Description

TECHNICAL FIELD

[0001] The present application belongs to the field of washing machines, and in particular relates to a washing machine control method. BACKGROUND

[0002] In order to accelerate the dissolution of washing powder, fully exert the efficacy of washing powder, and improve cleaning performance, hot water washing is being promoted. Users are used to dissolving washing powder in hot water before washing clothes, and then pouring the hot water into the inner barrel of the washing machine to start washing. The operation is complicated. Most of the current market heating washing is to install a heating pipe at the bottom of the barrel. After the water is filled to a certain level, the water is heated. The time for heating a barrel of water is long, the efficiency is low, and it is not safe.

[0003] A control method of a washing machine is disclosed in Chinese Patent No. 202010023199.5. The water mixed with the detergent is heated and circulated before the entire washing program starts, so that the detergent deposited in the washing barrel is fully circulated with the water. Hot water is added during the circulation process. Although the solubility of the detergent can be improved, the efficiency is reduced.

[0004] Therefore, the present application is proposed. SUMMARY

[0005] The technical problem to be solved by the present application is to overcome the shortcomings of the prior art, and to provide a washing machine and a control method thereof, which can dissolve and release the detergent by using heated water, and can realize water and electricity separation during heating, which is safe and efficient.

[0006] To solve the above technical problems, the basic idea of the technical solution of the present application is:

[0007] A washing machine comprises a water injection box, a water storage box, a water suction pump, an inner barrel and an outer barrel.

[0008] The water injection box is located in the disc seat above the inner barrel and the outer barrel, and is divided into a first water injection box and a second water injection box. The first water injection box is connected to a water inlet valve, and the first water injection box is provided with a water outlet to drain water to the outer barrel. The second water injection box is provided with a water outlet to drain water to the inner barrel, and the second water injection box is connected to the water storage box through a pipeline, and a water suction pump is arranged on the pipeline.

[0009] The outer barrel is provided with an outer barrel water outlet at the bottom, and the outer barrel water outlet is connected to the water storage box and a drain pipe through a three-way electromagnetic valve.

[0010] The water storage box is located at the bottom of the washing machine box body, and the inside of the water storage box is provided with a metal mesh, and the outside of the water storage box is provided with a mutual frequency heating module.

[0011] The water injection box is arranged above the inner tub and the outer tub of the washing machine and is divided into two independent chambers. The first water injection box is connected to the water inlet valve and can drain water to the outer tub. When water flows into the washing machine from the water inlet valve, it first flows into the first water injection box and then flows into the outer tub from the top of the outer tub. The bottom of the outer tub is provided with an outer tub drain and is connected to the water storage box through a three-way electromagnetic valve. Thus, water can be injected from the water inlet valve, the first water injection box and the outer tub to the water storage box. In order to realize the drainage from the first water injection box to the outer tub, an annular water receiving device is fixedly arranged at the top of the outer tub. The top of the water receiving device is open, and the bottom is provided with a plurality of drainage holes in communication with the outer tub. Since there is a gap between the inner tub and the outer tub, the drainage holes at the bottom of the water receiving device are made into inclined holes using the thickness of the bottom wall of the water receiving device. The inclined direction can be inclined downward along the radial direction of the outer tub towards the outer tub wall or in the form of inclined downward along the circumferential direction of the outer tub. Thus, the water entering the water receiving device can be flushed to the outer tub wall or into the gap between the outer tub and the outer tub along the circumferential direction of the outer tub without entering the inner tub.

[0012] The second water injection box is connected to the water storage box through a pipeline. A water suction pump is arranged on the pipeline. The second water injection box is provided with a drain to drain water to the inner tub. Thus, the water in the water storage box is pumped and transported through the pipeline by the water suction pump, and then drained into the second water injection box and the inner tub. When the detergent is poured into the second water injection box, the hot water in the water storage box can fully dissolve and flush the detergent into the inner tub of the washing machine, fully exert the effect of the detergent and improve the laundry cleaning ratio.

[0013] The water storage box is located at the bottom of the washing machine box. On the one hand, it can increase the weight at the bottom to stabilize the washing machine. On the other hand, it will not increase the structure of the upper part of the washing machine, so that the disc seat of the upper part of the washing machine still maintains a small size.

