Abstract

PURPOSE:To reduce the flow of the drainage from a heating pipe so as to make the temperature of the drainage discharged from a drainage vent relatively lower by making a heating pipe-draining channel leading from the heating pipe to the drainage vent smaller in diameter than a tank-draining channel leading from a water tank to the drainage vent. CONSTITUTION:When a humidifier is not used for a long time, a stopper 41 is removed from a drainage vent 40 and the water in a water tank 33 and in a heating pipe 36 is discharged. When this drainage is done immediately after the use of the humidifier 31, the boiling hot water in the heating pipe 36 mixes with the water from the water tank 33 and is discharged from the drainage vent 40. Therefore, if a first connecting pipe 37 and a second connecting pipe 38 are about the same in diameter, the temperature of the drainage discharged from the drainage vent 40 is relatively high and the splashes of the drainage feel hot to the touch. Therefore, in this constitution, the first connecting pipe 37 has a part 42 narrowed in a diameter by which the flow of the drainage from the heating pipe 36 is reduced, so that the temperature of the drainage at the drainage vent 40 becomes lower and its splashes are not hot to the sense.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a humidifier that humidifies water using steam generated by heating water.

(b) Conventional technology Conventionally, this type of humidifying device connects a water tank that stores water to a heat generating pipe, and forms a drain port in this connection to connect the water tank and heat generating pipe when not in use for a long period of time. The water in the heating pipe is drained from the drain port, but the tank drain channel from the water tank to the drain port and the pipe drain channel from the heat generating pipe to the drain port are formed to have the same diameter. Therefore, when draining the water in the water tank and the heat generating pipe from the drain outlet, the water in the water tank and the heat generating pipe are mixed equally and drained.

However, since the water in the heat generating pipe is at a high temperature of about 100° C., the water discharged from the drain port has a relatively high temperature, and there is a drawback that it feels hot when you touch the splashing water.

(c) Problems to be Solved by the Invention The present invention has been made in view of the above-mentioned drawbacks, and an object thereof is to provide a humidifying device that can lower the temperature of waste water from a drain port to a relatively low temperature.

(d) Means for Solving the Problems The present invention provides a water tank for storing water, a heat generating pipe connected to the water tank, and a drain port formed at the connection between the water tank and the heat generating pipe. It is characterized in that the pipe drainage channel leading from the heat generating pipe to the drain port is formed to have a smaller diameter than the tank drain channel leading from the water tank to the drain port.

(e) If the humidifier is not used for a long period of time, drain the water in the water tank and heating pipes from the drain port. If this drainage operation is performed immediately after using the humidifier, the boiling water in the heat generating pipe will mix with the water in the water tank and will be drained through the drain port 4o, but the pipe drainage flow path will be connected to the tank drain. Since it is formed to have a smaller diameter than the flow path, the amount of water discharged from the heat generating pipe is reduced, and the temperature of the waste water at the drain port is low, so even if you touch the scattered waste water, you will not feel the heat.

is provided, so that it is efficiently deflected to the heater 18.
The air is guided substantially uniformly over the entire surface, and the heat generated from the entire surface of the heater 18 can be effectively used to heat the air, thereby improving heating efficiency.

In addition, since a ceramic heater is used as the heater 18, the heater 18 does not become red hot even when the heater 18 is energized, making it difficult to confirm the energization state of the heater 18. Since the light emitting part 21 is configured to emit light when the heater 18 is energized, the light emitted from the light emitting part 21 can be confirmed through the wind direction deflection blade 25, and the energization state of the heater 18 can be easily confirmed. This prevents operational errors such as forgetting to turn off the power.

When hot air is not required, the power supply to the ceramic heater 18 can be cut off by operating the heater control switch control part of the switch panel 26, and the air purified by the air purification filter 11 is exhausted from the exhaust port 17, and the so-called Can be used as an air purifier.

When you want to humidify the room, when you operate the humidification control switch operation part of the switch panel 26, the heater wire wound around the outer circumference of the heat generating pipe 36 of the humidifier 31 is energized, and the water inside the heat generating pipe 36 is heated. The steam is turned into steam and discharged from the exhaust port 48, humidifying the room.

At this time, the water in the heat generating pipe 36 becomes boiling, and there is a risk that large bubbles generated in the hot water in the heat generating pipe 36 will float to the surface and burst on the liquid surface, causing the hot water to scatter and eject along with steam. However, since the first cap 45 and the second cap 46 are formed above the heat generating pipe 36 of the saucer 43, hot water will not spout out from the outlet 48 together with steam, and there will be no risk of burns. do not have.

During use, it is possible that the main body 1 may be accidentally tipped over, but if the main body 1 is tipped forward, the connecting part of the first connecting pipe 37 and the second connecting pipe 38 should be connected from the back of the water tank 33. Since it is located at the rear, when the main body 1 falls forward, the connecting part between the first connecting pipe 37 and the second connecting pipe 38 is located at a higher position than the water tank 33, so that the water tank 3
Water in the pipe 3 does not flow out from the discharge 048 via the second connecting pipe 38, the first connecting pipe 37, and the heat generating pipe 36. The first cap 45 formed on the saucer 43 has an opening on the rear side of the main body 1, so that when the main body 1 falls backward, the water level in the heat generating pipe 36 will rise to the first cap.
Since it is not located above the opening of the knob 15, the water in the heat generating pipe 36 will not flow out.

In addition, if the main body 1 is accidentally tipped backwards, the connecting part between the connecting port 35 of the water tank 33 and the second connecting pipe 38 is formed to bulge forward from the front surface of the water tank 33, so that the main body 1 falls backward, the water tank 33 and the second connecting pipe 38
The connection portion with the water tank 33 is located at a higher position than the water tank 33, so that the water in the water tank 33 will not flow out through the second connecting pipe 38, the first connecting pipe 37, and the heat generating pipe 33. Further, since the second cap 46 formed in the saucer 43 has an opening at the front position of the main body 1, when the main body 1 falls backward, the opening of the second cap 46 is lower than the water level in the heat generating pipe 33. part is located upward, and the heat generating pipe 36
The water inside will not flow out.

When the humidifier is not used for a long period of time, the stopper 41 is removed from the drain port 40 and the water in the water tank 33 and the heat generating pipe 36 is drained. When this draining operation is performed immediately after using the humidifier 31, the boiling water in the heat generating pipe 36 mixes with the water in the water tank 33 and is drained from the drain port 40, but the first connecting pipe 37 and the second connecting pipe 38 are approximately the same diameter, the temperature of the waste water discharged from the drain port 40 will be relatively high, and the scattered waste water will feel hot when touched.

However, in this embodiment, the small diameter portion 42 is formed in the first connecting pipe 37 to reduce the amount of water discharged from the heat generating pipe 36, so the temperature of the water discharged from the drain port 40 becomes low, and the scattered waste water You won't feel any heat even if you touch it.

(G) Effects of the Invention As described above, according to the present invention, the pipe drainage flow path from the heat generating pipe to the drain port is formed to have a smaller diameter than the tank drainage flow path leading from the water tank to the drain port. The amount of water discharged from the utility pipe side is suppressed, the temperature of the water discharged from the drain port can be kept at a relatively low temperature, and even if you touch the scattered waste water, you will not feel the heat.
