Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of refrigerators, and in particular to a deodorization device, a refrigerator and a deodorization method thereof. BACKGROUND

[0002] Some foods with pungent smell such as durians and some foods that need to retain original smell such as tea leaves are often stored in a refrigerator, which causes odor cross-contamination between the two types of foods and affects the food quality. The existing refrigerator generally places a deodorization block in the refrigeration air cover to deodorize the interior of the refrigerator. However, the deodorization mode cannot be adjusted according to the actual situation, resulting in poor deodorization effect. SUMMARY

[0003] The present application aims to provide a deodorization device, a refrigerator and a deodorization method thereof, which can adjust the deodorization mode according to the actual situation and improve the deodorization effect.

[0004] To this end, in a first aspect, the present application provides a deodorization device applied to a refrigerator, which comprises: a box cover having a cavity in communication with an air duct of the refrigerator and an air outlet hole in communication with the cavity; a sliding block slidingly arranged in the cavity of the box cover to form multiple gears; and a deodorization block arranged on the sliding block, which slides with the sliding block to move away from or cover at least part of the air outlet hole.

[0005] In a possible implementation, a strip-shaped hole is arranged on the box cover, and the sliding block is correspondingly provided with a knob extending into the strip-shaped hole. The sliding block slides along the length direction of the strip-shaped hole through the knob to form multiple gears.

[0006] In a possible implementation, the deodorization device further comprises a detection module. The detection module sends electrical signals to a fan and a compressor of the refrigerator according to the gear in which the sliding block is located.

[0007] In a possible implementation, the detection module comprises: a resistance rod arranged in the cavity along the length direction of the strip-shaped hole; an electrical connection component arranged on the sliding block, which is electrically connected with the resistance rod; and a reading unit electrically connected with the electrical connection component and the resistance rod. The reading unit reads the corresponding resistance value of the resistance rod according to the gear in which the sliding block is located. The detection module sends different electrical signals to the fan and the compressor according to the resistance value.

[0008] In a possible implementation, the multiple gears include: fast cooling, long-acting deodorization and fast deodorization. When the sliding block is located in the fast cooling gear, the reading unit reads the resistance value R of the resistance rod as: R≥15Ω. When the sliding block is located in the long-acting deodorization gear, the reading unit reads the resistance value R of the resistance rod as: 5Ω

[0009] In one possible implementation, the resistance rod includes an insulating cylinder and a resistance wire wound around the outer surface of the insulating cylinder; the connection assembly has a conductive part electrically connected to the resistance wire, one end of the control module is electrically connected to the resistance wire, and the other end is electrically connected to the conductive part, for detecting the resistance value of the part of the resistance wire connected to the circuit.

[0010] Secondly, this application provides a refrigerator, including: a body having a liner and an air duct communicating with the liner; and the aforementioned odor removal device, the cover of which is communicating with the air duct; a compressor and a fan for adjusting the corresponding speed according to the setting of the odor removal device, so as to drive air to circulate in the liner and the air duct.

[0011] Thirdly, embodiments of this application provide a method for deodorizing the refrigerator described above, comprising: acquiring the ambient temperature outside the refrigerator; determining the reference speed of the compressor and the reference speed of the fan based on the ambient temperature; acquiring the gear information of the deodorizing device; and adjusting the speed of the compressor and the speed of the fan based on the gear information of the deodorizing device.

[0012] In one possible implementation, the odor removal device has three settings: long-lasting odor removal, rapid cooling, and rapid odor removal. Adjusting the compressor and fan speeds based on the odor removal device's setting information includes: if the setting is long-lasting odor removal, the compressor and fan speeds remain at a base speed; and / or, if the setting is rapid cooling, a rapid cooling program is executed, adjusting the compressor and fan speeds to their maximum speeds, running for a preset time, and then the compressor returns to the base speed; adjusting the fan speed to one level below the base speed, or maintaining the minimum speed; and / or, if the setting is rapid odor removal, the compressor speed remains unchanged, but the compressor upgrade time is shortened, adjusting the fan speed to one level above the base speed, or maintaining the maximum speed.