[0014] A metal mesh is arranged inside the water storage box, and a mutual frequency heating module is arranged outside the water storage box. The mutual frequency heating module installed outside the water storage box is used to inductively heat the metal mesh installed inside the water storage box, so that the metal mesh is inducted to increase the temperature, and then the water in the water storage box is heated. Since there is no contact between the mutual frequency heating module and the metal mesh, there is no current between them, thereby avoiding the electrification of the water flowing through the metal mesh.

[0015] Further, a temperature control probe is arranged in the water storage box.

[0016] A temperature control probe is installed in the water storage box to detect the water temperature. Since the solubility of the detergent is different at different temperatures, in order to make the detergent better dissolved to better exert its effect, the water in the water storage box needs to be heated to the most suitable temperature for the dissolution of the detergent, and the temperature control probe is used to detect whether the water temperature reaches the required temperature.

[0017] Further, the mutual frequency heating module is arranged below the water storage box.

[0018] The mutual frequency heating module is installed below the water storage box, and the metal mesh installed in the water storage box is inductively heated, so that the metal mesh is inductively heated to a high temperature, thereby heating the water flowing through the metal mesh. Since the mutual frequency heating module and the metal mesh are not in contact, there is no current between them, thereby avoiding the electrification of the water flowing through the metal mesh.

[0019] Further, the water storage box is provided with a water storage box drain at the bottom, and the water storage box drain is provided with a drain valve.

[0020] Since there may be some water remaining in the water storage box, and the water level is low to a certain extent, the water pump cannot be pumped, and if the remaining water remains in the water storage box for a long time, it may deteriorate and contaminate the clothes during washing. Therefore, a water storage box drain is provided at the bottom of the water storage box, and a drain valve is provided at the water storage box drain. In this way, when the water storage box does not need to drain the remaining water, the drain valve is closed, and when the water storage box needs to drain the remaining water, the drain valve of the water storage box drain is opened, thereby draining the remaining water.

[0021] Further, the water storage volume of the water storage box satisfies the water requirement for soaking clothes in the washing machine.

[0022] The water in the water storage box is used to fully dissolve the detergent after heating and soak the clothes, so the water storage volume of the water storage box satisfies the water requirement for soaking clothes in the washing machine. Since the inner barrel volume of a washing machine is limited, and the weight of the washing clothes is also limited, in order for the water storage volume of the water storage box to satisfy the water requirement for soaking clothes in the washing machine, the water storage volume of the water storage box is one fourth of the inner barrel volume.

[0023] The application also provides a washing machine control method, which is executed in the above washing machine, comprising the steps of:

[0024] S1: executing a user-set program, injecting a certain amount of water into the water storage box and heating to a preset temperature;

[0025] S2: draining the heated water in the water storage box into the second water injection box, dissolving the detergent in the second water injection box, and draining the water into the inner barrel until a first preset water level;

[0026] S3: starting to execute a pre-washing program until the pre-washing program ends;

[0027] S4: opening the water inlet valve until the water amount in the inner barrel of the washing machine reaches a second preset water level;

[0028] S5: executing a user-set program for washing.

[0029] Further, in step S1, the water inlet valve is opened to inject water into the first water injection box and then into the outer barrel, and at this time, the three-way electromagnetic valve connected to the outer barrel drain is opened to connect the water storage box, thereby realizing water injection into the water storage box.

[0030] After the water storage box is filled with water to the highest water level, the water inlet valve is closed and the three-way electromagnetic valve connected to the outer barrel drain outlet is closed to block the outer barrel drain outlet.

[0031] The mutual frequency heating module is started to heat the water in the water storage box to a preset temperature. The preset temperature is the most suitable temperature for the dissolution of the detergent. Since the solubility of the detergent is different at different temperatures, in order to make the detergent better dissolved to better play its effect, the water in the water storage box is heated to the most suitable temperature for the dissolution of the detergent.

[0032] Further, in step S2, the heated water in the water storage box is continuously discharged into the second water storage box by the water suction pump, the detergent in the second water storage box is fully dissolved, and the water is discharged into the inner barrel through the second water storage box until the water level in the inner barrel reaches the first preset water level capable of fully soaking the clothes, at which time the water suction pump is closed.

[0033] The water quantity of the first preset water level is the water quantity capable of fully wetting the clothes in the barrel of the washing machine. In order to make the clothes washed more thoroughly, it is necessary to use hot water and high-concentration detergent to fully soak the clothes, so the water is stopped from being added to the inner barrel of the washing machine after the water quantity capable of fully wetting the clothes in the barrel of the washing machine is reached.

