Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric stove humidifier for heating water by a heater.

[0002]

2. Description of the Related Art It is said that the use of an electric stove in winter reduces the humidity in a room, and when the humidity becomes about 50%, it is easy to catch a cold.

[0003] For this reason, a humidifier has been commercialized, which heats and evaporates water to give an appropriate amount of moisture to a room.

This humidifier has been developed as a dedicated device and is used by placing it on a table or floor in a room. However, the period of use overlaps with the electric stove and the number of outlets for existing outlets is limited. There was a drawback that it was not used, or that the installation space became large and the living space became small.

For this reason, an integrated humidifier and electric stove has been proposed, for example, in Japanese Utility Model Application Laid-Open No. 5-66440, and such an embodiment has been commercialized.

[0006]

However, the humidifying device disclosed in the above-mentioned prior art is provided integrally in the casing of the electric stove, but the humidifying device has a structure in which water is stored in the lower part. A heating pipe fitted with a heater,
It consists of a steam spout at the top of this pipe,
The water heated by the heater becomes steam and is discharged into the atmosphere from the steam jetting part.

In recent years, since a sufficient humidifying function has been required, the amount of water (water storage) in a heating pipe is increased in order to increase the amount of generated steam.
In addition, since the power consumption is about 250 W to 300 W and the steam generation time is shortened so that a large amount of steam is blown out, there is a danger of burns if hot steam is blown out from the steam blowout part and touches it erroneously. Was.

According to the present invention, a large amount of steam is generated and ejected in a short time, but the steam is diffused by lowering the temperature of the steam and preventing the steam from being spouted vigorously in one direction.

[0009]

SUMMARY OF THE INVENTION The present invention provides a fan, a heater for converting the air blown by the fan into warm air, a heating pipe having an open upper end and serving as a steam jetting section, and a comparatively large heating pipe. A humidifier having a heater attached to the lower outer wall, and a baffle plate is provided in the heating pipe at a position close to the steam jetting portion.

Further, the baffle plate has a spiral shape.

Further, the peripheral circuit formed by the baffle plate is provided with a wind guide port for taking in air blown by the fan and blowing it.

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a sectional view of a main part of an electric stove humidifier showing an embodiment of the present invention, FIG. 2 is a side view of the electric stove, FIG. 3 is a front view of the electric stove with a front cover removed, and FIG. FIG. 2 is a detailed view of FIG. 1.

(1) a hot air type electric stove body,
(2) is a housing composed of a front cover (4) having a discharge port (3) at a lower portion and a rear cover (6) having intake ports (5) (5)... (7) is an internal space (7) of the housing. 8) a heater having a positive characteristic that is long in the horizontal direction and is fixed to the discharge port (3), facing the discharge port (3); and (9) a wind tunnel communicating between the intake port (5) and the discharge port (3). In the motor (1
0) a fan (11) that is rotated by
With the rotation of the fan, the air taken in from the intake port (5) is converted into warm air by the heater (7) through the wind tunnel and is discharged from the discharge port (3). (12) is an air outlet provided in a part of the wind tunnel (9) before reaching the heater (7).

A water storage tank (13) is detachably provided at a relatively front side of the internal space (8) of the housing (2).

A humidifier (14) is disposed on one side of the internal space (8) of the housing (2). Although not shown in detail, a copper heating pipe communicated with the bottom of the water storage tank (13). (15), an upwardly expanding steam ejection portion (16) provided at an opening at the upper end of the heating pipe, and a heater closely attached to an outer wall at a relatively lower portion of the heating pipe (15). (17) a drain knob (18) detachably attached to the opening at the lower end of the heating pipe (15) for cleaning and draining the inside of the heating pipe; and steam spouting in the heating pipe (15). And a baffle plate (19) attached to a position near the part (16).

As shown in FIG. 1, the baffle plate (19) is formed in a spiral shape having a peripheral circuit (20) formed thereon, and the steam ejection portion (16) is located above the peripheral circuit.

A relatively large upper portion of the peripheral circuit (20) is provided with a wind guide port (21) which communicates with the outlet (12) and takes in air blown by a fan (11).
(22) is a wind guide pipe connecting the outlet (12) and the wind guide port (21).

Next, the operation will be described. When an electric stove is used, the heater (7) and the motor (10) are energized to guide the air taken in from the intake port (5) through the wind tunnel (9). The air is sent to (7), converted into warm air, and discharged from the discharge port (3).

Here, when the room is given an appropriate humidity, the humidifying knob (not shown) is operated to operate the heater (14).
To heat the heating pipe (15). The water in the water storage tank (13) is injected into the heating pipe, and the water in the heating pipe is heated by the heat generated by the heater (14) to become steam, and rises as shown by the arrow in FIG.

The steam which has risen enters the peripheral circuit (20) of the baffle plate (19) and is decelerated, and the wind generated by the fan (11) flows from the outlet (12) to the wind guide pipe (2).
Through 2), it enters the peripheral circuit (20) through the air guide port (21) to lower the temperature of steam.

[0021]

As described above, according to the present invention, since the baffle plate is provided at a position near the steam jetting portion in the heating pipe for generating steam, the steam rising vigorously in the heating pipe is a baffle plate. Will be decelerated and dispersed to reach a wide area. In particular, since the residence time of steam is prolonged due to the baffle plate, the temperature is reduced by the baffle plate and peripheral members, and burns can be prevented.

Further, since the baffle plate has a spiral shape, it does not suppress steam squirting more than necessary, but rises along the spiral shape, so that steam having a better squirting speed and a better temperature is provided. Can be spouted in large quantities.

The peripheral circuit formed by the baffle plate is provided with a wind guide port for taking in air from a fan that blows to the heater. Therefore, while the temperature of steam is lowered by this air, steam is forcibly ejected by this air. And the temperature of the surrounding members can be reduced.