[0013] In one possible implementation, the execution of the rapid cooling program includes: if the door is opened for more than a first duration within the preset cooling time, the execution of the rapid cooling program exceeds a second duration, or the power is cut off, the preset duration of the rapid cooling program is recalculated, wherein the preset duration is less than the second duration.

[0014] In one possible implementation, if the rapid cooling program is greater than or equal to a preset duration, the current speed of the compressor and the fan is maintained until the compressor stops.

[0015] According to the odor removal device, refrigerator, and odor removal method provided in the embodiments of this application, the odor removal device adjusts the position of the odor removal block inside the cover by sliding a slider to different positions. The odor removal power is adjusted by adjusting the overlapping area between the odor removal block and the air outlet. Specifically, when the odor removal block is far away from the air outlet, the circulating air does not pass through the odor removal block and is directly discharged through the air outlet, at which time there is no odor removal function. When the odor removal block completely covers the air outlet, the circulating air passes through the entire odor removal block and is discharged through the air outlet, at which time the odor removal power is turned on to the maximum. The odor removal power is positively correlated with the area of ​​the odor removal block covering the air outlet, and the odor removal mode can be adjusted according to the actual situation to improve the odor removal effect.

[0036] To address the problems in the prior art, this application provides a deodorizing device that can adjust the deodorizing mode according to actual conditions to improve the deodorizing effect.

Figure 2 This diagram illustrates the internal structure of an odor-eliminating device according to an embodiment of this application. Figure 3 This diagram shows a cross-sectional view of a deodorizing device provided in an embodiment of this application from a top perspective. Figure 4 This illustration shows a structural diagram of a box cover provided in an embodiment of this application; Figure 5 This illustration shows a schematic diagram of a slider provided in an embodiment of this application; Figure 6 This illustration shows a structural schematic diagram of a power connection component provided in an embodiment of this application; Figure 7 This diagram illustrates the structure of a deodorizing block provided in an embodiment of this application.

[0038] like Figures 1-7 As shown in the embodiment of this application, an odor removal device is provided and applied to a refrigerator. The odor removal device includes: a cover 1 having a cavity 11 communicating with the air duct of the refrigerator and an air outlet 12 communicating with the cavity 11; a slider 2 slidably disposed in the cavity 11 of the cover 1 to form multiple speed settings; and an odor removal block 3 disposed on the slider 2, the odor removal block 3 sliding with the slider 2 to move away from or cover at least part of the air outlet 12.

[0039] In this application, the position of the deodorizing block 3 inside the cover 1 is adjusted by sliding the slider 2 to different positions. The deodorizing power is adjusted by adjusting the overlapping area between the deodorizing block 3 and the air outlet 12. Specifically, when the deodorizing block 3 is far away from the air outlet 12, the circulating air is directly discharged through the air outlet 12 without passing through the deodorizing block 3, and there is no deodorizing function at this time. When the deodorizing block 3 completely covers the air outlet 12, the circulating air passes through the entire deodorizing block 3 and is discharged through the air outlet 12. At this time, the deodorizing power is turned on to the maximum. The deodorizing power is positively correlated with the area of ​​the deodorizing block 3 covering the air outlet 12. The deodorizing mode can be adjusted according to the actual situation to improve the deodorizing effect.

[0040] Specifically, the cover 1 can be made of ABS plastic, which has an insulating effect and is used to connect with the refrigerator liner, so that the cover 1 can be connected to the refrigerator's air duct. Circulating air enters the cover 1 and is discharged through the air outlet of the cover 1.

[0041] In related technologies, existing refrigerator deodorization typically involves placing a deodorizing block 3 inside the refrigerator's air hood. Circulating air blows over the deodorizing block 3, which absorbs odors from the airflow. However, this method cannot adjust the deodorization mode according to actual conditions. For example, when food with a pungent odor is placed in the refrigerator, rapid deodorization is needed, but existing refrigerators cannot adjust this. In this application, a sliding slider 2 is used to increase the coverage area of ​​the deodorizing block 3 over the air outlet 12, thereby increasing the deodorization power and the amount of circulating air it can handle, achieving rapid deodorization.

