DETAILED DESCRIPTION

[0024] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0025] like Figure 1-Figure 2A semiconductor electric wall-mounted boiler shown includes a shell 10 and a semiconductor heating element 20, a controller component 30 and a temperature control component 40 arranged in the shell 10; the end of the semiconductor heating element 20 close to the bottom of the shell 10 is a water inlet end, and the end of the semiconductor heating element 20 close to the top of the shell 10 is a water outlet end; the temperature control component 40 is fixedly connected to the water outlet end of the semiconductor heating element 20, and the controller component 30 is electrically connected to the temperature control component 40 and the semiconductor heating element 20.

[0026] Based on the above structure, the water inlet end of the semiconductor heating element 20 is connected to a water inlet pipe 50 that passes through the bottom of the shell 10, and the water outlet end of the semiconductor heating element 20 is connected to a water outlet pipe 60 that passes through the top of the shell 10. The temperature control component 40 is connected to the water outlet pipe 60. Here, the semiconductor heating element 20 uses PTC heating ceramics.

[0027] On the basis of the above structure, the semiconductor electric wall-mounted boiler also includes a water pump; the water pump is arranged outside the shell 10 and is connected to the water inlet pipe 50 through a pipeline; a water pump connection terminal 80 is reserved on the controller component 30.

[0028] Based on the above structure, the temperature control component 40 includes a limit temperature controller 41 and a temperature sensor 42 .

[0029] Based on the above structure, a terminal block 90 and a leakage protection coil 100 are also provided in the shell 10; the terminal block 90 and the leakage protection coil 100 are electrically connected; the leakage protection coil 100 is electrically connected to the controller component 30, and here, the terminal block 90 is set as a 4-position terminal block.

[0030] Based on the above structure, the semiconductor heating element 20 is fixed in the shell by a fastening assembly 70. Specifically, the fastening assembly 70 includes a connecting plate 71 and a threaded fastener 72; the outer periphery of the water inlet pipe 50 and the water outlet pipe 60 are respectively fixedly sleeved on the connecting plate 71; the threaded fastener 72 is used to fix the connecting plate 71 to the inner top and inner bottom of the shell 10. Here, the threaded fastener 72 is preferably a bolt. Through the design of the above-mentioned fastening assembly 70, the semiconductor heating element 20 is fixed on the bottom plate and the top plate, so that the semiconductor heating element 20 is easy to replace and connect, which is easy and convenient, and will not spend a lot of time on disassembly. At the same time, it will not easily rotate and fall off, and it is quick and reliable.

[0031] The control process of the semiconductor electric wall-mounted boiler is as follows:

[0032] 1) Heating process: When T outlet water temperature < T set temperature - T return temperature, the controller component 30 determines that there is a heating demand, the water pump starts, and the controller component 30 energizes the semiconductor heating element 20 for heating until T outlet water temperature > T set temperature + 5, then stops heating and enters the insulation stage, the water pump turns 3 and stops 7; during the heating of the semiconductor heating element 20, the controller component 30 continuously detects the outlet water temperature. If the temperature rises too fast (3-15°C per second, which can be set), a fault is reported.

[0033] 2) Antifreeze protection: Level 1 antifreeze (water pump runs for a long time without heating), the heating water outlet temperature (X) is 6℃≤X≤10℃, which is the default level 1 antifreeze. When the heating water outlet temperature is ≥11℃, the water pump continues to run for 1 minute before exiting the level 1 antifreeze; enter the level 2 antifreeze (heating), the heating water outlet temperature (X) is 2℃≤X≤5℃, which is the default level 2 antifreeze. The controller energizes the heating element for heating. When the heating water outlet temperature is ≥15℃, the heating element continues to heat for 1 minute before exiting the level 2 antifreeze.

[0034] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
