Description

Technical Field

[0001] The present invention belongs to the technical field of washing equipment, and in particular, relates to a control method for washing equipment and the washing equipment. Background Art

[0002] Existing washing machines, especially drum washing machines, are almost all top-drain type. After washing, the drainage pump of the top-drain washing machine will leave about 300 to 600 ml of water. This water is difficult to be pumped away by the water pipe, and will slowly evaporate after washing, and return to the inner drum through the pipe, causing the inner drum to always be in a dark and humid environment, breeding bacteria and producing odor. Therefore, it is necessary to ensure that the drainage pump is completely dry after washing.

[0003] At present, the washing equipment with upper drainage has a typical siphon structure because the drainage pipe rises first and then falls after leaving the drainage pump and finally inserts into the floor drain. The water outlet is lower than the water inlet, which is a typical siphon structure. When adding clothes in the middle, if the water level exceeds the observation window, in order to prevent the washing water from flowing onto the ground, the drainage must be started. However, once the drainage is started, even if the drainage pump is stopped, the drainage cannot be stopped because a siphon has been formed. In this way, all the water must be drained before it can be stopped.

[0004] In summary, how to achieve complete drying of the drainage pump and, in the process, control the drainage pipe to stop siphoning is a technical problem that needs to be solved.

[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 control method and a washing device for a washing device. Heated water is introduced into a drainage device and unheated water is discharged. When / after the drainage device is heated to a high temperature state by water, the water is only drawn out by siphoning through a siphon pipe to ensure that there is less residual water in the drainage device. The heat released by the high temperature state of the drainage device is used to dry and evaporate the small amount of residual water in the drainage device, and the water is discharged by the drainage device, thereby achieving complete drying of the drainage device and avoiding moisture and mold between the inner and outer drums.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0008] The present invention provides a control method for a washing device, wherein the washing device comprises a heating chamber and a drainage device, wherein a water inlet end of the drainage device is connected to the heating chamber, a first water outlet end of the drainage device is connected to a drainage pipeline, and a second water outlet end of the drainage device is connected to a siphon pipeline; a cross-sectional area of ​​the siphon pipeline is smaller than a cross-sectional area of ​​the drainage pipeline;

[0009] The washing device performs a pump drying procedure, including:

[0010] After the washing equipment heats the water in the heating chamber to a set temperature, the drainage device is started to draw the heated water into the drainage device and drain the water outwards simultaneously along the drainage pipeline and the siphon pipeline;

[0011] After a first set time period, the drainage device is closed, and the water in the drainage device is controlled to stop entering the drainage pipeline;

[0012] During the second set time, the heated water is completely discharged by the siphon pipeline;

[0013] After the second set time period, the drainage device is turned on again.

[0014] The present invention introduces heated water into the drainage device and discharges unheated water. When / after the drainage device is heated to a high temperature state by water, the water is only drawn out by siphoning through a siphon pipe to ensure that there is less residual water in the drainage device. The heat released by the high temperature state of the drainage device is used to dry and evaporate the small amount of residual water in the drainage device. The evaporated water vapor is discharged by the drainage device, thereby achieving complete drying of the drainage device and avoiding moisture and mold inside and outside and between the cylinders.

[0015] A further solution of the present invention is that: the valve element connects the siphon pipeline and the drainage pipeline, and when the valve element is opened, the drainage pipeline and the siphon pipeline are simultaneously connected to the external atmosphere; the portion of the siphon pipeline close to its drainage outlet is inserted into the interior of the drainage pipeline, and the water outlet of the siphon pipeline is not longer than the opening of the drainage pipeline;

[0016] The pump drying procedure includes: after a first set time, continuously closing the drainage device and continuously controlling the valve member to open for a sixth set time;

[0017] continuously opening the drainage device again and controlling the valve member to close for a seventh set time period;

[0018] After the seventh set time, the drainage device is closed and the second set time is entered;

[0019] During the second set time period, the heated water is partially discharged by the siphon of the drainage pipeline and then completely discharged by the siphon pipeline.

[0020] In the above scheme, through the sixth set time, the heated water is retained in the drainage device for a certain period of time, so that the drainage device is fully heated by the water. Through the seventh set time, the heated water in the drainage device is discharged into the drainage pipe. A negative pressure environment is formed at the drain outlet of the siphon pipe when the water flows through the siphon pipe, so that the siphon pipe produces siphon, and the drainage pipe and the siphon pipe are discharged at the same time, thereby improving the drainage efficiency. The drainage device is closed after the seventh set time, so that when there is both water and air in the drainage device, the operation of the drainage device can be prevented from generating loud noise.

[0021] A further solution of the present invention is: the drainage device is connected to the heating chamber through a water inlet pipeline, and the first set time is not less than the time it takes for the water in the water inlet pipeline to be completely discharged through the drainage device;

[0022] The drainage pipeline is provided with a valve member for controlling the connection and disconnection between the drainage pipeline and the external atmosphere;

[0023] Controlling water in the drainage device to stop entering the drainage pipeline includes: controlling the valve member to open, connecting the drainage pipeline with the external atmosphere, and preventing the drainage pipeline from generating a siphon effect.

[0024] In the above scheme, by completely discharging the unheated water in the water inlet pipe from the drainage device and only extracting the heated water from the drainage device through siphoning of the siphon pipe during the first set time, a better heating effect of the heated water on the drainage device is further ensured.

[0025] A further solution of the present invention is that: the valve member is also connected to the siphon pipeline, and when the valve member is opened, the drainage pipeline and the siphon pipeline are simultaneously connected to the external atmosphere; the portion of the siphon pipeline close to its drainage outlet is inserted into the interior of the drainage pipeline, and the water outlet of the siphon pipeline is not longer than the opening of the drainage pipeline;

[0026] The pump drying program includes: the washing device sets a third set time length between the first set time length and the second set time length;

[0027] Controlling the valve member to remain open for the third set time, and then controlling the valve member to close, cutting off the connection between the siphon pipeline and the drainage pipeline and the external atmosphere, so that the siphon pipeline generates a siphon effect again;

[0028] When the valve member is kept in a closed state, the heated water is completely discharged along the siphon pipeline.

