Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a ventilation humidifier capable of releasing a large amount of steam by gently blowing the heated water surface.

[0002]

[Prior Art]

 As a humidifying device of this type, there has been a device described in Japanese Utility Model Laid-Open No. 58-141122, for example. In this conventional technique, an air blowing mechanism is provided at one end of a box-shaped nozzle chamber, a blowout duct is provided in communication with the upper surface near the other end of the nozzle chamber, and vapor is discharged by facing the lower part of the blowout duct. The humidifying device is configured such that by disposing the pipe open, the steam that has passed through the steam outlet pipe is ejected to the blow-out duct by a negative pressure based on the air flow by the blower mechanism.

[0003]

[Problems to be solved by the device]

 In the conventional technique described above, the steam outlet pipe of the heating water humidifier installed in the closed room is installed so as to face the lower part of the blowing duct, so that the vapor phase part above the water surface in the humidifier is installed. Does not pass an air stream, saturated steam stays right above the water surface, which hinders evaporation and is inefficient. In addition, there is a problem that clean humidification cannot be performed due to the large degree of air flow pollution.

In order to eliminate the above-mentioned problems, the present invention uses an air flow generated in a bypass pipe connected to both sides of a duct in a gas phase portion of a heated water humidifier with a fan in a ventilation duct interposed therebetween. The purpose is to moisturize a large amount by actively blowing the airflow and blowing the water gently without using other motor fans.

[0005]

[Means for Solving the Problems] The above-mentioned object of the present invention is to provide a bypass pipe in communication with the duct with a blower fan in the blower duct interposed therebetween, and to connect the air of the heating water humidifier in the middle of the bypass pipe. This can be achieved by connecting the phase parts in series.

[0006]

[Action]

 Due to the air flow in the duct due to the blower fan in the blower duct, the air pressure distribution in the duct across the fan becomes negative than atmospheric pressure on the air intake side of the fan, and lower than atmospheric pressure on the air discharge side of the fan. As a result of the positive pressure, an air flow in the opposite direction occurs in the bypass pipe with respect to the air flow in the duct.

[0007] Therefore, the vapor generated in the vapor phase portion in the upper part of the heated water type humidifier can blow water vapor just above the water surface to promote evaporation, and this vapor is generated in the bypass pipe by the above-mentioned air current, and thus the fan The air enters the duct on the suction side, passes through the discharge side of the fan, and blows air into the room from the air supply port of the duct to humidify the room.

[0008] Since the water surface in the gas phase portion is constantly covered by the airflow flowing in and out through the bypass pipe, a large amount of water vapor evaporates by gently evaporating the water vapor immediately above the water surface and evaporating a large amount of water vapor. Even if the water inside the vessel is heated to near 100 ° C with a heater, etc., the latent heat of evaporation lost from the surface of the heated water can cool the heated water, and even if it is heated to the maximum, large bubbles are not generated and the water surface is quiet. You can heat the water as much as possible and perform efficient humidification.

Further, since a large amount of water vapor can be evaporated by gently blowing the water surface as described above, it is possible to prevent air flow pollution such as calculus fine particles and pollution in the bypass pipe due to the evaporation of the scaly components in boiling water. We were able to achieve extremely clean humidification.

【Example】

 Examples will be described with reference to the drawings. First, as shown in FIG. 1, the basic structure of the present invention is to provide a well-known blower duct 1 made of a metal plate or the like with a motor m having a blower fan 2 such as a propeller fan or a sirocco fan via a stay 2a. A bypass pipe (3) is provided in communication with the duct (1) with the blower fan (2) interposed therebetween.

The gas phase part 4a of the heated water type humidifier 4 is connected in series in the middle of the bypass pipe 3 via a pipe joint 3a to construct a blower humidifier according to the present invention.

In FIG. 1, reference numeral 5 indicates a water supply valve of a well-known float F such as a ball tap type, reference numeral 6 indicates a water supply pipe, h indicates a water heater such as a sheath heater, and 3b and 3c indicate steam. It is an outlet hole and an auxiliary pipe for airflow intake.

The configuration of the device of the present invention is as described above, and the operation of the usage example will be described below. Due to the air flow in duct 1 due to blower fan 2 in blower duct 1, the air pressure distribution in duct 1 with fan 2 sandwiched becomes a negative pressure than the atmospheric pressure on the air intake side of fan 2, and the air discharge of fan 2 As a result of the pressure being higher than atmospheric pressure on the side, an air flow in the opposite direction as shown by the arrow in FIG. 1 is generated in the bypass pipe 3 with respect to the air flow in the duct 1.

Therefore, the steam generated immediately above the water surface can be boiled by the air flow generated in the gas phase part 4 a in the upper part of the heated water type humidifier 4 to promote evaporation, and the steam generated in the bypass pipe 3 The airflow enters the duct 1 on the suction side of the fan 2 and blows air into the room through the air outlet 1a of the duct 1 via the discharge side of the fan 2 to humidify the room.

Since the water surface in the gas phase portion 4a is constantly covered with the airflow flowing in and out through the bypass pipe 3, a large amount of water vapor is evaporated by gently evaporating the water vapor immediately above the water surface, Even if the water w in the humidifier 4 is heated to near 100 ° C. by the heater h etc., the heating water can be cooled by the latent heat of vaporization lost from the water surface of the heating water, and large bubbles will not be generated even if it is heated to the maximum. You can perform efficient humidification by heating the water as much as possible while the water surface is quiet.

Since a large amount of water vapor can be quietly evaporated on the water surface as described above, it is possible to prevent air pollution such as fine particles of scaly powder due to fly-off evaporation of the scaly component in boiling water and fouling in the bypass pipe 3 for extremely clean It was possible to achieve proper humidification.

[0017]

[Effect of the device]

 Since the present invention is configured as described above, it has the following effects. Due to the air flow in duct 1 due to blower fan 2 in blower duct 1, the air pressure distribution in duct 1 with fan 2 sandwiched becomes a negative pressure than the atmospheric pressure on the air intake side of fan 2, and the air discharge of fan 2 As a result of the pressure being higher than atmospheric pressure on the side, an air flow in the opposite direction is generated in the bypass pipe 3 with respect to the air flow in the duct 1.

Therefore, the vapor just above the water surface can be boiled by the air flow generated in the gas phase portion 4 a in the upper part of the heated water type humidifier 4 to promote evaporation, and this vapor is generated in the bypass pipe 3. The airflow enters the duct 1 on the suction side of the fan 2 and blows the air into the room through the air outlet 1a of the duct 1 via the discharge side of the fan 2 to humidify the room. Since there is no need for a fan source such as a dedicated motor fan for sending the airflow inside, there is a first effect that it can be implemented in a small space, in a small size and at a low cost.

Since the water surface in the gas phase portion 4a is constantly covered by the airflow flowing in and out through the bypass pipe 3, a large amount of water vapor evaporates by gently evaporating the water vapor immediately above the water surface, Even if the water w in the humidifier 4 is heated to near 100 ° C. by the heater h etc., the heating water can be cooled by the latent heat of vaporization lost from the water surface of the heating water, and large bubbles will not be generated even if it is heated to the maximum. The second effect is that the water can be heated as much as possible while the surface of the water is quiet, and efficient humidification can be performed.

Further, since a large amount of water vapor can be evaporated by gently blowing the water surface as described above, it is possible to prevent air pollution such as fine particles of scaly powder and pollution in the bypass pipe 3 due to evaporation of the scaly components in boiling water. The third effect is that extremely clean humidification was achieved.
