Based on the above scheme, after the fan assembly is started, outside air is sucked into the fan cavity. After the air gets into the fan chamber, through heating assembly's heating, become hot air, heating assembly adjusts the temperature of air according to predetermineeing the temperature, hot air flows through the air supply channel under fan assembly's drive, air supply channel's design has guaranteed that hot air can high-efficiently transmit the next link, air supply channel's the other end links to each other with air duct 6, hot air passes through air duct 6 and gets into the wind chamber 4 that deposits that forms between sleeve 3 and the cylinder 2, wind chamber 4 is as a buffer zone, make hot air can evenly distributed, it gets into in the cylinder 2 through a plurality of fresh air inlets 202 on the cylinder 2 outer wall face to deposit the hot air in the wind chamber 4. Meanwhile, as the air inlets 201 are formed in the side face of the roller 2, hot air can directly enter the roller 2 through the air inlets 201, and the hot air exchanges heat with clothes in the roller 2 to take away moisture on the clothes, so that uniform and rapid drying of the clothes is realized, and the rotation of the roller 2 is conducive to more uniform heating of the clothes in the drying process. According to the application, the air is heated by the heating component, and the hot air is efficiently conveyed into the roller 2 by the fan component, so that the clothes are quickly dried, and the hot air can uniformly enter the roller 2 due to the design of the air inlet 201 on the side surface of the roller 2 and the plurality of air inlet holes 202 on the outer wall surface, so that the problems of local overheating or uneven drying of the clothes are avoided. In addition, the design of the wind storage cavity 4 enables hot air to be temporarily stored in the space, so that the hot air enters the roller 2 in a more uniform and rapid mode, waste of heat energy is reduced, and energy utilization efficiency is improved.

Preferably, the fan comprises a fan cavity, and the fan cavity is connected with the air supply channel. Under the drive of fan subassembly, outside air is inhaled the fan chamber at first, and at this moment, the air can pass through the filter screen that sets up in fan chamber and air supply channel hookup location, and the main effect of filter screen is blockked and filter impurity such as dust, hair, fibre in the air, ensures that the air that gets into the air supply channel is clean. After the filtering of the filter screen, clean air enters the fan cavity, is heated by the heating component and becomes hot air, then, the hot air flows through the air supply channel under the driving of the fan component, finally enters the air storage cavity 4 through the air conveying pipe 6, and then enters the clothes cavity from the air inlet 201 of the roller 2, so that uniform and rapid drying of clothes is realized. The filter screen can effectively block and filter the impurity in the air, ensures that the air entering the roller 2 is clean, can avoid the impurity to pollute the clothes, and can protect the fan component and the heating component and prolong the service life of the fan component and the heating component. Clean air can carry out the heat exchange with the clothing better, takes away the moisture on the clothing, improves the stoving effect, simultaneously, owing to avoided impurity to the influence of clothing, the clothing after the stoving is also cleaner, clean and tidier. In addition, through the filtration of filter screen, can reduce the impurity quantity that gets into the fan chamber, reduce fan subassembly and heating element's load to reduce the energy consumption. In addition, clean air can also reduce pollutant emission that produces in the stoving process, is favorable to the environmental protection.

It is worth mentioning that the filter screen is designed to be detachable, and convenience of customers regularly washs and changes, can keep the filter effect of filter screen like this, ensures drying equipment's normal operating. Meanwhile, equipment faults and maintenance cost caused by blockage of the filter screen are reduced.

Further, a door plate is hinged to the other side surface of the roller 2, an air outlet opposite to the air inlet 201 is formed in the door plate, and a return air pipe is connected between the air outlet and the fan cavity. During the drying process, as the drum 2 rotates, moisture and other gases in the laundry are carried out by the hot air and discharged through the air outlet of the drum 2, and the moisture-laden air is then re-sucked into the blower chamber through the return air duct. In the fan chamber, this air with moisture may be reheated or mixed with fresh air and then enter the drum 2 again through the supply air duct and the air duct 6, forming a circulating drying system. Through the setting of return air pipe, the air that has the moisture is inhaled the fan chamber again and perhaps heats again or mixes with fresh air, then gets into cylinder 2 again and dries, and this kind of circulation stoving's system can ensure that the hot air in the cylinder 2 keeps certain temperature and humidity all the time to improve drying efficiency, can effectively utilize the waste heat of return air to preheat newly inhaled fresh cold air moreover, reasonable effective utilization resource avoids the waste of resource.

