Description

Technical Field

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

[0002] With the continuous improvement of living standards and dietary structure, people have higher and higher requirements for the freshness and durability of food. Refrigerators are the terminal for consumers to store food, and people's demand for refrigerators' fresh-keeping function is increasing.

[0003] At present, fresh aquatic products such as hairy crabs, crayfish, and shellfish cannot be eaten on the same day after purchased in large quantities, and there is a need to keep them alive for about 7 days in households.

[0004] There is also a method for keeping aquatic products alive and freezing them in the refrigerator in the technology. For the living aquatic products, the temperature, humidity and oxygen are controlled to keep them alive, and the survival status of the aquatic products is judged. When the aquatic products are on the verge of death, they are frozen to prevent the aquatic products from deteriorating quickly after death. The above method does not accurately control the conditions for keeping aquatic products alive. Taking the temperature for keeping alive as an example, this invention only roughly controls the storage temperature according to the type of aquatic products to provide the living conditions for the aquatic products. For example, shrimps are at about 10°C and crabs are at about 4°C. However, in fact, aquatic products such as shrimps and crabs purchased from the market in a room at room temperature will die due to the sudden change in temperature if they are directly placed in a room at 4°C to 10°C, with a mortality rate of more than 80%. The temperature of fresh aquatic products needs to be cooled at a temperature of about 1°C / hour to keep them alive. Summary of the invention

[0079] See also Figures 1 to 6 In the storage structure of the present embodiment, the storage structure further includes a baffle member, and the baffle member is movably disposed at the communication port 26 to close or open the communication port 26 .

[0080] Specifically, the baffle component includes a left baffle 23, which can slide left and right along the guide rail 25 to close or open the connecting port between the fresh aquatic product storage compartment and the carbon dioxide absorption and release cabin; a right baffle 24, which can slide left and right along the guide rail 25 to close or open the connecting port between the fresh aquatic product storage compartment and the carbon dioxide absorption and release cabin.

[0081] See also Figures 1 to 6In the storage structure of this embodiment, the storage structure further includes a first pipeline 16 , one end of the first pipeline 16 is connected to the storage compartment 1 , and the other end of the first pipeline 16 is connected to the release module 2 .

[0082] With the above arrangement, the first pipeline 16 is used to send the air whose carbon dioxide concentration has been reduced by absorption back to the fresh aquatic product storage room.

[0083] See also Figures 1 to 6 In the storage structure of this embodiment, the storage structure further includes: a drying chamber 5; a second pipeline 17, one end of which is connected to the drying chamber 5, and the other end of which is connected to the release module 2; a third pipeline 19, one end of which is connected to the drying chamber 5, and the other end of which is connected to the storage chamber 1.

[0086] With the above arrangement, fruits and vegetables are stored in the fruit and vegetable compartment 6 , which will produce high-concentration carbon dioxide, and the release module 2 can be used to enrich the carbon dioxide.

[0087] The fourth pipeline 20 is used to transport the high carbon dioxide gas in the fruit and vegetable storage compartment into the drying chamber, and then into the carbon dioxide absorption and release cabin to absorb carbon dioxide.

[0088] The refrigerator of this embodiment includes a storage structure, and the storage structure is the above-mentioned refrigerator.

[0089] The control method of this embodiment is applicable to the above-mentioned refrigerator, and the control method includes: adjusting the temperature in the storage compartment 1 according to the temperature in the storage compartment 1 and the temperature outside the storage compartment 1, so that the temperature in the storage compartment 1 is close to the temperature outside the storage compartment 1; adjusting the temperature in the storage compartment 1 according to the temperature in the storage compartment 1 and the temperature of the surface of the food to be stored, so that the temperature in the storage compartment 1 is close to the temperature of the surface of the food to be stored; adjusting the carbon dioxide concentration in the storage compartment 1 according to the properties of the food to be stored; and adjusting the temperature in the storage compartment 1 so that the temperature in the storage compartment 1 reaches a preset range.

[0090] The above method uses the characteristics of hygroscopic adsorption materials that absorb carbon dioxide under low humidity and release carbon dioxide under high humidity. After the carbon dioxide produced by the respiration of fruits and vegetables or the carbon dioxide gas produced by the respiration of aquatic products in the fruit and vegetable drawer is dried and heated, the hygroscopic material is used to absorb and store carbon dioxide to increase the carbon dioxide concentration in the fresh aquatic storage drawer. In the process of aquatic dormancy and survival, a control method is adopted to first increase carbon dioxide gradually and then decrease the temperature gradually. Carbon dioxide is first released at a higher temperature, which reduces the energy consumption caused by heating due to insufficient temperature for carbon dioxide release, while reducing reaction time and improving efficiency.