[0042] In some embodiments, the cover 1 is provided with a strip-shaped hole 13, and the slider 2 is provided with a corresponding lever 21 that extends into the strip-shaped hole 13. The slider 2 slides along the length direction of the strip-shaped hole 13 through the lever 21 to form multiple gear positions.

[0043] In this application, the lever 21 is slidably disposed at the slot 13. By sliding the lever 21, the slider 2 can be driven to slide, allowing the slider 2 to slide to different positions, thereby adjusting the odor-neutralizing level for convenient operation. Specifically, there is a certain friction between the slider 2 and the cover 1. When a pushing force is applied, the slider 2 can be pushed to slide. After adjustment, the friction can keep the slider 2 in the desired position.

[0044] Optionally, the slider 2 can be driven to slide within the housing 1 via a drive component, or driven by an external power source. Specifically, the slider 2 can be driven to slide via an electric push rod.

[0045] In some embodiments, the odor removal device further includes a detection module 4, which sends electrical signals to the refrigerator's fan and compressor respectively according to the position of the slider 2.

[0046] In this application, the position of the slider 2 within the cavity 11 is detected by the detection module 4, i.e., the current setting is obtained, and then the refrigerator fan is adjusted according to the setting. When rapid deodorization is required, the fan speed can be increased to increase the airflow velocity and the air volume passing through per unit time, further improving the deodorization efficiency. At the same time, the airflow volume of the circulating air is guaranteed not to affect the cooling effect, thus achieving an effective balance between cooling and deodorization.

[0047] In some embodiments, the detection module 4 includes: a resistance rod 41 disposed in the cavity 11 along the length direction of the strip hole 13; a power connection component 42 disposed on the slider 2 and electrically connected to the resistance rod 41; and a reading unit electrically connected to the power connection component 42 and the resistance rod 41. The reading unit reads the corresponding resistance value of the resistance rod 41 according to the position of the slider 2. The detection module 4 sends different electrical signals to the fan and the compressor respectively according to the resistance value.

[0048] In this application, the power connection component 42 slides together with the slider 2. The power connection component 42 is electrically connected to the resistance rod 41. By changing the contact position between the power connection component 42 and the resistance rod 41, the resistance of the resistance rod 41 connected to the circuit changes simultaneously. The gear position can be determined based on the resistance value of the resistance rod 41 connected to the circuit. Then, the detection module 4 sends different electrical signals to the fan and compressor respectively based on the resistance value to adjust the speed of the fan and compressor.

[0049] In some embodiments, the multiple settings include: rapid cooling, long-lasting odor removal, and rapid odor removal; when the slider 2 is in the rapid cooling setting, the reading unit reads the resistance value R of the resistance rod 41 as: R≥15Ω; when the slider 2 is in the long-lasting odor removal setting, the reading unit reads the resistance value R of the resistance rod 41 as: 5Ω<R<15Ω; when the slider 2 is in the rapid odor removal setting, the reading unit reads the resistance value R of the resistance rod 41 as: R≤5Ω.

[0050] In this application, the multiple settings include rapid cooling, long-lasting odor removal, and rapid odor removal.

[0051] Rapid cooling: When the deodorizing block 3 leaves the air outlet 12, it does not block the air outlet 12, which can ensure the maximum air volume and thus achieve rapid cooling.

[0052] Long-lasting odor removal: The odor removal block 3 covers part of the air outlet 12, which blocks part of the air outlet 12, reducing the air volume and combining the cooling effect with the odor removal effect.

[0053] Quick odor removal: The odor removal block 3 completely covers the air outlet 12, completely blocking the air outlet 12. The air volume is minimized, but the best odor removal effect can be guaranteed.

