Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fresh-keeping control, and in particular to a fresh-keeping control system and a refrigerator. BACKGROUND

[0002] With the continuous improvement of living standards, consumers' requirements for food preservation quality are increasing, and the refrigerator, as the most important food storage device in the family, directly affects the freshness, nutrition retention and eating taste of food. Traditional refrigerators generally use the basic preservation strategy of low-temperature environment to inhibit bacterial reproduction, which has a certain effect on delaying food spoilage, but there are obvious deficiencies in the coordinated regulation of multiple parameters such as air pressure, temperature and humidity in the storage environment, and it is difficult to achieve precise preservation of different characteristics of food, so the preservation effect is not ideal in actual application.

[0003] In the current air-cooled refrigerator, the moisture in the air during the refrigeration process is easy to condense into frost on the surface of the fin evaporator, causing the air humidity inside the refrigerator to drop significantly, often at a low humidity level. This low-humidity environment is particularly detrimental to vegetables, fruits and other foods that require high humidity, easily causing water loss, wilting and texture deterioration, and thus affecting food quality. Some refrigerator products attempt to alleviate food moisture evaporation by using an internal water storage container, but this passive humidification method cannot effectively and stably regulate humidity, and the humidity in the refrigerator fluctuates greatly, which cannot guarantee the long-term stability of food flavor and appearance.

[0004] In addition, the existing humidification technology applied in the refrigerator still has certain limitations. On the one hand, they cannot effectively inhibit the transpiration of fruit and vegetable foods, and the problem of water and nutrient loss has not been properly solved; on the other hand, when the environmental humidity is too high, it is easy to cause a large number of microorganisms to multiply, leading to food spoilage. Therefore, in the design of a refrigerator, a humidity control strategy is needed that can balance the needs of high and low humidity, and has the functions of inhibiting bacteria and moisturizing.

[0005] In the existing technology, some technologies attempt to improve the humidification function of the refrigerator. For example, the existing technology proposes to sense the weight and humidity state of the food in the storage area to determine whether to perform humidification or dehumidification operation, thereby improving the humidity conditions of the closed storage unit to a certain extent. However, this method is still weak in the intelligent decision-making of the humidification strategy, and cannot adaptively adjust the humidification mode and intensity according to the actual water content characteristics of the food and the change of the environmental humidity, which limits its effect in actual application.

[0006] Another technical solution proposes to set a humidification structure in the storage device and cooperate with a moisture-permeable membrane and a fan to realize local humidity regulation, which can improve the moisture level of the storage area to a certain extent. However, this method still cannot accurately regulate the different humidity needs of different foods, and the adaptability and flexibility of its humidification function need to be further improved.

[0007] In summary, the existing refrigerator has the following deficiencies in humidity control:

[0008] The frost phenomenon easily occurs in the refrigeration process of the air-cooled refrigerator, resulting in low humidity in the refrigerator, which cannot meet the demand of fruit and vegetable food for high-humidity storage environment;

[0009] The existing humidification system has limited effect on reducing fruit and vegetable transpiration and nutrient loss, and it is difficult to effectively inhibit microbial growth under high humidity conditions, which easily causes food deterioration;

[0010] The current humidification device generally lacks intelligent control capability, and cannot dynamically adjust the humidification mode and intensity according to the water content characteristics of food and the change of environmental humidity, so it is difficult to realize differentiated and precise humidity management, which restricts the further improvement of the preservation performance of the refrigerator.

[0041] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0042] It should be noted that the brief description of the terms in the present application is only for the convenience of understanding the subsequently described embodiments, and is not intended to limit the embodiments of the present application. Unless otherwise specified, these terms should be understood according to their ordinary and general meanings.

[0043] It should be noted that in the present application, the words such as "exemplary" or "for example" are used to represent an example, illustration or description. Any embodiment or design scheme described as "exemplary" or "for example" in the present application should not be interpreted as more preferred or more advantageous than other embodiments or design schemes. Rather, the words such as "exemplary" or "for example" are intended to present the relevant concept in a specific manner.

[0044] Figure 1 A schematic view of a fresh-keeping control system.

