Abstract

PROBLEM TO BE SOLVED: To prevent a water tank 2 from being dented depending on its shape, as denting force acts inside of the water tank 2, when the inside of the water tank 2 has a negative pressure due to water supply to a water tank portion 3 from the water tank 2.SOLUTION: A supporting member preventing deformation of a water tank 2, is mounted inside of the water tank 2 of a humidifier configured by joining an upper tank 10 and a lower tank 11. As the inside of the water tank 2 has a negative pressure, denting of the water tank 2 can be suppressed by being supported by a supporting member 16, even when denting force acts the inside of the water tank 2. Further, as the supporting member 16 is composed of a component separating from the water tank 2, the lower tank 11 can be deformed corresponding to the deformation of the upper tank 10, so that the force does not concentrate on a joining portion, and breakage of the water tank 2 can be prevented.

Description

  The present invention relates to a humidifying device for preventing indoor drying, and particularly to a humidifying device including a detachable resin water tank.

  Conventionally, a humidifier equipped with a detachable water tank and a water tank part for storing water supplied from the water tank is generally used. In such a humidifier, when water in the water tank is consumed by the humidifying operation, water is supplied from the water tank to the water tank, and constant water is always stored in the water tank.

  Specifically, when the water tank is attached to the water tank portion with the water supply port down, the valve mechanism provided at the water supply port is opened to supply water from the water tank to the water tank portion. . At this time, if the water level of the water tank part is equal to or higher than a predetermined level (more than the water supply port), the water supply port is blocked by the water surface, so water is not supplied to the water tank part, but water is supplied when the water level is below the end of the water supply port. Since the mouth is opened, ambient air is introduced into the water tank as bubbles, and water corresponding to this air is supplied to the water tank section. That is, water is supplied to the water tank section by exchanging water inside the water tank with air.

  And like patent document 1, while forming a water tank from a transparent or semi-transparent synthetic resin so that the amount of water inside a water tank can be confirmed easily from the outside, a part of the exterior of a humidifier is constituted. There is what I did.

JP 2010-121891 A

  However, in the above-described humidifier, water is supplied from the water tank to the aquarium, so that the inside of the water tank becomes negative pressure due to the water column. Depending on the shape of the water tank, it may be recessed by this force. In particular, in the case of a structure in which the water tank forms a part of the exterior as in Patent Document 1, there is a problem that the appearance is impaired by the depression of the water tank.

  Moreover, since the inside of the water tank is maintained in a negative pressure state due to the depression of the water tank, it becomes difficult for air to enter the water tank, and the frequency of exchange of water and air inside the water tank is reduced. Therefore, a large amount of air was introduced into the water tank at once, and when this bubble rose up in the water and played on the surface of the water, a loud sound `` Bokkon '' was generated and it was felt annoying .

  This invention is for solving the said subject, and it aims at providing the humidification apparatus which suppressed the deformation | transformation of the water tank.

  The present invention is a humidifying device having a resin water tank that is detachably mounted, wherein the water tank is formed by joining an upper tank and a lower tank, and the water tank is deformed inside. The humidifying device is characterized in that a supporting member for preventing the above is attached.

  Further, the water tank has a substantially rectangular parallelepiped shape having a wide surface and a narrow surface, and the support member is formed of a plate-like member and is provided between the wide surfaces facing the water tank. A humidifying device according to claim 1.

  The humidifying device according to claim 2, wherein the support member is fitted and fixed to a fixing portion provided in the lower tank.

  4. The humidifying device according to claim 3, wherein a part or all of the lower end of the support member and the bottom surface of the lower tank do not contact each other.

  The humidifying device according to claim 2, wherein the support member is fitted and fixed to a fixing portion provided in the upper tank, and the fixing portion has a substantially L shape at least in part. .

  The humidifier according to any one of claims 1 to 5, wherein the water tank forms a part of an exterior of the humidifier.

  By configuring as described above, even if the inside of the water tank becomes negative pressure, the supporting member attached to the inside supports and suppresses the depression of the water tank, so that the appearance of the humidifier is maintained and bubbles are generated. The sound is prevented from becoming loud.

  Embodiments of the present invention that are considered to be suitable will be briefly described by showing the effects of the present invention.

  The present invention is configured such that a support member for preventing deformation of the water tank is attached to the inside of the water tank of the humidifier formed by joining the upper tank and the lower tank.

  In other words, when water is supplied from the water tank to the humidifier, the inside of the water tank becomes negative pressure, and a force that causes the water tank to dent inward acts. Can be suppressed. In addition, by configuring the support member as a separate part from the water tank, the lower tank can be deformed in response to the deformation of the upper tank, so that the force does not concentrate on the joint and the water tank is damaged. Will be prevented.