[0091] In the control method of this embodiment, adjusting the temperature in the storage compartment 1 according to the temperature in the storage compartment 1 and the temperature on the surface of the food to be stored includes: detecting the average surface temperature H of the food to be stored and adjusting the average temperature L in the storage compartment 1; when HL>X, passing the air outside the storage compartment 1 into the storage compartment 1; when Y<HL≤X, blowing cold air into the storage compartment 1.

[0092] By adopting the above method, the temperature in the storage compartment 1 is adjusted according to different situations, thereby saving energy consumption.

[0093] In the control method of this embodiment, the method of blowing cold air into the storage room 1 includes: dividing the storage room 1 into several areas; identifying whether the food to be stored exists in the storage room 1 in each area; and blowing cold air into the area where the food to be stored does not exist.

[0094] The above setting is adopted to avoid direct blowing of seafood and the like, which may cause damage to food.

[0095] In the control method of the present embodiment, the carbon dioxide concentration in the storage compartment 1 is adjusted according to the properties of the food to be stored; and the method of adjusting the temperature in the storage compartment 1 so that the temperature in the storage compartment 1 reaches a preset range includes: detecting the initial temperature L0 of the aquatic product compartment, the initial surface temperature H0 of the aquatic product, and the initial carbon dioxide concentration B0; according to the type of food to be stored, determining the surface temperature Hz of the food to be stored when it reaches a dormant state, the final temperature Lz (Lz=Hz) of the storage compartment 1, the cooling rate △T, and the carbon dioxide concentration Bz of the food to be stored when it reaches a dormant state; and gradually introducing carbon dioxide into the storage compartment 1, and at the same time, gradually reducing the temperature in the storage compartment 1.

[0096] In this way, the type of aquatic products can be determined through image recognition, and the final storage temperature, cooling rate, storage carbon dioxide concentration, and carbon dioxide increase rate of the aquatic products can be judged. Then, the method of gradient increasing carbon dioxide and gradient decreasing temperature can be adopted alternately to coordinate the control of the cooling rate and the carbon dioxide increase rate, so as to achieve a low-temperature dormancy and survival environment for aquatic products and prevent the death of aquatic products due to sudden changes in the environment.

[0097] In the control method of this embodiment, the method of gradually introducing carbon dioxide into the storage room 1 and gradually reducing the temperature in the storage room 1 includes: detecting the increasing rate of the amount of carbon dioxide in the storage room 1; if the increasing rate of the amount of carbon dioxide is greater than a threshold, absorbing the carbon dioxide in the storage room 1; and / or detecting the decreasing rate of the temperature in the storage room 1; if the decreasing rate of the temperature in the storage room 1 is greater than a threshold, reducing the speed of the refrigeration fan. In this way, it is possible to avoid excessive changes in temperature and carbon dioxide concentration, and the operation is simple and convenient.

[0098] The present invention provides a storage compartment in the refrigerator.

[0099] The specific implementation modes of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are only used to illustrate the present invention but are not used to limit the scope of the present invention.

[0100] Embodiment 1:

[0101] The release module 2 is divided into two working modes: absorption mode and release mode.

[0102] The absorption mode uses the high concentration of carbon dioxide gas in the fruit and vegetable compartment 6 to extract the high concentration of carbon dioxide gas through the drying compartment (the fruits and vegetables in the fruit and vegetable compartment 6 will release moisture, the humidity is high, which is not conducive to carbon dioxide absorption, so it needs to be dried), and the dried gas is absorbed by the material of the release module 2, and the absorbed gas is discharged back to the fruit and vegetable compartment 6. In this mode, the connection between the fresh aquatic storage compartment and the release module 2 is closed, and the connection between the fruit and vegetable compartment 6 and the release module 2 is open. In this mode, the temperature needs to be 20-25°C. If it is lower than 20°C, the electric heating is started, and if it is lower than 25°C, the electric heating is turned off.

[0103] Or when the aquatic products in the fresh aquatic product storage compartment produce carbon dioxide due to breathing, causing the carbon dioxide in the compartment to exceed the preset limit, high-concentration carbon dioxide gas can be extracted through the drying compartment (the humidity of the gas is high, which is not conducive to the absorption of carbon dioxide, so it needs to be dried), and the dried gas is absorbed by the material of the release module 2, and the absorbed gas is transported back to the fresh aquatic product storage compartment through the first pipeline. In this mode, the connection between the fresh aquatic product storage compartment and the release module 2 is open, and the connection between the fruit and vegetable compartment 6 and the release module 2 is closed. In this mode, the temperature needs to be 20-25°C. If it is lower than 20°C, the electric heating is started, and if it is lower than 25°C, the electric heating is turned off.

