Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more particularly to a humidifier. Background Technology

[0002] With the improvement of people's living standards and the pursuit of a healthy environment, humidifiers have become a necessity for many families. Humidifiers use humidifying components to humidify and ventilate, thereby increasing the humidity of indoor air and improving the comfort of the living environment.

[0003] To improve humidification efficiency, some humidifiers use heating elements to heat the water in the tank and then spray the heated water onto the humidification components to increase the evaporation rate, allowing the components to release moisture into the air more quickly. In cold, dry winters, warm, humid air also provides a more comfortable humidification experience. However, these humidifiers have low efficiency in heating the entire tank, making them unsuitable for scenarios requiring rapid adjustment of indoor humidity. Utility Model Content

[0004] This application discloses a humidifier that heats the water pumped out by a water pump and then sprays the heated water into the humidification component, enabling the humidifier to quickly respond to the user's humidification needs and improving the humidification efficiency of the humidifier.

[0005] To achieve the above objectives, this application discloses a humidifier, comprising: a housing having a receiving cavity formed therein; a water tank detachably disposed from the housing; a humidifying component located within the receiving cavity and detachably disposed within the water tank; and a water circuit assembly disposed within the housing for conveying water from the water tank to the humidifying component; the water circuit assembly includes a heating element located within the inner cavity of the humidifying component.

[0006] In one possible implementation, the heating element is a thermistor heating element.

[0007] In one possible implementation, the heating element has a protective layer inside.

[0008] In one possible implementation, the heating element is provided with a flame-retardant insulation layer on its exterior.

[0009] In one possible implementation, at least a portion of the heating element is a conduit through which the water circuit assembly delivers water from the water tank to the humidification assembly via the conduit.

[0010] In one possible implementation, the water circuit assembly further includes: a water pump in communication with the heating element; a first housing, wherein the water pump is disposed in the first housing; and a second housing, wherein the heating element is disposed in the second housing, and the heating elements are arranged in the second housing and the first housing along the height direction of the humidifier.

[0011] In one possible implementation, the humidifier includes an electrical control box and an electrical connection cable electrically connected to the electrical control box. The top of the second housing is provided with a wire passage area, and the electrical connection cable extends into the wire passage area and is electrically connected to the heating element.

[0012] In one possible implementation, the waterway component further includes:

[0013] A water level sensor is used to detect the water level in the water tank, and the water level value obtained by the water level sensor is used by the control device of the humidifier to control the operation of the heating element.

[0014] In one possible implementation, the humidifier further includes a water outlet pipe connected to the heating element, the water outlet pipe including a first water outlet in a vertical direction, the first water outlet corresponding to the top of the humidification assembly.

[0015] In one possible implementation, the humidifier further includes a temperature sensor disposed at the first water outlet to detect the temperature of the water flowing out from the heating element.

[0016] In one possible implementation, the humidifier further includes: a fan assembly disposed within the housing, the fan assembly including an air inlet; and a ventilation grille disposed around the water circuit assembly, the ventilation grille being disposed at the air inlet.

[0017] In one possible implementation, the housing includes a communicating air inlet and an air outlet, forming an airflow channel between the air inlet and the air outlet, and the humidification component is located within the airflow channel;

[0018] The humidifier includes a ventilation grille connected to the hollow part, and the ventilation openings on the ventilation grille are connected to the air inlet and the air outlet.

[0019] The humidifier provided in this application embodiment utilizes a water circuit assembly as the working component for heating the water in the water tank. By adding a heating element to the water circuit assembly, heating a small volume of water (part of the water flowing out of the tank) is achieved, significantly improving the humidifier's response speed and energy efficiency. Furthermore, the heating element is located outside the water tank, avoiding the safety risks that might arise from prolonged immersion of the heating element in water, thus improving the humidifier's safety and reliability. Simultaneously, the water circuit assembly serves both to supply water to the humidification component and to heat the water, optimizing the humidifier's structure and allowing for further compactness and miniaturization.

Unless otherwise stated, "a plurality of" means two or more.

