In some embodiments, the amount of exhaust from the exhaust assembly 4 is not less than the amount of air entering the cleaning chamber 11 from the outside while the exhaust assembly 4 is in operation.

It should be noted that, in actual use, the cleaning chamber 11 cannot be completely sealed, a small amount of gas exchange exists between the cleaning chamber 11 and the outside, and in the case that the exhaust amount of the exhaust assembly 4 is not less than the amount of gas entering the cleaning chamber 11 from the outside, the cleaning chamber 11 is in a normal pressure or negative pressure environment, and the drying rate is improved in the negative pressure environment.

In this embodiment, when only the exhaust assembly 4 works, the cleaning chamber 11 is pumped into a negative pressure state by the exhaust assembly 4 due to lack of sufficient supplement of external air, and the drying rate is improved correspondingly under the negative pressure environment.

When the internal circulation assembly 2 and the exhaust assembly 4 work simultaneously, the fan 22 can circulate the air in the cleaning chamber 11, so that the temperature and the humidity in the cleaning chamber 11 are uniformly distributed, and the effect of uniform drying of the whole chamber is further improved.

In some embodiments, as shown in fig. 1 and 5, the air duct 21 includes an air compensating branch 213, an air compensating inlet 2131 of the air compensating branch 213 communicates with the outside, an air compensating outlet of the air compensating branch 213 communicates with the cleaning chamber 11, and an exhaust air amount of the exhaust air assembly 4 is not less than an air compensating amount of the air compensating branch 213 under the condition that the exhaust air assembly 4 and the blower 22 are operated.

By providing the air make-up branch 213, an outer circulation and/or an inner circulation of the cleaning chamber 11 can be achieved to achieve various modes of operation of the cleaning device.

In the working process of only the fan 22, in order to maintain the balance of the pressure in the cavity of the cleaning cavity 11, the fan 22 only sucks the air in the cleaning cavity 11 as much as possible to realize basic internal circulation, and the air quantity of the internal circulation is far greater than that of the external circulation at the moment, so that the effect of rapidly improving the temperature and the humidity in the cleaning cavity 11 can be achieved; when the fan 22 and the exhaust assembly 4 work simultaneously, the exhaust assembly 4 extracts and discharges air in the cleaning chamber 11, at the moment, the fan 22 mainly introduces external air, a small amount of air in the cavity is sucked for circulation, at the moment, the internal and external circulation is performed simultaneously, and the rapid dehumidification requirement of the dehumidification stage can be effectively improved.

Under the condition that the air exhaust assembly 4 and the fan 22 work, the air exhaust amount of the air exhaust assembly 4 is not less than the air supplementing amount of the air supplementing branch 213, that is, the cleaning chamber 11 is pumped into normal pressure or negative pressure by the air exhaust assembly 4 when the air exhaust assembly 4 is opened, in other words, the cleaning chamber 11 is normal pressure or negative pressure when the air supplementing branch 213 supplements air, and the cleaning chamber 11 is negative pressure when the air supplementing branch 213 does not supplement air.

In the related art, the single internal circulation scheme is helpful to circularly heat the gas to be dried in the cleaning chamber 11 and reach a proper temperature, but the single internal circulation scheme also needs the exhaust assembly 4 to gradually exhaust the evaporated water vapor, and in the exhaust stage, the exhaust assembly 4 can gradually pump the cleaning chamber 11 into negative pressure due to lack of external gas, so that the exhaust rate is gradually reduced, and the overall moisture removal rate of the cleaning device is not well improved.

According to the application, by arranging the air supplementing branch 213, the air pressure balance in the cleaning chamber 11 can be maintained through the air supplementing branch 213 when the air exhaust assembly 4 works, and the vacuum degree in the cleaning chamber 11 is reduced, so that a higher exhaust rate can be maintained, the water vapor in the cleaning chamber 11 can be rapidly exhausted, the overall moisture removal rate and the drying rate of the cleaning equipment are improved, and the energy consumption of hot air drying is further reduced.

For example, if the air inlet 211 of the air duct 21 is disposed on the top wall 12 of the cleaning chamber 11, the grille 2156 can properly guide the hot air to the direction below the cleaning chamber 11, so as to prolong the flow path of the hot air in the cleaning chamber 11, increase the area of the air heated by the heater 23 flowing through the whole cleaning chamber 11, and improve the effects of full-cavity drying and dead-corner drying of the cleaning chamber 11.

For example, if the exhaust assembly 4 is positioned at the upper left side of the cleaning chamber 11, the grille 2156 can properly guide the hot air to the direction below the rear side of the cleaning chamber 11, so that the flow path of the hot air in the cleaning chamber 11 can be prolonged, the area of the air heated by the heater 23 flowing through the whole cleaning chamber 11 can be increased, the effects of full-cavity drying and dead-angle drying of the cleaning chamber 11 can be improved, the air volume discharged by the exhaust assembly 4 without being utilized can be reduced, and the utilization efficiency of the heat energy of the hot air can be increased.

When the temperature and humidity in the cleaning chamber 11 are too low, forced convection and cyclic heating in the cleaning chamber 11 can be realized by turning on the blower 22 and the heater 23, so that evaporation of the water remaining in the cleaning chamber 22 is accelerated.

Secondly, the cleaning equipment has a dehumidifying negative pressure working mode;

in the dehumidifying negative pressure operation mode, the fan 22 and the heater 23 are stopped, and the air exhaust assembly 4 works.
