Description

Technical Field

[0001] The present application relates to the technical field of refrigerators, and in particular to a heating control method and device for a refrigerator flip beam, and a flip beam heating system. Background Art

[0002] With the continuous improvement of people's living standards, air-cooled refrigerators have entered thousands of households, and refrigerators with double-door refrigerated compartments are becoming more and more common. In existing refrigerators with double-door refrigerated compartments, the two door bodies are closed through a flip beam structure to solve the problem of cold leakage. Usually, the refrigerator flip beam is set on the side wall of any door body. When closing, the user needs to set the flip beam on the door body with the flip beam to a vertical state in advance. When the door body is closed, the flip beam is guided to a horizontal state by the guide structure of the guide seat in the top of the refrigerator box to complete the closing. The horizontal flip beam is sealed with the magnetic strips of the door bodies on both sides of the refrigerator to form a relatively closed space between the box body and the door body to achieve the effect of preserving cold air. However, due to the poor insulation effect at the flip beam, condensation often occurs, which gives users a bad experience.

[0003] In order to solve the condensation problem of the refrigerator flip beam, a heater is usually set to increase the surface temperature of the flip beam and reduce the risk of condensation. In the prior art, more designs are based on a certain heating time to control the heater to automatically turn on and off, to achieve periodic heating of the heater, and to avoid safety hazards caused by continuous heating. For example, when entering the set heating cycle, the control module controls the power supply output power to supply the solid-state switch, so that the solid-state switch is powered on. After the solid-state switch is turned on, the heating control of the refrigerator flip beam controls the flip beam heater to be electrically connected to the live wire access terminal of the heating control AC power supply of the refrigerator flip beam to input the forward working power. At this time, since the reverse power supply terminal of the flip beam heater is connected to the neutral wire access terminal of the AC power supply, the flip beam heater can be heated.

[0004] However, the prior art ignores the fact that during the use of the refrigerator, the flip beam may be flipped up, including normal flipping up when the door is opened or abnormal flipping up after the door is closed. At this time, if time control is still used for heating, it will not only waste electricity, but also there will still be safety hazards caused by high temperature and high pressure.

[0059] In this embodiment, a heating control method for a refrigerator flip beam is provided. The method is applicable to a heating system of a flip beam 31, such as Figure 2 As shown, the system includes a flip detection unit 21, a main control unit 22 and a heating unit 23; the flip detection unit 21 is used to detect the position of the flip beam 31; wherein the flip detection unit 21 generates a first detection signal when the flip beam 31 is in a safe position, and generates a second detection signal when the flip beam 31 is not in a safe position; the main control unit 22 is connected to the flip detection unit 21 and the heating unit 23 respectively.

[0060] The method is applied to the main control unit 22, Figure 3 : is a flow chart of the heating control method of the refrigerator flip beam of this embodiment, such as Figure 3 As shown, the process includes the following steps:

[0061] Step S310 , obtaining a detection signal generated by the flip detection unit 21 .

[0062] Step S320 , when the detection signal is the second detection signal, the heating unit 23 is controlled to stop heating the flip beam 31 .

[0063] Step S330 , when the detection signal is the first detection signal, the heating unit 23 is controlled to start heating the flip beam 31 .

[0064] Specifically, the flip beam 31 is arranged on the side wall of the free end of a door of the refrigerator. When the door of the refrigerator is closed, the flip beam 31 will flip from a vertical position to a horizontal position. The flip beam 31 in the horizontal position cooperates with the magnetic strips of the doors on both sides of the refrigerator to form a relatively closed space between the box and the door to achieve the effect of preserving cold air. When the refrigerator is opened, the flip beam 31 will be flipped up. When the refrigerator door is closed, it may not return to the safe position (i.e., the horizontal position) due to artificial flipping or obstruction by foreign objects, and it may still be in an abnormal flipped position. In this embodiment, the flip detection unit 21 is used to detect the position of the flip beam 31. The flip detection unit 21 can adopt a contact detection unit or a non-contact detection unit, wherein the contact detection unit can adopt a detection unit based on a mechanical switch 211, and the mechanical switch 211 will contact the flip beam 31 flipped to a certain position; the non-contact detection unit can adopt a detection unit based on infrared sensing or electromagnetic induction, which can detect the position of the flip beam 31 during the flipping process of the flip beam 31. This embodiment does not limit the specific implementation method of the flip detection unit 21.

