Description

Technical Field

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

[0002] With rising living standards, clothing made from mid- to high-end materials (such as real mink, imitation mink, cashmere, wool, leather, and down) is becoming increasingly commonplace in people's daily lives. Traditional washing methods for these materials can damage clothing, while dry cleaning cannot completely remove some stains and requires detergents and chemicals, making it inconvenient for people to clean at home.

[0003] To enable users to wash clothing made of the aforementioned materials at home, a clothing treatment device with an air wash program has been developed. Clothes are placed in the device's drum, and high-temperature, high-pressure gas is introduced into the drum as it rotates. This causes the fabric inside the drum to undergo airflow kneading, pressure-loss expansion, and softening, fully stretching the fibers and restoring their softness and elasticity. Simultaneously, strong air blows away lint and dust, achieving the effects of fluffing clothing, smoothing wrinkles, removing dust and odors, sterilizing and removing mites, and restoring the gloss of clothing. However, in this solution, the gas circulating in the clothing treatment device continuously absorbs surrounding water vapor, leading to an increase in humidity. Especially in the later stages of the air wash cycle, if the humidity of the gas introduced into the drum is too high, the clothing will not dry after washing, affecting the cleaning effect.

[0004] To address this issue, existing clothing treatment devices continuously introduce condensed water during the air wash cycle to cool the circulating air, thereby achieving dehumidification. For example, Chinese Patent Application No. 200610118766.5 discloses a method for washing clothes with air and a washing machine implementing this method. The washing machine includes a washing machine drum, a drainage pump, a heating and air supply system, and a condensing system. The heating and air supply system's air outlet opens into the washing machine drum, while the condensing system's opening for receiving hot air after washing communicates with the washing machine drum, with its outlet connected to the drainage pump. The condensing system includes a condensing drum. During operation, condensed water is continuously introduced and sprayed onto the inner wall of the condensing drum to cool it.

[0005] However, the dehumidification method using condensed water is not ideal for removing moisture from the circulating gas. At the same time, the continuous inflow of condensed water during the operation of the air washing process will consume a large amount of water resources and cause water waste.

[0006] In view of this, the present invention is proposed. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a control method for a clothing processing device, wherein the clothing processing device dehumidifies the circulating air through a heat pump module in an air washing program, has a good dehumidification effect, and saves water resources at the same time.

[0008] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0009] A control method for a clothes processing device, the clothes processing device comprising an inner drum and a heat pump module, the clothes processing device having an air washing program, during which the heat pump module is controlled to turn on to dehumidify the circulating air entering the inner drum.

[0010] Furthermore, the clothing processing device also includes an electric heating device. During the execution of the air washing program, the electric heating device is controlled to turn on and work in conjunction with the heat pump module to heat the circulating air entering the inner drum.

[0011] Furthermore, after the air washing program is started, the electric heating device is controlled to turn on to heat the circulating air entering the inner drum. After a certain period of time, the heat pump module is controlled to turn on to dehumidify the circulating air entering the inner drum and heat the air simultaneously with the electric heating device.

[0012] Preferably, the clothes treating apparatus further comprises a humidity sensor for detecting the humidity of the circulating air, and when the humidity detected by the humidity sensor is higher than a first preset humidity, the heat pump module is controlled to turn on.

[0013] Furthermore, the heat pump module is turned on and continues to work for a first preset time T1, and then the heat pump module is controlled to be turned off; or, when the humidity detected by the humidity sensor is lower than a second preset humidity, the heat pump module is controlled to be turned off;

[0014] After the heat pump module is turned off, the electric heating device remains on. When the electric heating device continues to work for a second preset time T2 after being turned on, the electric heating device is controlled to be turned off and the air washing program ends.

[0015] Preferably, the laundry processing device determines the second preset time T2 according to the material and / or weight information of the laundry in the inner drum.

[0016] Furthermore, after the air washing program is started, the electric heating device is controlled to turn on to heat the circulating air entering the inner drum. After a certain period of time, the electric heating device is controlled to turn off, and the heat pump module is controlled to turn on to dehumidify the circulating air entering the inner drum and heat the dehumidified air.

[0017] Furthermore, after the electric heating device is turned on and continues to work for a third preset time T3, the electric heating device is controlled to be turned off and the heat pump module is turned on;

[0018] Alternatively, the laundry processing device further comprises a temperature sensor for detecting the temperature of the circulating air, and when the temperature detected by the temperature sensor reaches a first preset temperature, the electric heating device is controlled to be turned off and the heat pump module is turned on;

[0019] Preferably, the laundry processing device determines the third preset time T3 or the first preset temperature according to the material and / or weight information of the laundry in the inner drum.

