Tropical fruits are delicious but difficult to store. If stored at normal temperature, the tropical fruits have short fresh-keeping period, can not be eaten and decay, and waste is caused. At present, the temperature of a fruit and vegetable storage room of a refrigerator in the market is generally below 10 ℃, different conditions can be met when fruits are stored, if raw fruits are placed in a common fruit and vegetable storage room, the fruits are ripe slowly and cannot be eaten in a long storage time, and the use of users is inconvenient.

In the related art, a scheme is proposed, wherein a heating assembly is adopted to accelerate ripening of fruits stored in a refrigerator compartment, and after ripening is completed, the fruits enter a fresh-keeping storage mode. Namely, the scheme realizes the ripening function of fruits by heating, but can enter a fresh-keeping storage mode only after the ripening mode is finished, and can not realize the ripening and fresh-keeping functions simultaneously in the same room.

In the related art, a scheme is also provided, wherein a storage box and a heating assembly are arranged in the refrigerator, the storage box can be used for storing fruits and vegetables, and the fruits and vegetables are placed in a storage cavity of the storage box. And a partition plate is arranged in the storage box to divide the storage cavity into a first sub-cavity and a second sub-cavity which are mutually independent and are arranged left and right. The valve divides the cold air channel at the top of the storage cavity into a first sub-air channel and a second sub-air channel and is used for controlling the on-off between the first sub-air channel and the second sub-air channel, the first sub-air channel is arranged corresponding to the first sub-cavity and is communicated with the first sub-cavity through a ventilation channel, and the second sub-air channel is arranged corresponding to the second sub-cavity and is communicated with the second sub-cavity through a ventilation channel. The refrigerating air duct is communicated with one of the first sub-air duct and the second sub-air duct, and the heating component is arranged on the other one of the first sub-air duct and the second sub-air duct. When the second sub-cavity needs to be heated and the first sub-cavity needs to be refrigerated, the valve is closed, the first sub-air duct and the second sub-air duct are blocked, cold air in the refrigeration air duct can be blown into the first sub-cavity through the first sub-air duct to refrigerate the first sub-cavity, the heating component can heat the second sub-cavity, a user can store common fruits and vegetables in the first sub-cavity, and tropical fruits or fruits needing to be cured are stored in the second sub-cavity. When the second sub-cavity needs to be cooled, the valve is opened, the first sub-air channel is communicated with the second sub-air channel, cold air in the refrigerating air channel can be blown into the first sub-cavity through the first sub-air channel, and also can be blown into the second sub-air channel from the first sub-air channel, and is blown into the second sub-cavity through the second sub-air channel, and meanwhile, the first sub-cavity and the second sub-cavity are refrigerated. Through increasing the baffle for a storing box has heating function and refrigeration function simultaneously. However, the structure of the scheme is complex, the heat utilization rate is low, and the first sub-cavity and the second sub-cavity cannot be simultaneously ripening.

The refrigerator according to the embodiment of the present invention will be described below with reference to fig. 1 and 2, in which the same compartment is provided with a double temperature zone by using the hot air flow principle and by a simpler structural design, the heat utilization rate is higher, and ripening and fresh-keeping of tropical fruits are achieved.

It can be appreciated that the refrigerator according to the embodiment of the present invention includes a case, in which a storage compartment 101 is provided, and the storage compartment 101 may be a refrigerating compartment or a temperature changing compartment. Illustratively, the storage compartment 101 of the present embodiment is a refrigerating compartment, and the refrigerating air duct of the refrigerator is communicated with the refrigerating compartment, so that cold air in the refrigerating air duct can be blown into the storage compartment 101, so as to achieve preservation of tropical fruits.

It should be noted that, the storage compartment 101 may be used to place tropical fruits, or other fruits and vegetables, so as to achieve ripening and fresh-keeping.

Referring to fig. 1, a partition plate 102 is provided in a storage compartment 101, the partition plate 102 is located at a central portion of the storage compartment 101, and the partition plate 102 is provided in a horizontal direction so as to partition the storage compartment 101 into a first space 103 and a second space 104 arranged in an up-down direction, the first space 103 being located above the second space 104. And a gap is left between the partition 102 and the inner wall of the storage compartment 101, so that a small amount of air flow can be realized between the first space 103 and the second space 104.

