Description

Environment temperature and humidity calibrating device and environment simulation room thereof
Technical Field
The utility model relates to the technical field of temperature and humidity detection, in particular to an indoor environment temperature and humidity verification device; the utility model also relates to an environment simulation chamber utilizing the environment temperature and humidity calibrating device.
Background
The use of environmental simulation chambers is often required in the manufacture and inspection of wood products such as wood floors, wood furniture boards, and the like. For example, in manufacturing, wood products are placed in an environmental simulation chamber for a set period of time to achieve a desired level of moisture content. In another example, in the detection, the wood product is placed in an environmental simulation chamber with constant temperature and humidity or regular change for a set period of time to know the rule of the dimensional change or judge whether the dimensional change amount is acceptable.
An environment simulation room in the prior art, such as a balancing room described in the patent publication No. CN201058450Y in the Chinese patent database and named as a panel drying treatment room, detects the indoor temperature and humidity through a probe connected with a control host, and controls an air inlet pipe and a moisture absorption pipe through the control host to adjust or change the temperature and humidity in the balancing room so as to maintain or change the temperature and humidity in the balancing room. However, this method has poor sensitivity in detecting temperature and humidity and low adjustment and feedback efficiency.
In the prior art, as disclosed in the patent application with publication number CN114353865a, the utility model is named as a temperature and humidity detection circuit and a temperature and humidity detection method, which has relatively high detection precision, high adjustment and feedback efficiency and small space occupation.
However, unlike environmental simulation chambers storing electronic products, in environmental simulation chambers for moisture content adjustment or dimensional stability detection of wood products, wood products can exchange temperature, particularly humidity, with temperature and humidity media in the chamber to a large extent. In other words, when the moisture content of the wood product is reduced by the temperature and humidity medium, the moisture in the wood product volatilizes indoors so as to influence the temperature and humidity of the medium; when the moisture content of the wood product is increased, the wood product absorbs the moisture of the medium, thereby affecting the temperature and humidity of the medium. At the same time, the temperature and humidity of the medium do not change synchronously. In general, the change in temperature and humidity of a medium caused by moisture in a wood product is that the change in temperature lags behind the change in humidity. On the other hand, the initial water content of the wood products placed at different positions in the same environment is different, so that the interactive influence of the medium and the temperature and humidity of the wood products in the same environment is different. This results in (1) high precision temperature and humidity sensors often fluctuate significantly and relatively severely so that it is difficult for people to read effective temperature and humidity data, and (2) mediums in various local areas (actually having different temperatures and humidities) have not been sufficiently mixed to flow through the temperature and humidity detection probe, thereby further confusing the readings of the sensitive probe.
In summary, there is a lack of a verification device in the prior art that can relatively accurately reflect the temperature and humidity in an environmental simulation chamber.

Description of the embodiments
In order to make the technical solution of the present utility model better understood by those skilled in the art, the technical solution of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, shall fall within the scope of the utility model.
Example 1
Referring to fig. 1, the present embodiment provides an environmental temperature and humidity calibration device 100, which includes a housing, a temperature sensing unit 121 and a humidity sensing unit 122 mounted in the housing. In particular, the housing includes a tubular cavity 111 having a rectangular interface shape, and a pair of diaphragm plates 112 are provided on an inner wall of the tubular cavity 111, and the diaphragm plates 112 partially block a medium passage of the tubular cavity 111. Wherein the medium is dry air having a temperature that flows through the housing to form a medium flow. The temperature sensing unit 121 and the humidity sensing unit 122 are installed in a space defined by an inner wall of one side of the tubular cavity and the pair of diaphragm plates 112. In other words, as shown in fig. 2, due to the partial obstruction of the diaphragm 112, the air flows detouring to the space defined by the inner wall of one side of the tubular cavity and the pair of diaphragms 112, and forms a relatively stable air flow to be detected for the temperature sensing unit 121 and the humidity sensing unit 122 to obtain readable and relatively stable temperature and humidity data.
The temperature sensing unit 121 and the humidity sensing unit 122 are any available sensor products in the prior art, and they are detachably mounted on the inner wall of the tubular cavity. One possible assembly method is that the plugging strip 113 is welded or screwed on the inner wall of the tubular cavity, the clamping grooves 123 matched with the plugging strip 113 are arranged on the outer vertical surfaces of the protective shells of the temperature sensing unit 121 and the humidity sensing unit 122, and the temperature sensing unit 121 or the humidity sensing unit 122 is assembled by inserting the clamping grooves 123 into the plugging strip 113.
