Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

The embodiment of the application provides a wind heating device, and as shown in fig. 1, the wind heating device comprises a box body part 1, a fan 2, a heater 3 and a plurality of thermal protectors 4. The blower 2, the heater 3, and the plurality of thermal protectors 4 are located inside the box portion 1. The heater 3 has a plurality of heating portions 31. The positions of the thermal protectors 4 correspond to the positions of the heating portions 31, respectively, and the thermal protectors 4 are connected in series to the power supply line of the heater 3.

The box 1 is a combination of components of the air heating apparatus other than the fan 2, the heater 3, and the thermal protector 4.

The heater 3 is a heat source of the air heating apparatus. The heater 3 is located inside the air heating apparatus and opposite to the warm air opening, and in particular, may be fixed inside the heater fixing frame 10 of the box body portion 1. As shown in fig. 1, a grill 16 is further provided at the warm air outlet.

The thermal protector 4 is used for preventing the temperature of the heater 3 from being too high, and plays a role in ensuring the safety of the air heating equipment.

The positions of the plurality of thermal protectors 4 corresponding to the positions of the plurality of heating portions 31 respectively means that: at least one thermal protector 4 is provided at each heating portion 31. The number of the thermal protectors 4 may be greater than or equal to the number of the heating portions 31.

During the operation of the air heating apparatus, the respective heating portions 31 of the heaters 3 may have different temperatures, even widely different temperatures. And the air heating equipment that this application provided is through setting up at least one thermal protector 4 in every heating portion 31 department for no matter which heating portion 31's temperature is too high, thermal protector 4 can all in time respond to, switches the power supply line of heater 3, in time reduces the temperature of heater 3. Compared with the case that only one thermal protector 4 is arranged at the heater 3, the air heating device provided by the embodiment of the application does not respond to the situation that the local temperature of the heater 3 is too high due to the fact that the thermal protector 4 is too far away from the heating part 31.

A plurality of thermal protectors 4 can be connected in series in a power supply line of the heater 3, so that after one thermal protector 4 is disconnected, the whole heater 3 stops working, and the safety of the air heating equipment is improved. The specific manner in which the plurality of thermal protectors 4 are connected in series in the power supply line of the heater 3 may be as follows: the heating section 31 has a live terminal 311 and a neutral terminal 312. The live terminals 311 of the plurality of heating units 31 are connected to an external live line. The neutral wire terminals 312 of the plurality of heating portions 31 are each connected to one end of a thermal protector group, the other end of the thermal protector group being connected to an external neutral wire, the thermal protector group including a plurality of thermal protectors connected in series. (the specific connection is not shown in the figure).

Illustratively, the thermal protector 4 and the heating part 31 may be both two, and the heater 3 and the thermal protector 4 may be mounted as follows: the two heating units 31 are arranged side by side in the heater fixing frame 10 of the housing unit 1. The two thermal protectors 4 are respectively positioned outside the two heating portions 31 and are fixedly connected to the heater fixing frame 10. As shown in fig. 2, the thermal protector 4 is screwed to the frame wall.

The air heating device provided by the embodiment of the application can further comprise an environmental parameter sensor 5, wherein the environmental parameter sensor 5 is fixed on the panel 11 of the box body portion 1 and is electrically connected with the controller 12 of the box body portion 1. Therefore, the air heating equipment can automatically control the fan 2 and the heater 3 according to the data detected by the environmental parameter sensor 5.

In the following, a possible implementation form of the box portion 1 is provided, and a flow of automatic control of the air heating apparatus will be described with reference to the box portion 1:

the tank portion 1 may be divided into a panel portion and a lower case portion.

As shown in fig. 3a and 3b, the panel part includes a panel 11, a controller 12, a lamp panel 13 and a temperature display panel 14. The controller 12 and the environmental parameter sensor 5 are both fixed to the panel 11.

The panel 11 is a frame structure of the panel part, and plays a role of supporting the whole panel part.

The controller 12 is fixed on the panel 11, electrically connected to the environmental parameter sensor 5, and configured to receive data fed back by the environmental parameter sensor 5 and control the fan 2 and the heater 3 according to the fed-back data. The controller 12 may be in the form of a control circuit board.

The environmental parameter sensor 5 may be a temperature and humidity sensor, or may be one or two of a temperature sensor and a humidity sensor, and is configured to detect the temperature and/or the humidity of the environment, and the form of the environmental parameter sensor 5 may be as shown in fig. 5. In order to ensure the safety of the environmental parameter sensor 5, the environmental parameter sensor 5 may be fixed on the inner side of the panel 11, for example, may be fixed on the inner side of the panel 11 by screws. In order to make the environmental parameter sensor 5 sense the temperature and humidity of the external air more accurately, a through hole 111 may be formed in a portion of the panel 11 corresponding to the environmental parameter sensor 5. Also, a plurality of environmental parameter sensors 5, illustratively four, may be provided. A plurality of environmental parameter sensors 5 can be even respectively around lamp plate 13.

