Description

Technical Field

[0001] The invention relates to refrigeration and freezing technology, and in particular to a refrigerator control method and a refrigerator. Background Art

[0002] As refrigerators become more and more common in people's daily lives, users have more and more demands on the functions of refrigerators. For example, people hope that refrigerators are not only used to store ordinary foods that require high humidity, such as fruits, vegetables, and meat, but also to store some dry food ingredients that require a low humidity environment. In order to meet users' needs for dry space and high humidity space, and to avoid wasting space, there is currently a related technology that sets a drawer in the refrigerator that can switch between dry and wet functions to store ingredients with different humidity requirements.

[0003] However, in actual use, when the drawer is set to the drying mode, even if the humidity control therein is very precise, the dry goods in the drawer will still get damp; when the drawer is set to the moisturizing mode, even if the humidity control therein is very precise, the fruits and vegetables in the drawer may still lose a lot of moisture. Regarding this technical problem, those skilled in the art generally believe that the humidity in the drying mode and moisturizing mode of the drawer still does not meet the actual needs of the food. Therefore, they still try to solve the problem from the drying mode and moisturizing mode themselves in order to improve the humidity control therein, but the improvement in the preservation effect of the food is minimal. So far, the cause of the above problems has not been found in the prior art. Summary of the invention

[0004] The inventors realize that the humidity control of the drawer in the wet and dry mode and the moisturizing mode can already meet the storage requirements of the items, and the problem does not lie there. The inventors further creatively realize that the dry and wet mode conversion of the drawer requires a certain amount of time. In most cases, the user will put the ingredients in immediately after setting the wet and dry function of the drawer. However, when it comes to the dry and wet function conversion, the mode of the drawer may not be converted when the ingredients are put in. For example, when the user adjusts the drawer from the moisturizing mode to the dry mode, the humidity in the drawer cannot be immediately reduced. If dry goods are put in immediately at this time, the high humidity in the drawer may cause the dry goods to absorb moisture. When the user adjusts the drawer from the dry mode to the moisturizing mode, the humidity in the drawer cannot be immediately increased. If fruits and vegetables are put in at this time, the fruits and vegetables may lose water due to the low humidity. This is the fundamental reason for the existence of the above-mentioned technical problems pointed out in the background technology.

[0005] To this end, an object of the first aspect of the present invention is to overcome at least one defect of the prior art and to provide a refrigerator control method that can provide users with an accurate time to put items in when switching between the dry and wet functions of the drawer to avoid damage to the quality of the items.

[0006] Another object of the first aspect of the present invention is to facilitate the user to understand the switching process of the drawer mode at any time.

[0007] The second aspect of the present invention aims to provide a refrigerator that can provide users with accurate timing to put items in when the drawer's wet and dry functions are switched to avoid damage to the quality of the items.

[0050] The present invention first provides a control method for a refrigerator. The refrigerator of the present invention includes a dry and wet adjustable drawer, and the drawer has a drying mode and a moisturizing mode with different preset humidity ranges. That is, the preset humidity range of the drawer in the drying mode is different from the preset humidity range of the drawer in the moisturizing mode. Specifically, the preset humidity range of the drawer in the drying mode is lower than the preset humidity range of the drawer in the moisturizing mode. When the drawer is set to the drying mode, the humidity therein is low, and it can be used to store treasures, dry goods, etc.; when the drawer is set to the moisturizing mode, the humidity therein is high, and it can be used to store fruits and vegetables, etc.

[0051] Figure 1 : is a schematic structural diagram of a refrigerator control method according to an embodiment of the present invention. The control method of the present invention comprises:

[0052] Step S10, after receiving a mode switching signal for indicating switching between the dry and wet modes of the drawer, issuing a prompt message for indicating the start of the mode conversion of the drawer;

[0053] Step S20, adjusting the humidity in the drawer according to the setting mode of the drawer after switching indicated by the mode switching signal, wherein the setting mode may be a drying mode or a moisturizing mode; and

[0054] Step S40, when the humidity in the drawer is adjusted to within the preset humidity range corresponding to the set mode, a prompt message is issued to indicate that the mode conversion of the drawer is completed.

