Description
Technical field
This utility model relates to the fault detection system of not freezing of a kind of single compressor multisystem refrigerator.
Background technology:
Single compressor multisystem refrigerator is complicated due to the more traditional single compressor single system refrigerator refrigeration system of system, in refrigerator use procedure, refrigerator occurs that the failure condition not freezed is more, once after breaking down, user can not find immediately, cause that food spoilage is serious, thus causing customer complaint, affect product quality and brand image.
Utility model content:
This utility model is solve the weak point that above-mentioned prior art exists, provide do not freeze fault detect and the system for prompting of a kind of single compressor multisystem refrigerator, to finding that refrigerator does not freeze fault remind user in time, thus improving product is intelligent and Humanization Level of Municipal.
To achieve the above object of the invention, this utility model adopts the following technical scheme that
The feature of do not freeze fault detect and the system for prompting of this utility model a kind of single compressor multisystem refrigerator includes: some temperature sensors, control unit and transmitting element；
Described some temperature sensors are separately positioned on the evaporator inlet place of each room, and for obtaining each indoor temperature value described；
Described control unit is arranged in control device of refrigerator, and for recording the initial temperature value of each temperature sensor in the detection moment, and within a kind of refrigeration cycle time, detection in real time records each indoor temperature value, when temperature value is higher than set preset value, described control unit sends fault-signal by transmitting element to user mobile phone.
The feature not freezing fault detect and system for prompting described in the utility model lies also in:
Described transmitting element is the WiFi module that refrigerator is built-in.
The described detection moment is: after freezer compressor runs 2 hours continuously.
The one kind of refrigeration cycle time is that cold room, temperature-changing chamber and refrigerating chamber freeze successively, described refrigeration chamber 0-20min, described temperature-changing chamber refrigeration 0-30min, described refrigerating chamber refrigeration 0-15min.
Described preset value is respectively as follows: refrigeration evaporator temperature-5 DEG C, alternating temperature evaporator temperature-15 DEG C, freezing and evaporating actuator temperature-15 DEG C.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
This utility model situation of change by each room evaporator temperature sensor temperature of control unit acquisition and recording, and compare the relation between changing value and preset value, judge that described refrigerator has fault-free, and the fault message detected is sent fault to Client handset end by built-in WiFi module, thus informing user in time, in refrigerator use procedure, not needing manual detection, speed is fast, and efficiency is high, cost is little, and False Rate is substantially zeroed；Avoid the fault that the refrigerator temperature too high rear user of rise could find not freeze, the problem causing food spoilage, and then ensure that the quality of product.

Detailed description of the invention
In the present embodiment, the structural principle of a kind of single compressor multisystem refrigerator is as it is shown in figure 1, include compressor 1, condenser 2, filter 3, electrodynamic valve 4, alternating temperature vaporizer 5, refrigeration evaporator 6 and refrigerating evaporator 7.Based on do not freeze fault detect and the system for prompting of this refrigerator system, as in figure 2 it is shown, include: some temperature sensors, control unit and transmitting element；Transmitting element is the WiFi module that refrigerator is built-in.
Some temperature sensors are separately positioned on the evaporator inlet place of each room, and for obtaining each indoor temperature value；In the present embodiment, it is respectively provided with 3 temperature sensors and is arranged on the porch of vaporizer 7 of the vaporizer 5 of temperature-changing chamber, the vaporizer 6 of cold room and refrigerating chamber；
Control unit is arranged in control device of refrigerator, and for the temperature sensor value that will gather, compares with preset value, it is judged that whether refrigerator breaks down, and then passes through display unit and shows and inform user.Specifically,
The initial temperature value of each temperature sensor is recorded in the detection moment, and within a kind of refrigeration cycle time, detection in real time records each indoor temperature value, and when temperature value is higher than set preset value, control unit sends fault-signal by transmitting element to user mobile phone.
In the present embodiment, the detection moment is: freezer compressor runs 2h continuously.One kind of refrigeration cycle time is that cold room, temperature-changing chamber and refrigerating chamber freeze successively, refrigeration chamber 0-20min, temperature-changing chamber refrigeration 0-30min, refrigerating chamber refrigeration 0-15min.Namely the kind of refrigeration cycle time of open detection is 0-65min.
Preset value is respectively as follows: refrigeration evaporator temperature-5 DEG C, alternating temperature evaporator temperature-15 DEG C, freezing and evaporating actuator temperature-15 DEG C.Being understandable that above-mentioned preset temperature value only exists in the purpose of example, this utility model embodiment is not limited to this, it should set according to practical situation.
Operation principle of the present utility model is:
As it is shown on figure 3, the sensor temperature of step 1, detection refrigerator.
When freezer compressor runs 2h, open detection, control unit record sensor initial temperature value continuously；
Step 2, within a kind of refrigeration cycle time, continue in real time detection record sensor temperature values；
Step 3, a kind of refrigeration cycle terminate, if each sensor temperature is above preset value, then send fault-signal and bind mobile phone to client, such that it is able to long-term detection single compressor multisystem refrigerator ruuning situation in real time, the fault once not freezing occurs in refrigerator, can find in advance, and point out user, time saving and energy saving, efficient quick.
