Refrigerator and its control method

Abstract

The present invention provides a refrigerator and a control method thereof. The refrigerator includes a housing and an air supply duct, the air supply duct being disposed within the housing and having multiple air outlets, at least one of which has an adjustable air outlet direction. The refrigerator and control method provided by the present invention provide multiple air outlets on the air supply duct, enabling uniform distribution of the air outlets. This overcomes the problem in the prior art of providing only two air outlets on the back panel of the refrigerator, resulting in an excessively short air supply distance and an inability to ensure a cooling effect. Furthermore, the adjustable air outlet direction further increases the cooling uniformity of the interior of the housing provided by the air supply duct, thereby further ensuring temperature uniformity within the housing.

Description

Technical Field

[0057] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0058] like Figures 1 to 6 The refrigerator shown includes a housing 1 and an air supply duct 2. The air supply duct 2 is disposed within the housing 1 and is provided with multiple air outlets, at least one of which has an adjustable air outlet direction. Providing multiple air outlets on the air supply duct 2 allows for even distribution of the air outlets, overcoming the prior art problem of only providing air outlets on two sides of the refrigerator back panel, resulting in an excessively short air supply distance and an inability to ensure cooling efficiency. Furthermore, the adjustable air outlet direction further increases the uniformity of cooling provided by the air supply duct 2 within the housing 1, further ensuring temperature uniformity within the housing 1.

[0059] The refrigerator further includes an air guide mechanism, which is disposed at the corresponding air outlet and is capable of adjusting the air outlet direction of the corresponding air outlet. The air guide mechanism guides the airflow at the air outlet, thereby changing the air outlet direction of the air outlet.

[0060] The air guide mechanism includes an air guide column 3, which is rotatably disposed at the air supply port. An air inlet 31 and an air outlet 32 are disposed on the circumferential side of the air guide column 3. Both the air inlet 31 and the air outlet 32 are connected to the interior of the air guide column 3. When air is discharged through the air guide column 3, the air flow enters the air guide column 3 through the air inlet 31 and is finally discharged from the air outlet 32.

[0061] The axis of the air guide column 3 constitutes the rotation axis of the air guide column 3 , and the position of the air outlet 32 is adjusted by rotating the air guide column 3 , thereby achieving a change in the direction of the airflow.

[0062] Preferably, in order to ensure that the air inlet 31 can always be connected with the air supply pipe 2 during the rotation of the air guide column 3, the central angle occupied by the air inlet 31 is greater than the central angle occupied by the air outlet 32. For example, the central angle corresponding to the air inlet 31 ranges from 30° to 60°, and the central angle corresponding to the air outlet 32 ranges from 5° to 10°.

[0063] The air supply port includes a first air supply port 21 and at least one second air supply port 22. The first air supply port 21 is located at the first end of the air supply pipe 2, and the second air supply port 22 is provided on the side wall of the air supply pipe 2. The air guide mechanism is provided at the first air supply port 21. That is, multiple air supply positions are formed along the length of the air supply pipe 2, thereby increasing the uniformity of the airflow in regulating the temperature inside the housing 1.

[0064] The housing 1 has an opening 11, and the air supply pipe 2 is disposed on the inner surface of the housing 1, with the first end of the air supply pipe 2 facing the opening 11. In other words, the air supply pipe 2 replaces the conventional technique of supplying air at the back panel of the housing 1 with a method of flowing air along the inner wall of the housing 1, thereby directing the airflow to the opening 11 as much as possible. In this case, the second end of the air supply pipe 2 is located at the back panel of the housing 1, and air flows from the second end of the air supply pipe 2 to the first end of the air supply pipe 2, thereby further improving the temperature uniformity within the housing 1.

[0065] The refrigerator also includes a first curved pipe section 4, which is disposed at the first end of the air supply duct 2 and forms the first air outlet 21 at the end of the first curved pipe section 4 away from the air supply duct 2. The first curved pipe section 4 redirects the airflow at the first end of the air supply duct 2, thereby increasing the range of airflow regulation at the first air outlet 21 by the air guide mechanism. Preferably, the airflow from the second air outlet 22 is directed toward the first side of the air supply duct 2. The first curved pipe section 4 also directs the airflow from the first air outlet 21 toward the first side of the air supply duct 2, allowing the airflow from the first air outlet 21 and the airflow from the second air outlet 22 to merge.