[0034] Further, in step S4, the water inlet valve is opened to add water to the first water storage box and then to the outer barrel until the water quantity in the inner barrel of the washing machine reaches the second preset water level.

[0035] The water is stopped from being added when the water quantity in the inner barrel of the washing machine reaches the second preset water level. The water in the inner barrel reaches the second preset water level, which is the set water quantity for washing.

[0036] After the above technical solution is adopted, the present application has the following beneficial effects compared with the prior art.

[0037] The laundry washing machine comprises a water injection box, a water storage box, a water suction pump, an inner drum and an outer drum. The water injection box is located in a disc seat above the inner drum and the outer drum and is divided into a first water injection box and a second water injection box. The first water injection box is connected with a water inlet valve, and the first water injection box is provided with a water outlet for draining water into the outer drum. The second water injection box is provided with a water outlet for draining water into the inner drum, and the second water injection box is connected with the water storage box through a pipeline, and the water suction pump is arranged on the pipeline. The outer drum is provided with an outer drum water outlet at the bottom, and the outer drum water outlet is connected with the water storage box and a drain pipe through a three-way electromagnetic valve. The water storage box is located at the bottom of a washing machine box body, and the inside of the water storage box is provided with a metal mesh, and the outside of the water storage box is provided with a mutual frequency heating module. A laundry washing machine control method is also provided, which is executed on the above laundry washing machine and comprises the following steps: S1: executing a user-set program, injecting a certain amount of water into the water storage box and heating the water to a preset temperature; S2: draining the heated water in the water storage box into the second water injection box, dissolving the detergent in the second water injection box, and draining the water into the inner drum until a first preset water level; S3: starting to execute a pre-washing program until the pre-washing program ends; S4: opening the water inlet valve until the water amount in the inner drum of the laundry washing machine reaches a second preset water level; and S5: executing a user-set program for washing. By using the laundry washing machine and the control method thereof, the water is preheated by the water storage box during washing, the detergent is dissolved by using hot water first, and then the water is injected into the clothes in the drum, so that the laundry washing machine is better in the speed and effect of detergent dissolution, the clothes washing ratio is improved, the time for heating water is shortened, the overall washing efficiency is improved, water and electricity can be separated during heating, safety and high efficiency are achieved.

[0046] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0047] Combination Figure 1 , 2 As shown in the drawings, the present application is a washing machine, which comprises a water injection box, a water storage box 1, a water suction pump 2, an inner drum 5 and an outer drum 6.

[0048] The water injection box is located in the disc seat 3 above the inner drum 5 and the outer drum 6, and is divided into a first water injection box 41 and a second water injection box 42. The first water injection box 41 is connected to the water inlet valve 7, and the first water injection box 41 is provided with a water outlet to drain water to the outer drum 6; the second water injection box 42 is provided with a water outlet to drain water to the inner drum 5, and the second water injection box 42 is connected to the water storage box 1 through a pipeline, and the water suction pump 2 is arranged on the pipeline.

[0049] The outer drum 6 is provided with an outer drum 6 water outlet at the bottom, and the outer drum 6 water outlet is communicated with the water storage box 1 and the drain pipe 8 through a three-way electromagnetic valve 61, respectively.

[0050] The water storage box 1 is located at the bottom of the washing machine box, and the water storage box 1 is provided with a metal mesh 11 inside, and a mutual frequency heating module 13 outside.

[0051] The water injection box is arranged above the inner tub 5 and the outer tub 6, and is divided into two independent chambers. The first water injection box 41 is connected with the water inlet valve 7 and can drain water to the outer tub 6. When water flows from the water inlet valve 7 into the washing machine, the water first flows into the first water injection box 41, and then flows into the outer tub 6 from the top of the outer tub 6. The bottom of the outer tub 6 is provided with an outer tub 6 drain port and is connected with the water storage box 1 through a three-way electromagnetic valve 61. Thus, water can be injected from the water inlet valve 7, the first water injection box 41 and the outer tub 6 into the water storage box 1. In order to realize the drainage from the first water injection box 41 to the outer tub 6, an annular water receiving device can be fixedly arranged at the top of the outer tub 6. The top of the water receiving device is open, and the bottom of the water receiving device is provided with a plurality of drain holes in communication with the outer tub 6. Since there is a gap between the inner tub 5 and the outer tub 6, the drain holes at the bottom of the water receiving device are formed as inclined holes by using the thickness of the bottom wall of the water receiving device. The inclined direction of the inclined holes can be arranged in a form of being inclined downward along the radial direction of the outer tub 6 and toward the wall of the outer tub 6 or being inclined downward along the circumferential direction of the outer tub 6. Thus, the water entering the water receiving device can be flushed to the wall of the outer tub 6 or enter the gap between the outer tub 6 and the inner tub 5 along the circumferential direction of the outer tub 6, and the water will not enter the inner tub 5.

