Abstract
The utility model discloses an indirect temperature sensing device, which comprises a control circuit and a heating or cooling device, wherein, the heating or cooling device is arranged at the outside of the controlled object, the control circuit is connected with the cooling or heating loop of the devices; the control circuit has a computer storing the temperature controlling program and is connected with temperature sensors to detect the object temperature. The temperature sensor is arranged at the outside of the object and isolated from the object, which is positioned in the cooling or heating device. The utility model can accurately detect the load of the cooling or heating device to achieve precise controlling over the object temperature, at the same time, the device also can effectively prevent the object from secondary polluting to satisfy the clean and sanitation requirements.
Description
Technical field
The utility model relates to a kind of indirect sensing attemperating unit.
Background technology
At present, common attemperating unit in the prior art, its basic structure generally includes control circuit and is located at temperature control object outer refrigeration or heating arrangement, control circuit and refrigeration or heating arrangement loop are electrically connected, be connected with a temperature sensor on the control circuit, temperature sensor is built in the temperature control object or is close to the outside surface of temperature control object.But, the attemperating unit of these two kinds of structures, in the use of reality, also there is weak point respectively: one, temperature sensor is built in the attemperating unit of temperature control object, its temperature control sensor often because of itself material character or be subjected to the influence of temperature control object, physical change or chemical reaction take place in the temperature control object easily, and cause secondary pollution, particularly on food, potable water and fine chemistry industry material, the secondary pollution problem that temperature controller caused is even more serious, and the user is constituted certain health threat; Its two, temperature controller is close to the attemperating unit of water storage barrel outside surface, when temperature controller is subjected to unexpected collision and peels off in the outside surface of temperature control object, thermometric is inaccurate thereupon on the one hand, temperature control also just can not realize, may damage temperature controller on the other hand, influences the operation of attemperating unit.So, attemperating unit of the prior art, the temperature control effect of its hygienic requirements and reality is all relatively poor.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of temperature control accurately, effectively to prevent the indirect sensing attemperating unit of temperature control object secondary pollution.
Goal of the invention of the present utility model is achieved in that a kind of indirect sensing attemperating unit, comprise control circuit and be located at temperature control object outer refrigeration or heating arrangement, control circuit and refrigeration or heating arrangement loop are electrically connected, be connected with the temperature sensor that is used to detect the temperature control object temperature on the control circuit, it is characterized in that:
Described temperature sensor is located at outside the temperature control object and with the temperature control object and is isolated.
Described temperature sensor is located in refrigeration or the heating arrangement.
Described control circuit comprises the single-chip microcomputer that has the computer temperature-control program.
Described temperature sensor is a semiconductor temperature sensor.
The utility model improves the attemperating unit of prior art, temperature sensor is installed in outside the temperature control object and with the temperature control object isolates, and its control circuit mainly is made up of the single-chip microcomputer that has the computer temperature-control program, pass through computer software technology, can detect the thermal load situation of refrigeration or heating arrangement exactly, and accurately control the refrigeration or the duty of heating arrangement according to result of calculation, make it provide suitable heat supply or refrigerating capacity, thereby reach the temperature of accurately controlling the temperature control object to the temperature control object.Simultaneously, apparatus structure is simple, and temperature sensor and the isolation of temperature control object, has effectively prevented the secondary pollution problem of temperature control object, has guaranteed the clean hygiene requirement of temperature control object.
Description of drawings
Accompanying drawing 1 is the principle schematic of the utility model most preferred embodiment.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
According to shown in Figure 1, indirect sensing attemperating unit of the present utility model, comprise control circuit 1 and refrigeration or the heating arrangement 3 be located at outside the temperature control object 2, control circuit 1 and refrigeration or heating arrangement 3 loops are electrically connected, refrigeration or heating arrangement 3 constitute for evaporator with heat pump or by other heating arrangement and refrigerating plant, control circuit 1 is then integrated to be arranged on the circuit board, and it mainly is made up of the single-chip microcomputer that has the computer temperature-control program, on control circuit 1, also be connected with the temperature sensor 4 that is used to detect temperature control object 2 temperature, temperature sensor 4 is semiconductor temperature sensor and is located in refrigeration or the heating arrangement 3, simultaneously, for preventing the secondary pollution problem of 4 pairs of temperature control objects 2 of temperature sensor, this temperature sensor 4 is located at outside the temperature control object 2 and with temperature control object 2 and is isolated.Indirect sensing attemperating unit of the present utility model, be not subjected to the weight of temperature control object 2, volume and the influence that reaches form, temperature control object 2 can be solid-state, liquid state or gaseous material, for example be food, potable water, fine chemistry industry material and gaseous matter all can reach temperature control effect described in the utility model, during this time, by temperature sensor 4 coupled computer software engineerings, can detect the thermal load situation of refrigeration or heating arrangement 3 exactly, refrigeration or heating arrangement 3 accurately provide suitable heat supply or refrigerating capacity to temperature control object 2 according to result of calculation, thereby reach accurate temperature controlling to temperature control object 2, simultaneously, apparatus structure is simple, and temperature sensor 4 and 2 isolation of temperature control object, has effectively prevented the secondary pollution problem of temperature control object 2, guarantee the hygienic requirements of temperature control object 2, improved the usability of temperature control product.
