The specific type of the laundry treatment apparatus according to the embodiment of the present application is not limited, and may be, for example, a pulsator type laundry treatment apparatus, and may also be a drum type laundry treatment apparatus, such as a drum washer/dryer, a drum dryer, and the like.

In one embodiment, with reference to fig. 1, the barrel assembly 2 includes an outer barrel 22 and an inner barrel 21 rotatably disposed in the outer barrel 22. The space inside the inner drum 21 is a laundry treating chamber 2 a.

The specific structure of the steam generator 11 is not limited as long as water can be heated to generate steam when heated. That is, the steam generator 11 in the embodiment of the present application may be implemented by using a technology known in the art, and will not be described in detail herein.

In one embodiment, referring to fig. 2, the water storage cavity 13a is located on the water inlet waterway 12, and water in the water inlet waterway 12 flows through the water storage cavity 13 a. Specifically, the water storage cavity 13a includes a water inlet 13b, a first water outlet 13c and a second water outlet 13d, and the water inlet 13b, the first water outlet 13c and the second water outlet 13d are all communicated with the water storage cavity 13 a.

The first water outlet 13c communicates with the water inlet 11a of the steam generator 11.

In another embodiment, referring to fig. 3, the clothes treating apparatus includes a branch path 17, the branch path 17 communicates with the water storage chamber 13a and the water inlet path 12, and a part of water in the water inlet path 12 enters the water storage chamber 13a through the branch path 17. Specifically, the water storage member 13 includes a water inlet 13b and a first water outlet 13c, wherein the water inlet 13b is communicated with the branch 17, and the first water outlet 13c is communicated with the water inlet 11a of the steam generator 11. That is, in this embodiment, a part of the water in the inlet waterway 12 is divided into the water storage cavity 13a, and the water storage cavity 13a has substantially no influence on the flow of the water in the inlet waterway 12.

In the above two embodiments, the laundry treating apparatus includes the flow passage 16 communicating the water inlet 11a and the first water outlet 13 c.

It should be noted that, when the flow passage 16 is a straight flow passage, that is, the water inlet 11a and the first water outlet 13c are not in communication, any device capable of intercepting the water flow in the flow passage 16 is not provided in the flow passage 16. In this embodiment, the water in the water storage chamber 13a is automatically replenished into the steam generator 11 by means of the air pressure balance. Specifically, the top of the water storage member 13 is provided with an air hole communicated with the atmosphere, when the water in the steam generator 11 is gradually consumed due to the generation of steam, the water level in the steam generator 11 gradually decreases, and since the air pressure borne by the liquid level in the steam generator 11 and the liquid level in the water storage cavity 13a is approximately the atmospheric pressure, the water in the water storage cavity 13a can be automatically supplemented into the steam generator 11, so that the liquid level in the steam generator 11 is approximately the same as the liquid level in the water storage cavity 13 a.

In one embodiment, the water inlet 11a is located at a lower portion of the steam generator 11 to reduce the height of the water inlet 11a as much as possible. The first water outlet 13c is located at a lower portion of the water storage member 13 to reduce the height of the first water outlet 13c as much as possible.

It should be noted that in some embodiments, an overflow port is provided at the upper portion of the water storage member 13, and when the excess water in the water storage chamber 13a can be discharged through the overflow port.

In another embodiment, referring to fig. 3, the laundry treating apparatus includes a one-way control member 14, and the one-way control member 14 is disposed on the flow passage 16 to allow water in the water storage chamber 13a to flow to the steam generator 11 in a one-way direction. That is, the water in the water storage chamber 13a can enter the steam generator 11 through the flow passage 16, and the water in the steam generator 11 cannot flow back into the water storage chamber 13 a. In this way, the water heated in the steam generator 11 can be prevented from flowing backwards into the water storage cavity 13a, on one hand, heat loss can be avoided, and on the other hand, the manufacturing requirements of the water storage member 13 can be reduced, for example, the water storage member 13 does not need to have high temperature resistance and explosion-proof performance, so the water storage member 13 can be a common plastic product.

It will be appreciated that the particular form of the one-way control member 14 is not limited as long as it is capable of controlling the flow of water in one direction.

Illustratively, in one embodiment, the one-way control 14 is a hydraulic one-way valve. It should be noted that the specific structural form of the hydraulic check valve is not limited.

In another embodiment, the one-way control 14 is a water pump. When the water pump is turned on, water in the water storage chamber 13a can enter the steam generator 11, and when the water pump is turned off, the water flow in the flow passage 16 is cut off, and water in the water storage chamber 13a cannot enter the steam generator 11. No matter the water pump is turned on or off, the water in the steam generator 11 cannot enter the water storage chamber 13 a. In this embodiment, water is pumped into the steam generator 11 by the water pump, so that water can be quantitatively supplied to the steam generator 11, and the amount of water supplied to the steam generator 11 can be accurately controlled.

