Description

Technical Field

[0001] The present invention relates to the field of refrigerators, and in particular to a refrigerator and a refrigerator control method. Background Art

[0002] In the daily use of refrigerators, users often face the problem of high initial temperature of stored items, especially when dealing with leftovers from meals, newly prepared but not yet eaten food, and food that needs to be cooled and formed. If these high-temperature stored items are placed directly in the refrigerator, not only will the internal temperature of the refrigerator rise significantly in a short period of time, affecting the preservation status of other stored items, but it will also increase the operating burden of the compressor and shorten its service life. At the same time, the odor emitted by high-temperature food is easy to mix with the odor of other stored items, causing odor and other problems, seriously affecting the hygiene of the internal environment of the refrigerator and the freshness of the food.

[0003] In order to avoid the above problems, users usually need to preliminarily cool the high-temperature stored food first, and then put it into the refrigerator after its temperature drops to a certain level. This method is cumbersome, time-consuming and labor-intensive, and brings inconvenience to users. In addition, if the cooling time is insufficient, the food temperature is still high, which is easy to breed bacteria and affect food safety.

[0004] On the other hand, during the use of the refrigerator, users also need to defrost and warm up the stored food. Traditional thawing methods usually involve natural thawing at room temperature or soaking in cold water. These methods are not only time-consuming, but also easily lead to loss of food nutrients and poor taste. If a microwave oven is used for thawing, although the speed is faster, it may cause overheating of some areas of the food due to uneven heating, affecting the thawing effect.

[0005] Whether it is the cooling or thawing process, the traditional thawing and refrigeration solutions require a lot of extra energy, which increases the energy consumption of refrigerators. With the improvement of people's environmental awareness and the increasing tension of energy consumption, how to reduce refrigerator energy consumption and improve energy efficiency has become an urgent problem to be solved in the refrigerator industry.

[0037] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0038] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0039] Prior art CN 107726699 A proposes a refrigerator, which includes a box body, a door and a connection control device. The side wall of the box body is provided with a refrigerating chamber, a heat dissipation chamber and a freezing chamber in sequence. The door includes an insulated door and a timed ventilated door. The front ends of the refrigerating chamber and the freezing chamber are provided with insulated doors respectively. The front end of the heat dissipation chamber is provided with a timed ventilated door. The timed ventilated door includes a door body, a ventilated door core and a deceleration reset device. The door body is rotatably arranged at the front end of the heat dissipation chamber. A through hole is provided in the middle of the door body surface. The ventilated door core is installed in the through hole of the door body. A deceleration reset device is provided between the ventilated door core and the door body. A connection control device is also provided between the refrigerating chamber and the heat dissipation chamber. The present invention opens up an independent heat dissipation chamber in the refrigerator, dissipates heat first and then refrigerates, which not only protects the refrigerator, prolongs the service life of the refrigerator, but also saves people's time. It is simple and efficient and has good feasibility.

[0040] However, the comparative document only provides cooling and ventilation for the cooling room of hot dishes. In daily life, not only do hot dishes need to be cooled in advance, but frozen dishes also need to be thawed. Each compartment requires separate refrigeration and heating to meet customer needs. However, the cold and heat in each compartment are excluded and not reused, resulting in higher energy consumption of the refrigerator.

[0041] like Figure 1-2 As shown, the present invention proposes a refrigerator which may have a conventional refrigerating chamber and a freezing chamber, and further comprises a hot food cooling chamber 1 and a thawing chamber 8.

[0042] The hot dish cooling chamber 1 is arranged in the refrigerator, and the inner wall of the thawing chamber 8 is provided with a first interlayer 2. The inner wall of the hot dish cooling chamber 1 is provided with a first interlayer 2, and a heat exchange medium is arranged in the first interlayer 2. That is, the hot dish cooling chamber 1 is a double-layer structure, and a heat exchange medium is arranged between the two walls.

[0043] The thawing chamber 8 is arranged in the refrigerator, and the inner wall of the thawing chamber 8 is provided with a second interlayer 9, and the second interlayer 9 of the thawing chamber 8 is connected to the first interlayer 2 of the thawing chamber 8, and a valve is provided between the thawing chamber 8 and the hot dish cooling chamber 1. By controlling the switch of the valve, whether the interlayer between the hot dish cooling chamber 1 and the thawing chamber 8 is connected is controlled, and when the valve is opened, the first interlayer 2 and the second interlayer 9 are connected.

