Description

[Detailed description of the invention] <Industrial application field> The present invention relates to a partition structure of an environmental test chamber for testing the durability or deterioration of various products in high- or low-temperature atmospheres. .

<Prior Art> Environmental test chambers are used to test various parts of automobiles for durability, etc., depending on temperature. As shown in FIG. 4, this environmental test chamber is designed to provide a high or low temperature atmosphere in the environmental test chamber 1 having a required area using air conditioners 2a and 2b.

Since most of the test items are generally small, the environmental test chamber 1 is partitioned by a partition wall 3 into two chambers 1a and 1b on the left and right in order to save energy.

There are two types of partition wall 3: a fixed type and a removable type. Apart from fixed type bulkheads, removable type bulkheads are effective when testing large products, but there is a problem in storage when the bulkhead 3 is removed. Furthermore, when testing large products and small products alternately, it is not only difficult to install and remove the partition wall 3, but also requires the troublesome work of caulking the surrounding gaps each time the partition wall 3 is installed. .

Furthermore, if this caulking is insufficient, air leakage will occur between the left and right chambers 1a and 1b, causing one chamber to
When chamber a is tested at a high temperature and the other chamber 1b is tested at a low temperature, the temperature efficiency of both chambers deteriorates. In particular, when moisture enters a room at a low temperature, frost forms on the fans of the air conditioners 2a and 2b, which significantly reduces the refrigerating capacity.

<Means for solving the problems> The present invention provides a partition structure that improves the above problems, and its characteristic configuration is that the central part of the room surrounded by the outer wall is surrounded by a partition wall. In an environmental test chamber partitioned into left and right chambers, each of which is heated to high and low temperatures by an air conditioner, one end of a pair of partition walls that can be folded like a folding screen with a hinge is used. A hinge is placed on the inner wall of the environmental test chamber at a certain interval so that when folded, the partition wall surface is parallel to the inner wall of the environmental test chamber, and when expanded, there is a space between the opposing surfaces in the center of the chamber. The ventilation fan is rotatably mounted at a position that divides the room into left and right parts, and is equipped with a ventilation fan that keeps the space at room temperature at all times.

<Function> With the above configuration, the room can be divided or expanded by folding and unfolding the partition walls, and when partitioning, the space between the pair of partition walls is forcibly made into a normal temperature space layer by the ventilation fan, so that the left and right sides can be separated. Prevent moisture and heat from moving into the room.

<Example> Hereinafter, an example of the present invention will be described based on FIGS. 1 to 3. In FIG. 1, 1 is an environmental test chamber, and 2a and 2b are air conditioners.

In the present invention, the partitions of the environmental test chamber 1 have the following structure. That is, as shown in FIGS. 2 and 3, a pair of partition walls 4a and 4b that can be folded into a folding screen shape with a hinge 10 have a space 5 on the parallel opposing surfaces, and one end is connected to the environmental test chamber 1. It is equipped with a ventilation fan 6 which is hinged to the inner wall with a hinge 11 and keeps the space 5 at normal temperature.

The reference numeral 8 is the main entrance/exit door of the environmental test chamber 1, and 9 is the door that becomes the entrance/exit of the right chamber 1b when it is divided into the left and right chambers 1a and 1b. 7
is an intermediate pillar that is removably installed in the center of the space 5, and serves as a support when the partition walls 4a and 4b are expanded and partitioned, and secures the space 5, but it must be installed. It's not a must.

Since the present invention has the above-described structure, when dividing the environmental test chamber 1 into left and right chambers 1a and 1b as shown in the figure, the partition walls 4a and 4b are deployed. As a result, a space 5 is formed on the opposing surfaces of the parallel partition walls 4a and 4b. Then, the ventilation fan 6 is operated to keep the space 5 at room temperature. Therefore, a room temperature air layer is formed in the space 5, and this is the space between the left and right chambers 1.
It performs a blocking action to prevent the movement of moisture, heat, etc. between a and lb.

In addition, when testing a large product that uses the entire environmental test chamber 1, the partition walls 4a and 4b should be attached to the hinges 1.
The left and right chambers 1a,
1b communicates with each other to form a large-area chamber.

<Effects of the invention> As described above, the environmental test chamber partition structure according to the invention is a partition wall that can be folded and expanded. can be stored in

In addition, this partition wall is composed of a pair, and when partitioned, a space is formed on parallel opposing surfaces, and this space is forced to always be at room temperature by a ventilation fan, so this room temperature air layer This prevents the movement of moisture and heat between the left and right chambers, provides a sufficient shutoff function without using caulking or sealing pads, and has the effect of saving energy.