[0029] In the above scheme, it is ensured that after the siphoning of the drainage pipeline and the siphon pipeline is cut off, water flows through the drainage outlet of the siphon pipeline to form a negative pressure environment, so that the siphon pipeline regenerates siphoning and maintains siphoning for the second set time.

[0030] A further solution of the present invention is that: the heating chamber is connected to the outer drum of the washing equipment;

[0031] Before heating the water in the heating chamber, the washing device further comprises:

[0032] Starting the drainage device to discharge the water in the outer cylinder to the outside;

[0033] When it is detected that the water level in the heating chamber drops to a maximum set value, the drainage device is controlled to stop operating;

[0034] Start heating the water in the heating chamber.

[0035] In the above scheme, the water in the outer drum is used for heating, and the heated water is used to heat the drainage device for drying.

[0036] A further solution of the present invention is: after controlling the drainage device to stop running, the washing equipment continuously detects the water level in the heating cavity, and if the detected water level continues to be less than the maximum set value for a fourth set time period, the water in the heating cavity begins to be heated.

[0037] In the above scheme, it is ensured that in the process of heating the water in the heating chamber, the amount of water exceeding the maximum set value will not enter, and the water flow in the heating chamber is ensured not to touch the inner drum in operation, that is, the maximum amount of water is preserved for heating without affecting the dehydration work.

[0038] A further solution of the present invention is that the washing equipment controls the drainage device to stop operating and controls the valve member to be turned on.

[0039] In the above scheme, it is ensured that water will not be siphoned into the drainage pipe by the drainage pipe and the siphon pipe, thereby ensuring the effect of the heating chamber on heating the water.

[0040] A further solution of the present invention is that the washing device executes the pump drying program during the last dehydration process of the currently running washing program.

[0041] In the above scheme, the dehydrated water flow is used for heating, and the heated drainage is used to heat the drainage device for drying.

[0042] A further solution of the present invention is: if the washing device has received a pump drying instruction, the pump drying program is executed at the beginning of the last drainage of the last dehydration of the washing device.

[0043] In the above scheme, the user can control whether to dry and evaporate the residual water in the drainage device, thereby reducing the number of drying and evaporation times of the washing device, thereby reducing the energy consumption of the washing device.

[0044] The present invention also provides a washing device, and the washing device applies the control method of the washing device.

[0045] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0046] 1. Pass heated water into the drainage device and discharge unheated water. When the drainage device is heated to a high temperature by water, it is only siphoned out through the siphon pipe to ensure that there is less residual water in the drainage device. The heat released by the high temperature state of the drainage device is used to dry and evaporate the small amount of residual water in the drainage device. The evaporated water vapor is discharged by the drainage device to achieve complete drying of the drainage device and avoid moisture and mold inside and outside and between the cylinders.

[0047] 2. The unheated water is completely discharged from the drainage device within the first set time, and the water is only drawn out through the siphon of the siphon pipe without siphoning the drainage pipe within the second set time, so that the water is drawn out slower than through the drainage pipe, thereby ensuring that the heated drainage device passes the water to a high temperature state.

DETAILED DESCRIPTION

[0065] 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.

[0067] 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.

[0068] like Figures 1 to 7 As shown, the present invention provides a control method and a washing device for a washing device, wherein heated water is introduced into the drain device 220, and unheated water is discharged. When / after the drain device 220 is heated to a high temperature state by water, the water is only drawn out by siphoning through the siphon pipe 710 to ensure that there is less residual water in the drain device 220. Then, the heat released by the high temperature state of the drain device 220 is used to dry and evaporate the small amount of residual water in the drain device 220. The evaporated water vapor is discharged by the drain device 220, thereby achieving complete drying of the drain device 220 and avoiding moisture and mold outside the inner drum 160.

[0069] Embodiment 1

[0070] like Figures 1 to 5 As shown, this embodiment provides a control method for a washing device, wherein the washing device includes a heating chamber 800 and a drainage device 220, wherein a water inlet end of the drainage device 220 is in communication with the heating chamber 800, a first water outlet end of the drainage device 220 is connected to a drainage pipeline 320, and a second water outlet end of the drainage device 220 is connected to a siphon pipeline 710; a cross-sectional area of ​​the siphon pipeline 710 is smaller than a cross-sectional area of ​​the drainage pipeline 320;

[0071] The washing device executes a pump drying program, including: after the washing device heats the water in the heating chamber 800 to a set temperature, the drainage device 220 is started to pump the heated water into the drainage device 220 while draining the water outward along the drainage pipe 320 and the siphon pipe 710 at the same time; after a first set time, the drainage device 220 is closed, and the water in the drainage device 220 is controlled to stop entering the drainage pipe 320; in a second set time, the heated water is completely discharged by the siphon pipe 710; after the second set time, the drainage device 220 is opened again.

[0072] Heated water is introduced into the drainage device 220, and unheated water is discharged. When / after the drainage device 220 is heated to a high temperature state by water, it is only siphoned out by the siphon line 710 to ensure that there is less residual water in the drainage device 220. The heat released by the high temperature state of the drainage device 220 is used to dry and evaporate the small amount of residual water in the drainage device 220. The evaporated water vapor is discharged by the drainage device 220, thereby achieving complete drying of the drainage device 220 and avoiding moisture and mold in the inner cylinder 160 and the outer cylinder 130.

[0073] The second set time ensures that when the drainage device 220 is heated to a high temperature by heated water, the water is pumped out only by siphoning through the siphon pipe 710, which ensures that the water in the drainage device 220 will be basically drained and that the water has a good heating effect on the drainage device 220.

