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. However, there was a problem that it was difficult to reliably make large bubbles fine with only the cover provided at the water supply port as described above.

  In addition, when the water tank is erected in the water tank, if the water tank is erected vertically, the water surface will drop evenly from the end of the water inlet during operation, so the surface tension is broken and the amount of air introduced is somewhat constant. However, if the water supply tank is erected obliquely, the end of the water supply port is inclined and the surface tension is broken by a slight change in the water level, so that the amount of air introduced is reduced. Therefore, there has been a problem that the amount of air introduced greatly varies depending on the standing condition of the water supply tank.

  This invention is for solving the said subject, and when supplying water to a water tank part from a water supply tank, it aims at providing the water supply apparatus which always introduces a fixed quantity of air little by little into 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 unit from the water supply port, the water level rises again, and the water supply automatically stops, and the water supply from the water supply port is temporarily accommodated in communication with the water tank unit A water receiving portion that automatically stops water supply due to the rise in the water level is provided in the water tank portion. The liquid receiving portion is provided with drainage regulating means for delaying drainage to the water tank portion, and the water supply port is inserted. The inner peripheral wall shape of the insertion part Those related to water supply device being characterized in that the polygon.

  The water supply device according to claim 1, wherein an end portion of the water supply port is substantially V-shaped.

  Since the present invention is configured as described above, when water is supplied from the water supply tank to the water tank, a constant amount of air is always introduced into the water tank little by little. Does not occur. Therefore, the generation of sound due to large bubbles can be prevented. Moreover, it is possible to prevent the generation of sound due to large bubbles regardless of the standing condition of the water supply tank.

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

  The present invention relates to a water supply device that automatically stops water supply by raising the water level of a water tank unit through a water supply port provided in the water supply tank, and temporarily stores water from the water supply port in communication with the water tank unit. A liquid receiving container that automatically stops, this liquid receiving container is provided with drainage regulating means for delaying drainage to the water tank, and the inner peripheral wall shape of the insertion part into which the water supply port is inserted is substantially polygonal It is. Moreover, the edge part of a water supply opening is made into substantially V shape.

  In other words, water from the water supply tank is stored in the small volume liquid receiving container, and the water level in the liquid receiving container is set before the water level in the water tank is returned to the steady water level (water level at which water supply stops) by the drainage restricting means. Raise the water supply in a short time. Then, since the water is gradually drained from the liquid receiving container to the water tank, the water level in the liquid receiving container is immediately lowered and water supply is resumed. Therefore, the water level in the liquid receiving container is raised again to stop water supply. By repeating the water supply and the stop in this way, air is frequently introduced little by little into the water supply tank, so that no large bubbles are generated in the water supply tank. Therefore, the generation of sound due to large bubbles can be prevented.

  Moreover, since the inner peripheral wall shape of the insertion portion is a substantially polygonal shape, the outer peripheral wall of the water supply port can be held by a substantially polygonal side portion, and a constant gap is formed between the outer peripheral wall of the water supply port at the apex portion of the substantially polygonal shape. Can be secured. Therefore, regardless of the standing condition of the water supply tank, constant air is always introduced little by little into the water supply tank, so that no large bubbles are generated in the water supply tank. Therefore, the generation of sound due to large bubbles can be prevented.

  Furthermore, since the end portion of the water supply port has a substantially V shape, the surface tension can be easily broken on both sides of the substantially V shape with a slight drop in the water level in the liquid receiving storage portion. Since the surface tension can be reliably broken on either side of the substantially V shape even if the water supply port is inserted at an angle to the water supply tank, a constant amount of air is always introduced into the water supply tank little by little. No large bubbles are generated inside. Therefore, the generation of sound due to large bubbles can be prevented.

  Hereinafter, an embodiment of a humidifier equipped with a water supply apparatus of the present invention will be described with reference to the drawings. Furthermore, the inner peripheral wall shape of the insertion part of the liquid receiving container will be described as a substantially triangular shape.

  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 small-volume liquid receiving container that is attached to the water tank unit 6 and temporarily stores the water from the water supply tank 7 and automatically stops the water supply from the water supply tank 7 due to the rise in the water level at this time. Reference numeral 16 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.

  Further, as shown in FIG. 4, the liquid receiving container 15 includes an insertion part 17 for inserting the water supply port 13 and a drainage part 18 communicating with the water tank part 6, and the drainage part 18 has a connection to the water tank part 6. A sponge is provided as drainage regulating means 19 for delaying drainage. Furthermore, as shown in FIG. 5, the inner peripheral wall shape of the insertion portion 17 is a substantially triangular shape including three side portions 17a and three vertex portions 17b. FIG. 6 is an enlarged view of the water supply port 13 of the water supply cap 14 provided in the water supply tank 7, and the end 13 a of the water supply port 13 is substantially V-shaped.

  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 16 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 is supplied to the liquid receiver 15. And when not operating a humidifier, the water level of the water tank part 6 and the liquid receiving accommodating part 15 becomes the same height.

  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, the liquid receiving storage unit Since the water level of the water tank unit 6 is lowered from the water level of 15, the water is gradually drained from the drainage unit 18 of the liquid receiving storage unit 15 to the water tank unit 6.

  When the water in the liquid receiving container 15 is drained into the water tank section 6, the water level in the liquid receiving container 15 is lowered, the end 13a of the water supply port 13 is opened from the water surface, and water supply is resumed (a water level). ) Since the water is gradually drained into the water tank 6 by the drainage restricting means 19, the water level in the liquid receiving container 15 rises immediately due to the water supply from the water supply tank 7 and closes the end 13 a of the water supply port 13. Water supply stops in a short time (b water level).

  However, since the water in the liquid receiving container 15 continues to be gradually drained into the water tank 6, the water level in the liquid receiving container 15 immediately drops (a water level), and the end 13a of the water supply port 13 is opened again from the water surface. Since the water supply to the liquid receiving container 15 is resumed, the water level in the liquid receiving container 15 rises again and the water supply stops (b water level). That is, a constant amount of air is always introduced into the water supply tank 7 little by little by repeating a small amount of water supply and stoppage from the water supply tank 7 in a short time due to a change in the water level in the liquid receiving container 15. No large bubbles are generated in 7.

  Moreover, since the inner peripheral wall shape of the insertion portion 17 of the liquid receiving storage portion 15 into which the water supply port 13 is inserted is substantially triangular, the gap between the inner peripheral wall of the insertion portion 17 and the outer peripheral wall of the water supply port 13 is a substantially triangular side portion. 17a becomes small, so even if the water supply tank 7 is tilted and set, the outer peripheral wall of the water supply port 13 is pressed against the side portion 17a, so the water supply port 13 does not tilt, and a constant gap can be secured at the apex portion 17b. For this reason, since a constant amount of air is always introduced little by little into the water supply tank 7, no large bubbles are generated in the water supply tank 7.

  Furthermore, by making the end portion 13a of the water supply port 13 substantially V-shaped, the surface tension can be easily broken on both sides of the end portion 13a of the water supply port 13 even if the water level of the liquid receiving storage portion 15 is slightly lowered. Even if the water supply port 13 is inserted with an inclination with respect to the liquid receiving container 15, the surface tension can be surely broken on one side of the end portion 13a, so that a constant amount of air is always present in the water supply tank 7. Since it is introduced little by little, no large bubbles are generated in the water supply tank 7.
