[0002] A washing machine is an indispensable household appliance in family life, providing convenience for daily life.

[0003] The working principle of the existing washing machine is to inject detergent and water into the washing drum, let the clothes soak in the detergent solution in the washing drum, and at the same time cooperate with the continuous rotation of the drum to wash the clothes through friction and / or beating.

[0004] However, detergents discharged with washing water will cause environmental pollution and lead to eutrophication of the discharged water. Long-term washing will also cause wear and tear on clothing fabrics, and mixing clothes of different shades and colors will cause the colors to blend with each other. In addition, a standard washing process of current washing machines is about one hour, which is a long time and has a poor user experience. At the same time, this will also aggravate the wear and tear of clothes. Moreover, a standard washing process includes at least one main wash and two rinses, which means that three water inlets are required, and the water consumption is also high.

[0005] In view of this, the present invention is proposed. Summary of the invention

DETAILED DESCRIPTION

[0063] 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.

Therefore, they cannot be understood as limitations on the present invention.

[0065] 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.

[0066] Figure 1 A partial structure of a clothes treating apparatus 100 provided according to an exemplary embodiment of the present invention is shown.

[0067] like Figure 1 As shown, the laundry processing apparatus 100 includes a drum assembly 110 , a water inlet assembly 120 , a freezing liquid delivery device 130 , and an ultrasonic wave generating device 140 .

[0068] The drum assembly 110 has a receiving chamber 114 for receiving the laundry. The water inlet assembly 120 is in communication with the receiving chamber 114 and is configured to introduce atomized water into the receiving chamber 114 to wet the fiber pores of the laundry. The freezing liquid delivery device 130 is in communication with the receiving chamber 114 and is configured to deliver a preset dose of freezing liquid into the receiving chamber 114 to freeze the water in the fiber pores of the laundry. The ultrasonic generator 140 is configured to emit ultrasonic waves into the receiving chamber 114 to break, peel off or remove the stains on the laundry.

[0069] Specifically, the inventor has found through research that, because the laundry is soft at room temperature, the energy of ultrasound is dispersed when it acts on the laundry, and it cannot achieve a satisfactory effect in removing stains. However, the cleaning effect on stains on hard solid objects is very good (the common ultrasonic cleaning of glasses in life and the ultrasonic removal of oil stains on workpieces in industry are typical applications of ultrasonic cleaning of hard solid stains). Based on this, the present invention uses atomized water to moisten the fiber pores of the laundry, and then uses a freezing liquid to freeze the water in the fiber pores of the laundry, and then uses ultrasound to break the ice in the fiber pores of the laundry to remove the stains on the laundry, thereby achieving the purpose of washing clothes without detergent, reducing wear and tear, better protecting the fabric of the clothes, and greatly saving water and washing time. .

[0070] It should be noted that the amount of water in the atomized state that is introduced into the accommodating chamber 114 by the water inlet assembly 120 of the present invention is very small, which is different from the conventional clothing processing device 100 that introduces water for soaking the laundry. The atomized water introduced into the accommodating chamber 114 of the present invention is only used to wet the fiber pores of the laundry. In other words, the laundry will not absorb a lot of water, so as to avoid the laundry becoming stiff and damaged when the laundry is subsequently frozen.

[0071] After the fiber pores of the laundry are moistened, the present invention uses the freezing liquid delivery device 130 to deliver a preset dose of freezing liquid into the accommodating chamber 114 to freeze the water in the fiber pores of the laundry. It should be noted that during the freezing process of the water in the fiber pores of the laundry, the laundry still appears to be soft as a whole, but only the fibers of the laundry are partially frozen, and the water is fixedly combined with the stains on the laundry. Then, ultrasonic high-frequency vibration is used to vibrate the laundry to break the ice in the fiber pores of the laundry, thereby peeling off the stains on the laundry and separating the stains from the laundry.

[0072] After the clothes to be washed are acted on by ultrasound for a period of time, the ice in the fiber pores of the clothes to be washed can be completely shattered, thereby being separated from the clothes to be washed. Thereafter, the ice can be melted by heating or natural temperature rise, and the ice can disintegrate some stains during the melting process. Then, water is added for rinsing. Since there is no detergent involved, the present invention only needs one rinse to clean the clothes, thus greatly saving time. Moreover, since the clothes are not washed by friction or falling, the wear and tear of the clothes will also be greatly reduced, so that the mixed washing of clothes of different colors will not cause color bleeding.

[0073] In some embodiments, the laundry processing device 100 further includes a housing 150, a door 152, and a sealing window gasket 153. The housing 150 has a laundry inlet 151 for putting laundry into the accommodating chamber 114. The door 152 is rotatably connected to the housing 150 and configured to open and close the laundry inlet 151. The sealing window gasket 153 is disposed at the laundry inlet 151 and is in contact with the door 152 when the door 152 closes the laundry inlet 151 to achieve sealing.