[0074] In this embodiment, the drainage device 220 is connected to the heating chamber 800 through the water inlet pipe 210, and the first set time is not less than the time for the water in the water inlet pipe 210 to be completely discharged through the drainage device 220; the drainage pipe 320 is provided with a valve component 730 for controlling the connection and disconnection between it and the external atmosphere; controlling the water in the drainage device 220 to stop entering the drainage pipe 320 includes: controlling the valve component 730 to open, connecting the drainage pipe 320 with the external atmosphere, so that the drainage pipe 320 does not produce a siphon effect, that is, the drainage device stops draining when it is closed.

[0075] Specifically, the time length for the water in the water inlet pipe 210 to be completely discharged through the drainage device 220 is the time length for the unheated water in the water inlet pipe 210 to be completely discharged from the drainage device 220. Therefore, after the drainage device 220 is closed, it is possible to avoid the mixing of the unheated water and the heated water, thereby reducing the heating effect of the drainage device 220.

[0076] By completely discharging the unheated water in the water inlet pipe 210 from the drainage device 220 and only siphoning the heated water of the drainage device 220 through the siphon pipe 710 during the first set time, a better heating effect of the heated water on the drainage device 220 is further ensured.

[0077] In this embodiment, the valve member 730 is also connected to the siphon pipeline 710. When the valve member 730 is opened, the drainage pipeline 320 and the siphon pipeline 710 are simultaneously connected to the external atmosphere; the portion of the siphon pipeline 710 close to its drainage port is inserted into the interior of the drainage pipeline 320, and the water outlet of the siphon pipeline 710 is not longer than the opening of the drainage pipeline 320;

[0078] The pump drying program includes: the washing device sets a third set time between the first set time and the second set time; the valve component 730 is controlled to be continuously open for the third set time, and then the valve component 730 is controlled to be closed, so as to cut off the connection between the siphon pipeline 710 and the drainage pipeline 320 and the external atmosphere, so that the siphon pipeline 710 regenerates the siphon effect; when the valve component 730 remains in the closed state, the heated water is completely discharged along the siphon pipeline 710.

[0079] It is ensured that after the siphon of the drainage pipe 320 and the siphon pipe 710 is cut off, water flows through the drainage outlet of the siphon pipe 710 to form a negative pressure environment, so that the siphon pipe 710 regenerates siphon and maintains siphon during the second set time.

[0080] In this embodiment, the washing device is preferably a top-drainage washing machine or a washer-dryer, and the drainage device 220 is preferably a drainage pump, and its drainage structure is arranged as follows: Figure 2 As shown, specifically, the heating chamber 800 is connected to the drainage device 220 through the water inlet pipe 210, the upper part of the drainage device 220 is connected to the drainage pipe 320, and the bottom is connected to the siphon pipe 710. The siphon pipe 710 is provided with a curved structure at the highest point in the vertical direction, and a siphon effect is generated through the curved structure, so that the water therein passes upward over the highest point and then pumps water downward, and the siphon pipe 710 is inserted into the drainage pipe 320 at least near its drainage port, forming a pipe-in-pipe structure with the drainage pipe 320, and the drainage port of the siphon pipe 710 is set to be no longer than the opening of the drainage pipe 320 outside it. Therefore, when the drainage device 220 is in operation, the drainage device 220 sends the pressurized water flow into the drainage pipe 320, so that the water flow in the drainage pipe 320 flows through the drainage port of the siphon pipe 710 to form a negative pressure environment, and then the water in the drainage device 220 is sucked into the siphon pipe 710. In detail, according to the Bernoulli principle of fluid mechanics, the water flow velocity at the water outlet is faster, which reduces the air pressure in the water outlet, thus forming a negative pressure environment at the water outlet, and making the pressure at the water inlet of the siphon pipeline 710 greater than the water outlet. In a specific application of this embodiment, the water outlet of the siphon pipeline 710 and the opening of the drainage pipeline 320 are inserted into a floor drain below the bottom of the housing of the washing device, so that the water inlets of the siphon pipeline 710 and the drainage pipeline 320 are both higher than their water outlets.

[0081] Further, such as Figure 2The drainage structure shown is also provided with a device for controlling whether the drainage pipeline 320 and the siphon pipeline 710 generate siphon, specifically: a connector 330 is provided on the drainage pipeline 320, and the connector 330 is connected to the multi-head channel 720 through a connecting pipeline 770. The multi-head channel 720 is also connected to the siphon pipeline 710, and a valve member 730 for controlling the conduction and blocking with the external atmosphere is provided on the multi-head channel 720. When the valve member 730 is turned on, the atmosphere passes through the multi-head channel 720 and enters the siphon pipeline 710 and the drainage pipeline 320, thereby changing the pressure inside the siphon pipeline 710 and the drainage pipeline 320, and cutting off the siphon of the siphon pipeline 710 and the drainage pipeline 320.

[0082] Furthermore, the shell of the drainage device 220 is preferably made of heat storage phase change material, so the shell can be heated to a high temperature state by heated high-temperature water, and the shell releases heat after the high-temperature water is drained, so that a small amount of residual water in the shell is evaporated by heat.

[0083] In this embodiment, Figure 3 As shown, the specific process of the drying process is as follows: controlling the drainage device 220 to continuously operate for a first set time, so that the cold water in the water inlet pipe 210 is sucked into the drainage device 220 and discharged from the washing device through the drainage pipe 320, while the water heated to the set temperature is sucked into the drainage device 220;

[0084] At the end of the first set time, the drainage device 220 is closed and the third set time is entered. The valve member 730 is controlled to remain conductive during the third set time and is blocked after the third set time. The third set time is set to a relatively small value of only a few seconds and is less than the time it takes for the water in the drainage pipeline 320 to be discharged from the highest point to the water outlet. When the valve member 730 is conductive, the siphon of the siphon pipeline 710 and the drainage pipeline 320 is cut off at the same time. When the valve member 730 is blocked, there is enough water flowing through the drainage outlet of the siphon pipeline 710, so that the siphon of the siphon pipeline 710 is regenerated.

