Description

  The present invention relates to a water supply device that automatically supplies water from a cartridge tank (water supply tank) provided in a humidifier to a humidification unit according to consumption.

  A conventional humidifier using a cartridge-type water supply tank inserts a water supply port into a pin portion provided in the water tank portion with the water supply port of the water supply tank filled with water facing down, and this pin portion causes the water supply port to enter the water supply port. The provided valve mechanism is pushed up against the spring and opened to supply water from the water supply tank to the water tank section.

  When the water level rises and reaches the end of the water supply port, the water supply port is blocked by water and the water supply automatically stops.If water is consumed in the humidifying unit during operation, the water level of the water tank unit is When the water level is gradually lowered and lowered to a water level that cannot be maintained even by surface tension, the blocked water supply port is suddenly opened and air is introduced into the water supply tank as large bubbles. At this time, since a large amount of air suddenly becomes a large bubble and is introduced into the tank at a time, a loud sound “bokkon” is generated when the bubble rises in the water and can be repelled on the surface of the water.

Therefore, in order to alleviate the sound of “Bokkon” caused by this large and unpleasant bubble in the past, a proposal was made to reduce the size of the large bubble when it was introduced into the water supply tank by installing a cover at the water supply port. Has been made. (Patent Document 1)
JP-A-10-325574

  However, during operation, if the water surface drops to a water level that cannot be maintained even by surface tension at the end of the water supply port, the end of the water supply port that has been blocked suddenly opens and air is generated as large bubbles. As always, it is difficult to reliably reduce the size of large bubbles with just the cover provided at the water supply port as described above. In addition, since the shape of the parts becomes complicated, it is necessary to add parts and increase the cost of the product. There was a problem of becoming.

  This invention is for solving the said subject, and it aims at providing the water supply apparatus which does not introduce a big bubble to a water supply tank, when supplying water to a water tank part from a water supply tank.

  The present invention provides a water supply tank provided with a water supply port, a water tank part that detachably stands the water supply tank, and a valve mechanism that opens by standing the water tank in the water tank part. When the water level of the water tank portion decreases with the consumption of water, air is introduced into the water supply tank as bubbles from the water supply port via the valve mechanism. In a water supply apparatus configured such that a water amount corresponding to the amount is supplied to the water tank from the water supply port, the water level rises again, and the water supply is automatically stopped, and an opening for allowing air to pass inside the water supply port; A flow straightening plate composed of a closed portion for blocking air and an outer wall of the water supply port are provided with an air introduction portion that opens from the bottom to the top, and the closed portion of the flow straightening plate is disposed at a position corresponding to the air introduction portion, Opening adjacent to the closing part Those related to water supply device, characterized in that the opening area is made smaller than the other openings of.

  2. The water supply device according to claim 1, wherein the current plate is integrally formed with the water supply port.

  Since the present invention is configured as described above, when water is supplied from the water supply tank to the water tank unit, air bubbles are always introduced into the water supply tank. Does not occur. Therefore, the generation of sound due to large bubbles can be prevented. Moreover, since the number of parts can be reduced, the cost of the product can be prevented from increasing.

  The preferred embodiment of the present invention will be briefly described by showing the operation of the present invention.

  In a water supply apparatus that supplies water by increasing the water level of the water tank through a water supply port provided in the water supply tank, in order to make fine bubbles introduced from the water supply port, the opening area of the opening of the rectifying plate may be reduced. If the opening area is reduced, bubbles are accumulated on the rectifying plate due to the surface tension of the bubbles, and water cannot be supplied from the water supply tank to the water tank. Therefore, an opening area where bubbles do not accumulate due to surface tension is required at the opening of the current plate.

  Therefore, in the present invention, an air introduction part that fixes a position where air bubbles are introduced into the water supply port is provided, and the position of the rectifying plate corresponding to the air introduction part is a closed part, and an opening part adjacent to the closed part is provided. The opening area is made smaller than the other openings. In addition, although the opening area of the opening part adjacent to a closing part is made small, since the opening area of the other opening part is enlarged, the bubble introduce | transduced does not accumulate on a baffle plate by surface tension.

  That is, the air bubbles introduced from the air introduction part of the water supply port collide with the closing part of the rectifying plate disposed at a position corresponding to the air introduction part, and the air bubbles that have not been refined are closed. A small bubble is formed by an opening having a small opening area adjacent to. Therefore, since large bubbles are not introduced into the water supply tank, the generation of sound due to the large bubbles can be prevented. Moreover, since the current plate is integrally formed with the water supply port, the cost of the product can be prevented from increasing.

  Hereinafter, an embodiment of a humidifier equipped with a water supply apparatus of the present invention will be described with reference to the drawings.

  From FIG. 1, reference numeral 1 denotes a main body case of the humidifying device, and 2 denotes an operation unit that is located above the main body case 1 and controls the operation of the humidifying device. An outlet 3 is provided for discharging the humidified air into the room. Reference numeral 4 denotes a suction port for taking indoor air into the main body case 1, and reference numeral 5 denotes a vent hole communicating with a humidity sensor (not shown) for detecting indoor humidity.

