It is described further below with reference to effect of the attached drawing to the design of the utility model, specific structure and generation, with
It is completely understood by the purpose of this utility model, feature and effect.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model Domestic air source water heater.
Wherein: heating water tank 1, electric heating control module 2, inlet water sensor 3, water present sensor 4, water tank temperature sensor
5, high temperature-proof device 6, control module 7, electric heating module 8, relay 9, water tank main body 10.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below by taking air-conditioning system as an example,
In conjunction with accompanying drawings and embodiments, the present invention will be further described in detail.It should be appreciated that saying the specific implementation of description herein
Example is used only for explaining the utility model, is not used to limit the utility model.
As shown in Figure 1, Domestic air source water heater, including heating water tank 1 and electric heater frost protection device, the electric heating are protected
Protection unit includes electric heating control module 2, the inlet water sensor 3 for detecting inflow temperature, for detecting going out for leaving water temperature
Water sensor 4, the water tank temperature sensor 5 for detecting water tank temperature, high temperature-proof device 6 and control module 7, the control mould
Block 7 distinguishes the electric heating control module 2, inlet water sensor 3, water present sensor 4, water tank temperature sensor 5, high temperature-proof device
The water inlet of the heating water tank 1 is arranged in 6 connections, the inlet water sensor 3, and the water present sensor 4 is arranged described
The water outlet of heating water tank 1, the heating water tank 1 are provided with the electric heating module 8 for heating water, the electric heating control mould
Block 2 connects the electric heating module 8, and multiple temperature detection sensor is arranged, and controls from many aspects temperature, realizes more
The function of water heater is protected again.When water flow enters in the heating water tank 1 from water tank main body 10, pass through inlet water sensor 3
Detection, the water temperature that inlet water sensor 3 will test are sent to control module 7, the maximum amount angle value of the control setting of control module 7 into
Row compares, if water temperature overrate, control module 7 sends a signal to electric heating control module 2, electric heating control module
After 2 receive signal, control electric heating module 8 stops heating, when water temperature is lower than rated value, then controls the heating of electric heating module 8;
When water flow flows out in water tank main body 10 from heating water tank 1, by the detection of water present sensor 4, water present sensor 4 be will test
To water temperature be sent to control module 7, the maximum amount angle value of the control setting of control module 7 is compared, if water temperature is more than volume
Definite value, then control module 7 sends a signal to electric heating control module 2, and after electric heating control module 2 receives signal, control electricity adds
Thermal modules 8 stop heating, when water temperature is lower than rated value, then control the heating of electric heating module 8;When pass through water tank temperature sensor
5 detect the temperature of water tank, water temperature are sent to control module 7, the maximum amount angle value of the control setting of control module 7 is compared
Right, if water temperature overrate, control module 7 sends a signal to electric heating control module 2, and electric heating control module 2 connects
After the collection of letters number, control electric heating module 8 stops heating, when water temperature is lower than rated value, then controls electric heating module 8 and heats.
The high temperature-proof device is connected with relay 9, when control module 7 or inlet water sensor 3, water present sensor 4, water
Case temperature sensor 5 goes wrong when can not carry out control or water temperature detection, and high temperature-proof device 6 detects that water temperature is more than volume
Definite value sends a signal to relay 9, after relay 9 receives signal, control electric heating module 8 is forced to stop heating, protection heat
Hydrophone.
The preferred embodiment of the utility model is given in attached drawing.But the utility model can be with many different shapes
Formula is realized, however it is not limited to this specification described embodiment.On the contrary, purpose of providing these embodiments is makes to this reality
Understanding with novel disclosure is more thorough and comprehensive.
