Description

Technical Field

[0001] This utility model relates to a humidification component and a humidity control system. Background Technology

[0002] The heating water tank heats the water inside using heating elements, raising the water temperature to, for example, boiling. This increased temperature generates steam, thus humidifying the water. During use, scale may form inside the heating water tank, requiring periodic drainage and cleaning. Alternatively, when humidification is not needed, the water in the heating water tank should be drained to prevent bacterial growth or excessive scale buildup. However, the water in the heating water tank can become excessively hot; direct drainage can damage components in the drainage path and external drain pipes due to high temperatures, reducing their reliability and lifespan. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a humidification component that effectively reduces the water temperature at the outlet of the drain pan, delays the aging of the detection element and external pipeline materials, and reduces the risk of high-temperature damage to the detection element and external pipeline.

[0004] A humidifying component according to an embodiment of the present invention includes: a housing; a water inlet tank disposed within the housing, the water inlet tank being connected to an external water source via a water inlet pipe, the water inlet pipe being provided with a water inlet valve, and a first pipe section being provided on the bottom or side wall of the water inlet tank; a heating water tank disposed within the housing, the water inlet tank being connected to the heating water tank via a water supply pipe to supply water to the heating water tank, the heating water tank being provided with a heating element, the heating water tank being provided with a steam outlet, and a second pipe section being provided at the lower part of the heating water tank; a drain tray disposed within the housing, the drain tray having a water outlet, and a detection element being provided at the water outlet; and a third pipe section, the ends of the first pipe section, the second pipe section, and the starting end of the third pipe section being configured to connect to drain water to a drain port of the third pipe section, the third pipe section being provided with a drain valve, and the third pipe section being configured to drain water to the drain tray through the drain port.

[0005] According to the humidification component of this utility model embodiment, the third pipe section can be used to mix the hot water discharged from the heating water tank and the cold water discharged from the inlet water tank, which can reduce the temperature of the water discharged to the drain pan, prevent the drain pan, detection element and external pipeline from being damaged by high temperature, delay the aging of their materials, improve the reliability of the humidification component, and achieve cooling during the drainage process of the heating water tank without waiting for the hot water to cool down naturally, thereby improving drainage efficiency.

[0006] According to some embodiments of the humidification assembly of this utility model, the drain tray has opposing first and second side plates, the water outlet is disposed near the first side plate, and the drain port is disposed near the second side plate. The mixed water discharged into the drain tray via the third pipe section can flow as far as possible within the drain tray before being discharged from the water outlet, allowing the mixed water to be further cooled within the drain tray, further reducing the risk of aging and high-temperature damage to the detection element and external piping.

[0007] According to some embodiments of the humidification assembly of this utility model, the housing has an inspection port, and at least the projection of the heating element on the wall surface where the inspection port is located overlaps with the inspection port. The inspection port allows for inspection, disassembly, and other operations on the heating element, facilitating maintenance of the heating element.

[0008] According to some embodiments of the humidification assembly of this utility model, the bottom wall or side wall of the heating water tank is provided with a drain outlet, the drain outlet is connected to the second pipe section, and a filter element is provided at the drain outlet. The filter element can filter the water discharged from the heating water tank, making it difficult for scale in the heating water tank to enter the drain outlet, which helps to ensure the service life of components such as drain valves installed in the drainage path.

[0009] According to some embodiments of the humidification assembly of this utility model, the first pipe segment and the second pipe segment constitute the water supply pipeline. The humidification assembly eliminates the need for a separate water supply pipeline to supply water to the heating water tank, simplifying the piping and facilitating miniaturization.

[0010] This utility model also proposes a humidification component.

[0011] A humidification assembly according to an embodiment of the present invention includes: a housing; a water inlet tank disposed within the housing, the water inlet tank being connected to an external water source via a water inlet pipe, the water inlet pipe being provided with a water inlet valve; a heating water tank disposed within the housing, the water inlet tank being connected to the heating water tank via a water supply pipe to supply water to the heating water tank, the heating water tank being provided with a heating element, the heating water tank being provided with a steam outlet, the lower part of the heating water tank being provided with a first drain pipe, the first drain pipe being provided with a first control valve; and a drain pan disposed within the housing, the drain pan having a water outlet, the water outlet being provided with a detection element; wherein, the first drain pipe is configured to drain water to the drain pan through its outlet, the drain pan having opposing first and second side plates, the water outlet being disposed near the first side plate, and the outlet of the first drain pipe being disposed near the second side plate.

[0012] According to the humidification component of this utility model embodiment, the outlet of the first drain pipe and the outlet of the drain pan are respectively located close to the first side plate and the second side plate, so that the outlet of the drain pan and the outlet of the first drain pipe are as far apart as possible in the arrangement direction of the first side plate and the second side plate. After the first drain pipe discharges hot water from the heating water tank to the drain pan, the hot water can flow as far as possible in the drain pan before being discharged from the outlet, so that the hot water is cooled down as much as possible in the drain pan, thereby reducing the temperature of the water in contact with the detection element and the external pipeline, delaying the aging of the materials of the detection element and the external pipeline, and reducing the risk of high temperature damage to the detection element and the external pipeline.

