Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a heater. Background Technology

[0002] Heaters are common heating devices widely used for indoor heating. However, prolonged operation of heaters can lead to dry indoor air, which can affect user comfort and even pose a fire hazard. To address this issue, humidifiers are typically incorporated into heaters. Existing heaters with humidification functions usually use electronic oscillators that atomize water through vibration, dispersing it into the air to humidify it.

[0003] However, electronic oscillators atomize water through vibration, forming relatively large water mists. The distance the water mist spreads is relatively small, leading to uneven humidification. They may also wet the area near the heater and may even carry impurities from the water, affecting air quality. Utility Model Content

[0004] In view of this, the present invention provides a heater that at least solves the problem of uneven humidification caused by existing heaters using atomization to humidify.

[0005] This application provides a heater, including a housing and a fan, a heating element, and a humidifying element respectively installed on the housing. The housing has an air duct and an air inlet and an air outlet respectively connected to the air duct. The heating element is located in the air duct, and the humidifying element is located on the side of the heating element away from the air inlet. The fan is used to drive airflow to flow in from the air inlet, and after passing through the heating element and the humidifying element in sequence, it flows out from the air outlet, so as to humidify the heated airflow through the humidifying element.

[0006] In some embodiments, the humidification assembly includes a water tank and a water-absorbing element located outside the water tank, the water-absorbing element being located within the air duct.

[0007] In some embodiments, a water trough is provided on the outside of the water tank, the water trough extends circumferentially along the water tank, and the water-absorbing part is located inside the water trough and surrounds the outer periphery of the water tank.

[0008] In some embodiments, the water tank is further provided with a water storage cavity and a water inlet connecting the water storage cavity and the water tank, wherein the top of the water inlet is higher than the bottom of the water tank but not higher than the top of the water tank.

[0009] In some embodiments, the water tank is provided with a partition, which cooperates with the water tank to form a water outlet channel. The water outlet channel is connected to the water inlet. The partition is provided with a water outlet that connects the water storage chamber and the water outlet channel. The top of the water outlet is not higher than the bottom of the water inlet.

[0010] In some embodiments, the separator includes a substrate and an extension located on one side of the substrate, the water outlet channel is located on the side of the substrate near the extension and surrounds the outer periphery of the extension, the water storage cavity includes a first cavity located on the side of the substrate away from the extension and a second cavity located inside the extension, and the water outlet is provided on the extension and communicates with the second cavity.

[0011] In some embodiments, the water tank is provided with a water inlet communicating with the first cavity, and the humidification assembly further includes a piston structure that is movably coupled to the water tank. The piston structure has a use state and a water filling state. In the use state, the piston structure seals the water inlet and opens the water outlet. In the water filling state, the piston structure seals the water outlet and opens the water inlet.

[0012] In some embodiments, the piston structure includes a first piston movably disposed in the water tank, a second piston movably disposed in the extension, and a connecting rod connecting the first piston and the second piston, wherein the distance between the first piston and the second piston is greater than the distance between the water inlet and the water outlet.

[0013] In some embodiments, the housing is cylindrical, the fan and the humidification component are both located inside the housing, the heating component is located between the fan and the humidification component, the air outlet includes a first air outlet located on one axial side of the housing and a second air outlet that radially penetrates the housing, and the humidification component is located between the first air outlet and the second air outlet.

[0014] In some embodiments, the heating component includes a plurality of heat-conducting sheets and a heat-conducting connector, wherein the plurality of heat-conducting sheets are connected by the heat-conducting connector to form a ring structure, and the plurality of heat-conducting sheets are spaced apart.

[0015] Compared with the prior art, the heater provided by this utility model has at least the following beneficial effects:

[0016] Outside air enters the duct through the air inlet under the action of the fan and flows along the extension direction of the duct. During the flow, the air first passes through the heating element, where it exchanges heat and its temperature rises. The heated air then passes through the humidification element, where the water is heated by the air and evaporates into water vapor. The water vapor flows with the air, humidifying the passing air and creating a warm and humid airflow. This achieves both heating and humidification effects. Since the humidification element forms water vapor through evaporation, compared to atomization to form water mist, water vapor is lighter and more fluid, making it easier to flow with the airflow. This results in more even humidification, avoids wetting the area near the heater, and reduces the risk of air pollution from impurities carried out of the water. Furthermore, evaporative humidification does not require electricity, which helps reduce the power consumption of the heater. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] It should be noted that all directional indicators (such as up, down, left, right, front, back, inside, outside, top, bottom, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship between the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0027] It should also be noted that when a component is referred to as "fixed to" or "set on" another component, the component may be directly on the other component or there may be an intervening component present. When a component is referred to as "connected to" another component, it may be directly connected to the other component or there may be an intervening component present.