  Moreover, the dent of a water tank can be effectively suppressed by providing a support member between the wide surfaces which are most susceptible to negative pressure.

  Since the support member is fitted and fixed to the lower tank, when the upper tank is assembled to the lower tank, the support member corrects the warp of the upper tank and serves as a guide, so that the assembly is performed smoothly. be able to.

  In addition, although the lower tank is provided with a support member, the interior is partitioned, but a water passage is formed between the support member and the bottom surface of the lower tank. Water flows between them, and the water in the water tank can be used up to the end.

  In addition, since the support member is fitted and fixed to the upper tank using a fixing portion having a substantially L-shape at least partially, the support member is supported when an external force is applied when the water tank is full. Since the L-shaped fixed portion is caught by the member, the water tank is also prevented from bulging outward.

  In addition, in the case of a humidifier with a structure in which the water tank forms a part of the exterior, the deformation of the water tank leads to a loss of appearance, but the problem that the appearance is impaired by suppressing the depression of the water tank is avoided. can do.

  An embodiment of the present invention will be described below with reference to the drawings.

  FIG. 1 is an external view of a humidifying device of the present invention. The humidifier is composed of a main body 1, a water tank 2 that supplies water to the humidifier, and a water tank part 3 that stores a certain amount of water supplied from the water tank 2, and the water tank part 3 can be drawn out to the main body 1. The water tank 2 is detachably provided from above with respect to the water tank portion 3. Moreover, the blower outlet 4 which blows out humidified air is provided in the upper surface of the main body 1, and the handle 5 for putting a hand when carrying a humidifier in the upper part of both sides | surfaces is formed.

  FIG. 2 is a view showing a state in which the water tank 2 and the water tank unit 3 are removed from the main body 1. The front surface of the main body 1 has a structure in which an upper portion is covered with a main body front wall 6 and an opening 7 is provided in a lower portion of the main body front wall 6. A water tank housing portion 8 is formed as a space for housing the water tank portion 3. The water tank unit 3 is disposed in the water tank housing unit 8 so as to be drawable. Further, a suction port 9 for taking in indoor air is provided on the back surface of the main body 1, and the suction port 9 communicates with the water tank housing portion 8. Further, a step portion 6 a is bent at the lower end of the main body front wall 6 so as to slightly enter the water tank housing portion 8 from the main body front wall 6.

  The water tank 2 has a substantially rectangular parallelepiped shape having a wide surface and a narrow surface, and is formed of a transparent or translucent synthetic resin so that the amount of water inside can be seen through. And it mounts on the water tank part 3 in the state in which the lower part was inserted in the water tank part 3 so that it may become independent when it mounts | wears with the water tank part 3, and the upper part forms a part of exterior of a humidifier. . In addition, the water tank 2 is manufactured by separately manufacturing an upper tank 10 serving as an exterior of the humidifier and a lower tank 11 inserted into the water tank 3, and then joining the upper tank 10 and the lower tank 11 together. Molded.

  The upper tank 10 comes into contact with the front wall 6 of the main body when the water tank 2 is mounted on the water tank unit 3, and the upper tank 10 has a handle for removing the water tank 2 from the water tank unit 3 on its upper surface. A tank handle 12 is formed. The lower tank 11 has a step portion 13 formed with its upper end extending in the outer peripheral direction, and a tank cap 14 is attached to the bottom surface of the water tank portion 3 from a water supply port 15 formed in the tank cap 14. Water is supplied to the

  FIG. 3 is a sectional view of the water tank 2. Inside the water tank 2, a support member 16 that prevents the water tank 2 from being deformed and recessed is attached between the wide surfaces facing each other. The height of the support member 16 is not required up to the upper end of the water tank 2, and is about the middle of the upper tank 10 here. The lower tank 11 is provided with a fixing portion 17 for fitting and fixing the support member 16 and a tank port 18 to which the tank cap 14 is attached.

  4A is a top view of the lower tank 11, and FIG. 4B is a cross-sectional view taken along the line AA of FIG. 4A, and shows the shape of the fixing portion 17. The fixing portion 17 is composed of two plates 17a and 17b arranged in parallel. The plates 17a and 17b are partially cut away, and at least one of the plates 17a is substantially U-shaped. .