[0066] The refrigerator also includes a first air guide 5 disposed within the air supply duct 2. The distance between the first air guide 5 and the corresponding second air outlet 22 gradually decreases along the direction of airflow within the air supply duct 2. In other words, the first air guide 5 modifies the flow area of the corresponding portion of the air supply duct 2. As the flow area gradually decreases, a portion of the airflow within the air supply duct 2 is diverted to the corresponding second air outlet 22, thereby ensuring the airflow rate at the second air outlet 22. The first air guide 5 has a triangular cross-section, with the slope of the triangle forming the windward surface of the first air guide 5.

[0067] Preferably, the hypotenuse of the triangle is an arc, and the center of the arc is located outside the triangle.

[0068] The air supply pipe 2 includes a first straight pipe section 23 and a second curved pipe section 24. The second air supply port 22 is provided on the first straight pipe section 23. A third air supply port 25 is provided at the second curved pipe section 24. The air outlet direction of the third air supply port 25 forms an angle with the air outlet direction of the second air supply port 22. The third air supply port 25 further enhances the air outlet effect of the air supply pipe 2. Preferably, the air outlet direction of the third air supply port 25 is vertically upward, while the air outlet direction of the second air supply port 22 is horizontal. In this case, the angle formed by the air outlet direction of the third air supply port 25 and the air outlet direction of the second air supply port 22 is 90°.

[0069] The refrigerator further includes a second air guide 6 having a first guide surface 61 and a second guide surface 62. The first guide surface 61 is capable of directing part of the airflow in the air supply duct 2 to the third air supply port 25, and the second guide surface 62 is capable of directing part of the airflow in the air supply duct 2 to the first straight pipe section 23. The diversion effect of the first guide surface 61 and the second guide surface 62 ensures the airflow out of the third air supply port 25, while also ensuring the airflow out of the first air supply port 21 and the second air supply port 22.

[0070] Specifically, the first guide surface 61 and the second guide surface 62 are both arc surfaces (or partial spherical surfaces), and the connection between the first guide surface 61 and the second guide surface 62 divides the airflow.

[0071] The housing 1 includes a back plate 12 and a side plate 13 , and the second curved pipe section 24 is provided at a connection position between the back plate 12 and the side plate 13 .

[0072] The refrigerator also includes an air intake structure 7, which has an air intake duct formed therein. The air supply pipe 2 is connected to the air intake structure 7, and the second end of the air supply pipe 2 is in communication with the air intake duct. One end of the air intake structure 7 is connected to the refrigerator's fan and other components to direct the cool airflow into the air supply pipe 2.

[0073] There are multiple air supply pipes 2, and all of the air supply pipes 2 are connected to the air inlet structure 7. By providing multiple air supply pipes 2, the air supply positions inside the housing 1 are increased, thereby increasing the accuracy of temperature regulation inside the housing 1.

[0074] The refrigerator further includes a third air guide 8 disposed within the air inlet duct and capable of directing part or all of the airflow within the air inlet duct to the corresponding air supply duct 2. The third air guide 8 directs the airflow within the air inlet structure 7 more smoothly into the corresponding air supply duct 2.

[0075] The number of the third flow guide members 8 corresponds to the number of the air supply pipes 2 , and each third flow guide member 8 introduces a corresponding airflow into a corresponding air supply pipe 2 .

[0076] The housing 1 includes a back plate 12, and the air inlet structure 7 is disposed on the back plate 12. Preferably, a portion of the inner surface of the back plate 12 constitutes a portion of the side wall of the air inlet duct.

[0077] The refrigerator also includes a position detection mechanism, and the air guide mechanism is capable of adjusting the air outlet direction of the first air outlet 21 based on parameters obtained by the position detection mechanism. The position detection mechanism is capable of detecting the position of items within the housing 1. Preferably, the position detection mechanism includes a camera, which can determine the number and position of items placed in the refrigerator by comparing images at previous and subsequent times.

[0078] The refrigerator also includes a temperature detection mechanism. The air guide mechanism can adjust the air outlet direction of the first air outlet 21 based on the parameters obtained by the temperature detection mechanism. The temperature detection mechanism includes multiple temperature sensing packages that can detect multiple areas inside the housing 1, thereby facilitating the determination of the overall temperature inside the housing 1.

