Description
Technical Field
[0001] The utility model relates to the technical field of refrigeration control, in particular to a pressure sensor controlled refrigeration device. Background Art
[0002] At present, domestic refrigerators generally only use temperature sensors to control the temperature. However, in actual use, the contents of items placed in different storage boxes are often different, and the refrigerator is refrigerated under the feedback of the temperature sensor. This will cause the refrigeration effects in storage boxes with different contents of items to be different. The refrigeration effect of the storage box with a large content of items is poor, while the refrigeration effect of the storage box with a small content of items is better. It is impossible to ensure that the items in the storage box with a large content of items remain fresh. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a pressure sensor controlled refrigeration device, which is installed at the bottom of a storage box in a refrigerator. When items with different contents are placed in the storage box, the items with different contents will trigger a signal receiving chip to feed back different signals to the refrigerator refrigeration control unit. The greater the content and the greater the weight of the same items, the better the refrigeration effect.
[0004] In order to solve the above technical problems, the technical solution of the utility model is implemented as follows:
[0005] A pressure sensor controlled refrigeration device comprises a main shell, a signal receiving chip for transmitting refrigeration signals is installed in the main shell; a signal trigger chamber located above the signal receiving chip is opened in the main shell, a gravity sensor seat is arranged on the top of the main shell, a circular array below the gravity sensor seat has multiple pillars that slide through the signal trigger chamber, and each pillar is sleeved with a support spring that pushes the gravity sensor seat to move upward;
[0006] A trigger column is fixed at the center of the lower part of the gravity sensor seat, and a first pressing seat and a second pressing seat located in the signal trigger chamber are respectively fixed on both sides of the lower end of the trigger column;
[0007] A guide column 1 is fixed in the signal trigger chamber, close to the lower pressure seat 1 and arranged parallel to the trigger column. A trigger seat 1 and a return spring 1 for pushing the trigger seat 1 to move upward are mounted on the guide column 1. A blocking seat 1 for blocking the movement of the trigger seat 1 is also fixed on the guide column 1. Conductors 1 located on the same straight line are respectively fixed on the opposite surfaces of the lower pressure seat 1 and the trigger seat 1. The signal receiving chip is electrically connected to the two conductors 1 respectively through two lines.
[0008] A second guide post is fixed in the signal trigger chamber, which is close to the second lower pressure seat and parallel to the trigger post. The second guide post is sleeved with the second trigger seat and the second reset spring for pushing the second trigger seat to move upward. The second guide post is also fixed with a second blocking seat for blocking the movement of the second trigger seat. Two conductors located on the same straight line are respectively fixed on the opposite surfaces of the second lower pressure seat and the second trigger seat. The signal receiving chip is also electrically connected to the two conductors through two lines.
[0009] The pressure sensor-based refrigeration control device is installed at the bottom of the refrigerator storage box, the gravity sensor seat is fixedly connected to the bottom of the refrigerator storage box, and a signal converter is provided on the outside of the main shell. The signal receiving chip and the refrigerator refrigeration control unit are connected through the signal converter to realize signal feedback.
[0010] By adopting the above scheme, the refrigeration control device is installed at the bottom of the storage box in the refrigerator. When items with different contents are placed in the storage box, the items with different contents will trigger the signal receiving chip to feedback different signals to the refrigerator refrigeration control unit. The greater the content of the same items, the greater their weight, which will simultaneously trigger the closure of conductor one on trigger seat one and conductor two on trigger seat two, and the trigger signal receiving chip will feedback to the refrigerator refrigeration control unit to provide a larger amount of cold air outlet, and the refrigeration effect is stronger; on the contrary, the less the content of the same items, the smaller their weight, which will only trigger the closure of conductor one on trigger seat one, and the trigger signal receiving chip will feedback to the refrigerator refrigeration control unit to provide a smaller amount of cold air outlet, and the refrigeration effect is weaker.
