Description

The water heater controller

Technical field

The utility model relates to a kind of water heater control system, especially a kind of water heater controller.

Background technology

Along with scientific and technological progress, people are also improving constantly for the requirement of the control system of domestic hot-water's heat supply, and water heater is divided into combustion gas class water heater and electric heating water heater substantially in the market, and the solar water stove.Consider that from the practicality of life combustion gas class water heater has very big development space, and most of in the market combustion gas class water heater product uses with air-conditioning, bathing and kitchen and is main purpose, control system is fairly simple, and only to water temperature, basic parameters such as the water yield are monitored.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of water heater controller is provided, gas valve, triple valve and pump loop control are integrated in one, not only can monitor water temperature, the water yield, can also control water temperature, the water yield, combustion gas tolerance and water pump circulation.Improved the reliability that system uses, be fit to different types of machines and use.

According to the technical scheme that the utility model provides, a kind of water heater controller comprises the control circuit board in casing, panel and the casing; MCU, EPROM chip and responsible powered switch Power Entry Module are arranged on the described control circuit board; The EPROM chip has the rechargeable battery of independent power supply; The input of described MCU connects water temperature signal input module, water level signal input module and touch key-press input module respectively; The output of described MCU connects gas valve driver module, magnetic valve output module, pump output module respectively; Described touch key-press input module connects the touch key-press on the panel; The output of described MCU also is connected with alarm output module and LCD shows output module, and LCD shows that output module connects the LCD display on the panel;

Described touch key-press is established the SET key, the key that shifts left, superior displacement key, down shift key, dextroposition key, minute adjust key, clock is adjusted key, FN key and power key; Wherein the SET key must be earlier by this key when function setting, presses SET key+FN key and does not put for two seconds, and then all data make zero and turn back to factory setting; The key that shifts left is a circulating pump automatic switch key, opens or the power supply that switches off the pump by this key; When the superior displacement key is provided with state, play the effect of upward displacement by this bond energy; When following shift key is provided with state, play the effect of downward displacement by this bond energy; The dextroposition key is the gas valve opening key, opens or close the gas check valve power supply by this key; Minute adjust key and adjust minute, pin and do not put then fast rise; Clock is adjusted key and is adjusted clock, pins and does not put then fast rise; The FN key is the function Macintosh; Power key is the switch activated of controller.

The utlity model has following advantage:

1. adopt the design of Switching Power Supply supply module, can be fit to the requirement of multiple voltage adaptability.

2. adopt the touch key-press design, promote the input use feeling of product.Touch key-press cooperates with LCD display can realize a preset water level, and the gear of water level can be set by function key.The full automatic stop of water, thereby the work of control magnetic valve; B presets water temperature, realizes that by function key the heating-up temperature of 0-99 degree is set; The circulation of c pipeline, circulating pump started every 20 minutes, and be 10 minutes the duration of runs; Closed again after 10 minutes 20 minutes, and circulated with this; The d memory of cutting off the power supply, there are rechargeable battery and EPROM chip in controller inside, still can preserve current information and setup parameter when having a power failure; Contact button is invalid this moment; The f time showing shows the current time, and the user can adjust the time voluntarily; The dazzling LED of g shows, can show various functions such as water temperature value, temperature approach.High contrast led light source; In the time of at night, more apparent brilliant; The h fault shows, will be presented at fault-signal on the display screen in real time if instrument self breaks down.

Description of drawings

Fig. 1 is the utility model shape assumption diagram;

Fig. 2 is the utility model circuit block diagram.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

As Fig. 1, shown in Figure 2, a kind of water heater controller comprises the control circuit board in casing 1, panel 2 and the casing; MCU, EPROM chip and responsible powered switch Power Entry Module are arranged on the described control circuit board; The EPROM chip has the rechargeable battery of independent power supply; The input of described MCU connects water temperature signal input module, water level signal input module and touch key-press input module respectively; The output of described MCU connects gas valve driver module, magnetic valve output module, pump output module respectively; Described touch key-press input module connects the touch key-press 3 on the panel 2; The output of described MCU also is connected with alarm output module and LCD shows output module, and LCD shows that output module connects the LCD display 4 on the panel 2;

Described touch key-press 3 is established the SET key, the key that shifts left, superior displacement key, down shift key, dextroposition key, minute adjust key, clock is adjusted key, FN key and power key;

The SET key must be earlier by this key when function setting, presses SET key+FN key and does not put for two seconds, and then all data make zero and turn back to factory setting;

The key that shifts left is a circulating pump automatic switch key, opens or the power supply that switches off the pump by this key; Press the key that shifts left, buzzer rings, and the pipe circle pump automatic function is opened.Click the key that shifts left again, buzzer rings twice automatic functions and cuts out.Dispatch from the factory to be defaulted as and close.

When the superior displacement key was provided with state, this bond energy of eucalyptus played the effect of upward displacement;