[0085] After the third set time, the second set time is entered, and the control valve member 730 is kept blocked during the second set time, so that the siphon pipe 710 continuously and slowly extracts the water in the drainage device 220 by siphoning during the second set time, so that the water stays in the drainage device 220 for a time sufficient to heat the drainage device 220 to a high temperature state, and is slowly drained by the siphon pipe 710, so that only a small amount of residual water remains in the drainage device 220;

[0086] After the second set time, the fifth set time is entered, and the drainage device 220 is controlled to continuously operate during the fifth set time, so that the drainage device 220 releases the heat stored in its high temperature state, and a small amount of residual water in the drainage device 220 is evaporated by heat, and the drainage device 220 runs without water, discharges water vapor, and achieves complete drying of the drainage device 220, thereby preventing moisture and mold between the inner cylinder 160 and the outer cylinder 130;

[0087] After the fifth set time period, the drainage device 220 is closed to end the drying process.

[0088] Specifically, the second set time, the third set time and the fifth set time can be measured through experiments so that they are shorter while achieving the above-mentioned effects. Therefore, the process of the drying and washing equipment can be completed at the end of dehydration or a short time after the end, and the overall washing time is basically not increased.

[0089] Furthermore, the present embodiment also provides a control method for a washing device, which is used to heat water of a maximum set value to a set temperature, comprising: the heating cavity 800 is connected to the outer drum 130 of the washing device; before the washing device heats the water in the heating cavity 800, it also comprises: starting the drainage device 220 to discharge the water in the outer drum 130 to the outside; detecting that the water level in the heating cavity 800 drops to the maximum set value, controlling the drainage device 220 to stop running; and starting to heat the water in the heating cavity 800.

[0090] The drainage of the outer cylinder 130 is used for heating, and the heated drainage is used to heat the drainage device 220 for drying.

[0091] In this embodiment, after the drainage device 220 is controlled to stop running, the washing equipment continuously detects the water level in the heating cavity 800. If the detected water level continues to be less than the maximum setting value for a fourth setting time, the water in the heating cavity 800 starts to be heated.

[0092] This ensures that in the process of heating the water in the heating chamber 800, the amount of water exceeding the maximum set value will not enter, and ensures that the water in the heating chamber 800 will not touch the inner drum 160 in operation, that is, the maximum amount of water is preserved for heating without affecting the dehydration work.

[0093] In this embodiment, the washing device controls the drainage device 220 to stop operating and controls the valve member 730 to be turned on.

[0094] This ensures that water will not be further discharged by the siphon of the drainage pipe 320 and the siphon pipe 710, thereby ensuring the effect of the heating chamber 800 on heating water.

[0095] In this embodiment, Figure 2 As shown, the heating structure of the washing device for heating the water of the maximum setting value to the set temperature is specifically as follows: the washing device is preferably a drum washing machine or a washer-dryer, and a downwardly recessed heating chamber 800 is provided at the lower part of the outer drum 130 thereof, the bottom of the heating chamber 800 is connected to the water inlet pipe 210, a heating device 810 is provided inside the heating chamber 800, and a water level detection device 820 is provided on the side wall of the heating chamber 800. Therefore, the washing device can heat the water in the outer drum 130 and use it to dry the drainage device 220.

[0096] In a specific application of this embodiment, the heating device 810 is preferably a heating rod, and the water level detection device 820 is preferably a water level sensor. The detection end electrode of the water level sensor is inserted into the outer drum 130 or the heating chamber 800. The position of the electrode is the water level of the maximum setting value. The water level of the maximum setting value allows the heating chamber 800 to be filled with water while the inner drum 160 rotates without stirring the accumulated water and affecting dehydration. The electrodes are coated with a hydrophobic material. When the water level is equal to or higher than the horizontal height of the electrodes, the two electrodes are connected and send a signal to the sensor of the washing device. When the water level is lower than the horizontal height of the electrodes, the two electrodes are not connected and no signal is sent.

[0097] In this embodiment, Figure 4 As shown, the water of the maximum setting value is heated to the set temperature, specifically: after the last dehydration starts, the drainage device 220 is controlled to operate, the water in the heating chamber 800 is discharged, the water level in the heating container is detected and it is determined whether the water level is lower than the preset water level, the preset water level is the water level of the maximum setting value, if not, the drainage device 220 is controlled to operate, the water in the heating chamber 800 is discharged, until it is determined to be yes, the drainage device 220 is closed, the valve member 730 is controlled to be turned on, so that the drainage device 220 stops draining, and the remaining water is not siphoned out by the drainage pipeline 320 and the siphon pipeline 710. At this time, it means that after several dehydration and drainage in the dehydration process, the water discharged is less and less, and the water level will hardly rise again, and the water volume in the heating chamber 800 that is less than the preset water level will not touch the inner drum 160 in operation;

[0098] The amount of water in the heating chamber 800 is continuously detected, and it is determined whether the amount of water is continuously less than the maximum set value for a fourth set time. If not, the control of the drainage device 220 is returned to operate until it is determined to be yes, and the heating device 810 is started until the water is heated to the set temperature. At this time, it is further ensured that the amount of water in the heating chamber 800 will not touch the inner drum 160 in operation, that is, the maximum amount of water is saved for heating without affecting the dehydration work. Furthermore, the fourth set time has a corresponding relationship with the material and weight of the clothes, which can be measured in the experiment and set as a fixed value of the fourth set time. When the user puts in clothes and selects a program, and the washing machine runs the weighing, the corresponding fixed value of the fourth set time can be obtained according to the weighing value.

[0099] Specifically, the set temperature is a safe temperature below 100° C. at which water does not generate steam, such as 95° C., to prevent steam from returning to the inner drum 160 to increase the moisture content of clothes, to avoid damage to pipelines caused by overheated steam, and to avoid accidental boiling caused by temperature sensor errors.

[0100] In this embodiment, during the last dehydration process of the washing program currently running in the washing device, the drainage device 220 is started, and the heated water is pumped into the drainage device 220, and is simultaneously drained out along the drainage pipe 320 and the siphon pipe 710; after a first set time, the drainage device 220 is closed, and the heated water is controlled to stop flowing into the drainage pipe 320; after the heated water continues to be completely discharged along the siphon pipe 710, the drainage device 220 is opened again.