[0020] Furthermore, the heat pump module continues to work for a first preset time T1 after being turned on, and then controls the heat pump module to be turned off, and the air washing process ends;

[0021] Alternatively, the clothes treating apparatus further comprises a humidity sensor for detecting the humidity of the circulating air. When the humidity detected by the humidity sensor is lower than a second preset humidity, the heat pump module is controlled to be turned off and the air washing program ends.

[0022] Furthermore, the clothes processing device further comprises a spraying device capable of spraying water into the inner drum;

[0023] During the air washing process, the spray device is controlled to spray water into the inner drum for a certain period of time;

[0024] Preferably, the spraying device sprays water into the inner barrel in the form of a spray;

[0025] Preferably, the clothes treating device determines the water spraying time of the spraying device according to the material and / or weight information of the clothes in the inner drum.

[0026] Furthermore, the clothes processing device further comprises an electric heating device, and after the air washing program is started, the electric heating device is controlled to turn on to heat the circulating air entering the inner drum;

[0027] After the electric heating device is turned on, after a fourth preset time T4, the spray device is controlled to turn on;

[0028] Alternatively, the clothes treating device further comprises a temperature sensor for detecting the temperature of the circulating air, and when the temperature detected by the temperature sensor reaches a second preset temperature, the spraying device is controlled to turn on;

[0029] Preferably, the laundry processing device determines the fourth preset time T4 or the second preset temperature according to the material and / or weight information of the laundry in the inner drum.

[0030] Furthermore, after the clothes processing device is turned on, if a signal is received indicating that the user has selected an air wash program, the heat pump module is controlled to turn on during the operation of the clothes processing device to dehumidify the circulating air entering the inner drum.

[0031] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0032] During the air washing process, the clothes processing device of the present invention dehumidifies the circulating air through the heat pump module. Compared with the method of removing moisture by introducing condensed water in the prior art, it saves water resources and has a significant cooling effect on the circulating air, thereby having a better dehumidification effect.

[0033] In the air washing process, the clothes processing device of the present invention heats the circulating air through the cooperation of the electric heating device and the heat pump module, so that the temperature inside the inner drum can reach a higher level, thereby allowing the fibers of the clothes to fully stretch, achieving a better cleaning effect on the clothes, and at the same time increasing the elasticity of the clothes, making the fabric of the clothes softer.

[0034] During the air wash cycle, the clothes treatment device of the present invention controls the electric heating device and the heat pump module to heat the air simultaneously. This rapidly increases the temperature, quickly reaching the required washing temperature and shortening the air wash cycle. In contrast, a solution that first heats the air to the desired temperature using the electric heating device and then turns off the electric heating device and activates the heat pump module to simultaneously heat and dehumidify the air, resulting in a slower temperature increase, which can prevent damage to certain clothing materials caused by rapid heating.

[0035] A humidity sensor and / or temperature sensor is provided in the clothing processing device of the present invention, and the electric heating device and the heat pump module are controlled to be turned on or off according to the detected humidity and / or temperature, thereby more accurately controlling the temperature and humidity of the circulating air and achieving better clothing washing effects.

[0036] The laundry treatment device of the present invention sprays water into the inner drum during the air wash cycle. The sprayed water forms steam under the action of the high-temperature air, quickly soaking the clothes, thereby improving the cleaning effect and also providing a certain sterilization effect. Spraying water into the inner drum in the form of a spray can more quickly form water vapor, thereby more quickly and evenly soaking the clothes, further improving the cleaning effect.

[0037] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0043] 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.

[0044] Example 1

[0045] This embodiment provides a control method for a laundry processing device, wherein the laundry processing device includes an inner drum and a heat pump module. The laundry processing device of this embodiment has an air wash program. During the air wash program, the heat pump module is controlled to turn on to dehumidify the circulating air entering the inner drum.

[0046] In this embodiment, the clothing processing device dehumidifies the circulating air through the heat pump module during the air washing process. Compared with the method of removing moisture by introducing condensed water in the prior art, it saves water resources and has a significant cooling effect on the circulating air, thereby having a better dehumidification effect.

[0047] Furthermore, the clothing processing device of this embodiment also includes an electric heating device. During the execution of the air washing program, the electric heating device is controlled to turn on and cooperate with the heat pump module to heat the circulating air entering the inner drum.

[0048] In this embodiment, the circulating air is heated by the electric heating device and the heat pump module, so that the temperature inside the inner drum can reach a higher level, so that the fibers of the clothes can be fully stretched, the cleaning effect of the clothes can be better, and the elasticity of the clothes can be increased, making the fabric of the clothes softer.

