Abstract
The utility model discloses a kind of temperature control device used in drinking water machines, including a control circuit and a cooling or heating device arranged outside the water storage barrel of the drinking water machines; the control circuit is electrically connected with the loops of the cooling or heating device; the control circuit mainly includes a SCM with computer procedures of temperature control; the control circuit is connected with the temperature sensor used in the detection of the water temperature in the water storage barrel; the temperature sensor is located the outside water storage barrel, isolated from the water storage barrel and arranged in the cooling or heating device. The temperature control device of the utility model used in drinking water machines can accurately detect the heating load condition of the cooling or heating device, so as to accurately control of the temperature of the drinking water in the water storage barrel; at the same time, the device also prevents the secondary pollution of the water, and makes the drinking water meet the health requirement of cleanness.
Description
Technical field
The utility model relates to a kind of water dispenser attemperating unit.
Background technology
At present, common water dispenser attemperating unit in the prior art, its temperature control principle as shown in Figure 1 and Figure 2, basic structure then generally includes control circuit and is located at water dispenser water storage barrel outer refrigeration or heater, control circuit and refrigeration or heater loop are electrically connected, be connected with a temperature sensor on the control circuit, temperature sensor is built in water storage barrel or is close to the outer surface of water storage barrel.As disclosed built-in temperature probe of Chinese patent ZL01230011.X and the cold courage of evaporimeter water dispenser, the thermostat probe of this equipment is arranged in the cold courage of water dispenser, the attemperating unit of this structure, built-in thermostat probe is often because of itself material character, easily physical change or chemical reaction taking place in water and causes the secondary pollution of water quality, do not meet the hygienic requirements of drinking water, the user is constituted certain health threat.In addition, temperature controller is close to the attemperating unit of water storage barrel outer surface, as shown in Figure 2, collided unexpectedly when temperature controller and peeled off outer surface in water storage barrel, cause temperature control inaccurate on the one hand, may damage temperature controller on the other hand, influence the operation of attemperating unit.So, the attemperating unit of water dispenser in the prior art, the temperature control effect of its hygienic requirements and reality is 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 water dispenser attemperating unit of water pollution once again.
Goal of the invention of the present utility model is achieved in that a kind of water dispenser attemperating unit, comprise control circuit and be located at water dispenser water storage barrel outer refrigeration or heater, control circuit and refrigeration or heater loop are electrically connected, be connected with the temperature sensor that is used to detect water temperature in the water storage barrel on the control circuit, it is characterized in that: described temperature sensor is located at outside the water storage barrel and with water storage barrel and is isolated.
Described temperature sensor is located in refrigeration or the heater.
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 with attemperating unit the water dispenser of prior art, temperature sensor is installed in the water storage barrel of water dispenser isolates outward and with water storage barrel, 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 thermic load situation of refrigeration or heater exactly, and accurately control the refrigeration or the duty of heater according to result of calculation, make it provide suitable heat supply or refrigerating capacity to drinking water, thereby reach the temperature of accurately controlling drinking water in the water storage barrel, simultaneously, because the water storage barrel of temperature sensor and water dispenser is isolated, effectively prevented the secondary pollution of water quality, made drinking water also reach the requirement of clean hygiene.
Description of drawings
Accompanying drawing 1 is the principle schematic of a kind of attemperating unit that water dispenser is used in the prior art.
Accompanying drawing 2 is the principle schematic of the another kind of attemperating unit that water dispenser is used in the prior art.