[0034] With the improvement of living standards and people's increasing attention to a healthy environment, humidifiers have become an indispensable home appliance for many families. Humidifiers release moisture into the air through humidifying components, effectively regulating indoor humidity and improving the comfort of the living environment. The effect of humidifiers is even more significant, especially in dry seasons or air-conditioned environments.

[0035] Some humidifiers in this technology employ a humidification scheme using hot water spray humidification components. This accelerates the evaporation rate of water in the humidification components and provides users with warm, humid air during cold, dry winters, resulting in a more comfortable humidification experience.

[0036] However, the water heating method used in these humidifiers typically involves heating the entire tank of water. For example, a heating element is installed inside or outside the water tank to heat the water. Since the water tank has a limited capacity, heating the entire tank takes a long time, making it difficult to meet users' needs for rapid humidification. Especially in scenarios requiring rapid humidity adjustment, the heating speed and humidification effect of this type of humidifier may be insufficient.

[0037] Based on this, this application provides a humidifier with a water circuit assembly that delivers water from a water tank to the humidifier for humidification. The water circuit assembly also includes a heating element that heats water drawn from the water tank. The heating element heats a small volume of water, resulting in a rapid temperature increase, thus enabling the humidifier to respond quickly to humidification needs.

[0038] Please refer to the following: Figure 1 and Figure 2 This application provides a humidifier 100. The humidifier 100 includes a housing 10, within which a receiving cavity 10a is formed. A humidification assembly 30, a fan assembly 70, and a water circuit assembly 40 are disposed within the receiving cavity 10a. A water tank 20 may be disposed within the housing 10 or exposed outside the housing 10, for example, the housing 10 may overlap the top of the water tank 20.

[0039] like Figure 1As shown, the housing 10 includes an air inlet 101 and an air outlet 102. The air inlet 101 is located on the side wall of the housing 10 and corresponds to the humidification component 30. The air outlet 102 is located on the top of the housing 10, and an airflow channel is formed between the air inlet 101 and the air outlet 102. The humidification component 30 is located within the airflow channel. The airflow entering the housing 10 from the air inlet 101 passes through the humidification component 30 to form a humidified airflow, and then passes through the fan assembly 70 before being discharged from the air outlet 102, thereby humidifying the indoor environment.

[0040] The housing 10 can be the exterior part of the humidifier 100 and provide structural support and protection for the structural parts and electrical components of the humidifier 100 (e.g., the fan assembly 70).

[0041] In some embodiments, the water tank 20 is located at the bottom of the humidifier 100. The humidification assembly 30 is detachably disposed from the water tank 20.

[0042] The humidification component 30 may include a wettable filter material made of hydrophilic polymer composite materials or natural / synthetic fiber fabrics. The surface of the wettable filter material may be treated with a nano-coating or gradient porosity to optimize capillary water absorption performance. The wettable filter material forms a high specific surface area air-water contact interface through a multi-layer composite or three-dimensional honeycomb structure, and is equipped with an antibacterial agent or anti-mildew coating to resist biofouling. The wettable filter material may be equipped with a support frame integrating flow channels or asymmetric corrugated units to directionally guide airflow and moisture diffusion paths. At the same time, the humidification component 30 can be a modular assembly structure of the wettable substrate, adaptable to detachable installation interfaces with different assembly requirements.

[0043] In some embodiments, the housing 10 is detachably fitted onto the outside or top of the water tank 20. No disassembly connection structure (such as snap-fit ​​or locking connections) is required between the housing 10 and the water tank 20. Thus, when cleaning the water tank 20, simply lifting the housing 10 easily separates the water tank 20 from the housing 10, making the water tank 20 and humidification component 30 visible to the user, who can then directly place them into a sink or dishwasher for cleaning. During assembly, simply placing the humidification component 30 on the water tank 20 and then covering it with the housing 10 improves the ease of disassembly and assembly of the humidifier 100 for cleaning.

[0044] In some embodiments, the water tank 20 is at least partially connected to the humidification assembly 30. In this way, water overflowing from the humidification assembly 30 can flow into the water tank 20.

[0045] In some embodiments, the humidification component 30 can be detachably disposed in the water tank 20 to facilitate easy disassembly and assembly between the humidification component 30 and the water tank 20.