[0074] The barrel assembly 110 includes an outer barrel 112 and an inner barrel 111 rotatably disposed in the outer barrel 112. The barrel assembly 110 is flexibly suspended in the housing 150 by a suspension device, and the inner barrel 111 is connected to a driving unit 113 disposed at the rear of the outer barrel 112. The driving unit 113 is used to drive the inner barrel 111 to rotate in the outer barrel 112 at a preset speed.

[0075] The water inlet assembly 120 includes a water inlet pipeline 121 and a first atomizer 122. One end of the water inlet pipeline 121 is connected to a water source, and the other end is connected to the accommodating chamber 114. The first atomizer 122 is disposed on the water inlet pipeline 121 to atomize water entering the accommodating chamber 114.

[0076] As an example, the water inlet pipeline 121 is arranged at the top of the outer cylinder 112, and one end connected to the water source is connected to a solenoid valve, which can be used to control the on and off of the water inlet pipeline 121. The water source can be, for example, a faucet interface in a user's home.

[0077] In some embodiments, the water inlet pipeline 121 includes a main pipeline 1211, a first branch pipeline 1212, and a second branch pipeline 1213. One end of the main pipeline 1211 is connected to the water source; one end of the first branch pipeline 1212 is connected to the main pipeline 1211, and the other end is connected to the first atomizer 122; one end of the second branch pipeline 1213 is connected to the main pipeline 1211, and the other end is connected to the outer tube 112.

[0078] Specifically, the function of the first branch pipe 1212 is to guide the water of the water source to the first atomizer 122 to form water in an atomized state, and then guide the atomized water into the inner drum 111. The function of the second branch pipe 1213 is to guide the water of the water source to the outer drum 112 for rinsing the laundry. The first atomizer 122 includes at least one of a jet atomizer, an ultrasonic atomizer, and a vibrating mesh atomizer.

[0079] In some embodiments, the laundry treatment apparatus 100 further includes a drainage assembly 160. The drainage assembly 160 is in communication with the outer tub 112 and is used to drain the rinsing water in the outer tub 112 or the water generated during the laundry dehydration process.

[0080] The drainage assembly 160 can adopt a downward drainage method or an upward drainage method. When the drainage assembly 160 adopts an upward drainage method, the drainage assembly 160 includes a drainage pipeline 161 and a drainage pump 162 disposed on the drainage pipeline 161. Optionally, the drainage assembly 160 is disposed at the bottom of the outer cylinder 112.

[0081] In some embodiments, the freezing liquid delivery device 130 includes a freezing liquid storage box 131 and a quantitative delivery device 132. The freezing liquid storage box 131 is configured to store freezing liquid; one end of the quantitative delivery device 132 is connected to the outlet of the freezing liquid storage box 131, and the other end is connected to the receiving chamber 114, and the quantitative delivery device 132 is configured to control the dosage of freezing liquid delivered into the receiving chamber 114. As an example, the freezing liquid is liquefied air, liquid oxygen or liquid nitrogen. Preferably, liquid nitrogen has the characteristics of high cold density, low price, environmental protection and safety. Selecting liquid nitrogen as the freezing liquid can reduce the use cost of the clothing processing device 100 provided by the present invention. Compared with other common freezing liquids, liquid nitrogen has a high cold density, can make water freeze quickly, and the ice crystals generated when freezing quickly are small, will not damage clothing fibers, and is conducive to protecting clothing.

[0082] The quantitative dispenser 132 may adopt a vacuum pump such as a venturi tube, or a metering pump suitable for liquid nitrogen, which will not be described in detail in the present invention.

[0083] It is understandable that in order to avoid the loss of coldness of the refrigerant, the quantitative dispenser 132 is connected to the refrigerant storage box 131 and the quantitative dispenser 132 is connected to the accommodating chamber 114 by an insulation pipeline 134. The insulation pipeline 134 is made of, for example, foaming material or insulation cotton to prevent the loss of coldness.

[0084] In some embodiments, the refrigerant delivery device 130 further includes a diluter 133, which is disposed on a delivery pipeline between the quantitative delivery device 132 and the accommodating chamber 114, and the diluter 133 is configured to dilute the refrigerant delivered into the accommodating chamber 114 with a safe gas such as air.

[0085] In some embodiments, the refrigerant delivery device 130 further includes a second atomizer disposed on the delivery pipeline between the quantitative delivery device 132 and the accommodating chamber 114 to atomize the refrigerant entering the accommodating chamber 114 .

