It is denoted as T2；
Step 2 acquires indoor temperature between defrosting heater surface temperature and standalone feature after the t time again,
Successively record；
Step 3, collected defrosting heater temperature data, is divided into △ t between the setting reduced time, by △ t before and after the processing
Temperature value before and after time compares, operation, allows to change when the front and back temperature gap of defrosting heater is greater than heater
Step 4 is carried out when temperature T1, otherwise return step two；
Step 4, before and after the processing collected function compartment temperature data carry out the temperature value before and after the △ t time pair
Than, operation, when the front and back temperature gap of function compartment, which is less than compartment, allows transformation temperature T2, step 5 is carried out, is otherwise returned
Step 2；
Step 5: control defrosting heater stops working.
Preferably, the temperature for acquiring the defrosting heater retains with compartment temperature.
The invention has the following advantages:
The present invention by from refrigerator carry defrost temperature sensor and compartment temperature sensor control angle, with
The mode for not increasing cost realizes indirect monitoring to refrigeration fan failure, timely and effectively finds refrigeration fan failure, thus
Protect fuse.
Certainly, it implements any of the products of the present invention and does not necessarily require achieving all the advantages described above at the same time.

Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts all other
Embodiment shall fall within the protection scope of the present invention.
Embodiment one:
Refering to Figure 1, the present invention is a kind of fuse protection system based on function refrigerator, including temperature monitoring mould
Block, heater control module and processing module, temperature monitoring module and processing module are electrically connected, and temperature monitoring module will acquire
To temperature data be transferred to processing module；Processing module compares the collected temperature of front and back temperature monitoring module, sentences
Whether disconnected blower works normally；Processing module judges to cease and desist order when fan trouble to heater control module transmission, heater
Control module control heater stops working.
Further, temperature monitoring module includes temperature sensor, and temperature sensor monitors defrosting heater and solely respectively
It renders meritorious service indoor temperature between energy；Processing module is refrigerator controller.
Embodiment two:
It please refers to shown in Fig. 2, a kind of fuse guard method based on function refrigerator includes the following steps:
Step 1, it is heater initial temperature that temperature monitoring module, which acquires defrosting heater surface temperature, acquires independent function
Indoor temperature is compartment initial temperature between energy, and setting heater allows transformation temperature to be T1, and setting compartment allows transformation temperature
It is denoted as T2；
Step 2 acquires indoor temperature between defrosting heater surface temperature and standalone feature after the t time again,
Successively record；
Step 3, collected defrosting heater temperature data, is divided into △ t between the setting reduced time, by △ t before and after the processing
Temperature value before and after time compares, operation, allows to change when the front and back temperature gap of defrosting heater is greater than heater
Step 4 is carried out when temperature T1, otherwise return step two；

Step 2；
Step 5: control defrosting heater stops working.
Further, the temperature for acquiring defrosting heater retains with compartment temperature.
Embodiment three:
Yogurt production is carried out using function refrigerator, when the function program of yogurt production starts to heat compartment, setting
The time interval t of temperature acquisition is 30s, and reduced time interval △ t is 3min, and heater allows transformation temperature T1 to be 7 DEG C, compartment
Allowing transformation temperature T2 is 1.4 DEG C, and in yoghurt function operational process, function compartment be in heated condition, defrosting heater with
Refrigeration fan is being run simultaneously, manually disconnects refrigeration fan route at the 73rd minute, so that refrigeration fan is not normally functioning,
The numerical value for reading defrost temperature sensor and compartment temperature sensor by master control borad is as follows:
| Runing time (min) | Defrosting heater temperature (DEG C) | Function compartment temperature (DEG C) |
| 72.0 | 30 | 26.3 |
