Disposal scheme of refrigerator temperature alarm

Refrigerator is an electrical product that needs long-term normal operation. Its abnormal operation often leads to the gradual increase of the temperature in the box. If the time is too long and the temperature exceeds a certain range, the stored items will deteriorate, and the damage caused by ordinary household ice boxes is still very small. For the refrigerator used to store blood, tissue samples and experimental reagents, its abnormal operation will bring huge or even irreparable losses. When the refrigerator works abnormally, it is necessary to repair or transfer the stored items to other refrigerators in time to avoid deterioration of the stored items. So it is very important to find the abnormality of refrigerator as soon as possible. But at present, there is no refrigerator with this function in the market, and related patents have been applied, such as network refrigerator (0248729. 2) The above functions can be achieved, but the popularity of Internet in China is not wide enough, and the manufacturing and operating costs of network refrigerators are high. Therefore, it is necessary to design a stable, reliable and low-cost temperature alarm device that can report the abnormal temperature of the refrigerator in time.

In view of the above problems, the purpose of the utility model is to provide an alarm device, which can inform the user in time when the temperature in the refrigerator box is abnormal. Because the fixed telephone and mobile telephone have been widely used in China, the method of telephone report is adopted. The embodiment of the utility model is based on the existing refrigerator and fixed telephone. The refrigerator temperature telephone alarm device consists of a central processing unit and a program solidified in the central processing unit, a dialing, digital and voice unit, a temperature measuring unit (available in existing refrigerators), a fixed telephone, a control panel and a standby power supply. The temperature measuring unit measures the temperature of each compartment in the refrigerator body in real time, and the central processing unit can collect temperature information from the temperature measuring unit and process the data. When the temperature is higher than the preset alarm temperature, the dialing, numbering and voice unit dials the reported user number through the connected fixed telephone until the user's telephone is connected, and notifies the user of the abnormal situation through the pre-stored voice. When the refrigerator is powered off, the central processing unit, dialing, numbering and voice units receive current supply from the standby power supply. The control panel is installed on the refrigerator door and used to set the alarm temperature, dialing and telephone number and voice of the central processor. The fixed telephone is installed near the refrigerator by the user and connected with dialing, number and voice units through transmission lines. Central processing unit, dialing, digital and voice units, temperature measuring unit and standby power supply are installed in the refrigerator. The invention has the beneficial effects that the abnormal temperature in the refrigerator can be reported to users in time, reliably, easily operated and at low cost, so as to avoid losses.

The utility model will be further explained by the attached drawings and examples. Fig. 1 is a schematic diagram of the utility model.

Embodiment 1 The utility model includes the temperature measuring unit 2 that the refrigerator now has, which measures the temperature in the refrigerator box in real time and transmits it to the central processor 1, and the central processor and the program solidified in it constitute the central processor 1. The temperature information from the temperature measuring unit 2 can be collected in real time and compared with the alarm temperature preset by the user through the control panel 7 (for example, when the freezing room temperature is higher than 0.5℃, an alarm is set). When the temperature from the temperature measuring unit 2 is found to be higher than the alarm temperature (for example,14.degree. C.), the dialing, numbering and voice unit 3 dials a report phone (which may be a fixed phone) through the fixed phone 4 with the number set by the user through the control panel 7. Users can set multiple alarm temperatures. When the temperature in the refrigerator is abnormal, they can report to the user at each alarm temperature. If the information from the temperature measuring unit 2 disappears, it will be used as a user to report the temperature abnormality. Users can set up multiple report phones, and when the temperature in the refrigerator is abnormal, they can dial all the set report phones one by one or at the same time. If the refrigerator power supply is interrupted, the standby power supply 5 is enabled to provide current for the refrigerator temperature telephone alarm device.

A refrigerator temperature telephone alarm device is characterized by consisting of a central processing unit, a dialing and numbering and voice unit, a temperature measuring unit, a fixed telephone, a control panel and a standby power supply. The temperature measuring unit measures the temperature in the refrigerator body in real time, and the central processing unit collects temperature information from the temperature measuring unit and processes the data. When the temperature is higher than the alarm temperature preset by the user, the dialing, number and voice unit dials the report telephone number set by the user through the connected fixed telephone until the user is connected, and the user is informed of the abnormal situation through the pre-stored voice. When the refrigerator is powered off, the central processing unit, the dialing, number and voice unit receive the current supply of the standby power supply.