The lamp panel 13 can be an LED lamp panel for realizing the lighting function of the air heating device.

The temperature display panel 14 is used for displaying the temperature detected by the environmental parameter sensor 5. Optionally, the temperature display panel 14 may also be a temperature and humidity display panel for displaying the temperature and humidity detected by the environmental parameter sensor 5.

As shown in fig. 4, the lower case portion includes a lower case 15, a heater fixing frame 10, a grill 16, and the like. The fan 2 and the heater 3 are both located in the lower case 15. The fan 2 comprises a blowing wind wheel and a ventilation wind wheel.

The fan 2 can control the blowing wind wheel and the ventilation wind wheel according to an instruction sent by the controller 12. When the blowing wind wheel is opened, the hot wind function of the air heating equipment can be realized (the heater 3 is in an opening state), and when the ventilation wind wheel is opened, the ventilation function of the air heating equipment can be realized. The fan 2 may be of an existing fan structure.

The heater 3 can turn the heating function on and off according to a command from the controller 12.

The command from the controller 12 may be a wireless signal (such as a bluetooth signal or an infrared signal) or an electrical signal. Accordingly, the air heating apparatus has two structures:

first, the controller 12 is electrically connected to the fan 2 and the heater 3, respectively. In this case, the controller 12 may send out electric signals to control the fan 2 and the heater 3.

Second, the controller 12, the fan 2 and the heater 3 each have radio frequency components. In this case, the controller 12 may send out a wireless signal to control the fan 2 and the heater 3.

In the following, the flow of the automatic control of the air heating apparatus will be described in more detail by taking the example that the controller 12 sends a wireless signal to control the fan 2 and the heater 3:

when a user opens the hot air function of the air heating equipment, the environmental parameter sensors 5 start to work, and a plurality of (such as four) environmental parameter sensors 5 feed detected real-time data back to the controller 12, namely, temperature and humidity 1, temperature and humidity 2, temperature and humidity 3 and temperature and humidity 4.

The controller 12 calculates an average value of the received plurality of humiture values as a detected temperature and humidity value (including a detected temperature value and a detected humidity value). Also, the temperature display panel 14 may display the detected value of the humidity temperature in real time, or may display only the detected value of the temperature.

If the temperature detection value is higher than a first target temperature threshold (for example, 42 ℃), the controller 12 sends a first blowing wind wheel control signal to the fan 2, and the fan 2 reduces the rotating speed of the blowing wind wheel or closes the blowing wind wheel based on the first blowing wind wheel control signal. Meanwhile, the controller 12 may send a first heater control signal to the heater 3, and the heater 3 reduces the heating power or turns off based on the first heater control signal. If the temperature detection value is lower than a second target temperature threshold (for example, 25 °), the controller 12 sends a second blower wind wheel control signal to the blower 2, and the blower 2 starts the blower wind wheel or increases the rotation speed of the blower wind wheel based on the second blower wind wheel control signal. Meanwhile, the controller 12 may send a second heater control signal to the heater 3, and the heater 3 may boost heating power or start up based on the second heater control signal. Wherein the first target temperature threshold is larger than the second target temperature threshold, and the first target temperature threshold and the second target temperature threshold can be set by a user.

If the humidity detection value is higher than a first target humidity threshold value (for example, 98%), the controller 12 sends a first ventilation wind wheel control signal to the fan 2, and the fan 2 raises the rotation speed of the ventilation wind wheel or starts the ventilation wind wheel based on the first ventilation wind wheel control signal. If the humidity detection value is lower than a second target humidity threshold value (for example, 90%), the controller 12 sends a second ventilation wind wheel control signal to the fan 2, and the fan 2 reduces the rotation speed of the ventilation wind wheel or closes the ventilation wind wheel based on the second wind wheel control signal. Wherein the first target humidity threshold is greater than the second target humidity threshold, and the first target humidity threshold and the second target humidity threshold can be set by the user.

As can be seen, by providing the environmental parameter sensor 5, the controller 12 can control the fan 2 and the heater 3 based on the temperature and humidity detected by the environmental parameter sensor 5. Thereby realizing the automatic opening and closing of the hot air function of the air heating equipment. And when the user does not start the ventilation function of the air heating equipment, the ventilation function can be started in time, so that the phenomenon that the human body is lack of oxygen due to too much fog is avoided.

The above description is only exemplary of the present application and should not be taken as limiting, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
