Abstract
The invention discloses a composing method of an instant electric water heater with scald-preventing function. A temperature probe which is connected with a microcomputer is arranged on a water outlet pipe of a heating body, an electromagnetic valve which is controlled for switching by the microcomputer is arranged between a water inlet pipe and the water outlet pipe of the heating body, when water is cut off suddenly or the water temperature in the heating body rises rapidly due to other reasons, the microcomputer opens the electromagnetic valve, large quantity of cold water enters the electromagnetic valve and flows out after being mixed with hot water in the water outlet pipe. The instant electric water heater with the scald-preventing function comprises the heating body, the water inlet pipe and the water outlet pipe, wherein, the temperature probe which is connected with the microcomputer is arranged on the water outlet pipe, the electromagnetic valve which is controlled for switching by the microcomputer is arranged between the water inlet pipe and the water outlet pipe.
Description
Technical field:
The present invention relates to household electrical appliance technical field, especially relate to the immediately heating water heater technical field.
Background technology:
Immediately heating water heater is a kind of common household electrical appliance, and this water heater is because instant-heating, therefore often intermittently switching in use.Present most water heater suspends in the shower process when opening again after supplying water, phenomenon takes place to scald easily, though this is because heater block stops heating, but be trapped in the waste heat that the interior water of water heater has absorbed parts such as thermal conductor, water pipe, water temperature is raise rapidly, this moment, the user directly used these high-temperature water, easily scalded skin.
Summary of the invention:
The objective of the invention is to the weak point that exists at prior art and a kind of composing method of instant electric water heater with scald-preventing function is provided, a kind of water heater with scald-preventing function is provided simultaneously.
For achieving the above object, composing method of instant electric water heater with scald-preventing function of the present invention is that the temp probe that links to each other with micro computer is set on the outlet conduit of calandria, and the magnetic valve that is opened and closed by microcomputerized control is set between the inlet channel of calandria and outlet conduit, when cutting off the water supply suddenly or other reasons and when water temperature in the calandria is raise rapidly, micro computer is opened magnetic valve, make a large amount of cold water enter magnetic valve, and mix the back with hot water in the outlet conduit and flow out.
In above-mentioned composing method of instant electric water heater with scald-preventing function, the internal diameter of magnetic valve is greater than the internal diameter of outlet conduit.
The instant electric water heater with scald-preventing function who obtains according to said method includes calandria, inlet channel and outlet conduit, wherein, described outlet conduit is provided with the temp probe that links to each other with micro computer, is provided with the magnetic valve that opens and closes by microcomputerized control between inlet channel and the outlet conduit.
The internal diameter of described magnetic valve is greater than the internal diameter of outlet conduit.
Beneficial effect of the present invention is: owing to be provided with the magnetic valve that is opened and closed by microcomputerized control between inlet channel and outlet conduit, when cutting off the water supply suddenly or other reasons and when water temperature in the calandria is raise rapidly, micro computer can be opened magnetic valve, make a large amount of cold water enter magnetic valve, and mix the back with hot water in the outlet conduit and flow out, avoided the phenomenon of hot water scalded skin, security is very high.
Description of drawings:
The present invention is described further below in conjunction with accompanying drawing:
Accompanying drawing 1 is an overall structure schematic diagram of the present invention.
The specific embodiment:
The following stated only is preferred embodiment of the present invention, does not therefore limit protection scope of the present invention.
See shown in Figure 1: the composing method of instant electric water heater with scald-preventing function of the present invention is that the temp probe 31 that links to each other with micro computer 40 is set on the outlet conduit 30 of calandria 10, and the magnetic valve 50 that is opened and closed by micro computer 40 controls is set between the inlet channel 20 of calandria 10 and outlet conduit 30, when cutting off the water supply suddenly or other reasons and when water temperature in the calandria 10 is raise rapidly, micro computer 40 is opened magnetic valve 50, make a large amount of cold water enter magnetic valve 50, and mix the back with hot water in the outlet conduit 30 and flow out.
The instant electric water heater with scald-preventing function who obtains by above-mentioned constructive method includes the calandria of being made by red copper or stainless steel material 10, inlet channel 20 and outlet conduit 30, temp probe 31, micro computer 40 and the magnetic valve 50 of three-way pipe pattern, wherein, temp probe 31 is arranged on the outlet conduit 30, and link to each other with micro computer 40, the two ends of controlling the magnetic valve 50 that opens and closes by micro computer 40 link to each other with inlet channel 20 with outlet conduit 30 respectively, and the internal diameter of magnetic valve 50 is greater than the internal diameter of outlet conduit 30.
Instant electric water heater with scald-preventing function of the present invention in use, when occurring cutting off the water supply suddenly or other reasons and water temperature in the calandria 10 that causes when raising rapidly, temp probe 31 is transferred to micro computer 40 with temperature data, 40 Data Control magnetic valves 50 that provide according to temp probe 31 of micro computer are opened magnetic valve 50.At this moment, cold water enters from inlet channel 20, because the internal diameter of outlet conduit 30 is less than magnetic valve 50, so a large amount of cold water are by magnetic valve 50, have only a small amount of cold water to enter calandria 10,, flow out after the cold water mix that high-temperature water in the outlet conduit 30 and magnetic valve 50 flow into and use for the user so calandria 10 has only a small amount of high-temperature water by outlet conduit 30, thereby avoided high-temperature water to scald the possibility of user's skin, security is very high.After water temperature in cold water makes calandria 10 was reduced to safe temperature, calandria 10 restarted heating again.