[0054] Specifically, in order to ensure the deodorization effect while maintaining the existing cooling effect of the refrigerator, the detection module 4 adjusts the refrigerator's fan and compressor according to the position of the slider 2, thereby ensuring both the cooling and deodorization effects of the refrigerator. Specifically, during rapid deodorization, since the deodorizing block 3 completely covers the air outlet 12, it has a certain impact on the airflow speed. The normal cooling effect can be maintained by increasing the speed of the compressor and / or fan.

[0055] Optionally, the settings in this application can also be configured with multiple levels between rapid cooling and rapid deodorization, such as level one deodorization, level two deodorization, and level three deodorization. The coverage area of ​​the air outlet 12 is set by the deodorizing block 3.

[0056] It should be noted that the resistance values ​​given in this application are for one of the different ranges, and the division of ranges is not limited to the resistance value range mentioned above.

[0057] In some embodiments, the resistance rod 41 includes an insulating cylinder 411 and a resistance wire 412 wound around the outer surface of the insulating cylinder 411; the power connection assembly 42 has a conductive part 421 electrically connected to the resistance wire 412, one end of the control module is electrically connected to the resistance wire 412 and the other end is electrically connected to the conductive part 421, for detecting the resistance value of the part of the resistance wire 412 connected to the circuit.

[0058] In this application, the insulating cylinder 411 can be a ceramic cylinder, and a resistance wire 412 is wound around the outer surface of the insulating cylinder 411. The resistance wire 412 is spirally wound, and the material of the resistance wire 412 is generally a nickel-chromium alloy with a high melting point and high resistance. The outer surface of the resistance wire 412 is coated with insulating varnish, and the end of the resistance wire 412 is connected to a wire. The conductive part 421 of the electrical connection component 42 is made of copper contacts, and the conductive part 421 is also connected to a wire. The resistance wire 412 has an exposed part along the axial direction of the insulating cylinder 411. The conductive part 421 and the exposed part of the resistance wire 412 abut against each other to achieve electrical connection. The resistance value in the circuit changes as the conductive part 421 abuts against different parts of the resistance wire 412.

[0059] Through the aforementioned detection module 4, the corresponding resistance value can be obtained based on the continuous adjustment of slider 2, thereby accurately adjusting the refrigerator's fan to ensure the refrigerator's cooling and deodorizing effects.

[0060] In some embodiments, the deodorizing block 3 has an adsorption section for adsorbing odors.

[0061] In this application, the deodorizing block 3 absorbs odors passing through it through an adsorption section, thereby achieving a deodorizing effect. The adsorption section can be made of activated carbon. The deodorizing block 3 can be replaced after opening the cover 1.

[0062] The odor removal device adjusts the position of the odor removal block 3 inside the housing 1 by sliding the slider 2 to different positions. The odor removal power is adjusted by changing the overlapping area between the odor removal block 3 and the air outlet 12. Specifically, when the odor removal block 3 is far away from the air outlet 12, the circulating air bypasses the odor removal block 3 and is directly discharged through the air outlet 12, at which point the odor removal function is not available. When the odor removal block 3 completely covers the air outlet 12, the circulating air passes through the entire odor removal block 3 and is discharged through the air outlet 12, at which point the odor removal power is at its maximum. The odor removal power is positively correlated with the area of ​​the odor removal block 3 covering the air outlet 12, and the odor removal mode can be adjusted according to the actual situation to improve the odor removal effect.

[0063] This application provides a refrigerator, including: a body having a cabinet liner and an air duct communicating with the cabinet liner; and the aforementioned odor removal device, the cover 1 of which is communicating with the air duct; a compressor and a fan, used to adjust the corresponding speed according to the setting of the odor removal device, so as to drive the air to circulate in the cabinet liner and the air duct.

[0064] In this application, the compressor generates cooling capacity through the evaporator, and the fan drives air through the evaporator to generate cold air, which then circulates in the air duct and the cabinet liner, thereby cooling the interior of the cabinet liner. Specifically, the cabinet liner has a refrigerator compartment and a freezer compartment.