[0052] It can be understood that when the outer tub 6 drain port is connected with the water storage box 1 and the drain pipe 8 through the three-way electromagnetic valve 61, in order to facilitate connection, the three-way electromagnetic valve 61 is connected with the outer tub 6 drain port, the water storage box 1 and the drain pipe 8 through the connecting pipes.

[0053] The second water injection box 42 is connected with the water storage box 1 through a pipeline, and the water suction pump 2 is arranged on the pipeline. The second water injection box 42 is provided with a drain port for draining water to the inner tub 5. Thus, the water in the water storage box 1 is sucked and discharged into the second water injection box 42 through the pipeline by the water suction pump 2, and then is discharged into the inner tub 5. When the detergent is poured into the second water injection box 42, the hot water in the water storage box 1 can fully dissolve and flush the detergent, and then the detergent enters the inner tub 5 of the washing machine, so that the effect of the detergent is fully played and the clothes washing ratio is improved.

[0054] The water storage box 1 is arranged at the bottom of the washing machine box. On the one hand, the water storage box 1 can increase the weight at the bottom to stabilize the washing machine. On the other hand, the water storage box 1 will not increase the structure of the upper part of the washing machine, so that the disc seat 3 of the upper part of the washing machine still maintains a small size.

[0055] The water storage box 1 is internally provided with a metal mesh 11, and the water storage box 1 is externally provided with a mutual frequency heating module 13. The mutual frequency heating module 13 arranged outside the water storage box 1 is used for inductively heating the metal mesh 11 arranged inside the water storage box 1, so that the metal mesh 11 is inducted to increase the temperature, and then the water in the water storage box 1 is heated. Since there is no contact between the mutual frequency heating module 13 and the metal mesh 11, there is no current between the mutual frequency heating module 13 and the metal mesh 11, so that the water flowing through the metal mesh 11 is not electrified.

[0056] The water storage box 1 is provided with a temperature control probe 12.

[0057] A temperature control probe 12 is installed in the water storage box 1 to detect the water temperature, because the solubility of the detergent is different at different temperatures, in order to make the detergent better dissolved to better play its effect, so the water in the water storage box 1 needs to be heated to the most suitable temperature for the detergent to dissolve, and the temperature control probe 12 is used to detect whether the water temperature reaches the required temperature.

[0058] The mutual frequency heating module 13 is arranged below the water storage box 1.

[0059] The mutual frequency heating module 13 is arranged below the water storage box 1, and the metal mesh 11 installed in the water storage box 1 is inductively heated, so that the metal mesh 11 is inductively heated to a high temperature, thereby heating the water flowing through the metal mesh 11. Because the mutual frequency heating module 13 and the metal mesh 11 are not in contact, there is no current between them, thereby avoiding the water flowing through the metal mesh 11 from being electrified.

[0060] The bottom of the water storage box 1 is provided with a water storage box drain, and the water storage box drain is provided with a drain valve 14.

[0061] Because there may be some water remaining in the water storage box 1, and the water level is low to a certain extent, the water pump 2 cannot be pumped, and if the remaining water is stored in the water storage box 1 for a long time, it may deteriorate and cause pollution to the clothes during washing, therefore, the water storage box 1 needs to be provided with a water storage box drain at the bottom, and the water storage box drain is provided with a drain valve 14, so that when the water storage box 1 does not need to discharge the remaining water, the drain valve 14 is closed, and when the water storage box 1 needs to discharge the remaining water, the drain valve 14 of the water storage box drain is opened, thereby discharging the remaining water.

[0062] The water storage volume of the water storage box 1 meets the water requirement for soaking clothes in the washing machine.

[0063] The water in the water storage box 1 is used for heating, fully dissolving the detergent and soaking the clothes, so the water storage volume of the water storage box 1 meets the water requirement for soaking clothes in the washing machine. Because the volume of the inner tub 5 of a washing machine is limited, and the weight of the clothes to be washed is also limited, in order for the water storage volume of the water storage box 1 to meet the water requirement for soaking clothes in the washing machine, the water storage volume of the water storage box 1 is one fourth of the volume of the inner tub 5.

