[0024] Furthermore, a main control box is installed on the right side of the main housing 13 , and the bottom surface of the main control box is open and is provided with a main control box cover 14 .

[0025] The working principle of the utility model is as follows:

[0026] In this design, the warm air conditioning box includes a main body box 13 and a main body upper cover 2 installed on the main body box 13; the corresponding diagonal ends of the main body box 13 and the main body upper cover 2 are cut to form a main body box cut angle surface and a main body upper cover cut angle surface; the main body box cut angle surface and the main body upper cover cut angle surface form a warm air conditioning box cut angle surface 11 of the shell.

[0027] One of the two corner ends of the warm air conditioner box in this design adopts the design structure of the warm air conditioner box cut angle surface 11; the strip air outlets 22 on both sides of the main unit upper cover plate 2 form two symmetrical warm air outlets; and the volute air duct 8 is installed in the middle of the inner bottom surface of the main unit box 13, and the DC variable frequency brushless motor 7 is installed in the middle of the volute air duct 8, and the DC variable frequency brushless motor 7 is installed with a centrifugal impeller 6, forming a "center-mounted wind wheel layout"; finally forming the structural feature of "extreme symmetrical aesthetics". That is, it includes the symmetrical cut angles of the warm air conditioner box and the symmetrical layout of the wind wheel on both sides of the warm air outlet.

[0028] In this design, the main unit size of the heating air conditioner box is 730mm×230mm×110mm (excluding the height of the air inlet protrusion).

[0029] The description of each component in this design is as follows:

[0030] (1) The extra-long poles on both sides of the wind wheel discharge air simultaneously, and the length of a single air outlet (strip air outlet 22) is 20 mm × 200 mm. The warm air covers a wider range, the air discharge is uniform and stable, and the body feels more comfortable.

[0031] (2) 24mm thick PTC heating block has a larger heat dissipation area, a longer air flow path, higher heating efficiency and better heating effect.

[0032] (3) Multiple levels of warm air speed can be designed, and a variety of different PTC heating power combinations can be matched to meet different heating needs.

[0033] (4) Multi-level ventilation function, the highest level: 230m3 / h maximum air volume, 210Pa maximum standard static pressure, the industry's top level.

[0034] (5) The main control box is equipped with a chip for driving the motor and a control mechanism for controlling the operation of the chip. The above chip and the PLC unit for controlling the operation of the chip are all existing technologies. When the ventilation function is used in various gears, the motor can automatically and steplessly adjust the speed to match the appropriate wind pressure according to the length of the air duct installed by the user, the installation conditions, the wind resistance and the air pressure in the public flue at the air outlet. Compared with the traditional AC constant speed motor, it can obtain a larger ventilation air volume.

[0035] (6) Warm air and ventilation can work at the same time. The cold / hot drying function can be turned on during the return of the south wind, the plum rain season, late autumn, cold winter and early spring.

[0036] (7) In this design, the DC variable frequency brushless motor 7 adopts a 24V low-voltage DC brushless motor, which has the advantages of ultra-low heat generation, temperature rise and noise, safety, reliability, and long service life.

[0037] (8) The chip configured for the motor drive has multiple active safety protections: overcurrent, overvoltage, undervoltage, stall, speed limit, etc., and automatically cuts off the motor power supply. The above functions are all existing technologies, so they are not elaborated in detail in this design.

[0038] 9. The PLC unit in the control panel can monitor the running status of the motor in real time. Once the speed is abnormal, the power supply of the host will be cut off immediately to avoid the risk of dry burning of the PTC heating block. The control circuit involved above is the existing technology.

[0039] The warm air in this design: the blowing / ventilation switch baffle is in the blowing state, and two PTCs (tentatively set at 1400W each) are heating at the same time. The motor speed is divided into 3 gears. At the highest gear, the outlet wind speed is 6.9m / s~8.3m / s (without panel).

[0040] Blowing in this design: The blowing / ventilation switch baffle is in the blowing state, and both PTCs are not working. The motor speed is divided into 3 gears. At the highest gear, the outlet wind speed is 7.3m / s~9.0m / s (without panel), and the control circuit involved is the existing technology.

[0041] In this design, the ventilation switch baffle is in the ventilation state, and both PTCs are not working. The motor works in three gears according to the PQ mode, and the above-mentioned electric control is the existing technology.

[0042] Cold drying in this design: blowing and ventilation at the same time, both PTCs are not working. The motor speed is only 1 gear.

[0043] The thermal drying in this design: blowing and ventilation at the same time, two PTCs heating at the same time. The motor speed is only 1 gear.

[0044] Wind direction in this design (if the panel has swing leaves): Control panel swing leaf stepper motor, adjust wind direction angle. Can swing or position at a certain angle.

[0045] Wind speed - / wind speed + in this design: When controlling each functional state, the motor working gear is reduced or increased. Cold / hot drying does not adjust the motor speed. The control circuit involved is the existing technology.

[0046] Lighting in this design: LED lighting. The lighting lamp can be installed in the light grooves on both sides of the mainframe upper cover 2 of the mainframe.

[0047] Standby in this design: turn off all functions except lighting. The control circuit here is treated as prior art. The above embodiments are only used to illustrate the technical solution of the utility model, not to limit it; although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that: it is still possible to modify the technical solutions recorded in the above embodiments, or to replace some of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the utility model.