[0101] The dehydrated water flow is used for heating, and the heated drainage is used to heat the drainage device 220 for drying.

[0102] In this embodiment, at the beginning of the last drainage of the last dehydration of the washing device, if the washing device receives a pump drying instruction, the water will be heated and the water heated to the set temperature will be pumped into the drainage device 220, and the water will be discharged to the outside along the drainage pipe 320 and the siphon pipe 710 at the same time; after the first set time, the drainage device 220 is closed, and the heated water is controlled to stop flowing into the drainage pipe 320; after the heated water continues to be completely discharged along the siphon pipe 710, the drainage device 220 is opened again in a waterless state to exhaust air to the outside.

[0103] The user can control whether to dry and evaporate the residual water in the drainage device 220, thereby reducing the number of drying and evaporation times of the washing device, thereby reducing the energy consumption of the washing device.

[0104] In this embodiment, Figure 5 As shown, in Figure 4 Follow the process shown Figure 3The pump drying program described in this embodiment is used in conjunction with the existing program of the washing device, specifically: at the beginning of the last drainage of the last dehydration of the washing device, if the user chooses to start the pump drying program, that is, the washing device receives the user's pump drying instruction, the pump drying program is executed, otherwise the pump drying program is not executed.

[0105] Furthermore, if the washing device determines that only one drum is to be washed this time and the second drum does not need to be washed continuously, and receives the user's pump drying instruction, the water of the maximum setting value is heated to the set temperature, passed into the drainage device 220, and then the first setting time, the second setting time and the third setting time are executed. If the user's washing machine has a large capacity and there is no or little need to wash two drums in succession, the user can choose to integrate the pump drying program into all existing programs and execute it during the last dehydration, so that the pump drying program is more in line with the user's usage habits.

[0106] Therefore, the user can control whether to dry and evaporate the residual water in the drainage device 220, thereby reducing the number of drying and evaporation times of the washing device, thereby reducing the energy consumption of the washing device.

[0107] Embodiment 2

[0108] like Figure 1 , 2 As shown in 6, this embodiment provides a control method for a washing device on the basis of the first embodiment, and the difference between the control method described in the first embodiment is that the related operations of the sixth set time and the related operations of the seventh set time are arranged between the first set time and the second set time, and the related operations of the sixth set time and the related operations of the seventh set time are used to replace the related operations of the third set time described in the first embodiment, so as to achieve that the heated water is retained in the drainage device 220 for a certain period of time, so that the drainage device 220 is fully heated by the heated water.

[0109] In this embodiment, the valve member 730 connects the siphon pipeline 710 and the drainage pipeline 320. When the valve member 730 is opened, the drainage pipeline 320 and the siphon pipeline 710 are simultaneously connected to the external atmosphere; the portion of the siphon pipeline 710 close to its drainage port is inserted into the interior of the drainage pipeline 320, and the water outlet of the siphon pipeline 710 is not longer than the opening of the drainage pipeline 320;

[0110] In this embodiment, Figure 6As shown, the pump drying program includes: after a first set time, continuously closing the drainage device 220 and continuously controlling the valve component 730 to open for a sixth set time; continuously opening the drainage device 220 again and controlling the valve component 730 to close for a seventh set time; after the seventh set time, closing the drainage device 220 and entering the second set time; during the second set time, the heated water is partially discharged by the siphon of the drainage pipe 320 and then completely discharged by the siphon pipe 710.

[0111] Furthermore, the sixth set time length and the seventh set time length are obtained through experiments, so that the water heated in the six set time lengths can make the shell of the drainage device 220 fully absorb heat and heat up, and the seventh set time length is not shorter than the time it takes for the drainage device 220 to completely discharge the water inside it through the drainage pipe 320.

[0112] Therefore, by the first set time, the cold water in the water inlet pipe 210 is sucked into the drainage device 220 and discharged from the washing equipment through the drainage pipe 320, while the water heated to the set temperature is sucked into the drainage device 220; by the sixth set time, the heated water is retained in the drainage device 220 for a certain period of time, so that the drainage device 220 is fully heated by the water; by the seventh set time, when the heated water in the drainage device 220 is discharged into the drainage pipe 320, a negative pressure environment is formed at the drainage outlet of the siphon pipe 710 when the water flows, so that the siphon pipe 710 generates siphoning, and the drainage pipe 320 and the siphon pipe 710 are connected. 10 is discharged simultaneously, thereby improving the drainage efficiency; by closing the drainage device 220 after the seventh set time, it is achieved that when there is both water and gas in the drainage device 220, the drainage device 220 is prevented from draining water at the same time and the operation of water vapor to generate a loud noise; through the second set time, the siphon pipeline 710 drains the water in the drainage device 220, so that only a very small amount of residual water exists in the drainage device 220; through the fifth set time, only water vapor is discharged, so that the drainage device 220 is completely dried, and the moisture and mold between the inner cylinder 160 and the outer cylinder 130 are avoided, while the drainage device 220 is prevented from draining water at the same time and the operation of water vapor to generate a loud noise.

[0113] Embodiment 3

[0114] like Figures 1 to 6 As shown, this embodiment provides a washing device based on the first embodiment. The washing device is preferably a top-drainage drum washing machine or a washer-dryer, which is provided with the drainage structure and heating structure described in the first embodiment, and is equipped with the control method of the washing device described in the first or second embodiment.

[0115] Therefore, the washing device can control whether the drainage pipe 320 and the siphon pipe 710 are siphoning through the valve member 730 of the drainage structure, so that the drainage volume can be controlled when adding clothes in the middle of the washing process. In addition, the drainage structure and the heating structure are simple in structure, easy to install, with low additional cost and high reliability.

