Description

Technical Field

[0001] The invention belongs to the field of clothing cleaning, and in particular relates to a feeding device and a control method for a washing machine. Background Art

[0002] With the continuous improvement of people's living standards, washing machines have become one of the essential household appliances for family life. The drum washing machines and fully automatic pulsator washing machines in the prior art are usually provided with a washing additive delivery device for delivering detergent into the washing tub of the washing machine; generally, under the action of the water flow of the washing machine, the washing additive manually or automatically drawn and added by the user in the washing additive delivery device is flushed into the washing tub of the washing machine to achieve the purpose of delivering and using the washing additive. The above-mentioned washing additive can be any one or a combination of existing additives that can improve the treatment effect of clothes, such as detergents, softeners, disinfectants, etc.

[0003] At the same time, due to the shortage of fresh water resources, many household users basically have the habit of saving water resources, so most household users have the habit of using relatively clean secondary water such as bath water, rice washing water, vegetable washing water, etc. to supply washing machines for washing clothes. In order to provide secondary water as washing water for washing machines, the secondary water to be used is generally collected in a container, and the container is connected to the washing drum of the washing machine through a pipeline provided with a water suction pump, so that the secondary water is sucked into the washing drum by the water suction pump for use in clothes processing.

[0004] However, the existing secondary water is generally pumped directly to the washing drum without passing through the washing machine water inlet water channel. This means that when the washing additive needs to be added, the washing machine water inlet water source, generally a tap, is separately used to feed water into the washing additive adding device, and the washing additive to be added is added into the washing drum using tap water. This is not only time-consuming and laborious, but also requires the user to perform corresponding operations, which takes up a lot of the user's time.

[0005] In view of this, the present invention is proposed. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a dosing device, so that the water for dosing additives can use tap water or externally sucked secondary water, thereby achieving the purpose of enriching the water inlet mode and automatically reusing the secondary water. At the same time, by making the water inlet pipe branch with a second water branch pipe, the water suction pump is automatically primed while the main water inlet pipe is filling the water box, thereby eliminating the need to set a separate water inlet valve for the water suction pump.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: a dispensing device, including a water box, provided with a water storage tank and an automatic dispensing water circuit for supplying water to the barrel of the washing machine; a main water inlet pipe, used to supply water to the water box; the water outlet end of the main water inlet pipe is divided into a first water branch pipe and a second water branch pipe, the water outlet end of the first water branch pipe is connected to the water storage tank and the automatic dispensing water circuit respectively; the water outlet end of the second water branch pipe is connected to the water storage tank and the automatic dispensing water circuit respectively, a water suction pump is connected in series on the second water branch pipe, and the water suction pump is also provided with a secondary water inlet connected to an external secondary water source.

[0008] Furthermore, it also includes a water supply waterway, the two ends of which are respectively connected to the water storage tank and the water inlet end of the automatic water supply waterway; the water outlet ends of the first water branch pipe and the second water branch pipe are respectively connected to the middle of the water supply waterway.

[0009] Furthermore, a buffer zone protruding radially outward is provided in the middle of the water supply channel, and the water outlet ends of the first water branch pipe and / or the second water branch pipe are connected to the buffer zone.

[0010] Furthermore, the first water branch pipe is connected to the buffer zone, and the second water branch pipe is connected to the portion between the buffer zone of the water supply waterway and the automatic delivery waterway.

[0011] Furthermore, the second water diversion pipe includes at least a second diversion section and a third diversion section, which are respectively connected to the inlet and outlet of the water suction pump, and the passing area of ​​the second diversion section is smaller than the passing area of ​​the third diversion section.

[0012] Furthermore, a second one-way valve for one-way conduction is provided on the second water distribution pipe upstream of the water suction pump.

[0013] Furthermore, the water box is provided with a bottom wall constituting the bottom, and the front side of the bottom wall is provided with a liquid outlet that connects the space above the bottom wall with the bucket, and the water outlet end of the automatic water supply path and the water outlet end of the siphon structure arranged in the water storage tank are respectively arranged above the bottom wall.

[0014] A control method for a washing machine, wherein the above-mentioned dispensing device is installed in the washing machine; when the washing machine is normally supplied with water, the water inlet valve is opened, the water suction pump is closed, and the main water inlet pipe introduces the tap water flowing into the water inlet valve into the water storage tank, and the additives dispensed in the water storage tank or the automatic dispensing waterway are flushed into the barrel of the washing machine; when the washing machine is supplied with water using secondary water, the main water inlet valve is closed, the water suction pump is opened, and the water suction pump introduces the secondary water drawn in through the water inlet pipe into the water storage tank and the automatic dispensing waterway, and the clothing additives dispensed in the water storage tank or the automatic dispensing waterway are flushed into the barrel of the washing machine.