[0046] Specifically, such as Figure 2 As shown, the water tank 20 may include a tank body 202 and a water tray 201. The water tray 201 is located on top of the tank body 202. The humidifying component 30 or the housing 10 is detachably disposed on the water tray 201, and the water tray 201 provides structural support for the humidifying component 30. The water tray 201 may be provided with water permeable holes to allow water overflowing from the humidifying component 30 to flow back to the water tank 20.

[0047] In some embodiments, the water channel assembly 40 is disposed inside the housing 10 and fixed relative to the housing 10. The water channel assembly 40 is used to transport water in the water tank 20 to the humidification assembly 30. After being wetted, the humidification assembly 30 can provide moisture to the airflow to achieve the humidification function of the humidifier 100.

[0048] In some embodiments, such as Figure 2 As shown, the water circuit assembly 40 may include a heating element 402. The heating element 402 is used to heat the water flow supplied from the water circuit assembly 40 to the humidification assembly 30, and is located outside the water tank 20. The water flow heated by the heating element 402 can be the water flow drawn from the water tank 20 by the water circuit assembly 40 and poured into the humidification assembly 30. If the water tank 20 is placed on top of the humidifier 100, the water in the water tank 20 can flow directly into the water circuit assembly 40, pass through the heating element 402, and then be poured into the humidification assembly 30.

[0049] Unlike related technologies where humidifiers heat the entire tank of water, which consumes a significant amount of energy, this embodiment places the heating element 402 within the water circuit assembly 40 and positions it outside the water tank 20. This allows the heating element 402 to heat only a small amount of water flowing from the tank 20. Compared to related technologies that heat the entire tank, this embodiment significantly reduces the amount of water heated. This reduces energy consumption and allows for a faster heating process, quickly providing the humidification assembly 30 with a suitable temperature of humidifying water. This meets users' immediate humidification needs and improves the humidifier 100's response speed and user experience.

[0050] It should be noted that after the humidifying component 30 reaches its maximum water holding capacity, the overflowing water will flow back into the water tank 20. This gradually increases the temperature of the water in the water tank 20, allowing the heating power of the heating element 402 to gradually decrease, thereby reducing the energy consumption of the humidifier 100. Furthermore, because the water in the water tank 20 is circulated and heated, the water in the tank 20 is in a state of dynamic heat exchange. This makes the heating efficiency of the heating element 402 for the entire tank of water higher than the heating efficiency of heating elements located inside the water tank in other humidifiers, further reducing the energy consumption of the humidifier 100.

[0051] In addition, the heating element 402 is located outside the water tank 20, and the heating element 402 will not be immersed in the water tank 20 for a long time. The separation of the heating element 402 from the water tank 20 further optimizes the water and electricity separation design and improves the safety and reliability of the humidifier 100.

[0052] In some embodiments, the heating element 402 is located in the inner cavity of the humidification assembly 30. The heating element 402 can be further installed in the inner cavity space of the humidification assembly 30 itself without occupying other space of the humidifier 100 or making structural changes to other structural components, so that the humidifier 100 can be further compacted.

[0053] It should be noted that the humidifying component 30 can be a hollow cylindrical structure, with the hollow part being the inner cavity of the humidifying component 30. Airflow is blown into the humidifying component 30 from the air inlet 101, and then enters the inner cavity of the humidifying component 30 through gas-liquid contact with the humidifying component 30.

[0054] Thus, the humidifier 100 provided in this embodiment utilizes the water circuit assembly 40 as the working component for heating the water in the water tank 20. By adding a heating element 402 to the water circuit assembly 40, heating of a small volume of water (part of the water flowing out of the tank) is achieved, significantly improving the response speed and energy efficiency of the humidifier 100. Furthermore, the heating element 402 is located outside the water tank 20, avoiding the safety risks that may arise from prolonged immersion of the heating element 402 in water, thus improving the safety and reliability of the humidifier 100. Simultaneously, the water circuit assembly 40 serves both to supply water to the humidification component 30 and to heat the water, optimizing the structure of the humidifier 100 and allowing for further compactness and miniaturization.

