Description

Technical Field

[0001] The utility model relates to the technical field of heaters, in particular to a heater fan with combustion monitoring function. Background Art

[0002] Heaters are devices used to provide heat and increase indoor temperature in cold weather. With the development of science and technology, the types and technologies of heaters have continued to evolve. The heaters on the market today are mainly divided into electric heaters, gas heaters, oil-filled heaters, infrared heaters, etc.

[0003] Gas heaters need to burn combustibles inside, and existing gas heaters use a single wind pressure to detect whether the fan is working, or detect the fan speed to detect whether the fan is working normally. The single wind pressure detection method, whether installed on the side of the heating wind wheel or the combustion wind wheel, cannot detect whether the combustion is normal to provide wind power to the outside. And by using the fan wind speed detection method on the side of the combustion wind wheel, it is also impossible to detect whether the air inlet is blocked or the smoke outlet is blocked, because the power of the heating wind wheel is much greater than that of the combustion wind wheel. Utility Model Content

[0004] The purpose of the utility model is to provide a reasonably designed heater fan with combustion monitoring to solve the defects and shortcomings of the prior art.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it includes a fixing plate, on which a motor is arranged, and on both sides of the motor are respectively provided a wind wheel housing one and a wind wheel housing two, a heating wind wheel is rotatably installed in the wind wheel housing one, and a combustion wind wheel is rotatably installed in the wind wheel housing two, the rotating shaft of the motor is respectively connected to the combustion wind wheel and the heating wind wheel, the front side of the wind wheel housing two is connected to an air inlet, the rear side of the wind wheel housing two is provided with an air outlet, and a wind pressure detection component is provided on the wind wheel housing two.

[0006] Preferably, the wind pressure detection component includes a first sampling port arranged on the side of the air inlet, the first sampling port is connected to the wind pressure sensor through connecting pipe 2, and a second sampling port is provided at the air outlet of wind wheel housing 2, and the second sampling port is connected to the wind pressure sensor through connecting pipe 1.

[0007] Preferably, the wind pressure sensor is a differential pressure wind pressure sensor, and the second connecting tube is connected to the negative pressure detection end of the wind pressure sensor, and the first connecting tube is connected to the positive pressure detection end of the wind pressure sensor.

[0008] Preferably, the wind wheel housing 1 and the wind wheel housing 2 are both formed by connecting a plurality of integrally formed structural parts.

[0009] After adopting the above structure, the beneficial effects of the utility model are:

[0010] The device monitors the combustion channel through dual-point wind pressure, and can monitor the combustion efficiency and blockage in real time. When blockage occurs, the blockage position can be quickly located through the wind pressure value, and the equipment can be shut down to protect it.

[0011] The device drives the heating wind wheel and the combustion wind wheel to operate simultaneously through a single motor, has a large air volume and low production cost.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 4As shown, the wind pressure detection assembly includes a first sampling port 9 arranged at the side of the air inlet 7, the first sampling port 9 is connected to the wind pressure sensor 10 through a second connecting pipe 12, and a second sampling port 8 is arranged at the air outlet of the second wind wheel housing 6, and the second sampling port 8 is connected to the wind pressure sensor 10 through a first connecting pipe 11;

[0022] The wind pressure sensor 10 is a differential pressure wind pressure sensor 10, and the second connecting tube 12 is connected to the negative pressure detection end of the wind pressure sensor 10, and the first connecting tube 11 is connected to the positive pressure detection end of the wind pressure sensor 10;

[0023] The wind wheel housing 1 4 and the wind wheel housing 2 6 are both formed by connecting a number of integrally formed structural parts.

[0024] The principle and use process of this utility model:

[0025] First, the fixing plate 1, the wind wheel housing 1 4 and the wind wheel housing 2 6 are connected and installed with bolts in sequence, and the air inlet 7 and the air outlet are connected to the upstream and downstream equipment respectively. At the same time, the detection ends of the wind pressure sensor 10 are connected and the output signal line is connected to the external control device. The wind pressure monitoring range is set, and the heater is started to work. The motor 2 drives the combustion wind wheel 5 and the heating wind wheel 3 to operate at the same time, and performs combustion and heat dissipation respectively;

[0026] The wind pressure sensor 10 obtains the pressure value from the first sampling port 9 and the second sampling port 8 in real time, and calculates the pressure difference between the two. When the motor 2 is not started, the wind pressure value is 0; after the fan is started, the wind pressure value changes, indicating that the equipment is operating normally;

[0027] When the air inlet 7 is blocked, the first pressure port is forcibly stirred and drawn by the fan, and the negative wind pressure increases significantly; while the second sampling port 8 cannot draw air from the air inlet 7, resulting in a decrease in positive pressure, causing the overall wind pressure difference to rise rapidly, and the output signal of the wind pressure sensor 10 changes rapidly, so that the external equipment can read the data and perform shutdown protection;

[0028] When the smoke exhaust port is blocked, the second pressure port is forced to push the wind by the fan, and the positive wind pressure rises significantly; while the wind pressure at the first sampling port 9 decreases, that is, the negative pressure decreases, and the wind pressure difference monitored by the wind pressure sensor 10 rises rapidly, and the output signal of the wind pressure sensor 10 changes rapidly. The external equipment can read the data and perform shutdown protection.

[0029] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation on the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