[0028] Please see Figures 1 to 7This utility model provides a heater 10, including a housing 12, a fan 14, a heating element 16, and a humidifying element 18. The housing 12 is provided with an air duct 20 and an air inlet 22 and an air outlet 24 respectively connected to the air duct 20. The fan 14 is installed on the housing 12 to drive outside air into the air duct 20 through the air inlet 22 and flow towards the air outlet 24, and finally exhaust it from the air outlet 24 to the outside of the heater 10. The heating element 16 is located inside the air duct 20. As the airflow flows from the air inlet 22 to the air outlet 24, it passes through the heating element 16, thereby exchanging heat with the heating element 16 and raising the temperature of the airflow. The humidifying component 18 is located on the side of the heating component 16 away from the air inlet 22 and is correspondingly arranged with the air outlet 24. This allows the fan 14 to drive the airflow through the heating component 16 and the humidifying component 18 sequentially. Specifically, the fan 14 drives the airflow to first pass through the heating component 16 and then through the humidifying component 18, where the heated airflow is humidified. When the airflow heated by the heating component 16 passes through the humidifying component 18, it exchanges heat with the water in the humidifying component 18, causing the water in the humidifying component 18 to evaporate and form water vapor. The water vapor mixes with the airflow and flows together, forming a warm and humid airflow to achieve the effects of heating and humidification. Since the humidifying component 18 achieves humidification by absorbing heat and evaporating water to form water vapor, compared with water atomization humidification, water vapor is lighter and more fluid, making it easier to flow with the airflow and with a larger flow range, resulting in a more even humidification effect. This avoids wetting the area near the heater 10 and also reduces the risk of air pollution caused by impurities carried out of the water. Furthermore, humidification by evaporation does not require electricity, which helps reduce the power consumption of the heater 10.

[0029] Understandably, the fan 14 and the humidification component 18 can be located inside the housing 12 or outside the housing 12. In this embodiment, both the fan 14 and the humidification component 18 are inside the housing 12, and the heating component 16 is located between the fan 14 and the humidification component 18, and is spaced apart from both the fan 14 and the humidification component 18. By placing the fan 14 and the humidification component 18 inside the housing 12, not only can the fan 14 and the humidification component 18 be protected, but the overall structure is also more compact, the overall volume is reduced, and the obtrusiveness of the fan 14 and the humidification component 18 is minimized. Furthermore, warm and humid air can be formed inside the housing 12 before being discharged from the air outlet 24, allowing the airflow to fully contact the humidification component 18, which is beneficial for enhancing the humidification effect.

[0030] In an alternative example, the housing 12 is cylindrical, and the air duct 20 extends along the axial direction of the housing 12, making the housing 12 a hollow cylindrical structure. The fan 14 is disposed near the bottom of the housing 12, the humidification component 18 is disposed near the top of the housing 12, and the heating component 16 is located in the middle of the housing 12.

[0031] The fan 14 can be an axial flow fan or a mixed flow fan. The axial end of the housing 12 is provided with an air outlet 24. The airflow generated by the fan 14 flows along the axial direction of the housing 12 under the guidance of the cylindrical housing 12 and is blown out from the air outlet 24 at the axial end of the housing 12.

[0032] The air inlet 22 is located near the bottom of the housing 12 and extends radially through the housing 12. The air outlet 24 includes a first air outlet 26 and a second air outlet 28. The first air outlet 26 is located on one axial side of the housing 12, and the second air outlet 28 extends radially through the housing 12. The humidification component 18 is located between the first air outlet 26 and the second air outlet 28. After the airflow passes through the heating component 16, part of the airflow flows towards the first air outlet 26, is humidified by the humidification component 18, and is then blown out from the first air outlet 26. The other part of the airflow does not pass through the humidification component 18 and is blown directly out from the second air outlet 28. That is, the airflow that passes through the humidification component 18 is discharged axially along the housing 12, and the airflow that does not pass through the humidification component 18 is discharged radially along the housing 12, creating the effect of airflow in different directions and positions to increase the coverage of the warm air.

[0033] In this embodiment, the air inlet 22 and the second air outlet 28 are each composed of multiple through holes with relatively small diameters. The multiple through holes of the air inlet 22 and the second air outlet 28 are arranged at intervals along the axial and circumferential directions of the housing 12, forming a grille-like shape, thus creating a 360° annular air intake and annular air outlet effect. The top of the housing 12 is open, and this opening constitutes the first air outlet 26.

