Abstract

PURPOSE:To enable ensurance of a given humidifying amount without using a heat exchanger and a heater by a method wherein a circulating passage through which a part of an amount of air discharged with the aid of a blower is sucked again to the blower before it flows to a humidifier is formed. CONSTITUTION:A part of air discharged from a blower 7 is returned through a circulating passage 16a to an air duct 17 on the suction side since an air duct 18 on the discharge side is brought into a positive pressure state and the air duct 17 on the suction side is brought into a negative pressure state. Thus, a work amount of the blower 7 is a total sum of an amount of blast passing a humidifier 1 and a circulating air amount. A load exerted on a motor 15 is also increased and a motor input is also increased. Since heat energy of a motor input is all converted into heat energy, with the increase in a circulating air amount, an air temperature is also increased. A humidifying amount amounts to q=A.t<1.6-1.8>, and is increased in proportion to 1.6-1.8-th power of an air temperature(t). Thus, circulation of air enables provision of a given humidifying amount through circulation of air without using a heat exchanger and a heating device, e.g., heater.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a humidifying device for air conditioning.

[Conventional technology]

FIG. 3 is a cutaway front view of a conventional humidifying device disclosed in, for example, Japanese Utility Model Publication No. 61-189117, and FIG. 4 is a cross-sectional view taken along the line IV--IV in FIG. Humidifier, 2 is a water tank, 3 is from this water tank 2 to humidifier 1
4 is a float sinch provided in the water tank 2; 5 is a solenoid valve that is turned on and off by the switch 4; 6 is a heat exchanger installed in parallel with the humidifier L;
7 is a blower, which is rotationally driven by a motor 9; Reference numeral 8 indicates a filter provided at the air intake port, and reference numeral 10 indicates a housing that accommodates each of the above-mentioned constituent members.

Further, detailed diagrams showing the structure of the humidifier 1 are shown in FIGS. 5, 6, and 7. Reference numeral 11 denotes a hollow porous member formed into a rectangular shape by overlapping porous sheets 12 and adhering or heat-sealing the ends, and a water supply port 13 communicating with the hollow part 11b at both ends +1a, iJ water. 14 is provided.

Reference numeral 15 denotes a wavy spacer that is rolled up along the hollow porous member 11 so as to form a ventilation path between the stacked hollow porous members when the hollow porous member 11 is rolled up. 16 is a core member having a rectangular parallelepiped outer shape, and the hollow porous member 11 and the wavy spacer 15 are the core member [6
The humidifier 1 is formed by winding it around the center core member 16.

A conventional humidifying device incorporating an additive device made of a porous sheet is constructed as described above, and water for additive W is first supplied to the water tank 2, which is opened by actuating the electromagnetic valve 5 using the float switch 4. The water is supplied to the hollow portion 11b of the hollow porous member 11 of the humidifier l through the water supply vibrator 3. On the other hand, when the humidifier is in operation, a flow of air is generated by the blower 7, and the air is sent from the filter 8 through the blower 7 to the heat exchanger 6, and the air heated by the heat exchanger 6 through which hot water is passed is humidified. Water flowing between the hollow porous members 11 formed by the wavy spacers 15 of the container 1 and further supplied to the hollow portion 11b of the hollow porous member 11 becomes steam and passes through the porous sheet 12. The air is then humidified and sent out from an air outlet (not shown).

Since the humidifier 1 described above is of an evaporative type, it has a characteristic that the amount of humidification increases if the temperature of the supplied air is higher than normal temperature, that is, the indoor air temperature. Further, even if the heat exchanger 6 uses a heater, the same effect as described above can be obtained.

[Problem to be solved by the invention]

The conventional humidifying device is configured as described above, and the temperature of the supplied air is raised by the heat exchanger 6, but hot water must be supplied to the heat exchanger 6, and if there is no hot water heat source, There were problems such as the need to use a heating device such as a heater instead of a heat exchanger.

This invention was made to solve the above-mentioned problems, and aims to provide a heating W'J position that can secure a predetermined amount of humidification without using a heat exchanger or heater.

[Means to solve the problem]

The humidifying device according to the present invention is a humidifying device that uses a hydrophobic porous sheet that prevents the passage of water and allows only water vapor to pass through, or a so-called natural humidifying device that uses a cloth or a hydrophilic porous resin that is moistened by the penetrating power of water. In a humidifier equipped with a formal humidifier and a blower for supplying humidified air to the humidifier, a circulation path for sucking a part of the air produced by the blower into the blower again before reaching the humidifier. was formed.

[For production]

In this invention, a part of the air supplied to the humidifier is drawn into the blower through the circulation path, so the heat generated by the motor is sufficient to heat the air, thereby increasing the temperature of the air supplied to the humidifier. Is it expensive? Hf3 can be secured.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
The figure shows a side sectional view of a humidifying device according to the present invention.
In the figure, 1 is a humidifier, 7 is a blower, and 15 is a blower 7.
The motor rotates the air and also heats the air. 8 is a filter provided at the air inlet; 16 is a partition plate that partitions the suction side air passage 17 and the outlet side air passage 18 of the blower 7; and 16a is an air circulation path made in a part of this partition plate 16. be.

Further, 19 is a humidified air blowing grill, and 20 is a housing that accommodates these components.

Next, the operation of this invention will be explained. The air blown out from the blower 7 has a positive pressure in the outlet side air passage 18 and a negative pressure in the suction side air passage 17, so a part of the air flows into the circulation path 16.
The air flows back to the suction side air passage I7 from a. Therefore, the work output of the blower 7 is the sum of the amount of air blown through the humidifier 1 and the circulating air, and the load applied to the motor 15 also increases and the motor input also increases. Since all motor input is converted into thermal energy, the larger the amount of circulating air, the higher the air temperature will be.

Here, the relationship between the temperature of the air passing through the humidifier 1 and the humidification V is shown in FIG. In this figure, the horizontal axis shows the air temperature t, and the vertical axis shows the humidification amount q. In other words, the humidifier has q=A・11.6~1
-8, and increases in proportion to the 1.6 to 1.8 power of the air temperature t. Therefore, by circulating the air, the specified heating can be achieved without using a heating device such as a heat exchanger or heater. W N can be obtained.

Note that the humidifier 1 uses a hydrophobic porous sheet,
Alternatively, as long as it is an f-type humidifier, other types of humidifiers may be used.

〔Effect of the invention〕

As explained above, according to the present invention, a part of the air blown out from the blower is blown again through the circulation path.

Since the humidifier is designed to suck air, a desired humidifier can be obtained without adding a heating device. Further, the humidifying device has a simple configuration, can be made compact, and is inexpensive.
