Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a steam humidifier for humidifying a room by utilizing steam generated by heating the heater.

[0002]

[Prior art]

 Conventionally, in this type of equipment, a heating tank that stores a fixed amount of water supplied from a water supply tank is heated by a heating heater to generate steam, and this is used as a guide tube. The vapor was discharged into the room through the upper steam discharge port, and the room was humidified by the steam.

[0003]

[Problems to be solved by the device]

 By the way, in this conventional type, the water receiving tank and the heating tank are separated, and both are connected by a communication pipe, and high temperature hot water heated in the heating tank flows back into the water receiving tank and enters the water supply tank. In order to prevent this, there is a drop between the two so that the heating tank is above the water receiving tank. In this state, the communication pipe below the heating tank and the bottom plate of the main body below the communication pipe are located. There was a space between the heating tank and the heating tank, and there was concern that the water would overflow due to the disconnection of the communication pipe.

[0004]

[Means for solving problems]

 This invention focuses on this point and solves the above-mentioned drawbacks. In particular, the structure is designed to generate steam by heating a heating tank that stores a certain amount of water supplied from a water supply tank with a heater to generate steam inside the room. A steam humidifier for humidifying, characterized in that a communication pipe support leg is provided below a communication pipe tightened by a connection band at a lower portion of the heating tank, and the communication pipe is supported and fixed.

[0005]

[Action]

 The communication pipe 6 is tightened to the inflow port 5 at the lower part of the heating tank 2 by the connection band 27, and the communication pipe 6 is further supported and fixed in the space formed between the communication pipe 6 and the bottom plate 28 of the main body to communicate with the inflow port 5. It is possible to reliably prevent disconnection of the pipe 6.

【Example】

 Next, a steam humidifier according to the present invention will be described with reference to a preferred embodiment shown in the drawings. Reference numeral 1 is a flat oval instrument body made of synthetic resin. In the center, a heating tank 2 is provided with a bottomed tubular shape and the inner surface of the aluminum material is subjected to decalcification treatment with Teflon and the like. A heating heater 3 made of a planar band heater is fixed to the outer periphery of the side wall of the heating tank 2, and a certain amount of water stored inward is heated to generate a steam. is there.

Reference numeral 4 denotes a water receiving tank which communicates with an inflow port 5 formed at the bottom of the heating tank 2 through a communication pipe 6, and a valve element (not shown) in a water supplying section 8 of a cartridge type water supplying tank 7. ) Is provided, and makeup water from the water supply tank 7 is supplied to the heating tank 2. The water supply tank 7 is made of a transparent synthetic resin and has a donut shape with a hollow central portion as well as its internal volume can be seen at a glance.

Reference numeral 10 denotes a guide cylinder made of transparent synthetic resin that stands upright on the heating tank 2 and is housed in the cavity of the water tank 7 when the water tank 7 is attached. The lower end of the cylinder 11 is airtightly communicated with the inside of the heating tank 2 through the packing 12 to form a steam flow passage 13 for guiding the steam upward, and the outer periphery thereof is provided in the instrument body 1. An airflow passage 16 is configured to allow the air from the blower 14 to flow through the two blower towers 15.

Further, a lower end flange portion 17 that spreads outward is formed at both lower ends of the guide cylinder 10 in the lateral direction, and the lower end flange portion 17 is provided with two left and right protrusions 18 protruding upward. When the water supply tank 7 is attached to the instrument body 1 via the projection 18, the water supply tank 7 presses the lower end of the guide cylinder 10 against the heating tank 2 to maintain a good airtight state.

Reference numeral 19 is a blow-out nozzle mounted on the upper end of the guide cylinder 10. Inside the steam nozzle, the steam flowing through the steam flow passage 13 and the air flowing through the air flow passage 16 are provided. Is mixed and discharged from the air outlet 21 having the guide piece 20 into the room.

Reference numeral 22 denotes an intake port formed on the side wall of the appliance body 1 for intake of indoor air by driving the blower 14. Reference numeral 23 denotes an operation unit, which is provided with an operation switch 24 and an automatic humidity control switch 25 that automatically maintains a constant humidity by ON / OFF control. Reference numeral 26 is a communication pipe support leg extending below the connecting portion between the heating tank 2 and the communication pipe 6, which is integrally molded with the rubber communication pipe 6 and reaches the bottom plate of the main body to support and fix the communication pipe 6. is there. Reference numeral 27 is a connection band for tightening the communication pipe 6 which communicates with the water receiving tank 4 and the inflow port 5 in the lower portion of the heating tank 2. 28 is a main body bottom plate.

Next, the operation of this embodiment will be described. Now, in order to humidify the room, water is supplied to the water supply tank 7 and attached to the main body 1. The water supplied by mounting the water supply tank 7 drops into the water receiving tank 4 and is supplied to the heating tank 2 through the communication pipe 6. Then, after being heated by the heater 3, the steam flow path 13 rises, the air blows from the blower 14 through the blower tube 15 and the guide tube 10 is mixed with the rising air in the blowout nozzle 19, and then the guide piece 20 is provided. The air is blown out into the room through the air outlet 21 to humidify the room.

In addition, at this time, in order to prevent the hot water heated by the heater 3 and heated to a high temperature in the water receiving tank 4 and the heating tank 2 from flowing backward from the heating tank 2 and entering the water supply tank 7, there is a drop between them. Is provided so that the heating tank 2 is located above the water receiving tank 4, the communication pipe 6 is tightened to the inlet 5 at the bottom of the heating tank 2 with the connection band 27, and a space formed between the heating tank 2 and the main body bottom plate 28 is formed. By providing and fixing the communication pipe support leg 26, disconnection between the inflow port 5 and the communication pipe 6 can be reliably prevented.

[0014]

[Effect of device]

 In short, this invention is a steam humidifier that heats a heating tank 2 that stores a fixed amount of water supplied from a water supply tank 7 with a heating heater 3 to generate steam to humidify the interior of the heating tank 2. A communication pipe supporting leg 26 is provided below the communication pipe 6 tightened by a connection band 27, and the communication pipe 6 is supported and fixed to connect the connection between the inflow port 5 and the communication pipe 6 under the heating tank 2. In addition to the conventional structure in which the band 27 is tightened, the communication pipe 6 can be supported and fixed more reliably, and water can overflow due to disconnection of the communication pipe 6 with a simple structure. It can be prevented, and further, the communication pipe 6 and the communication pipe support leg 26 or the bottom plate of the main body 1 and the communication pipe support leg 26 are integrally molded, so that the production is easy and the productivity is low. We like and high cost also is obtained an extremely small reliable effect.
