[0065] Reference Figures 1 to 8 As shown, the blower heater provided in the embodiment of the present invention includes a shell 10 and a panel 20 covering the shell 10. The shell 10 and the panel 20 form a receiving cavity 11. The receiving cavity 11 is provided with a controller 18 and a blower assembly and a heating assembly 14 electrically connected to the controller 18.

[0066] The panel 20 is provided with an air inlet 24 and an air outlet 25 which are in communication with the accommodating cavity 11 .

[0067] The fan assembly includes a ventilation fan 12 and a heating fan 13 . The outlet of the ventilation fan 12 is connected to the outside, and the outlet of the heating fan 13 faces the heating assembly 14 .

[0068] The airflow entering the accommodating chamber 11 through the air inlet 24 flows to the outside driven by the ventilation fan 12 and / or flows to the heating component 14 driven by the heating fan 13 , and flows out of the accommodating chamber 11 through the air outlet 25 .

[0069] It should be noted that the housing 10 of the fan heater provided in this embodiment may have a housing cavity 11, and the housing 10 may be square, circular or irregular in shape. The panel 20 covers the opening of the housing cavity 11 of the housing 10 to form a closed environment in the housing cavity 11. The panel 20 is provided with an air inlet 24 and an air outlet 25, and the closed environment of the housing cavity 11 may be connected to the outside through the air inlet 24 and the air outlet 25. The shapes of the housing 10 and the panel 20 may be set according to actual needs, as long as the two are in a mutually matching state, and this embodiment does not limit this, nor is it limited to the above examples.

[0070] When in use, the blower heater is installed in the indoor ceiling, wherein the shell 10 is located between the ceiling panel 20 and the roof, and the panel 20 leaks out of the ceiling panel 20 to expose the air inlet 24 and the air outlet 25. The air inlet 24 and the air outlet 25 are used to realize the process of indoor gas entering and exiting the accommodating cavity 11.

[0071] Among them, the panel 20 provided in this embodiment may include a first cover body 21 and a second cover body 22 that are interlocked with each other, the first cover body 21 covers the cavity opening of the accommodating cavity 11, and a mounting cavity 23 connected to the accommodating cavity 11 is formed between the first cover body 21 and the second cover body 22, and an air inlet 24 and an air outlet 25 connected to the mounting cavity 23 are opened on the second cover body 22. As an optional embodiment, the air inlet 24 and the air outlet 25 are respectively located on opposite sides of the geometric center of the second cover body 22. In this way, it is possible to effectively avoid the inlet airflow of the air inlet 24 and the outlet airflow of the air outlet 25 from interfering with each other, affecting the normal air intake and outlet processes. And a stable gas circulation process can be formed between the accommodating cavity 11 and / or the mounting cavity 23 and the indoor room to ensure the normal and stable use of the heater.

[0072] Reference Figure 3 and Figure 4 As shown, the installation cavity 23 and the accommodating cavity 11 are connected through a connecting port 26, wherein a plurality of connecting ports 26 may be provided, and a plurality of connecting ports 26 are arranged at intervals between the installation cavity 23 and the accommodating cavity 11. This embodiment does not limit the number of connecting ports 26 and the interval distance between adjacent connecting ports 26, and can be adjusted according to actual needs. A filter 28 is provided on the side of the connecting port 26 close to the installation cavity 23, which is used to filter the gas entering the heater. On the one hand, it can prevent the concentration of harmful substances in the indoor gas from being too high or the volume from being too large, thereby damaging the various components inside the heater and protecting the heater; on the other hand, the heater can be used to filter and purify the indoor gas, thereby ensuring the cleanliness of the indoor gas. The filter 28 can be at least one layer of filter mesh, filter cotton or filter membrane, etc. This embodiment does not limit this, nor is it limited to the above examples.

