Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a humidifier for humidifying a room by steam generated by heating water.

[0002]

2. Description of the Related Art FIG. 3 is a vertical sectional view showing an example of a conventional humidifier. Reference numeral 1 is a main body case made of synthetic resin, and a partition wall 1a is integrally formed. Reference numeral 2 is an evaporator, 3 is an outer peripheral surface of the evaporator 2, a heating body for heating the evaporator 2, 4 is a tank water receiver, and 5 is a rubber hose connecting the tank water receiver 4 and the evaporator 2. is there. 6 is a water supply tank for supplying water to the tank water receiving portion 4, 7 is a steam guide tube for guiding the steam evaporated from the evaporator 2, 8 is cooling the inside of the main body case 1, and an upper portion 9 of the steam guide tube 7 An air blower that blows cooling air for cooling steam, 10 is an air intake port, 11 is a blowing air outlet, 12 is a hood that covers the upper surface of the steam guide cylinder 7, and 13 is a hood.
Is a steam outlet provided in the hood 12, 14 is a fan casing of the blower 8 formed by a part of the partition wall 1a, and 15 is a bottom plate. Here, the inside of the main body case 1 is vertically divided into two parts by a partition wall 1a, and the upper and lower communication is made with an opening 1b and a blower outlet 1c.

Next, the operation of the humidifier constructed as described above will be described. The water in the water supply tank 6 is stored in the tank water receiving portion 4
The water is supplied to the evaporator 2 through the rubber hose 5 and heated by the heating body 3. The heated water becomes steam and is sent to the steam guide cylinder 7. This steam is blown by the blower 8 from the air intake 10 and the blower outlet 11 to the opening 1
b, it is mixed with the cold air supplied to the upper part of the steam guide cylinder 7 through the air discharge port 1c, and is discharged to the outside from the steam discharge port 13 provided in the hood 12. Here, the blower 8 and the evaporator 2 are arranged side by side at substantially the same height in consideration of the stability of the machine body and the like.

[0004]

In the humidifier constructed as described above, the evaporator 2 is heated to a high temperature by the heating body 3 in order to evaporate water, and as a result, the temperature around the evaporator 2 also rises. The temperature also heats the inside of the main body case 1 and adversely affects the main body case 1 and control parts and the like arranged inside the main body case 1 (especially around the evaporator 2). Therefore, the cooling air taken in to lower the steam temperature by the blower 8 is positively blown around the heating body 3 to lower the surface temperature and prevent the temperature inside the main body case 1 from rising. However, since a large wall called the evaporator 2 is formed in the wind flow, a large pressure loss is generated, and the wind flow is not smooth, causing hot air to be trapped inside the main body case 1. . Further, since the cooling air is blown directly onto the evaporator 2, the heat of the heating element 3 is dissipated by the cooling air, and there is a problem that it cannot be effectively utilized for heating the evaporator 2.

The present invention has been made in order to solve the above-mentioned problems, and an object thereof is to effectively use the heat generated from a heating body to heat the evaporator and to prevent the temperature rise inside the main body case. To do.

[0006]

The humidifier according to the present invention comprises:
The fan casing of the blower that supplies the cooling air is formed by a partition wall that divides the main body case into two parts in the vertical direction, and the blower and the evaporator are arranged side by side, and the blower outlet of the fan casing that blows out from the blower toward the evaporator Is located lower than the evaporator. Also, a partition plate that covers the periphery of the lower surface of the evaporator is arranged in the main body case.

[0007]

In the humidifier according to the present invention, the blower blower outlet from the blower provided in the fan casing is provided at a position lower than the evaporator, so that the cooling wind does not directly blow on the evaporator and the flow of the cooling air flows. As a result, the hot air around the evaporator is sucked and cooled, which allows smooth heat transfer. Further, the partition plate covering the peripheral portion of the lower surface of the evaporator can reduce heat dissipation downward.

【Example】

Example 1. FIG. 1 is a vertical sectional view showing an embodiment of the present invention. It should be noted that the same or corresponding parts as those of the conventional example of FIG. The characteristic feature of this embodiment resides in the blower outlet 11 of the blower 8 provided in the fan casing 14. That is, by extending the protruding wall 1d downward from the partition wall 1a that divides the inside of the main body case 1 into two parts in the vertical direction, the opening width of the blower air outlet 11 is narrower than in the conventional case. Specifically, the uppermost opening 11a of the blower outlet 11
Is located below the lower surface 2a of the evaporator 2.

The operation of the embodiment configured as described above will be described. When the blower 8 sends cooling air toward the evaporator 2, the blower outlet 11 of the blower 8 is blown from below by the projecting wall 1d. ing. Therefore, the blown cooling air flows along the bottom plate 15, changes its direction at the side wall 1e of the main body case 1, then rises toward the air outlet 1c, and is supplied to the upper part of the steam guide cylinder 7. Get a good flow. Then, the hot air on the outer peripheral side of the evaporator 2 including the heating body 3 is discharged while being drawn into the flow, so that the temperature rise inside the main body case 1 is prevented.

Further, in order to prevent the temperature rise inside the main body case 1 as in the prior art, the evaporator including the heating body 3 is compared with the one in which the cooling air is directly applied to the heating portion to lower the temperature of the portion. The area around the outer circumference can be kept at a higher temperature in this embodiment. Therefore, the heat energy generated by the heating element 3 is more effectively consumed for heating water than before.

Embodiment 2. In the above embodiment, the air outlet 11 of the fan casing 14 is located below the evaporator 2 and the cooling air is not directly applied to the evaporator 2. However, in order to further improve the certainty, As shown in FIG. 2, the partition plate 16 may be provided so as to cover the lower portion and the peripheral edge of the evaporator 2 and the heating body 3. The partition plate 16 is provided at a distance from the evaporator 2, and the upper portion is formed in a dish shape having an opening. By providing this partition plate 16, it is possible to keep the evaporator 2 warm, prevent hot air from diffusing, and prevent the cooling air from hitting the evaporator 2, thus preventing the temperature rise inside the main body case 1 and the energy of the heating element 3. Efficiency is further improved. In the figure, parts that are the same as or correspond to those in FIGS. 1 and 3 are given the same reference numerals, and descriptions thereof will be omitted.

[0012]

As described above, according to the present invention, since the blower outlet of the fan casing is provided below the evaporator, a more reliable cooling air passage is formed and the cooling effect inside the main body case is improved. As a result, the temperature of the components arranged in the main body case can be prevented from rising and the service life of these components can be extended. Furthermore, since the hot air staying around the evaporator is sucked and cooled, the heating body and the evaporator are not cooled more than necessary, and the heat of the heating body can be effectively used for heating water.