[0044] The interlayer of the hot dish cooling chamber 1 and the thawing chamber 8 is connected, and a heat exchange medium is arranged in the interlayer. In the present embodiment, the heat exchange medium is water. The specific heat capacity of water is relatively large, and it can exchange heat with the hot dish cooling chamber 1 and the thawing chamber 8, so that the temperature of the hot dish cooling chamber 1 is reduced and the temperature of the thawing chamber 8 is increased. Moreover, since the interlayer of the hot dish cooling chamber 1 and the thawing chamber 8 can be connected, that is to say, the heat exchange medium in the interlayer of the hot dish cooling chamber 1 and the thawing chamber 8 can be mixed. The mixing of the heat exchange medium indirectly causes the hot dish cooling chamber 1 and the thawing chamber 8 to exchange heat, and the temperature of the thawing chamber 8 is increased by the heat of the hot dish cooling chamber 1, and the temperature of the thawing chamber 8 is decreased by the temperature of the hot dish cooling chamber 1. Through heat exchange, the refrigerator can achieve the purpose of cooling and thawing hot dishes with less energy consumption.

[0045] In a further embodiment, the first interlayer 2 is arranged on both sides and the top and bottom of the hot dish cooling chamber 1, and the second interlayer 9 is arranged on both sides and the top and bottom of the thawing chamber 8. The hot dish cooling chamber and the thawing chamber are arranged side by side, and the first interlayer 2 located at the bottom of the hot dish cooling chamber 1 is connected to the second interlayer 9 located at the bottom of the thawing chamber 8. That is, the bottoms of the first interlayer 2 and the second interlayer 9 are connected, so that the heat exchange medium in the first interlayer 2 and the heat exchange medium in the second interlayer 9 can exchange heat. The front sides of the hot dish cooling chamber 1 and the thawing chamber 8 are doors.

[0046] A heating device is also provided in the thawing chamber 8, which heats up the thawing chamber 8 to accelerate the melting of the items in the cooling chamber. The switch of the regulating valve changes the temperature of the heat exchange medium in the interlayer of the hot dish cooling chamber 1 and the interlayer of the thawing chamber 8.

[0047] By providing an interlayer on the inner wall of the hot dish cooling chamber 1 and the thawing chamber 8, and filling the interlayer with a heat exchange medium with high specific heat capacity (such as water in this embodiment), efficient heat exchange between the two spaces is achieved. The excellent heat conduction performance of water is utilized, and heat is effectively stored and transferred through its large specific heat capacity. Through the heat exchange system, the heat released by the hot dish cooling chamber 1 can be utilized by the thawing chamber 8, reducing additional energy consumption. By controlling the opening and closing of the valve, the heat exchange between the hot dish cooling chamber 1 and the thawing chamber 8 can be flexibly controlled.

[0048] For example: when the valve is closed, the temperature of the heat exchange medium in the interlayer of the hot food cooling chamber 1 is A, and the temperature of the heat exchange medium in the interlayer of the thawing chamber 8 is B;

[0049] When the valve is opened, the temperature of the heat exchange medium in the interlayer of the hot dish cooling chamber 1 is (A+B) / 2, and the temperature of the heat exchange medium in the interlayer of the thawing chamber 8 is (A+B) / 2.

[0050] The valve is made of a material with good thermal insulation, ensuring that the heat exchange between the first interlayer 2 and the second interlayer 9 can be well isolated when closed. The valve is mainly composed of a plate-like member that can be turned around a central rotation axis, and the rotation angle of the rotation axis is controlled by a motor. When the plate-like member rotates to be perpendicular to the shell, it can fit with the inner walls of the four sides of the shell, separating the water layer into left and right sides, and realizing the closure of the valve.

[0051] In a further embodiment, the bottom surface of the hot dish cooling chamber 1 and / or the thawing chamber 8 is made of a soft film material. The soft film material allows the items placed in the hot dish cooling chamber 1 or the thawing chamber 8 to better exchange heat with the heat exchange medium in the interlayer. The soft film material can fit tightly to the bottom surface of the items placed in the hot dish cooling chamber 1 or the thawing chamber 8, and the close contact makes the heat exchange between the items and the heat exchange medium in the interlayer more efficient, thereby accelerating the cooling or thawing speed. The soft film material not only improves the heat exchange efficiency, but also brings a more comfortable and convenient use experience to the user. Due to the softness of the soft film, it can adapt to items of different shapes and sizes.