[0011] As a preferred implementation method of a pressure sensor controlling a refrigeration device, when a reset spring pushes a conductor to contact a blocking seat, the two conductors between the lower pressure seat and the trigger seat do not touch each other; when a refrigerator storage box is fixed above the gravity sensor seat, all the supporting springs below the gravity sensor seat do not deform.
[0012] By adopting the above scheme, in order to better control energy consumption, when there is no item placed in the refrigerator storage box, the two conductors between the lower pressure seat 1 and the trigger seat 1 do not contact each other. At this time, the two lines of the trigger signal receiving chip cannot form a closed loop. At this time, the trigger signal receiving chip cannot send a feedback signal to the refrigerator refrigeration control unit.
[0013] As a preferred implementation of a pressure sensor controlling a refrigeration device, an anti-deviation shaft one parallel to the guide column one is fixed to one side thereof, and one end of the trigger seat one is also slidably connected to the anti-deviation shaft one.
[0014] By adopting the above scheme, in order to ensure that the trigger seat 1 can move vertically up and down, the anti-axis deviation 1 can effectively prevent the trigger seat 1 from "deflecting" when moving up and down.
[0015] As a preferred implementation of a pressure sensor controlled refrigeration device, a wiring opening is provided through the bottom of the signal trigger chamber, and the wiring connected to the conductor between the lower pressure seat and the trigger seat is centrally confined within the wiring opening.
[0016] By adopting the above solution, in order to avoid the disorder of the line, the line connected to the conductor 1 is led through a bundle opening, thereby realizing the constraint of the line.
[0017] As a preferred implementation of a pressure sensor controlling a refrigeration device, the height of the second blocking seat is lower than the height of the first blocking seat.
[0018] By adopting the above scheme, in order to control the air volume of cold air, when the content of items is small, the weight is light, which will only cause the trigger seat 1 to move, and the controlled air volume is small at this time; but as the content of items increases, the weight becomes heavier until it causes the trigger seat 2 to move, and the controlled air volume is larger at this time.
[0019] As a preferred implementation of a pressure sensor controlling a refrigeration device, a second anti-deviation shaft parallel to the second guide column is fixed to one side thereof, and one end of the second trigger seat is slidably connected to the second anti-deviation shaft.
[0020] By adopting the above solution, in order to ensure that the trigger seat 2 can move vertically up and down, the anti-deflection shaft 2 can effectively prevent the trigger seat 2 from "deflecting" when moving up and down.
[0021] As a preferred implementation of a pressure sensor controlled refrigeration device, a second harness opening is provided through the bottom of the signal trigger chamber, and the circuit connected to the second conductor between the second lower pressure seat and the second trigger seat is centrally confined within the second harness opening.
[0022] By adopting the above solution, in order to avoid the disorder of the line, the line connecting the second conductor is led through the second bundle opening, thereby realizing the constraint of the line.
[0023] After adopting the above technical solution, the beneficial effects of the utility model are:
[0024] 1. The refrigeration control device is installed at the bottom of the storage box in the refrigerator. When different contents of items are placed in the storage box, the items with different contents will trigger the signal receiving chip to feedback different signals to the refrigerator refrigeration control unit. The greater the content of the same items, the greater their weight, which will simultaneously trigger the closure of the conductor 1 on the trigger seat 1 and the conductor 2 on the trigger seat 2. The trigger signal receiving chip will feedback to the refrigerator refrigeration control unit to provide more cold air output, and the refrigeration effect is stronger. On the contrary, the less the content of the same items, the smaller their weight, which can only trigger the closure of the conductor 1 on the trigger seat 1, and the trigger signal receiving chip will feedback to the refrigerator refrigeration control unit to provide a smaller cold air output, and the refrigeration effect is weaker.
[0025] 2. In order to better control energy consumption, when there is nothing in the refrigerator storage box, the two conductors between the lower pressing seat 1 and the trigger seat 1 do not contact each other. At this time, the two lines of the trigger signal receiving chip cannot form a closed loop, and the trigger signal receiving chip cannot send a feedback signal to the refrigerator refrigeration control unit.
