Description

Technical Field

[0001] The utility model relates to the field of household appliances, and in particular to a heating device for a fog-free humidifier and a fog-free humidifier. Background Art

[0002] Existing fogless humidifiers use physical means to force water molecules into the air, rather than producing visible water mist through high-pressure atomization or ultrasonic oscillation, to achieve fogless, clean, and healthy humidification effects. They are generally divided into two types: cold evaporation and hot evaporation.

[0003] The cold evaporative type uses a fan to introduce dry air into the equipment. The air passes through the moistened water curtain assembly, which accelerates the evaporation of water stored in the water curtain assembly under the action of the airflow, increases the air humidity, and converts liquid water molecules into gaseous water molecules that are mixed into the air, but its humidification energy is limited.

[0004] The thermal evaporation type heats water to boiling through an electric heating element to form steam, and then blows the hot steam into the room through a fan to increase the air humidity. However, it will bring the hidden danger of scale being difficult to clean, and because it is achieved by boiling water, the noise will increase during the boiling process. Utility Model Content

[0044] Example

[0045] Please refer to Figure 1 This embodiment provides a fog-free humidifier 300, which can heat the incoming air and use the airflow formed by the hot air to accelerate the evaporation of water vapor on the water curtain assembly, thereby improving the humidification capacity without forming scale and boiling water noise.

[0046] Please refer to Figure 2 In this embodiment, the mistless humidifier 300 includes an outer shell 310, a water curtain assembly 330, a water supply assembly 350, an air supply assembly 370 and a heating device 100. The heating device 100 is arranged in the outer shell 310. The water curtain assembly 330 is arranged inside the heating device 100. The outer shell 310 is provided with an air inlet 311. A water tank 313 is arranged in the outer shell 310, and the water supply assembly 350 can drain the water in the water tank 313 to the water curtain assembly 330. The outer shell 310 is provided with an air outlet 315. The air supply assembly is arranged in the outer shell 310. When the air supply assembly is operated, the outside air can enter the outer shell 310 through the air inlet 311, and flow into the heating device 100 after being heated by the heating device 100, and the heated air flows out from the air outlet 315 after passing through the water curtain assembly 330.

[0047] The mistless humidifier 300 provided in this embodiment is configured to place the water curtain assembly 330 inside the heating device 100, so that the heating device 100 can radiate and heat the water curtain assembly 330. Most importantly, when the air flows through the heating device 100, the heating device 100 can heat the air passing through, so that the air passing through becomes high-temperature air, so that when the high-temperature air flow blows to the water curtain assembly 330, the water curtain assembly 330 can form more water vapor than the air flow at normal temperature, thereby improving the humidification effect. Since the heating device 100 heats the air, it will not generate scale and water boiling noise compared to directly heating water.

[0048] Please refer to Figure 2 and Figure 3 In this embodiment, the heating device 100 includes a heat conductor 130 and an electric heater 110. A cavity 131 for mounting a water curtain assembly 330 is formed inside the heat conductor 130. The cavity 131 forms an opening 133 at least at the upper portion, so that the air flow carrying water vapor flows through the opening 133 to the air outlet 315 of the outer shell 310. The side wall of the heat conductor 130 is provided with a plurality of through holes 135 for flow. All the through holes 135 are connected to the cavity 131, and the heat conductor 130 is provided with a mounting portion 137. The electric heater 110 is mounted on the mounting portion 137 and is configured to convert electrical energy into heat to heat the heat conductor 130.

[0049] In this embodiment, a heat conductor 130 is provided, and a cavity 131 for installing a water curtain assembly 330 is formed inside the heat conductor 130, and the cavity 131 is formed with an opening 133 at least at the upper part, and a plurality of through holes 135 connected to the cavity 131 are provided on the side wall of the heat conductor 130, and the electric heating element 110 is installed on the heat conductor 130. The heat generated by the electric heating element 110 can be transferred to the heat conductor 130, thereby improving the heat exchange efficiency, so that the external air can better exchange heat with the heat conductor 130 when passing through the through holes 135 and near the heating element, and be heated to form a high-temperature airflow. The high-temperature airflow passing through the water curtain assembly 330 can cause the water curtain assembly 330 to evaporate more water, thereby improving the humidification capacity of the humidifier.

[0050] In this embodiment, the through hole 135 is in the form of a circular hole, which is evenly arranged on the outer contour of the heat conductor 130, so that the air in all directions can be heated. Of course, in some examples of the present application, the through hole 135 can also form a flow channel with a groove or the like.

