Embodiment 1
[0037] like figure 1 As shown, a water heater control method that can adapt to a variety of calorific value gas, the water heater calls the matching parameters according to the air pressure value and the type of gas source selected by the user, so that the proportional valve current and fan speed work according to the corresponding parameters.
[0038] Described method specifically comprises the steps:
[0039] 11) Pre-store the best parameters corresponding to different air pressure values and different types of air sources into the water heater;
[0040] 12) The water heater is turned on and powered on, and enters the setting mode under user control;
[0041] 13) The user selects the air pressure value and air source type that match its use conditions;
[0042] 14) The water heater invokes the best parameters that match the air pressure value and air source type selected by the user, and makes the water heater memorize the matched parameters;
[0043] 15) The water heat...
Embodiment 2
[0051] like figure 2 As shown in Fig. 1, a water heater control method that can adapt to a variety of calorific value gas, the user selects the corresponding working mode according to the altitude value and the type of gas source, and the water heater calls the matching parameters to make the proportional valve current and fan The speed works according to the corresponding parameters.
[0052]Because, when the altitude rises, the air pressure value keeps decreasing; when the altitude drops, the air pressure value keeps increasing. Different altitude values correspond to different rotational speed values of the fan, and the rotational speed value of the fan increases or decreases with the increase of the altitude value.
[0053] The working modes of the water heater are divided into the following: the first working mode, at this time, the user selects when the water heater is at a high altitude. Preferably, when the altitude is above 2000m, the first working mode is sele...

Abstract
The invention relates to a method for controlling a water heater adaptable to gas with various heat values. The method includes that the water heater invokes matched parameters according to air pressure values and gas source types selected by a user to enable proportional valve current and fan rotating speed to work according to corresponding parameters; after the water heater is powered on, the user selects to enable the water heater to enter a setting mode; the user selects modes corresponding to altitude at which the water heater is positioned and the gas source types from a first working mode to an nth working mode; the water heater invokes working parameters corresponding to the selected working modes; after program recognition and automatic memory, the user enables the water heater to exit the setting mode; the water heater enters a working procedure, proportional valve current and fan rotating speed of the water heater work according to corresponding parameters. From the first working mode to the nth working mode, values of proportional valve current and fan rotating speed sequentially change according to rule changes. Consequently, the control process that the user selects manually and the water heater automatically matches parameters is realized, and misjudgment of the water heater is reduced greatly.
Description
technical field [0001] The invention relates to the field of water heaters, in particular to a water heater control method that can adapt to various calorific value gases. Background technique [0002] Most of the gas water heaters on the market can only adapt to the gas source of a single calorific value, and do not consider the altitude of the user's area, so that the user encounters a lot of troubles during use. For example, when the air source of the user's home changes, it needs to be repurchased or remodeled, resulting in a great waste of materials and costs. [0003] In view of this, in order to solve the above problems, some gas water heaters that can automatically adapt to various gas sources through software control are also provided on the market. [0004] For example, the Chinese patent whose application number is CN201110024695.3 is an adaptive gas water heater gas source control method. It adjusts the size of the change interval according to the secondary pre...