[0116] Embodiment 4

[0117] like Figure 7 As shown, this embodiment provides a washing device on the basis of Embodiment 1, Embodiment 2 and Embodiment 3, and the washing device includes the drainage structure as described in Embodiment 1 and Embodiment 3, and the drainage structure includes: a drainage device 220, having a cavity, the bottom of the cavity is provided with a first opening 222 connected to the siphon pipeline 710, the cavity is also provided with a fourth opening 224 connected to the water inlet pipeline 210, and a filter element 221 is arranged between the first opening 222 and the fourth opening 224 in the cavity; a lint separator 300 is arranged on the drainage pipeline 320, and the lint separator 300 and the filter element 221 are used to separate the water flow carrying impurities including micro-lint respectively; a bending structure is arranged at the highest point of the siphon pipeline 710, and the water inlet of the siphon pipeline 710 is higher than its water outlet; and a valve element 730 for controlling the on-off of the siphon pipeline 710 is arranged on the siphon pipeline 710.

[0118] The wire dust separator 300 and the wire dust collector 400 provided in the drainage pipeline 320 realize the separation and collection of the micro wire dust discharged from the washing device. The first opening 222 is isolated from the water containing wire dust by the filter element 221 of the drainage device 220, so as to ensure that the siphon pipeline 710 will not be blocked. The residual water in the drainage device 220 is drained by the siphon effect, so as to ensure that there is no water inside the washing machine when it is not washing, which is healthier and more hygienic. The siphon effect of the siphon pipeline 710 is interrupted by the valve element 730, so as to ensure that the drainage volume is controllable and the normal mid-way addition operation is ensured when the water level is too high.

[0119] The siphon pipeline 710 is separated from the drainage pipeline 320 from the drainage device 220 to the curved structure, and is inserted into the drainage pipeline 320 at the location of the curved structure, and then extends inside the drainage pipeline 320.

[0120] Specifically, the washing device may be a washing machine or a washer-dryer, preferably a top-drainage washing machine or a washer-dryer.

[0121] Specifically, the wire scrap separator 300 is provided with a filter net with high filtration accuracy that can filter micro wire scraps, and the filter element 221 is a filter net with high filtration accuracy that can filter micro wire scraps. Therefore, by setting the filter element 221 between the first opening 222 and the fourth opening 224, when the drainage device 220 stops running, the water flow in the drainage pipeline 320 falls back and accumulates at the bottom, respectively passes through the wire scrap collector 400 and the filter element 221 to filter out impurities including micro wire scraps, enters the siphon pipeline 710, and is discharged from the washing equipment. Therefore, although the diameter of the siphon pipeline 710 is small, it will not be blocked in long-term use. The water flow in the drainage pipeline 320 is discharged from the washing equipment after the impurities including micro wire scraps are filtered out by the wire scrap separator 300. It is ensured that there are no impurities including micro wire scraps in the water flow discharged from the washing equipment through the siphon pipeline 710 and the drainage pipeline 320, and there is no risk of clogging in the pipelines.

[0122] In detail, the process of the siphon effect generated by the siphon pipe 710 is as follows: when the drainage device 220 drains water, there is water at the water inlet of the siphon pipe 710, and the water flow in the drainage pipe 320 flows through the water outlet of the siphon pipe 710 to form a negative pressure environment at the water outlet, so that water flows into the siphon pipe 710 and the air in the siphon pipe 710 is discharged; when there is water at the water inlet of the siphon pipe 710 and the water outlet is not liquid-sealed, since the water inlet is higher than the water outlet, according to the Bernoulli equation of fluid mechanics, it can be known that a pressure difference is formed at the inlet and outlet of the siphon pipe 710, and the water flow is pushed to continuously move toward the water outlet, forming a siphon effect, and then the residual water in the drainage device 220 is continuously discharged until the residual water is drained. In a specific application of this embodiment, the water outlet of the siphon pipeline 710 and the opening of the drainage pipeline 320 are inserted into a floor drain below the bottom of the shell of the washing device, so that the water inlet is higher than the water outlet.

[0123] Therefore, by inserting the siphon line 710 into the drainage line 320, the impurities including micro-line scraps discharged from the upper drainage drum washing machine are filtered, and the residual water in the drainage device 220 is drained, so that after the upper drainage drum washing machine is washed, there is basically no residual water in the washing machine, and the remaining trace water will soon evaporate and the interior will become dry. It does not breed bacteria and odor, and there is no micro-line scraps in the drainage, which is green and environmentally friendly. In addition, the housing 110 of the washing machine only needs to be provided with one drain port, which reduces the cost of adding the outlet of the siphon line 710 on the housing 110 and inserting the floor drain joint, and is convenient for users to arrange the drainage line layout. While reducing the work and cost of arranging the drainage line for users, compared with the water outlet of two pipes, it can also reduce the risk of damage. Since the siphon line 710 has a smaller diameter, it occupies less internal space of the drainage line 320, so that the drainage speed of the drainage line 320 is not affected.

[0124] In summary, by first separating the siphon pipe 710 from the drainage pipe 320 and then inserting it into the interior of the drainage pipe 320, the lint separator 300 set in the drainage pipe 320 does not conflict with the siphon pipe 710, thereby achieving the filtration of micro-lint in the discharged water flow, and triggering the siphon effect by drainage, so that the residual water in the drainage device 220 is drained.

[0125] In this embodiment, the siphon pipeline 710 is connected to a multi-channel 720 at a position between its water inlet and the curved structure; the multi-channel 720 is also connected to the drainage pipeline 320; the multi-channel 720 includes a valve component 730, and the valve component 730 is used to control the connection and disconnection of the siphon pipeline 710 and the drainage pipeline 320 with the atmosphere at the multi-channel 720.

[0126] Through the multi-head channel 720 and the valve member 730, the control of the conduction and cutoff of the siphon pipe 710 is realized. For example, when adding clothes in the middle and the water level is too high and drainage is required, the siphon pipe 710 is cut off and no water flows through the siphon pipe 710, thereby avoiding the formation of a siphon effect in the siphon pipe 710 and the drainage pipe 320.