According to the hot air flow principle, the temperature of the hot air is relatively high, the heated volume of the air gradually expands, the density of the air is reduced although the mass of the heated volume is unchanged, and the weight per unit volume is reduced, so that the hot air rises upwards. The temperature of the cold air is low, the heated volume of the air gradually contracts, the air density gradually increases, and the weight of the unit volume becomes heavier, so that the cold air is downwards moved. So that the temperature of the first space 103 is high and the temperature of the second space 104 is low without applying other intervention means, and tropical fruits with different ripeness can be stored separately by using such a temperature difference. For example, less ripe tropical fruit may be placed in the first space 103 to accelerate ripening. The tropical fruits with higher maturity are placed in the second space 104, stored at low temperature, and the storage time is prolonged.

Referring to fig. 1 and 2, it can be understood that the refrigerator according to the embodiment of the present invention further includes a heater 105, where the heater 105 is located at the top of the storage compartment 101, and by turning on the heater 105, the generated heat can be transferred to the first space 103, so that the temperature in the first space 103 is increased, and ripening of tropical fruits is accelerated.

It should be noted that the heater 105 may be disposed at other positions of the storage compartment 101, for example, the heater 105 may be disposed at a rear side of the first space 103 or may be disposed around three sides of the first space 103.

Compared with two schemes arranged left and right in space, the embodiment has the advantages that: as described above, the upper space is higher in temperature than the lower space, and if the two spaces are arranged side by side, the average temperature of the single space will be lower than the temperature of the upper space, and more heat is required for the arrangement of the two spaces side by side when the temperature of the upper space needs to be raised to the same target temperature. For example, before the heater 105 is not activated, two spaces are arranged in the left-right direction, the average temperature of a single space is 10 ℃, and when the temperature needs to be raised to 18 ℃ to accelerate ripening, the space needs to be raised by 8 ℃. The two spaces are arranged along the up-down direction, the average temperature of the upper space is 12 ℃, and when the temperature of the upper space is required to be raised to 18 ℃ to accelerate ripening, the space is required to be raised by 6 ℃. Therefore, the scheme of the embodiment reduces unnecessary heating, and the heat utilization rate is higher.

Referring to fig. 1 and 2, it can be understood that the refrigerator according to the embodiment of the present invention further includes a fan 106 and an upper cover 107, the upper cover 107 is located at the top of the first space 103, the fan 106 and the heater 105 are disposed on the upper cover 107, and the upper cover 107 is provided with a vent 201 communicating with the first space 103. Without vent 201, heater 105 may only be activated to heat first space 103 by heat transfer from upper cover 107, resulting in a lower heat exchange efficiency. After the ventilation holes 201 are added, gas exchange can be performed, and heat exchange efficiency can be improved by heating through heat convection. The flow of gas may be accelerated by the provision of a blower 106.

It is understood that the inner diameter of the vent 201 may be set to 2mm or more and 6mm or less. For example, the inner diameter of the vent 201 may be selected to be 2mm, 3mm, 4mm, 5mm, or 6mm. In practice it was found that when the inner diameter of the vent 201 is smaller than 2mm, the insulation performance of the first space 103 is good, but the temperature rise is slower and the gas flow rate is lower. When the inner diameter of the ventilation hole 201 is greater than 6mm, the heat insulation performance of the first space 103 is poor, and cold air blown into the refrigerating air duct easily flows out of the ventilation hole 201, so that the cooling capacity is lost.

It should be noted that, the blower 106 may also be disposed at other positions of the storage compartment 101, for example, the blower 106 is disposed between the first space 103 and the second space 104.

The fan 106 is different from the refrigerating air duct, the cold air blown into the storage compartment 101 by the refrigerating air duct can reduce the temperature of the storage compartment 101, and the fan 106 accelerates the air flow between the first space 103 and the second space 104, so that the temperature difference between the first space 103 and the second space 104 is reduced, and the first space 103 and the second space 104 can jointly realize ripening or fresh-keeping function.

If the tropical fruits are required to be stored at a lower temperature, for example below 10 ℃, the tropical fruits to be preserved are placed in the first space 103 and the second space 104, the heater 105 and the blower 106 are not started, cold air in the refrigerating air duct is blown into the storage compartment 101, the storage compartment 101 is refrigerated, a low-temperature storage space is provided for the tropical fruits, and the shelf life of the tropical fruits is prolonged. When the temperature of the tropical fruits is required to be moderate, for example, the tropical fruits are stored at the temperature of 10-15 ℃, the heater 105 and the fan 106 are started, and the heater 105 is matched with cold air to properly heat the storage compartment 101 until the temperature in the storage compartment 101 reaches between 10-15 ℃, so that the tropical fruits are not frostbitten, and the tropical fruits are not rotten and deteriorated, and the tropical fruits can be stored. When the tropical fruits need to be ripened, the tropical fruits needing to be ripened are placed in the first space 103 and the second space 104, the temperature in the storage compartment 101 can be heated to 18-22 ℃, the temperature range is the optimal ripening temperature of the tropical fruits, and the ripening of the tropical fruits which are not ripened in the storage compartment 101 can be accelerated, so that the tropical fruits can be quickly brought into an edible state. The refrigerator of the embodiment can prolong the shelf life of the tropical fruits, is beneficial to the storage of the tropical fruits, can accelerate the curing of the tropical fruits, has strong compatibility, multiple functions, convenient use and strong practicability, and meets different use requirements of users.