  The support member 16 is a plate-shaped member as shown in FIG. 5, and is fixed to the lower tank 11 by being fitted between the two plates 17 a and 17 b forming the fixing portion 17 from above. The clearance between the support member 16 and the fixed portion 17 is set to be as small as possible so that the support member 16 does not come out of the fixed portion 17 due to the water tank 2 being turned upside down or an impact set in the water tank portion 3. Yes. Further, a claw portion 19 is formed on one surface of the support member 16, and the claw portion 19 is caught by the U-shape of the fixing portion 17 so that the support member 16 is more difficult to come off.

  If the one plate 17a is substantially U-shaped, the fixing portion 17 can hook the claw portion 19 of the support plate 16, so the other does not have to be a single plate. It may be divided and arranged. That is, the support plate 16 only needs to be sandwiched and held between the plates constituting the fixed portion 17.

  Further, a notch 20 is provided at the bottom of the support member 16, and when the support member 16 is fitted into the fixing portion 17, a water passage 21 is formed by the notch 20 and the bottom surface of the lower tank 11. Since the support member 16 is fitted so that there is no gap in the fixed portion 17, when the water surface in the water tank 2 is lowered to the height of the fixed portion 17, water flows between the left and right spaces partitioned by the support member 16. It becomes difficult to circulate, and only the water on the tank port 18 side is consumed and the water on the opposite side remains. However, since water flows between the left and right spaces partitioned by the support member 16 through the water flow port 21, the water in the water tank 2 can be used up to the end.

  The shape of the support member 16 is not limited to that shown in FIG. 5 as long as the water inlet 21 is formed between the support member 16 and the lower tank 11. For example, as shown in FIG. 6, by providing the fixing portion 17 at a predetermined distance d from the bottom surface of the lower tank 11, the water inlet 21 can be formed without providing the support member 16 with a notch.

  Next, molding of the water tank 2 will be described with reference to FIG. First, the support member 16 is fitted and fixed to the fixing portion 17 of the lower tank 11. Next, the end portion of the upper tank 10 is combined with the step portion 13 of the lower tank 11 to make a temporary assembly state, and the joint of the upper tank 10 and the lower tank 11 is joined. In order to prevent the upper tank 10 and the lower tank 11 from shifting when temporarily assembled, it is desirable to provide grooves or positioning pieces in the stepped portion 13. As a bonding method, in addition to bonding using an adhesive such as an organic solvent, welding with an ultrasonic wave, a laser, or a conductive heating element can be used.

  When the water tank 2 has a wide shape (the difference between the width of the narrow surface and that of the wide surface is large), the wide surface of the upper tank 10 is likely to warp inward and deform easily. It was difficult to match the upper tank 10 with. However, since the support member 16 is fitted in the lower tank 11 in advance, the support member 16 corrects the warp of the upper tank 10 and serves as a guide, so that the assembly can be performed smoothly.

  The water tank 3 has a partition plate 22 standing in the center, a water tank housing portion 23 for housing the lower tank 11 of the water tank 2 on the front side across the partition plate 22, and a vaporization filter 24 on the back side. When the water tank unit 3 is attached to the main body 1, the vaporization filter storage unit 25 is stored in the water tank storage unit 8. And when the vaporization filter accommodating part 25 is completely accommodated in the water tank accommodating part 8, the upper end of the partition plate 22 will contact | abut to the level | step-difference part 6a provided in the main body front wall 6, and the water tank accommodating part 8 will be obstruct | occluded. .

  The partition plate 22 is provided with a communication hole (not shown) that allows the water tank housing part 23 and the vaporization filter housing part 25 to communicate with each other, and the water supplied from the water tank 2 to the water tank part 3 is the water tank housing part. The vaporization filter 24 flows into the vaporization filter housing portion 25 through the communication hole 23 and is sucked up by the capillary phenomenon of the vaporization filter 24 so that the vaporization filter 24 is wetted with water.

  FIG. 8 is a longitudinal sectional configuration diagram of the humidifier. Above the vaporization filter 24, a blower 29 including a motor 27 and a sirocco fan 28, and a fan casing 30 that attaches the blower 29 to the main body 1 and forms a passage for humidified air are provided. When the blower 29 is rotated, indoor air is taken in from the suction port 9, and the taken-in air passes through the vaporizing filter 24 that sucks up and wets the water in the water tank unit 3 and becomes humidified air. It passes between the casing 30 and the front wall 6 of the main body and is discharged into the room through the outlet 4.

  In such a humidifier, when water in the water tank unit 3 is consumed by the humidifying operation, water is supplied from the water tank 2 to the water tank unit 3 so that constant water is always stored in the water tank unit 3. It has become. Then, since water is supplied to the water tank unit 3 so that the inside of the water tank 2 has a negative pressure, a force is applied to the upper tank 10 so as to be recessed inwardly with respect to the wide surface. Although the wide surface tends to deform so as to be recessed by this force, the support member 16 provided inside serves as a support, so that the recess of the upper tank 10 can be suppressed.