[0026] 3. In order to ensure that both the trigger seat 1 and the trigger seat 2 can move vertically up and down, the anti-deflection axis 1 can effectively prevent the trigger seat 1 from "deflecting" when it moves up and down, and the anti-deflection axis 2 can effectively prevent the trigger seat 2 from "deflecting" when it moves up and down;
[0027] 4. In order to avoid the disorder of the lines, the line connected to the conductor one is led through the first wire bundle opening, and the line connected to the conductor two is led through the second wire bundle opening, so as to realize the constraint of the lines.

DETAILED DESCRIPTION
[0041] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0042] like Figures 1 to 11 As shown, a pressure sensor controlled refrigeration device comprises a main housing 1, in which a signal receiving chip 2 for transmitting a refrigeration signal is installed, wherein the signal receiving chip 2 is a single chip microcomputer; a signal trigger chamber 3 located above the signal receiving chip 2 is opened in the main housing 1, a gravity sensor seat 4 is arranged on the top of the main housing 1, and a plurality of pillars 5 are provided in a circular array below the gravity sensor seat 4 and are slidably penetrated into the signal trigger chamber 3, and each pillar 5 is sleeved with a support spring 6 for pushing the gravity sensor seat 4 to move upward;
[0043] A trigger column 7 is fixed at the center of the lower part of the gravity sensor seat 4, and a lower pressure seat 1 8 and a lower pressure seat 2 16 located in the signal trigger chamber 3 are respectively fixed on both sides of the lower end of the trigger column 7;
[0044] A guide column 9 is fixed in the signal trigger chamber 3, which is close to the lower pressure seat 8 and parallel to the trigger column 7. A trigger seat 10 and a return spring 12 for pushing the trigger seat 10 to move upward are mounted on the guide column 9. A blocking seat 11 for blocking the movement of the trigger seat 10 is also fixed on the guide column 9. Conductors 13 located on the same straight line are respectively fixed on the opposite surfaces of the lower pressure seat 8 and the trigger seat 10. The signal receiving chip 2 is electrically connected to the two conductors 13 through two lines.
[0045] A guide column 2 17 is fixed in the signal trigger chamber 3, which is close to the lower pressure seat 2 16 and parallel to the trigger column 7. A trigger seat 2 18 and a reset spring 20 for pushing the trigger seat 2 18 to move upward are mounted on the guide column 17. A blocking seat 2 19 for blocking the movement of the trigger seat 2 18 is also fixed on the guide column 17. Two conductors 21 located on the same straight line are respectively fixed on the opposite surfaces of the lower pressure seat 2 16 and the trigger seat 2 18. The signal receiving chip 2 is also electrically connected to the two conductors 21 through two lines.
[0046] The pressure sensor-based refrigeration control device is installed at the bottom of the refrigerator storage box 25, the gravity sensor seat 4 is fixedly connected to the bottom of the refrigerator storage box 25, and a signal converter 24 is provided on the outside of the main shell 1. The signal receiving chip 2 and the refrigerator refrigeration control unit are connected through the signal converter 24 to realize signal feedback.
[0047] The refrigeration control device is installed at the bottom of the storage box in the refrigerator. When items of different contents are placed in the storage box, the items of different contents will trigger the signal receiving chip 2 to feed back different signals to the refrigerator refrigeration control unit. The greater the content of the same items, the greater their weight, which will simultaneously trigger the conductor 13 on the trigger seat 10 and the conductor 21 on the trigger seat 2 18 to close, and the trigger signal receiving chip 2 will feed back to the refrigerator refrigeration control unit to provide a larger amount of cold air outlet, and its refrigeration effect is stronger; on the contrary, the less the content of the same items, the smaller their weight, which will only trigger the conductor 13 on the trigger seat 10 to close, and the trigger signal receiving chip 2 will feed back to the refrigerator refrigeration control unit to provide a smaller amount of cold air outlet, and its refrigeration effect is weaker.