The specific type of water pump is not limited as long as the volume is less and the installation is convenient and the water pump can. In an exemplary embodiment, the water pump is a peristaltic pump, and the peristaltic pump has the advantages that fluid only contacts the pump tube and does not contact the pump body, the precision is high, the stability and the precision are high, the self-priming capability is good, idling can be achieved, backflow can be prevented, and the like.

In one embodiment, the steam generated by the steam generator 11 may be directly directed to the laundry treating chamber 2a through a pipe. In detail, a duct may be connected to the steam outlet 11b of the steam generator 11, and the end of the duct directly sprays steam to the laundry treating chamber 2 a.

In another embodiment, the clothes treating apparatus has a drying tunnel 4a for guiding hot air flow into the clothes treating cavity 2a, and in particular, hot air flow in the drying tunnel 4a enters the clothes treating cavity 2a to dry clothes in the clothes treating cavity 2 a. It is understood that, in order to form the hot air flow, a heating member 41 and a fan 42 are provided in the circulation duct 4, the heating member 41 being for heating air, and the fan 42 being for generating a directional flow of air. The specific structural form of the heating member 41 is not limited, and resistance wire heating may be adopted, and a condenser in a heat pump system may also be adopted as the heating member 41.

In one embodiment, the steam outlet 11b of the steam generator 11 is communicated with the drying tunnel 4a, and the steam generated by the steam generator 11 is introduced into the laundry treating chamber 2a through the drying tunnel 4 a. In this embodiment, when saturated steam is generated in the steam generator 11, the saturated steam enters the drying tunnel 4a, and superheated steam can be formed through secondary heating of the drying tunnel 4 a. On one hand, when the clothes are dried by the superheated steam, the problems of wrinkles, deformation and the like are not easy to generate due to the fact that the surfaces of the clothes are wet and the drying stress is small, and moreover, the superheated steam drying is free of oxidation reaction, the clothes cannot fade, and the drying quality of the clothes is improved; on the other hand, the specific heat and the heat transfer coefficient of the superheated steam are larger than those of air, and meanwhile, the mass transfer resistance of the superheated steam in the drying medium can be ignored, so that the moisture migration speed is high, and the time for drying clothes can be obviously reduced; on the other hand, the temperature of the superheated steam for drying the clothes is the boiling point temperature of water, so that bacteria and other toxic microorganisms on the clothes can be killed, and the effect of sterilizing the clothes is achieved.

It should be noted that the air flow in the drying tunnel 4a may be a non-circulating air flow. Specifically, ambient air enters the drying tunnel 4a under the suction of the fan 42, is heated by the heating element 41 in the drying tunnel 4a and then enters the clothes treatment cavity 2a, and the hot air flow in the clothes treatment cavity 2a is directly discharged to the atmosphere.

Illustratively, in one embodiment, the laundry processing apparatus includes a circulating air duct 4 and a condensing device disposed on the circulating air duct 4, the drying duct 4a is a part of the circulating air duct 4, specifically, the drying duct 4a is located downstream of the circulating air duct 4 along the airflow flowing direction, and the water inlet waterway 12 guides water flow to the condensing device to cool and dehumidify the airflow in the circulating air duct 4. That is, in this embodiment, the air flow in the circulating air duct 4 is cooled and dehumidified by water cooling, and the water inlet waterway 12 provides the condensed water for the condensing device. For example, referring to FIG. 2, the water flow at the right arrow in FIG. 2 flows to the condensing unit. For another example, referring to fig. 3, the water flow at the lower arrow in fig. 3 flows to the condensing device.

The process of drying the laundry by the laundry treating apparatus: the hot dry air in the drying tunnel 4a enters the clothes processing cavity 2a, the hot dry air flows through the surface of the wet clothes to perform heat and moisture exchange with the wet clothes, absorbs moisture in the clothes to become wet hot air flow, the wet hot air flow is discharged out of the clothes processing cavity 2a and enters the circulating air duct 4, the wet hot air flow is cooled into low-temperature low-humidity air after passing through the condensing device, and the low-temperature low-humidity air enters the drying tunnel 4a and is heated to be hot dry air to enter the next circulation. The clothes are continuously and efficiently dried by the circulation operation.

It should be noted that, in an embodiment, the water introduced into the condensing device by the water inlet waterway 12 may directly contact with the air flow in the circulating air duct 4, and the water and the air flow perform heat convection to further cool and dehumidify the air flow. In another embodiment, the water introduced into the condensing device by the water inlet waterway 12 does not directly contact with the air flow, the water cools the condensing device itself, and the air flow is cooled and dehumidified by heat exchange between the condensing device and the air.

