Description

[Detailed Description of the Invention] The present invention relates to a humidifying device for a heater, and in particular, is configured to heat and evaporate humidifying water using the heat of combustion exhaust and release it.

The applicant previously filed Utility Application No. 54-62617 for a humidifying device that humidifies by effectively utilizing the exhaust air from a heater.
It is proposed in the issue. By the way, this humidifying device has an exhaust inlet 41 from the heater as shown in FIG.
A water storage container 4 is placed in the upper part of the exhaust connecting pipe 42 facing the
3 and then remove the container 4 from the bottom of the container 43.
A hollow tube 44 communicating with the container 43 was installed vertically, and the humidifying water in the container 43 was evaporated by exchanging heat with the exhaust gas. Then, the exhaust gas is discharged to the outside from an exhaust extension pipe 45 that communicates with the lower part of the communication pipe 42, and is also discharged from the container 4.
The steam heated and evaporated in step 3 rose up the steam outlet pipe 46 and was discharged into the room on the air blown from the air outlet 47 of the heater.

The supply of humidifying water to the container 43 was carried out by a water supply pipe 48 that was vertically installed from the bottom of the container, bent horizontally, and led out. As it was being heated by the exhaust air, the feed water boiled and precipitated impurities in the water, such as magnesium and calcium. Therefore, impurities adhere to the inside of the water supply pipe, clogging it and obstructing the water supply, resulting in a reduction in humidification capacity.

The present invention is aimed at solving the problems caused by the above-mentioned prior art, and one embodiment thereof will be described below with reference to FIGS. 1 to 3.

Reference numeral 1 denotes a heater installed indoors, which is partitioned by a partition plate 2 and has a ventilation chamber 3 formed in its upper part and a heat exchange chamber 4 formed in its lower part. Reference numeral 5 denotes a blower disposed inside the blower chamber 3, which supplies air to the blower chamber 3 through a filter 6.
The indoor air that has flowed into the chamber is accelerated and discharged into the heat exchange chamber 4.

Reference numeral 7 denotes a closed type combustor disposed within the heat exchange chamber 4, which introduces combustion air from outside through an air supply and exhaust pipe 8, and sends combustion exhaust to the exhaust pipe 9, an extension pipe 10, the air supply and exhaust pipe 8, etc. The hot air is discharged to the outside through the air blower 5, and the air from the blower 5 is heated to supply warm air into the room.

Reference numeral 11 denotes a hollow cylindrical exhaust connecting pipe which has an exhaust inlet 12 formed in a proper position on the side wall to be detachably connected to the exhaust pipe 9, and one end of the extension pipe 10 is rotatably fitted in the lower part of the exhaust connecting pipe 11. and an exhaust outlet 13,
It forms part of the exhaust path of the combustor 7.

Reference numeral 14 designates an exhaust inlet 12 on the lower outer peripheral surface of the exhaust connecting pipe 11 so as to airtightly close the upper opening of the exhaust connecting pipe 11.
This water storage container 14 is closely fixed to the inner circumferential surface of the exhaust communication pipe 11 located above the water storage container 14. The water storage container 14 is formed into a bowl shape with an open top, and has a bottom surface that protrudes into the exhaust communication pipe 11 from the outside. The distal opening of the installed water supply pipe 15 is protruding, and the water supply pipe 15 has a plurality of heat exchange mediums with only the upper part open and the opening slightly protruding into the water storage container 14. Spaces 16, 16, . . . are provided hanging down along the exhaust flow descending within the exhaust communication pipe 11. Then, the water storage container 1 that has flowed down into these hollow spaces 16, 16...
The humidifying water in the humidifier 4 is heated and boiled by the heat of the exhaust gas from the combustor 7 passing through the exhaust communication pipe 11, and is turned into water vapor.

Here, the water supply pipe 15 passes through the upper side wall of the exhaust communication pipe 11 obliquely from below, opens at the bottom side of the container 14, and is formed from a straight pipe. Therefore, this water supply pipe 15 is the exhaust communication pipe 11.
The surface area in contact with the exhaust gas is kept very small. Note that 17 is a water supply extension pipe detachably connected to the water supply pipe 15.

