Description

Technical Field

[0001] The utility model relates to the technical field of constant temperature and humidity chambers, and particularly relates to a door structure and a constant temperature and humidity chamber. Background Art

[0002] A constant temperature and humidity chamber is a test device that can maintain a set temperature and humidity within a certain range and is used to test the effects of different environmental conditions on products or materials. For the convenience of observation during the test process of the constant temperature and humidity chamber, a glass for observation is provided on the door of the constant temperature and humidity chamber.

[0003] In the case of certain test environmental conditions, water droplets will condense on the inner wall of the existing constant temperature and humidity chamber. Under the action of gravity and the vibration generated during the operation of the device, the condensed water droplets will flow downward. There is a situation where the flowing water droplets flow onto the door glass. At this time, water droplets will remain on the door glass or traces of water droplet flow will be left, which will cause the transparency of the door glass to decrease and affect the test personnel's observation of the test results inside the chamber. Summary of the Utility Model

[0004] The main purpose of the utility model is to propose a door structure and a constant temperature and humidity chamber, aiming to solve the problem of the decreased clarity of the door glass during the test process of the constant temperature and humidity chamber.

[0005] To achieve the above object, the door structure proposed by the utility model is used for a constant temperature and humidity chamber, and the door structure includes:

[0006] A door body having a front surface, a back surface, and an observation port;

[0007] A glass installed in the observation port and disposed close to the back surface of the door body; and

[0008] A flow disturbing portion installed on the back surface of the door body and disposed above the glass to change the trajectory of the water droplets flowing towards the glass so that the water droplets flow outside the glass.

[0009] In an embodiment, the flow disturbing portion has a first end close to the glass and a second end far from the glass. The first end abuts against the back surface of the door body, and the second end is far from the back surface of the door body.

[0010] In an embodiment, an installation cavity is formed on the back surface of the door body, and the glass is installed in the installation cavity;

[0011] The door structure further includes a limiting member fixedly provided on the back surface of the door body to limit the glass in the installation cavity.

[0012] In an embodiment, the limiting member is fixedly provided on the back surface of the door body by means of screw locking.

[0013] In one embodiment, the interior of the door body is a hollow structure. The hatch structure includes a mounting frame, which is fixedly arranged inside the door body, and an installation cavity is formed in the mounting frame.

[0014] In one embodiment, the mounting frame is fixedly arranged on the door body by means of screw attachment. The area of the mounting frame close to the limiting member shares the screw attachment to the door body with the limiting member.

[0015] In one embodiment, the limiting member is configured as a plate-like structure, and an observation hole is formed in the middle of the limiting member.

[0016] In one embodiment, the limiting member has an outwardly turned bending portion, which is arranged above the glass, and the bending portion is configured as a flow disturbing portion.

[0017] The present utility model further provides a constant temperature and humidity chamber, which includes a box body and a hatch structure. The hatch structure is the hatch structure as described in any one of the above, and the hatch structure is installed on the box body.

[0018] In one embodiment, the constant temperature and humidity chamber further includes a water storage tray installed on the box body. The water storage tray is arranged below the hatch structure and has an opening facing the hatch structure.

[0019] The technical solution of the present utility model uses a flow disturbing portion to change the trajectory of the water droplets flowing towards the glass. At this time, the water droplets flow downward under the action of gravity and the vibration generated by the constant temperature and humidity chamber. When some water droplets flow towards the glass, since the flow disturbing portion is arranged above the glass and can change the trajectory of the water droplets flowing towards the glass, at this time, some water droplets do not flow towards the glass under the action of the flow disturbing portion but flow to other places, so as to avoid the residue of water droplets on the glass and the traces of water droplets remaining on the glass, thereby avoiding the decrease in the clarity of the glass, and further being able to solve the technical problems existing in the prior art.

[0039] A thermostatic and humidistatic chamber is a test device that can maintain a set temperature and humidity within a certain range and is used to test the effects of different environmental conditions on products or materials. For the convenience of observation during the test process, a glass for observation is provided on the door of the thermostatic and humidistatic chamber.