[0065] In this embodiment, the position of the flip beam 31 is detected by the flip detection unit 21; the flip detection unit 21 generates a first detection signal when the flip beam 31 is in a safe position, and generates a second detection signal when the flip beam 31 is not in a safe position; the heating unit 23 is used to heat the flip beam 31; the main control unit 22 is connected to the flip detection unit 21 and the heating unit 23, respectively; the method is applied to the main control unit 22, and the method includes: obtaining the detection signal generated by the flip detection unit 21; when the detection signal is the second detection signal, controlling the heating unit 23 to stop heating; when the detection signal is the first detection signal, controlling the heating unit 23 to start heating, which solves the problem of continuous heating of the flip beam 31, and realizes the selective opening of the heating unit 23 according to the position of the flip beam 31, thereby improving the heating efficiency and reducing the safety hazards caused by high temperature and high pressure.

[0066] In some embodiments, based on step S330, when the detection signal is the first detection signal, controlling the heating unit 23 to start heating the flip beam 31 includes:

[0067] Step S331, when the detection signal is the first detection signal, obtaining the switch state signal of the refrigerator door.

[0068] Step S332, when the switch status signal shows that the refrigerator door is closed, the heating unit 23 is controlled to start heating the flip beam 31.

[0069] Step S333, when the switch status signal shows that the refrigerator door is not closed, an error warning is issued, and the heating unit 23 is controlled to stop heating the flip beam 31.

[0070] Furthermore, the error warning triggers an alarm or a fault indicator light to notify the operator to perform inspection and maintenance.

[0071] In this embodiment, a multiple safety condition judgment mechanism is adopted to ensure that heating is resumed only when all safety conditions are met, thereby greatly improving the reliability of heating control.

[0072] In some of the embodiments, Figure 4 As shown, the flip detection unit 21 includes a mechanical switch 211 and a control circuit 212 ; the mechanical switch 211 is connected to the control circuit 212 , and the control circuit 212 is connected to the main control unit 22 .

[0073] The mechanical switch 211 is pressed by the flip beam 31 in the safe position and is turned on; when the mechanical switch 211 is turned on, the control circuit 212 generates a first detection signal; when the mechanical switch 211 is turned off, the control circuit 212 generates a second detection signal.

[0074] Specifically, the mechanical switch can be a micro switch, a limit switch, etc. These mechanical switches 211 are directly triggered by the movement of the flip beam 31, without the need for electricity or complex control logic. The installation position should ensure that the mechanical switch 211 can be reliably popped up when the flip beam 31 is flipped open, thereby disconnecting the control loop 212.

[0075] In some of the embodiments, Figure 5 As shown, the mechanical switch 211 includes a first contact 2111 , a second contact 2112 , and a button 2113 connected to the second contact 2112 .

[0076] The first contact 2111 and the second contact 2112 are separated from each other when not acted upon by the flip beam 31 .

[0077] When the flip beam 31 is in the safe position, the button 2113 is pressed, and the button 2113 pushes the second contact point 2112 to a position in contact with the first contact point 2111 .

[0078] In some of the embodiments, Figure 6 and Figure 7 As shown, a boss 41 is provided on the inner side of the refrigerator door; the inner side of the refrigerator door is the side facing the refrigerator cavity. One side of the boss 41 is opposite to the flip beam 31 when in the safe position. The mechanical switch 211 is arranged inside the boss 41, and the button 2113 is exposed on the surface of the boss 41 and points to the flip beam 31.

[0079] Figure 6 and Figure 7 A partial enlarged view of the refrigerator door. Figure 6 The middle flip beam 31 is in the flipped position, at which time the mechanical switch 211 pops up, causing the first contact 2111 and the second contact 2112 to separate, and the signal sent by the control loop 212 to the main control unit 22 jumps from a low level to a high level and maintains a high level. Figure 7 The middle flip beam 31 is in a safe position, and the mechanical switch 211 is pressed, so that the first contact 2111 and the second contact 2112 are connected, and the signal sent by the control loop 212 to the main control unit 22 jumps from a high level to a low level and remains at a low level.

[0080] In some of the embodiments, see Figure 5 The mechanical switch 211 further includes an elastic component 2114, and the button 2113 is connected to the second contact 2112 via the elastic component 2114. The elastic component 2114 can be a spring, which provides a buffering and shock absorbing effect when the flip beam 31 resets and squeezes the button 2113, thereby protecting the mechanical switch 211.

[0081] In this embodiment, a heating system for the flip beam 31 is also provided. Figure 2 The system includes a flip detection unit 21, a main control unit 22 and a heating unit 23.

