In some embodiments, the laundry treatment chamber 2a has a chamber wall without a drain channel. That is, there is no wash water in the laundry treating chamber 2a, and no drain is required, i.e., no injection of wash water into the laundry treating chamber 2a is required.

Note that, the drainless passage is for the wall of the laundry treatment chamber 2a, and does not refer to the whole laundry treatment apparatus. It is understood that the laundry treating apparatus as a whole may be provided with or without a drain pipe.

It is understood that the laundry treating apparatus as a whole may be provided with or without a drain pipe. For example, the laundry machine adopts a condensing type laundry drying method, and the laundry machine is provided with a drain pipe for discharging condensing water for condensing and cooling hot air flow. For another example, the laundry treatment apparatus adopts a heat pump type laundry drying method, and the laundry treatment apparatus may be provided with a drain pipe for draining condensed water or the like condensed and separated from the hot and humid air stream; the laundry treating apparatus may collect condensed water without a drain pipe.

Since the wall of the laundry treatment chamber 2a has no drain passage, the circumferential side wall of the laundry drum 2 is a continuous wall through which the fluid medium cannot pass, i.e., the laundry drum 2 is a hole-free inner drum. In the process of rotating the clothes containing cylinder 2, foam in the clothes containing cylinder 2 cannot directly penetrate through the clothes containing cylinder 2, so that the foam is prevented from flowing to the outside of the clothes containing cylinder 2, the foam can be effectively reserved in the clothes containing cylinder 2, and the cleaning effect of the foam on clothes is guaranteed.

The washing and drying integrated machine is as follows: has the functions of soaking and washing clothes in water and drying clothes.

In some embodiments, the laundry treatment apparatus employs an in-line dryer. The direct-discharge clothes drying mode refers to: the heating device is used for generating a dry hot air flow and sending the dry hot air flow into the clothes treatment cavity 2a, and the dry hot air flow is used for taking away moisture of clothes in the clothes treatment cavity 2a and directly discharging the moisture to the outside. Because foam cleaning is adopted, the utility model can greatly reduce water consumption under the condition that the cleaning capacity is approximately the same as that of water washing, is convenient for drying treatment after the foam cleaning treatment is finished, can save drying time and improve drying efficiency. After the clothes are cleaned, the clothes can be dried by utilizing air flow and the foams dissolved with the stains can be taken away, and the air flow discharges the water vapor and the foams dissolved with the stains to the outside, so that the effects of removing the foams and drying the clothes are achieved.

Illustratively, the laundry treating apparatus includes an air duct in communication with the laundry treating chamber 2a for providing an air flow to the laundry treating chamber 2a. It will be appreciated that the interior of the duct has heating means for heating the air flow. When the heating device heats, the air duct supplies a hot air flow into the laundry treating chamber 2a to dry laundry by the hot air flow. For example, after the foam is used for cleaning the clothes, the hot air flow is used for drying the clothes and taking away the solvent and the moisture in the foam, so that the effects of removing the foam and drying the clothes are achieved.

In some embodiments, the laundry treatment apparatus employs a condensing type laundry drying mode. Illustratively, the laundry treating apparatus includes a condensation dehumidifying member for condensing and dehumidifying the air flow discharged from the laundry treating chamber 2a. Specifically, the dry hot air flow in the air duct flows to the clothes treatment cavity 2a, and in the process of flowing through the clothes treatment cavity 2a, the dry hot air flow exchanges heat with clothes and takes away a part of water vapor to form wet hot air flow, the wet hot air flow is discharged out of the clothes treatment cavity 2a to be in contact with the condensation dehumidifying piece, and because the water vapor in the wet hot air flow is separated out due to temperature reduction, the air flow and the dry cold air flow after condensation dehumidifying through the condensation dehumidifying piece.

In some embodiments, the air flow discharged from the laundry treatment chamber 2a flows to the outside environment, i.e., the discharged air flow does not circulate into the laundry treatment chamber 2a. The air flow discharged from the clothes treating chamber 2a is condensed and dehumidified by the condensing and dehumidifying member, so that the air flow and the dry and cold air flow flowing to the external environment can reduce the influence on the humidity and the temperature of the external environment, and the pollution of impurities such as flocks and the like which are wrapped in the air flow to the external environment can also be reduced.

