The control unit is respectively electrically connected with the temperature sensor 3 and the refrigeration unit, and the control unit is used for controlling the refrigeration unit to adjust the temperature of the fresh-keeping area to a preset temperature area according to signals transmitted by the temperature sensor 3. The storage object refers to objects such as drinks and foods stored in the fresh-keeping area for fresh keeping, such as meat, fruits, vegetables, milk and the like. The following is a detailed description:
the fresh food section may be one or more of a cold storage compartment, a freezer compartment, and a warming compartment. The physical entity of the crisper zone may be a crisper compartment and/or crisper drawer 1. Now, the preservation drawer 1 is taken as an embodiment to be described in detail, a groove for accommodating the heat conducting plate 2 is formed at the bottom of the preservation drawer 1, and the number of the grooves can be one or more.
The heat-conducting plate 2 is an aluminum plate, and the aluminum plate has better heat-conducting property, and can transmit the heat of stored objects more quickly and accurately. The heat-conducting plate 2 is arranged in the groove of the fresh-keeping drawer 1, and the heat-conducting plate 2 can be one or more than one and is correspondingly arranged in one or more grooves of the fresh-keeping drawer 1. The heat conducting plate 2 is paved on the bottom of the fresh-keeping area so as to be contacted with the stored objects randomly placed in the fresh-keeping area, and therefore the heat of the stored objects is transferred. In other embodiments, the heat conducting plate 2 can be disposed on the side wall and the upper wall of the fresh food area for better contacting and transferring heat of the storage objects placed at the edge of the fresh food area, or for better contacting and transferring heat of the upper surface of the storage objects with higher height.
The temperature sensor 3 may be one or more. When temperature sensor 3 has a plurality ofly, a plurality of temperature sensor 3's probe evenly distributed is on heat-conducting plate 2 to everywhere temperature on the detection heat-conducting plate 2 that can be even, the temperature value of putting into and surveying the deposit of more accurate sense deposit. The temperature sensor 3 may be a thermocouple sensor, an infrared sensor, a radar sensor, or the like. The temperature sensor 3 is in communication connection with the control unit and used for transmitting a temperature signal of the heat conducting plate 2 to the control unit, and the control unit judges whether a storage object is placed in the fresh-keeping area according to the signal and judges whether the refrigeration unit is controlled to work according to the signal so as to refrigerate the fresh-keeping area and adjust the temperature of the fresh-keeping area to a preset temperature area.
Referring to fig. 2, the present invention further provides a method for controlling a fresh-keeping refrigerator, the method comprising: step S1: and detecting the temperature of the stored objects put in the fresh-keeping area. Step S2: and judging whether the temperature of the stored objects is higher than the preset highest temperature of the fresh-keeping area, if so, entering the step S3. Step S3: and starting a fresh-keeping program of the fresh-keeping area, and adjusting the temperature of the fresh-keeping area to be reduced to a preset temperature area of the fresh-keeping area.
The temperature of the contents is typically about room temperature, while the temperature in the fresh food section is below room temperature. When the stored objects are placed in the fresh-keeping area, heat is spontaneously emitted to the fresh-keeping area from the stored objects, the temperature of the whole fresh-keeping area rises, and when the temperature of the whole fresh-keeping area is higher than the preset temperature area, other foods in the fresh-keeping area are gradually deteriorated. At this time, the storage material contacts the heat transfer plate 2, and heat exchange with the heat transfer plate 2 occurs rapidly, and the temperature of the heat transfer plate 2 rises rapidly to the temperature of the storage material, so that the temperature of the heat transfer plate 2 can be regarded as the temperature of the storage material. The temperature sensor 3 detects the temperature of the heat conducting plate 2 in time and transmits the signal to the control unit. The control unit presets a preset maximum temperature and a preset temperature zone of the fresh-keeping zone, wherein the preset temperature zone comprises a maximum value and a minimum value (for example, the preset temperature zone of a temperature-variable chamber for storing meat can be set to be-3 ℃ to 0 ℃). In this embodiment, the preset maximum temperature is equal to the maximum value of the preset temperature zone. And comparing the received signal transmitted by the temperature sensor 3 with the preset maximum temperature, and if the temperature of the stored objects exceeds the preset maximum temperature of the fresh-keeping area, starting a fresh-keeping program to adjust the temperature of the fresh-keeping area to be reduced to the preset temperature area of the fresh-keeping area. If the temperature of the stored objects is detected not to exceed the preset maximum temperature of the fresh-keeping area (for example, the preset maximum temperature is 0 ℃), which indicates that no new stored objects are put into the fresh-keeping area, or that new stored objects are put into the fresh-keeping area but the temperature of the fresh-keeping area is not raised to be outside the preset temperature area, the fresh-keeping area is maintained in the original state. In another embodiment, when the temperature of the stored objects is detected to be lower than the lowest value (for example, the lowest value is-3 ℃) of the preset temperature zone of the fresh-keeping zone, the fresh-keeping zone is started to enter a defrosting mode to raise the temperature to the preset temperature zone, or the fresh-keeping zone is heated to the preset temperature zone.
