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, or a drum type laundry treatment apparatus, for example, a drum washing and drying integrated machine, a drum dryer, or the like.
In one embodiment, referring to fig. 1, the barrel assembly 2 includes an outer barrel 22 and an inner barrel 21 rotatably disposed within the outer barrel 22. The space inside the inner tub 21 is a laundry treating chamber 2a.
The specific structure of the steam generator 11 is not limited as long as it is capable of heating water to generate steam at the time of heating. That is, the steam generator 11 in the embodiment of the present application may be implemented by the technology existing in the prior art, and will not be described herein.
In one embodiment, referring to fig. 2, the water storage cavity 13a is located on the water inlet channel 12, and water in the water inlet channel 12 flows through the water storage cavity 13a. Specifically, the water storage chamber 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 in communication with the water storage chamber 13a. The water inlet waterway 12 includes a first sub-passageway 121 and a second sub-passageway 122, the first sub-passageway 121 being located upstream of the water storage chamber 13a in the direction of flow of water, the second sub-passageway 122 being located downstream of the water storage chamber 13a, the end of the first sub-passageway 121 being in communication with the water inlet 13b, the inlet of the second sub-passageway 122 being in communication with the second water outlet 13 d. 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 diversion branch 17, the diversion branch 17 communicates with the water storage chamber 13a and the water inlet channel 12, and part of water in the water inlet channel 12 enters the water storage chamber 13a through the diversion branch 17. Specifically, the water storage member 13 includes a water inlet 13b and a first water outlet 13c, wherein the water inlet 13b communicates with the shunt branch 17, and the first water outlet 13c communicates with the water inlet 11a of the steam generator 11. That is, in this embodiment, a part of the water in the water intake waterway 12 is branched into the water storage chamber 13a, and the water storage chamber 13a has substantially no influence on the flow of the water in the water intake waterway 12.
In the above two embodiments, the laundry treating apparatus includes the flow passage 16 communicating with the water inlet 11a and the first water outlet 13 c.
When the flow channel 16 is a direct flow channel, that is, the water inlet 11a and the first water outlet 13c are unconditionally connected, no device capable of cutting off the water flow in the flow channel 16 is provided in the flow channel 16. In this embodiment, automatic water replenishment of the steam generator 11 with water in the water storage chamber 13a is achieved by means of air pressure balance. Specifically, the top of the water storage member 13 is provided with an air hole communicating 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 the water level in the water storage chamber 13a is automatically fed into the steam generator 11 because the air pressure borne by the liquid level in the steam generator 11 and the liquid level in the water storage chamber 13a are both approximately the atmospheric pressure, so that the liquid level in the steam generator 11 is approximately the same as the liquid level in the water storage chamber 13a.
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, the upper portion of the water storage member 13 is provided with an overflow port, and when the water in the water storage chamber 13a is discharged through the overflow port.
In another embodiment, referring to fig. 3, the laundry treating apparatus includes a unidirectional control member 14, and the unidirectional control member 14 is disposed on the flow passage 16 such that water in the water storage chamber 13a flows unidirectionally to the steam generator 11. 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 13a. In this way, the heated water in the steam generator 11 can be prevented from flowing back into the water storage chamber 13a, on the one hand, heat loss is avoided, and on the other hand, the manufacturing requirement 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 resistance, and therefore the water storage member 13 can be a common plastic product.
It will be appreciated that the particular form of unidirectional control 14 is not limited so long as the unidirectional flow of water is controlled.
Illustratively, in one embodiment, the check control 14 is a hydraulic check valve. It should be noted that the specific structural form of the hydraulic check valve is not limited.
In another embodiment, the unidirectional 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, water in the flow channel 16 is cut off, and water in the water storage chamber 13a cannot enter the steam generator 11. No matter whether the water pump is turned on or off, water in the steam generator 11 can enter the water storage chamber 13a. In this embodiment, since the water is pumped into the steam generator 11 by the water pump, the water can be quantitatively supplied to the steam generator 11, and the water supply amount to the steam generator 11 can be controlled more accurately.
The specific type of the water pump is not limited, and the water pump is small in size, convenient to install and capable of pumping water. In an exemplary embodiment, the water pump is a peristaltic pump, and the peristaltic pump has the advantages of having fluid only in contact with the pump tube, not in contact with the pump body, high precision, high stability and precision, good self-absorption capability, idling, backflow prevention 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. Specifically, a duct may be connected to the steam outlet 11b of the steam generator 11, and the end of the duct directly sprays steam into the laundry treating chamber 2a.
In another embodiment, the laundry treating apparatus has a drying tunnel 4a for introducing a hot air flow into the laundry treating chamber 2a, specifically, the hot air flow in the drying tunnel 4a enters the laundry treating chamber 2a to dry the laundry in the laundry treating chamber 2a. It will be appreciated that in order to form a hot air flow, a heating element 41 and a fan 42 are arranged in the circulation duct 4, the heating element 41 being used to heat the air and the fan 42 being used to create a directional flow of air. The specific structure of the heating element 41 is not limited, and a resistance wire heating may be used, or a condenser in a heat pump system may be used as the heating element 41.
