Abstract
The utility model discloses a novel thermostatic chamber, which comprises a chamber body and a chamber door. An electric heating element is arranged at the bottom of an inner cavity of the chamber body, and the electric heating element connected with a temperature control circuit system is controlled to be powered on or off by the temperature control circuit system. The heating element of the novel thermostatic chamber is arranged at the bottom of the chamber body, the novel thermostatic chamber consumes less than one kilowatt of electricity in 24-hour electrified work, can realize double temperature control, ensures safety and reliability by placing an overheating protecting device inside, and is simple in operation, convenient in use and high in temperature control precision.
Description
Technical field
The utility model relates to a kind of insulating box, belongs to the electric heating equipment technical field, refers in particular to a kind of novel constant-temperature case that improves structure.
Background technology
At current medical field, patient often because fluid temperature is low excessively, differs too big with the Human Physiology temperature in therapeutic process, and causes patient body pain or uncomfortable reaction occurs.At the problems referred to above, sometimes healthcare givers or patient can utilize hot-water bottle etc. that woven hose, transfusion position are heated.Though this method can reach certain heats, might also can reduce drug effect sometimes because of the local overheating scalded patient, it is cumbersome to operate simultaneously.The insulating box that is used at present other field on the market, can heat and keep uniform temperature, this class insulating box major part be wound in heater element around the casing or directly place in the case, though heating is than very fast, power consumption is big, and heat runs off easily, waste energy, and accuracy of temperature control is not high, occurs overheated phenomenon easily, is difficult to applying aspect the soup constant temperature.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of power consumption little, and heat is difficult for scattering and disappearing and the higher insulating box of accuracy of temperature control.
To achieve these goals, the utility model is realized by following technical scheme:
A kind of novel constant-temperature case comprises a casing and a chamber door, and described cabinets cavity bottom surface is provided with the electric heating heater element, and this electric heating heater element is connected with the temperature control circuit system by its control break-make.
Further, described electric heating heater element is a heating wire, is close to the cabinets cavity bottom surface.
Further, described temperature control circuit system comprises temperature controller and IC temperature control circuit, between temperature controller and the electric heating heater element by normally closed switch conducting or disconnection by the control of IC temperature control circuit.
Further, be provided with an envelope around the casing of around the described chamber door inboard and corresponding chamber door position.
Further, be provided with the magnetic door-inhale around the described chamber door.
Further, be filled with heat insulating material layer between the described casing interlayer.
The utility model heater element is located at bottom half, and whole day energising in 24 hours work power consumption deficiency once is built-in with overtemperature protection system, guarantees safe and reliable; Simple to operate, easy to use, the temperature-controlled precision height.
In order to understand the utility model more clearly, set forth embodiment of the present utility model below with reference to description of drawings.
Description of drawings
Fig. 1 is a fragmentary sectional elevation view of the present utility model.
Fig. 2 is a schematic internal view of the present utility model.
Embodiment
As shown in Figure 1, 2, the utility model comprises a casing 1 and a chamber door 2, and chamber door 2 casings 1 all around inboard and corresponding chamber door 2 positions are provided with an envelope 3 all around, also are provided with the magnetic door-inhale around the chamber door 2.Be filled with heat insulating material layer 10 between casing 1 interlayer; Casing 1 top is provided with mains switch and guidance panel.
Above-mentioned casing 1 inner chamber bottom surface is close to and is provided with heating wire 11, is connected with the temperature control circuit system and by its control break-make.Wherein, the temperature control circuit system comprises fuse, temperature controller and IC temperature control circuit, and fuse and temperature controller serial connection is controlled the conducting of heating wire 11 by the normally closed switch of being controlled by the IC temperature control circuit between sequential circuit and the heating wire 11 or closed.
The utility model is not limited to above-mentioned execution mode, if various changes of the present utility model or modification are not broken away from spirit and scope of the present utility model, if these are changed and modification belongs within claim of the present utility model and the equivalent technologies scope, then the utility model also is intended to comprise these changes and modification.