  FIG. 2 is a vertical cross-sectional configuration diagram of the humidifier, 6 is a water tank unit that stores a certain amount of water supplied from a water supply tank 7, and 8 is disposed in the water tank unit 6 to absorb and wet the water in the water tank unit 6. It is a vaporization filter. Reference numeral 9 denotes a blower fan, and reference numeral 10 denotes a blower motor for driving the blower fan 9. Further, reference numeral 11 denotes a warm air heater which is disposed between the suction port 4 and the vaporization filter 8 and heats the air taken in from the suction port 4 by the blower fan 9.

  That is, the indoor air passes through the ventilation path composed of the suction port 4, the warm air heater 11, the vaporization filter 8, the blower fan 9, and the blower outlet 3, so that it is discharged into the room again as humid air. Become. In addition, the white arrow in a figure has shown the flow of the air taken in in the main body case 1, and the shaded arrow has shown the flow of the humidified air containing a water | moisture content.

  FIG. 3 is an exploded perspective view for explaining the situation where the water tank 7 is erected in the water tank section 6. The water tank 7 is provided with a water supply cap 14 having a water supply port 13 assembled with a valve mechanism 12 composed of a normally closed valve. ing. Reference numeral 15 denotes a bottle portion provided in the water tank portion 6, and when the water supply tank 7 is erected on the water tank portion 6, the spring of the valve mechanism 12 of the water supply cap 14 is pushed up to open the water supply port 13.

  FIG. 4 is an enlarged view of a main part in which a water supply cap 14 is attached to the water supply tank 7, and a rectifying plate 16 that holds the valve mechanism 12 is integrally formed inside the water supply port 13, and the outer wall of the water supply port 13 is formed. Is provided with an inverted V-shaped air introduction portion 17 that opens from the bottom to the top. Further, FIG. 5 is a view of the rectifying plate 16 of the water supply port 13 as viewed from below, but the opening portions 16A and 16C of the rectifying plate 16 and the closed portion 16B in the shaded portion correspond to the air introduction portion 17 (arrow). The closing portion 16B is disposed at a position where the opening portion 16B is located, and the opening area of the opening portion 16A adjacent to the closing portion 16B is smaller than that of the other opening portions 16C. (The black arrow indicates the air introduction part 17)

  In addition, although the shape of the air introduction part of this embodiment is an inverted V-shape, it is not limited to this embodiment, and it is only necessary to open from the lower part of the water supply port 13 to the upper part. Although the introduction part 17 is two places on both sides passing through the center of the water supply port 13, it may be one place on one side, and even in the case of one place, the position corresponding to the air introduction part 17 is the closing part 16B.

  Next, the operation in the above configuration will be described with reference to FIG. When the water supply tank 7 is erected on the water tank section 6 in the main body case 1, the bottle section 15 provided in the water tank section 6 pushes up the spring of the valve mechanism 12 of the water supply cap 14 to open the normally closed valve. Water supply to the water tank unit 6 is started. And when not operating a humidifier, when the water surface of the water tank part 6 reaches the position of the air introduction part 17 of the water supply port 13, water supply will stop. (B water level)

  On the other hand, when the operation of the humidifier is started, the blower fan 9 is rotated by driving the blower motor 10, and when the water in the water tank unit 6 is vaporized and consumed by the vaporization filter 8 by the blown air by this rotation, Since the water level falls, the air introduction part 17 of the water supply port 13 is released from the water surface, and water supply is resumed (a water level). Therefore, every time the air introduction part 17 is opened from the water surface, the water in the water supply tank 7 is supplied to the water tank part 6 and at the same time, the air is bubbled and introduced into the current plate 16 provided inside the water supply port 13. Is done.

  Here, in order to refine the bubbles introduced from the water supply port 13, the opening areas of the openings 16A and 16C of the rectifying plate 16 may be reduced. However, if the opening area is reduced, the rectifying plate 16 is caused by the surface tension of the bubbles. Bubbles accumulate in the water tank 7 and water cannot be supplied from the water supply tank 7 to the water tank section 6. Therefore, the openings 16A and 16C of the current plate 16 need an opening area in which bubbles do not accumulate due to surface tension.

  Therefore, in the present invention, an air introduction part 17 for fixing the position where the bubbles are introduced into the water supply port 13 is provided, and the position of the rectifying plate 16 corresponding to the air introduction part 17 is set as the closed part 16B. The opening area of the opening 16A adjacent to 16B is smaller than that of the other opening 16C. Note that the opening area of the opening 16A adjacent to the closing part 16B is reduced, but since the opening area of the other opening 16C is increased, bubbles that are introduced will not accumulate in the rectifying plate 16 due to surface tension. Absent.

  That is, when the introduced air bubbles are large, the air bubbles collide with the closed portion 16B located at a position corresponding to the air introducing portion 17 of the rectifying plate 16 and are refined. Further, when the microplate is not miniaturized even when it collides with the closed portion 16B of the rectifying plate 16, the opening area of the opening 16A adjacent to the closed portion 16B is reduced, so that large bubbles pass through the opening 16A. When it does, it becomes the bubble of the same size as opening 16A.

  Therefore, since large bubbles are not introduced into the water supply tank 7, it is possible to prevent the generation of sound due to the large bubbles. Moreover, since the baffle plate 16 is integrally formed with the water supply port 13, it is not necessary to attach a separate part to the water supply port 13, thereby preventing an increase in product cost.