[0127] In this embodiment, an air duct is provided on the multi-head channel 720, and the air duct connects the siphon pipeline 710 and the connecting piece 330. The air duct has an air inlet connected to the external atmosphere, and the valve component 730 for controlling the conduction and blocking thereof is provided at the air inlet; the connecting piece 330 is connected to the drainage pipeline 320.

[0128] By controlling whether the air inlet introduces the atmosphere into the air duct, it is possible to simultaneously control whether the siphon pipeline 710 and the drainage pipeline 320 produce a siphon effect, thereby achieving accurate control of the amount of discharged water.

[0129] By controlling whether the air inlet is introduced into the air duct, it is possible to simultaneously control whether the siphon line 710 and the drainage line 320 generate a siphon effect, thereby achieving accurate control of the amount of water discharged. Specifically, during the washing process of the washing machine, the user adds clothes to the inner drum 160 of the washing machine. Because the water level in the inner drum 160 is too high and needs to be drained, the amount of water discharged needs to be accurately controlled, and the siphon effect of the siphon line 710 and the drainage line 320 needs to be stopped.

[0130] Through the multi-head channel 720 and the valve member 730, the control of the connection and cutoff of the siphon pipe 710 and the drainage pipe 320 with the atmosphere is realized. For example, when the water level is too high and drainage is required when adding clothes in the middle, the siphon pipe 710 and the drainage pipe 320 are connected to the atmosphere. In this case, when draining, air enters the siphon pipe 710 and the drainage pipe 320, and no water flows through the siphon pipe 710. Although there is normal water flow in the drainage pipe 320, a large amount of air is mixed in. Through such a setting, the formation of a siphon effect in the siphon pipe 710 and the drainage pipe 320 is avoided, and the drainage device 220 is ensured to stop, and all drainage stops immediately, thereby avoiding the washing water from being continuously drawn out along the siphon pipe 710 during the subsequent washing process, affecting the normal washing process.

[0131] Specifically, Figure 7 As shown, the multi-channel 720 is a four-way component, the air duct is a channel in the four-way component, the valve member 730 is a solenoid valve, the connector 330 is a pipe joint member, the air inlet is an exposed pipe port of the four-way component, the solenoid valve is arranged at the exposed pipe port, and the four-way component is provided with two openings connecting the upper and lower sections of the siphon pipeline 710, an air inlet connecting the external atmosphere and an opening connecting the connector 330. The multi-channel 720 is arranged at a position close to the connector 330, and the connector 330 is arranged at a position close to the highest point of the drainage pipeline of the washing device. The multi-channel 720 is connected to the connector 330 through a short, curved connecting pipeline 770, so that the multi-channel 720 is connected to the drainage pipeline 320 through the connecting pipeline 770 and the connector 330.

[0132] Specifically, the third curved portion 760 is located near the opening of the upper portion of the washing device. More specifically, the third curved portion 760 is led out to the outside through the drain port on the upper portion of the washing device.

[0133] In detail, when the multi-head channel 720 introduces atmosphere into the siphon pipe 710 and the third bend 760, the water in the drainage pipe 320 that has not flowed to the connecting piece 330 will flow back into the drainage device 220. In the siphon pipe 710, since the density of the atmosphere is lower than the density of water, part of the water in the siphon pipe 710 that flows through the highest point of the pipe continues to flow out, and the water below the highest point flows back into the drainage device 220.

[0134] In this embodiment, a connector 330 is provided on the drainage pipeline 320 , and the connector 330 is in communication with the connecting pipeline 770 ; the curved structure of the connecting pipeline 770 is at least partially inserted into the interior of the connector 330 .

[0135] The cost of adding the siphon pipeline 710 is reduced.

[0136] Specifically, the bending structure of the siphon pipeline 710 includes a first bending portion 740 and a second bending portion 750; the siphon pipeline 710 partially extends vertically upward, and bends to one side at the end of the extension to the highest point in the vertical direction, forming the first bending portion 740; the siphon pipeline 710 bends downward from the highest point to form the second bending portion 750. Through the first bending portion 740 and the second bending portion 750, the siphon pipeline 710 is able to pass the highest point upward and then pump water downward.

[0137] Specifically, Figure 7 As shown, the bending radius of the second curved portion 750 is greater than the bending radius of the first curved portion 740, which reduces the resistance of the pipe of the second curved portion 750 draining water downward, thereby making the water absorption effect of the siphon action better.

[0138] In this embodiment, the first curved portion 740 is at least partially inserted into the interior of the connecting member 330 , and the second curved portion 750 is disposed in the connecting member 330 or the drainage pipe 320 .

[0139] The siphon pipeline 710 is provided with a first curved portion 740 and a second curved portion 750 inside the connector 330 or in the drainage pipeline 320 , thereby further reducing the cost of adding the siphon pipeline 710 .

[0140] In this embodiment, the second curved portion 750 is disposed in the drainage pipe 320, and the drainage pipe 320 forms a third curved portion 760 at the second curved portion 750. The drainage pipe 320 is disposed in accordance with the upper drainage type washing device.

[0141] In detail, when the drainage device 220 is running, water is discharged into the drainage pipe 320 to expel the internal air, and the water inlet of the drainage pipe 320 is higher than its opening, thereby causing a siphon effect in the drainage pipe 320. When the drainage device 220 stops, the water flow in the drainage pipe 320 will continue to be discharged from the washing equipment due to the siphon effect and will not stop, and cannot be controlled.

[0142] In this embodiment, the third bend 760 is located at the highest point of the drainage pipeline of the washing equipment; the drainage pipeline 320 extends from the third bend 760 to the water outlet of the siphon pipeline 710 , and forms a pipe-in-pipe structure with the siphon pipeline 710 .

[0143] The second curved portion 750 is disposed in the drainage pipe 320 to form a pipe-in-pipe structure with the drainage pipe. Further, the second curved portion 750 forms a pipe-in-pipe structure with the drainage pipe 320 having the same curvature.

[0144] The drainage pipeline 320 is arranged in accordance with the upper drainage type washing equipment, and the cost of adding the siphon pipeline 710 is reduced through the pipe-in-pipe structure.