[0013] According to some embodiments of the humidification assembly of this utility model, the bottom or side wall of the heating water tank is provided with a drain outlet, which is connected to the first drain pipe. A filter element is provided at the drain outlet. The filter element can filter the water discharged from the heating water tank, making it difficult for scale in the heating water tank to enter the drain outlet, which helps to ensure the life of components such as the first control valve set in the drain path.

[0014] According to some embodiments of the humidification assembly of this utility model, the bottom or side wall of the water inlet tank is provided with a second drain pipe. The second drain pipe is provided with a second control valve. The second drain pipe is configured to drain water to the drain pan through its outlet. The drain pan has a mixing flow path located between the outlet of the first drain pipe and the water outlet. The outlet of the second drain pipe is located between the outlet of the first drain pipe and the water outlet, and the outlet of the second drain pipe is connected to the mixing flow path. The cold water discharged from the second drain pipe can mix with the hot water discharged from the first drain pipe in the mixing flow path to obtain mixed water with a lower temperature. The mixed water continues to flow along the mixing flow path to the water outlet, thereby further reducing the temperature of the water discharged at the water outlet and further reducing the risk of aging and high-temperature damage to the detection element and external pipeline.

[0015] According to some embodiments of the humidification assembly of this utility model, there are multiple heating water tanks. The inlet water tank is connected to each of the multiple heating water tanks via a water supply pipeline. The multiple heating water tanks are arranged side by side. The steam outlet of each heating water tank is connected to a steam conduit, which extends to the outside of the housing. By connecting the steam conduit to the target space, the humidification assembly can achieve humidification of multiple target spaces or multiple points within a target space. Furthermore, since the outlet of the steam conduit is outside the housing, there is no need to set up an airflow path for mixing steam and air inside the housing, allowing for a smaller housing volume and thus facilitating the miniaturization of the humidification assembly.

[0016] This utility model also proposes a humidity control system.

[0017] A humidity control system according to an embodiment of the present invention includes: a humidification component according to an embodiment of the present invention, wherein the housing is provided with an air inlet, an air outlet, and an airflow passage connecting the air inlet and the air outlet, and the heating water tank is used to humidify the air flowing through the airflow passage; and an air supply component, wherein the air supply component is disposed inside or outside the housing, and the air supply component is used to drive air into and out of the airflow passage.

[0018] The humidity control system according to the present invention, by employing the humidification component of any of the above embodiments, effectively reduces the water temperature at the outlet of the drain pan, thereby reducing the risk of aging and high-temperature damage to the detection element and external pipeline.

[0019] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0043] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0044] Reference Figures 1 to 10 The humidification assembly 100 and humidity control system 1000 involved in the embodiments will be described. Figures 1 to 6 and Figure 9 This is a schematic diagram of a humidification assembly 100 according to different embodiments of the present utility model; Figure 7 and Figure 8This is a schematic diagram of the filter element 36 according to different embodiments of the present invention; Figure 10 This is an application diagram of the humidity control system 1000 according to an embodiment of the present utility model.

[0045] For ease of explanation, the three mutually orthogonal directions are designated as X, Y, and Z. One side of the X direction is designated X1, and the other side as X2; one side of the Y direction is designated Y1, and the other side as Y2; one side of the Z direction is designated Z1, and the other side as Z2, with corresponding vertical directions. Figure 1 The X direction indicated by the arrow, X1 direction, is consistent with the top direction in actual use.

[0046] (Humidifier component 100)

[0047] The humidifier 100 is used for humidifying a target space, such as an indoor space, to regulate indoor humidity. For example, the humidifier 100 can be connected to the fresh air system of the target space, humidifying the air supplied by the fresh air system and then delivering the humidified air into the room to achieve indoor humidification; alternatively, the humidifier 100 can be directly connected to the indoor unit to directly supply steam into the room to achieve indoor humidification. Yet another example is that the humidifier 100 can be connected to an indoor air conditioning unit, mixing the steam with the return air from the indoor unit before being delivered into the room, or the steam can be directly delivered into the room using the indoor unit's fan.

[0048] like Figures 1 to 7 As shown, the humidification assembly 100 includes: a housing 10, a water inlet tank 20, a heating water tank 30, and a drain pan 40.

[0049] (Shell 10)

[0050] like Figures 1 to 5 As shown, the housing 10 provides installation space for components such as the inlet water tank 20, the heating water tank 30, and the drain pan 40. The housing 10 is generally rectangular in shape, consisting of a top wall, a bottom wall, and a peripheral wall. The top wall and the bottom wall of the housing 10 are spaced apart and opposite each other in the X direction, with the top wall located above the bottom wall. The peripheral wall of the housing 10 connects the periphery of the bottom wall and the periphery of the top wall, and the peripheral wall includes a plurality of side walls that are connected end to end along the periphery of the top wall.