Taking the direct contact of the air flow and the condensed water as an example, the cooling and dehumidifying principle of the air flow in the circulating air duct 4 is as follows: the wet hot air flow is contacted with the condensed water to carry out heat exchange, the condensed water absorbs the heat in the wet hot air flow, the water vapor in the wet hot air flow is separated out from the air flow due to the temperature reduction and condensed into water drops, and the water drops are mixed into the condensed water and taken away by the condensed water, so that the effect of dehumidifying and cooling the wet hot air flow is achieved, and the air flow is relatively low-temperature dry air flow after being cooled and dehumidified by the condensing device.

In one embodiment, the water inlet circuit 12 is in communication with the laundry treatment chamber 2a to supply the washing water to the laundry treatment chamber 2a, for example, as shown in fig. 2, the water flow at the right arrow of fig. 2 flows to the laundry treatment chamber 2 a. For another example, referring to fig. 3, the water flow at the arrow in the lower part of fig. 3 flows to the laundry treating chamber 2 a. It will be appreciated that a shower head may be provided at the end of the water inlet circuit 12, through which water is sprayed into the laundry treatment chamber 2 a. In this embodiment, as long as the laundry treating apparatus washes laundry, water can be supplied to the water storage chamber 13a, and the water storage chamber 13a can be kept in a state of no water shortage for a long time.

In one embodiment, referring to fig. 1, a detergent box 19 is disposed on the water inlet circuit 12, and the water in the water inlet circuit 12 flows through the detergent box 19 and then enters the laundry treatment chamber 2 a. It should be noted that the branch flow path 17 in fig. 3 does not communicate with the space inside the detergent box 19, but is branched and led out from the water inlet of the detergent box 19 through a multi-way joint.

In one embodiment, the laundry treating apparatus includes a water inlet switching valve 18 provided on the water inlet path 12, and the laundry treating apparatus has an air wash mode in which the water inlet switching valve 18 is in a closed state by default. When the laundry treating apparatus is in the air washing mode, the water inlet switch valve 18 is not turned on by default, and the water in the water storage chamber 13a is used to replenish the water to the steam generator 11, thereby preventing the water inlet path 12 from supplying water to the laundry treating chamber 2a to wet the laundry.

In one embodiment, the volume of the water storage cavity 13a is 1-6 times of the water amount required by the clothes treatment apparatus in the single air washing mode. Specifically, the amount of water required for the design of the laundry treating apparatus to perform the primary air washing mode is V1, and the volume of the water storage chamber 13a is 1-6 times of V1. That is, even if water is not supplied to the water storage cavity 13a halfway, the water storage amount of the water storage cavity 13a can satisfy the air washing mode of the clothes treatment device for 1-6 times. .

Exemplarily, the volume of the water storage cavity 13a is 3-6 times of the water amount required by the clothes treatment equipment in the single air washing mode, so that frequent water replenishing to the water storage cavity 13a can be avoided, the control operation is simplified, and the overlarge occupation of the overlarge installation space due to the overlarge volume of the water storage cavity 13a can be avoided.

In one embodiment, the clothes treatment equipment comprises a control main board, a liquid level detection device 15 and a water inlet switch valve 18 arranged on the water inlet waterway 12, wherein the liquid level detection device 15 and the water inlet switch valve 18 are both electrically connected with the control main board, and the liquid level detection device 15 is used for detecting the liquid level of the water storage cavity 13a and sending a liquid level signal to the control main board. The control mainboard is configured to: when the liquid level of the water storage cavity 13a is lower than a first preset value, the water inlet switch valve 18 is controlled to be opened to replenish water to the water storage cavity 13 a. The first preset value is an alarm value for representing water shortage of the water storage cavity 13a, and when the liquid level of the water storage cavity 13a is lower than the first preset value, the water storage cavity 13a is in a water shortage state, and water should be supplemented to the water storage cavity 13a in time. In this embodiment, the liquid level of the water storage cavity 13a is monitored by the liquid level detection device 15, and automatic water supply can be realized according to the monitoring result, so that dry burning of the steam generator 11 is avoided.

The specific type of the liquid level detection device 15 is not limited. The liquid level detection device 15 may detect the liquid level of the water storage chamber 13a based on a pressure method, a buoyancy method, an electrical method, a thermal method, or the like.

It can be understood that the laundry treating apparatus may further include an alarm unit electrically connected to the control main board, and when the liquid level of the water storage chamber 13a is lower than the first preset value, the alarm unit outputs an alarm signal to prompt the user that the water storage chamber 13a is in a water shortage state. The specific type of the alarm unit is not limited, and may be a bulb, a speaker, a display panel, etc., and is not limited herein.