[0073] Furthermore, a mounting guide 29 and a mounting frame are provided on the filter 28. The mounting guide 29 has a guide surface facing the connecting port 26. The mounting frame is located between the mounting guide 29 and the connecting port 26. A preset mounting area for the filter 28 is formed inside the mounting frame, and one end of the guide surface abuts against the mounting frame. Since the filter 28 needs to be replaced regularly and the blower heater is located at the ceiling position indoors, in order to reduce the difficulty of replacing the filter 28, when installing the filter 28, the end of the filter 28 can be abutted against the guide surface of the mounting guide 29 and slid along the guide surface to reach the preset mounting area of ​​the mounting frame, thereby effectively reducing the difficulty of replacing the filter 28 and improving the convenience of using the blower heater.

[0074] Reference Figure 6As shown, the heating fan 13, ventilation fan 12, heating component 14 and controller 18 provided in this embodiment are all arranged in the accommodating cavity 11 of the shell 10. The controller 18 is electrically connected to the heating fan 13, ventilation fan 12 and heating component 14 for controlling the working states of the three, thereby realizing different working modes of the heater.

[0075] It should be noted that the blower heater provided in this embodiment may include three working modes when working, namely, drying mode, heating mode and ventilation mode. When the blower heater works in ventilation mode, the controller 18 controls the ventilation fan 12 to turn on and the heating fan 13 to turn off. When the ventilation fan 12 is working, it can guide the indoor air to enter the installation cavity 23 through the air inlet 24, and then enter the accommodating cavity 11 through the connecting port 26, and then flow to the outdoors through the ventilation channel 15 connected to the outlet of the ventilation fan 12. The indoor gas replacement can be completed by continuously working according to the above-mentioned gas flow process, forming the indoor and outdoor gas circulation of the blower heater.

[0076] When the heater is in heating mode, the controller 18 controls the heating fan 13 to turn on and the ventilation fan 12 to turn off. When the heating fan 13 is working, it can guide the indoor air to enter the installation cavity 23 through the air inlet 24, and then enter the accommodating cavity 11 through the connecting port 26, and then guide it through the heating component 14 through the heating fan 13, and then flow out from the air outlet 25 and enter the room again. The heat of the airflow flowing through the heating component 14 is increased, so after multiple gas cycles, the temperature of the indoor gas is increased to achieve the heating effect. The above process also forms the indoor and outdoor gas circulation of the heater.

[0077] When the heater adopts the dry mode, the controller 18 controls the heating fan 13 and the ventilation fan 12 to start at the same time. When the two are working, they can guide the indoor air to enter the installation cavity 23 through the air inlet 24, and then enter the accommodating cavity 11 through the connecting port 26. Part of the air entering the accommodating cavity 11 is taken to the outside by the ventilation fan 12 through the ventilation channel 15, and the other part of the air entering the accommodating cavity 11 is guided to the position of the heating component 14 by the heating fan, and after being heated by the heating component 14, it flows out from the air outlet 25 and enters the room again. Therefore, after the above-mentioned cycle process, not only can the indoor air be replaced, but also the indoor air can be heated to keep it warm and dry.

[0078] In actual use, the user can adjust the above three working modes according to actual needs, and this embodiment does not limit this.

[0079] Reference Figure 2 and Figure 4As shown, the blower heater also includes a ventilation channel 15 , and an air outlet 25 of the ventilation fan 12 is connected to the outside through the ventilation channel 15 .

[0080] It should be noted that the ventilation fan 12 provided in this embodiment can be connected to the outdoors through the ventilation duct 15. When installed, the ventilation duct 15 can be located between the ceiling panel 20 and the roof. The connection point between the ventilation duct 15 and the ventilation fan 12 can be located on the side wall of the shell 10, thereby effectively utilizing the side wall space of the shell 10 and improving its space utilization rate.

[0081] A heating chamber 16 is provided on one side of the accommodating chamber 11 close to the air outlet 25 , an inlet of the heating chamber 16 is connected to an outlet of the heating fan, and an outlet of the heating chamber 16 faces the air outlet 25 .

[0082] It should be noted that in order to ensure the heating effect of the heating component 14 on the gas, a heating chamber 16 can be set on the side of the accommodating chamber 11 close to the air outlet 25. The heating component 14 is used to heat the gas in the heating chamber 16, and the air outlet 25 is used to discharge the gas back into the room to achieve the heating effect.