[0051] (Inlet water tank 20)

[0052] like Figures 1 to 6As shown, the water inlet tank 20 is disposed inside the housing 10. The water inlet tank 20 can be directly connected to the housing 10 or indirectly to achieve installation of the water inlet tank 20 within the housing 10. The connection method between the water inlet tank 20 and the housing 10 can be, but is not limited to, placing it on the bottom wall of the housing 10, or fastening it to the housing 10 via fasteners or mounting brackets. For example, the water inlet tank 20 may include a tank body and a cover plate. The tank body has an opening facing the X1 direction, and the cover plate seals the opening of the tank body and engages and is fixedly connected to the tank body. The water inlet tank 20 is detachably connected to the top wall of the housing 10 via the cover plate.

[0053] The water inlet tank 20 is connected to an external water source through the water inlet pipe 21, and the water inlet pipe 21 is equipped with a water inlet valve 22.

[0054] The inlet valve 22 can be used to control the opening and closing of the inlet pipe 21. When the inlet pipe 21 is open, external water can enter the inlet tank 20 through the inlet pipe 21; when the inlet pipe 21 is closed, the inlet pipe 21 is disconnected to prevent excessive water from entering and causing the inlet tank 20 to overflow. Alternatively, an overflow pipe can be installed inside the inlet tank 20 to further prevent overflow.

[0055] Here, the housing 10 may have openings such as holes or holes to allow the inlet pipe 21 to extend outside the housing 10, so as to connect the inlet pipe 21 to an external water source; or, the housing 10 may have openings such as holes or holes to allow an external water source to extend into the housing 10, so as to connect to the inlet pipe 21. The external water source may be, but is not limited to, municipal water. The inlet valve 22 may be, but is not limited to, a solenoid valve, a shut-off valve, etc., among which the solenoid valve has the advantages of simple piping and low cost. The inlet valve 22 may be located inside or outside the housing 10.

[0056] (Heating water tank 30)

[0057] like Figures 1 to 6 As shown, the heating water tank 30 is located inside the housing 10. The heating water tank 30 can be directly connected to the housing 10 or indirectly connected to achieve the installation of the heating water tank 30 inside the housing 10. The connection method between the heating water tank 30 and the housing 10 can be, but is not limited to, placing it on the bottom wall of the housing 10, or fastening it to the housing 10 with fasteners or mounting brackets.

[0058] The heating water tank 30 is mainly used to heat liquids such as water to generate steam, which can be discharged into the target space to achieve the humidification function. Specifically, the inlet water tank 20 is connected to the heating water tank 30 through the water supply pipe 60 to supply water to the heating water tank 30; the heating water tank 30 is equipped with a heating element 31, which is configured to heat the water in the heating water tank 30; the heating water tank 30 is equipped with a steam outlet 32, which is configured to output the steam generated by heating the water.

[0059] The heating element 31 can heat the water in the heating tank 30, raising the water temperature (e.g., to boiling point) to generate steam. The generated steam can be output to the outside of the heating tank 30 through the steam outlet 32, for example, to the room to achieve indoor humidity regulation.

[0060] Here, as Figures 1 to 6 As shown, the heating water tank 30 may include a tank body 34, which has a receiving cavity for holding water, so that the tank body 34 has the function of storing water, which facilitates the heating element 31 to heat the water to generate steam, and facilitates the maintenance of output steam for a period of time.

[0061] like Figures 1 to 6 As shown, the heating element 31 is disposed within the receiving cavity of the housing 34. The heating element 31 may include a heating section, which is used to heat the water within the receiving cavity, thereby generating steam from the water. Here, the heating section may be, but is not limited to, a heating rod, a heating tube, a heating wire, etc. The receiving cavity may contain one, two, or more heating elements 31, for example... Figure 1 As shown, the cavity contains two heating elements 31, which are arranged side by side in the horizontal direction (Y direction in the example shown, but not limited to this, and may also intersect with the Y direction).

[0062] In addition, the heating element 31 also includes a temperature protector connected to the heating element. The temperature protector can detect the heating temperature of the heating element and control the heating element to cut off power when the heating temperature exceeds the safety threshold, so as to avoid safety hazards such as dry burning.

[0063] like Figures 1 to 6 As shown, the steam outlet 32 ​​can be located on the side wall or top wall of the housing 34 to ensure more efficient steam output within the housing 34. The number of steam outlets 32 can be one, two, three, or more. Providing two or more steam outlets 32 increases the flow area of ​​the output steam and improves the efficiency of steam output.

[0064] (Drainage tray 40)

[0065] like Figures 1 to 6As shown, the drain pan 40 is located inside the housing 10, for example, below the inlet water tank 20 and the heating water tank 30. The drain pan 40 can not only receive the water discharged from the inlet water tank 20 and the heating water tank 30, but also receive the condensate or overflow generated by the inlet water tank 20, the heating water tank 30 and the connecting pipes, so as to prevent water from leaking to the outside of the housing 10.

[0066] Here, the drainage tray 40 can be a separate component located inside the housing 10, or the drainage tray 40 can be an integrally formed structure on the bottom wall of the housing 10, both of which are within the protection scope of this utility model.

[0067] In addition, such as Figures 1 to 6 As shown, the drain pan 40 has a water outlet 41. Water collected in the drain pan 40 (such as water discharged from the inlet water tank 20 and the heating water tank 30 to the drain pan 40, condensate, overflow, etc.) can be discharged through the water outlet 41 to prevent excessive water accumulation in the drain pan 40 from causing overflow. Typically, the outer end of the water outlet 41 is also connected to an external pipeline for discharging the water collected in the drain pan to a suitable location, such as outdoors.

