JP 2009-276012 "Electric stove with humidifier"

  In the above-mentioned known technology, when the airframe is tilted, the water surface of the humidification chamber (humidification chamber) and the humidification water receiving chamber (water storage chamber) of the humidifier is displaced toward a part of the fuselage, so that There is a problem that causes abnormal water supply. That is, if the water tank is inclined toward the humidification chamber (humidification chamber), the water supply to the water addition chamber (humidification chamber) is excessively supplied, and the water level below the water tank in the humidification water receiving chamber (water storage chamber) is lowered. An air gap is generated at the discharge port of the tank, and air enters the water tank, resulting in an abnormal water supply state, which may cause water leakage from the edge of the humidifying case and contaminate the floor surface.

  Therefore, this invention makes it a subject to supply water so that the water level of a hydration chamber may be maintained in an allowable range, even if an airframe is inclined in an allowable range.

  According to the present invention, in the electric stove with a humidifier, the water storage chamber 1 is provided with a partition wall 12 having a water receiving groove 4 positioned below the water tank 10 and surrounding the storage space of the tank cap, The chamber 1 is divided into two, and a first water storage chamber 1A having a water receiving groove 4 positioned below the water tank head and a second water storage chamber 1B positioned near the humidification chamber 2 are formed. .

  In the invention of claim 2, in the invention of claim 1, in the first water storage chamber 1A, the first water channel groove 5 that is located in the tank head space and communicates with the water receiving groove 4 is located closer to the periphery. And a second water channel groove 6 is formed in the second water storage chamber 1B, and the second water storage chamber 1A and the humidification chamber 2 of the water storage chamber 1 are communicated with each other via the first water channel groove 5 and the second water channel groove 6. It is characterized by that.

  The invention of the present application prevents the malfunction of the automatic water supply mechanism by maintaining the water level of the water receiving groove of the second water storage chamber of the water storage chamber against the inclination state of the allowable range of the airframe, By preventing a significant change in the water level, water leakage can be prevented and the humidifier can be operated normally.

By blowing the humidified warm air K2 into the room from the wind chamber H3, the humidified warm air is supplied toward the vicinity of the floor in the heating room.

  Hereinafter, the present invention will be described with reference to FIGS.

  In the invention of the present application, the water tank 10 is equipped on the back side of the fuselage in the invention of the prior application, but the invention of the present application is equipped on the side of the fuselage, and the humidification chamber 2 in which the humidification filter 3 is installed is provided on one side of the fuselage. The water storage chamber 1 where water is supplied from the water tank is placed closer to the left side (right side), and the structure of the humidifying device A at the bottom of the body of the prior invention is changed as follows. To do.

  By providing the water storage chamber 1 with a partition wall 12 below the water tank 10 and surrounding the storage space of the tank cap, the water storage chamber 1 is divided into two so that the first water storage chamber 1A and the humidification chamber 2 are closer to each other. A second water storage chamber 1B is formed.

  In the tank head housing space of the first water storage chamber 1A, the lid cap 10A of the water tank 10 can be accommodated, but a projection 9 is formed at the center for contacting the valve mechanism 10B of the lid cap 10A. At the same time, a water receiving groove (annular groove) 4 surrounding the protrusion 9 is formed.

  In the first water storage chamber 1A of the water storage chamber 1, the water receiving groove 4 is formed in the tank head space, and the first water channel groove 5 is formed in the vicinity of the peripheral portion to receive the water. The water groove 4 and the first water channel groove 5 are communicated with each other via the communication water channel 7.

  A second water channel groove 6 is formed in the second water storage chamber 1B. One end of the second water channel groove 6 communicates with the first water channel groove 5 through the window Q, and the other end communicates with the humidification chamber 2 through the window P.

  Therefore, the water receiving groove 4 of the first water storage chamber and the humidifying chamber 2 communicate with each other through the communication water channel 7, the first water channel groove 5, and the second water channel groove 6.

In the embodiment, a water storage detection chamber 11 is provided.
The water storage detection chamber 11 is positioned on the front side of the machine body in the front-rear direction, adjacent to the humidification chamber 2 and positioned on the water storage chamber 1 side.

  The water storage detection chamber 11 communicates with the extension water channel 5a of the first water channel groove 5, communicates with the water reception groove 4 of the first water storage chamber 1A, and is equipped with a float 11a to detect the water level of the water reception groove 4. .

  The tank head housing space is surrounded by the partition wall 12, a part of the peripheral wall of the humidifying water detection chamber 11 (an extension of the partition wall 12) 12 </ b> A, and a part of the peripheral wall 14 a of the humidifying case 14.

  A rear plate 20 is integrally formed behind the humidifying case 14, and the rear plate 20 is pulled out so that the humidifier A can be removed from the electric stove body.

  The humidifier A has a humidifying unit C that can be inserted into the humidifying chamber 2, and the humidifying unit C has a humidifying filter 3, a blower receiving chamber 15, and a hot air outlet chamber 16.

Referring to FIG. 8, water is supplied to the water storage chamber 1 from a water tank 10 provided on the right side of the main body, and water supply at a set water level is maintained in the first water storage chamber 1A.
The humidifying filter 3 of the humidifying unit C is supplied with water through the window P from the water storage chamber 1 at all times. Necessary moisture is supplied.

  Heated air K1 is supplied to the blower receiving chamber 15 from an electric fan (not shown) of the main body, and the heated air K1 passes through the humidifying filter 3 from the blower receiving chamber 15 and then is added with moisture to be humidified. It becomes the warm air K2 and flows out from the warm air outlet chamber 16 from the humidified warm air blowing case 18.

  Therefore, the heated air K1 that has passed through the humidifying filter 3 is supplied to the humidified warm air blowing case 18 as the humidified warm air K2, and as a result, the humidified warm air K2 is blown into the room, so that the heated air K1 is brought near the floor surface in the heating room. To supply humidified warm air.

  In the present invention, the water level of the annular groove of the first water storage chamber is maintained within a certain range even when the airframe is inclined toward the humidifying chamber.

  Referring to FIG. 9 showing a state in which the airframe is inclined toward the humidifying chamber [the right side of the airframe (water tank 11 side is high)], the water level L4 of the annular groove of the first water storage chamber (and the water level L11 of the water storage detection chamber 11). The water level L1A of the first water storage chamber 1A is maintained at a higher level than the water level L2 of the humidification chamber 2 (and the water level L1B of the second water storage chamber 1B).

  Accordingly, no gap is generated in the vicinity of the valve mechanism of the lid cap 10A, and excessive water supply is not generated. Therefore, water leakage from the humidifying case can be prevented.

  The present invention contributes to industrial development such as electric stove manufacturing-related industries and industrial machine manufacturing industries by promoting the use of electric heaters with humidifiers.
