Description

[Detailed Description of the Invention] The present invention relates to an improvement of a water heating type humidifier that performs humidification by discharging steam generated by heating.

In this type of humidifier, first and second openings are formed adjacent to each other in the base, and the heating water tank and the second opening are connected to each other through a communication pipe. Each has a water receiving chamber.

Furthermore, a water supply tank is disposed on the base together with a guide case that communicates through the first opening and has an intake port at its lower end, as well as a water supply tank that supplies a fixed amount of water into the water receiving chamber from the second opening.

However, when exposed to water tank ancestors, the air layer in the water tank increases pressure and expands, forcing the water in the water tank to be discharged into the water receiving chamber, causing the water level in the water receiving chamber and the hot water level in the heating water tank to rise. to rise.

In this case, the hot water level in the heating water tank will be slightly higher than the water level in the water receiving chamber due to the specific gravity of the water and hot water, so the hot water in the heating water tank will flow between the guide case and the base or through the intake port of the guide case. and overflows into the water receiving chamber.

As a result, the hot water comes into contact with the water supply tank, further expands the air layer, and forces water to be discharged from the water supply tank, causing the hot water to overflow into the water receiving chamber again.

If this action is repeated, there is a risk of boiling water spilling out of the container and causing burns.

The present invention was developed in view of the above circumstances, and its purpose is to heat water in a way that prevents the hot water in the heating water tank from flowing into the water receiving chamber and overflowing to the outside of the vessel, thereby avoiding the risk of burns. We provide a type humidifier.

An embodiment of the present invention will be described below based on the drawings.

Reference numeral 1 denotes a base, and a first opening 2 and a second opening 3 adjacent to each other in the lateral direction are formed in an upper wall portion 1a of the base.

Furthermore, a wall portion 1b is formed on one side of the base 1 and is located on the side of the first opening 2 and stands up integrally with the wall portion 1b.

Reference numeral 4 denotes a heating water tank, which is attached to the base 1 in such a manner that its open upper surface communicates with the first opening 2 through a gasket 5 in a liquid-tight manner.

A water receiving chamber 6 is formed integrally with the base 1 so as to be depressed from the second opening 3.

The water receiving chamber 6 and the heating water tank 4 are connected at their respective bottoms by a connecting pipe 7.

Reference numeral 8 denotes a first surrounding wall, which is integrally erected on the top wall 1a together with a portion of the wall 1b so as to surround the first opening 2.

Reference numeral 9 designates a second surrounding wall portion, which shares a portion of the first surrounding wall portion 8 (indicated by reference numeral 8b in the drawing for convenience), and a second surrounding wall portion 9 is provided on the top wall portion 1a together with this portion 8b. The opening 3 is integrally erected so as to surround the opening 3.

In this state, the height of the portion of the second surrounding wall 9 excluding the shared portion 8b is set to be lower than that of the first surrounding wall 8.

Reference numeral 10 denotes a guide case which is open at the bottom and has an intake port 11 formed at the bottom end. A stepped portion 8 which is fitted into the inner peripheral portion of the wall portion 8 and has an intake hole 11 formed in a common portion 8b of the first and second surrounding wall portions 8 and 9.
It is now in a state where it faces the vertical plane of a, thereby forming a steam chamber A.

Reference numeral 12 denotes a water supply tank mounted on the upper wall 1a of the base 1 so as to be fitted into the second surrounding wall 9, and a water supply port 12a formed on the lower surface of this tank is provided with a water supply tank. cap 13
is screwed so that it faces the water receiving chamber 6.

In this water supply cap 13, 13a is a water supply hole drilled in the center thereof, 14 is an operating rod that is inserted through the water supply hole 13a, and a water supply valve 15 for opening and closing the water supply hole 13a is formed at the upper end of this. A valve body 16 is attached to the water receiving chamber 6, and its lower end is locked to a locking rod 17 provided upright on the inner bottom surface of the water receiving chamber 6. In this state, the valve body 16 opens the water supply hole 13a. ,
When the water in the water supply tank 12 is supplied to the water receiving chamber 6 through the water supply hole 13a and the water level rises and the lower end opening 13b of the water supply cap 13 is blocked by the ice surface, the water supply tank 12
The water supply from the heating ice tank 4 is now stopped, so that the water level in the heating ice tank 4 is always maintained constant.

Note that 18 is a discharge hole formed on the upper surface of the guide case 10;
19 is a sheathed heater attached to the outer bottom wall of the heating water tank 4.

In this embodiment configured in this way, when the sheathed heater 19 is energized by a switch (not shown), the heating water tank 4
is heated and generates a large amount of steam.

The steam thus generated rises through the steam chamber A at an appropriate temperature while being mixed with the air sucked in by the chimney effect from the intake hole 11 at the lower end of the guide case 10, and is discharged to the outside from the discharge hole 18. humidification is performed.

According to the above configuration, the second surrounding wall portion 9 is connected to the first surrounding wall portion 8.
Since the height of the heated water tank 4 is set lower than the height of the first enclosing wall, even if the water in the water tank 12 is forced to flow into the water receiving chamber 6 by the expanded air, the water level of the hot water in the heating water tank 4 is lower than the first surrounding wall. Before it reaches the height of the second surrounding wall 9, the water spills out from the second surrounding wall 9 to the outside, and therefore the water level of the hot water in the heating water tank 4 has a specific gravity equal to the height of the second surrounding wall 9. Since the water remains at the height of the differential water level, that is, it does not reach the height of the first enclosing wall 8, the hot water will not overflow into the water receiving chamber 6 or the outside, causing burns. It is possible to avoid the danger of

In addition, the height of the second surrounding wall part 9 may be made the same as that of the first surrounding wall part 8, and in this state, a low wall part may be formed in a part of the second surrounding wall part by, for example, a notch.

As explained above, the present invention provides at least a portion of the second surrounding wall that surrounds the second opening that communicates with the water receiving chamber, and a first wall that surrounds the first opening that communicates with the heating water tank. By setting the height lower than the enclosing wall, even when used under conditions of high room temperature due to exposure to sunlight, the hot water in the heating water tank can be prevented from overflowing to the outside, reducing the risk of burns. Therefore, it is possible to provide a water heating type humidifier that can avoid this problem.
