With this constitution it is possible to supply water from a water supply tank 30 to the wet ball sensor pan 6 and humidifier pan 11A for sure, and the water supply pump can be of a small size. It is, therefore, possible to simplify the whole facilities.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is based on [? The present invention relates to a constant temperature and humidity tank water device, and particularly to a water supply device for a constant temperature and humidity tank that is suitable for unifying the water supply tank and downsizing the water supply pump.

[Conventional technology]

As a conventional technology for a water supply device for a constant temperature and humidity tank,
There is a technique as shown in No.-9338 and FIG.

The conventional technology shown in FIG. 2 includes a housing 1 having a door for one person, a test chamber 2, a temperature and humidity control device 3, a dry bulb 7, a wet bulb sensor 5, and a wet bulb length plate. 6, gauze 7, water supply tank 8, wet bulb sensor water supply pipe 9, humidifier water supply pipe 10,

A water supply solenoid valve 24 provided on the humidifier water supply pipe 10, a drain solenoid valve 25, and a female provided between the makeup water tank 14 and the water supply pump 15.

male socket) 26, 27 and cock 28, and humidifier tray 1
It is provided with a water supply and drainage pipe 29 that connects 1A and a drainage pipe 21.

In the prior art shown in FIG. 2, a replenishment tank 14 is placed on the floor where the constant temperature and humidity tank is installed, a water supply tank 8' ft. 11A is raised by a water supply pump 15 and once put into a water supply tank 8, and from this water supply tank 8 water is supplied to the wet bulb sensor dish 6 and the six humidifying dishes 11A.

[Problem that the invention seeks to solve]

In the conventional technology, the make-up water tank 14 is placed on the floor where the constant temperature and humidity tank is installed, and the water supply tank 8 is installed above the constant temperature and humidity tank, and the design is poor because two water supply tanks are provided. In addition, there were problems in that the equipment cost was high and a large installation space was required.

Furthermore, there is a problem in that it is necessary to take measures to prevent water leakage from the water supply tank 8 installed on the constant temperature and humidity chamber, and the water supply pump 15 also requires a large one, for example, about 201/m.

An object of the present invention is to provide a water supply device for a constant temperature and humidity tank that requires only a single water supply tank and a small water supply pump, and is simple in its entirety and has an excellent design.

[Means for solving problems]

The purpose is to install one water tank higher than the six humidifiers.
This is achieved by installing a water supply tank in which water is supplied to the six humidifying dishes using a positional water head, and water is supplied from the same water supply tank to the wet bulb sensor dish by a water supply pump.

[Effect]

In the present invention, the water supply tank is installed at a position higher than the six humidifying dishes. Then, the six humidifying dishes that consume the most water are supplied with water from the water supply tank using the position water head, and the wet bulb sensor dish that consumes the least amount of water, for example, 5 cc/hour, is supplied with water using the water supply pump. That's what I do.

Therefore, in the present invention, water can be reliably supplied to the six humidifying dishes and the wet bulb sensor dish with one water supply tank, so it is possible to downsize the entire equipment, which improves the design.
Installation space can be reduced.

Furthermore, in the present invention, water is supplied to the wet bulb sensor dish, which consumes less water, using a water supply pump, so a small water supply pump is sufficient.

Therefore, as mentioned above, one water tank is sufficient.
Since a small water supply pump is sufficient, equipment costs can be significantly reduced.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a system diagram showing one embodiment of the present invention.
In the embodiment shown in the figure, the constant temperature and humidity chamber includes a housing 1 having a door made of a heat insulating wall, a test chamber 2 formed inside this, and a control chamber installed outside of this test chamber 2. It is equipped with a temperature and humidity control device 3. The temperature and humidity control device 3 has a cooler, a heater, and a humidifier 11.
Air whose temperature and humidity have been controlled is circulated through the test chamber 2.

Further, a dry bulb sensor 4, a wet bulb sensor 5, a wet bulb sensor 6, and gauze 7 are provided in the upper part of the temperature and humidity control device 3. It is designed to sense and control the temperature and humidity on the constant temperature and humidity chamber. Further, in the lower part of the temperature and humidity control device if3, six humidifying trays 1 are provided.
1A is provided.

On the other hand, a water supply tank 30 is installed at a higher position than the six humidifying dishes 11A. For example, when the height h of the six humidifying trays 11A is h=57 On, the water supply tank 30 is installed at a higher height H=700 m.

Six humidifying dishes 11 that consume a large amount of water from the water supply tank 30
The AK is configured to supply water through the humidifier water supply pipe 10 by utilizing the positional water head. Water is supplied from the water supply tank 30 to the wet bulb sensor dish 6, which consumes less water, through a wet bulb sensor water supply pump 31 and a wet bulb sensor water supply pipe 9't-.

The water level of the wet bulb sensor dish 6 is adjusted by turning off the water supply pump 30 using the wet bulb sensor float switch 12. The water level of the six humidifying dishes + 1A is adjusted by the humidifier float switch 13 and the water supply solenoid valve 24.
This is done by turning ON-OFF. On the other hand, the detection of the water supply tank 30 running out of water is ambiguous because it detects a state in which water is not supplied even if the humidifier float switch 13 detects the lower limit for several tens of seconds. I'm trying to replenish water.

Female and male sockets 26, 27 and a cock 28 are provided so that the water supply tank 30 can be connected to a water supply pipe with one touch.

The overflow water of the wet bulb sensor 6 is discharged to the overflow pipe 18, and the overflow water of the humidifying six tray 11A is discharged to the drain pipe 21 through the overflow pipe 22. The drain water in the test chamber 2 is drained through the drain pipe 23.
Drain water from one door is drained to the drain pipe 23, and water from the wet bulb sensor water supply pipe 9 is drained to the drain pipe 21 by opening the drain valve 33. In addition, humidification 6
Water is drained from the dish 11A through the water supply and drainage pipe 29 by opening the drain valve 32.

Therefore, the water supply tank 30 serves as the water supply tank 8 and the makeup water tank 14 in the prior art, and also serves as the water supply pipe 16 connecting the water supply tank 8 and the makeup water tank 14 in the prior art, and the water supply tank 8 and the makeup water tank 14 in the prior art. Float switch 17 is unnecessary and has been removed.

According to this embodiment, it is possible to reliably supply water from one water supply tank 30 to the wet bulb sensor dish 6 and the six humidifying dishes 11A. Trouble caused by water leakage from the water supply tank can be prevented.

In addition, in the conventional technology, the water supply pump needed to be large, for example, about 201/m2, but in this embodiment, the humidifier 6
A small device of about 5cc7'hour that can supply water only to the dish 11A is sufficient.

〔Effect of the invention〕

According to the present invention described above, the water supply tank is installed at a higher position than the six humidifying dishes, water is supplied from this water tank to the six humidifying dishes using the position water head, and the wet bulb sensor is supplied from the water tank to the six humidifying dishes. Water is supplied to the dish by a water pump.
Since one water supply tank can reliably supply water to the wet bulb sensor dish and six humidifying dishes, the entire equipment can be summarized in a simple manner, which has the effect of improving the design and reducing the installation space. This has the effect of eliminating problems caused by water leakage that occur when the water supply tank is installed on a constant temperature and humidity tank.

Furthermore, according to the present invention, water is supplied from the water supply tank to the six humidifying dishes that consume a large amount of water by using the position water head, so the water supply pump is used to supply water to the wet bulb sensor dish that consumes less water. Since only a small tank capable of supplying water is sufficient, combined with the fact that only one water supply tank is sufficient, the equipment cost can be significantly reduced.
