The air treatment apparatus 1 may include an electric component box, not shown, which is provided in a housing, for example, and in which a circuit board or the like for controlling the operation of the air treatment apparatus 1 is provided.

(Structure of humidifying Assembly)

The humidifying assembly 10 includes: a humidifying element 11; a water tank 12; a water valve 13; and a water pipe connecting the water tank 12, the water valve 13, and the humidifying element 11 in this order. The humidifying element 11 is located on the downstream side of the flow direction of the air flow of the water tank 12. The humidifying element 11 is supplied with water from the water tank 12 through a water pipe and a water valve provided to the water pipe. In the present embodiment, as shown in fig. 1, the humidifying element 11 and the water tank 12 are arranged in the X direction. The humidifying element 11 is located on the X2 direction side (air outlet side) of the water tank 12.

The humidifying element 11 may be provided with one or more. In this embodiment, a case where one humidifying element is provided will be described as an example.

In the present embodiment, the humidifying element 11 is formed in a substantially rectangular parallelepiped shape. The humidifying element 11 has a substantially rectangular shape with a long side along the Y direction and a short side along the X direction in plan view.

The humidifying element 11 may be a wet film humidifier. For example, the humidifying element 11 has a humidifying core portion into and out of which air flows. The humidifying core portion is formed by stacking a first hollow chip through which air flows, a second hollow chip accommodating water, and a moisture permeable membrane (not shown), and water from the water tank 12 can be injected into the humidifying core portion through the water inlet port 111. Air enters the humidifying core portion from the X1 direction and flows out from the humidifying core portion to the X2 direction. During the air flow through the humidifying core 20, it comes into contact with the water in the humidifying core 20, thereby being humidified.

The water tank 12 stores the moisture supplied to the humidifying element 11. As shown in fig. 1 and 2, the water tank 12 has: a housing portion 12a having an upwardly open rectangular parallelepiped frame shape, including a bottom portion 12a1 and a side wall 12a2 formed to extend upwardly from a peripheral edge of the bottom portion 12a 1; and a cover 12b that closes the opening of the housing 12 a. The water tank 12 is arranged between the air intake and the humidifying element 11. The humidifying module 10 may include a water supply pipe for supplying water to the water tank 12 and a water supply solenoid valve (not shown) provided to the water supply pipe, and the water tank 12 is provided between the humidifying element 11 and the water supply pipe.

The water pipe connecting the water tank 12, the water valve 13 and the humidifying element 11 includes: a first water pipe 21 fluidly connecting the water tank 12 to the water valve 13; and a second water pipe 22 fluidly connecting the water valve 13 to the humidifying element 11. Here, by "fluid communication" is meant a state in which fluid is allowed to flow through, for example, the above-mentioned fluid communication of the water tank 12 to the water valve 13 means that fluid (e.g., water) can flow from the water tank 12 to the corresponding port of the water valve 13 through the first water pipe 21.

The water valve 13 is provided in a water pipe connecting the water tank 12, the water valve 13, and the humidifying element 11. The water valve 13 has at least the following three ports: a first port 131 in fluid communication with the tank 12 via a first water line 21; a second port 132 in fluid communication with the humidification element 11 via a second water tube 22; and a third port 133 in fluid communication with drain pan 40 (fig. 5). In the present embodiment, the water valve 13 is a three-way electromagnetic valve having three ports in total, the first port 131, the second port 132, and the third port 133. The water valve 13 can be switched to communicate from the first port 131 to the second port 132, at which time water in the water tank 12 can flow to the port of the humidifying element 11 and into the humidifying element 11 via the first water pipe 21, the water valve 13 and the second water pipe 22. Further, the water valve 13 can be switched such that the second port 132 communicates to the third port 133, at which time water in the humidifying element 11 can flow from the port of the humidifying element 11 to the water valve 13, and into the drain pan 40 via the third port 133. Furthermore, the water valve 13 need not be a solenoid valve, but other forms of valve may be selected.