[0068] The drainage tray 40 may include a bottom wall and four side plates, specifically including a first side plate 43, a second side plate 44, a third side plate 46, and a fourth side plate 47. Wherein, as Figures 1 to 6 As shown, the first side plate 43 and the second side plate 44 are spaced apart and opposite each other in the Y direction, and the third side plate 46 and the fourth side plate 47 are spaced apart and opposite each other in the Z direction; alternatively, the first side plate 43 and the second side plate 44 may also be spaced apart and opposite each other in the Z direction, and the third side plate 46 and the fourth side plate 47 may be spaced apart and opposite each other in the Y direction. The water outlet 41 may be located on the bottom wall of the drain pan 40 or on any one of the four side plates.

[0069] like Figures 1 to 6 As shown, a detection element 42 is provided at the water outlet 41. The detection element 42 can be located near the water outlet 41 or inside the water outlet 41. The detection element 42 can be, but is not limited to, a water level sensor, a temperature sensor, etc., used to detect the state of the water in the drain pan 40. The water level sensor (such as a float switch) is used to detect the water level at the water outlet 41, so as to control the working state of the humidification component 100 when the water level is too high, for example, to control the inlet water tank 20 and the heating water tank 30 to stop draining, or to control the on / off state of the water outlet 41. The main body of the float switch is usually made of resin material, which is prone to aging under long-term exposure to high-temperature water. The temperature sensor is used to detect the water flow temperature at the water outlet 41, so as to control the working state of the humidification component 100 when the water temperature is too high, for example, to control the drainage ratio of the inlet water tank 20 and the heating water tank 30.

[0070] Furthermore, the bottom wall of the drain pan 40 may include an inclined surface to form a water guiding angle, with the outlet located at the lowest position to ensure complete drainage of water from the drain pan 40. The water guiding angle of the drain pan 40 can be between 1° and 5°, preferably 2°. If the water guiding angle is too small, the water guiding effect will be insignificant; if the water guiding angle is too large, the water flow rate within the drain pan 40 will be too fast, resulting in poor water mixing and cooling effects. Within the above range, both the water guiding effect and the water mixing and cooling effect of the drain pan 40 are considered.

[0071] In addition, the drain pan 40 can be integrally formed from foamed material and coated with heat-resistant material inside the drain pan 40; the drain pan 40 can also be made of metal.

[0072] (Section 23, Section 33, and Section 50)

[0073] like Figures 1 to 3 As shown, the inlet water tank 20 is provided with a first pipe section 23. The first pipe section 23 is configured to allow water in the inlet water tank 20 to flow out of the inlet water tank 20 through the first pipe section 23, for example, to flow to the hot water tank to supply water to the hot water tank, or to flow to the drain pan 40 to drain water.

[0074] Here, the first pipe section 23 is located on the bottom or side wall of the inlet water tank 20, for example, on the lower part of the side wall or the bottom wall of the inlet water tank 20. Water in the inlet water tank 20 flows out more easily through the first pipe section 23, which is conducive to the complete drainage of the inlet water tank 20 and prevents water residue in the inlet water tank 20 from causing scale buildup or bacterial growth.

[0075] like Figures 1 to 3 As shown, the lower part of the heating water tank 30 is provided with a second pipe section 33. The second pipe section 33 is configured to allow water in the heating water tank 30 to flow out of the heating water tank 30 through the second pipe section 33, for example, to flow to the drain pan 40 to achieve drainage, so as to prevent water from accumulating in the heating water tank 30 for a long time when it is not in use, which would cause bacteria to grow and scale to form.

[0076] like Figures 1 to 3 As shown, the end of the first pipe segment 23, the end of the second pipe segment 33, and the beginning of the third pipe segment 50 are configured to connect to drain water to the drain port 51 of the third pipe segment 50, which is configured to drain water to the drain pan 40 through its drain port 51.

[0077] The direct connection structure of the first pipe segment 23, the second pipe segment 33, and the third pipe segment 50 can be flexibly configured. They can be directly connected by welding or by adapters. For example, the ends of the first pipe segment 23, the second pipe segment 33, and the third pipe segment 50 can be directly connected or connected through a tee pipe. Another example is that the end of the second pipe segment 33 can be connected to any position between the beginning and end of the first pipe segment 23, and the end of the first pipe segment 23 can be connected to the beginning of the third pipe segment 50, thus connecting the second pipe segment 33 to the third pipe segment 50 via a portion of the first pipe segment 23. Yet another example is that the end of the first pipe segment 23 can be connected to any position between the beginning and end of the second pipe segment 33, and the end of the second pipe segment 33 can be connected to the beginning of the third pipe segment 50, thus connecting the first pipe segment 23 to the third pipe segment 50 via a portion of the second pipe segment 33. The above connection methods are structurally simple. Alternatively, the ends of the first pipe segment 23 and the second pipe segment 33 can both be connected to two positions between the beginning and end of the third pipe segment 50, and the ends of the first pipe segment 23 and the second pipe segment 33 can be spaced a certain distance apart on the third pipe segment 50, etc.

