Description

Technical Field

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

[0002] A humidifier is a household electrical appliance whose main function is to increase the humidity of indoor air to alleviate the impact of a dry environment on human health, furniture protection and comfort.

[0003] There are mainly the following types of humidifiers: 1. Ultrasonic humidifiers: use ultrasonic oscillators to atomize water into tiny droplets, blown out by fans, and quickly spread into the air. 2. Thermal evaporative humidifiers: water is heated to boiling by heating elements, generating steam that is released into the air. 3. Cold evaporative humidifiers (fogless humidifiers), usually use absorbent materials (such as wet curtains, fiber filters, sponges, etc.) as evaporation media. The water in the water tank is guided to the surface of the evaporation medium and naturally evaporates into water vapor. The evaporation process is accelerated by increasing the surface area and increasing air flow, rather than by ultrasonic oscillation or heating. Air circulation, the built-in fan draws dry indoor air into the humidifier, and when the air flows through the moist evaporation medium, the water is evaporated and mixed into the air. The humidified air is then blown out, gradually raising the indoor humidity.

[0004] In the prior art, in order to increase the humidification capacity of the mistless humidifier, it is generally achieved by increasing the surface area of ​​the water-absorbing material or increasing the power and speed of the fan. Increasing the surface area will increase the volume of the mistless humidifier. Increasing the power of the fan and increasing the speed of the fan will increase the noise. Utility Model Content

The outer shell 110 is provided with an installation cavity 111 and an air inlet 112, an air outlet 113 and a water adding port 114 connected to the installation cavity 111. The heating component 120 is arranged in the installation cavity 111, and can heat the air flowing into the air inlet 112. The wet curtain component 130 is arranged in the installation cavity 111, and can allow the heated air to flow through and humidify. The water tank 140 is arranged in the installation cavity 111. The water supply component 150 is configured to draw water from the water tank 140 to the wet curtain component 130. The air supply assembly 170 is installed in the installation cavity 111, and is configured to deliver dry air outside the outer shell 110 into the installation cavity through the air inlet 112, and heat the air through the heating assembly 120 and flow to the wet curtain assembly 130, and then humidify the heated air through the wet curtain assembly 130 and deliver it through the air outlet 113. The water adding member 180 is provided at the water adding port 114, and is configured to add water to the water tank 140.

[0080] In this embodiment, a heating assembly 120 is arranged in the outer shell 110, and the heating assembly 120 can heat the dry air flowing into the outer shell 110. After the heated air flows through the wet curtain assembly 130, the evaporation of water vapor in the wet curtain assembly 130 can be accelerated, thereby increasing the humidification amount. The water adding member 180 is arranged at the water adding port 114, so that water can be added to the water tank 140 without disassembling the outer shell 110, which is more convenient to use.

[0081] Please refer to Figures 1 to 8 In this embodiment, the water tank 140 is arranged at the bottom of the installation cavity. The wet curtain assembly 130 is arranged above the water tank 140, and a channel 131 is formed inside the wet curtain assembly 130. The heating assembly 120 is arranged at the outer periphery of the wet curtain assembly 130 and is spaced from the wet curtain assembly 130. The air inlet 112 is arranged on the side wall of the outer shell 110 and corresponds to the heating assembly 120. The water inlet 114 is arranged at the top of the outer shell 110, and the air outlet 113 is arranged at the outer periphery of the water inlet 114. The air supply assembly 170 is arranged above the wet curtain assembly 130 and is located below the water supply member 180. When the air supply assembly 170 is in operation, the outdoor dry air can flow through the air inlet, the heating assembly 120, and the wet curtain assembly 130 in sequence into the channel 131, and then be sent out from the air outlet 113 after passing through the channel 131. The water added through the water adding member 180 can flow into the water tank 140 through the channel 131 .

[0082] This embodiment can better save space and optimize the flow path through the above-mentioned spatial layout.

[0083] It should be noted that the mistless humidifier 100 of this embodiment has a three-layer layout of bottom, middle and top. The water tank 140 is arranged at the bottom, so that the center of gravity is lower and more stable during use. The heating component 120 and the water curtain component are arranged in the middle, so that the air flow path is relatively short and the wind resistance is small.

[0084] In this embodiment, the outer shell 110 includes a shell body 115 and a top cover 116. The top cover 116 is installed at the top opening of the shell body 115. The water inlet 114 and the air outlet 113 are both arranged on the top cover 116, and the water inlet 114 is arranged at the center of the top cover 116, in the shape of a concave groove. The air outlet 113 is arranged along the outer periphery of the water inlet 114, and the air outlet 113 is provided with an air outlet grille. The water adding member 180 is in the shape of a trumpet, forming a chamber that is larger at the top and smaller at the bottom. The water adding member 180 is installed at the water inlet 114.

The plurality of guide holes enclose a guide area, which can also be understood as the bottom wall of the water inlet 114 forming a guide area. The air supply assembly 170 includes a motor 171 and a fan blade 173. The fan blade 173 is mounted on the output shaft of the motor 171, and the motor 171 is mounted on the bottom of the top cover 116 and is located inside the diversion area. A diversion platform is protruded downward from the bottom of the top cover 116, so that the motor 171 can be illuminated inside. The water added to the water adding member 180 flows into the top cover 116 through the water adding port, and then flows out of the diversion hole after being diverted in the diversion area and flows to the channel 131.

[0085] The top cover 116 provided in this embodiment can realize water addition and air discharge, and can also be used to install the motor 171 of the air supply assembly 170. Most importantly, the motor 171 can be shielded by the structure of the cover, so as to prevent water from flowing onto the motor 171 when water is added, thereby causing the motor 171 to short-circuit. Secondly, it is also easy to assemble. When installing, the fan assembly is first assembled on the top cover 116, and then assembled to the shell body 115 by adding the top cover 116.

[0086] Please refer to Figures 1 to 8 In this embodiment, the mistless humidifier 100 further includes an air duct shell 190, and a flow channel 191 is formed inside the air duct shell 190.