[0083] It should be pointed out that the side of the accommodating chamber 11 close to the air outlet 25 can effectively reduce the flow path of the heated gas to the air outlet 25, thereby reducing the heat consumed by the gas flowing in the accommodating chamber 11 to ensure that the warm air can be used to increase the temperature of the indoor environment as much as possible.

[0084] The heating component 14 may be located in the heating chamber 16 and / or at the outlet of the heating chamber 16. The present embodiment does not limit the specific location and manner of the heating component 14. As an optional embodiment, the heating component 14 may include any one or more of a heating wire, a heating sheet, a heating net, and a heating tube. The present embodiment does not limit this.

[0085] Furthermore, the blower heater also includes an air guide plate 17 , which is disposed between the outlet of the heating chamber 16 and the air outlet 25 . The airflow heated by the heating component 14 flows to the air outlet 25 under the guidance of the air guide plate 17 .

[0086] Reference Figure 6 As shown, in the accommodating cavity 11 provided in the present embodiment, an air guide plate 17 is further provided at the outlet position of the heating cavity 16, and the air guide plate 17 is connected to a driving device (not shown in the figure). The driving device can drive the air guide plate 17 to rotate and adjust the extension direction of the air guide plate 17, so as to change the flow direction of the heated airflow by utilizing the air guide plate 17, guide the heated airflow to the position of the air outlet 25, and reduce the flow path and flow time of the warm air in the accommodating cavity 11.

[0087] As an optional implementation, the heating fan 13 and the ventilation fan 12 are both centrifugal fans. Both can be centrifugal fans, that is, the air inlet direction is the axial direction of the fan, and the air outlet direction is along the peripheral direction of the fan.

[0088] As a feasible implementation manner, an audio device 30 is arranged on one side of the installation cavity 23 close to the air inlet 24. The audio device 30 includes a sound producing member 31 and a sound guide cover 32 arranged on the sound producing member 31. At least one sound guide channel 321 is opened on the sound guide cover 32. One end of the sound guide channel 321 faces the sound producing member 31, and the other end of the sound guide channel 321 faces the air inlet 24.

[0089] The sound guide cover 32 is arc-shaped, and the concave side of the arc-shaped sound guide cover 32 faces the air inlet 24 .

[0090] It should be noted that an audio device 30 can also be provided on the blower heater provided in this embodiment, so that music can be enjoyed while heating and ventilating. This can not only enrich the function of the blower heater, but also improve the integration of the blower heater and the audio device 30, which is in line with the current design concept of integrated homes.

[0091] The sound device 30 can be arranged in the installation cavity 23 near the air inlet 24. Of course, in actual use, the sound device 30 can also be arranged on the side of the air outlet 25. This embodiment takes the sound device 30 arranged on the side of the air inlet 24 as an example for description and drawing. Figures 1 to 3 ,as well as Figure 8 As shown, the sounding member 31 in the audio device 30 can be an electronic speaker. The sounding member 31 is electrically connected to the controller 18 and emits sound under the control of the controller 18. The sound output direction of the sounding member 31 can be set toward the air inlet 24, so that the sound can be emitted from the installation cavity 23. A sound guide cover 32 can be set in the sound output direction of the sounding member 31. The sound guide cover 32 can be arc-shaped, and the concave side of the arc-shaped sound guide cover 32 faces the air inlet 24. In this way, the sound guide cover 32 can be used to form a sound amplification structure, which amplifies the sound to a certain extent and facilitates the conduction of sound waves.

[0092] Among them, an inclined mounting support 311 can also be set at the bottom of the sound piece 31, and the mounting support 311 has a mounting surface, which faces the side of the air inlet 24, so as to ensure that when the sound piece 31 is set on the mounting support 311, its sound output direction faces the air inlet 24.

[0093] A plurality of intervally arranged sound guide channels 321 may also be provided on the sound guide cover 32, one end of the sound guide channel 321 faces the sounding member 31 to collect more sound waves, and the other end faces the air inlet 24 to facilitate the sound waves in the sound guide channel 321 to be transmitted from the air inlet 24 to the outside of the installation cavity 23. The shape of the cross section of the sound guide channel 321 may be circular, square, triangular or irregular, and in actual use, it may be designed as required, and this embodiment is not limited thereto, nor is it limited to the above examples.