[0055] In some embodiments, such as Figure 2 As shown, the housing 10 includes a partition 103 located within the receiving cavity 10a. The partition 103 divides the receiving cavity 10a into a fan cavity 104 and a humidification cavity 105. The fan cavity 104 is connected to the air outlet 102, and the humidification cavity 105 is connected to the air inlet 101.

[0056] The fan assembly 70 is located in the fan chamber 104 on one side of the partition 103, and the humidification assembly 30 and the water tank 20 are located in the humidification chamber 105 on the other side of the partition 103.

[0057] In some embodiments, such as Figure 2 As shown, the humidifier 100 includes an electrical control box 50, which is disposed in the fan chamber 104. The electrical control box 50 is connected to the fan assembly 70 and the water circuit assembly 40. The electrical control box 50 can supply power to the heating element 402.

[0058] By placing the electrical control box 50 inside the fan cavity 104, the risk of the electrical control box 50 coming into direct contact with water is reduced, thereby reducing the risk of the circuit getting damp or short-circuited and improving the safety and reliability of the humidifier 100.

[0059] In some embodiments, at least a portion of the heating element 402 is configured as a through pipe, so that the heating element 402 can be used not only as a heating component but also as part of a water pipe, simplifying the structure of the water pipe assembly 40. Furthermore, compared to a flat heating element, having at least a through pipe in the heating element 402 increases the heat exchange area between the heating element 402 and the water flow, allowing for the exchange of more heat with the water flow within the pipe per unit time, thus rapidly heating the water flowing into the heating element 402.

[0060] In addition, the tubular heating element 402 can be more stably connected and sealed with the water inlet pipe of the water pump 401, reducing the probability of water overflow.

[0061] In some embodiments, the heating element 402 may be a thermistor heating element.

[0062] Specifically, the heating element 402 can be a positive temperature coefficient (PTC) thermistor.

[0063] In some embodiments, such as Figure 3 As shown, a flame-retardant insulation layer 403 may be provided on the outside of the heating element 402. The flame-retardant insulation layer 403 can surround the heating element 402 to improve the heat insulation effect of the heating element 402. The flame-retardant insulation layer 403 can be made of materials such as rock wool, foam glass, and polyurethane.

[0064] In some embodiments, a protective layer may be provided inside the heating element 402. The protective layer can isolate the water flow from the heating element 402 to prevent the heating element 402 from being corroded by prolonged contact with water. Specifically, the protective layer can be connected to the water pump 401, and the heating element 402 is disposed outside the protective layer.

[0065] The protective layer is made of plastic or silicone. It can be a tube made of high-temperature resistant plastic or silicone. The plastic can be polyimide, polyphenylene sulfide, polytetrafluoroethylene, etc. The silicone can be high-temperature silicone, high-temperature platinum silicone, high-temperature fluorosilicone, etc.

[0066] In some embodiments, such as Figure 2As shown, the water circuit assembly 40 may include a water pump 401. The top of the water tank 20 is perforated to allow the water pump 401 to extend into the water tank 20 and extract water from it. The water pump 401 is fixed relative to the housing 10 and can move synchronously with it. When the housing 10 is fitted over the water tank 20, the water pump 401 of the water circuit assembly 40 can extend into the water tank 20 to extract water. The water pump 401 is in fluid communication with the heating element 402 and is located on the water inlet side of the heating element 402.

[0067] In some embodiments, such as Figure 3 and Figure 4 As shown, the water circuit assembly 40 includes a first housing 404 and a second housing 405. A water pump 401 is disposed in the first housing 404, and a heating element 402 is disposed in the second housing 405.

[0068] In some embodiments, such as Figure 3 and Figure 4 As shown, the first housing 404 and the second housing 405 are arranged along the height direction of the humidifier 100 to reduce the occupation of the internal space of the humidification component 30 caused by the first housing 404 and the second housing 405 being stacked in the horizontal direction, so as to ensure that the humidification component 30 has more airflow.

[0069] Specifically, the second housing 405 is located above the first housing 404.

[0070] In some embodiments, such as Figure 4 As shown, a wire-passing area 407 is formed on the top of the second housing 405. A second cover 408 is provided on the second housing 405, which covers the wire-passing area 407. The wire-passing area 407 is used to provide electrical connection wires connecting the electrical control box 50 and the heating element 402.

