Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a humidifier, for example, a humidifier that provides a humidified environment with particulate vapor such as indoor humidification, humidification in a showcase, and humidification for an air conditioner.

(Prior Art) Conventionally required humidifiers include indoor air conditioners during heating and humidifiers for preventing foods such as vegetables, cakes and dairy products from drying. Humidifiers are also used in showcases and the like.

As the humidifying means, there are a means using an ultrasonic vibrator, a means by spraying water, a means by heating and evaporation, and a means by natural evaporation of water by forced convection of air.

In addition, the device using the element having the Peltier effect is actually developed.
There are 56-68895 and Japanese Utility Model Laid-Open No. 61-157432, all of which have been used for keeping cold and moisturizing.

As described above, there are various humidifying, cooling, and warming means, but as a conventional humidifying means, a water evaporation method using a heater or the like is generally used.

However, among the conventional means used for humidifying fresh foods, there are large water particles for humidification and the water is attached to foods, cases, etc. by maintaining humidity to form water droplets. Sometimes it is not suitable for cakes and dairy products.

In addition, the water evaporation method using a heater or the like adversely affects the cooling effect in a showcase or a refrigerator.

Therefore, the inventor of the present invention has previously proposed, as Japanese Patent Application No. 63-128485, a humidifier that eliminates the above drawbacks and enables optimum humidification without impairing the cooling effect.

This is a humidifier that utilizes a Peltier element to heat and evaporate water on the heating side, mix with the cooling air on the cooling side, and discharge.

(Problems to be solved by the invention) According to Japanese Patent Application No. 63-128485, optimum humidification is possible without impairing the cooling effect. However, when the water temperature is low, only natural evaporation power is used. It is difficult to obtain the desired humidification condition.

Further, there is a case where the water temperature is lowered when the current supply to the Peltier element is stopped by the evaporation control, and it is necessary to keep the temperature.

Furthermore, the control of the humidifying state is only the control of the current supply to the Peltier device.

Therefore, the object of the present invention is to provide a humidifier capable of promoting the evaporation effect even when the water temperature is low, and adjusting the humidification state by supplying current to the Peltier device and air supply to the hot water. To do.

(Means for Solving the Problems) The present invention provides the following humidifier in order to achieve the above objects.

That is, in a humidifier that uses a Peltier element to evaporate the water in the heating-side water tank, mix it with the cooling-side cooling air in the cooling side, and discharge it, a part or all of the supply-side air is removed from the heating-side water tank. A humidifier provided with a device for discharging below, wherein the cooling side air in the device for discharging the cooling side air below the water surface of the heating water tank has been heated by a heat dissipation fin around the heating side water tank, The current supply control device for the Peltier element and the air supply device for the heated water tank are humidifiers that are separate control devices.

(Function) It is possible to heat and evaporate water on the heat radiating side of an element having a Peltier effect (hereinafter referred to as Peltier element), and the air cooled on the cooling side of the Peltier element and the heat radiating air and steam on the heat radiating side are mixed. Some or all of the cooling side air is discharged below the water surface of the heating side water tank, or part or all of the cooling side air is heated by the radiation fins around the heating side water tank. After that, it can be discharged under the surface of the water tank to accelerate the evaporation effect and adjust the humidification in combination with the heating state by combining the current supply to the Peltier element and the forced evaporation by the air supply into the hot water.

(Example) First, the description of Japanese Patent Application No. 63-128485 will be given.

As shown in FIG. 4, the humidifier (A) has a support frame (3) on a shelf plate (2) formed inside the exterior body (1), and a Peltier element (4) sandwiched by bakelite (4) It is supported.

A radiating fin (5) and a cooling fin (6) are formed above and below the Peltier element (4), the upper side being the heat radiating side and the lower side being the cooling side.

A water tank (7) is formed on the upper fin side,
A cooling fan (8) is provided on the cooling fin side.

