Embodiment Construction
[0039] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0040] like figure 1 and figure 2 As shown, the present invention provides a gas water heater, which includes a casing 1, and a gas valve 2, a fan 3, a combustion device 4, a heat exchange device 5, a controller 6, etc. are installed in the casing 1. A water inlet and outlet 7 and an exhaust outlet 8 are installed on the casing 1, the water inlet and outlet 7 are connected to the water inlet and outlet pipes, and the exhaust outlet 8 is connected to the exhaust pipe. to the outside.
[0041] like figure 1 As shown, one air inlet 9 is respectively arranged on the side walls on both sides of the housing 1 , and only one air inlet 9 can be provided, or can be arranged at other positions such as the rear wall and the front panel of the housing 1 . A filtering device 10 is installed at each air inlet 9 .
[0042] like image 3 As shown, the fi...

The invention relates to a control method for filter device blockage, a control device and a gas water heater. A wind speed detecting device is utilized to monitor the inlet wind speed in real time, according to the detected wing speed value, the blockage state of the filter device is judged, and according to the blockage state, the revolving speed of a draught fan is correspondingly adjusted. According to the control method for the filter device blockage, the control device and the gas water heater, oil removal and dust removal can be carried out on the air which enters the water heater, theair burning quality is effectively improved, the service life of the water heater is prolonged, the inlet wind speed can be monitored in real time through the wind speed detecting device, a controlleris used for controlling the working state of the wind supply draught fan according to the detecting result, the wind supply requirement of heating of the water heater is ensured, and the safety and reliability of work are further improved.
Description
technical field [0001] The invention relates to a control method and a control device for clogging of a filtering device, and also relates to a gas water heater adopting the control method and the control device. Background technique [0002] At present, domestic gas water heaters are mainly of the forced exhaust type, and most of them are installed in the kitchen. When the gas water heater is in use, the combustion air is taken from the room. Since the installation environment of the water heater is relatively poor and it is in an environment with serious oil pollution, when the water heater is working, the air sucked into the interior through the air inlet contains a lot of oil and dust. After the water heater is used for a period of time, the surface and inner surface of the parts will be covered with oil and dust, especially the fans, burners, heat exchangers and valve bodies. The plummeting has seriously affected the service life of the water heater, and it is easy to ...