[0065] Figure 8 This document shows a flowchart of a deodorization method provided in an embodiment of this application.

[0066] Figure 9 This document shows a flowchart illustrating a deodorization method provided in an embodiment of this application.

[0067] like Figure 8 - As shown in Figure 9, this application embodiment provides a method for deodorizing the above-mentioned refrigerator, including:

[0068] S1. Obtain the ambient temperature outside the refrigerator;

[0069] S2. Determine the reference speed of the compressor and the reference speed of the fan based on the ambient temperature;

[0070] S3. Obtain the gear setting information of the odor removal device;

[0071] S4. Adjust the compressor speed and fan speed according to the setting information of the odor removal device.

[0072] In this application, the refrigerator acquires the external ambient temperature each time it is powered on, and determines the reference speed of the compressor and the reference speed of the fan based on the ambient temperature; after 10 seconds, it determines the setting information of the deodorizing device; and adjusts the compressor and fan speeds based on the setting information of the deodorizing device, thereby ensuring both the cooling effect and the deodorizing effect of the refrigerator.

[0073] In some embodiments, the odor removal device has three settings: long-lasting odor removal, rapid cooling, and rapid odor removal. Adjusting the compressor speed and fan speed according to the odor removal device's settings includes:

[0074] S41. If the setting is long-lasting odor removal, the compressor and fan speeds will remain unchanged at the base speed.

[0075] S42. If the setting is rapid cooling, the rapid cooling program will be executed, adjusting the compressor and fan speeds to the maximum speeds. After running for a preset time, the compressor will return to the reference speed; the fan speed will be adjusted to one level below the reference speed, or the minimum speed will be kept unchanged.

[0076] S43. If the setting is quick deodorization, the compressor speed remains unchanged, but the compressor upgrade time is shortened, the fan speed is adjusted to be one level higher than the reference speed, or the maximum speed is kept unchanged.

[0077] Specifically, if the odor removal device is set to long-lasting odor removal, the compressor and fan speeds can remain at the base speed. If the odor removal device is set to rapid cooling, a rapid cooling program will be executed, with the compressor and fan running at the highest level for 6 hours. Afterward, the compressor will return to the base speed, and the fan speed will be reduced by one level (or kept at the lowest level if it is already in the base speed). If the odor removal device is set to rapid odor removal, the compressor speed will remain unchanged, but the compressor upgrade time will be adjusted from 90min / 120min / 150min to 60min, and the fan speed will be reduced from the base speed and increased by one level (or kept at the highest level if it is already in the base speed).

[0078] In this application, the theoretical speed of the compressor and fan is obtained by adjusting the reference speed of the compressor and fan according to the setting of the odor removal device. The theoretical speed of the compressor and fan is compared with the actual speed. If the actual speed of the compressor and fan is less than the theoretical speed, the actual speed of the compressor and fan is adjusted to the theoretical speed. If the actual speed of the compressor and fan is greater than or equal to the theoretical speed, the actual speed of the compressor and fan is maintained until the machine stops. When the machine is started again, the actual speed of the compressor and fan is adjusted to the theoretical speed.

[0079] In some embodiments, the execution of the rapid cooling program includes: if the door is opened for more than a first duration, the cooling exceeds a second duration, or the power is cut off within a preset cooling time, the preset duration of the rapid cooling program is recalculated, wherein the preset duration is less than the second duration.

[0080] In this application, if the refrigerator is opened for more than 60 seconds within 1 hour of cooling, the quick-cooling program lasts for more than 72 hours, or the power is cut off, the quick-cooling timer is reset to zero and the preset duration of the quick-cooling program of 6 hours is recalculated.

[0081] In one possible implementation, if the rapid cooling time is greater than or equal to a preset duration, the current speed of the compressor and the fan is maintained until the compressor stops.