[0078] Specifically, such as Figures 1 to 3 As shown, the first pipe section 23 extends downward from the water inlet tank 20 and then extends horizontally; the end of the second pipe section 33 is connected to the horizontal extension of the first pipe section 23, and the connection point is spaced apart from the end of the first pipe section 23; the end of the first pipe section 23 is connected to the starting end of the third pipe section 50.

[0079] When drainage is required, hot water at a higher temperature can be discharged from the heating water tank 30 through the second pipe section 33, while cold water (such as room temperature water) at a lower temperature can be discharged from the inlet water tank 20 through the first pipe section 23. The cold and hot water can flow to the third pipe section 50 and mix there. The temperature of the resulting mixed water is lower than that of the hot water discharged from the heating water tank 30. The mixed water can then be discharged to the drain pan 40 through the drain port 51 of the third pipe section 50. The connections between the first pipe section 23, the second pipe section 33, the third pipe section 50, and the drain valve 52 are usually sealed with adhesive, threaded sealing tape, etc. However, prolonged contact with high-temperature water can affect the sealing performance of these sealing materials, leading to pipe leakage.

[0080] The water in the heating water tank 30 may be too hot. Directly draining it into the drain pan 40 could cause aging of the drain pan 40, the detection element 42, and the external piping of the drain pan 40, making them susceptible to high-temperature damage and reducing their reliability. In related technologies, increasing the heat resistance of the materials can address high-temperature damage and aging, but this increases costs. Some technologies extend the length of the drain pipe to allow the hot water to cool naturally as it flows, but this increases the overall size and complexity of the equipment. Other technologies inject room-temperature water into the heating water tank, mix and cool it before draining, but when there is a large amount of hot water in the heating water tank, the amount of room-temperature water that can be injected is limited, requiring a longer time to allow the water temperature to drop naturally, resulting in a longer drainage time.

[0081] In the above embodiments of this application, the hot water discharged from the heating water tank 30 and the cold water discharged from the inlet water tank 20 are mixed through the third pipe section 50, which can reduce the temperature of the water discharged to the drain pan 40, prevent the drain pan 40, the detection element 42 and the external pipeline from being damaged by high temperature, delay the aging of the materials of the detection element 42 and the external pipeline, improve the reliability of the humidification component 100, and achieve cooling during the drainage process of the heating water tank 30 without waiting for the hot water to cool down naturally, thereby improving the drainage efficiency.

[0082] In addition, the highest point of the drain port 51 of the third pipe section 50 can be lower than the upper edge of the side wall of the drain pan 40 to prevent water discharged into the drain pan 40 from splashing out.

[0083] In addition, such as Figures 1 to 3 As shown, the third pipe section 50 is equipped with a drain valve 52, which can be used to control the on / off state and flow rate of the third pipe section 50. For example, the drain valve 52 can be, but is not limited to, a solenoid valve or a shut-off valve.

[0084] Furthermore, at least the second pipe section 33 and the third pipe section 50 are made of heat-resistant materials capable of withstanding certain temperatures (e.g., above 55°C) to prevent aging or damage from high temperatures. For example, copper or stainless steel pipes can be used, which have good heat resistance and are easy to process. Moreover, in the above embodiment, other pipes such as the first pipe section 23 and external pipes do not need to use heat-resistant materials, which helps reduce the cost of the humidification component 100 and its installation.

[0085] In addition, such as Figures 1 to 3As shown, the outlet 41 of the drain pan 40 is located near the first side plate 43 of the drain pan 40, and the drain port 51 of the third pipe section 50 is located near the second side plate 44 of the drain pan 40. This arrangement ensures that the outlet 41 of the drain pan 40 and the drain port 51 of the third pipe section 50 are as far apart as possible in the arrangement direction of the first side plate 43 and the second side plate 44. After the third pipe section 50 discharges mixed water into the drain pan 40, the mixed water can flow a longer path within the drain pan 40 before being discharged from the outlet 41. This allows the mixed water to be further cooled within the drain pan 40, further reducing the risk of aging and high-temperature damage to the detection element 42 and the external piping.

[0086] In addition, such as Figures 1 to 3 As shown, the drain port 51 of the third pipe section 50 does not face either the outlet 41 of the drain pan 40 or the detection element 42, so that the water discharged from the drain port 51 will not directly spray onto components susceptible to high-temperature water. For example, the drain port 51 can face away from the outlet 41 and the detection element 42 in the arrangement direction of the first side plate 43 and the second side plate 44, such as facing the Y2 direction; or the drain port 51 can face the bottom wall of the drain pan 40; or the drain port 51 can face the third side plate 46 or the fourth side plate 47.

[0087] In addition, such as Figure 3 As shown, the inlet water tank 20 can be connected to the heating water tank 30 via a separate water supply pipe 60 to supply water to the heating water tank 30. In other words, the inlet water pipe and the outlet water pipe of the heating water tank 30 are set up separately so that the inlet and outlet water do not interfere with each other and the control is simpler.