  Furthermore, since the depression of the water tank 2 is suppressed, the water and air inside the water tank 2 are exchanged normally, so that the bubbles are reduced and the generation noise of the bubbles is reduced.

  When the support member 16 is not provided, the water tank 2 is most deformed in the vicinity of the center in the height direction of the upper tank 10, and the deformation of the water tank 2 gradually decreases when it is above this level. The member 16 need not be provided up to the upper end of the water tank 2. The height of the support member 16 is considered to be most desirably near the center of the upper tank 10, but even if it is about one third from the bottom of the upper tank 10, the effect of sufficiently suppressing the dent can be obtained. it can. If the height of the support member 16 is lowered, the component cost can be reduced.

  By the way, if only the depression of the water tank 2 is suppressed, it is possible to obtain the same effect by forming the support member 16 integrally with the lower tank 11. In addition, if the support member 16 and the lower tank 11 are integrally formed, the lower tank 11 is increased in strength and has a structure that does not deform. However, the water tank 2 not only has the above-described indenting force, but also when the water is full, the weight of the water is applied as a force in the direction of spreading outward with respect to the wide surface of the upper tank 10. The force to deform outside is repeatedly applied. For this reason, if the support member 16 and the lower tank 11 are integrally formed, only the upper tank 10 tries to deform, and the force concentrates on the joint between the upper tank 10 and the lower tank 11. There is a possibility that the joint may be damaged by fatigue.

  Therefore, by configuring the support member 16 as a separate component from the water tank 2, the lower tank 11 can also be deformed in response to the deformation of the upper tank 10, so that no force is concentrated on the joint, Fatigue damage of the water tank 2 can be prevented.

  Further, when the support member 16 and the lower tank 11 are formed integrally, the mold becomes complicated and large. Therefore, the manufacturing cost can be reduced by forming the mold separately.

  Furthermore, as a product variation, a product of a type having substantially the same appearance and different humidification performance is often produced, and in this case, water tanks 2 having different capacities are required. For example, if only the upper tank 10 and the support member 16 are newly manufactured and the capacity of the water tank 2 is changed by changing the height of the upper tank 10, the lower tank 11 can be used for any tank of any capacity. can do. Therefore, it is possible to reduce the mold cost when developing a plurality of variations.

  Next, a second embodiment of the humidifying device of the present invention will be described with reference to FIG. The feature of this embodiment is that the fixing portion 17 for fixing the support member 16 is provided in the upper tank 10 from the first embodiment. Since other points are the same as those of the first embodiment, the description thereof is omitted.

  FIG. 9 is a diagram illustrating a fitting state of the support member 16 according to the second embodiment, and the support member 16 includes flange portions 16b at both ends of a plate-like support plate main body 16a. In addition, a fixing piece 17c including the flange portion 16b is formed on the wide surface of the upper tank 10, and the fixing portion 17 is constituted by the four fixing pieces 17c. FIG. 10 is a view showing a modified example of the fixing portion 17, and at least a part of the fixing piece 17 c has a substantially L shape, and the flange portion 16 b is pressed by one side of the L shape. In addition to the present embodiment shown in (a), (b) a stepped type or (c) a U-shaped type may be used. Further, as shown in (d), the flange portion 16b may be sandwiched by one fixed piece 17c.

  When the upper tank 10 is assembled to the lower tank 11, the flange 16 b of the support member 16 is fitted between the fixed pieces 17 c so that the support member 16 is attached to the inside of the upper tank 10 in advance. And the step part 13 of the lower tank 11 and the edge part of the upper tank 10 are put together temporarily, and a joint is joined.

  When water is supplied from the water tank 2 to the water tank unit 3, the water tank 2 becomes negative pressure, and thus the upper tank 10 is applied with a force to be recessed inside, but the support member 16 is supported and the upper tank 10 The dent can be suppressed. Further, by providing the fixing portion 17 having the above-described shape in the upper tank 10, when an outward force is applied to the wide surface of the upper tank 10 when the water tank 2 is full, the flange portion of the support member 16. Since the fixed piece 17c is caught by 16b, it is also prevented that the upper tank 10 bulges outside.

  Since the upper tank 10 is in contact with the front wall 6 of the main body 1 when mounted on the main body 1, when the upper tank 10 swells, the water tank 2 is inclined in a direction away from the front wall 6 and the appearance is only impaired. In addition, the water tank 2 may be easily dropped from the main body 1. Therefore, such a problem can be solved by preventing the upper tank 10 from expanding.
