Description

Technical Field

[0001] The utility model belongs to the field of humidifiers, and particularly relates to a preheating device for the water inlet of a humidifier. Background Art

[0002] The working principle of an electrothermal humidifier is as follows: An electric heating tube is arranged inside. When in use, cold water is injected into the inside through a water inlet pipe and submerges the electric heating tube. By passing an electric current through the electric heating tube, heat is generated due to its resistance to heat the cold water to produce water vapor, and the water vapor is blown into the room to achieve the humidification effect.

[0003] However, when the existing electrothermal humidifier replenishes water, the cold water entering causes the water temperature to drop, resulting in obvious fluctuations in the output of steam volume. Therefore, it is necessary to continuously pass an electric current through the electric heating tube to repeatedly heat the cold water, leading to a relatively large power consumption of the heating tube. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a preheating device for the water inlet of a humidifier, which can significantly reduce the fluctuations in the steam output of the humidifier, thereby greatly reducing the power consumption of the heating tube.

[0005] To achieve the above object, the utility model provides the following technical solutions:

[0006] A preheating device for the water inlet of a humidifier, which is communicated with the water inlet pipe of the humidifier and is used for preheating the water inlet of the humidifier. It is characterized in that it includes: a heating base, which has a base length direction the same as the extension direction of the water inlet pipe and a base width direction perpendicular to the extension direction of the water inlet pipe. The heating base has a heating channel and a heat dissipation inner cavity. Through openings are respectively arranged at both ends of the heat dissipation inner cavity along the base length direction. A semiconductor heat exchange sheet is arranged inside the heat dissipation inner cavity. Among them, the heating channel is open at both ends along the base length direction, and the heating channel is communicated with the water inlet pipe. The heat dissipation inner cavity is formed inside the heating base, and the inner wall of the heat dissipation inner cavity opposite to the heating channel is used as a heat exchange sub-surface, and the semiconductor heat exchange sheet is attached to the heat exchange sub-surface.

[0007] Preferably, the heating base includes two semi-circular bases, which are symmetrically arranged and connected by threads. The semi-circular base includes a heating through groove and a semi-circular inner cavity. The openings of the two heating through grooves correspond to each other to jointly form the heating channel, and the semi-circular inner cavities are communicated to jointly form the heat dissipation inner cavity.

[0008] Furthermore, the semi-circular inner cavity is communicated through a pair of side openings on the surface of the semi-circular base, and the pair of side openings are respectively located on both sides of the heating through groove along the base width direction.

[0009] Furthermore, the semi-circular base further includes a base body and a base cover plate. A semi-circular inner cavity is formed inside the base body, and the semi-circular inner cavity is also open on the side of the base body away from the heating through groove. The base cover plate is arranged in a covering manner to close the semi-circular inner cavity.

[0010] Furthermore, a diversion fan is arranged on the base cover plate. The diversion fan is located inside the semi-circular inner cavity, and the wind direction is towards the semiconductor heat exchanger.

[0011] Preferably, the utility model further includes a pipe joint seat, which has an integrally formed bonding plate body and a communicating pipe body located in the middle of the bonding plate body. The bonding plate body is threadedly connected to the heating base along the seat length direction, and the heating is communicated with the water inlet pipe through the communicating pipe body.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. Since the humidifier water inlet preheating device of the utility model includes a heating base and a semiconductor heat exchanger, the heating base has a seat length direction and a seat width direction, the heating base has a heating channel and a heat dissipation inner cavity, the heating channel is communicated with the water inlet pipe, the heat dissipation inner cavity is formed inside the heating base, air inlets are respectively arranged at both ends of the heat dissipation inner cavity, the semiconductor heat exchanger is arranged inside the heat dissipation inner cavity, and the semiconductor heat exchanger is attached to the heat exchange sub-surface. Therefore, the water inlet of the humidifier passes through the heating channel of the utility model and is heated by the hot surface of the semiconductor heat exchanger. The cold surface of the semiconductor is in the heat dissipation inner cavity, and through the flowing air, the cold surface is maintained from frosting. That is, the utility model continuously heats the water inlet of the humidifier to a predetermined temperature, thereby being able to significantly reduce the fluctuation of the steam output of the humidifier, and there is no need for the heating pipe to have a long power-on heating time for heating the water inlet, so that the power consumption of the heating pipe is also greatly reduced.

[0014] 2. Since the heating base of the utility model includes two semi-circular bases, the two semi-circular bases are symmetrically arranged and threadedly connected. The semi-circular base includes a heating through groove and a semi-circular inner cavity. The openings of the two heating through grooves correspond to form a heating channel together, and the semi-circular inner cavities are communicated to form a heat dissipation inner cavity together. Therefore, the parts processing, manufacturing and installation of the utility model are relatively simple, and the heating efficiency is relatively high.

[0015] 3. Since the semi-circular base of the utility model further includes a base body and a base cover plate, a semi-circular inner cavity is formed inside the base body, and the semi-circular inner cavity is also open on the side of the base body away from the heating through groove. The base cover plate is arranged in a covering manner to close the semi-circular inner cavity. Therefore, the replacement and maintenance of the semiconductor heat exchanger of the utility model are more convenient.

[0016] 4. Since the base cover of the present utility model is provided with a diversion fan, the diversion fan is located inside the semi-circular cavity, and the air flow direction is towards the semiconductor heat exchanger, therefore, the present utility model makes the air flow in the heat dissipation cavity form a directional flow through the diversion fan, and the setting of the diversion fan is more convenient.

[0017] 5. Since the present utility model further includes a pipe joint seat, the pipe joint seat has a combined plate body and a connecting pipe body, the combined plate body is threadedly connected to the heating base, and the heating channel is communicated with the water inlet pipe through the connecting pipe body, therefore, the present utility model realizes the convenient connection between the heating channel and the water inlet pipe of the humidifier through the pipe joint seat.
