The existing dehumidifier with heating function adopts a tubular electric heater for heating, and a temperature control module is arranged in the dehumidifier for controlling the temperature of the electric heater. However, the tubular electric heater cannot automatically control the heating temperature, once the temperature control module in the device is damaged, the device cannot detect overhigh temperature and stop heating in time, a fire disaster is easily caused, and immeasurable fatal threat to the life and property safety of a user is brought.
To solve the above problems, in one embodiment, the variable frequency swimming pool dehumidifier 100 further comprises a PTC electrical heating element 90. The evaporator 70 is disposed obliquely in the air flow direction and opposite to the condenser 80, and the PTC electrical heating assembly 90 is disposed in the air chamber 10b and opposite to the condenser 80, and is electrically connected to the control module 110. The control module 110 is further configured to calculate a target temperature and control the PTC electrical heating assembly 90 to heat to the target temperature when receiving the ambient temperature signal sent by the ambient temperature sensor 20 and the ambient humidity signal sent by the ambient humidity sensor 30.
In the embodiment of the present invention, the inside of the casing 10 of the frequency conversion swimming pool dehumidifier 100 is divided into a left and a right two-chamber structure, wherein one side is a compressor chamber 10a, and the other side is a wind chamber 10 b.

In addition, an ambient temperature sensor 20 and an ambient humidity sensor 30 are disposed in the housing 10. The air from the swimming pool enters the air chamber 10b from the air inlet 11, and then flows out from the air outlet 12 through the fan 50, the evaporator 70, the condenser 80 and the PTC electric heating elements 90 in sequence.

In addition, the evaporator 70 is arranged obliquely, so that the contact area between the evaporator 70 and the air in the air cavity 10b is increased, and the evaporation efficiency is improved. Furthermore, the fan 50 includes a blade structure for forming a negative pressure in the air chamber 10b when rotating to suck the air of the swimming pool.
Referring to fig. 2, the environmental humidity sensor 30 is configured to collect the temperature of the environment around the variable frequency swimming pool dehumidifier 100 and send an environmental temperature signal to the control module 110; the environmental humidity sensor 30 is used for acquiring the humidity of the environment around the variable frequency swimming pool dehumidifier 100 and sending an environmental humidity signal to the control module 110. The frequency conversion module 60 is used to change the power supply frequency, thereby adjusting the load, and playing roles of reducing power consumption, reducing loss, prolonging the service life of the device, and the like.
In the actual operation process, the control module 110 receives the ambient temperature signal collected by the ambient humidity sensor 30 and the ambient humidity signal collected by the ambient humidity sensor 30, and calculates the target operation frequency and the target temperature according to the ambient temperature and the ambient humidity, respectively. Based on the fact that the target operation frequency has mathematical correspondence with the ambient temperature and the ambient humidity, the target operation frequency can be calculated according to the ambient temperature and the ambient humidity. In one embodiment, M ═ (N-RH/20 × (15-4.5) × (T)1) A, wherein M is target operation frequency, N is more than or equal to 230 and less than or equal to 300, RH is environment humidity, T1Is the ambient temperature and a is the deviation. Similarly, the target temperature and the ambient temperature have a mathematical correspondence, so the target temperature can be calculated according to the ambient temperature. In one embodiment, T ═ T1+ -. DELTA.T where T1At ambient temperature, Δ T is the heating temperature. After the target operating frequency and the target temperature are obtained, the control module 110 controls the frequency conversion module 60 to adjust the current power output frequency according to the target operating frequency, so that the operating power of the compressor 40 is changed, or the fan power is changedThe running power of the machine 51 is changed, or the running power of the machine and the running power of the machine are both changed, so that the displacement of the compressor 40 is adjusted, and the aim of adjusting the refrigerating capacity or the heating capacity of the dehumidifier is fulfilled. After the target temperature is obtained, the control module 110 controls the PTC electrical heating assembly 90 to heat to the target temperature. In addition, the frequency conversion swimming pool dehumidifier 100 adopts the frequency conversion technology to change the output frequency of the power supply, so that the compressor 40 and/or the fan motor 51 of the dehumidifier are/is automatically adjusted. Thus the fixed grid frequency can be changed to be adjustable and the size of the supply voltage can be expanded. Therefore, the frequency conversion swimming pool dehumidifier 100 in the embodiment of the invention is completely different from the traditional constant frequency dehumidifier, the frequency of the power supply is changed, the working efficiency can be improved by improving the frequency, the refrigerating capacity can be increased, and if the frequency is reduced, the output power can be reduced, and the refrigerating capacity can be reduced. The frequency conversion dehumidifier with advanced technology can be adjusted according to different use environments, thereby playing a role in the most reasonable power and having good energy-saving effect.
In summary, the frequency conversion swimming pool dehumidifier 100 in the embodiment of the present invention adopts a frequency conversion design, and can adjust the output frequency of the power supply, the operating power of the compressor 40 and/or the operating power of the fan motor 51 according to the conditions of the environment, such as humidity and temperature, etc., so as to make the compressor 40 and/or the fan motor 51 in an optimal operation state, thereby improving the working efficiency of the compressor 40 and/or the fan motor 51; meanwhile, when the target humidity or temperature value is reached, the variable frequency swimming pool dehumidifier 100 operates at a low frequency to maintain a constant humidity and temperature, and does not need to operate at a fixed high frequency from beginning to end like a constant frequency dehumidifier, so that the equipment is more energy-saving and environment-friendly. In addition, the tubular electric heater is replaced by the PTC electric heating assembly 90, automatic temperature control can be realized based on the PTC electric heating assembly 90, even if the PTC temperature sensor is damaged, and the control module 110 cannot control the PTC electric heating assembly 90 to stop heating, the PTC electric heater 92 can also automatically control the upper temperature limit, so that accidents such as fire disasters caused by unlimited heating of equipment are avoided, and the life and property safety of users is effectively guaranteed.