[0051] Please refer to Figure 2 and Figure 3In this embodiment, the mounting portion 137 is disposed on the outside of the heat conductor 130 and is disposed close to the bottom of the heat conductor 130. The mounting portion 137 is disposed on the outside of the heat conductor 130 so that the electric heating element 110 will not come into contact with water or water vapor, which can increase the service life. The mounting portion 137 is disposed at the bottom, so that a temperature field environment is formed on the heat conductor 130, in which the temperature gradually decreases as the height of the heat conductor 130 increases. Based on the principle that hot air rises, the high-temperature airflow will rise and form an airflow field with a high temperature at the top and a low temperature at the bottom. The combination of the two allows the water curtain assembly 330 to evenly evaporate and generate water vapor.

[0052] In this embodiment, the heating device 100 further includes a fixing member 150. The mounting portion 137 is an annular groove disposed on the heat conductor 130. The annular groove is formed by stamping. The electric heating element 110 is annular and is a circular electric heating tube. The electric heating element 110 is installed in the annular groove and fixed to the annular groove by the fixing member 150.

[0053] In this embodiment, the electric heating element is configured as a ring-shaped electric heating tube, which can evenly heat the heat conductor 130 .

[0054] In this embodiment, the heat conductor 130 is in the shape of a round tube with openings 133 at both ends. The openings 133 at both ends can facilitate the installation of the water curtain assembly 330 inside.

[0055] In this embodiment, a heat-conducting flange is provided at the periphery of the through hole 135. The heat-conducting flange may be formed when the through hole 135 is formed by punching or may be fixed by other means at a later stage.

[0056] In this embodiment, a heat-conducting flange is provided on the periphery of the through hole 135 so as to better heat the airflow passing through the through hole 135 .

[0057] Please refer to Figure 4 In this embodiment, the heat conductor 130 is provided with a plurality of heat conducting fins 139. The heat conducting fins 139 can better achieve heat exchange with air. The heat conducting fins 139 can be provided on the inner periphery of the heat conductor 130, or on the outer periphery of the heat conductor 130, or on both the inner periphery and the outer periphery of the heat conductor 130.

[0059] Please refer to Figure 5 In this embodiment, a first mounting ring 317 is disposed in the outer shell 310, and a first limiting boss 319 is disposed on the mounting ring. The upper end of the heat conductor 130 abuts against the first mounting ring 317, and the first limiting boss 319 extends into the opening 133 and abuts against the inner wall of the heat conductor 130.

[0060] In this embodiment, the surface height of the upper end of the heat conductor 130 can be positioned by providing the first mounting ring 317. The first limiting boss 319 is provided to abut against the inner wall of the heat conductor 130, thereby achieving the limiting in the horizontal plane.

[0062] In this embodiment, the first mounting ring 317 is also provided with a first outer limiting protrusion 321 corresponding to the outer wall of the heat conductor 130, and the first outer limiting protrusion 321 abuts against the outer wall of the upper end of the heat conductor 130, so that the upper end of the heat conductor 130 is clamped between the first limiting protrusion 319 and the first outer limiting protrusion 321 to achieve a stable connection.

[0063] Please refer to Figure 6 In this embodiment, a second mounting ring 323 is provided in the outer shell 310, and the second mounting ring 323 is opposite to and spaced from the first mounting ring 317.

[0066] In this embodiment, the second limiting boss 325 is in the shape of a ring, and its head diameter is small, so it can be easily inserted into the opening 133 at the lower end of the heat conductor 130 to achieve limiting so that the heat conductor 130 and the water curtain assembly 330 are concentric.

[0067] In this embodiment, the second mounting ring 323 is also provided with a second outer limiting boss 327 corresponding to the outer wall of the heat conductor 130, and the second outer limiting boss 327 abuts against the outer wall of the lower end of the heat conductor 130, so that the lower end of the heat conductor 130 is clamped between the second limiting boss 325 and the second outer limiting boss 327 to achieve a stable connection.

[0071] In summary, the working principles and beneficial effects of the heating device 100 and the fog-free humidifier 300 provided in the embodiment of the utility model include:

[0072] The mistless humidifier 300 provided in this embodiment is provided with a water curtain assembly 330 inside the heating device 100, so that the heating device 100 can radiate and heat the water curtain assembly 330. Most importantly, when the air flows through the heating device 100, the heating device 100 can heat the air passing through, so that the air passing through becomes high-temperature air, so that when the high-temperature air flow blows to the water curtain assembly 330, the water curtain assembly 330 can form more water vapor than the air flow at normal temperature, thereby improving the humidification effect.