[0034] The housing 12 includes a first housing 30 and a second housing 32 arranged axially. The first housing 30 is located below the second housing 32. The fan 14 and the heating element 16 are located inside the first housing 30. The air inlet 22 is located in the first housing 30, the humidifying element 18 is located inside the second housing 32, and the air outlet 24 is located in the second housing 32. By configuring the housing 12 into two parts, the first housing 30 and the second housing 32, during assembly, the first housing 30 and the second housing 32 can be separated first, then the fan 14 and the heating element 16 can be installed into the first housing 30, the humidifying element 18 can be installed into the second housing 32, and then the first housing 30 and the second housing 32 can be connected. This reduces the installation difficulty of the fan 14, the humidifying element 18, and the heating element 16.

[0035] In one embodiment, the humidification assembly 18 includes a water tank 34 and a water-absorbing component 36 located outside the water tank 34. The water tank 34 stores water, and the water-absorbing component 36 absorbs the water stored in the water tank 34 and locks the absorbed water inside. The water-absorbing component 36 is located inside the air duct 20. After the airflow is heated by the heating component 16, it passes through the water-absorbing component 36 to evaporate the water absorbed by the water-absorbing component 36. The arrangement of the water-absorbing component 36 can increase the contact area between the airflow and the water, enhance the evaporation effect of the water, and thus improve the humidification effect.

[0036] Preferably, the water-absorbing component 36 is detachably installed to the water tank 34. When the water-absorbing component 36 is damaged or the water absorption effect deteriorates due to long-term use, the user can replace the water-absorbing component 36 to ensure the humidification effect.

[0037] The water-absorbing component 36 can be a wet curtain, foam, or sponge, as long as it has both water-absorbing and water-locking effects. In this embodiment, the water-absorbing component 36 is a wet curtain with a honeycomb-like shape inside and a large surface area to facilitate rapid water diffusion and evaporation, thus ensuring the humidification effect.

[0038] The specific method by which the water-absorbing component 36 absorbs water stored in the water tank 34 is not limited. For example, the water tank 34 can be placed inside the air duct 20, allowing the water-absorbing component 36 to directly contact the water stored in the water tank 34. Alternatively, the water-absorbing component 36 can indirectly absorb water stored in the water tank 34 through an intermediate component. In this case, the water tank 34 can be located inside or outside the air duct 20. In this embodiment, both the water tank 34 and the water-absorbing component 36 are located inside the air duct 20. The water tank 34 is connected to the housing 12, and the water-absorbing component 36 surrounds the outer periphery of the water tank 34 to further increase the contact area with the airflow and enhance the humidification effect.

[0039] A water tank 34 has a water trough 38 on its outer side, which extends circumferentially along the water tank 34 to form an annular groove. The water suction member 36 is partially located inside the water trough 38 and surrounds the outer periphery of the water tank 34. The water trough 38 can be used to store water, and the water suction member 36 is partially located inside the water trough 38 and directly contacts the water in the water trough 38, thereby absorbing water from the water trough 38.

[0040] The water tank 34 is also provided with a water storage cavity 40 and a water inlet 42. The water storage cavity 40 is located inside the water tank 34, and the water tank 38 is located outside the water tank 34 and surrounds the outer periphery of the water storage cavity 40. The water inlet 42 connects the water storage cavity 40 and the water tank 38. The top of the water inlet 42 is higher than the bottom of the water tank 38 but not higher than the top of the water tank 38. The water storage chamber 40 inside the water tank 34 can be used to store water. When the water level in the water storage chamber 40 is higher than the water inlet 42, during the use of the heater 10, the water suction component 36 continuously draws water from the water tank 38 for evaporative humidification. After the water level in the water tank 38 is lower than the top of the water inlet 42, the water in the water storage chamber 40 can automatically flow into the water tank 38 through the water inlet 42, forming an automatic water replenishment effect. Moreover, the top of the water inlet 42 is not higher than the top of the water tank 38, which can prevent the water in the water tank 38 from overflowing due to the water inlet 42 being higher than the water tank 38.

[0041] The specific number of water inlets 42 is not limited; there can be one or more. When there are multiple water inlets 42, they are arranged at intervals along the circumference of the water storage cavity 40, and each water inlet 42 is connected to the water storage cavity 40 and the water tank 38.