The preset maximum temperature of the step S2 is equal to the sum of the maximum value of the preset temperature zone and the preset floating temperature difference, and the floating temperature difference is 2-3 ℃.
In a preferred embodiment, a floating temperature differential is also provided (e.g., 2℃), which represents normal temperature fluctuations that can occur in the fresh food section during normal operation. In order to eliminate the false start of the fresh-keeping program caused by the normal temperature fluctuation of the fresh-keeping area under the normal condition, the preset maximum temperature is set as the sum of the maximum value of the preset temperature area and the floating temperature difference (namely 0 ℃ C. +2 ℃ C. =2 ℃). Correspondingly, in another embodiment, when the temperature of the stored objects is detected to be lower than the sum of the lowest value of the preset temperature zone of the fresh-keeping zone and the floating temperature difference (namely-3 ℃ -2 ℃ (= -5 ℃), the fresh-keeping zone is started to enter a defrosting mode to raise the temperature to the preset temperature zone, or the fresh-keeping zone is heated to the preset temperature zone.
Referring to fig. 3, step S3 is preceded by: step S4: judging whether the fresh-keeping area is in a defrosting mode, if so, entering or returning to the step S2 after the defrosting mode is ended; if not, the process proceeds to step S3.
In a preferred embodiment, the refrigerator is provided with a defrosting mode for automatically increasing the temperature after the refrigerator operates for a period of time to melt frost on the condenser. Therefore, a misjudgment may occur and the fresh-keeping program is automatically started. In this embodiment, step S4 is also added before step S3: and judging whether the fresh-keeping area is in a defrosting mode. If the fresh-keeping area is not in the defrosting mode, the temperature rise of the fresh-keeping area is not caused by the defrosting mode, but caused by putting new stored objects into the fresh-keeping area. Therefore, the fresh-keeping program is started to reduce the temperature of the fresh-keeping area to the preset temperature area. If the freshness keeping area is in the defrosting mode, the temperature rise of the freshness keeping area is caused by the defrosting mode, after the defrosting equalization mode is finished, whether the temperature of the stored objects is higher than the preset maximum temperature is judged again, if so, the freshness keeping program is started, and if not, the original state is maintained.

be equipped with the thermal-conductive plate 2 of transmission deposit thing heat in fresh-keeping district, locate heat-conductive plate 2 with temperature sensor 3's probe, the control unit receives temperature sensor 3's signal and controls the temperature that refrigerating unit adjusted fresh-keeping district, can be timely detect the temperature of deposit thing in the fresh-keeping district and detect putting into of deposit thing through temperature sensor 3, thereby start fresh-keeping procedure and adjust the temperature of this fresh-keeping district to presetting warm area, save the trouble that needs the manual regulation fresh-keeping district temperature after putting into new deposit thing in fresh-keeping district. The bottom plate in the fresh-keeping area is arranged on the heat-conducting plate 2 and fully paved at the bottom of the fresh-keeping area, which is beneficial to detecting the putting of the storage object placed at any position of the fresh-keeping area and the temperature of the storage object. The probes of the temperature sensors 3 are uniformly distributed on the heat conducting plate 2, so that the temperature sensors are beneficial to uniformly detecting the temperature of each position on the heat conducting plate 2, and the temperature sensors can sense the stored objects more accurately and measure the temperature values of the stored objects.
By setting the sum of the floating temperature difference and the preset temperature zone to the preset maximum temperature and by providing the step S4 before the starting step S3, it is beneficial to prevent the control unit from starting the fresh-keeping program by mistake, to prevent the temperature of the fresh-keeping zone from being adjusted too low, and to save energy required in the case where the operation of the fresh-keeping program is unnecessarily started.