Reference numeral 18 denotes a hollow cylindrical connecting pipe connected to a portion of the water storage container 14 that protrudes from the upper part of the exhaust communication pipe 11, into which water vapor generated in the water storage container 14 is pressurized and led out. A hollow cylindrical steam outlet pipe 19 is installed with its upper opening extending upward, and the side wall of the connecting pipe 18 located above the base of the steam outlet pipe 19 is provided with the air blower 5. A discharge port 20' of the blast pipe 20 is provided to introduce a portion of the air.

Reference numeral 21 denotes a hollow resin blow-off tube having a blow-off port 21' at the tip thereof. The water vapor ejected from the blower mixes with the wind supplied from the blower pipe 20 in the blower tube 21 and is discharged into the room from the blower outlet 21'.

22 is a water supply device attached to the back of the heater 1;
A water tray 24 supported on a support plate 23 fixed to the heater 1, a portable water tank 25 placed on the water tray 24, a water tray 24, and a water storage container 14.
The water storage container 14 supplies humidifying water to keep the water level at a low level at all times. Further, 28 is an air supply hose.

Next, when talking about the action, first of all, the water tank 25
After filling the water tank 25 with water, transfer the water tank 25 to the water tray 24.
humidifying water is supplied to the water storage container 14.
When the heater 1 is driven in this manner, the combustor 7 starts combustion, and the combustion exhaust flows out from the exhaust pipe 9, passes through the exhaust communication pipe 11 and the extension pipe 10, and is then discharged outside via the air supply and exhaust pipe 8. . On the other hand, the air from the blower 5 is heated by the combustor 7 in the heat exchange chamber 4 to become warm air and discharged into the room. At this time, the exhaust air flows from the exhaust inlet 12 to the exhaust outlet 13 along the surfaces of the hollow tubes 16, 16, in the exhaust communication pipe 11.
The heat of the exhaust air is transferred to the hollow tube 16,
The humidifying water flowing into the water storage container 14 is heated. By the way, the calorific value of combustor 7 is
If it is about 4000 kcal/h, the temperature of the exhaust gas falling in the exhaust communication pipe 11 is high temperature of about 200°C to 230°C, and the heat transfer area of the humidifying water is large due to the hollow pipe 16. Therefore, a large number of bubbles are continuously generated in each hollow tube 16, 16, . Then, this water vapor is ejected from the steam outlet pipe 19 into the blower tube 21, mixed with the wind supplied from the blower tube 20 in the blower tube 21, and released into the room from the blower outlet 21' to humidify the room. It is something that can be achieved. On the other hand, the humidifying water in the water supply pipe 15 is also heated by exchanging heat with the exhaust gas, but since the heat exchange area is small, the degree of heating is extremely small compared to other humidifying water, and precipitation of impurities can be reduced. In addition, if impurity precipitation occurs, remove the water supply extension pipe 17 and connect the water supply pipe 1 from the outside.
5. Insert the cleaning stick into the hole and clean it. At this time, since the water supply pipe 15 has a straight pipe shape, deposited impurities are less likely to adhere to it, and it is also easier to clean.

FIG. 5 shows a main part of another embodiment of the present invention, in which a straight water supply pipe 15' is connected to an exhaust communication pipe 11.
It penetrates the upper side of the container 14 approximately horizontally and communicates with the container 14 from the side. Therefore, since this water supply pipe 15' is not directly exposed in the exhaust communication pipe 11, there is no heating due to exhaust gas, and there is almost no precipitation of impurities. Incidentally, this water supply pipe 15' may be inclined so that even the slightest amount of impurity can be prevented from adhering to the water supply pipe 15'.

In this way, the humidifying device for a heater according to the present invention is
A water storage container is closely fixed to the upper part of the communication pipe for the exhaust air of the heating machine, and a hollow pipe is installed hanging from the bottom of the container, and the upper side wall of the communication pipe is penetrated into this container from the outside. Since the straight water supply pipes are connected to each other, contact between the water supply pipes and the exhaust gas is inevitably reduced or eliminated, which suppresses the temperature rise of the supply water and prevents precipitation of impurities in the water. Therefore, it is possible to prevent a decrease in humidifying capacity due to clogging in the water supply pipe.

In addition, since the water supply pipe is straight, the inside of the pipe can be cleaned very easily, and there is less residual impurity, making it easy to handle without bothering the user.
