Abstract

PURPOSE:To prevent condensate from dripping from an outlet by forming multiple flat ribs having a fine gap in the inside of the steam outlet on its inner wall and ceiling. CONSTITUTION:When a heater 23 is activated, its heat is radiated directly or after reflected by a reflector 24. At the same time, air blown by a fan motor 27 is delivered out of an air outlet 30 as hot air as it is heated while passing through an air passage 29. Water in a water tank 32 is boiled in a heater 31 to deliver its steam out of an outlet 33 through a guide tube 34, but part of the steam is condensed on the inner wall of the guide tube. Since the water condensed on the inner wall 37 and ceiling 38 near the outlet 33 is guided away into a fine gap (a) formed between multiple flat ribs 39 on account of the capilary action, there will be no large size water droplets near the outlet 33, thereby preventing water from dripping out of the outlet 33.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a humidifying device for an electric fan heater that humidifies by generating steam.

2. Description of the Related Art As shown in FIG. 3, a conventional electric unheater of this type has a heating section 6 and a steam guide tube 3 disposed in the lower part of the interior of a main body 2 having a heater 1. That is, the discharge port 4 is opened in a vertical plane, and the discharge port 4 is connected to the heater 1.
In order to prevent it from being drawn toward the main body due to the influence of rising air currents, the opening area is made into small holes with a constant ratio. 6 in the figure is a stand.

Problems to be Solved by the Invention However, with such a structure, some of the steam rising from the heating section 6 becomes dew water on the inner wall of the guide tube 3 before reaching the discharge port 4, and especially The water droplets formed above the discharge port 4 hang down to the discharge port 4 due to surface tension, thereby reducing the opening area of the discharge port 4. And this discharge port 4
There is a problem in that the water droplets hanging down are discharged as water droplets to the outside of the discharge port 4 due to the internal pressure of the steam, thereby wetting the main body 2 and the stand 6.

The present invention solves these problems and provides a humidifying device for an electric fan heater that has a steam generating section that prevents condensed water from dripping from the discharge port and does not wet the main body or stand. The purpose is to

Means for Solving the Problems In order to achieve this object, the present invention provides a steam generation section within the main body case, and a steam discharge provided on the front surface of the main body case in communication with the steam generation section. An outlet is provided, and a plurality of plate-like ribs are formed inside the steam outlet so as to have minute gaps with respect to the inner wall surface and the ceiling surface of the steam outlet.

Function: With this configuration, water droplets that condense around the discharge port or directly on the ceiling due to the steam generated from the heating section are formed on the plate-shaped ribs, inner wall surface, and ceiling surface as the water droplets grow and become water beads. It penetrates into the small gap created by capillary action and moves downward.

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

As shown in the figure, the main body case 20 is formed into a vertically long cylindrical shape, and has an upper reflective support plate 21 and a lower reflective support plate 2 at its front opening.
A heater 23 is disposed which is held from both the upper and lower sides by means 2. A reflecting plate 24 having a parabolic cross section with the center of the heater 23 as its focus is provided to radiate the heat of the heater 23 forward. A grid-like guard 26 is provided on the front opening side of the main body case 2o to prevent large foreign objects from entering the heater 23, and a stand 26 with a large bottom area is provided on the bottom of the main case 2o to increase the stability of the product. 9 have been taken. A fan motor 27 is installed inside the lower part of the main body case 20, which sucks air through a suction port 28 on the rear surface, and warms the air while passing through an air flow path 29 formed by the main body case 20 and the reflector 24. The case 20 has a structure in which hot air is discharged from a lattice-shaped air outlet 3o at the upper front of the case 20. Similarly, inside the main body case 2°, there are a heating part 31 that generates steam, a water tank 32 that stores water, and a guide tube 34 that guides the generated steam to the discharge port 33 on the front surface of the main body case 2o. They are connected watertight with joints 35 and 36 and housed.

As shown in FIG. 1, the steam guide cylinder 34 is provided with a plurality of plate-shaped ribs 39 so as to have a minute gap d with respect to the inner wall surface 37 of the discharge port 33 and the ceiling surface 38.

Next, the operation in this embodiment will be explained.

When a switch (not shown) is turned on, the heater 23 is energized, and the heat generated by the heater 23 is radiated forward either directly or reflected by the reflector 24. At the same time, the fan motor 27
The air sent is warmed while passing through the air flow path 29 and is discharged from the air outlet 3o as warm air.

Furthermore, when water is placed in the water tank 32, it boils in the heating section 31, passes through the guide tube 34, and is discharged as steam from the discharge port 33, but some of the steam condenses on the inner wall of the guide tube along the way. .

As the operating time becomes longer, the condensed steam becomes water droplets, which are also formed on the inner wall surface 37 and ceiling surface 38 near the discharge port 33, but these water droplets are formed in the minute gaps a formed between the plurality of plate-shaped ribs 39. Since the water enters the water by capillary action, large water droplets do not form around the discharge port 33.

As described above, according to this embodiment, inside the discharge port 33,
By forming a plurality of plate-shaped ribs 39 with minute gaps a on the inner wall surface 37 and the ceiling surface 38, it is possible to prevent water droplets from leaking out from the discharge port 33.

Effects of the Invention As is clear from the above description of the embodiments, according to the present invention, a plurality of plate-like ribs are provided inside the steam discharge port, and minute gaps are formed between the inner wall surface and the ceiling surface of the discharge port. Since this is provided, water droplets around the discharge port among the water droplets condensed on the inner wall are prevented from becoming large water droplets. This is an excellent humidifier for electric fan heaters that prevents large water droplets from dripping from the outlet, eliminates the risk of water droplets being discharged outside the main unit, and does not wet the main unit or stand. It is possible to realize this.