[0052] like Figure 1-2 As shown, in a further embodiment, an air inlet channel 6 and an air outlet channel 5 are provided in the hot dish cooling chamber 1, and an exhaust fan 7 is provided at the air outlet channel 5.

[0053] By introducing the air inlet channel 6 and the air outlet channel 5, an effective air circulation path is formed. This helps to accelerate the air flow in the hot dish cooling chamber 1, thereby improving the cooling efficiency. The exhaust fan 7 can enhance the exhaust capacity of the air outlet channel 5, ensure that the hot air is quickly extracted, and further accelerate the cooling speed. The design of the air circulation path helps to ensure that the temperature distribution in the hot dish cooling chamber 1 is more uniform. This avoids the situation where the temperature is too high or too low in some areas, and improves the consistency of the cooling effect.

[0054] Preferably, the air inlet channel 6 of the present application is connected to the cold air outlet of the refrigerator.

[0055] In a further embodiment, a purple light lamp 3 is provided in the cooling chamber and / or the hot dish cooling chamber 1 .

[0056] The ultraviolet lamp 3 can effectively destroy the DNA structure of microorganisms such as bacteria, viruses, fungi, etc. by emitting high-energy ultraviolet rays, thereby achieving the purpose of sterilization and disinfection. Installing the ultraviolet lamp 3 in the cooling chamber and / or the hot dish cooling chamber 1 can ensure that the air and the surface of the objects in these areas are fully and efficiently disinfected, greatly reducing the risk of food contamination.

[0057] In a further embodiment, a photocatalyst is provided on the inner wall of the hot dish cooling chamber 1 and / or the thawing chamber 8. The photocatalyst can trigger a chemical reaction under the illumination of the ultraviolet lamp 3, generating free radicals with strong oxidizing properties, which can destroy the cell structure of microorganisms such as bacteria and viruses, thereby achieving the effect of sterilization and disinfection. Providing a photocatalyst on the inner wall of the hot dish cooling chamber 1 and / or the thawing chamber 8 can effectively reduce the number of microorganisms in these areas and improve the hygienic safety of food.

[0058] In a further embodiment, the hot dish cooling chamber 1 and the thawing chamber 8 are respectively provided with a temperature sensor 4 for detecting the room temperature of the hot dish cooling chamber 1 and the thawing chamber 8, and the temperature of the heat exchange medium in the interlayer of the hot dish cooling chamber 1 and the thawing chamber 8. The temperature sensor 4 can detect the room temperature of the hot dish cooling chamber 1 and the thawing chamber 8, and the temperature of the heat exchange medium in the interlayer of these regions in real time and accurately. Such precise temperature monitoring is essential to ensure the safety and quality of food. By timely understanding the temperature changes, the operator can adjust the switch of the valve and the switch of the heating device to adjust the temperature of the hot dish cooling chamber 1 and the thawing chamber 8.

[0059] Preferably, the heating device in the present application is a heating wire.

[0060] like Figure 3-5 As shown, the present invention also proposes a refrigerator control method. When executing the refrigerator control method of the present application, the refrigerator of the present application is used. The refrigerator control method includes the steps of:

[0061] like Figure 4As shown, it is determined whether there are items in the hot dish cooling chamber 1 and the thawing chamber 8; when there are items in the hot dish cooling chamber 1 and / or the thawing chamber 8, the valve between the hot dish cooling chamber 1 and the thawing chamber 8 is opened; that is, the following process is executed only when there are items in at least one of the hot dish cooling chamber 1 and the thawing chamber 8, and the refrigerator control method of the present application does not need to be executed if there are no items. To determine whether there are items, a laser sensor or a gravity sensor can be set to confirm whether there are items in the hot dish cooling chamber 1 and the thawing chamber 8. If there are items in the hot dish cooling chamber 1 and / or the thawing chamber 8, the valve is opened to mix the heat exchange medium in the interlayer of the hot dish cooling chamber 1 and the thawing chamber 8. If there are items in only one of the hot dish cooling chamber 1 or the thawing chamber 8, the mixing of the heat exchange medium can make it absorb more cold or heat. If there are items in both the hot dish cooling chamber 1 and the thawing chamber 8, the mixing of the heat exchange medium can indirectly allow the two chambers to exchange heat, fully utilize the energy, and save the energy consumption of the refrigerator.

[0062] Get the temperature T1 of the heat exchange medium in the interlayer of the hot dish cooling chamber 1 and the temperature T2 of the heat exchange medium in the interlayer of the thawing chamber 8. When the temperature T1 is equal to the temperature T2, close the valve. By monitoring and comparing the temperatures of the heat exchange medium in the two chambers, when they reach equilibrium (i.e., T1 is equal to T2), close the valve in time. This avoids unnecessary heat exchange.