As shown in fig. 2, 3 and 4, a water outlet port 121 is provided in the bottom 12a1 of the water tank 12. The first water pipe 21 extends downward from the water outlet port 121. The first water pipe 21 includes a first pipe section 21a and a second pipe section 21b connected to each other. The first pipe section 21a is fixedly connected with the outlet port 121 of the water tank 12. The second tube section 21b is fixedly connected to the first port 131 of the water valve 13. The first tube section 21a is a flexible tube having a hardness less than that of the second tube section 21b. By setting the first pipe section 21a connected with the water tank 12 to be a flexible pipe with small hardness, the impact force of water is absorbed, the impact of water on the water valve 13 is reduced, and noise is reduced. The material of the first pipe section 21a is not particularly limited, but is preferably one of a rubber pipe, a PE pipe, and a teflon Pipe (PTFE), more preferably a rubber pipe, and even more preferably a silicone rubber pipe. In the case where the first pipe section 21a is one of a rubber pipe, a PE pipe, and a teflon Pipe (PTFE), not only can the space below the water tank be effectively utilized to realize pipe connection, but also the impact at the water can be absorbed, and an excellent noise suppressing effect can be exerted. The material of the second pipe section 21b is not particularly limited, but is preferably a PVC pipe or an ABS pipe. In the case where the second pipe section 21b is a PVC pipe or an ABS pipe, by selecting the second pipe section 21b bent at a desired angle, it is easy to bend in a desired direction and connect to the water valve 13, and connection stability with the water valve 13 can be ensured.

The water tank 12 has a cylindrical portion 122 protruding downward from the water outlet port 121. The tube 122 is sleeved with the base end of the first tube section 21 a. The first tube section 21a and the second tube section 21b are mutually sleeved. This contributes to improvement in the sealing property of the connection between the tube 122 and the first tube segment 21a and between the first tube segment 21a and the second tube segment 21b. In the present embodiment, the cylindrical portion 122 has a straight cylindrical shape. The tube portion of the base end portion of the first tube segment 21a surrounds the outer peripheral surface of the tube portion 122. The second pipe section 21b has a straight tubular upper tube portion 21b1 protruding upward at the base end. The pipe portion of the front end portion of the first pipe section 21a surrounds the outer peripheral surface of the upper tube portion 21b1. A seal structure (not shown) is preferably provided at least one of the joint between the tube 122 and the first tube segment 21a and the joint between the first tube segment 21a and the second tube segment 21b. The sealing structure is used for tightly fixing the sleeved part, so that the tightness of connection can be further improved. The sealing structure may be a known structure. The sealing structure is preferably a strapping tape or a clip from the viewpoint of easy installation and removal. In addition, the front end portion of the second pipe section 21b and the second port 132 of the water valve 13 may be connected by a threaded connection structure and fastened by a snap fastener.

Further, the first pipe segment 21a preferably has a bent pipe portion (also referred to as a "bent section") 21a1 at least a part of which extends in a bent manner. The bent pipe portion 21a1 is bent so as to be displaced in a direction intersecting the vertical direction as it goes downward (or upward). For example, the bent pipe portion 21a1 is displaced in the flow direction of the airflow as it goes downward. By providing the first pipe section 21a with the bent pipe portion 21a1, the impact force of the discharged water can be further reduced, and noise can be reduced. In the present embodiment, as shown in fig. 3, a bent pipe portion 21a1 is formed in a substantially middle portion of the first pipe section 21 a. Further, since the first pipe section 21a is a flexible pipe having a small hardness, the bent pipe portion can be easily formed.

In the present embodiment, the water outlet port 121 and the water valve 13 are provided so as to be offset from each other in a plan view. That is, in the flow direction of the air flow, the water outlet port and the water valve are arranged in a staggered manner. Therefore, the assembly of the humidifying assembly 10 is convenient, and the first pipe section 21a can form an elbow, which is beneficial to prolonging a waterway, reducing the impact on the water valve 13 and reducing noise.