[0055] The present invention immediately sends a prompt message after receiving a mode switching signal to remind the user that the mode conversion of the drawer has started, and explicitly or implicitly indicates to the user that the mode conversion of the drawer has just started and has not yet been completed, so it is not appropriate to put items in immediately. When the humidity in the drawer is adjusted to a preset humidity range corresponding to the set mode after the conversion, a prompt message is sent again to remind the user that the mode conversion of the drawer is completed, and explicitly or implicitly indicates to the user that the item can be put in at this time. The control method of the present invention provides the user with prompt information for the start and end of the drawer mode conversion, clarifies the best time to put items in the drawer, and facilitates the user to put items in the drawer at the right time, ensuring better preservation quality of the items and avoiding serious water loss or moisture deterioration of the items due to putting the items in the drawer too early.

[0056] Figure 2 is a schematic structural diagram of a refrigerator control method according to another embodiment of the present invention. In some embodiments, after adjusting the humidity in the drawer and before issuing a prompt message indicating that the mode conversion of the drawer is completed, the control method of the present invention further includes:

[0057] Step S31, obtaining a humidity change in the drawer within a first preset time period after the humidity therein begins to be adjusted;

[0058] Step S32, calculating the remaining time required for the humidity in the drawer to reach a preset humidity range corresponding to the set mode according to the humidity change; and

[0059] Step S33, issuing a prompt message including the remaining time.

[0060] That is to say, in a further embodiment, the present invention also calculates the remaining time required for the humidity in the drawer to reach the preset humidity range corresponding to the setting mode based on the humidity change in the drawer within the first preset time after the humidity adjustment starts, and issues a prompt message containing the remaining time, so that the user can clearly understand the waiting time, avoid the user's impatience or thinking to put the items in the drawer in advance, and improve the user's experience. The applicant recognizes that before the items are put into the drawer, the humidity in the drawer is mainly adjusted by the refrigerator. Therefore, the humidity change speed in the drawer is relatively balanced. The humidity change in the drawer over a period of time can be used to estimate the remaining time required to adjust the humidity in the drawer to the preset humidity range corresponding to its setting mode, and the prediction result is relatively accurate.

[0061] Furthermore, the control method of the present invention further includes:

[0062] The remaining time is updated according to the preset time period.

[0063] The present invention also updates the remaining time according to a preset time period, so that the user can understand the switching process of the drawer mode at any time, further improving the user experience.

[0064] In some embodiments, when the setting mode of the drawer is the drying mode, the step of adjusting the humidity in the drawer may specifically include:

[0065] Continuously blowing cooling air into the drawer after exchanging heat with the refrigerator's evaporator; and / or

[0066] A drying module having moisture adsorption properties is exposed in the drawer.

[0067] Specifically, when refrigerant flows through the evaporator, the temperature of the evaporator is relatively low. When the air flows through the evaporator, it exchanges heat with the evaporator, and the moisture in the air condenses on the evaporator, making the temperature and humidity of the cooling air after heat exchange with the evaporator relatively low. Therefore, the humidity in the drawer can be reduced by continuously inputting low-temperature and low-humidity air into the drawer.

[0068] When the drying module having the moisture absorption performance is exposed in the drawer, the drying module can absorb the moisture in the drawer, thereby reducing the humidity in the drawer.

[0069] It is understandable that in some alternative embodiments, the humidity in the drawer may be reduced by other means.

[0070] In some embodiments, when the setting mode of the drawer is the moisturizing mode, the step of adjusting the humidity in the drawer may specifically include:

[0071] Stop the flow of refrigerant to the refrigerator evaporator and continue to blow return air through the evaporator into the drawer; and / or

[0072] The drawer is covered with a moisture-permeable module that allows moisture to permeate out of the drawer.

[0073] Specifically, when there is no refrigerant flowing through the evaporator, the temperature of the evaporator rises, and the frost condensed on the evaporator tends to melt. At this time, when the return air flows through the evaporator, the heat exchange between the frost on the evaporator and the return air will be accelerated, prompting the frost to sublimate, and the water vapor generated by the sublimation of the frost flows into the drawer together with the return air, realizing rapid humidification of the drawer.

[0074] When the moisture-permeable module having the moisture-permeable property to the outside is covered, the moisture in the drawer cannot flow out of the drawer through the moisture-permeable module, and therefore, the humidity in the drawer can be increased under the humidification effect of other devices.

[0075] It is understandable that in some alternative embodiments, the humidity in the drawer may be increased by other means.