[0045] Referring to Figure 1 It can be seen that the present embodiment provides a fresh-keeping control system, which comprises:

[0046] The chamber humidity acquisition module 100 is configured to acquire real-time chamber humidity of the special zone chamber.

[0047] Specifically, in the present embodiment, the humidity of the special zone chamber is monitored by controlling the humidity of the special zone chamber of the refrigerator to preserve the food materials stored in the special zone chamber, and therefore the humidity of the special zone chamber needs to be monitored. The chamber humidity acquisition module 100 is provided to acquire real-time chamber humidity of the special zone chamber, so as to realize the monitoring of the humidity of the special zone chamber.

[0048] It should be noted that the chamber humidity acquisition module 100 monitors the humidity of the special zone chamber once every preset time, and does not continuously acquire humidity data, so as to not only meet the monitoring of the humidity but also save power resources to a certain extent.

[0049] The system further comprises:

[0050] The chamber humidity judgment module 200 is configured to perform humidity judgment according to the real-time chamber humidity and a chamber humidity threshold value, and when the special zone chamber needs to be subjected to humidification treatment, generate corresponding humidification control instructions according to the water content rate of the food stored in the special zone chamber.

[0051] Specifically, in the embodiment, since different food materials have different humidity requirements, different humidification treatments of different degrees need to be performed on the stored different food materials.

[0052] The chamber humidity judgment module 200 judges the obtained real-time chamber humidity, so as to know whether the humidity in the current special zone chamber is less than the chamber humidity threshold value, so as to perform subsequent humidification treatment or maintain the status quo.

[0053] Among them, according to the above-mentioned, different food materials have different humidity requirements, and the "intensity" of humidification treatment of different food materials is also different, so the embodiment also needs to perform humidification of different "intensity" according to the water content rate of the food material, that is, generate corresponding humidification control instructions through the water content rate of the food stored in the special zone chamber.

[0054] It should be noted that the "humidification degree" and "humidification intensity" in the above are completely different concepts. The "humidification degree" can be understood as keeping the humidity at, for example, 90%, while the "humidification intensity" is reflected in the speed of humidification treatment. The food material with high water content rate needs to keep the preset humidity at all times, so the humidification treatment of such food material needs to be fast, so as to avoid the problem that the freshness of the food material rapidly decreases due to the decrease of the water content rate caused by the change of the humidity.

[0055] The system further comprises:

[0056] The chamber preservation execution module 300 is configured to perform humidification treatment of corresponding power and apply electric field treatment to the special zone chamber according to the humidification control instructions.

[0057] Specifically, in the embodiment, after the chamber humidity judgment module 200 generates the corresponding humidification control instructions, a matching execution component is needed to execute the control instructions, so the chamber preservation execution module 300 is set, and the chamber humidity judgment module 200 executes the humidification control instructions issued by the chamber humidity judgment module 200 through the chamber preservation execution module 300, so as to realize humidification treatment and apply electric field treatment, thereby keeping the freshness of the food material stored in the special zone chamber.

[0058] It should be noted that since different ingredients require different humidification treatments, the compartment preservation execution module 300 needs to perform different power humidification treatments on the dedicated compartments according to different humidification control commands, so as to achieve preservation suitable for different types of ingredients.

[0059] Figure 2 This is a schematic diagram of the humidity judgment module in the intermediate chamber of a food preservation control system according to this application.

[0060] See Figure 2 It can be seen that, further, in some embodiments, the room humidity judgment module 200 includes:

[0061] The data judgment unit 210 is configured to determine whether the real-time room humidity is less than the room humidity threshold; if so, it generates humidification information.

[0062] Specifically, in this embodiment, the data judgment function and instruction generation function of the room humidity judgment module 200 are divided into two units. The data judgment unit 210 judges the real-time room humidity and the room humidity threshold. The judgment method is to judge whether the real-time room humidity is less than the room humidity threshold. When the real-time room humidity is less than the room humidity threshold, the special room needs to be humidified. If the real-time room humidity is not less than the room humidity threshold, the special room does not need to be humidified.