In one embodiment, the control motherboard is configured to: when the accumulated times of the continuous and independent opening of the air washing mode is more than the preset times, the water inlet switch valve 18 is controlled to be opened to replenish water to the water storage cavity 13 a. It should be noted that the cumulative number of times that the air wash mode is continuously and individually turned on means the total number of times that the air wash mode is turned on when the laundry treatment apparatus is turned on only the air wash mode and does not turn on any washing program that requires water injection into the laundry treatment chamber 2a, and it should be noted that the cumulative number of times is cleared as long as the laundry treatment apparatus turns on the washing program that requires water injection into the laundry treatment chamber 2 a. That is, even if water is not replenished halfway, the water storage amount in the water storage chamber 13a can supply the air washing mode in which the laundry treating apparatus performs the preset number of times, and it is not necessary to separately replenish water to the water storage chamber 13a without exceeding the preset number of times. Thus, frequent water supply to the water storage chamber 13a can be avoided.

It should be noted that the preset number may be determined according to the capacity of the water storage chamber 13a and the amount of water required to perform the single air washing mode, for example, the preset number may be 1, 2, 3, 4, 5, 6, and the like.

In one embodiment, the control motherboard is configured to: and controlling the water inlet switch valve 18 to be closed after the water inlet switch valve 18 is opened for a preset time. The opening time of the water inlet switching valve 18 is required to ensure that sufficient water is supplied to the water storage chamber 13 a. Illustratively, the preset duration satisfies: within a preset time, the designed water flow entering the water storage cavity 13a from the water inlet waterway 12 is 0.8-1.0 of the volume of the water storage cavity 13a, and it can be understood that the designed water flow is a parameter defined in a design stage, so that the water flow actually entering the water storage cavity 13a does not need to be detected in the use process.

In another embodiment, the control motherboard is configured to: and when the liquid level of the water storage cavity 13a reaches a second preset value, controlling the water inlet switch valve 18 to be closed, wherein the second preset value is greater than the first preset value. In this embodiment, by detecting the liquid level in the water storage chamber 13a, when the liquid level reaches the second preset value, it indicates that the water amount in the water storage chamber 13a is sufficient.

The specific structural form of the water storage 13 is not limited, and the water storage 13 may be in the shape of a box, a sphere, a column, or the like.

and when the liquid level of the water storage cavity 13a is lower than the first preset value, determining that the water storage cavity 13a needs to be replenished. That is, whether the water storage chamber 13a requires refilling is determined depending on the liquid level height of the water storage chamber 13 a.

In one embodiment, step S2 includes: the laundry treating apparatus has an air washing mode, and when the cumulative number of times of the air washing mode being continuously and individually turned on is greater than a preset number of times, it is determined that the water storage chamber 13a requires water supplement. It should be noted that the cumulative number of times that the air wash mode is continuously and individually turned on means the total number of times that the air wash mode is turned on when the laundry treatment apparatus is turned on only the air wash mode and does not turn on any washing program that requires water injection into the laundry treatment chamber 2a, and it should be noted that the cumulative number of times is cleared as long as the laundry treatment apparatus turns on the washing program that requires water injection into the laundry treatment chamber 2 a. That is, even if water is not replenished halfway, the water storage amount in the water storage cavity 13a can supply the air washing mode of the clothes treatment apparatus for the preset number of times, and under the condition that the preset number is not exceeded, water does not need to be replenished to the water storage cavity 13a independently, so that frequent water replenishment to the water storage cavity 13a can be avoided. In this embodiment, even if the water level in the water storage chamber 13a is not lower than the first preset value, water is still supplied into the water storage chamber 13a, so as to prevent the water remaining in the water storage chamber 13a from being insufficient to support the current air washing mode.

In an embodiment, referring to fig. 5, the control method further includes:

s31: the water inlet open/close valve 18 is controlled to be closed after the water inlet open/close valve 18 is opened for a preset time period. The opening time of the water inlet switching valve 18 is required to ensure that sufficient water is supplied to the water storage chamber 13 a. Illustratively, the preset duration satisfies: within a preset time, the designed water flow entering the water storage cavity 13a from the water inlet waterway 12 is 0.8-1.0 of the volume of the water storage cavity 13 a. It will be appreciated that the design water flow is a parameter defined during the design phase and therefore there is no need to detect the actual water flow into the water storage chamber 13a during use.

In an embodiment, referring to fig. 6, the control method further includes:

s32: when the liquid level of the water storage cavity 13a reaches a second preset value, the water inlet switch valve 18 is controlled to be closed. In this embodiment, by detecting the liquid level in the water storage chamber 13a, when the liquid level reaches the second preset value, it indicates that the water amount in the water storage chamber 13a is sufficient, and at this time, the water inlet switch valve 18 may be closed.

The various embodiments/implementations provided herein may be combined with each other without contradiction.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
