Description

Description: TECHNICAL FIELD The present invention relates to a door dew receiving device that receives dew generated on an inner surface of a door that opens and closes a main body opening of an environmental test device such as a thermo-hygrostat.

[Conventional technology]

Taking the constant temperature and humidity chamber as an example, when the inside of the chamber is controlled to, for example, high temperature and high humidity, dew condensation usually occurs on the inner surface of the door.

Therefore, in a thermo-hygrostat, generally, a dew pan is fixed to the main body at a position below the door when the door is closed,
When the door is opened, dew flowing down the inside of the door will fall on this bread.

[Problems to be solved by the invention]

However, when the door is opened, the inner surface of the door is hardly fully opened after the dew on the inner surface of the door has sufficiently fallen into the dew pan, and is fully opened before the dew on the inner surface of the door has sufficiently dropped on the dew pan. Usually it is.

Therefore, when the door is opened, there is a problem that dew drops on the floor surface in front of the thermo-hygrostat and gets wet, thereby deteriorating the working environment.

As a method for solving such a problem, a method is conceivable in which a dew receiving pan is provided at the lower end of the door and the pan is connected to the main body side by a drain pipe. A portion for accommodating the receiving pan must be formed on the main body side, and there is a problem that the opening and closing of the door may cause the drainage pipe to be twisted, broken, a drainage pipe connection part to be disconnected, and the like.

Furthermore, when dew is to be led to the main body side by the drain pipe from the dew receiving pan provided on the door in this way, the water accumulated in the dew receiving pan is not always immediately guided to the main body side. In some cases, the water is led after the water accumulates, in which case the water accumulated in the bread may spill. In addition, such dew pans (which must be box-shaped) and drainage pipes have the problem of being extremely unsightly in appearance.

Therefore, the present invention is a door dew receiving device that receives dew generated on an inner surface of a door that opens and closes an opening of an environmental test device main body,
It is an object of the present invention to provide a door dew receiving device that has sufficient reliability to receive dew flowing down from the inner surface of the door when the door is opened, and that has a good appearance in terms of compactness as a whole.

[Means for solving the problem]

In order to achieve the above object, the present invention is a door dew receiving device that receives dew generated on an inner surface of a door that opens and closes an opening of an environmental test device main body, and is provided on the main body at a position below the door when the door is closed. Body dew receiving portion, below the inner surface of the door, and
It is arranged above the main body dew receiving portion, and can be stowed in front of the inner surface of the door together with the door opening to take a dew receiving posture.When the door is closed, it is pushed under the door due to resistance from the main body side and stored. At least one dew receiving member provided for the door, and slidably contact the upper surface of each of the dew receiving members, and flush the dew on each of the dew receiving members together with the door to the main body dew receiving portion. To get the door,
Alternatively, the present invention provides a door dew receiving device, comprising: a door and a dew-off member provided on each of the members above the lowest one of the door and the dew receiving member.

(Operation)

According to the apparatus of the present invention, when the door is opened, the dew receiving member projects stepwise in front of the inner surface of the door, takes a dew receiving position, and moves with the door.

Therefore, the dew flowing down from the inner surface of the door is received by the dew receiving member, and is prevented from falling to the surroundings.

The dew accumulated in the dew receiving member as described above, when the door is closed, the dew receiving member receives resistance from the main body side and is pushed under the door and stored, so that the dew receiving member slidably contacts the upper surface of each dew receiving member. The dew-off member relatively moves to the main body side, and pushes the dew on the dew receiving member into the main body dew receiving portion provided on the main body to drop.

〔Example〕

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The embodiments described below are all for receiving dew on the inner surface of the thermo-hygrostat door.

FIGS. 1 to 4 show one embodiment, FIG. 1 is a perspective view showing the thermostat / humidifier body and a door, FIG. 2 is a plan view showing the same together with a door, and FIG. FIG. 4 is an explanatory diagram of the operation.

The door dew receiving device includes a main body dew receiving part 1, a dew receiving member 2, and a dew opening member 3 fixed to the lower surface of the door 9.

The main body dew receiving portion 1 is formed in a box shape having an open upper surface, extends over substantially the same width as the horizontal width of the thermo-hygrostat main body 8, and is fixed to the lower front end of the main body 8.

In addition, the position of the dew receiving portion 1 is below the door 9 when the door 9 is closed.