[0049] Specifically, in this embodiment, the clothing processing device includes an air duct connected to the inner drum, in which a fan is installed. During the air wash process, the fan continuously operates, forming a circulating air between the air duct and the inner drum. The heat pump module includes an evaporator and a condenser. After the circulating air is drawn from the inner drum, it first passes through the evaporator along the air duct to be cooled, causing the water vapor therein to condense and separate from the circulating gas. The dehumidified circulating gas is then reheated by the condenser and then further heated by the electric heating device to produce hot, dry air, which then enters the inner drum to wash the clothes.

[0050] like Figure 1 As shown, in this embodiment, after the air washing program is started, the electric heating device is controlled to turn on to heat the circulating air entering the inner drum. After a certain period of time, the heat pump module is controlled to turn on to dehumidify the circulating air entering the inner drum and heat the air simultaneously with the electric heating device.

[0051] Preferably, the clothes treating apparatus further comprises a humidity sensor for detecting the humidity of the circulating air, and when the humidity detected by the humidity sensor is higher than a first preset humidity, the heat pump module is controlled to turn on.

[0052] In the above scheme, after the air wash process starts, the electric heating device is activated first to heat the circulating air, causing the circulating air temperature to rise at a faster rate, thereby quickly raising the temperature inside the inner drum. At the same time, during the initial stage of the air wash process, the humidity of the circulating air does not rise significantly, so the heat pump module can be turned off for dehumidification.

[0053] In this embodiment, a humidity sensor is provided to detect the humidity of the circulating air. When the humidity of the circulating air exceeds a first preset humidity, the heat pump module is activated to dehumidify the air, preventing further increases in humidity. This allows the humidity of the circulating air to be controlled within a certain range, preventing excessive humidity from affecting the washing effect. Simultaneously, the electric heating device and the heat pump module heat the circulating air, further accelerating the temperature rise, reaching the required washing temperature in a shorter time, and shortening the duration of the air wash process.

[0054] In a further solution of this embodiment, the heat pump module continues to work for a first preset time T1 after being turned on, and then is controlled to be turned off.

[0055] In another solution of this embodiment, when the humidity detected by the humidity sensor is lower than a second preset humidity, the heat pump module is controlled to be turned off.

[0056] After the heat pump module is turned off, the electric heating device remains on. When the electric heating device continues to work for a second preset time T2 after being turned on, the electric heating device is controlled to be turned off and the air washing program ends.

[0057] In this solution, the heat pump module is activated for a period of time during the air wash cycle to dehumidify the circulating air and simultaneously heat it with the electric heater. At the end of the air wash cycle, moisture from the clothing has been largely removed by the circulating air, and the humidity of the circulating air generally does not rise significantly. The heat pump module can be turned off to stop dehumidification. The electric heater remains on to maintain the circulating air temperature within a certain range until the air wash cycle ends.

[0058] In a preferred embodiment of this embodiment, the laundry processing device determines the second preset time T2 based on the material and / or weight information of the laundry in the inner drum. To achieve similar cleaning results for laundry of different materials or weights, different temperatures and cleaning times are required during air washing. The laundry processing device determines the operating time of the electric heating device based on the material and / or weight information of the laundry, thereby achieving good cleaning results for all laundry types during air washing in the laundry processing device.

[0059] In a further embodiment of this embodiment, the laundry treatment device further comprises a spraying device capable of spraying water into the inner drum. During the air wash process, the spraying device is controlled to spray water into the inner drum for a predetermined period of time. Preferably, the spraying device sprays water into the inner drum in the form of a mist.

[0060] In the above embodiment, the laundry treatment device sprays water into the inner drum during the air wash cycle. The sprayed water forms steam under the action of the high-temperature air, quickly soaking the clothes, thereby improving the cleaning effect and also having a certain sterilization effect. Spraying water into the inner drum in the form of a spray can more quickly form water vapor, thereby more quickly and evenly soaking the clothes, further improving the cleaning effect.

[0061] In this embodiment, the water spraying time of the spraying device can be a program setting value. For example, after the spraying device is turned on, it continues to spray water for 30 seconds, and then the spraying device is controlled to stop spraying water.

[0062] Preferably, the laundry processing device determines the spraying duration of the spraying device based on the material and / or weight of the laundry in the inner drum. When the laundry has good water absorption or the amount of laundry is large, the spraying duration of the spraying device is controlled to be longer, that is, the amount of water sprayed is increased, which can ensure that the laundry is fully soaked, thereby effectively improving the laundry cleaning effect.