[0071] In some embodiments, such as Figure 2 As shown, the water circuit assembly 40 includes a water level sensor 409. The water level sensor 409 is used to detect the water level in the water tank 20. The water level sensor 409 can be disposed in the second housing 405 and located on the side of the heating element 402. The water level sensor 409 can be electrically connected to the control device of the humidifier 100. The water level value acquired by the water level sensor 409 is used by the control device of the humidifier 100 to control the operation of the heating element 402.

[0072] In some embodiments, the water level sensor 409 includes a float, a magnet, and a Hall sensor. The float is movably mounted on the second housing 405 in the vertical direction. The magnet is fixed to the float, and the Hall sensor is fixed to the second housing 405. The magnet and the Hall sensor cooperate to detect the water level in the water tank 20.

[0073] A float with a fixed magnet is movably mounted on the second housing 405 and can float freely on the water surface. A Hall sensor converts the changing magnetic field into a change in output voltage. The Hall sensor can be set at a predetermined position in the water tank 20. As the water level in the water tank 20 changes, the magnet moves up and down with the float. The Hall sensor can detect the change in the magnetic field of the magnet, thereby detecting the position of the float and sending an electrical signal indicating the float's position to the control device.

[0074] When the control device determines that the water level in the water tank 20 is sufficient, the control device in the electrical control box 50 controls the heating element 402 to operate and heat the water in the heating element 402. When the control device determines that the water level in the water tank 20 is low or there is no water, the control device controls the heating element 402 to stop operating, reducing the risk of fire caused by dry burning of the heating element 402 and improving the safety and reliability of the humidifier 100.

[0075] In some embodiments, such as Figure 5 As shown, the central region of the partition 103 has a hollow section 1031, and the water channel assembly 40 is connected to the hollow section 1031.

[0076] In some embodiments, at least a portion of the water path assembly 40 extends into the inner cavity of the humidification assembly 30. Since the humidification assembly 30 is typically located at the center of the humidifier 100, that is, the water path assembly 40 is located in the central region of the humidifier 100. Because the water path assembly 40 has a certain weight, if the water path assembly 40 is offset, it will cause the center of gravity of the humidifier 100 to shift. By placing the water path assembly 40 in the central region of the humidifier 100, the overall center of gravity of the humidifier 100 will be more balanced and stable, and it will not be easy for it to tilt or tip over.

[0077] Furthermore, the water circuit assembly 40 can extend further into the water tank 20 from the inner cavity of the humidifying assembly 30, and draw water from the water tank 20 and spray it into the humidifying assembly 30. Unlike related technologies where the humidifying water circuit assembly is located on the outer periphery of the humidifying assembly, i.e., between the humidifying assembly and the air inlet, in this embodiment, the water circuit assembly 40 is positioned in the central area of ​​the partition 103, thus not obstructing the air inlet 101, thereby increasing the flow rate of airflow from the air inlet 101 into the airflow channel.

[0078] In some embodiments, such as Figures 2 to 5 As shown, the humidifier 100 includes a ventilation grille 80. The ventilation grille 80 is disposed around the water channel assembly 40 and at the air inlet 703 of the fan assembly 70.

[0079] It is understandable that, due to the negative pressure generated by the impeller 702 in the fan assembly 70 during rotation, the fan assembly 70 and the humidification assembly 30 are located on opposite sides of the partition 103. The ventilation grille 80 is connected to the air inlet 703 of the fan assembly 70, meaning the ventilation grille 80 is located in the area with strong negative pressure at the air inlet of the fan assembly 70. The air pressure generated by the negative pressure suction is concentrated in the ventilation grille 80. Thus, the ventilation grille 80 can effectively guide the airflow towards the fan assembly 70, allowing the humidified airflow to enter the fan assembly 70 at a higher speed and pressure. The fan assembly 70 further accelerates and pressurizes the airflow, enabling the humidified airflow to exit the humidifier 100 from the air outlet 102 with a greater head and more uniform diffusion effect, thereby improving the humidification range of the humidifier 100 and the uniformity of indoor air humidity.