In other embodiments, two ends of the air duct are respectively communicated with the clothes treating cavity 2a. Thus, the air duct and the clothes treatment cavity 2a form a circulating air flow channel, and air flow can circulate in the clothes treatment cavity 2a and the air duct, so that on one hand, heat energy can be fully utilized, and on the other hand, adverse effects on the environment caused by direct discharge of the air flow to the external environment can be avoided.

The air duct is provided with a heating device and a condensation dehumidifying member, and the heating device is disposed downstream of the condensation dehumidifying member in the air flow direction, that is, the hot and humid air flowing out of the laundry treating chamber 2a flows through the condensation dehumidifying member and then through the heating device. The condensing and dehumidifying piece is used for condensing and dehumidifying the air flow, and the heating device is used for heating the air flow.

The working process and the clothes drying principle of the clothes treatment equipment of the embodiment are as follows: the dry and hot air flow enters the clothes treatment cavity 2a from the downstream of the air duct along the air flow direction, in the clothes treatment cavity 2a, the dry and hot air flow flows through the surface of wet clothes to perform heat-moisture exchange with the wet clothes to absorb moisture in the clothes, the wet and hot air flow enters the upstream of the air duct and sequentially flows through the condensation dehumidifying part and the heating device, in the process of flowing through the condensation dehumidifying part, water vapor in the wet and hot air flow is separated from the air flow due to temperature reduction and is condensed into water drops, the wet and hot air flow is condensed and dehumidified by the condensation dehumidifying part to form dry and cold air flow, the dry and cold air flow is heated into dry and hot air flow when passing through the heating device, and the dry and hot air flow enters the clothes treatment cavity 2a from the downstream of the air duct again, so that the circulation operation is realized, and continuous drying of the clothes is realized.

The dry and cold air flow is a flow of wet and hot air, and the temperature of the dry and cold air flow is lower than that of the wet and hot air flow. The low temperature in the embodiments of the present utility model may be room temperature.

The specific types of the condensation dehumidifying and heating apparatus described above are not limited.

For example, in some embodiments, the condensation dehumidifying element is a water-cooled condensation dehumidifying element, specifically, a condensation water channel is formed in the condensation dehumidifying element, the condensation dehumidifying element is connected with cooling water, the cooling water exchanges heat with the hot and humid air flow in the process of flowing through the condensation water channel, the cooling water absorbs heat of the hot and humid air flow, water vapor in the hot and humid 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 cooling water and finally discharged, and therefore, the effect of dehumidifying and cooling the hot and humid air flow is achieved. The heating means may be resistive heating.

In one embodiment, the laundry treatment apparatus comprises a heat exchange assembly for heat exchanging the air flow through the laundry treatment chamber 2a, at least part of the heat exchange assembly being located below the laundry drum 2. In this way, the heat exchange assembly makes the center of gravity of the laundry treating apparatus lower, so that the laundry treating apparatus is more stable.

The laundry treating apparatus may employ a heat pump type laundry drying mode, and in some embodiments, the heat exchange assembly includes a condenser and an evaporator, in which a refrigerant can circulate. The condenser and the evaporator are both disposed in the air duct through which the circulating air flow is supplied to the laundry treating chamber 2a. The refrigerant in the evaporator and the condenser exchanges heat with the air flow in the air duct to heat and condense the air flow. On the flow path of the air flow in the air duct, the air flow firstly flows through the evaporator and then flows through the condenser. Specifically, the evaporator is used for cooling and dehumidifying the hot and humid air flow from the clothes treatment chamber 2a to form dry and cold air flow, the condenser heats the dry and cold air flow into hot and dry air flow and then flows back into the clothes treatment chamber 2a, and the hot and dry air flow flowing back into the clothes treatment chamber 2a contacts with moist clothes to form the hot and humid air flow again, so that one drying cycle is completed. By repeatedly operating the drying cycle, the circulating air flow is continuously supplied to the laundry treating chamber 2a to dry the laundry.