[0063] It should be noted that when humidification is required for the special room, the subsequent units need to be informed to generate relevant instructions. Therefore, the data judgment unit 210 needs to use the information to be humidified, which includes the intensity of the humidification process.

[0064] It should be noted that the humidity threshold of the compartment is not constant. The humidity threshold of the compartment is determined according to the type of food stored in the compartment. It can be understood that when the humidity required by the food stored in the compartment is low, the humidity threshold of the compartment is reduced accordingly, while if the humidity required by the food stored in the compartment is high, the humidity threshold of the compartment needs to be increased accordingly.

[0065] The specific method for adjusting the humidity threshold of the room will not be elaborated in this embodiment, as long as the humidity threshold of the room can meet the adaptive change requirement.

[0066] The room humidity determination module 200 further includes:

[0067] The instruction generating unit 220 is configured to generate the corresponding humidification control instruction according to the humidification information and the water content of the food stored in the special compartment.

[0068] Specifically, in the present embodiment, after the data judging unit 210 generates the humidification information, the data judging unit 210 sends the humidification information to the subsequent instruction generating unit 220, and the instruction generating unit 220 generates the corresponding humidification control instruction according to the humidification information and the water content of the food stored in the special compartment.

[0069] Further, in some embodiments, the compartment humidity judging module 200 further comprises an information input unit 230, which is configured to set the compartment humidity threshold of the special compartment and the water content of the stored food according to the food material information input by the user.

[0070] Specifically, in the present embodiment, when the user stores new food material in the special compartment of the refrigerator, the information input unit 230 can input the information of the stored food material, and the information input unit 230 obtains the water content of the food material and the optimal storage humidity of the food material according to the food material information input by the user, and sends the compartment humidity threshold and the water content of the stored food material to the instruction generating unit 220.

[0071] It should be noted that in order to facilitate the user to input the food material information, the information input unit 230 can be equipped with a display screen, and the user can directly input the information of the food material on the display screen. The information input unit 230 can be connected to the network or have the existing food material categories built-in, and obtain the water content and optimal humidity of the food material according to the name of the food material through the two ways.

[0072] Further, in some embodiments, the compartment humidification executing module 300 comprises:

[0073] The compartment humidification executing unit 310 is configured to perform humidification processing on the special compartment according to the humidification control instruction.

[0074] Specifically, in the present embodiment, the corresponding humidification processing in the humidification control instruction is executed by the compartment humidification executing unit 310 to keep the humidity of the special compartment at the corresponding value.

[0075] The compartment humidification executing module 300 further comprises:

[0076] The compartment electric field executing unit 320 is configured to perform electric field processing on the special compartment according to the humidification control instruction.

[0077] Specifically, in the present embodiment, since the application of an electric field to the food material can reduce the crystallinity inside the food material, it can also play a role in preserving the food material to a certain extent, and therefore the chamber electric field execution unit 320 is arranged to apply an electric field to the special zone chamber through the chamber electric field execution unit 320, so as to prolong the preservation time of the food material.

[0078] Figure 3 A schematic view of a back structure of a refrigerator.

[0079] Referring to Figure 3 It can be seen that, further, in some embodiments, the chamber humidification execution unit 310 includes a first humidification component 311, a second humidification component 312, and a third humidification component 313.

[0080] The first humidification component 311, the second humidification component 312, and the third humidification component 313 are all configured to turn on or off the humidification processing function according to the humidification control instruction.

[0081] Specifically, in the present embodiment, the chamber humidification execution unit 310 is arranged in a structure composed of the first humidification component 311, the second humidification component 312, and the third humidification component 313, and the first humidification component 311, the second humidification component 312, and / or the third humidification component 313 are used to perform humidification processing on the special zone chamber.

[0082] Further, in some embodiments, the chamber humidity threshold includes a high threshold, a medium threshold, and a low threshold, the high threshold corresponds to the chamber humidity threshold of the chamber storing fresh leafy vegetables, the medium threshold corresponds to the chamber humidity threshold of the chamber storing fresh melon and fruit, and the low threshold corresponds to the chamber humidity threshold of the chamber storing fresh root and stem.

