[0040] As attached Figure 7 Appendix Figure 11 and attached Figure 12As shown: energy-saving warm air blower 6 includes machine box 601, support ring 602, ceramic heater 603, fan 605 and second temperature sensor 606; support ring 602 is installed in machine box 601, ceramic heater 603 covers the side of support ring 602, and the side of ceramic heater 603 is provided with glass fiber insulation cotton 604, and fan 605 is installed at the end of support ring 602; second temperature sensor 606 is installed between ceramic heater 603 and glass fiber insulation cotton 604, and second temperature sensor 606 is located between the first and second heaters, and is formed at the air outlet, so that the air temperature of the air outlet can be stably measured, and the outer wall of machine box 601 is provided with control box 608; energy-saving warm air blower 6 uses ceramic heater 603 matched with glass fiber insulation cotton 604, which effectively reduces heat loss and improves heating efficiency.

[0041] As shown in the accompanying drawings Figure 6 As shown: the inner wall of drying room 3 is fixedly connected with fixed ring 401, first temperature sensor 4 is installed in fixed ring 401, fixed ring 401 is fixedly provided with fastening seat 402, and fastening seat 402 is threadedly connected with fastening bolt 403.

[0042] As shown in the accompanying drawings Figure 8 , the accompanying drawings Figure 13 and the accompanying drawings Figure 14 As shown: ceramic heater 603 is provided with assembly ring 607 around the side, assembly ring 607 is fixedly provided with fixed ring 401 around the side, second temperature sensor 606 is installed in fixed ring 401, and second temperature sensor 606 is located between ceramic heater 603 and glass fiber insulation cotton 604, and both ends of assembly ring 607 are fixedly provided with connecting plates 607a, and the two groups of connecting plates 607a are connected through bolts.

[0043] From the above, the heating process is as follows:

[0044] In the machine box 601 of energy-saving warm air blower 6, the side of support ring 602 is covered by ceramic heater 603, and the glass fiber insulation cotton 604 on the side effectively reduces the heat loss to the outside, so that the heat can be efficiently gathered. Fan 605 is installed at the end of support ring 602, and the heat generated by ceramic heater 603 is rapidly blown into drying room 3, so that the temperature in the room is rapidly increased.

[0045] Second temperature sensor 606 installed in support ring 602 monitors the internal temperature of the warm air blower in real time, and first temperature sensor 4 monitors the temperature in drying room 3 in real time. The data of the two temperature sensors will be transmitted to ceramic heater temperature controller t2 and indoor temperature controller t1 in the temperature control circuit module respectively, so as to ensure the stable operation of the warm air blower and avoid the influence of overheating and other abnormal conditions on the heating effect.

[0046] When the indoor temperature is lower than the starting temperature set by the indoor temperature controller t1 of the energy-saving fan heater and the starting temperature set by the temperature controller t2 of the ceramic heater, the temperature control circuit module works to control the ceramic heater 603 and the built-in fan M of the fan heater to be powered on and run through the contactor KM1 and the contactor KM2, the energy-saving fan heater 6 starts to run, the air blown by the fan 605 passes through the air heating passage of the ceramic heater 603, the air is heated, and the outlet blows warm air.

[0047] When the temperature measured by the second temperature sensor 606 reaches the stop temperature set by the temperature controller t2 of the ceramic heater 603, the temperature control circuit module acts to make the ceramic heater 603 stop heating by being powered off, but the fan 605 continues to work. Since the ceramic heater 603 has excellent heat preservation and heat storage functions, the air passing through the heating passage can still be heated, so the fan 605 can still blow warm air. When the temperature of the air heating passage decreases and the temperature measured by the second temperature sensor 606 is lower than the starting temperature set by the temperature controller t2 of the ceramic heater 603, the ceramic heater 603 is powered on and starts to run again, the temperature of the air heating passage rises, and the ceramic heater repeats the start-stop cycle.

[0048] Through test tests, when the starting temperature set by the temperature controller t2 of the ceramic heater is 70 degrees (starts when less than or equal to 70 degrees) and the stop temperature is set to 80 degrees (stops when greater than or equal to 80 degrees), the ceramic heater is powered on for 4 minutes and powered off for 3 minutes, and the outlet temperature is 70 degrees, so intermittent heating can save electricity. When the indoor temperature rises and the temperature measured by the first temperature sensor 4 reaches the stop temperature set by the indoor temperature controller t1, the ceramic heater 603 and the fan 605 are powered off and stop working; when the indoor temperature decreases and the temperature measured by the first temperature sensor 4 reaches the starting temperature set by the indoor temperature controller t1, the ceramic heater 603 and the fan 605 are powered on and start to run, and the fan heater repeats the start-stop cycle to save electricity.

[0049] The dehumidification process is as follows:

[0050] The humidity sensors 5 symmetrically distributed on the inner walls of both sides of the drying room 3 continuously and real-timely monitor the humidity conditions in the room, and these real-time data are immediately transmitted to the humidity controller (SK1 / SK2) in the electric control box 7.

[0051] When the device is set to the dehumidification mode, the humidity controller (SK1 / SK2) starts synchronously with the energy-saving fan heater 6. In this mode, the humidity controller (SK1 / SK2) works according to the pre-set starting humidity and stopping humidity values, and the starting humidity is greater than the stopping humidity. When the humidity in the drying room 3 is less than the starting humidity, the output contact of the humidity controller (SK1 / SK2) remains in the open state, and at this time, the exhaust fan M2 does not work and does not perform the exhaust operation.

[0052] With the drying process advances, if the drying room 3 chamber humidity gradually rises, reaches the starting humidity, the output contact of the humidity controller (SK1 / SK2) is closed quickly, this closing signal is transmitted to the humidity control circuit module, and the exhaust fan M2 is started to work through the contactor KM3 control, the exhaust is started, and the humidity in the room is gradually reduced. When the humidity decreases to the stop humidity, the output contact of the humidity controller SK1 / SK2 is disconnected again, and the exhaust fan M2 stops working, and the exhaust is no longer exhausted, and thus a complete dehumidification work cycle is completed.

[0053] In the dehumidification process, the circuit breaker QF4, the fuse FU4 and the overheat relay FR3 in the humidity main circuit module ensure the safety of power transmission of the high-power load of the exhaust fan M2 at all times, and effectively prevent overloading, short circuit and other faults of the circuit.

[0054] The device realizes high efficiency and energy saving through intermittent heating of the ceramic heater 603 and intelligent temperature control linkage. The ceramic heater 603 is covered with glass fiber insulation cotton 604 on the side, cooperates with the second temperature sensor 606 and the temperature controller t2, sets the 70 DEG C starting / 80 DEG C stopping threshold, so that the heater is powered off after working for 4 minutes, and the air outlet is still maintained at 70 DEG C for 3 minutes, which is 30% lower in power saving than traditional continuous heating. Meanwhile, the first temperature sensor 4 and the indoor temperature controller t1 are linked in real time, and when the drying room temperature reaches the standard, the ceramic heater 603 and the fan 605 are powered off, and the device stops running.

[0055] In the humidity control link, the device adopts the on-demand exhaust strategy to reduce power consumption; the humidity sensor 5 and the controller SK1 / SK2 set a gradient threshold, and the exhaust fan 1 is started only when the humidity is out of limit, and the running time is much lower than that of traditional equipment, reducing invalid operation; on the heat cycle structure, the support ring 602 forms a directional heating channel, cooperates with the fan forced convection, and the comprehensive power saving effect is remarkable.