[0088] Or such as Figure 1 and Figure 2 As shown, the first pipe section 23 and the second pipe section 33 constitute the water supply pipeline 60; in other words, the inlet water tank 20 can supply water to the heating water tank 30 through the first pipe section 23 and the second pipe section 33; further in other words, the first pipe section 23 and the second pipe section 33 are also used to transport the water in the inlet water tank 20 to the heating water tank 30 for supplying water to the heating water tank 30; in other words, the inlet and outlet of the heating water tank 30 are the same. In this way, there is no need to set up a separate water supply pipeline 60, which simplifies the piping of the humidification component 100 and the structure of the heating water tank 30, and is conducive to miniaturization.

[0089] In an embodiment where the third pipe section 50 is equipped with a drain valve 52 and the first pipe section 23 and the second pipe section 33 are used for water supply, when the drain valve 52 controls the third pipe section 50 to be disconnected, the water in the inlet water tank 20 can flow through the first pipe section 23 and the second pipe section 33 to the heating water tank 30 to achieve water supply; when the drain valve 52 controls the third pipe section 50 to be open, the inlet water tank 20 drains water to the third pipe section 50 through the first pipe section 23, and the heating water tank 30 drains water to the third pipe section 50 through the second pipe section 33 to achieve drainage.

[0090] In addition, such as Figures 1 to 3 As shown, the third pipe section 50 may be equipped with a filter 53. The filter 53 is located upstream of the drain valve 52. The filter 53 can filter the water discharged from the inlet water tank 20 and the heating water tank 30, making it difficult for scale and other impurities to enter the drain valve 52, thus preventing the drain valve 52 from becoming clogged and unable to drain. The filter 53 can be, but is not limited to, a Y-type filter 53, which is convenient for disassembly and cleaning of scale.

[0091] (First drainage pipe 70)

[0092] like Figure 4 and Figure 5 As shown, a first drain pipe 70 is provided at the lower part of the heating water tank 30, and a first control valve 71 is provided on the first drain pipe 70. The first drain pipe 70 is configured to drain water to the drain pan 40 through its outlet. The drain pan 40 has a first side plate 43 and a second side plate 44 facing each other, with the outlet 41 located near the first side plate 43 and the outlet of the first drain pipe 70 located near the second side plate 44.

[0093] The first control valve 71 is used to control the opening and closing states of the first drain pipe 70. When the first drain pipe 70 is closed, water can be stored in the heating water tank 30 for humidification. When the first drain pipe 70 is open, water in the heating water tank 30 can be discharged into the drain pan 40 through the first drain pipe 70. The outlet of the first drain pipe 70 and the outlet 41 of the drain pan 40 are respectively located close to the first side plate 43 and the second side plate 44, so that the outlet 41 of the drain pan 40 and the outlet of the first drain pipe 70 are as far apart as possible in the arrangement direction of the first side plate 43 and the second side plate 44. After the first drain pipe 70 discharges hot water from the heating water tank 30 into the drain pan 40, the hot water can flow a longer path in the drain pan 40 before being discharged from the outlet 41, so that the hot water is cooled down as much as possible in the drain pan 40, thereby reducing the temperature of the water in contact with the detection element 42 and the external pipeline, and reducing the risk of aging and high-temperature damage to the detection element 42 and the external pipeline.

[0094] (Second drainage pipe 80)

[0095] like Figure 5As shown, the bottom or side wall of the water inlet tank 20 is provided with a second drain pipe 80, which is equipped with a second control valve 81. The second drain pipe 80 is configured to drain water to the drain pan 40 through its outlet. The drain pan 40 has a mixing flow path 45 located between the outlet and the outlet 41 of the first drain pipe 70. The outlet of the second drain pipe 80 is located between the outlet and the outlet 41 of the first drain pipe 70, and the outlet of the second drain pipe 80 is connected to the mixing flow path 45.

[0096] The second control valve 81 is used to control the opening and closing states of the second drain pipe 80. When the second drain pipe 80 is closed, the inlet water tank 20 can supply water to the heating water tank 30 through the water supply pipe 60. When the second drain pipe 80 is open, the inlet water tank 20 can discharge cold water at a lower temperature to the drain pan 40 through the second drain pipe 80. The cold water can mix with the hot water discharged from the first drain pipe 70 in the mixing flow path 45 to obtain mixed water at a lower temperature. The mixed water continues to flow along the mixing flow path 45 to the outlet 41, thereby further reducing the temperature of the water discharged at the outlet 41 and further reducing the risk of aging and high-temperature damage to the detection element 42 and the external pipe.

[0097] The second control valve 81 and the first control valve 71 must operate simultaneously during use; that is, when the first control valve 71 is open to the first drain pipe 70, the second control valve 81 is open to the second drain pipe 80; when the first control valve 71 is closed to the first drain pipe 70, the second control valve 81 is closed to the second drain pipe 80; when the first control valve 71 increases its opening, the second control valve 81 increases its opening; when the first control valve 71 decreases its opening, the second control valve 81 decreases its opening.