[0145] In detail, the highest point of the drainage pipeline of the upper drainage type washing equipment is set at the upper part of the washing equipment, and has a water outlet pipeline bent and extended to the outside.

[0146] In this embodiment, the siphon pipe 710 is located at the water outlet inside the drainage pipe 320 and is not longer than the opening of the drainage pipe 320 outside. Since the water outlet of the siphon pipe 710 is not longer than the opening of the drainage pipe 320 outside, the water in the drainage pipe 320 flows through the water outlet of the siphon pipe 710 to form a negative pressure environment.

[0147] By making the outlet of the siphon pipe 710 not longer than the opening of the drainage pipe 320 outside the siphon pipe 710, the water in the drainage pipe 320 flows through the outlet of the siphon pipe 710 to form a negative pressure environment, so that the water in the drainage device 220 is sucked into the siphon pipe 710. In detail, according to the Bernoulli principle of fluid mechanics, the water flow velocity at the outlet is faster, which reduces the air pressure in the outlet, thus forming a negative pressure environment at the outlet, and making the pressure at the water inlet of the siphon pipe 710 greater than the outlet.

[0148] Furthermore, the drainage pipe 320 includes an inner drainage pipe 321 and an outer drainage pipe 322. The inner drainage pipe 321 connects the connecting piece 330 and the drainage device 220. The outer drainage pipe 322 forms a pipe-in-pipe structure with the connecting piece 330 and the siphon pipe 710. The diameter of the outer drainage pipe 322 is slightly larger than the diameter of the inner drainage pipe 321, thereby achieving a pipe-in-pipe structure that does not reduce the amount of water discharged from the drainage pipe 320.

[0149] In this embodiment, the wire scrap collector 400 is connected to the wire scrap separator 300, and the wire scrap separator 300 discharges the impurities including micro-wire scraps filtered out by the wire scrap collector 400 along with the water flow; the water flow is filtered in the wire scrap collector 400 and then discharged into the drainage device 220, and the wire scrap collector 400 is connected to the third opening 225 of the cavity of the drainage device 220, and the third opening 225 and the first opening 222 are located on the same side of the filter element 221.

[0150] Specifically, the drainage device 220 is a drainage pump. The outer drum 130 of the washing equipment is connected to the fourth opening 224 of the cavity of the drainage device 220 through the first pipeline 210. The fourth opening 224 and the second opening 223 are located on the same side of the filter element 221. The drainage device 220 is provided with a water pump motor 240 near the second opening 223. The drainage motor 240 is used to pressurize the water flow and send it into the drainage pipeline 320, so that the water pressure at the second opening 223 is larger and the pressure at the third opening 225 is smaller, thereby enhancing the separation effect of the water in the filter 401.

[0151] Specifically, the wire dust collector 400 is located below the wire dust separator 300, and the drainage device 220 is located below the wire dust collector 400. When the drainage device 220 stops running, the accumulated water in the wire dust separator 300 falls back, and the impurities inside are flushed into the wire dust collector 400. After the wire dust collector 400 filters and collects the impurities, the water flows back into the cavity of the drainage device 220. Automatic backflow of accumulated water and automatic cleaning of the wire dust separator 300 by falling accumulated water are achieved.

[0152] In this embodiment, the ratio of the diameter of the siphon pipe 710 to the diameter of the drainage pipe 320 is a fixed value. Specifically, since there are at least three drainage processes in a standard washing, including one drainage process of washing and two drainage processes of rinsing, in order to avoid the situation where the siphon effect of the siphon pipe 710 has not ended after drainage, but the next water inlet node has already started, resulting in continuous drainage of the washing equipment, the diameter of the siphon pipe 710 needs to be set larger to ensure that the siphon drainage has stopped before the next water inlet. Since the diameter and the highest point of the drainage pipe 320 determine the amount of residual water in the drainage device 220, the ratio of the diameter of the siphon pipe 710 to the diameter of the drainage pipe 320 is determined through experiments, which can ensure that the siphon effect of the siphon pipe 710 takes a short time to drain the residual water of the drainage device 220 and will not affect the next water inlet. In this embodiment, the lint separator 300 provided in the drainage pipeline 320 and the filter element in the lint collector 400 are used to filter and collect the micro-lint in the water flow discharged from the washing device, and the residual water in the drainage device 220 is drained by the siphon effect. The siphon drainage of the siphon pipeline 710 and the drainage pipeline 320 is interrupted by the valve element 730 to ensure that the drainage volume is controllable and the normal midway clothing adding operation can be performed when the water level is too high; the siphon pipeline 710 and the drainage pipeline 320 are connected by the air duct of the multi-head channel 720, and it is controlled whether the air inlet of the air duct is connected to the air duct, so as to realize the simultaneous control of the siphon effect of the siphon pipeline 710 and the drainage pipe 320, thereby realizing the control of the discharged water volume; the impurities filtered by the lint separator 300 are collected, and the water flow rushing into the lint collector 400 can flow back to the drainage device 220 to be sucked in by the siphon pipeline 710 and discharged from the washing device.

[0153] In this embodiment, micro-lint filtration of the water flow discharged from the washing device is achieved, the residual water in the drainage device 220 is drained by the siphon effect, and the siphon effect of the siphon pipeline 710 and the drainage pipeline 320 is interrupted by the valve member 730 to ensure normal mid-way clothing addition operation when the water level is too high; through the multi-head channel 720, the connection and cutoff of the siphon pipeline 710 and the drainage pipeline 320 with the atmosphere are controlled. For example, when adding clothes midway because the water level is too high and drainage is required, the siphon pipeline 710 and the drainage pipeline 320 are connected to the atmosphere to avoid the formation of a siphon effect in the siphon pipeline 710 and the drainage pipeline 320, and the drainage device 220 stops draining and stops draining synchronously to avoid the washing water being continuously pumped out along the siphon pipeline 710 and the drainage pipeline 320 during the subsequent washing process.

[0154] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