[0040] In the case of certain test environmental conditions, water droplets will condense on the inner wall of the existing thermostatic and humidistatic chamber. Under the action of gravity and the vibration generated during the operation of the device, the condensed water droplets will flow downward, and there is a situation where the flowing water droplets flow onto the door glass. At this time, water droplets will remain on the door glass or traces of water droplet flow will be left, which will cause the transparency of the door glass to decrease and affect the test personnel's observation of the test results inside the chamber.

[0041] The present utility model proposes a door structure for a thermostatic and humidistatic chamber.

[0042] Please refer to Figure 1 、 Figure 3 、 Figure 5 In an embodiment of the present utility model, the door structure includes:

[0043] A door body 100, having a front surface, a back surface, and an observation port 120. The door body 100 is hinged to the thermostatic and humidistatic chamber through a hinge. The back surface of the door body 100 is the side close to the thermostatic and humidistatic chamber, and the front surface of the door body 100 is the side far from the thermostatic and humidistatic chamber.

[0044] The glass 200 is installed at the observation port 120 and is disposed near the back surface of the door body 600. Further, in the hatch structure of the present application, the glass 200 is configured as a double-layer or multi-layer glass 200 structure. Further, when a double-layer or multi-layer glass 200 is adopted, dry air or an inert gas (argon) is filled in the middle of the glass 200, which can effectively reduce the condensation of water droplets on the glass 200 caused by the temperature difference between the inside and the outside.

[0045] The spoiler 300 is installed on the back surface of the door body 100 and is disposed above the glass 200 for changing the trajectory of the water droplets flowing towards the glass 200 so that the water droplets flow outside the glass 200. Specifically, when the constant temperature and humidity chamber is in use, water droplets condense on the inner wall of the box body 600 under specific environmental conditions. At this time, the water droplets flow downward under the action of gravity and the vibration generated by the constant temperature and humidity chamber. When some water droplets flow towards the glass 200, since the spoiler 300 is disposed above the glass 200 and can change the trajectory of the water droplets flowing towards the glass 200, at this time, some water droplets do not flow towards the glass 200 under the action of the spoiler 300 but flow to other places, thereby avoiding the residue of water droplets on the glass 200 and the traces of water droplets remaining on the glass 200, thus avoiding the decrease in the clarity of the glass 200 and further solving the technical problems existing in the prior art.

[0046] In an embodiment, the spoiler 300 may adopt the following structure. The spoiler 300 has a first end 310 close to the glass 200 and a second end 320 far from the glass 200. The first end 310 abuts against the back surface of the door body 100, and the second end 320 is far from the back surface of the door body 100. At this time, during the downward flow of the water droplets, since the spoiler 300 is disposed above the glass 200, the water droplets first contact the spoiler 300. Since the second end 320 of the spoiler 300 far from the glass 200 is disposed far from the back surface of the door body 100, when the water droplets flow downward along the back surface of the door body 100, they will flow into the space between the spoiler 300 and the back surface of the door body 100. At this time, the first end 310 of the spoiler 300 abuts against the back surface of the door body 100. Under the blocking action of the first end 310, the water droplets cannot continue to flow downward, but will move along the extending direction of the spoiler 300 under the action of vibration, thereby changing the trajectory of the water droplets and avoiding the water droplets flowing towards the glass 200 and affecting the clarity of the glass 200.

[0047] However, this design is not limited to this. In other embodiments, the spoiler 300 can also adopt other structures. The second end 320 of the spoiler 300 abuts against the back surface of the door body 100, and the first end 310 of the spoiler 300 is arranged away from the back surface of the door body 100. At this time, when the water droplets flow towards the glass 200, the water droplets will continue to move downward and flow from the second end 320 of the spoiler 300 to the first end 310. Since the first end 310 is arranged away from the back surface of the door body 100, when the water droplets flow downward at this time, they also move away from the glass 200, reducing the probability of the water droplets flowing towards the glass 200.