[0015] Furthermore, when the washing machine uses secondary water to fill, the water inlet valve is first opened and the water suction pump is closed. The main water inlet pipe allows tap water to flow through the water suction pump to the water storage tank until the pump chamber of the water suction pump is filled with tap water; then the water inlet valve is closed and the water suction pump is opened. The water suction pump draws secondary water into the pump chamber through the secondary water inlet, and then flows into the water storage tank and the automatic water supply circuit through the second water distribution pipe.

[0016] Furthermore, when the washing machine is supplied with secondary water, the water inlet valve is first opened and the water suction pump is closed for a set time t1, and then the water inlet valve is closed and the water suction pump is turned on.

[0017] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art: 1. By connecting the outlet of the water suction pump for sucking secondary water with the water storage tank and the automatic delivery pipeline, the delivery device can controllably supply secondary water through the water suction pump and tap water through the main water inlet pipe to rinse the detergent additive to be delivered in the delivery device, achieving a significant technical progress of integrating two different water supply modes in the delivery device;

[0018] 2. At the same time, the water suction pump is connected in series to the second water branch pipe of the delivery device. When the main water inlet pipe supplies water to the water box, the second water branch pipe automatically fills the water suction pump. The tap water supplied by the main water inlet pipe can be effectively used to fill the pump cavity of the water suction pump, thereby achieving a significant technical progress of automatically controlling the water suction pump to meet the opening requirements.

[0019] At the same time, the invention has a simple structure, significant effects and is suitable for popularization and use.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0029] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] It should be noted that in daily life, a lot of domestic wastewater may be generated, and some domestic wastewater can be used for secondary use by washing machines, such as rice washing water, the last rinse water in the last washing process, bath water, etc. The above domestic wastewater is generally referred to as secondary water, which can be used for secondary use by washing machines for washing and rinsing. In order to realize the use of secondary water by washing machines, users generally collect the above secondary water into a water container, and then suck it into the water inlet pipe of the washing machine through a pipe provided with a water suction pump 6, so as to realize the reuse of secondary water by the washing machine.

[0032] In the embodiment of the present invention, a secondary water storage chamber 7 is provided inside or outside the washing machine for storing collected secondary water as a secondary water source.

[0033] like Figure 1-4 As shown, in an embodiment of the present invention, a dispensing device is introduced, including a water box 1, provided with a water storage tank for supplying water to the barrel 8 of the washing machine and an automatic dispensing water circuit 11; a main water inlet pipe 21, used to supply water to the water box 1; the water outlet end of the main water inlet pipe 21 is divided into a first water branch pipe 22 and a second water branch pipe 23, the water outlet end of the first water branch pipe 22 is connected to the water storage tank and the automatic dispensing water circuit 11 respectively; the water outlet end of the second water branch pipe 23 is connected to the water storage tank and the automatic dispensing water circuit 11 respectively, and a water suction pump 6 is connected in series on the second water branch pipe 23, and the water suction pump 6 is also provided with a secondary water inlet 61 which is connected to an external secondary water source.

[0034] Through the above arrangement, by connecting the outlet of the water suction pump 6 for sucking secondary water with the water storage tank and the automatic delivery pipeline, the delivery device can controllably supply secondary water through the water suction pump 6 and tap water through the main water inlet pipe 21 to rinse the detergent additive to be delivered in the delivery device, thereby achieving the purpose of integrating two different water supply modes in the delivery device;

[0035] At the same time, the water suction pump 6 is connected in series to the second water branch pipe 23 of the delivery device. When the main water inlet pipe 21 supplies water to the water box 1, the second water branch pipe 23 automatically fills the water suction pump 6. The tap water supplied by the main water inlet pipe 21 can be effectively used to fill the pump cavity of the water suction pump 6, thereby achieving the purpose of automatically controlling the water suction pump 6 to meet the opening demand.

[0036] In an embodiment of the present invention, a siphon structure is provided in the water tank, which is connected to the barrel 8 through the siphon structure; before washing clothes, if the user selects the manual dosage mode, an appropriate amount of additives will be added to the water tank. During the water intake process, the water intake will flush all the additives in the water tank into the barrel 8 to realize manual dosage.