As shown in fig. 3, flange portions 21a2 and 21a3 that extend radially outward from the outer peripheral surface are provided at the base end portion and the tip end portion of the first pipe section 21a, respectively. When the humidifying module 10 is assembled, the flange portions 21a2, 21a3 can function as handles, facilitating the sleeve-connection of the first pipe section 21a with the outlet port 121 of the water tank 12 and the second pipe section 21b. For example, the flange portions 21a2, 21a3 are integrally formed with the first pipe section 21 a. The shape of the flange portions 21a2, 21a3 is not particularly limited, and for example, the flange portions 21a2, 21a3 have a rectangular shape in a plan view. The flange portions 21a2 and 21a3 may be formed circumferentially over the entire circumference or may be formed as a part of the circumference. Further, a flange portion may be provided only at one of the base end portion and the tip end portion of the first pipe section 21a, and may be extended radially outward from the outer peripheral surface.

In the present embodiment, the second pipe section 21b is an elbow pipe. Thereby, it is convenient to connect the first water pipe 21 with the water valve 13.

Further, it is preferable that the pipe diameter of the first pipe section 21a is different from the pipe diameter of the second pipe section 21b. In the present embodiment, the pipe diameter of the first pipe section 21a is larger than the pipe diameter of the second pipe section 21b. By having the first tube segment 21a and the second tube segment 21b have different diameters, the flow rate of the water flow can be changed, and noise can be further reduced.

In addition, the humidifying assembly 10 further includes an overflow pipe 30 for discharging water exceeding a prescribed water level. In the present embodiment, the bottom 12a1 of the water tank 12 is provided with an overflow port 123. The base end of the overflow pipe 30 is connected to the overflow port 123. The overflow pipe 30 extends downward from the overflow port 123 toward the drain pan 40. In the present embodiment, the overflow pipe 30 includes: a straight pipe 31 having a straight tubular shape, a base end portion of the straight pipe 31 being connected to the overflow port 123, the straight pipe 31 extending downward from the overflow port 123; and an elbow pipe 32 for overflow pipe, which is fixedly connected with the front end of the straight pipe 31 and is bent to have the water outlet inclined toward the drain pan 40. That is, the front end portion of the overflow pipe 30 is provided with an elbow pipe 32 for the overflow pipe. Although not shown in detail, for example, a water overflow tube portion extending upward from the inner surface (upper surface) of the bottom portion 12a1 to a predetermined height is provided at a position corresponding to the water overflow port 123 in the bottom portion 12a1 of the water tank 12. For example, when the water in the water tank 12 exceeds a predetermined water level, the water (excess water) in the water tank 12 exceeding the predetermined water level is discharged to the drain pan 40 through the overflow pipe 30. By providing the elbow pipe 32 for the overflow pipe at the front end portion of the overflow pipe 30, the water falling noise of the water discharged from the overflow pipe 30 to the drain pan 40 can be reduced. The material of the overflow pipe 30 is not particularly limited, and for example, a known material may be used. For example, the rigidity of the overflow pipe 30 (the straight pipe 31 and the elbow pipe 32 for overflow pipe) may be set to be larger than that of the first pipe section 21 a.

In addition, the water tank 12 may be provided with a water level switch (not shown). For example, when a sufficient amount of water is stored in the humidifying element 11 and the water level in the water tank 12 rises to reach the upper limit height of the water level switch, the water supply solenoid valve is turned off, and water supply is stopped. Further, if the humidifying element 11 performs a humidifying function, and thus the water level in the water tank 12 is lowered to reach the lower limit height of the water level switch, the water supply solenoid valve is turned on, and water supply is restarted. The water tank 12 is fixed in the housing of the air treatment device 1 by a connector, not shown, for example. The humidifying element 11 is supported by a casing and a drain pan side wall portion 42 described below, for example, via a support member (not shown). In addition, the tank 12 may be connected to a municipal waterway, or alternatively, water may be manually added.

(Structure of drain pan)

The air treatment device 1 further comprises a drain pan 40, the drain pan 40 being arranged in the housing. The drain pan 40 is provided in a lower portion of an inner space of a not-shown casing of the air treatment apparatus 1. Water flowing from the humidification assembly and the water tank is discharged through the drain pan 40.