[0048] In one embodiment, referring to Figure 4 , an installation cavity 110 is formed on the back surface of the door body 100, and the glass 200 is installed in the installation cavity 110. This is to facilitate the installation of the glass 200 on the door body 100 and enable the glass 200 to be closer to the constant temperature and humidity chamber, reducing the space between the inner top surface of the observation port 120 and the constant temperature and humidity chamber, avoiding the condensation of water droplets in this space, and at the same time facilitating the installation of the spoiler 300; the hatch structure further includes a restricting member 400, and the restricting member 400 is fixedly arranged on the back surface of the door body 100 to restrict the glass 200 in the installation cavity 110. Specifically, when installing the glass 200, after installing the glass 200 in the installation cavity 110, then fixedly arrange the restricting member 400 on the back surface of the door body 100. When the restricting member 400 is fixedly arranged on the back surface of the door body 100, a part of the structure of the restricting member 400 abuts against the glass 200 to restrict the glass 200 in the installation cavity 110.

[0049] In one embodiment, referring to Figure 3 , the restricting member 400 is fixedly arranged on the back surface of the door body 100 by means of screw locking. This is to facilitate the installation and disassembly of the restricting member 400. At the same time, by means of screw locking, different screws can be selected, so that the connection between the restricting member 400 and the door body 100 has certain seismic resistance, avoiding the existence of a gap between the restricting member 400 and the back surface of the door body 100 during long-term use of the equipment, and avoiding the situation where the glass 200 cannot be stably installed in the installation cavity 110.

[0050] In one embodiment, the interior of the door body 100 is a hollow structure. Using a hollow-structured door body 100 can reduce the weight of the door body 100 and facilitate the opening and closing of the hatch structure; at the same time, in order to facilitate the installation of the glass 200 in the door body 100, further, the hatch structure includes an installation frame 500, the installation frame 500 is fixedly arranged inside the door body 100, and the installation cavity 110 is formed in the installation frame 500. At this time, the glass 200 can be installed in the installation frame 500, and then installed on the door body 100.

[0051] In one embodiment, referring toFigure 3 , Figure 4 , the mounting bracket 500 is fixedly provided on the door body 100 by means of screw attachment. In this way, the installation and disassembly of the mounting bracket 500 can be facilitated, and at the same time, the production process difficulty of the hatch structure can be reduced. Further, the area of the mounting bracket 500 close to the limiting member 400 and the limiting member 400 share screw attachment to the door body 100. In this way, the connection between the mounting bracket 500 and the limiting member 400 can be made more stable, so that the glass 200 cup arranged in the installation cavity 110 can be more stably restricted by the restricting frame.

[0052] In one embodiment, referring to Figure 6 , the limiting member 400 is configured as a plate-like structure, and an observation hole 420 is provided in the middle of the limiting member 400. The external contour shape of the plate-like limiting member 400 can be set according to the shape of the glass 200. Among them, the shape of the glass 200 in this application is approximately rectangular (see Figure 6 ), and at this time, the external contour of the plate-like limiting member 400 is also approximately rectangular. In other embodiments, when the shape of the glass 200 is circular (not shown), the external contour of the plate-like limiting member 400 can also be circular.

[0053] In one embodiment, referring to Figure 6 , the limiting member 400 has an outwardly turned bending portion 410, and the bending portion 410 is arranged above the glass 200. The bending portion 410 is configured as a spoiler 300. Specifically, the spoiler 300 and the limiting member 400 are integrally formed. In this way, when the limiting member 400 is installed, the spoiler 300 can be installed on the door body 100 together, reducing the assembly process and cost. At the same time, the integral formation of the spoiler 300 and the limiting member 400 can make the connection between the two seamless, and can achieve a better water droplet diversion effect.

[0054] The present utility model also proposes a constant temperature and humidity box, referring to Figure 1 , Figure 2 , the constant temperature and humidity box includes a box body 600 and a hatch structure. The specific structure of the hatch structure refers to the above embodiments. Since this constant temperature and humidity box adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one. Among them, the hatch structure is installed on the box body 600. Specifically, the door body 100 in the hatch structure is connected to the box body 600 by a hinge.

[0055] In one embodiment, referring to Figure 2, the constant temperature and humidity chamber further includes a water storage tray 700 installed on the box body 600. The water storage tray 700 is arranged below the hatch structure and has an opening facing the hatch structure. Further, under the action of the water storage tray, water droplets flowing downward on the door body 100 can be collected.

[0056] The above is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention.
