Detailed ways

In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

As shown in FIG. 1 , this embodiment provides a clothes dryer, which includes a housing 1 and a drum 2 rotatably arranged in the housing 1 . An air passage is formed between the housing 1 and the drum 2, and a heater (not shown) and a fan (not shown) are arranged between the housing 1 and the drum 2, and the drum 2 is provided with an air inlet and The air outlet, the air inlet and the air outlet communicate with the air duct. After the heater works, the air in the housing 1 is heated, and the hot air circulates into the drum 2 to heat the clothes through the action of the fan, so as to achieve the purpose of drying clothes.

In order to make the clothes dryer have a better wrinkle removal function, the clothes dryer also includes a spray structure. The spray structure includes a shower head 32, a water pipe 31 and a water inlet valve 33. The water inlet valve 33 can be arranged on the housing 1. One end of the water pipe 31 is connected with the water inlet valve 33, and the other end is connected with the shower head 32. The shower head 32 can extend into the drum 2 so as to spray water mist into the drum 2 . During the ironing process of the clothes, the sprayed water mist is converted into high-temperature water vapor under the action of the heater, and the high-temperature water vapor fully contacts the clothes, which can achieve the ironing and wrinkle-removing effect on the clothes.

The wrinkle removal effect of a single spray on the clothes is not obvious. Therefore, the clothes dryer is also provided with a control assembly and a temperature sensor. The temperature sensor can be arranged in the drum 2, and the control assembly is electrically connected to the temperature sensor. The clothes dryer can perform multiple sprays during the wrinkle removal process, and by detecting the temperature rise in the drum 2 before and after spraying, the number of sprays can be determined to obtain a better wrinkle removal effect.

In order to adjust the flow rate and duration of spraying water mist according to the weight of the clothes, there can be a weighing module and a timing module in the clothes dryer. There are multiple sets of spray duration and water mist flow values in the control module, and each group of spray duration and water mist flow rate Values correspond to a range of laundry weights. Both the weighing module and the timing module are electrically connected to the control assembly. When the clothes dryer starts to work, the weighing module weighs the weight of the clothes and sends it to the control component. On-off and the opening of the water inlet valve 33 are large or small to control the time of spraying and the flow of water mist in the drum 2, so as to obtain a better wrinkle removal effect.

The control component can also include a control template, which is provided with a spray time adjustment button and a water mist flow adjustment button, which can be used to adjust the spray duration and flow according to the folds of the clothes and the demand.

As shown in FIG. 2 , this embodiment also provides a control method for a clothes dryer. After the clothes dryer works, the heater heats the air in the drum 2, and as the heating time prolongs, the temperature in the drum 2 gradually increases. By monitoring the temperature in the drum 2, when the temperature in the drum 2 rises to the specified temperature, the spray assembly can be activated to spray water mist into the drum 2. After the water mist contacts the clothes, a high temperature will be formed under the action of the heater Steam iron to remove wrinkles. Wherein, the specified temperature may be 125-135°C.

After the clothes have been sprayed once, the temperature in the drum 2 is detected at a specified time interval. If the temperature difference between the temperature in the drum 2 and the specified temperature is greater than the preset temperature rise value stored in the control component, the water mist in the drum 2 is fully heated and evaporated. , then the wrinkle removal of the clothes is completed, the heater can stop working, and the clothes in the drum 2 can be taken out after the clothes are cooled. If the temperature rise before and after spraying in drum 2 is less than the preset temperature rise value, the water mist in drum 2 is not fully heated and evaporated, and the effect of removing wrinkles on clothes is poor. At this time, it is necessary to repeatedly spray into drum 2 until it is detected If the temperature rise before and after spraying is greater than the preset temperature rise value, the heater can stop working. Wherein, the preset temperature rise value in the program can be 10-20.

In order to ensure that the clothes have a good wrinkle-removing effect, the clothes dryer should spray into the drum 2 at least twice during the process of removing wrinkles from the clothes.

In order to ensure that the water vapor produced by the evaporation of the water mist can fully contact the clothes in the drum 2, thereby improving the wrinkle removal effect, the duration of spraying into the drum 2 and the flow rate of the sprayed water mist can be set according to the weight of the clothes in the drum 2 . Specifically, the weight of the clothes is divided into multiple intervals in the control component, and the spray duration and the water mist flow value are correspondingly stored in each interval. When clothes are put into the dryer, by weighing the weight of the clothes, the control unit automatically selects the spray duration and water mist flow value of the corresponding interval, so as to meet the wrinkle removal needs of clothes of different weights.

In this embodiment, the time of spraying in the drum 2 can be 1.5-2min each time, and the corresponding spray flow rate can be 60-80mL/min, and the specified time between the completion of each spraying and the detection of the temperature rise in the drum 2 can be It is 9-12min.

As the number of sprays increases, the temperature in the drum 2 gradually increases, and the corresponding spraying time in the drum 2 can be extended successively, so as to prevent the water mist from being heated as high-temperature steam before it fully contacts with the clothes and discharged from the drum 2.

At the same time, as the number of sprays increases, the temperature in the drum 2 gradually increases, which will also cause the temperature in the drum 2 to rise rapidly after the spraying is completed. In order to ensure that each spray has a good wrinkle removal effect, the specified time interval after each spray is completed can be shortened successively, so as to ensure accurate temperature rise comparison.

The above content is only a preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation and application scope. limits.
