Description

The climatic chamber of a kind of improvement

Technical field

The present invention relates to the experiment utility appliance of the physical chemical laboratory, relate more specifically to the climatic chamber of a kind of improvement.

Background technology

Climatic chamber is a kind of conventional laboratory utility appliance, and function is for providing a temperature, moisture constant and controlled closed environment. Usually may be used for depositing the experiment sample that some need control temperature and humidity, when the stability of drug products such as underway state States Pharmacopoeia specifications is tested. Climatic chamber can experimentally need the temperature and the humidity that regulate box house, to reach the requirement of experiment condition.

In order to ensure accuracy and the consistence of experiment condition, usual climatic chamber box house should have balanced temperature and humidity. Envrionment test device temperature, humidity calibration scope have been carried out requirement by country of People's Republic of China (PRC) metering technology normalized JJF1101-2003. Therefore climatic chamber ensures that the harmony of temperature and humidity in casing is the regulation of industry, is also the prerequisite reaching its purposes, is particularly carrying out in stability of drug products experiment exam experimentation or is storing in medicine process.

At present, market has multiple climatic chamber, and the binder such as Germany stablizes case. The horizontal rack type shelf that existing climatic chamber generally comprises casing (containing heating and cooling device, adding wet device and fan) and is located in casing, being provided with the accommodating space with opening in this casing, this accommodating space can keep inner constant temperature, constant humidity. Surround in the two lateral walls of casing in this accommodating space, it is provided with the projection that a series of correspondence is arranged, for supporting horizontal shelf, such as Fig. 1. Such climatic chamber can regulate and control constant temp and humidity, it is also possible to obtain temperature balanced in casing and humidity.

Chinese patent literature CN102198408A, discloses a kind of climatic chamber, and described climatic chamber comprises casing and rack, is provided with the accommodating space with opening in this casing, and this rack is located in this accommodating space. This climatic chamber also comprises the lifters of this rack of support, drives the driving assembly of this lifters and control the controller of this driving assembly, and this this lifters of driving Component driver moves the height regulating rack. The height of the rack of described climatic chamber is conveniently adjusted, so that measuring the temperature in different heights casing and humidity.

Chinese patent literature CN202366717U, discloses a kind of bioconversion medium thermostat container device, described casing, by body skin, thermal insulation layer, housing, inner chamber body, put frame, passage of heat, dividing plate, warm air import hole, electric heating device and universal land wheel and form. The thermostat container device of the patent offer that described practicality is novel has the roughly equilibrium keeping temperature in thermostat container inner chamber, reduces the advantage of the temperature difference that electrically heated heats up in thermostat container inner chamber.

In above climatic chamber, all there is shelf in case less (being generally 2-4 layer), the article that can deposit are less, the problem that space availability is lower; And owing to lacking longitudinal subdivision, the sample of stacking placement can hinder air-flow in case unobstructed, affects humiture homogeneity; Exist simultaneously sample cannot Classification Management and take inconvenience problem,

In existing climatic chamber, it does not have solve the climatic chamber of the above technical problem existed. In order to overcome the shortcoming of above existence, the present invention provides a kind of structure simple, easy to operate, and overcomes the climatic chamber of the improvement of above technical problem.

Summary of the invention

Invention general introduction

The climatic chamber of improvement provided by the invention, according to the unimpeded of convection of air and the needs depositing article, is provided with the movable grid framework that can take out in casing, and described framework is made up of multiple small frame. Different small frames configures the drawer mated mutually. In order to ensure the harmony of temperature and humidity in casing, the structure of framework is designed, and be provided with on drawer and can make temperature and the not affected ventilating pit of humidity harmony, wherein ventilating pit is the aperture of constant dimension of being evenly distributed, and is convenient to air-flow unobstructed.

It is big that the climatic chamber of improvement provided by the invention has space availability, and in casing, temperature and humidity are balanced, the easy to operate and simple feature of structure.

Detailed Description Of The Invention

The present invention provides the climatic chamber of a kind of improvement, it movable grid framework comprising fixed temperature and humidity box body and can taking out, wherein said grid framework fixing can the small frame of support activities drawer be made up of multiple, each described small frame has the moveable drawer that can take out mated mutually, moveable drawer has the pore that air-flow can be made unimpeded.

Wherein said movable grid framework does not contact with climatic chamber cabinet wall; Preferably the surface of grid framework has the distance of 5cm with corresponding cabinet wall; More preferably each surface of grid framework, except towards, except cabinet door direction, having more than 3 outwardly projecting, described projecting 5cm, to be more prone to ensure the distance of grid framework and cabinet wall. By ensureing the distance of grid framework and cabinet wall, it is possible to make the air-flow in casing not be obstructed, be conducive to box interior temperature and humidity balanced.

Wherein said front and rear wall, left and right wall and the bottom that the pore that air-flow is unimpeded can be made to be evenly distributed on moveable drawer, has constant size, and hole diameter and spacing are 1cm, and circular hole arrangement mode is for being interspersed. When other conditions are constant, the size in drawer aperture and position distribution are the key factors directly affecting humiture homogeneity in case.

Further, described moveable drawer can also have multiple partition board, moveable drawer is separated into multiple sub-box, is more conducive to taxonomy of goods, and wherein said dividing plate also has the pore of the constant dimension that is evenly distributed; Preferably there are 2��10 dividing plates.

In order to play the effect of fixing moveable drawer, can also have, in the left and right side of each fixing small frame and bottom, the guardrail playing fixing moveable drawer, to prevent in use moveable drawer dislocation. Further, moveable drawer can be more smaller than the small frame mated, the left and right sidewall of moveable drawer and top and face distance 5cm in the small frame mated mutually.

Prepared by the climatic chamber of a kind of improvement of the present invention, wherein said grid framework and moveable drawer stainless steel wherein.

The climatic chamber of a kind of improvement of the present invention, wherein can also arrange dragging device at the antetheca of each moveable drawer; Further label insert slot is set at moveable drawer antetheca, different labels can be changed as required flexibly. Therefore have easy to operate, and the feature of convenient management.