[0064] The application also provides a washing machine control method, which is executed in the above washing machine, comprising the steps of:

[0065] S1: executing a program set by a user, injecting a certain amount of water into the water storage box 1 and heating to a preset temperature;

[0066] S2: discharging the heated water in the water storage box 1 into the second water injection box 42, dissolving the detergent in the second water injection box 42, and discharging the water into the inner tub 5 until a first preset water level;

[0067] S3: start to execute the pre-washing program until the pre-washing program is finished;

[0068] S4: open the water inlet valve 7 until the water amount in the inner drum 5 of the washing machine reaches the second preset water level;

[0069] S5: execute the program set by the user for washing.

[0070] In step S1, the water inlet valve 7 is opened to fill water into the first water filling box 41 and then into the outer drum 6. At this time, the three-way electromagnetic valve 61 connected to the water outlet of the outer drum 6 is opened to connect the water storage box 1, so as to fill water into the water storage box 1.

[0071] After the water storage box 1 is filled with water to the highest water level, the water inlet valve 7 is closed and the three-way electromagnetic valve 61 connected to the water outlet of the outer drum 6 is closed to close the water outlet of the outer drum 6.

[0072] The mutual frequency heating module 13 is started to heat the water in the water storage box 1 to a preset temperature. The preset temperature is the most suitable temperature for dissolving the detergent. Since the solubility of the detergent is different at different temperatures, in order to make the detergent better dissolved to better play its effect, the water in the water storage box 1 is heated to the most suitable temperature for dissolving the detergent.

[0073] In step S2, the heated water in the water storage box 1 is continuously discharged into the second water filling box 42 by the water suction pump 2, the detergent in the second water filling box 42 is fully dissolved, and the water is discharged into the inner drum 5 through the second water filling box 42 until the water level in the inner drum 5 reaches the first preset water level capable of fully soaking the clothes, at which time the water suction pump 2 is closed.

[0074] The water amount of the first preset water level is the water amount capable of fully wetting the clothes in the drum of the washing machine. In order to make the clothes washed more thoroughly, the clothes need to be fully soaked by using hot water and high-concentration detergent, so the water filling is stopped after the water amount in the inner drum 5 of the washing machine reaches the water amount capable of fully wetting the clothes in the drum of the washing machine.

[0075] In step S4, the water inlet valve 7 is opened to fill water into the first water filling box 41 and then into the outer drum 6 until the water amount in the inner drum 5 of the washing machine reaches the second preset water level.

[0076] The water filling is stopped when the water amount in the inner drum 5 of the washing machine reaches the second preset water level. The water in the inner drum 5 reaches the second preset water level, which is the set water amount for washing.

[0077] The laundry washing machine comprises a water injection box, a water storage box, a water suction pump, an inner drum and an outer drum. The water injection box is located in a disc seat above the inner drum and the outer drum and is divided into a first water injection box and a second water injection box. The first water injection box is connected with a water inlet valve, and the first water injection box is provided with a water outlet for draining water to the outer drum. The second water injection box is provided with a water outlet for draining water to the inner drum, and the second water injection box is connected with the water storage box through a pipeline, and the water suction pump is arranged on the pipeline. The outer drum is provided with an outer drum water outlet at the bottom, and the outer drum water outlet is connected with the water storage box and a drain pipe through a three-way electromagnetic valve. The water storage box is located at the bottom of a washing machine box body, and a metal mesh is arranged inside the water storage box, and a mutual frequency heating module is arranged outside the water storage box. A laundry washing machine control method is also provided, which is executed on the above laundry washing machine and comprises the following steps: S1: executing a user-set program, injecting a certain amount of water into the water storage box and heating the water to a preset temperature; S2: draining the heated water in the water storage box into the second water injection box, dissolving the detergent in the second water injection box, and draining the water into the inner drum until a first preset water level; S3: starting to execute a pre-washing program until the pre-washing program ends; S4: opening the water inlet valve until the water amount in the inner drum of the laundry washing machine reaches a second preset water level; and S5: executing a user-set program for washing. By using the laundry washing machine and the control method thereof, the water is preheated by the water storage box during washing, the detergent is dissolved by using hot water first, and then the water is injected into the clothes in the drum, so that the laundry washing machine is better in terms of the dissolution speed and effect of the detergent, the clothes washing ratio is improved, the time for heating water is shortened, the overall washing efficiency is improved, water and electricity can be separated during heating, and safety and efficiency are high.