[0104] The release mode is mainly used to increase the carbon dioxide concentration in the fresh aquatic product storage compartment. In this mode, the connection between the fresh aquatic product storage compartment and the release module 2 is open, and the high-humidity fresh aquatic product storage compartment gas contacts the carbon dioxide adsorption material, thereby releasing carbon dioxide. When the carbon dioxide concentration reaches the preset value, the connection between the fresh aquatic product storage compartment and the release module 2 is closed. In this mode, the temperature needs to be 20-25°C. If it is lower than 20°C, the electric heating is started, and if it is lower than 25°C, the electric heating is turned off.

[0109] The temperature detection unit is used to detect the temperature outside the refrigerator, the indoor air of the fresh aquatic product storage room and the surface of the aquatic products.

[0110] The carbon dioxide detection unit is used to detect the carbon dioxide concentration in the fresh aquatic product storage room.

[0111] The control unit is used to control the opening and stopping of the refrigeration device, the fan device, the humidification device, the carbon dioxide release chamber, and the start and stop of the air pump according to the timing information and the temperature information.

[0134] Determine whether the aquatic position is A3, A4, A1. If so, close the air outlet above the A3, A4, A1 position, and the speed of the A2 fan is M1. Otherwise, proceed to the next step.

[0135] Determine whether the aquatic position is A4, A1, A2. If so, close the air outlet above the A4, A1, A2 positions, and the A3 fan speed is M1. Otherwise, proceed to the next step.

[0136] Determine whether the aquatic position is A1, A2, A3, A4. If so, the air outlet above the A1, A2, A3, A4 position will not be closed, and the fan speed of A1, A2, A3, A4 is M0.

[0137] Step 5: Detect the initial temperature L0 of the aquatic room, the initial temperature H0 of the aquatic surface, and the initial carbon dioxide concentration B0. Image recognition of aquatic species, the control unit determines the aquatic dormant surface temperature Hz, the final temperature Lz (Lz = Hz) of the aquatic dormant room, the cooling rate △T, and the aquatic dormant carbon dioxide concentration Bz.

[0138]

[0139]

[0140] Step 6: Open the carbon dioxide release chamber and detect the carbon dioxide concentration Bn in the aquatic room. When 1 / 6n(Bz-B0)≤Bn≤2 / 6n(Bz-B0), close the carbon dioxide release chamber and proceed to step 7. The value of Bn is B1, B2, B3, B4..., representing the first, second, and third times of gradient reduction of carbon dioxide concentration.

[0141] Step 7: The image recognition unit identifies the aquatic product placement position A, and determines the air outlet position and fan speed M of the aquatic product refrigeration unit through the control unit. The air outlet position and the initial fan speed M are the same as in step 4, and the control unit records the initial cooling time T1.

[0142] Step 8: Detect the temperature Ln of the aquatic product room and determine whether L0-2n△T≤Ln≤L0-n△T.

[0143] If Ln<L0-2n△T, the cooling fan speed M is reduced to 2 / 6 of the previous fan speed; if Ln>L0-n△T, the cooling fan speed M is increased to 7 / 6 of the previous fan speed; until L0-2n△T≤Ln≤L0-n△T, enter step nine.

[0144] Step 9: Detect the surface temperature Hn of the aquatic products. When H0-1.2n△T≤Hn≤H0-0.8n△T, record the time T2 and determine whether the cooling time exceeds 1h.

[0145] If T2-T1<1h, then return to step eight, monitor the compartment temperature and the surface temperature of the aquatic product to be within the preset range, until the cooling time reaches more than 1h, then enter the next gradient cooling and enter step ten.

[0146] If T2-T1≥1h, go to step ten.

[0147] Step 10: Detect the carbon dioxide concentration Bn in the aquatic room. If 1 / 6n(Bz-B0)≤Bn≤2 / 6n(Bz-B0), go directly to step 11; if Bn>2 / 6n(Bz-B0), turn on the carbon dioxide absorption pump. When 1 / 6n(Bz-B0)≤Bn≤2 / 6n(Bz-B0), turn off the carbon dioxide replacement pump. Repeat step 8. When L0-2n△T≤Ln≤L0-n△T, go to step 11.

[0148] This step is mainly because when aquatic products are slowly cooled down, especially when the temperature is high, they will breathe and produce carbon dioxide, causing the previously regulated carbon dioxide concentration to deviate from the optimal value, and need to be readjusted to the appropriate state.

[0149] Step 11: Repeat steps 6 to 10, with n being 1, 2, 3, 4... until the surface temperature of the aquatic products reaches Hz and the carbon dioxide concentration reaches Bz.

[0150] Step 12: Monitor the temperature L of the aquatic product keeping room. If L-Lz>0.5℃, control the fan speed to increase by 6 / 1. If L-Lz<-0.5℃, control the fan speed to decrease by 6 / 1 to maintain -0.5℃≤L-Lz≤0.5℃.