[0079] The refrigerator includes: a first side panel 26; a second side panel 27, which cooperates with the first side panel 26 to form the air supply duct 2; and a second air supply port 22 disposed on the second side panel 27. The ends of the first side panel 26 and the second side panel 27 together form the first air supply port 21. Part of the inner surface of the housing 1 may replace all or part of the first side panel 26.

[0080] At least two accommodating chambers are formed in the housing 1, and each of the accommodating chambers is provided with at least one air supply pipe 2. Preferably, two air supply pipes 2 are provided in each accommodating chamber, and the two air supply pipes 2 are mirror-imaged.

[0081] like Figure 7 As shown, another aspect of the present invention provides a refrigerator control method, which is applied to the refrigerator as described above, and the control method includes:

[0082] Get the placement of the newly added items;

[0083] The air outlet direction of the first air outlet 21 is controlled to be toward the placement location according to the placement location. Since the items have just been placed in the refrigerator, the placement location and the surrounding local area require more cooling capacity for refrigeration. Therefore, the air outlet direction of the first air outlet 21 is adjusted to the placement location, so that the placement location and the surrounding local area receive more cooling capacity and cool down more quickly than other areas, thereby achieving the purpose of reaching the set temperature in the local area around the stored items in the refrigerator compartment in a short time.

[0084] The number of the air supply pipes 2 is at least two, and the air outlet direction of the first air supply port 21 is controlled to be directed toward the placement position according to the placement position, further comprising:

[0085] The intersection of the air outlet directions of at least two of the first air outlets 21 is located at the placement position. The air outlet of two or more first air outlets 21 further increases the cooling speed of the placement position.

[0086] After obtaining the placement of the newly added items, it also includes:

[0087] If the number of newly added items exceeds the set number, the first air outlet 21 is controlled to sweep air. In other words, when the number of items added is too large, it is not meaningful to cool each item individually, and the entire interior of the housing 1 needs to be cooled to ensure the cooling effect for all items.

[0088] The control method further includes: when the temperature of the placement location is less than or equal to the set temperature, controlling the first air outlet 21 to sweep air. Sweeping air means that the first air outlet 21 swings so that the air outlet direction of the first air outlet 21 can evenly cover a sector-shaped range, thereby increasing air flow disturbance within the housing 1, enhancing convective heat transfer, and quickly achieving a uniform temperature within the refrigerator.

[0089] like Figure 8 As shown, another aspect of the present invention provides a refrigerator control method, which is applied to the refrigerator as described above, and the control method includes:

[0090] Obtain temperature values Ta of multiple areas within the refrigeration equipment, and compare each Ta with a preset temperature value T0, where a is a positive integer greater than zero;

[0091] If there is a region where Ta is greater than T0, it indicates that the temperature of the region needs to be lowered, and the air outlet direction of the first air outlet 21 is controlled to be toward the region.

[0092] After obtaining temperature values Ta of multiple areas in the refrigeration equipment and comparing each Ta with a preset temperature value T0, the method further includes:

[0093] If all Ta are less than or equal to T0, indicating that the temperature of all areas inside the shell 1 has reached the set value, the first air supply port 21 is controlled to sweep air to evenly cool the inside of the shell 1 to ensure the cooling effect of the refrigerator.

[0094] like Figure 9 As shown, another aspect of the present invention provides a refrigerator control method, which is applied to the refrigerator as described above, and the control method includes:

[0095] Detecting whether the door of the refrigerator is open;

[0096] If the door is open, then after the door is closed, the air outlet of the first air outlet 21 is controlled to be directed toward the door. After the door is opened, the temperature of the door and its vicinity is necessarily higher than that of other areas inside the housing 1. Therefore, the first air outlet 21 is used to cool the door and its vicinity, thereby quickly cooling the hot air entering through the door and ensuring the cooling effect of the refrigerator.

[0097] After controlling the air outlet direction of the first air outlet 21 to be toward the door body, the method further includes:

[0098] Detecting the temperature T2 at the door body and comparing T2 with the preset temperature value T0;

[0099] When T2 is greater than or equal to T0, indicating that the temperature increased due to the door opening has dropped, the first air supply port 21 is controlled to sweep air.

[0100] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