[0048] like Figure 6 to Figure 7As shown, when the reset spring 12 pushes the conductor 13 to contact the blocking seat 11, the two conductors 13 between the lower pressing seat 8 and the trigger seat 10 just do not touch each other; when the refrigerator storage box 25 is fixed on the gravity sensor seat 4, all the support springs 6 under the gravity sensor seat 4 just do not deform. In order to better control energy consumption, when the refrigerator storage box 25 does not place any items, the two conductors 13 between the lower pressing seat 8 and the trigger seat 10 do not touch each other, and the two lines of the trigger signal receiving chip 2 cannot form a closed loop. At this time, the trigger signal receiving chip 2 cannot send a feedback signal to the refrigerator refrigeration control unit.
[0049] like Figure 7 As shown, a guide column 9 is also fixed with an anti-deflection shaft 14 parallel to the guide column 9, and one end of the trigger seat 10 is also slidably connected to the anti-deflection shaft 14. In order to ensure that the trigger seat 10 can move vertically up and down, the anti-deflection shaft 14 can effectively prevent the trigger seat 10 from "deflecting" when moving up and down.
[0050] like Figure 7 As shown, a cable tie port 15 is provided through the bottom of the signal trigger chamber 3, and the lines connected to the conductor 13 between the lower pressing seat 8 and the trigger seat 10 are centrally restrained in the cable tie port 15. In order to avoid the lines being messy, the lines connected to the conductor 13 are led through the cable tie port 15, thereby realizing the restraint of the lines.
[0051] like Figure 7 As shown, the height of the blocking seat 2 19 is lower than that of the blocking seat 1 11. In order to control the air volume of the cold air, when the content of the items is small, the weight is light, and only the trigger seat 10 is triggered to move, and the controlled air volume is small at this time; but as the content of the items increases, the weight becomes heavier until the trigger seat 2 18 is triggered to move, and the controlled air volume is large at this time.
[0052] like Fig. 9 As shown, a second anti-deflection shaft 22 parallel to the guide column 17 is fixed to one side, and one end of the trigger seat 18 is also slidably connected to the second anti-deflection shaft 22. In order to ensure that the trigger seat 18 can move vertically up and down, the second anti-deflection shaft 22 can effectively prevent the trigger seat 18 from "deflecting" when moving up and down.
[0053] like Fig. 9 As shown, a second cable opening 23 is provided through the bottom of the signal trigger chamber 3, and the lines connected to the second conductor 21 between the second lower pressing seat 16 and the second trigger seat 18 are centrally constrained in the second cable opening 23. In order to avoid the lines being messy, the lines connected to the second conductor 21 are led through the second cable opening 23, thereby realizing the constraint of the lines.
[0054] The working principle of this utility model:
[0055] During use, when fewer items are placed in the refrigerator storage box 25, the support spring 6 is compressed, the trigger column 7 moves downward, and the trigger seat 10 is pressed downward by the lower pressure seat 8. At this time, the two conductors 13 between the lower pressure seat 8 and the trigger seat 10 are in contact with each other, and the line connecting the two conductors 13 between the lower pressure seat 8 and the trigger seat 10 forms a closed loop, and then the trigger signal receiving chip 2 feeds back to the refrigerator refrigeration control unit to provide a smaller cold air output volume, and its refrigeration effect is weak, which is just right for a small amount of items.
[0056] As more items continue to be placed in the refrigerator storage box 25, the support spring 6 continues to be compressed, and the trigger column 7 moves downward. At the same time, the trigger seat 18 is pressed downward by the lower pressure seat 16. At this time, the two conductors 21 between the lower pressure seat 16 and the trigger seat 18 are in contact with each other, and the line connecting the two conductors 21 between the lower pressure seat 16 and the trigger seat 18 forms a closed loop. Then the trigger signal receiving chip 2 provides more cold air output to the refrigerator refrigeration control unit, and the refrigeration effect is stronger to meet the refrigeration needs of more items.
[0057] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