Still further, the heating element includes the electric heat membrane, the electric heat membrane set up in the fan chamber with the hookup location of return air pipe. When the fan assembly is started, external air is sucked into the fan cavity after being filtered by the filter screen, and at the moment, the electrothermal film starts to work to heat the passing air, so that the passing air is changed into hot air. The electrothermal film directly converts electric energy into heat energy, does not consume oxygen and does not produce carbon dioxide, waste gas, waste water or waste emission, is a very environment-friendly heating mode, and compared with other heating modes, the electrothermal film heating system advocates the concept of saving in saving and can effectively reduce energy consumption. Moreover, the electrothermal conversion rate of the electrothermal film system is close to 100%, and compared with other heating systems, the electrothermal film system can save 10-15% of energy.

Optionally, a temperature sensor and a humidity sensor are disposed in the drum 2, the temperature sensor is electrically connected with the fan assembly and the heating assembly respectively, and the humidity sensor is electrically connected with the fan assembly and the heating assembly respectively. The temperature sensor can monitor the temperature in the roller 2 in real time and feed back the information to the control system, and the control system can automatically adjust the power of the heating component according to the set temperature range, so that the temperature in the roller 2 is ensured to be maintained in an ideal drying range. Meanwhile, the temperature sensor can be linked with the fan assembly, when the temperature in the roller 2 is too high, the control system can increase the rotating speed of the fan and improve the air flow, so that the temperature in the roller 2 is reduced rapidly, and the clothes are prevented from being overheated and damaged. Likewise, the humidity sensor can monitor the humidity level in the drum 2 in real time and transmit this information to the control system, which can adjust the operating states of the heating assembly and the blower assembly by comparing the set humidity target values, so as to realize accurate humidity control. When the humidity in the drum 2 is too high, the control system may increase the power of the heating assembly to raise the air temperature, thereby accelerating the drying process of the laundry. At the same time, the fan assembly may also increase the rotational speed, increase the air throughput, and help moisture to drain out of the drum 2 more quickly. Through intelligent temperature and humidity control, the system can avoid unnecessary energy waste, and when the temperature and the humidity in the roller 2 reach the set value, the system can automatically reduce the power of the heating assembly or close the fan assembly so as to save energy. In addition, accurate control can also reduce drying time, improves drying efficiency to further reduce the energy consumption.

Meanwhile, intelligent temperature and humidity control can ensure that clothes are heated and ventilated uniformly and moderately in the drying process, and local overheating or over-wetting of the clothes is avoided. This helps to improve the drying quality, making the garment softer, fluffy, and wrinkle-free.

In general, the air inlet holes 202 are distributed in an array on the outer wall of the drum 2, and the air inlet holes 202 are distributed in an array to ensure that a uniform air inlet amount can be obtained in each area inside the drum 2. In the drying process, the clothes continuously roll in the roller 2, if the air inlet is uneven, the uneven clothes drying can be possibly caused, the local overdry or overdry condition appears, and the air inlet holes 202 distributed in an array can well solve the problem, so that the clothes can obtain more uniform drying effect, the uniform air inlet can accelerate the circulation speed of air in the roller 2, and the moisture on the clothes can be more quickly taken away, so that the drying time can be shortened, the drying efficiency can be improved, and the energy consumption can be reduced. In addition, because the air inlet holes 202 are distributed in an array, the area of each air inlet hole 202 is relatively small, so that the flow speed and noise of air passing through can be reduced, vibration and noise caused by uneven air inlet can be reduced, and the use experience of a user is improved.

Further, the air intake of the air inlet 201 is more than 16 times of the air intake of the air inlet 202. The larger air inlet 201 can ensure that more hot air rapidly enters the inside of the drum 2, thereby accelerating the drying process of laundry. Compared with the air inlet holes 202, the air inlet 201 can provide higher air flow, the air inlet 201 is used as a main air inlet channel, the air is assisted to enter through the air inlet holes 202, hot air can be uniformly blown into the roller 2 at the fastest speed, the drying efficiency is effectively improved, and the drying effect of clothes can be guaranteed to be better.

Meanwhile, a clothes cavity is formed in the drum 2, and the air inlet volume of the air inlet 201 accounts for 2% -4% of the volume of the clothes cavity. The intake volume of the intake port 201 is 2% to 4% of the volume of the laundry cavity, which means that a proper amount of air can enter the laundry cavity to perform sufficient heat exchange with the laundry, which helps to maintain the air circulation inside the drum 2 and prevent the laundry from generating a moist and stuffy environment during the drying process. The proper air inlet volume can ensure that the clothes are supplied with enough hot air, so that the evaporation and discharge of water are quickened, the drying efficiency is improved, and the drying time is shortened. The proportion of the air inlet volume of the air inlet 201 to the volume of the clothes cavity is moderate, so that uniform heat distribution of each part of clothes can be ensured when the clothes roll in the roller 2, the local overdry or overdry condition of the clothes can be avoided, and the drying quality is improved.