In one embodiment, the steam outlet 11b of the steam generator 11 communicates 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 by the secondary heating of the drying tunnel 4 a. On the one hand, when the clothes are dried by using the superheated steam, the problems of wrinkling, deformation and the like are not easy to occur due to the moist surface of the clothes and small drying stress, and moreover, the superheated steam drying belongs to no oxidation reaction, so that the clothes are not discolored, 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 a drying medium is negligible, so that the migration speed of moisture is high, and the time for drying clothes can be obviously reduced; in yet another aspect, the temperature of the superheated steam to dry the laundry is the boiling point temperature of water, thereby destroying bacteria and other toxic microorganisms on the laundry to achieve the effect of sterilizing the laundry.
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 force of the blower 42, is heated by the heating member 41 in the drying tunnel 4a, and then enters the laundry treatment chamber 2a, and the hot air flow in the laundry treatment chamber 2a is directly discharged to the atmosphere.
Illustratively, in one embodiment, the laundry treating apparatus includes a circulation duct 4 and a condensing device disposed on the circulation duct 4, the drying duct 4a is a part of the circulation duct 4, specifically, the drying duct 4a is located downstream of the circulation duct 4 in the airflow flowing direction, and the water inlet waterway 12 directs water flow to the condensing device to cool and dehumidify the airflow in the circulation duct 4. That is, in this embodiment, the air flow in the circulation duct 4 is cooled and dehumidified by water cooling, and the water inlet channel 12 provides 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.
A process of drying laundry by the laundry treatment apparatus: the hot dry air in the drying tunnel 4a enters the clothes treating cavity 2a, flows through the surface of wet clothes, performs heat-moisture exchange with the wet clothes, absorbs moisture in the clothes, changes into hot humid air flow, is discharged out of the clothes treating cavity 2a and enters the circulating air duct 4, passes through the condensing device, is cooled into low-temperature low-humidity air, enters the drying tunnel 4a, is heated into hot dry air, and enters the next cycle. The circulating operation realizes continuous and efficient drying of clothes.
It should be noted that, in an embodiment, water introduced into the condensing device by the water inlet waterway 12 may be in direct contact with the air flow in the circulating air duct 4, and the water and the air flow perform convective heat exchange to cool and dehumidify the air flow. In another embodiment, the water introduced into the condensing device by the water inlet channel 12 is not in direct contact with the air flow, the water cools the condensing device, and the air flow is cooled and dehumidified by heat exchange between the condensing device and the air.
Taking the direct contact of air flow and 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 and hot air flow is contacted with the condensed water to exchange heat, the condensed water absorbs heat in the wet and hot air flow, water vapor in the wet and hot air flow is separated out from the air flow due to cooling and is condensed into water drops, 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 and hot air flow is achieved, and the air flow is relatively low-temperature dry after being cooled and dehumidified by the condensing device.
In one embodiment, the water inlet channel 12 communicates with the laundry treating chamber 2a to supply washing water to the laundry treating chamber 2a, for example, referring to fig. 2, a water flow at an arrow on the right of fig. 2 flows to the laundry treating chamber 2a. For another example, referring to fig. 3, the water flow at the arrow under fig. 3 flows toward the laundry treating chamber 2a. It will be appreciated that a spray head may be provided at the end of the water inlet path 12, through which water is sprayed into the laundry treating chamber 2a. In this embodiment, as long as the laundry treatment apparatus washes laundry, water can be supplied to the water storage chamber 13a, and the water storage chamber 13a can be left in a state in which water is not absent for a long period of time.
In one embodiment, referring to fig. 1, a detergent box 19 is disposed on the water inlet channel 12, and water in the water inlet channel 12 flows through the detergent box 19 and then enters the laundry treating chamber 2a.

In one embodiment, the volume of the water storage chamber 13a is 1 to 6 times the amount of water required for the laundry treating apparatus in the single air washing mode. Specifically, the water amount required for the design required for the laundry treating apparatus to perform the primary air washing mode is V1, and the volume of the water storage chamber 13a is 1 to 6 times V1. That is, even in the case where the water storage chamber 13a is not half-way replenished with water, the water storage amount of the water storage chamber 13a can satisfy the air washing mode of the laundry treating apparatus for 1 to 6 times. .
Illustratively, the volume of the water storage chamber 13a is 3 to 6 times of the water amount required by the laundry treating apparatus in the single air washing mode, so that not only frequent water replenishment to the water storage chamber 13a can be avoided, the control operation is simplified, but also an excessively large installation space occupied by the excessively large volume of the water storage chamber 13a can be avoided.

That is, even if water is not supplied halfway, the water storage amount in the water storage chamber 13a can supply the laundry treating apparatus to perform the air washing mode for the preset number of times, and without exceeding the preset number of times, it is not necessary to separately supply water to the water storage chamber 13a. In this way, frequent water replenishment to the water storage chamber 13a can be avoided.
It should be noted that the preset number of times 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, and for example, the preset number of times may be 1 time, 2 times, 3 times, 4 times, 5 times, 6 times, and the like.