[0098] Here, the mixing flow path 45 can be a groove or other flow path formed on the bottom wall of the drain pan 40 to restrict the flow path of the discharged water in the drain pan 40 and improve the mixing effect; or the bottom wall and side wall of the drain pan 40 can cooperate to define a recessed space, and the mixing flow path 45 can refer to any area of ​​the recessed space located between the outlet and the outlet 41 of the first drain pipe 70.

[0099] (Inspection Port 14)

[0100] like Figure 3 and Figure 4 As shown, the housing 10 has an inspection port 14, and at least the projection of the heating element 31 on the wall surface where the inspection port 14 is located overlaps with the inspection port 14. In this way, the heating element 31 can be inspected, disassembled, and reassembled through the inspection port 14, which facilitates the maintenance of the heating element 31.

[0101] Specifically, the housing 34 of the heating water tank 30 is provided with an installation port, and the mounting part of the heating element 31 is installed at the installation port, so that the heating part of the heating element 31 is located inside the housing 34. The projection of the mounting part on the wall where the inspection port 14 is located can overlap with the inspection port 14, making it convenient to remove the heating element 31 from the housing 34 through the inspection port 14.

[0102] Alternatively, the projection of the entire heating water tank 30 onto the wall where the inspection port 14 is located overlaps with the inspection port 14, allowing the entire heating water tank 30 to be maintained and disassembled through the inspection port 14.

[0103] (Filter element 36)

[0104] like Figure 7 and Figure 8 As shown, the bottom or side wall of the heating water tank 30 is provided with a drain outlet 35. In an embodiment that includes a second pipe section 33, the drain outlet 35 is connected to the second pipe section 33. In an embodiment that includes a first drain pipe 70, the drain outlet 35 is connected to the first drain pipe 70. A filter element 36 is provided at the drain outlet 35.

[0105] The water in the heating water tank 30 can be discharged through the drain outlet 35. The drain outlet 35 is located on the bottom wall of the heating water tank 30, which can completely drain the water in the heating water tank 30 and prevent residual water from breeding bacteria.

[0106] The filter element 36 can be, but is not limited to, a filter screen, a filter cover, etc. The filter element 36 can filter the water discharged from the heating water tank 30, making it difficult for scale in the heating water tank 30 to enter the drain outlet 35, which helps to ensure the life of valves and other components installed in the drain path.

[0107] Here, as Figure 7 and Figure 8 As shown, the surface of the filter element 36 facing the interior of the heating water tank 30 includes an inclined surface 361. This inclined surface 361 extends at an angle relative to the horizontal direction, making it easier for large scale particles inside the heating water tank 30 to slide down the inclined surface 361 to the bottom of the tank body 34, preventing them from entering the interior of the filter element 36 and clogging the drain outlet 35. The inclined surface 361 can be flat or curved. For example, the surface of the filter element 36 facing the interior of the heating water tank 30 includes two opposing inclined surfaces 361, both extending at an angle relative to the horizontal direction. The distance between the two inclined surfaces 361 gradually increases towards the drain outlet 35, forming a triangular or trapezoidal cross-section for the filter element 36, further reducing the likelihood of clogging the drain outlet 35.

[0108] like Figure 7As shown, in an embodiment where multiple heating elements 31 are provided in the heating water tank 30, the filter element 36 can be arranged between two adjacent heating elements 31 in the arrangement direction of the multiple heating elements 31 (Y direction in the example shown in the figure), so that the filter element 36 can make full use of the space between the two adjacent heating elements 31. The height of the filter element 36 protruding from the wall where the drain outlet 35 is located (the dimension in the X direction in the example shown in the figure) can be as high as possible to increase the filtration area and improve the filtration efficiency.

[0109] (Overview of Humidifier Component 100)

[0110] like Figure 1 and Figure 2 As shown, a humidification assembly 100 according to a specific embodiment of the present invention includes a housing 10 and an inlet water tank 20, a heating water tank 30, a drain pan 40, a first pipe section 23, a second pipe section 33, and a third pipe section 50 disposed within the housing 10. The top wall of the inlet water tank 20 is connected to an external water source via an inlet pipe 21, which is equipped with an inlet valve 22. The bottom wall of the inlet water tank 20 is provided with the first pipe section 23. The heating water tank 30 is equipped with a heating element 31. The upper part of the side wall of the heating water tank 30 is provided with a steam outlet 32, and the bottom wall of the heating water tank 30 is provided with a drain outlet 35, which is connected to the second pipe section 33. The drain pan 40 is disposed below the inlet water tank 20 and the heating water tank 30. The drain pan 40 is provided with a water outlet 41, and a detection element 42 for detecting the water level is provided at the water outlet 41. The third pipe section 50 is equipped with a drain valve 52. The first pipe section 23 and the second pipe section 33 are both connected to the inlet port of the third pipe section 50. The drain port 51 of the third pipe section 50 is connected to the drain pan 40.