[0076] In some embodiments, the refrigerator further comprises a display screen and / or a sound device. In these embodiments, the prompt information indicating the start of the mode conversion of the drawer may include information displayed on the display screen and / or sound information emitted by the sound device. For example, a text message such as "starting mode conversion" may be displayed on the display screen, and the sound device may emit a voice message such as "starting mode conversion".

[0077] In some embodiments, the refrigerator further comprises a display screen and / or a sound device. In these embodiments, the prompt information indicating that the mode conversion of the drawer is completed includes information displayed on the display screen and / or sound information emitted by the sound device. For example, a text message such as "mode conversion is completed" may be displayed on the display screen, and the sound device may emit a voice message such as "mode conversion is completed" or a single sound message such as "ding" or "dong".

[0078] In some embodiments, the refrigerator further comprises a display screen and / or a sound device. In these embodiments, the prompt information including the remaining time may include information displayed on the display screen and / or sound information emitted by the sound device. For example, the display screen may display text information such as "converting, remaining time 30s", and the sound device may emit voice information such as "converting, remaining time 30s". When the remaining time can be updated at any time, the time displayed on the display screen is also updated at any time.

[0079] After the prompt message indicating that the mode conversion of the drawer is completed is sent, the user puts the item into the drawer. However, the inventors recognize that the user may misidentify the food or misoperate to cause the drawer mode to be set incorrectly. For this reason, in some embodiments, see Figure 3 The schematic structural diagram of the control method of the refrigerator according to another embodiment of the present invention is shown. After issuing a prompt message indicating that the mode conversion of the drawer is completed, the control method of the present invention further includes:

[0080] Step S51, obtaining the humidity in the drawer;

[0081] Step S52, when the humidity in the drawer is continuously outside the preset humidity range corresponding to the set mode within the second preset time period or is within the preset humidity range and then returns to outside the preset humidity range, a prompt message indicating that the mode setting of the drawer is wrong is issued.

[0082] Specifically, the prompt information may include voice information, sound information such as a buzzer, and flashing or predetermined color light information. Of course, the prompt information may also include two or more of the above information at the same time, and may also include display information displayed on a display screen, etc.

[0083] That is to say, after predicting that the user will put the item into the drawer, the present invention will continue to monitor the humidity in the drawer, and judge whether the mode setting of the drawer is wrong according to the humidity in the drawer. If the mode setting of the drawer is wrong, a prompt message will be issued to remind the user that the mode setting of the drawer is wrong, so that the user can correct the setting mode of the drawer in time, so that the setting mode of the drawer matches the actual environment required by the items placed in the drawer, ensuring the better preservation quality of the items and avoiding the serious water loss or moisture deterioration of the items due to the wrong setting of the user.

[0084] The inventors realize that the fundamental reason for classifying and storing different items is that the items themselves contain different amounts of water and need to maintain different amounts of water. The water content of the items themselves is difficult to measure in a simple way, but the effect of the items placed in the drawer on the humidity in the drawer is obvious and easy to measure. For example, after fruits and vegetables are placed in the drawer, the water contained in the fruits and vegetables evaporates, which will increase the humidity in the drawer; after precious dry goods are placed in the drawer, the precious dry goods contain very little water, which will not increase the humidity in the drawer, and when the humidity in the drawer is high, the precious dry goods may also absorb the water in the drawer to reduce the humidity in the drawer. Therefore, the present invention determines whether the drawer mode is set incorrectly based on the humidity in the drawer. It not only conforms to the actual situation, but also has a high accuracy of the judgment result. It does not need to identify and obtain any information about the items placed in the drawer, does not need to process the information of the items, and does not need to set a device for obtaining item information in the drawer. It simplifies the structure in the drawer and the control logic of the refrigerator, and the design idea is relatively novel.

[0085] The present invention judges whether the mode of the drawer is set incorrectly based on the comparison relationship between the humidity of the drawer within the second preset time period and the preset humidity range corresponding to the set mode of the drawer. The judgment result is more accurate and more in line with the actual situation of humidity changes in the drawer.

[0086] Specifically, if the setting mode of the drawer is the drying mode, the above step S52 may specifically include:

[0087] When the humidity in the drawer is continuously greater than the maximum endpoint value of the first preset humidity range corresponding to the drying mode within a first preset time period, or is less than the maximum endpoint value and then recovers to be greater than the maximum endpoint value, a prompt message is issued to indicate that the drawer mode setting is incorrect.