[0063] Furthermore, after the air washing program is started, the electric heating device is first controlled to turn on to heat the circulating air entering the inner drum.

[0064] After the electric heating device is turned on, after a fourth preset time T4, the spraying device is controlled to turn on and spray water into the inner drum. Alternatively, the laundry processing device further includes a temperature sensor for detecting the temperature of the circulating air, and when the temperature detected by the temperature sensor reaches a second preset temperature, the spraying device is controlled to turn on and spray water into the inner drum.

[0065] In the above scheme, the electric heating device is first turned on to heat the circulating air. After the electric heating device has worked for a period of time, the spraying device is turned on to spray water into the inner drum to ensure that the inside of the inner drum has reached a relatively high temperature when the water spraying starts, and the sprayed water can quickly vaporize to form steam.

[0066] In this embodiment, the spraying device is controlled by a timer. After the air wash process is started, the electric heating device is first turned on to heat the circulating air. After 3 minutes, the spraying device is turned on to spray water into the inner drum in the form of a mist. The spraying device is controlled to stop spraying water for 30 seconds, and the subsequent steps of the air wash process are continued.

[0067] Preferably, the laundry processing device determines the fourth preset time T4 or the second preset temperature based on the material and / or weight of the laundry in the inner drum. The laundry processing device of this embodiment determines the timing for the spraying device to start spraying water based on the material and / or weight of the laundry, thereby ensuring that the sprayed water can be quickly vaporized in the inner drum, fully soaking the laundry and ensuring a good cleaning effect.

[0068] In a further solution of this embodiment, after the clothes processing device is turned on, if a signal is received that the user selects the air washing program, the heat pump module is controlled to turn on during the operation of the clothes processing device to dehumidify the circulating air entering the inner drum.

[0069] Specifically, the user puts the clothes into the inner drum and turns on the clothes processing device. The user can determine whether to run the air wash program according to the type of clothes. If the clothes are not washable, the user can operate the clothes processing device to select the air wash program and then start the clothes processing device to start running.

[0070] The clothing treatment device receives a signal indicating that the user has selected an air wash program, determines that the air wash program should be run, and then, upon receiving a start signal, turns on the fan to generate circulating air and simultaneously turns on the electric heater to heat the circulating air. After the electric heater is turned on for a period of time, the spray device is controlled to spray water into the inner drum in the form of a mist to fully wet the clothes. During the middle stage of the air wash program, the heat pump module is turned on and controlled to operate continuously for a period of time to dehumidify the circulating air and heat the circulating air simultaneously with the electric heater. After the heat pump module is turned off, the electric heater remains on until the air wash program ends, at which point the electric heater and fan are controlled to stop.

[0071] The clothing processing device of this embodiment can also execute a conventional washing program. If the clothing processing device receives a signal from the user selecting a conventional washing program, it opens the water inlet valve after receiving the start signal, fills water into the inner drum, and executes subsequent washing steps according to the set parameters.

[0072] In this embodiment, the clothing processing device has an air washing program, which cleans clothes that cannot be washed by water by passing high-temperature air into the inner drum. In the initial stage of the air washing program, water is sprayed into the inner drum in the form of a spray. The sprayed water quickly vaporizes to form steam under the high-temperature environment of the inner drum, evenly soaking the clothes, improving the cleaning effect of the clothes, and at the same time playing a certain sterilization role. The heat pump module is turned on for a period of time in the middle stage of the air washing program operation process to dehumidify the circulating air and heat the circulating air simultaneously with the electric heating device. The use of a heat pump module instead of the method of continuously passing condensed water for cooling and dehumidification in the prior art has a more significant cooling effect on the circulating air, thereby more effectively removing moisture from the circulating air and achieving a better cleaning effect for clothes by air washing. At the same time, since there is no need to continuously pass condensed water during the operation of the air washing program, water resources are saved.

[0073] Example 2

[0074] The difference between this embodiment and the above-mentioned embodiment 1 is that during the operation of the air washing program, the electric heating device is first turned off and then the heat pump module is turned on. The heat pump module dehumidifies the circulating air and independently heats the circulating air.

[0075] Specifically, if Figure 2 As shown, after the air washing program is started, the electric heating device is controlled to turn on to heat the circulating air entering the inner drum. After a certain period of time, the electric heating device is controlled to turn off, and the heat pump module is controlled to turn on to dehumidify the circulating air entering the inner drum and heat the dehumidified air.

[0076] In a further solution of this embodiment, after the electric heating device is turned on and continues to work for a third preset time T3, the electric heating device is controlled to be turned off and the heat pump module is turned on.

