- the pulsator 4 in the inner tub 3 of the washing and drying machine rotates, and the clothes in the inner tub 3 are stirred to be turned over, so that the laundry is in full contact with the high-temperature drying gas blown into the inner tub 3 to improve the clothes. Drying efficiency makes the clothes more uniform.
- the gas entering the air duct from the inner tub 3 is filtered through the filter screen 11 and then enters the heat pump system to prevent debris such as wire dust from entering the evaporator 10 or the condenser 9 of the heat pump system. Causes equipment failure.
- the temperature of the gas in the air circulation passage increases, and the heat contained in the medium in the heat pump system continuously increases, resulting in the condenser 9 and the evaporator 10.
- the temperature of the medium in the medium rises, causing the system pressure of the heat pump system to rise.
- it is necessary to reduce the working speed of the heat pump system by reducing the operating speed of the compressor 8 or other heat-dissipating protection mechanism through the frequency conversion control device to ensure stable and safe operation of the system.
- the compressor 8 when the surface temperature t1 of the condenser 9 is higher than the set value t l ' and/or the outlet pressure t2 of the compressor 8 is higher than the set value t2 ′ and/or the compressor 8 When the operating current I is greater than the set value , the operating speed of the compressor 8 drops to the set value. When the washing and drying machine starts to dry, the compressor operates at the initial rotation speed nl.
- the compressor rotation speed decreases from the initial rotation speed nl to n2; when the surface temperature t1 of the condenser 9 rises At t l2', the compressor speed drops from n2 to n3; when the surface temperature tl of the condenser 9 rises to t l3', the compressor speed drops from n3 to n4... until the compressor speed drops to the minimum speed n0
- the compressor runs at ⁇ speed until the end of drying.
- the compressor speed value is: n l>n2> n 3> n 4 ⁇ > n 0 ; the set value of the surface temperature of each condenser is: ⁇ 1 ⁇ ⁇ ⁇ 12 ⁇ ⁇ 13 ' ⁇ .
- the operating current I of the compressor 8 may be greater than the limit value Imax as the temperature in the barrel rises, and the condenser surface temperature reflecting the condensation temperature tl
- the compressor discharge temperature t2 above the limit value Umax and reflecting the internal temperature of the compressor is higher than the limit value t2max.
- the compressor 8 is stopped for a certain period of time T, and the condenser surface temperature t1 reflecting the condensation temperature and the compressor discharge temperature t2 reflecting the internal temperature of the compressor are lowered to the normal operating range.
- the compressor stop working time T is greater than or equal to 3 minutes.
- the operating current I of the compressor 8 is greater than the limit value Imax or the condenser surface temperature tl reflecting the condensing temperature is higher than the limit value Umax.
- the compressor discharge temperature t2 reflecting the internal temperature of the compressor is higher than the limit value t2max.
- the working pressure of the compressor 8 causes the operating current I of the compressor, the condenser surface temperature t1 reflecting the condensing temperature, and the compressor exhaust temperature t2 reflecting the internal temperature of the compressor to fall to the normal operating range.
- the compressor still does not return to the normal working state, and the compressor 8 is stopped for a certain time T.
- the T1 is greater than or equal to 3 minutes.
- the input electric energy of the driving compressor 8 is continuously transmitted by the medium, and is introduced into the circulating air path to heat the gas. Therefore, the heat loss in the entire circulation air path is only the energy consumption that is dissipated into the environment through the outer casing of the washing and drying machine, which reduces the energy loss of the entire system and improves the drying efficiency.
- the embodiments of the present invention may be further combined or substituted, and the embodiments are merely described for the preferred embodiments of the present invention, and are not intended to limit the scope and scope of the present invention. Various changes and modifications made by those skilled in the art to the technical solutions of the present invention are within the scope of the present invention.