[0042] In an optional example, the water tank 34 includes a body 44 and an end cap 46 located at the bottom of the body 44. The bottom of the body 44 is open and fits against the end cap 46. The water storage cavity 40 is located inside the body 44 and the end cap 46. The water inlet 42 is located in the body 44. The outer periphery of the end cap 46 is provided with an upwardly protruding enclosure 48. The enclosure 48 surrounds the outer periphery of the body 44 and is radially spaced a certain distance from the body 44. The water tank 38 is located between the body 44 and the enclosure 48. The top of the water tank 38 is the top of the enclosure 48. The water suction member 36 surrounds the outer periphery of the body 44 and its bottom end extends into the water tank 38.

[0043] In one embodiment, the humidification assembly 18 further includes a partition 50 located inside the water tank 34. The partition 50 and the water tank 34 cooperate to form a water outlet channel 51. The water outlet channel 51 is connected to the water inlet 42. The partition 50 is provided with a water outlet 64 that connects the water storage chamber 40 and the water outlet channel 51. Water in the water storage chamber 40 can flow into the water outlet channel 51 through the water outlet 64, and then flow into the water tank 38 from the water outlet channel 51 through the water inlet 42, thereby replenishing the water tank 38 with water. The top of the outlet 64 is not higher than the bottom of the inlet 42. When water in the storage chamber 40 flows into the water tank 38 and submerges the inlet 42, the inside of the water tank 34 becomes sealed. Water in the storage chamber 40 stops flowing through the outlet 64 to the outlet channel 51, and water in the outlet channel 51 stops flowing into the water tank 38 through the inlet 42, stopping the replenishment of water to the water tank 38. When some water in the water tank 38 is consumed and partially exposed at the outlet 64, outside air can... Water enters the water tank 34 through the water inlet 42. Water in the outlet channel 51 flows into the water tank 38 through the water inlet 42. Water in the storage chamber 40 flows into the outlet channel 51 through the water outlet 64, replenishing the water tank 38 again until the water in the water tank 38 overflows the water inlet 42, thus automatically replenishing the water tank 38. At the same time, water in the storage chamber 40 flows into the water tank 38 through the water outlet 64 and the outlet channel 51, thus automatically replenishing the water and preventing water from overflowing from the water tank 38.

[0044] The separator 50 includes a substrate 58 and an extension 60 located on one side of the substrate 58. A water outlet channel 51 is located on the side of the substrate 58 near the extension 60 and surrounds the outer periphery of the extension 60. The water storage chamber 40 includes a first chamber 52 and a second chamber 54, located on opposite sides of the substrate 58. The first chamber 52 is located on the side of the substrate 58 away from the extension 60, and the second chamber 54 is located on the side of the substrate 58 near the extension 60. A connecting port 56 is provided on the substrate 58, and the first chamber 52 and the second chamber 54 are connected through the connecting port 56. The extension 60 is hollow, and the second chamber 54 is located inside the extension 60. A water outlet 64 is provided through the extension 60, and the second chamber 54 is connected to the water outlet channel 51 through the water outlet 64.

[0045] The specific number of outlets 64 is not limited; there can be one or more. When there are multiple outlets 64, the multiple outlets 64 are arranged at intervals along the circumference of the extension 60.

[0046] In one embodiment, the water tank 34 is provided with a water inlet 66 that communicates with the water storage chamber 40. The water inlet 66 is located at the top of the water tank 34 and communicates with the first chamber 52. The user can add water to the water storage chamber 40 through the water inlet 66.

[0047] The humidification assembly 18 also includes a piston structure 68 that is movably coupled to the water tank 34. The piston structure 68 has a use state and a water filling state, and the piston structure 68 can move relative to the water tank 34 to switch between the use state and the water filling state.

[0048] In operation, the piston structure 68 seals the water inlet 66 and opens the water outlet 64. At this time, the water inlet 66 does not affect the internal pressure of the water storage chamber 40. Water in the water storage chamber 40 can flow into the water tank 38 through the water inlet 42, providing a water replenishment effect while preventing overflow. In the water-filling state, the piston structure 68 seals the water outlet 64 and opens the water inlet 66. The user can then add water to the water storage chamber 40 through the water inlet 66. The water outlet 64 is sealed by the piston structure 68 to prevent water from entering the second chamber 54 through the water outlet 64 during the water-filling process, thus preventing water from overflowing from the water tank 38.