[0063] like Figure 5 As shown, in a further embodiment, after executing the step of closing the valve, the step further includes: according to whether there are objects in the hot dish cooling chamber 1 and the thawing chamber 8, the controller of the refrigerator controls the hot dish cooling chamber 1 to execute the air cooling process and the thawing chamber 8 to execute the heating process. Specifically, if there are objects only in the hot dish cooling chamber 1, the hot dish cooling chamber 1 executes the air cooling process for cooling; if there are objects only in the thawing chamber 8, the thawing chamber 8 executes the heating process for thawing; if there are objects in both the hot dish cooling chamber 1 and the thawing chamber 8, the hot dish cooling chamber 1 executes the air cooling process and the thawing chamber 8 executes the heating process.

[0064] The controller of the refrigerator controls the air cooling process of the hot dish cooling chamber 1 to cool and the heating process of the thawing chamber 8 to thaw according to the actual situation of whether there are items in the hot dish cooling chamber 1 and the thawing chamber 8. For example, when there are items in the hot dish cooling chamber 1 that need to be cooled, the air cooling process is started; when there are items in the thawing chamber 8 that need to be thawed, the heating process is started. This on-demand control method helps to reduce the energy consumption of the refrigerator and improve the energy efficiency ratio.

[0065] In a further embodiment, the hot dish cooling chamber 1 performs an air cooling process, including the steps of:

[0066] Open the air inlet channel 6 and the air outlet channel 5 of the hot food cooling chamber 1, and turn on the exhaust fan 7;

[0067] Get the temperature T11 in the hot food cooling chamber 1;

[0068] When the temperature T11 is greater than the first temperature preset value, the rotation speed of the exhaust fan 7 is adjusted according to the temperature T11; the rotation speed of the exhaust fan 7 is proportional to the difference between the temperature T11 and the first temperature preset value.

[0069] When the temperature T11 is less than or equal to the first temperature preset value, the exhaust fan 7, the air inlet duct and the air outlet duct are turned off.

[0070] By opening the air inlet channel 6, the air outlet channel 5 and the exhaust fan 7, the heat is effectively taken away from the cooling chamber, thereby achieving rapid cooling. The speed of the exhaust fan 7 is adjusted in real time according to the temperature to ensure the efficiency of the cooling process. When the temperature is high, the fan speed increases to speed up the cooling speed; when the temperature is close to the target value, the fan speed decreases to avoid overcooling.

[0071] In a further embodiment, the thawing chamber 8 performs a heating process, comprising the steps of:

[0072] Obtaining the temperature T22 in the thawing chamber 8;

[0073] When the temperature T22 in the thawing chamber 8 is lower than the second preset temperature, the heating device is turned on;

[0074] When the temperature T22 in the thawing chamber 8 is greater than or equal to the second preset temperature, the heating device is turned off.

[0075] By acquiring the temperature T22 in the thawing chamber 8 in real time, accurate control of the thawing process can be achieved.

[0076] In a further embodiment, when the air cooling process and / or the heating process is executed, the ultraviolet lamp 3 is turned on. When the air cooling process and / or the heating process is executed, it is proved that there are items in the hot dish cooling chamber 1 and / or the thawing chamber 8 at this time, and the ultraviolet lamp 3 is turned on to sterilize them with ultraviolet rays.

[0077] Compared with the prior art, the present invention provides a refrigerator, comprising a hot dish cooling chamber 1 and a thawing chamber 8. The inner wall of the hot dish cooling chamber 1 is provided with a first interlayer 2, and the thawing chamber 8 is provided with a second interlayer 9. The first interlayer 2 and the second interlayer 9 are filled with heat exchange medium, and the first interlayer 2 and the second interlayer 9 are connected, and a valve is provided at the connection; when the valve is opened, the heat exchange medium in the first interlayer 2 and the heat exchange medium in the second interlayer are exchanged, and the temperature of the thawing chamber 8 is increased by the heat of the hot dish cooling chamber 1, and the temperature of the thawing chamber 8 is reduced by the temperature of the hot dish cooling chamber 1. Through heat exchange, the refrigerator can achieve the purpose of cooling and thawing hot dishes with less energy consumption, and fully utilize the heat and cold of the hot dish cooling chamber 1 and the thawing chamber 8, thereby reducing the energy consumption of the refrigerator.