[0082] The flip detection unit 21 is used to detect the position of the flip beam 31 ; the flip detection unit 21 generates a first detection signal when the flip beam 31 is in a safe position, and generates a second detection signal when the flip beam 31 is not in a safe position.

[0083] The heating unit 23 is used to heat the turning beam 31 .

[0084] The main control unit 22 is connected to the flip detection unit 21 and the heating unit 23 respectively; the main control unit 22 is used to implement the steps in any of the above method embodiments.

[0085] In this embodiment, the flip detection unit 21, the main control unit 22 and the heating unit 23 solve the problem of continuous heating of the flip beam, and selectively turn on the heating unit 23 according to the position of the flip beam, thereby improving the heating efficiency and reducing the safety hazards caused by high temperature and high pressure.

[0086] In some of the embodiments, Figure 4As shown, the rollover detection unit 21 includes a mechanical switch 211 and a control circuit 212; the mechanical switch 211 is connected to the control circuit 212, and the control circuit 212 is connected to the main control unit 22. The mechanical switch 211 is pressed by the rollover beam 31 in the safe position and is turned on; when the mechanical switch 211 is turned on, the control circuit 212 generates a first detection signal; when the mechanical switch 211 is turned off, the control circuit 212 generates a second detection signal.

[0087] In some of the embodiments, Figure 5 As shown, the mechanical switch 211 includes a first contact 2111, a second contact 2112, and a button 2113 connected to the second contact 2112. The first contact 2111 and the second contact 2112 are separated from each other when not acted upon by the flip beam 31. When the flip beam 31 is in a safe position, the button 2113 is pressed, and the button 2113 pushes the second contact 2112 to a position in contact with the first contact 2111.

[0088] In some of the embodiments, Figure 6 and Figure 7 As shown, a boss 41 is provided on the inner side of the refrigerator door; the inner side of the refrigerator door is the side facing the refrigerator cavity. One side of the boss 41 is opposite to the flip beam 31 when in the safe position. The mechanical switch 211 is arranged inside the boss 41, and the button 2113 is exposed on the surface of the boss 41 and points to the flip beam 31.

[0089] In some of the embodiments, the mechanical switch 211 further includes an elastic component 2114 , and the button 2113 is connected to the second contact 2112 via the elastic component 2114 .

[0090] Figure 8 1 is a flow chart of the heating control method of the refrigerator turning beam of the preferred embodiment. The present embodiment is described and illustrated by the preferred embodiment.

[0091] (1) Setting of mechanical switch:

[0092] A mechanical switch, such as a micro switch, a limit switch, etc., is arranged inside the flip beam 31. The mechanical switch 211 is directly triggered by the movement of the flip beam 31, without the need for electricity or complex control logic. The installation position should ensure that the switch can be reliably popped up when the flip beam 31 is flipped open, thereby disconnecting the control loop 212.

[0093] (2) Implementation of security logic:

[0094] When the flip beam 31 begins to flip open, the contacts of the mechanical switch 211 separate due to the movement of the flip beam 31, causing the control circuit 212 connected to the mechanical switch 211 to be disconnected. The control circuit 212 sends a second detection signal to the main control unit 22, causing the main control unit 22 to control the heating unit 23 to immediately stop heating the flip beam 31.

[0095] When the flip beam 31 returns to its safe position, the mechanical switch 211 is pressed again, closing the control loop 212. At this time, the main control unit 22 receives the first detection signal from the control loop 212; at this time, the main control unit 22 will not start heating immediately, but first check whether other safety conditions are met: the main control unit 22 will check the status of all door switches, and after ensuring that the door is completely closed and locked, the main control unit 22 controls the heating unit 23 to start heating the flip beam 31.

[0096] (3) Fault handling mechanism:

[0097] If at any time the main control unit 22 detects a situation that does not meet safety conditions (such as the flip beam 31 is not in the normal position or the door is not closed), the main control unit 22 will immediately stop heating the flip beam 31 and trigger an alarm or fault indicator light to notify the operator to perform inspection and maintenance.

[0098] In this preferred embodiment, a mechanical switch is used to realize automatic power-off protection when the flip beam 31 is in a dangerous position, and a heating recovery mechanism based on multiple safety conditions is used to improve the safety and reliability of the equipment.

[0099] It should be noted that the steps shown in the above process or the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0103] The heating module 92 is turned off to control the heating unit 23 to stop heating when the detection signal is the second detection signal.

[0104] The heating module 93 is turned on to control the heating unit 23 to start heating when the detection signal is the first detection signal.