The exposure receiving member 2 is a rectangular plate-shaped member, and extends substantially in parallel with the lower surface of the door 9 over substantially the same width as the width of the door 9. The member 2 is disposed below the door 9 and above the main body dew receiving portion 1, and one end is rotatably connected to the main body 8 and the door 9 by a shaft 91 in the same direction as the door 9. ing.

The shaft 91 supports the door 9 on the thermo-hygrostat main body 8 and is rotatably connected to the main body 8.

An arc-shaped long hole 21 centering on the rod shaft 91 is provided in the middle of the dew receiving member 2, and a rubber plate 22 for water leakage and waterproof is provided on the lower surface of the member 2 so as to cover the long hole. Adhesively fixed.

A cut line 22A is provided in the rubber plate so as to face the long hole 21, and a pin 23 penetrating this cut line from below the rubber plate is screwed to the lower surface of the door 9.

Therefore, the dew receiving member 2 can move the door pivot shaft 91 within a range restricted by the long hole 21 and the pin 23 passing therethrough.
Can be pivoted around the center of the door 9 and fit under the lower surface of the door 9;
As shown in FIG. 1 and FIG. 2, a dew receiving position that protrudes in a step-like manner ahead of the door inner surface 92 can be taken.

A notch 24 is provided at the front of the free end of the exposure receiving member 2, and a catch 25 is provided on the lower surface of the member along the notch.

The catch 25 is made of a resilient synthetic resin material and has a planar shape as shown in FIG. 3, and is a forked member which can be detachably engaged with a lock pin 82 provided at a lower end portion of the front surface of the thermo-hygrostat body 8. It has 251.

The lock pin 82 is provided at a position where the lock pin 82 fits into the notch 24 of the member 2 when the dew receiving member 2 rotates toward the main body 8.

The dew-off member 3 is provided on the lower surface of the door 9 so as to extend over substantially the entire width of the door, and its position is on the front side of the door with respect to the pins 23.

The dew-off member 3 is slidably in contact with the upper surface of the dew-receiving member 2.

According to the above-described door dew receiving device, when the door 9 is in the closed position, the notch 24 of the dew receiving member 2 fits into the lock pin 82 on the main body side, and the forked portion 251 of the catch 25
Is releasably engaged with the lock pin 82 by its elasticity.

On the other hand, the pin 23 screwed to the lower surface of the door 9 is in contact with one end surface 21a (the surface on the main body 8 side) of the long hole 21 of the exposure receiving member 2.

 Thus, the dew receiving member 2 is stored under the door 9.

When the door 9 is opened in this state, initially, the catch 25 remains engaged with the lock pin 82, only the door 9 starts to rotate, and the pin 23 on the lower surface of the door 9 is 21b
To

When the door 9 is further opened after the pin 23 contacts the slot end surface 21b, the pin 23 pulls the exposure receiving member 2 in the opening direction, and the catch 25 is detached from the lock pin 82. Thus, as shown in FIG. 2, the dew receiving member 2 assumes a dew receiving position protruding in a stepped manner in front of the inner surface 92 of the door 9.

Thus, the dew flowing down the inner surface of the door is received on the dew receiving member 2, and is prevented from falling on the floor on which the constant temperature and humidity chamber is installed.

Next, when the door 9 is closed, the exposure receiving member 2 also rotates toward the main body 8 together with the closing rotation of the door 9. At this time, door 9
Since the pins 23 on the lower surface receive the resistance by the rubber plate 22 fixed to the lower surface of the exposure receiving member 2, the member 2 is still in the exposure receiving position.

Note that the resistance means for maintaining the dew receiving member 2 at the dew receiving position in this way regardless of the closing rotation of the door 9 is not limited to the rubber plate 22, but other means, for example, A spring or the like fitted to the shaft rod 91 and acting to always open the member 2 to the dew receiving position side may be adopted. When the contact resistance between the dew receiving member 3 and the member 2 is large, the dew-off member 3 may be used as a resistance unit.

Thus, when the free end notch 24 of the dew receiving member 2 reaches the lock pin 82 on the main body side, a resistance is received from the main body side, and the member 2 is subjected to the rubber plate cut line on the lower surface under the resistance. The pin 23 on the lower surface of the door 9 comes into contact with the end surface 21b of the long hole 21 of the member 2 by being pushed under the lower surface of the door 9 and stored against the resistance of 22A.