In some embodiments, the laundry treatment apparatus further comprises a compressor and a throttling device, wherein the compressor, the condenser, the throttling device and the evaporator are sequentially connected in series through a pipeline to form a heat pump system, and the refrigerant can circulate in the heat pump system. The air flow in the air duct exchanges heat with the refrigerants in the evaporator and the condenser to form dry hot air flow.

The working principle of the heat pump system is as follows: the compressor sucks low-pressure gaseous refrigerant and compresses the refrigerant into high pressure and discharges the refrigerant; the discharged refrigerant in a high-pressure state enters a condenser, and the refrigerant in the condenser transfers heat to the air flow to be condensed into high-pressure liquid; the high-pressure liquid refrigerant is throttled and decompressed by a throttling device, and then becomes a low-pressure low-temperature gas-liquid two-phase mixture to enter an evaporator; the refrigerant in the evaporator absorbs the heat of the airflow and changes into a low-pressure gaseous state; the low-pressure gaseous refrigerant is sucked by the compressor again; and the circulation is repeated in this way, so that heat exchange is realized. That is, the evaporator is used for cooling and dehumidifying the hot and humid air flow from the clothes treating chamber 2a to form dry and cold air flow, the condenser heats the dry and cold air flow into hot and dry air flow and then flows back into the clothes treating chamber 2a, and the hot and dry air flow flowing back into the clothes treating chamber 2a contacts with the moist clothes to form the hot and humid air flow again, so that one drying cycle is completed. By repeatedly operating the drying cycle, the circulating air flow is continuously supplied to the laundry treating chamber 2a to dry the laundry.

By way of example, both the evaporator and the condenser may be fin-tube heat exchangers.

Illustratively, the restriction includes, but is not limited to, an expansion valve or a capillary tube, or the like.

In an embodiment, the laundry treatment apparatus comprises a wind wheel for driving an air flow between the laundry treatment chamber 2a and the air duct. Illustratively, the wind wheel is located in the wind tunnel. On the one hand, in the process of drying clothes, the wind wheel is used for driving air flow flowing through the clothes to sequentially flow through the evaporator and the condenser and then blow the air flow to the clothes to form circulating wind, so that the wind wheel can accelerate the air flow and improve the clothes drying efficiency. On the other hand, after the clothes are cleaned, the wind wheel can drive the airflow to flow, so that foams dissolved with stains and a small amount of water liquid on the clothes can enter the air duct along with the airflow, and the water vapor in the airflow and the foams dissolved with the stains are all condensed into liquid in the air duct.

In one embodiment, referring to fig. 2, the laundry treating apparatus includes a heat exchange case 9 below the laundry drum 2, and the compressor, the evaporator and the condenser are all located in the heat exchange case 9, and the evaporator is located upstream of the condenser in the flow direction of the air flow. The heat exchange shell 9 is part of an air duct. In the flow path of the air flow, the air flow passes through the evaporator and then through the condenser, for example, the evaporator is located at the front side of the condenser, and the wet cool air flow from the laundry treating chamber 2a passes through the evaporator and then through the condenser from the front side of the heat exchange case 9.

In one embodiment, referring to fig. 3, the electrical component 4 includes a main control board 41. The main control board 41 is used to control the start and stop of the laundry treating apparatus. That is, the main control board 41 may be used to control the operation of the whole machine, and to implement the automatic control of the laundry treating apparatus. For example, the main control board 41 may control the start and stop of the heating device, and so on.

In some embodiments, referring to fig. 3, the laundry treating apparatus includes a compressor, and the electric element 4 includes a first inverter board 42 electrically connected to the compressor, the first inverter board 42 being used to control a frequency of the compressor. Specifically, the compressor is used for sucking low-pressure gaseous refrigerant and compressing the refrigerant into high pressure for discharge, and the clothes treatment equipment adopts a heat pump type clothes drying mode.
