As shown in FIG. 1 to FIG. 3 , the present invention provides a liquid heating type electric heater 100 comprising a casing 110 , a heat pipe unit 160 , a heating unit 190 and a control circuit board 200 . The casing 110 includes a receiving chamber 120 that houses a liquid 150.

The heat pipe unit 160 is disposed in the accommodating chamber 120, and the heat pipe unit 160 includes a plurality of heat pipes 170. The heat pipe 170 described herein preferably refers to at least one heat pipe that is bendable, and the heat pipe 170 is made of copper or an alloy thereof. In the present embodiment, a plurality of heat pipes 170 are preferably provided. However, in other different embodiments, a single continuous bent heat pipe 170 may be provided. One end of each heat pipe 170 is in contact with the liquid 150, and the other end is disposed away from the liquid 150. The heating unit 190 is used to heat the liquid 150, and the control circuit board 200 is electrically connected and controls the heating unit 190.

As shown in FIG. 1 and FIG. 3, a cover body 112 connected to the casing 110 and a fan unit 210 disposed in the cover body 112 may be further included. The fan unit 210 may have a separate wafer unit (not shown) or The connection control circuit board 200 is connected. The rotational speed of the fan unit 210 described above may be changed according to the setting of the control circuit board 200. In addition, the cover body 112 further includes an air inlet 130 and an air outlet 140 that are in communication. The fan unit 210 is disposed adjacent to the inside of the intake port 130. A partition 220 is further disposed between the cover 112 and the casing 110 to partition the accommodating chamber 120 into a heat pipe groove 122 and a liquid tank 124 and respectively isolate the liquid 150 and the fan unit 210.

In the present embodiment, each heat pipe 170 of the heat pipe unit 160 is disposed between the air inlet 130 and the air outlet 140 and is positioned by the partition 220. In addition, the heat pipe unit 160 is disposed in the heat pipe slot 122, and the liquid 150 is received in the liquid tank 124.

When the heating unit 190 heats the liquid 150, which is preferably water, each heat pipe 170 absorbs heat from the liquid 150 and is transferred to the upper half of the accommodating chamber 120. Heat is blown out of each of the heat pipes 170 by the fan unit 210 out of the air outlet 140 of the casing 110. Therefore, the electric heater 100 of the present embodiment not only provides thermal energy, but also blows an appropriate amount of moisture to increase the appropriateness.

In addition, each of the heat pipes 170 is further provided with a plurality of heat dissipation fins 180 , and each of the heat dissipation fins 180 is respectively mounted on each of the heat pipes 170 . When the user turns off the power of the heater 100, each of the heat dissipation fins 180 can assist in eliminating the residual heat of each heat pipe 170.

As shown in FIG. 1 , the control circuit board 200 further includes a temperature control water level sensor 250 , at least one control switch 260 , and a power module 300 . When the temperature of the liquid 150 is too high, the temperature-controlled water level sensor 250 sends a signal (not shown) to the control circuit board 200, and the heating unit 190 is controlled to stop heating. When the water level of the liquid 150 is insufficient, the temperature-controlled water level sensor 250 sends a signal (not shown) to the control circuit board 200 to cut off the power to stop the operation of the heater 100. The power module 300 is connected to the mains to provide electric energy to the electric heater 100.

In addition, please refer to FIG. 2 and FIG. 3 together, the box body 110 further includes a screen 230, a check valve 240, a liquid injection port 270 and a liquid level indicator 280. The screen 230 is disposed at the intake port 130 to filter dust, impurities, and the like in the air taken into the air by the fan unit 210. The check valve 240 prevents the liquid 150 from overflowing, and allows the hot air in the accommodating chamber 120 to escape. The liquid level marker 280 allows the user to visually see if the liquid 150 is sufficient, and the user can replenish the liquid 150 from the liquid injection port 270. As shown in FIG. 3, the check valve 240 or the liquid injection port 270 may be disposed on the partition plate 220 or in the vicinity of the tank 110 near the liquid 150, and is not limited.

When the user operates at least one of the control switches 260 of the control circuit board 200, the heating unit 190 heats the liquid 150 to produce a temperature rise effect. Each heat pipe 170 absorbs heat of the liquid 150, and the fan unit 210 generates heat convection to diffuse heat energy from the heat pipes 170 of the heat pipe unit 160. At this time, due to the evapotranspiration of the liquid 150 and the siphoning, the humidity can be increased at the same time, so that the operation of the electric heater 100 is achieved.

In summary, the embodiments disclosed herein are to be considered as illustrative of the present invention and are not intended to limit the present invention. The scope of this creation is defined by the scope of the appended patent application and covers its legal equivalents and is not limited to the foregoing description.