The fan 106 may be further matched with the heater 105 to enable the first space 103 and the second space 104 to enter a ripening mode and a fresh-keeping mode respectively, so as to achieve ripening and fresh-keeping of tropical fruits in the same storage compartment 101.

When the fruit part to be ripened and the fruit part to be preserved are placed in the first space 103, the fruit to be ripened is placed in the second space 104, the fan 106 is closed, and the heater 105 is controlled to work, so that the temperature in the first space 103 reaches 18-22 ℃; the temperature of the second space 104 reaches 12-16 deg.c. After ripening is completed, the fan 106 is started, the temperature difference between the first space 103 and the second space 104 is reduced, and the temperature of the storage compartment 101 is controlled to be uniform to 10-15 ℃.

Referring to fig. 1 and 2, it can be understood that the case further includes a heat insulating member 108, and the heat insulating member 108 can reduce heat exchange between the heater 105 and other parts of the refrigerator, prevent influence on a refrigerating effect of other compartments, and also facilitate improvement of heat exchange efficiency of the first space 103. The heat preservation member 108 is covered on the periphery of the heater 105 and the fan 106, namely, the heater 105 and the fan 106 are positioned between the heat preservation member 108 and the upper cover plate 107, the heat preservation member 108 is provided with a cavity 109 communicated with the vent 201, and the heater 105 is positioned in the cavity 109. The fan 106 draws air from the interior of the storage compartment 101 into the cavity 109, and creates an air flow in the cavity 109, and the air flow passes through the heater 105 due to the air pressure difference, and the created hot air returns into the storage compartment 101 from the vent 201, thereby completing the air flow circulation.

Referring to fig. 2, it can be understood that the number of the ventilation holes 201 is plural, and the plurality of ventilation holes 201 are disposed around the outer circumferential side of the heater 105, so that the hot wind flowing to the first space 103 is more uniform, which is advantageous for uniformly ripening the tropical fruits in the first space 103.

It will be appreciated that the refrigerator further comprises a first drawer provided in the first space 103 and a second drawer provided in the second space 104. Through setting up two independent drawers, help the classification of fruit to can find the fruit of corresponding class fast, open or close the drawer through the mode of pull, it is convenient to use.

It should be noted that, in addition to the scheme of providing the partition 102 to divide the storage compartment 101 into the first space 103 and the second space 104 shown in fig. 1, other schemes may be adopted to divide the storage compartment 101 into the first space 103 and the second space 104. For example, the refrigerator includes a tray and a drawer, which are located in the storage compartment 101, and the tray is placed on the drawer, a first space 103 is defined between the tray and the top surface of the storage compartment 101, and a second space 104 is defined between the drawer and the tray. The tray top has a first opening and the drawer top has a second opening. The tray slides and sets up in drawer upper portion, and the tray front portion is equipped with a handle, and after the drawer was taken out, the user pulled out or pushed the tray through the handle, realized the back-and-forth slip, can select to take out the food in tray or the drawer.

Referring to fig. 1, it may be understood that the refrigerator further includes a temperature sensor 110, the temperature sensor 110 is disposed on the upper cover 107, the temperature sensor 110 is connected to a main control board of the refrigerator, and the temperature sensor 110 is configured to detect a real-time temperature of the first space 103 and feed back the real-time temperature to the main control board, so that the main control board controls the start and stop of the heater 105 and the fan 106 according to an actual temperature in the first space 103, and the degree of automation is high.

It should be noted that the temperature sensor 110 may be disposed on other sidewalls of the first space 103.

It will be appreciated that in other embodiments, a temperature sensor 110 for detecting the real-time temperature of the second space 104 may also be provided.

The embodiment of the invention provides a control method of a refrigerator, which is applied to the refrigerator in the embodiment, wherein the structure or the component constitution of the refrigerator is described in detail in the embodiment, and is not repeated here. Referring to fig. 3, the control method according to the embodiment of the present invention includes, but is not limited to, step S300.

And step S300, controlling the heater and the fan to be turned on or off in response to receiving the control signal so as to change the working mode of the refrigerator.