[0086] Specifically, the control unit of the clothing processing device 100 determines the required amount of liquid nitrogen according to the weight and / or type of the laundry, and then determines the volume and temperature of the required dilution air according to the amount of liquid nitrogen. The control unit then sends an instruction to the quantitative dispenser 132. The quantitative dispenser 132 extracts a specific amount of liquid nitrogen from the freezing liquid storage box 131 according to the received instruction and transmits it to the diluter 133 through the insulation pipeline 134. The diluter 133 dilutes the liquid nitrogen by adding a specific volume and a specific temperature of air, and then converts it into cold air with a moderate temperature and then dispenses it into the inner drum 111. In this way, the laundry can be quickly slightly frozen, avoiding a stream of liquid nitrogen directly sprayed on the laundry to freeze the clothes and damage the clothes when the inner drum 111 rotates.

[0087] In addition, when the atomized freezing liquid is delivered, the second atomizer can be used to directly atomize the liquid nitrogen and blow it into the inner drum 111. The contact area between the atomized liquid nitrogen and the air increases rapidly, quickly absorbing the heat in the air, lowering the ambient temperature and vaporizing itself. During the rotation of the clothes driven by the inner drum 111, the ambient temperature is evenly lowered to a slightly frozen state of the clothes.

[0088] In some embodiments, the outlet ends of the water inlet assembly 120 and the refrigerant delivery device 130 are respectively connected to the accommodating chamber 114 through the sealing window gasket 153. The above scheme introduces the atomized water and the diluted refrigerant directly into the inner drum 111 for holding clothes through the sealing window gasket 153, which can improve the wetting effect of the fiber pores of the clothes to be washed, and improve the effect of freezing the water in the fiber pores of the clothes to be washed.

[0089] In some embodiments, the clothing processing apparatus 100 further includes a heating device, which is disposed on the drum assembly 110, and may be, for example, an electromagnetic heating device, which heats the rotating inner drum 111 through the outer drum 112, and is configured to increase the ambient temperature within the drum assembly 110, so as to melt or sublime the ice within the drum assembly 110.

[0090] In some embodiments, one or more ultrasonic generators 140 may be provided according to the actual needs of the laundry processing apparatus 100. As an example, the ultrasonic generator 140 is provided on the side of the door 152 facing the inner drum 111, and is used to emit ultrasonic waves of specific energy to the slightly frozen laundry in the inner drum 111.

[0091] Figure 2 A flow chart of a control method 200 of a laundry treating apparatus 100 according to an exemplary embodiment of the present invention is shown.

[0092] like Figure 2 As shown, the execution of the control method 200 of the laundry treatment device 100 includes the following steps:

[0093] S210, in response to obtaining the laundry information of the laundry to be washed, calling the washing parameters corresponding to the laundry information according to the laundry information, wherein the washing parameters at least include the water intake, the freezing liquid dosage, the preset speed and the preset time;

[0094] S220, controlling the water inlet assembly to feed water into the accommodating chamber to wet the fiber pores of the laundry;

[0095] S230, in response to determining that the amount of water flowing into the accommodating chamber reaches the water inflow amount, controlling the freezing liquid delivery device to deliver freezing liquid into the accommodating chamber so as to freeze water in the fiber pores of the laundry;

[0096] S240, in response to determining that the amount of the refrigerant added into the accommodating chamber reaches the refrigerant addition amount, controlling the inner cylinder of the cylinder assembly to rotate at the preset speed;

[0097] S250: In response to determining that the time for which the inner drum of the drum assembly rotates at the preset speed reaches the preset time, controlling the ultrasonic generating device to start emitting ultrasonic waves into the accommodating chamber, so as to break ice in the fiber pores of the laundry and remove the stains on the laundry.

[0098] It should be understood that the steps shown in the control method 200 of the clothing processing device 100 are not exclusive, and the control method 200 of the clothing processing device 100 may also include additional steps not shown and / or may omit the steps shown, and the scope of the present invention is not limited in this respect. It should be noted that the embodiments of the present invention and the features in the embodiments may be combined with each other in the absence of conflict. In addition, unless explicitly limited or inconsistent with the context, the specific steps included in the method described in the present invention are not necessarily limited to the order described, but may be executed in any order or in parallel. Refer to the following Figure 1 and Figure 2 Steps S210 to S250 are described in detail.

[0099] Specifically, when the user uses the clothes processing device 100 to wash clothes, the user opens the door 152 of the clothes processing device 100, puts the clothes into the inner drum 111, and then starts the washing process after closing the door 152.

[0100] In step S210, the control unit of the clothing processing device 100 can obtain clothing information such as the weight of the laundry, clothing material, etc. using sensor systems such as RFID tag information, weight sensors, and image sensors. The control unit retrieves the washing parameters corresponding to the clothing information from the database pre-stored in the control unit based on the acquired clothing information. The washing parameters include at least the amount of water intake, the amount of refrigerant added, the preset speed, and the preset time. In addition, after retrieving the amount of refrigerant added, the control unit can also retrieve the volume and temperature of the dilution air corresponding to the amount of refrigerant added. It should be pointed out here that the correspondence between clothing information and washing parameters is obtained after a large number of experimental verifications, and the correspondence is set and stored in the control unit when the clothing processing device 100 leaves the factory.

