake waterway, and the sucked-up detergent is collectively poured into the first input chamber.

[0310] Step S205: The intake water stream and detergent are mixed in the first input chamber to form a detergent mixture.

[0311] In step S206, water intake continues until the liquid level in the first input chamber exceeds the working liquid level of the siphon section. The detergent mixture in the first input chamber flows out to the outlet section below the water storage tank and is injected into the washing drum of the washing machine through the outlet located above the outlet section. This achieves the effect of both adding detergent and taking water into the washing machine.

[0312] The specific operating modes when the dispensing device uses tap water to dispense fabric softener are as follows:

[0313] Step S301: The intake valve is opened, creating fluid communication between the inlet and the second outlet. Tap water flows into the second intake pipe through the intake valve.

[0314] In step S102, the second pump is activated, drawing the softener contained in the second liquid storage chamber into the second water intake channel.

[0315] In step S103, the water flow from the second intake pipe flows into the second intake channel, and the sucked-up fabric softener is poured into the second input chamber.

[0316] Step S104: The intake water stream and detergent are mixed in the second input chamber to form a fabric softener mixture.

[0317] In step S105, water intake continues until the liquid level in the second input chamber exceeds the working liquid level of the siphon section. The fabric softener mixture in the second input chamber flows out to the outlet section below the water tank and is injected into the washing drum of the washing machine through the outlet located above the outlet section. This achieves the effect of both adding fabric softener and taking out water from the washing machine.