[0083] Specifically, in the present embodiment, since different food materials require different degrees of humidification, different food materials are classified as described above, so that different food materials can be humidified to different degrees, and pre-classifying the required humidification degrees of different food materials can also reduce the case of user self-setting, thereby further improving the product experience of the user.

[0084] It should be noted that the high threshold, the medium threshold, and the low threshold described above can also be values adjusted according to the input information of the user, that is, the high threshold, the medium threshold, and the low threshold are all humidification thresholds recommended by the system to the user, and these values can be adjusted by the user.

[0085] Further, in some embodiments, the water content includes a high water content, a medium water content and a low water content; when the fresh food stored in the chamber is leafy fresh food, the water content corresponding to the fresh food is the high water content; when the fresh food stored in the chamber is fruit fresh food, the water content corresponding to the fresh food is the medium water content; when the fresh food stored in the chamber is root fresh food, the water content corresponding to the fresh food is the low water content.

[0086] Specifically, in the present embodiment, the water content of the fresh food corresponds to the required humidification degree of the fresh food, that is, the higher the required humidification degree of the fresh food, the higher the water content of the fresh food. It can be understood that the higher the water content of the fresh food, the higher the required humidification degree of the fresh food, so that whether the inter-humidity threshold or the humidification rate needs to be at a high level to meet the preservation requirements of the fresh food. On the contrary, if the water content of the fresh food is low, the required humidification degree of the fresh food is low, and the inter-humidity threshold or the humidification rate of the fresh food needs to be at a low level.

[0087] Further, in some embodiments, the instruction generation unit 220 is further configured to:

[0088] when the water content of the fresh food is the high water content, generate a first humidification control instruction according to the high water content; the first humidification control instruction is used to drive the first humidification component 311, the second humidification component 312 and the third humidification component 313 to perform humidification processing;

[0089] when the water content of the fresh food is the medium water content, generate a second humidification control instruction according to the medium water content; the second humidification control instruction is used to drive the first humidification component 311 and the second humidification component 312 to perform humidification processing;

[0090] when the water content of the fresh food is the low water content, generate a third humidification control instruction according to the low water content; the third humidification control instruction is used to drive the first humidification component 311 to perform humidification processing.

[0091] Specifically, in the embodiment, the first humidifying component 311, the second humidifying component 312 and the third humidifying component 313 are divided into three humidifying levels in individual or joint operation; when the first humidifying component 311, the second humidifying component 312 and the third humidifying component 313 jointly operate, the humidification degree at this time is the highest, and correspondingly, the moisture content of the food stored in the special compartment at this time is also at a higher level; when only the first humidifying component 311 and the second humidifying component 312 operate, the humidification degree at this time is moderate, and correspondingly, the moisture content of the food stored in the special compartment at this time is also at a moderate level; when only the first humidifying component 311 operates, the humidification degree at this time is lower, and correspondingly, the moisture content of the food stored in the special compartment at this time is also at a lower level.

[0092] Further, in some embodiments, the compartment humidification execution unit 310 further comprises:

[0093] A humidifying air duct 314, the first humidifying component 311, the second humidifying component 312, the third humidifying component 313 and the special compartment are all in communication with the humidifying air duct 314, the humidifying air duct 314 is independent of the refrigeration air duct of the refrigerator, and the humidifying air duct 314 is configured to deliver the humid air provided by the first humidifying component 311, the second humidifying component 312 and / or the third humidifying component 313 into the special compartment.

[0094] Specifically, in the embodiment, the humid air provided by the first humidifying component 311, the second humidifying component 312 and / or the third humidifying component 313 is delivered into the special compartment through the humidifying air duct 314, so as to realize humidification treatment of different degrees.

[0095] Further, the embodiment also provides a refrigerator, which comprises a refrigerator body, a refrigerator door body, a refrigeration compartment, a freezing compartment and a special compartment, and further comprises the above-mentioned fresh-keeping control system.

[0097] 1. According to the moisture content of food, the humidification and electric field devices are started to realize precise control of the humidity in the refrigerator, effectively solve the problem of too low humidity in the traditional refrigerator, improve the relative humidity in the refrigerator, and meet the fresh-keeping needs of vegetables and fruits in a high-humidity environment;