[0094] As a feasible implementation, a movable door panel 27 is provided on the air outlet 25, and a guide portion 271 is opened on the inner wall of the installation cavity 23, one end of the guide portion 271 is located at the air outlet 25, and the other end of the guide portion 271 extends in a direction away from the air outlet 25.

[0095] At least part of the end of the moving door panel 27 is clamped in the guide portion 271 , and a traction assembly 272 connected to the moving door panel 27 is provided in the installation cavity 23 . The moving door panel 27 slides back and forth along the extension direction of the guide portion 271 driven by the traction assembly 272 .

[0096] When the fan heater is working, the traction assembly 272 drives the moving door panel 27 to separate from the air outlet 25, so that the installation cavity 23 is connected to the outside.

[0097] It should be noted that the air outlet 25 provided in this embodiment is also provided with a moving door plate 27, which can prevent external dust, impurities or mosquitoes from entering the installation cavity 23 or the accommodating cavity 11 inside the heater when the heater is not working, thereby protecting the heater. The moving door plate 27 can be installed in a guide portion 271 inside the installation cavity 23, and the guide portion 271 can be a guide groove or a guide rail. The guide portion 271 can be located on two opposite inner side walls inside the installation cavity 23, so that the opposite ends of the moving door plate 27 are respectively clamped in the guide portion 271.

[0098] One end of the guide portion 271 is located at the air outlet 25, and the other end extends in a direction away from the air outlet 25. Figure 3 and Figure 4As shown, the extension direction of the guide portion 271 can be inclined, that is, one end is located on one side of the air outlet 25, and the other end can not only extend toward a position away from the air outlet 25, but also be inclined toward a side close to the center of the installation cavity 23, so that when the moving door panel 27 slides along the guide portion 271, it can be tilted and slid to a position away from the air outlet 25, and is located at the bottom of the second cover body 22. The second cover body 22 is used to shield the moving door panel 27, so that when the heater is working, the user cannot see the moving door panel 27 from the surface of the second cover body 22, which not only can prevent the moving door panel 27 from affecting the air flow of the air outlet 25, but also can ensure the aesthetic appearance of the heater.

[0099] The traction assembly 272 may include a driving motor electrically connected to the controller 18, a driving gear connected to the output shaft of the driving motor, and a driven rack meshing with the driving gear, and the moving door plate 27 is connected to the driven rack; the extension direction of the driven rack is the same as the extension direction of the guide portion 271. When the heater is working, the controller 18 controls the driving motor to work, the driving motor drives the driving gear to rotate, the driving gear drives the driven rack and the moving door plate 27 to slide in a direction away from the air outlet 25, and the moving door plate 27 slides along the extension direction of the guide portion 271, so that the air outlet 25 is exposed, which is conducive to the flow of the air flow.

[0100] Further, refer to Figure 7 As shown, the motion door panel 27 provided in this embodiment is provided with a reinforcement 273, and the thermal deformation of the reinforcement 273 is less than the thermal deformation of the motion door panel 27. After the fan heater stops working, the motion door panel 27 needs to be re-covered on the air outlet 25, and the position of the air outlet 25 is close to the heating chamber 16 and the heating assembly 14. Since the current motion door panel 27 is mostly made of plastic material, the residual heat after the two work will cause the motion door panel 27 made of plastic material to deform, and the deformed motion door panel 27 will be blocked from sliding in the guide part 271, which not only affects the aesthetics of the motion door panel 27, but also affects the normal sliding opening / closing process of the motion door panel 27. Therefore, the reinforcement 273 can be used to reduce the deformation of the motion door panel 27. The reinforcement 273 can be set along the extension direction of the motion door panel 27. The reinforcement 273 can be a metal part with a smaller thermal deformation than the plastic material, such as an aluminum part or an aluminum alloy part, which is light in weight and convenient to be set in the ceiling structure.