[0037] In an embodiment of the present invention, the delivery device further includes a liquid storage chamber, in which additives are stored; a delivery component 5, which connects the liquid storage chamber with the automatic delivery waterway 11, and is used to pump the additives in the liquid outlet chamber to the automatic delivery waterway 11; preferably, the delivery component 5 is a pump body; when in use, if the automatic delivery mode is selected, the delivery component 5 is controlled to extract an appropriate amount of additives and deliver it to the automatic delivery waterway 11, and the incoming water flushes the additives on the automatic delivery waterway 11 into the bucket 8 to achieve automatic delivery.

[0038] Through the above-mentioned arrangement, when the user chooses manual delivery, the user will add additives to the water tank by himself, and the delivery component 5 will not extract additives during the water intake process. Therefore, even if the incoming water passes into the automatic delivery waterway 11, the total amount of additives added will not increase; when the user chooses automatic delivery, the user will not add additives to the water tank, and the amount of additives delivered will not be greater than the preset value; at the same time, when the user prefers to use either automatic delivery or manual delivery, the pipeline corresponding to the other mode can also be flushed during the water intake process to prevent the pipeline from being unsmoothed or even blocked due to dust and impurities accumulating in the pipeline due to long-term non-use.

[0039] In one embodiment of the present invention, the water outlet ends of the first water branch pipe 22 and the second water branch pipe 23 are respectively divided into two small branches, one small branch of each first water branch pipe 22 is respectively connected to the water storage tank, and the other small branch is respectively connected to the automatic water supply circuit 11; thereby, the water outlet ends of each first water branch pipe 22 are respectively connected to the water storage tank and the automatic water supply circuit 11.

[0040] In another preferred embodiment of the present invention, it also includes a water supply circuit 12, the two ends of which are respectively connected to the water storage tank and the water inlet end of the automatic water supply circuit 11; the water outlet ends of the first water distribution pipe 22 and the second water distribution pipe 23 are respectively connected to the middle part of the water supply circuit 12.

[0041] Through the above arrangement, the outlet ends of the first water distribution pipes 22 are connected to the water storage tank and the automatic water supply circuit 11 respectively through a water supply circuit 12, thereby reducing the number of pipes in the water box 1 and reducing the complexity of the interior of the water box 1.

[0042] In an embodiment of the present invention, a buffer zone 123 protruding radially outward is provided in the middle of the water supply waterway 12, and the water outlet ends of the first water distribution pipe 22 and / or the second water distribution pipe 23 are connected to the buffer zone 123; preferably, the passing area of ​​the buffer zone 123 is larger than the passing area of ​​the water supply waterway 12.

[0043] Through the above arrangement, the incoming water first enters the buffer zone 123 for buffering to reduce the flow rate, and then enters the water supply pipe to be diverted to both ends, so that the direction of the water outlet end of the first water distribution pipe 22 and / or the second water distribution pipe 23 is biased towards the water storage tank or the end of the automatic water supply path 11, resulting in most of the incoming water flowing in the direction biased towards the water outlet end, thereby preventing the incoming water from being unable to flow according to the preset diversion ratio, thereby improving the stability of the water diversion and ensuring that the incoming water can be stably distributed on demand.

[0044] In the embodiment of the present invention, the first water distribution pipe 22 is connected to the buffer zone 123 , and the second water distribution pipe 23 is connected to the portion between the buffer zone 123 of the water supply waterway 12 and the automatic delivery waterway 11 .

[0045] During use, the automatic waterway 11 is usually provided with a plurality of bends so that the automatic waterway 11 can pass through the liquid outlet of the corresponding delivery component 5. However, when the water flow rate is relatively low, the undissolved additives will adhere to the side walls of the bends. By diverting the water from the main water inlet pipe 21 to the second water branch pipe 23 and converging the water flowing to the automatic waterway 11 on the water supply waterway 12, the flow rate of the water flowing in the automatic waterway 11 is increased, thereby avoiding the occurrence of the above-mentioned problem.

[0046] In an embodiment of the present invention, the first water diversion pipe 22 includes at least a second diversion section 222 and a third diversion section 223, which are respectively connected to the inlet and outlet of the water suction pump 6, and the passing area of ​​the second diversion section 222 is smaller than the passing area of ​​the third diversion section 223; by changing the passing area, the incoming water in the first water diversion pipe 22 flows to the third diversion section 223, and the flow rate of the incoming water is reduced, so that the incoming water flows out from the third diversion section 223 and when it merges with the water supply waterway 12, the impact on the water flow in the water supply waterway 12 is reduced, thereby preventing the generation of vortex in the water supply waterway 12, resulting in poor waterway flow.