As shown in fig. 5, the drain pan 40 includes: a drain pan bottom 41; a drain pan side wall portion 42 erected upward from the drain pan bottom portion 41; and a drain port 43. The drain pan bottom 41 has a thickness in the up-down direction. The drain pan bottom 41 has a substantially rectangular shape in plan view. The upper surface of the drain pan bottom 41 receives water. The drain pan side wall portion 42 has: a first side wall 421 and a second side wall 422, the first side wall 421 and the second side wall 422 being opposite in the flow direction of the air flow; and third and fourth side walls 423 and 424, respectively, connecting the first and second side walls 421 and 422, and opposing in a direction orthogonal to the flow direction of the air flow. For example, the third side wall 423 and the fourth side wall 424 are provided with mounting portions 423a and 424a, respectively, and support members (not shown) that extend in a direction orthogonal to the flow direction of the airflow and support the humidifying element 11 from below are provided on the mounting portions 423a and 424 a.

The drain opening 43 is provided in the third side wall 423. The water in the drain pan 40 is discharged to the outside of the air treatment apparatus 1 via the drain port 43. In the present embodiment, the drain pan bottom 41 is provided with a water storage region R. The water storage region R is, for example, a portion of the upper surface of the drain pan bottom 41 that is most recessed downward. The drain opening 43 is provided in the third side wall 323 at a position corresponding to the water storage region R. The water is guided to the water storage region R and discharged to the outside of the air treatment device through the water discharge opening 43. For example, the upper surface of the drain pan bottom 41 is inclined so as to be located downward toward the outlet 43. Thus, the water accumulation on the drain pan can be suppressed by a simple drain structure.

As shown in fig. 5, the drain port 43 is opposed to the water valve 13 with a certain interval. The third port 133 of the water valve 13 is directed toward the drain port 43, and is inclined so as to be closer to the drain port 43 as being directed downward. This can promote drainage from the third port 133, and further suppress drainage noise. The drain port 43 has an opening 43a, and the opening 43a is opened toward the inside of the drain pan 40 and is opposed to the third port 133 with a certain interval. The opening 43a is inclined in a posture matching the inclined third port 133. The opening 43a is inclined to face the opening portion of the third port 133. This can promote drainage from the third port 133, and further suppress drainage noise.

The utility model has been described above by way of example with reference to the accompanying drawings, it being apparent that the utility model is not limited to the embodiments described above.

For example, in the above embodiment, the overflow pipe is provided in the water tank, and the overflow port 123 at the base end of the overflow pipe is provided at the bottom 12a1 of the water tank 12. However, the present utility model is not limited thereto, and an overflow port may be provided at a side wall of the water tank 12, and water may be prevented from flowing out of an upper portion of the water tank by flowing from the overflow pipe to the drain pan when the water level reaches a predetermined level.

Further, in the above embodiment, the pipe diameter of the first pipe section 21a is larger than the pipe diameter of the second pipe section 21b. However, the pipe diameter of the first pipe section 21a is not limited to this, and may be smaller than or equal to the pipe diameter of the second pipe section 21b.

In the above embodiment, as the humidifying element, an example of a wet film humidifier is given. However, the present utility model is not limited thereto, and other means such as shower humidification, steam humidification, wheel humidification, ultrasonic humidification and the like may be employed as the humidification means, and the humidification means may be connected to the water tank and the water valve via water pipes. For example, a wet curtain may be used as the humidifying element, and the wet curtain may be sprayed by a spraying element, which is connected to the water tank.

The air treatment apparatus 1 may have a blower fan not shown, or may have no blower fan.

Furthermore, the air treatment device 1 may further comprise a temperature regulating assembly (e.g. a heat exchanger or an electric heater) arranged, for example, in the housing on the upstream side of the flow direction of the air flow of the humidifying assembly 10 for temperature regulating the air flow from the air inlet to the air outlet. In the case of the condensed water generated by the temperature adjusting assembly, the condensed water is discharged to the outside of the humidifying device through the drain port 23 of the drain pan 20.

While various embodiments of the present utility model have been described above, each structure and combination thereof in the embodiments are examples, and the addition, omission, substitution and other changes of the structure can be made within the scope not departing from the gist of the present utility model.