[0088] Specifically, if the setting mode of the drawer is the moisturizing mode, the above step S52 may specifically include:

[0089] When the humidity in the drawer is continuously lower than the minimum endpoint value of the second preset humidity range corresponding to the moisturizing mode within the first preset time period, a prompt message indicating that the mode setting of the drawer is wrong is issued.

[0090] Figure 4 Schematic structure diagram of a control method for a refrigerator according to another embodiment of the present invention is shown. In some embodiments, after issuing a prompt message indicating that the mode setting of the drawer is wrong, the control method of the present invention further includes:

[0091] Step S61, obtaining the humidity in the drawer and the current setting mode of the drawer again after a third preset time period;

[0092] Step S62, when the humidity in the drawer is outside the preset humidity range corresponding to the current setting mode, it is determined that the mode switching of the drawer has failed; and

[0093] Step S63, automatically adjusting the drawer to a mode actually required by the items placed in the drawer.

[0094] The inventors recognize that after the prompt message is sent, the user may manually switch the mode of the drawer, or may not switch the mode of the drawer due to failure to receive the prompt message or other reasons. When faced with the problem of how to detect whether the drawer mode has been successfully switched, it is easier to think of directly detecting whether the mode of the drawer has been switched to the mode that the drawer should have. For example, when the initial mode is the drying mode, and according to the comparison result of step S52, it is concluded that the drawer should be in the moisturizing mode, it is subsequently possible to directly detect whether the current setting mode of the drawer is the moisturizing mode. However, the inventors recognize that the acquisition of humidity in step S51 and the comparison of humidity in step S52 may have errors or even mistakes, which will directly affect the storage quality of items in the drawer.

[0095] To this end, the present invention determines whether the drawer mode is successfully switched again based on the humidity in the drawer and the current setting mode of the drawer after the third preset time period of issuing the prompt information, and can continuously follow up and monitor the mode and humidity of the drawer, so as to automatically switch the mode when its mode does not match the humidity, thereby ensuring that the drawer mode is highly matched with the environment required by the items in the drawer, with a high degree of intelligence and good user experience. It is understandable that the current setting mode of the drawer may be the same as its initial setting mode, at which time the user has not manually switched the drawer mode, or it may be different from its initial setting mode, at which time the user has manually switched the drawer mode.

[0096] In some embodiments, when the drawer is in the drying mode, the corresponding first preset humidity range is 0-50%. When the drawer is in the moisturizing mode, the corresponding second preset humidity range is 85-100%. For the preset humidity ranges of the drawer in the drying mode and the moisturizing mode, the user can appropriately adjust them according to different items.

[0097] The present invention also provides a refrigerator. Figure 5 is a schematic structural diagram of a refrigerator according to an embodiment of the present invention, Figure 6 is a schematic structural block diagram of a refrigerator according to an embodiment of the present invention. Figure 5 and Figure 6 The refrigerator 1 of the present invention includes a dry and wet adjustable drawer 10, a humidity sensor 20 and a control device 30.

[0098] The drawer 10 has a drying mode and a moisturizing mode with different preset humidity ranges. Specifically, the number of the drawers 10 can be one, two or more than two. When the number of the drawers 10 is two, the two drawers 10 are arranged side by side in the box body of the refrigerator 1 in a horizontal direction.

[0099] The humidity sensor 20 is used to obtain the humidity in the drawer 10. Specifically, the humidity sensor 20 can be disposed in the drawer 10 and electrically connected to the control device 30.

[0100] The control device 30 includes a processor 31 and a memory 32 . The memory 32 stores a machine executable program 33 . When the machine executable program 33 is executed by the processor 31 , it is used to implement the control method described in any of the above embodiments.

[0101] The refrigerator 1 of the present application is a refrigerator in a broad sense, which not only includes the so-called refrigerator in a narrow sense, but also includes storage devices with refrigeration, freezing or other storage functions, such as refrigerators, freezers, etc.

[0102] The drawer 10 of the present application is a drawer in a broad sense, which includes not only the so-called pull-out storage device, but also other forms of storage devices with defined storage spaces.

[0103] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all these other variations or modifications.