[0077] In another solution of this embodiment, the clothing processing device further includes a temperature sensor for detecting the temperature of the circulating air. When the temperature detected by the temperature sensor reaches a first preset temperature, the electric heating device is controlled to be turned off and the heat pump module is turned on.

[0078] In this solution, the heat pump module performs both heating and dehumidification functions. During the air wash cycle, the electric heater is activated first to heat the circulating air. After the heater has operated for a period of time, the temperature in the inner drum rises to a certain level. The heater is then deactivated, and the heat pump module is controlled to heat the circulating air alone. This maintains the circulating air temperature at a high level, ensuring a thorough cleaning of the clothes.

[0079] Compared to the first embodiment, this embodiment eliminates the need for simultaneous heating by the electric heating device and the heat pump module. The resulting temperature rise in the inner drum is slower, and the air wash cycle lasts longer. However, rapid heating can damage some clothing materials. This embodiment effectively protects clothing while achieving excellent cleaning results through air washing.

[0080] In a preferred embodiment of this embodiment, the laundry processing device determines the third preset time T3 or the first preset temperature based on the material and / or weight of the laundry in the inner drum. For laundry made of heat-resistant materials, the third preset time T3 can be set longer, or the first preset temperature can be set higher, to allow the laundry fibers to fully stretch during the air wash process, ensuring a thorough cleaning. When washing a large amount of laundry, the third preset time T3 or the first preset temperature can be appropriately increased to ensure that the laundry in the inner drum is fully heated.

[0081] Furthermore, the heat pump module continues to work for a first preset time T1 after being turned on, and then the heat pump module is controlled to be turned off, and the air washing program ends.

[0082] In another solution of this embodiment, the clothing processing device further includes a humidity sensor for detecting the humidity of the circulating air. When the humidity detected by the humidity sensor is lower than a second preset humidity, the heat pump module is controlled to be turned off and the air washing program ends.

[0083] In this solution, the heat pump module activates at the end of the air wash cycle to dehumidify the circulating air, which continuously removes moisture from the clothes and gradually dries them. The heat pump module also heats the dehumidified air, maintaining a high temperature for the clothes in the inner drum and ensuring a thorough cleaning. After the heat pump module has run for a while, the clothes in the inner drum are completely dry, completing the air wash process.

[0084] In this embodiment, when the laundry treatment device performs an air wash cycle, it first heats the circulating air to the desired temperature using an electric heating device. The electric heating device is then turned off, and the heat pump module is activated. The heat pump module simultaneously dehumidifies and heats the circulating air, removing moisture while maintaining the circulating air temperature. In this embodiment, the temperature rises relatively slowly within the inner drum. For clothing made of materials susceptible to rapid heating, this embodiment can effectively protect the clothing while achieving excellent cleaning results through air washing.

[0085] Example 3

[0086] like Figure 3 As shown, this embodiment provides a clothing processing device that utilizes the control method described in Embodiments 1 or 2 above, comprising an inner drum and an air duct connected to the inner drum, wherein a fan is disposed in the air duct. The air duct includes a rear air duct disposed outside the bottom of the inner drum, the rear air duct having an air outlet. An air inlet is disposed at the bottom of the inner drum, the air outlet being connected to the air inlet. The fan and electric heating device are both disposed in the rear air duct.

[0087] The air duct also includes an air supply duct connecting the tube opening of the inner tube and the rear air duct. Under the action of the fan, the air in the inner tube is drawn into the air supply duct through the tube opening of the inner tube, and then sent to the rear air duct, and then returns to the inner tube through the tube bottom of the inner tube.

[0088] The clothes treating device further includes a heat pump module, which includes an evaporator, a condenser, and a compressor. The evaporator and the condenser are arranged in the air supply duct.

[0089] In another solution of this embodiment, the evaporator and condenser can also be arranged on the peripheral side of the air supply duct to ensure that the evaporator can absorb heat from the air supply duct and the condenser can release heat to the air supply duct to heat the circulating air therein.

[0090] A filter module is also provided in the air supply duct, and the filter module includes a primary filter device and a secondary filter device.

[0091] In this embodiment, air drawn from the inner drum's opening passes through a primary filter and a secondary filter, removing lint from the circulating air. It then passes through the evaporator, where it absorbs heat and cools the air, condensing the water vapor and separating it from the circulating air, thus dehumidifying the air. The dehumidified air then passes through the condenser, where it absorbs heat and is reheated. It then flows into the rear air duct, where it is heated again by an electric heater before returning to the inner drum through the air inlet at the bottom of the inner drum.

[0092] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make slight changes or modifications to equivalent embodiments using the above technical content without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