Example 2
Referring to fig. 3, the present embodiment provides an environmental temperature and humidity calibration device 100, which is different from embodiment 1 in that a temperature sensing unit 121 and a humidity sensing unit 122 are installed on an inner wall of one side of a tubular cavity 111 and located between a pair of diaphragms 112, but the diaphragms 112 cannot, and in this embodiment, the temperature sensing unit 121 and the humidity sensing unit 122 do not need to be completely shielded.
At the same time, the tubular cavity 111 has end caps 114 at both ends, and a pair of end caps 114 can be simultaneously opened to allow the medium to circulate in the tubular cavity 111 or simultaneously closed to allow the medium to stay in the tubular cavity 111. Specifically, the opening and closing between the end cover 114 and the end of the tubular cavity 111 are controlled by an electromagnetic relay connected to a control system. The control system may be of the prior art, such as a PLC controller. When both are in the open state, the end cap 114 is separated from the end of the tubular cavity 111 and forms an opening, but remains connected to the end of the tubular cavity 111 by the elastic member 115. The elastic member 115 is a spring, one end of which is fixedly (welded or screwed) connected to the diaphragm 112, and the other end of which is fixedly (welded or screwed) connected to the end cap 114. The elastic member 115 connected to the upper end cap 114 separates the end cap 114 from the end of the tubular cavity 111 by its compression property, and the elastic member 115 connected to the lower end cap 114 is connected to the end cap 114 by its tension property to prevent its detachment.
In particular, when the end cap 114 is in the open state, a distance of 1-3 cm (e.g., 2 cm) is provided between the end cap 114 and the end of the tubular cavity 111 to ensure that the medium flows into and out of the tubular cavity 111.
Example 3
Referring to fig. 4, the present embodiment provides an environmental temperature and humidity calibration apparatus 100, which is different from embodiment 2 in that the tubular cavity 111 is cylindrical. However, it will be understood by those skilled in the art that the shape of the tubular cavity 111 is not limited to either rectangular or circular, and that a pipe having a profiled cross-sectional shape may be selected as desired.
Example 4
Referring to fig. 5, the present embodiment provides an environment simulation chamber using the environment temperature and humidity calibration apparatus 100, which includes a simulation chamber body 200, a temperature and humidity control system 300 and a control system located on top of the simulation chamber body 200, where the simulation chamber body 200 is an indoor environment with a certain tightness in the prior art. The temperature and humidity control system 300 is a prior art, such as an air conditioner, as well as a compressor and humidifier combination, and is electrically connected to the control system in conjunction with the environmental temperature and humidity verification device 100. The environmental temperature and humidity calibration device 100 is disposed on two opposite inner walls of the simulation chamber body 200, and the temperature and humidity control system 300 is disposed on the top of the simulation chamber body 200 and is capable of exchanging medium with the inner environment of the simulation chamber body 200.
The air guiding unit 400 is arranged below the temperature and humidity control system 300, and the air guiding unit 400 can change the flow direction of the medium between the environment temperature and humidity verification devices 100 at two sides.
Specifically, referring to fig. 6 and 7, the air guide unit 400 includes a fixing frame 410, and the fixing frame 410 is screw-fixedly installed at the top of the simulation chamber body 200. The plurality of rotating shafts 420 are rotatably installed through the fixing frame 410, and the wind guide blades 430 are welded or integrally formed on the rotating shafts 420. The end of the rotation shaft 420 is connected with a sleeve 441 through a flat key, a plectrum 442 is integrally formed at the top of the sleeve 441, a perforation is formed on the plectrum 442, a connecting rod 443 passes through the perforation of the plectrum 442 on a plurality of rotation shafts 420 and is connected through a bolt 444, one end of the connecting rod 443 is fixed with a limiting plate 445, the other end is connected with the movable end of a linear cylinder 446, and the linear cylinder 446 is mounted on the fixed frame 410 through a cylinder seat 447 in a threaded manner. Therefore, the expansion and contraction of the linear air cylinder 446 can drive the air guiding blade 430 to change the deflection direction, and finally change the air outlet direction of the temperature and humidity control system 300 and the air flow direction in the environment simulation room.
For example, in the drying process, when the temperature and humidity detected by the environmental temperature and humidity detecting device 100 located at one side of the simulation chamber main body 200 is higher than that at the other side, the direction of the air guiding unit 400 is changed to enable the medium air flow to flow from the high side to the low side, so that the problem of uneven temperature and humidity in the simulation chamber main body 200 caused by temperature and humidity exchange between the wood product and the medium is relieved, and the purpose of balancing the temperature and humidity of the simulation chamber main body 200 is achieved.