[0101] In step S220, the control unit sends a control instruction to the water inlet assembly 120, so that the water inlet assembly 120 feeds water into the accommodating chamber 114, thereby wetting the fiber pores of the laundry. In some embodiments, during the water inlet process, the control unit also sends a control instruction to the driving unit 113, so that the driving unit 113 drives the inner drum 111 to rotate slowly at a preset speed to ensure that the fiber pores of the laundry absorb water uniformly.

[0102] In step S230, the control unit uses a flow meter or a mist timer to determine that when the amount of water flowing into the accommodating chamber 114 reaches the water inflow amount, controls the first atomizer 122 to stop spraying water mist into the inner drum 111, and sends a control instruction to the freezing liquid delivery device 130 to control the freezing liquid delivery device 130 to deliver freezing liquid into the accommodating chamber 114 to freeze the water in the fiber pores of the laundry. In this step, the control unit of the clothing processing device 100 sends an instruction to the quantitative dispenser 132. The quantitative dispenser 132 extracts a specific amount of liquid nitrogen from the freezing liquid storage box 131 according to the received instruction and transmits it to the diluter 133 through the insulation pipeline 134. The diluter 133 adds a specific volume of air at a specific temperature to the liquid nitrogen for dilution, and then converts it into cold air with a moderate temperature and then dispenses it into the inner drum 111. In this way, the clothes to be washed can be quickly slightly frozen, avoiding a stream of liquid nitrogen directly sprayed on the clothes to be washed to freeze the clothes and damage the clothes when the inner drum 111 rotates.

[0103] In step S240, the control unit uses the quantitative dispenser 132 to determine that the dosage of the refrigerant added to the accommodating chamber 114 reaches the refrigerant dosage, and sends a control instruction to control the quantitative dispenser 132 to be disconnected. In addition, the control unit may also send a control instruction to the driving unit 113 so that the driving unit 113 drives the inner drum 111 to rotate slowly at a preset speed to ensure that the environment in the inner drum 111 is evenly cooled and the water in the fiber pores of the laundry is completely frozen. It should be noted that during the process of adding the refrigerant, the rotation speed of the inner drum 111 is very low, which is different from the conventional laundry processing device 100 that uses rotation to beat the laundry to clean the laundry.

[0104] In step S250, the control unit of the clothing processing device 100 uses a timer to determine that when the time for the inner drum 111 of the drum assembly 110 to rotate at the preset speed reaches the preset time, the control unit controls the ultrasonic generating device 140 to start emitting ultrasonic waves into the accommodating chamber 114, so as to break the ice in the fiber pores of the laundry to be washed and remove the stains on the laundry.

[0105] In some embodiments, the execution of the control method 200 of the laundry treatment device 100 includes the following steps:

[0106] S260, in response to determining that the start time of the ultrasonic generator 140 reaches the set time, controlling the ultrasonic generator 140 to be turned off, and controlling the heating device of the laundry processing device 100 to be started to melt or sublimate the ice in the cylinder assembly 110;

[0107] S270: In response to determining that the ice in the drum assembly 110 has melted or sublimated, control the water inlet assembly 120 to feed water into the drum assembly 110 to rinse and dehydrate the laundry.

[0108] Specifically, in step S260, the ambient temperature in the drum assembly 110 is raised or a certain period of time is waited to melt the ice in a small portion of the laundry that is not covered by the ultrasonic generator. When the ice melts or sublimates, the stains condensed with it are peeled off. In step S270, when it is determined that the ice in the drum assembly 110 has melted or sublimated, the water inlet assembly 120 is controlled to feed water into the drum assembly 110, and the laundry is rinsed, dehydrated, and drained in sequence.

[0109] At this point, the cleaning of the laundry is completed. It can be seen that in the process of using the clothing processing device 100 of the present invention to wash the laundry, there is no involvement of detergent, the liquid nitrogen evaporates naturally without residue, it is non-toxic and harmless, and the process is environmentally friendly. And only one rinse is required, so it will greatly save time, and also save water and electricity. Compared with the standard program of a traditional washing machine, the water consumption is saved by at least 66% (a standard program of a traditional washing machine consists of a main wash stage and at least two rinse stages, including 3 water intakes, and the amount of water required for atomization of the washing machine of the present invention is negligible, that is, only one water intake is required). Due to the extremely small wear and tear, the risk of color bleeding when light and dark clothes are mixed is also reduced. And because the clothes are not washed by friction or falling, the inner drum 111 only needs to be rotated gently, which can effectively prevent the clothes from being worn.