An intake port (9) is formed above the shelf plate (1), and an exhaust port (10) is located above the exterior body (1). A space (14) is formed on the outer peripheries of the Peltier element (4) and the water storage tank (7) in the sense of the exterior body (1) to form one flow path, and therefore, the support frame (3). Has a vent (1). Further, the exterior body (1) has a pedestal (13) having a passage (12) formed therein.

When the Peltier element (4) of the humidifier (A) as described above is energized, the water in the water storage tank (7) is heated and evaporated on the heat radiation side, and the water is taken in from the intake port (9) by the fan (8). The air is cooled by the fins (6) on the cooling side, and the cooled air passes from the ventilation port (11) through the passage (14) to the exhaust port (1).
At 0), the heat radiation side heat radiation air and steam are mixed and discharged here.

Therefore, the cooling of the environment having humidification as the total amount of heat is not hindered.

Then, since the water discharged from the exhaust port (10) is evaporated, the water particles for humidification are fine.

In FIG. 5, a handle (15) is attached to the exterior body (1) so that it can be carried, and a lid (17) is covered via a packing (16). Lid (1
A humidification pipe (18) is formed in 7).

The humidifying pipe (18) sufficiently mixes the cooling air and the humidified air.

The radiating fins (5) and the cooling fins (6) are formed of an aluminum plate, and are supported by the Peltier element (4) through a bakelite (19) or the like on a support frame (3).

In the illustrated example, the Peltier element (4) is not in direct contact with the heat dissipation fin (5) and the cooling fin (6), but it is better to be in direct contact therewith.

As described above, Japanese Utility Model Application No. 63-128485 enables optimum humidification without impairing the cooling effect. However, when the water temperature in the water tank (7) is low, the desired humidification condition can be achieved only by the natural evaporation force. It is difficult to obtain, and it takes time to reach the high temperature that promotes evaporation.

Further, when the current supply to the Peltier element is stopped by the evaporation control, the water temperature may decrease and it may be necessary to keep the temperature.

Moreover, the control of the humidifying state is only the control of the current supply to the Peltier element.

In view of this, the present invention has devised a humidifier capable of promoting the evaporation effect even when the water temperature is low, and capable of adjusting the humidification by supplying a current to the Peltier element and supplying air into the hot water according to the humidified state.

Then, the water is ejected from the nozzle (25) below the water surface of the water tank (7) into the water tank (7). The jet of the cooling air into the hot water of the water tank (7) generates a water flow as well as water bubbles, which contributes to the acceleration of heating of the water and the heating time can be shortened.

Since the current can be supplied to the Peltier element (4) independently, it is possible to adjust the humidification by combining the current supply to the Peltier element and the forced evaporation by the air supply into the hot water according to the humidification state. .

A control valve for the supply flow rate may be provided in a part of the air supply pipe (20).

In the case of FIG. 2, the ventilation port (11) of the support frame (3) is simply an opening (26), and the cooling air discharged from this is provided with a regulating valve (29) of the partition wall (27) from the passage (14). It is discharged into the lid (17) through the bypass opening (28). The cooling air discharged from the bypass opening (28) is heated by the radiating fin (5), is mixed with the steam from the exhaust port (10) and reaches the humidification pipe (18) Control valve (29) A part of the bypass opening (28) with a conduit (2
8 ') is connected to the jet pipe (24) through the joint (30), and the heated cooling air is supplied from the nozzle (25) to the water tank (7).

Therefore, the humidification can be adjusted according to the humidification condition. In addition, although the embodiment does not describe a method of ejecting all the cooling air below the water surface of the water tank,
All of the cooling air may be jetted below the water surface of the water tank.

As described above, the design can be changed arbitrarily within the spirit of the present invention.

(Effect of the Invention) Even when the water temperature is low, the present invention accelerates the evaporation effect by increasing the contact area between the air and the hot water due to the generation of air bubbles due to the jet of air.