[0111] With drain valve 52 connected to the third pipe section 50, inlet valve 22 can be opened or closed. Cold water in inlet tank 20 flows through first pipe section 23 to third pipe section 50, while hot water in heating tank 30 flows through second pipe section 33 to third pipe section 50. The cold and hot water mix in third pipe section 50 to form mixed water, the temperature of which is lower than the water temperature in heating tank 30. This mixed water is discharged through drain port 51 into the area near the second side plate 44 within drain pan 40, then flows towards the first side plate 43 within drain pan 40, naturally cooling during the flow, and finally discharged through outlet 41 near the first side plate 43. Thus, the water temperature at outlet 41 is low, minimizing the risk of high-temperature impact on the detection element 42 and the external piping of drain pan 40.

[0112] With the drain valve 52 closed and the third pipe section 50 closed, the water in the inlet water tank 20 can flow through the first pipe section 23 and the second pipe section 33 to the heating water tank 30 to supply water to the heating water tank 30. The heating element 31 heats the water in the heating water tank 30 to generate steam. The steam can be discharged through the steam outlet 32 ​​and flow to the object space to achieve humidity regulation of the object space.

[0113] (Multiple heating water tanks, 30)

[0114] like Figure 9 As shown, there are multiple heating water tanks 30. The inlet water tank 20 is connected to each of the multiple heating water tanks 30 through a water supply pipe 60. The multiple heating water tanks 30 are arranged side by side (e.g., Figure 9 (As shown in the example, arranged along the Y direction), each heating water tank 30 has a steam outlet 32 ​​connected to a steam conduit 90, which extends to the outside of the housing 10.

[0115] The steam conduit 90 is used to transport the steam output from the steam outlet 32 ​​to the outside of the housing 10. For example, the steam conduit 90 is connected to the target space (such as indoors) to deliver steam to the target space and realize the humidification function. Multiple steam conduits 90 corresponding to multiple heating water tanks 30 can be connected to different locations in the same target space to improve the humidification uniformity of different locations in the target space; multiple steam conduits 90 can also be connected to different target spaces to meet the humidification needs of each target space.

[0116] Here, since the outlet of the steam duct 90 is outside the housing 10, there is no need to set up an airflow passage 13 for mixing steam and air inside the housing 10, and the volume of the housing 10 can be smaller, which is conducive to miniaturization of the humidification component 100.

[0117] When the capacity of the heating water tank 30 is greater than that of the inlet water tank 20, or when the total hot water volume of multiple heating water tanks 30 is greater than the amount of room temperature water in the inlet water tank 20, in order to ensure the mixed water temperature, the inlet valve 22 can be opened during the drainage process and water can be supplied continuously for a certain period of time so that the high temperature water in the heating water tank 30 can obtain sufficient room temperature water to mix with it.

[0118] Alternatively, the opening of the first control valve 71 of the heating water tank 30 can be adjusted to allow the discharged high-temperature water to be fully mixed with the room-temperature water.

[0119] (Humidity Control System 1000)

[0120] like Figure 6 and Figure 10 As shown, the humidity control system 1000 can be used to control the humidity of an object space. Specifically, the humidity control system 1000 includes a humidification component 100 and an air supply component 200.

[0121] The housing 10 of the humidification component 100 is provided with an air inlet 11, an air outlet 12, and an airflow passage 13 connecting the air inlet 11 and the air outlet 12. The heating water tank 30 is used to humidify the air flowing through the airflow passage 13. The air supply component 200 is located inside or outside the housing 10 and is used to drive air into and out of the airflow passage 13.

[0122] The air supply assembly 200 may include components such as a motor and a fan. Driven by the air supply assembly 200, outside air enters the housing 10 through the air inlet 11, passes through the airflow passage 13, and is humidified by the heated water tank 30 within the airflow passage 13. The humidified air then flows out through the air outlet 12. The mixing of steam and dry air within the airflow passage 13 helps to improve the uniformity of the mixing.

[0123] Furthermore, the humidification component 100 can be located downstream of the air supply of the ventilation equipment. The air supply outlet of the ventilation equipment can be connected to the air inlet 11 of the humidification component 100 via a duct. Air is supplied using the blower in the ventilation equipment, allowing the steam in the humidification component 100 to be delivered to the area requiring humidification. This eliminates the need for an air supply component 200 in the humidification component 100, facilitating miniaturization. The air outlet 12 of the humidification component 100 can be connected to the air supply grille of the target space via a duct, allowing air to be supplied to only one target space or to multiple target spaces via branch ducts.

[0124] Furthermore, the humidity control system 1000 of the above embodiment can also be combined with air conditioners, ventilation equipment, etc., to form various air handling systems. For example, such as Figure 10 As shown, an air handling system can be formed, including a humidity control system 1000, an indoor unit 300, and an outdoor unit 400. The indoor unit 300 and the outdoor unit 400 are connected through a refrigerant pipe 700 to form a temperature control system to achieve temperature control. The humidity control system 1000 is connected to at least one object space through a supply air pipe 500 and a return air pipe 600 to achieve functions such as fresh air intake, exhaust air, internal circulation, ventilation, and humidification in the object space. The humidity control system 1000 and the temperature control system can be connected through a communication path 800 (which can be wired or wireless) to enable humidity control and temperature control to work together to achieve functions such as fresh air exchange, temperature and humidity control in the object space.

[0125] In the description of this specification, references to terms such as "one embodiment," "some embodiments," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

[0126] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