[0047] In the embodiment of the present invention, the second guide section 222 and the third guide section 223 are hoses respectively; preferably, each hose is composed of a bendable and deformable rubber hose.

[0048] In the embodiment of the present invention, the first water diversion pipe 22 includes a first diversion section 221 , a second diversion section 222 and a third diversion section 223 which are connected in sequence, and the first diversion section 221 is connected to the main water inlet pipe 21 .

[0077] In an embodiment of the present invention, when the washing machine uses secondary water to fill the washing machine, the water inlet valve is first opened and the water suction pump is closed. The main water inlet pipe allows tap water to flow through the water suction pump to the water storage tank until the pump cavity of the water suction pump is filled with tap water. Then the water inlet valve is closed and the water suction pump is opened. The water suction pump draws secondary water into the pump cavity through the secondary water inlet, and then flows into the water storage tank and the automatic water supply circuit through the second water distribution pipe.

[0078] In the embodiment of the present invention, when the washing machine is filled with secondary water, the water inlet valve is first opened and the water suction pump is closed for a set time t1, and then the water inlet valve is closed and the water suction pump is opened.

[0079] Under normal circumstances, the water suction pump needs to be filled with water in the pump chamber before it can start working. Through the above-mentioned arrangement, the water suction pump is directly connected in series to the water inlet pipe of the delivery device, so that when the delivery device normally takes in tap water, the tap water will flow through the pump chamber of the water suction pump, so that the pump chamber of the water suction pump is kept in a full state under normal circumstances, so that the water suction pump can start working directly after receiving the instruction, which greatly saves the time spent on water intake; at the same time, before the water suction pump is started, in order to ensure that the water suction pump can be turned on and avoid the situation where the pump chamber of the water suction pump is not filled with water, the control method of the present application, especially at the start time node of secondary water inflow, first opens the water inlet valve, allows tap water to flow through the water suction pump through the water inlet pipe and into the washing drum of the washing machine, and uses the flowing tap water to ensure that the pump chamber of the water suction pump is filled, thereby achieving the effect of automatically driving the water suction pump to start working.

[0080] In the embodiment of the present invention, the dispensing device is provided with two channels for dispensing detergent and softener respectively, and the dispensing system in which a water suction pump is connected in series to the detergent dispensing water channel is taken as an example for further description:

[0086] Step S105, continue to fill water until the liquid level in the first delivery chamber exceeds the triggering liquid level of the siphon column, and the detergent mixture in the first delivery 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 provided on the water outlet part, so as to achieve the effect of adding detergent and filling water into the washing machine.

[0087] When the dispensing device uses secondary water to dispense detergent, the specific working mode is as follows:

[0088] Step S201, open the water inlet valve to connect the inlet with the first outlet, and the tap water flows into the first water inlet pipe through the water inlet valve;

[0089] Step S202: When the water inlet valve opening time reaches the set time and the pump cavity of the water suction pump is filled with tap water, the water inlet valve is closed and the water suction pump is opened to suck the secondary water into the first water inlet pipe;

[0090] Step S203: the first pump is turned on to pump the detergent contained in the first liquid storage chamber into the first water inlet channel;

[0091] Step S204: the water flow in the first water inlet pipe flows into the first water inlet channel, and the extracted detergent is flushed into the first delivery chamber;

[0092] Step S205: the incoming water flow and the detergent are mixed in the first delivery chamber to form a detergent mixed liquid;

[0093] Step S206, continue to fill water until the liquid level in the first delivery chamber exceeds the triggering liquid level of the siphon column, and the detergent mixture in the first delivery 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 provided on the water outlet part, so as to achieve the effect of detergent delivery and water filling into the washing machine.

[0094] In the embodiment of the present invention, when the dispensing device uses tap water to dispense softener, the specific working mode is as follows:

[0095] Step S301, open the water inlet valve to connect the inlet with the second outlet, and the tap water flows into the second water inlet pipe through the water inlet valve;

[0096] Step S102, the second pump is turned on to pump the softener contained in the second liquid storage chamber into the second water inlet waterway;

[0097] Step S103, the water flow in the second water inlet pipe flows into the second water inlet waterway, and the extracted softener is flushed into the second delivery chamber;

[0098] Step S104: the incoming water flow and the detergent are mixed in the second dispensing chamber to form a softener mixed liquid;