[0080] In some embodiments, a connection structure (such as snap-fit ​​or locking) that requires disassembly may not be provided between the housing 10 and the water tank 20. This allows for easy separation of the water tank 20 from the housing 10 simply by lifting the housing 10, making the water tank 20 and humidification component 30 visible to the user, who can then directly place them into a sink or dishwasher for cleaning. During assembly, the humidification component 30 is simply placed on the water tank 20, and the housing 10 is then placed over it, improving the ease of disassembly and assembly of the humidifier 100 for cleaning.

[0081] Furthermore, when it is necessary to clean the water tank 20 and the humidification component 30, the water circuit component 40 can be separated from the water tank 20 by lifting the housing 10 upwards. As long as the shape and size of the air vent are properly set, the ventilation grille 80 located at the air inlet 703 of the fan component 70 can block the user's fingers, preventing the user's fingers from accidentally sticking into the fan component 70, thereby improving the safety of using the humidifier 100.

[0082] In some embodiments, the ventilation grille 80 can be integrally formed with the water channel assembly 40. Specifically, the ventilation grille 80 can be integrally formed with the second housing 405. In this way, the water channel assembly 40 and the ventilation grille 80 can be assembled together, simplifying the assembly process within the humidifier 100.

[0083] In some embodiments, such as Figure 3 and Figure 4 As shown, the ventilation grille 80 surrounds the outer periphery of the second housing 405. The ventilation grille 80 can provide comprehensive ventilation along the circumference of the humidifier 100, avoiding vibration or noise caused by uneven airflow distribution and improving the user experience.

[0084] In some embodiments, the ventilation grille 80 is connected to the air inlet of the partition 103 and the fan assembly 70, respectively.

[0085] The fan assembly 70 may include a fan housing 701. A ventilation grille 80 may be connected to the air inlet of the fan housing 701 to increase the airflow rate entering the fan assembly 70 from the ventilation grille 80 and reduce airflow loss. The ventilation grille 80 may be connected to both the partition 103 and the fan assembly 70 to further reduce airflow loss when airflow enters the fan assembly 70.

[0086] In some embodiments, such as Figure 4 and Figure 5 As shown, the water circuit assembly 40 also includes a water outlet pipe 410, which is connected to the heating element 402. The water outlet pipe 410 has a first water outlet 4101. The water flowing out of the first water outlet 4101 is water heated by the heating element 402. Along the height direction, the first water outlet 4101 corresponds to the top of the humidification assembly 30, so as to directly inject heated water into the humidification assembly 30.

[0087] In some embodiments, the water outlet pipe 410 is located on the side of the partition 103 away from the humidification assembly 30, and the first water outlet 4101 of the water outlet pipe 410 is connected to the water inlet 1032.

[0088] The water outlet pipe 410 is connected to the heating element 402 to guide water flow to the water inlet 1032 to supply water to the humidification assembly 30. The water outlet pipe 410 can be located above the partition 103, that is, the water outlet pipe 410 is located inside the fan cavity 104 and connected to the water inlet 1032. Along the height direction of the humidifier 100, the water inlet 1032 is correspondingly arranged with the humidification assembly 30 so that the water flowing out of the water inlet 1032 can directly spray into the humidification assembly 30.

[0089] In some embodiments, such as Figure 5 As shown, the humidifier 100 also includes a temperature sensor 60. The temperature sensor 60 can be set at the first water outlet 4101 to detect the temperature of the water flowing out of the water outlet pipe 410.

[0090] Specifically, a temperature sensor 60 is disposed on the partition 103 and extends at least partially into the permeable port 1032 / first outlet 4101 to detect the temperature of the water flowing from the outlet pipe 410 of the water circuit assembly 40. The control device integrated in the control box 50 can control the heating temperature of the heating element 402 in the water circuit assembly 40 according to the detected temperature value. When the temperature sensor 60 detects that the water temperature is lower than a preset threshold, the control device integrated in the control box 50 will dynamically adjust the power of the heating element 402 in the water circuit assembly 40 to increase the water temperature to the target temperature.

[0091] For example, if the temperature sensor 60 detects that the water temperature is 15°C and the target temperature is 30°C, the control device will control the heating power of the heating element 402 through an algorithm until the water temperature stabilizes at 30°C.