[0049] The piston structure 68 includes a first piston 70 movably disposed in the water tank 34, a second piston 72 movably disposed within the extension 60, and a connecting rod 74 connecting the first piston 70 and the second piston 72. The connecting rod 74 is fixed relative to the first piston 70 and the second piston 72, and the distance between the first piston 70 and the second piston 72 is greater than the distance between the water inlet 66 and the water outlet 64. The length of the extension 60 is greater than the thickness of the second piston 72. When the connecting rod 74 moves up and down, it drives the first piston 70 and the second piston 72 to move together. The first piston 70 moves relative to the water inlet 66, thereby opening or sealing the water inlet 66. The second piston 72 slides within the extension 60 and moves relative to the water outlet 64, thereby sealing or opening the water outlet 64. The top of the connecting rod 74 protrudes from the outside of the water tank 34 for user operation.

[0050] In an optional example, in the use state, the second piston 72 is located below the water outlet 64, and in the water filling state, the second piston 72 is located above the water outlet 64. That is, the piston structure 68 can be switched from the use state to the water filling state by moving the connecting rod 74 upward, and the piston structure 68 can be switched from the water filling state to the use state by moving the connecting rod 74 downward.

[0051] The top of the water tank 34 is provided with a mounting position 76. The first piston 70 is movably located in the mounting position 76. The water inlet 66 connects the mounting position 76 and the water storage chamber 40. In the use state, the first piston 70 is located in the mounting position 76 and covers the water inlet 66, which has the effect of sealing the water inlet 66. In the water filling state, the first piston 70 is withdrawn from the mounting position 76, opening the mounting position 76 and the water inlet 66.

[0052] Optionally, the outer periphery of the first piston 70 and the second piston 72 are respectively provided with sealing rings. The first piston 70 is sealed to the inner wall of the mounting position 76 through the sealing ring on its outer periphery, and the second piston 72 is sealed to the inner wall of the extension 60 through the sealing ring on its outer periphery.

[0053] In one embodiment, the heating component 16 includes a plurality of heat-conducting plates 80 and a heat-conducting connector 82 connecting the plurality of heat-conducting plates 80. The plurality of heat-conducting plates 80 are connected by the heat-conducting connector 82 to form a ring structure. The plurality of heat-conducting plates 80 are spaced apart, and airflow can flow through the gaps between adjacent heat-conducting plates 80, which can increase the contact area between the heating component 16 and the airflow, enhance the heating effect on the airflow, and at the same time reduce the wind resistance of the heating component 16 to the airflow, making the airflow smoother and helping to reduce noise.

[0054] Optionally, the heat-conducting plate 80 is made of aluminum. Aluminum not only has the function of conducting heat, but also has a low density, so it can be made into a thinner plate, which is beneficial to increase the gap between adjacent heat-conducting plates 80 to reduce wind resistance and noise.

[0055] The heating method of the heating component 16 is not limited. For example, it can be achieved by setting a heating element, such as a heating plate, and contacting the heating element with the heat-conducting connector 82 or the heat-conducting plate 80. The heat generated by the heating element can be transferred to each heat-conducting plate 80 by the heat-conducting connector 82. Alternatively, the heat-conducting connector 82 can be set as a structure similar to a resistance wire, and the heat generated by the heat-conducting connector 82 can be transferred to each heat-conducting plate 80.

[0056] In an alternative example, a support member 84 is provided inside the housing 12, the support member 84 is fixed relative to the housing 12, the heating component 16 is installed on the top of the support member 84, and the fan 14 is installed on the bottom of the support member 84.

[0057] The housing 12 is also provided with a mounting bracket 86, which is located above the support member 84 and fixed relative to the support member 84. The heating component 16 is indirectly installed to the support member 84 through the mounting bracket 86, and the humidifying component 18 is indirectly installed to the top of the mounting bracket 86 through an intermediate component.

[0058] The mounting bracket 86 includes an inner frame 88, an outer frame 90 spaced around the outer periphery of the inner frame 88, and a connecting portion 92 connecting the inner frame 88 and the outer frame 90. A ring structure formed by multiple heat-conducting plates 80 surrounds the outer side of the inner frame 88, thereby housing the heating component 16 in the gap between the inner frame 88 and the outer frame 90.

[0059] Optionally, the outer frame 90 can be made of heat-insulating material, that is, the outer frame 90 is a heat-insulating component. The heating component 16 generates heat and the overall temperature is relatively high. The outer frame 90 surrounds the outer periphery of the heating component 16 and is located between the heating component 16 and the housing 12. Therefore, it can prevent the heat on the heating component 16 from being transferred to the housing 12, and prevent the part of the housing 12 near the heating component 16 from getting too hot and burning the user.

[0060] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