[0082] In this application, if the rapid cooling cycle is greater than or equal to 6 hours, the current speed of the compressor and fan is maintained until the compressor stops, and the actual speed of the compressor and fan is adjusted to the theoretical speed when the compressor is started again.

[0083] In some embodiments,

[0084] In some embodiments, the odor removal method includes:

[0085] S5. When the ambient temperature changes;

[0086] S51. If slider 2 in the odor removal device is in the long-lasting odor removal mode or the fast odor removal mode, the parameters can be adjusted directly.

[0087] S52, the slider 2 of the odor removal device is in the rapid cooling position. If the compressor and fan are in the rapid cooling program, the parameters will be adjusted after the rapid cooling program ends; if the rapid cooling program of the compressor and fan has ended, the parameters will be adjusted directly.

[0088] In this application, when the ambient temperature changes, if the odor-eliminating box component is in the long-lasting odor-eliminating or rapid odor-eliminating mode, the parameters are adjusted directly; if the odor-eliminating device is in the rapid cooling mode and is in the rapid cooling cycle, the parameters are adjusted after the rapid cooling cycle ends (the rapid cooling time is not re-accumulated); if the rapid cooling cycle has ended, the parameters are adjusted directly.

[0089] like Figure 9 As shown, this application provides the following specific embodiments:

[0090] Obtain the ambient temperature outside the refrigerator, and determine the reference speed Sm of the compressor and the reference speed Fn of the fan based on the ambient temperature;

[0091] Read the resistance value R of the part of the circuit where the resistance rod of the odor removal device is connected:

[0092] If R≤5Ω, it proves that the deodorizing device is in the "rapid deodorizing" mode. The theoretical speed Sa of the compressor remains unchanged, i.e., Sa=Sm. The upgrade time of the compressor is adjusted from 90min / 120min / 150min to 60min. The theoretical speed Fb of the fan is one level higher than the reference speed Fn. If it is the highest level, it remains unchanged. That is, if n≤4, then b=n+1; if n=5, then b=n.

[0093] If 5Ω < R < 15Ω, it proves that the odor removal device is in the "long-lasting odor removal" setting. In this case, the speed of the compressor and the fan remains unchanged, that is, the theoretical speed of the compressor is Sa = Sm, and the theoretical speed of the fan is Fb = Fn.

[0094] If R≥15Ω, it proves that the odor removal device is in the "rapid cooling" mode and executes the rapid cooling program. The compressor and theoretical speed Sa and the fan's theoretical speed Fb are all increased to the highest level and run for 6 hours. Then the compressor returns to the reference speed, and the fan is reduced by one level from the reference speed (if it is the lowest level, it remains the same).

[0095] In the fast deodorization and long-lasting deodorization modes, the theoretical speed Sa of the compressor is compared with the actual speed Sx, and the theoretical speed Fb of the fan is compared with the actual speed Fy. If x < a, the actual speed Sx of the compressor is adjusted to Sa; if x ≥ a, Sx is maintained until the compressor stops, and Sx is adjusted to Sa the next time it is started. If y ≥ b, Fy is maintained until the fan stops, and Fy is adjusted to Fb the next time it is started. If y < b, the actual speed Fy of the fan is adjusted to Fb. When the ambient temperature changes, the parameters are adjusted directly.

[0096] In the rapid cooling mode, if the rapid cooling program's running time T < 6 hours, the compressor's actual speed Sx increases to the highest level S8, and the fan's actual speed Fy increases to the highest level F5. If T ≥ 6 hours, Sx and Fy are maintained until the compressor stops. Upon the next startup, Sx is adjusted to Sa, and Fy is adjusted to Fb. If the refrigerator door is opened for more than 60 seconds within 1 hour, or T ≥ 72 hours, or the power is restarted, T is reset to zero; otherwise, T continues to accumulate. When the ambient temperature changes, if it is within the rapid cooling program cycle, the parameters are adjusted after the rapid cooling program ends (the rapid cooling time is not re-accumulated). If the rapid cooling program cycle has ended, the parameters are adjusted directly.