After that, when the door 9 is further closed and rotated, the body lock pin
82 engages the catch 25 and the door 9 is completely closed.

Thus, the notch 24 of the dew receiving member 2 is
Between the time you reach 82 and the time the door 9 is completely closed,
Since the dew-off member 3 on the lower surface of the door 9 slides along the upper surface of the dew-receiving member 2 toward the incubator main body 8, the dew accumulated on the member is pushed off from the member 2 by the dew-off member 3. And falls into the main body dew receiving portion 1.

According to the above-described embodiment, although the dew receiving member 2 that moves together with the door 9 is provided, the dew receiving member 2 is pushed and stored under the door 9 at the door closed position, so that the temperature and humidity are kept constant. There is no need to form a recess on the container body 8 side for accommodating the dew receiving member 2. When the door is opened, the member 2 surely projects to the front of the inner surface 92 of the door 9 and takes a dew receiving position, so that the dew flowing down the inner surface 92 of the door 9 is reliably received by the dew receiving member 2, and There is no danger of falling to the floor. Further, the dew accumulated on the member 2 is flushed out by the dew-off member 3 each time the door 9 is closed, and falls into the main body dew receiving portion 1 together with the door closed. There is little fear of falling.

Further, according to this embodiment, a drain pipe connecting the door 9 and the main body 1 is not required, and the dew receiving member 2 may be a plate-shaped member.

The present invention is not limited to the above embodiments, but can be implemented in various other modes.

In the embodiment, the catch 25 and the lock pin on the main body side are used as means for allowing the dew receiving member 2 to protrude in front of the inner surface of the door together with the opening of the door, and to be pushed in and housed under the door together with the closing of the door.
Although the combination of 82 and the combination of the long hole 21 of the exposure receiving member 2, the rubber plate 22 for closing the same, and the pin 23 which passes through the rubber plate and is screwed to the lower surface of the door are used,
For example, a spring 4 as shown in FIG. 5 may be employed.

The spring 4 is fitted on the pivot shaft 91 of the door 9 and its two free ends act to always open in directions opposite to each other. One free end 41 is a door. The other free end 42 abuts a spring stop 41 a provided on the dew receiving member 2. Therefore, when the door is opened, the dew receiving member 2 projects forward from the door inner surface 92 by the action of this spring,
When the door is closed, the member 2 receives the resistance from the thermostat main body 8 and is pushed into the lower surface of the door against the elasticity of the spring 4.

In addition, in the example shown in FIG.
It is provided diagonally so as to approach the door inner surface 92 as it approaches the side, so that the portion of the member 2 close to the shaft 91 having a small rotation range can be sufficiently exposed.

In the above embodiment, only one dew receiving member 2 is used. However, as shown in FIG. 6, this can be replaced with a plurality of dew receiving members 5 and 6.

The dew receiving members 5 and 6 correspond to the dew receiving member 2 in the above embodiment.
Similarly to the above, the door 9 is rotatably connected to both the door 9 and the thermo-hygrostat main body 8 by a pivot shaft 91 of the door 9. Also,
In this example, the lower surface of the door 9 is provided with a dew opening member 7 which is in contact with the upper surface of the upper dew receiving member 5, and the lower surface of the upper stage dew receiving member 5 is provided with a dew opening member which is in contact with the upper surface of the lower dew receiving member 6. 70 is provided.

An arc-shaped long hole 51 is provided in the upper dew receiving member 5, and an arc-shaped long hole 61 is provided in the lower dew receiving member 6, respectively. An attached rubber plate (not shown) is fixed, and pins passing through the cut line are screwed to the lower surface of the door 9 and the lower surface of the upper dew receiving member 5, respectively. Further, a notch 62 and a catch 25 similar to that described above are provided at the free end of the lower surface exposure receiving member 6, and a lock pin 83 is provided in the thermo-hygrostat body 8 in correspondence with the notch 62.

With this configuration, the two dew receiving members 5 and 6 project stepwise in front of the inner surface 92 of the door 9 when the door is opened, and take the dew receiving position. And the dew-off members 7 and 70 flow the dew on the dew-receiving members 5 and 6 into the main-body dew-receiving portion 1 accordingly.
