Abstract

PURPOSE:To improve safety in such a way that a temp. of boiled water flowing out from a blow-off hole is able to be reduced by means of water flowing in a steam pan from a water storage tank when a product is upset by connecting directly the water storage tank to the steam pan with a connecting pipe and also placing a valve mechanism which opens and colses only at the pan side in the midway of the pipe. CONSTITUTION:At the upper end in the front surface side of a water storage tank 8, a connecting part 16 is formed and connected directly with a steam pan 14 through a connecting pipe 17. At this part 16, an open and closed valve 18 opening and closing in the direction of the pan 14 only is placed. When a product is upset in front, boiled water in a steam generating pipe 11 is apt to flow out, but the cold water in the tank 8 pushes the valve 18 to mingle into the pan 14. Therefore, at the outflow from a blow-off hole 15, hot water and cold water are mixed to reduce the water temp. and the generation of dangerousness such as a skin burn etc. is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electric stove with a humidifier, and more particularly to the humidifier.

BACKGROUND OF THE INVENTION Conventionally, as shown in FIG. 3, this type of electric stove with a humidifying device has a case 102 with a built-in vertical heater unit 101 connected to a water storage tank 103 and a water storage tank 103 at the top of the case 102. , a humidifying device 105 such as a steam generating tube 104 that heats and boils water is disposed, and the steam generated from this device passes through a gutter-shaped steam receiver 106 connected to the upper part of the steam generating tube 104, and then flows into the case. 102
The structure was such that the air was discharged from an air outlet 107 provided on the top surface.

Problems to be Solved by the Invention However, with such a conventional configuration, if the product is accidentally knocked over, the boiling water heated by the steam generating pipe 104 will protrude from the outlet 107 and overflow into the room. The liquid splashed onto the chests and knees of people, posing a risk of burns.

The present invention solves these problems and provides a highly safe electric stove with a humidifier that lowers the temperature of water leaking from the outlet when the product falls over, reducing the risk of burns and the like. The purpose is to

Means for Solving the Problem In order to solve this problem, the present invention includes a heater unit and a humidifier, the humidifier including a water storage tank and a steam generating pipe connected to the water storage tank to heat and boil water. and a steam receiver that guides the steam generated in the steam generation pipe to the outside, and the water storage tank and the steam receiver are directly connected by a connecting pipe, and in the middle of the connection, only the steam receiver side is connected. It is equipped with a valve mechanism that opens and closes at different times.

Effect According to the above structure, when the product falls over, the cold water in the water storage tank passes through the connecting pipe, pushes the valve open, and mixes into the steam tray, and flows outward from the outlet along with boiling water from the steam generation pipe. The temperature of the boiling water decreases because the boiling water is discharged at

EXAMPLE Hereinafter, an example of the present invention will be explained based on FIGS. 1 and 2.

Fig. 1 is a cross-sectional view of a main part of the humidifier part of an electric stove with a humidifier according to an embodiment of the present invention, and Fig. 2 is a cross-sectional view of the same electric stove. A vertically elongated case, 2 is a vertical heater unit disposed in the front opening of the case 1, and is supported from both sides by an upper reflective support plate 3 and a lower reflective support plate 4; 5 is a vertical heater unit; A parabolic reflector whose focal point is the center of unit 2, 6
Reference numeral 7 designates a grid-shaped protective guard installed at the front opening of the case 1 to prevent foreign matter from entering the vertical heater unit 2, and 7 a power switch installed on the top of the case 1 to perform important operations.

Next, a humidifying device A is built in the lower part of the vertical heater unit 2, and the configuration of its main parts will be explained in detail based on the drawings. Reference numeral 8 denotes a water storage tank, and the upper end of the case 1 in the rear direction has a water receptacle 9 for water supply and drainage. This water storage tank 8 is
It is connected from the lower end to a steam generation pipe 11 via a joint 10 made of rubber or the like and guided upward. The steam generation pipe 11 is a steel pipe or the like insulated with mica, on which a heater wire 12 is wound. is configured to be connected to an outlet 16 that projects steam to the outside. Further, at the upper end of the front side of the water storage tank 8, another connection part 1e is provided, and the connecting pipe 1
The steam receiving tray 14 is directly connected to the steam receiving tray 14 without passing through the steam generating pipe 11 via the steam pipe 7. In addition,
A steam receiver 1 is connected to the connection portion of the connecting pipe 17 to the steam receiver 14.
An on-off valve 18 that can be opened and closed in only four directions is attached.

Next, the operation of this configuration will be explained. First, when the power switch 7 is turned on, the vertical heater unit 2 is energized, and the heat generated therefrom is radiated forward either directly or reflected by the reflector 5. On the other hand, if the humidification function is also selected,
The humidifying heater wire 12 is energized, and the water in the steam generating tube 11 is heated and boiled, turning into steam and passing through the steam receiving tray 1.
After passing through the air outlet 4, the air is sent out from the air outlet 15. In addition, if the product is accidentally tipped forward, the boiling water in the steam generation pipe 11 will try to flow out, but when the product is tilted, cold water from the stored water will flow through the connecting pipe 17. Press the on-off valve 18 to allow the steam to enter the tray 14 and exit the outlet 15.
When it flows out, rainwater mixes with the water, lowering the temperature of the water and preventing the risk of burns.

Note that the opening/closing valve 18 does not open or close in the direction I- of the steam receiving tray 14 under normal steam generation conditions, and high-temperature steam flows into the connecting pipe 17.
The purpose of this is to prevent harmful effects such as thermal deformation from entering the water storage tank 8 through the steam, and to reduce loss in the amount of steam generated.

In this embodiment, an electric stove with a humidifying device without a fan is explained, but it goes without saying that the same effect can be obtained with an electric stove with a fan-additional humidifying device having a built-in fan motor.

Effects of the Invention As is clear from the above description of the embodiments, according to the present invention, when a product falls over, water from the water storage tank flows into the steam tray and lowers the temperature of the hot water flowing out from the outlet. Therefore, the effect of reducing the risk of burns and improving safety can be obtained.
