The function of the drawings is to supplement the description in the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be understood as a limitation on the protection scope of the present utility model.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation on the present utility model.

[0022] In the present utility model, unless otherwise clearly defined, terms such as "arranged", "installed", and "connected" shall be understood in a broad sense. For example, they can be directly connected, or indirectly connected through an intermediate medium; they can be fixedly connected, or detachably connected, or integrally formed; they can be mechanically connected; they can be the communication inside two components or the interaction relationship between two components. Those skilled in the art can reasonably determine the specific meanings of the above terms in the present utility model in combination with the specific content of the technical solution.

[0023] Referring to Figures 1-4 , embodiments of the present application are proposed. The gas wall-mounted boiler described in this embodiment includes:

[0024] A controller 1, a box body 2, an air inlet pipe 4 that is internally communicated with the box body 2 through a blower 3, a gas pipeline that is internally communicated with the box body 2 through a gas proportional valve 5, and an air sensor 6 installed on the wall-mounted boiler;

[0025] The controller 1 is electrically connected to the blower 3, the gas proportional valve 5, and the air sensor 6. The air sensor 6 is used to obtain the air pressure and humidity inside the box body 2 and send them to the controller 1;

[0026] The controller 1 is used to adjust the rotation speed of the blower 3 when the received air pressure or humidity exceeds a preset range, and at the same time adjust the opening degree of the gas proportional valve 5 according to the rotation speed of the blower 3.

[0027] Both the air pressure and humidity inside the box body will affect the combustion efficiency of the gas furnace. Among them: the specific meaning that the controller 1 is used to adjust the rotation speed of the blower 3 when the received air pressure or humidity exceeds a preset range and at the same time adjust the opening degree of the gas proportional valve 5 according to the rotation speed of the blower 3 is as follows:

[0028] When the air pressure inside the box body 2 is higher than the preset range, the rotation speed of the blower 3 should be reduced to reduce the air intake during combustion to control the air pressure inside the box body 2. At the same time, the opening degree of the gas proportional valve 5 is adjusted to ensure the stability of the gas pressure, achieve stable combustion, high combustion efficiency, and reduce emissions;

[0029] When the air pressure during combustion is lower than the preset range, the rotation speed of the blower 3 should be increased to increase the air intake inside the box body 2 to increase the air pressure inside the box body 2. At the same time, the opening degree of the gas proportional valve 5 is adjusted to ensure the stability of the gas pressure, achieve stable combustion, high combustion efficiency, and reduce emissions;

[0030] When the humidity during combustion is higher than the preset range, the rotation speed of the blower 3 should be increased to increase the air intake inside the box body 2 and reduce the humidity inside the box body 2, reduce the generation of combustion condensate, avoid the corrosion of the heat exchanger and the burner caused by the generation of condensate. At the same time, the opening degree of the gas proportional valve 5 is adjusted to ensure the stability of the gas pressure, achieve stable combustion, high combustion efficiency, and reduce emissions.

[0031] The air pressure and humidity inside the box are obtained through the air sensor, and the controller adjusts the rotation speed of the blower according to the speed obtained by the air sensor, so as to achieve the best combustion condition during combustion, improve the combustion efficiency, and help reduce the emission of harmful gases.

[0032] Preferably, it further includes an air filter 7, and the air filter 7 is installed at the intake pipe 4, and is used for filtering the air sent into the box 2.

[0033] The cleanliness of the air is a powerful guarantee for the best combustion state. When particulate matter in the air enters the wall-hung boiler to participate in combustion, it may block the burner nozzle and further affect the combustion operation condition of the wall-hung boiler.

[0034] The air filter 7 is used for filtering the particulate matter entering the box 2. The filtering device can effectively isolate and adsorb the particulate matter in the filtering device, making the air participating in combustion clean, which is beneficial to further improving the combustion efficiency of the gas wall-hung boiler and also beneficial to ensuring the service life of the gas wall-hung boiler.

[0035] Based on the above content, the gas wall-hung boiler further includes an exhaust pipe 8 arranged in the intake pipe 4. The air filter 7 includes an annular bracket 71 and a filter element 72. The annular bracket 71 is sleeved on the exhaust pipe 8. The inner ring wall of the annular bracket 71 is connected to the exhaust pipe 8. The inside of the annular bracket 71 is hollow, and air intake holes are uniformly distributed on its outer ring wall, upper end and bottom wall. The filter element 72 is filled inside the annular bracket 71.

[0036] Refer to the attached Figures 2-3 As shown, air can enter from the upper end and side wall of the outer wall of the annular bracket 71, increasing the air intake area and improving the air intake efficiency on the premise of ensuring the filtering effect.

[0037] The filter element 72 is an air filter cotton. The upper end of the annular bracket 71 is open, which is convenient for users to clean and replace the filter cotton regularly, ensuring the filtering effect of the air filter 7 and the air cleanliness.

[0038] Certainly, the present invention is not limited to the above embodiments. Those skilled in the art can make equivalent deformations or replacements without departing from the spirit of the present invention, and these equivalent deformations and replacements are all included in the scope defined by the claims of this application.
