Description

Technical Field

[0001] The present invention relates to the technical field of temperature controllers, and in particular to a protective temperature controller. Background Art

[0002] A thermostat is an automatic control element that controls the conduction or disconnection of a circuit according to the temperature changes in the working environment. There are two types of thermostats: integrated and split. The split thermostat relies on a wire to connect to a temperature sensor installed in the working environment during use, and controls the on and off of the circuit by reading the signal from the temperature sensor. The integrated thermostat monitors the temperature changes in the working environment through the temperature sensor contained inside it, and controls the on and off of the circuit through the physical deformation inside it. Of the above two types of thermostats, the integrated thermostat is widely used due to its advantages of easy and flexible installation, stable signal transmission, and fast response speed.

[0003] In the field of food storage, thermostats are usually installed inside cold storage to accurately control the temperature inside the cold storage. However, due to the high humidity in the air in the cold storage, in order to prevent moisture from damaging the electrical components inside the thermostat, the thermostat is usually set to a completely sealed state. Although this can prevent moisture from damaging the electrical components, when the temperature of the cold storage changes, the heat in the cold storage is first exchanged with the outer casing of the thermostat, and then the heat is transferred to the temperature sensor through the outer casing of the thermostat and the air inside the outer casing. This causes the temperature change in the thermostat to be delayed relative to the temperature change in the cold storage, making it impossible for the thermostat to respond to the temperature change in the cold storage in time, resulting in large temperature fluctuations in the cold storage, which will affect some storage items in the cold storage that require high temperature accuracy. Summary of the invention

[0040] In the above scheme, it is intended to solve the problem that when the existing thermostat is used in a cold storage, due to the thermostat being in a completely sealed state, there is a delay when the temperature sensor in the thermostat senses the temperature in the cold storage, so that the thermostat cannot respond to the temperature change in the cold storage in time, resulting in large temperature fluctuations in the cold storage; this scheme utilizes the rotation of the heat-conducting ring 9 to shorten the distance for heat exchange between the monitoring module 5 and the heat-conducting ring 9, thereby shortening the time for the heat from the cold storage to be transferred to the monitoring module 5, improving the response speed of the monitoring module 5, thereby reducing the temperature fluctuation amplitude in the cold storage, and facilitating the preservation of items in the cold storage; the air in the cold storage enters the shell 1 through the connecting notch 101; the rear side of the terminal cover 3 is provided with a terminal electrically connected to the outside world; the shell 1, the display end cover 2, the partition 4, the mounting plate 7 and the supporting arc block 8 together constitute a monitoring chamber, the monitoring module 5 is located in the monitoring chamber composed of the shell 1, the display end cover 2, the partition 4, the mounting plate 7 and the supporting arc block 8, with the position of the mounting plate 7 as the dividing line, the upper half of the heat-conducting ring 9 is located in the monitoring chamber, and the lower half of the heat-conducting ring 9 is in contact with the gas in the cold storage through the connecting notch 101; the material of the heat-conducting ring 9 can be copper, and the heat-conducting ring 9 is composed of two halves (the specific connection state between the two halves of the heat-conducting ring 9 is not shown in the figure), and the two halves of the heat-conducting ring 9 can be connected by mortise and tenon or snap-fit; the partition 4 can be made of phenolic foam or aerogel material, which is used to separate the power module 6 from the monitoring module 5, reduce the influence of the heat generated during the operation of the power module 6 on the temperature near the monitoring module 5, and thereby improve the accuracy of the monitoring module 5 in detecting the temperature in the cold storage.

[0041] A mounting ring 201 can be slidably connected to the shell 1, and the mounting ring 201 is connected to the shell 1 by a snap-fit ​​connection for installing the shell 1. The steps for installing the device to the cold storage temperature control cabinet are as follows: slide the mounting ring 201 backward until it is separated from the shell 1, then insert the shell 1 into the hole reserved on the temperature control cabinet, and reinstall the mounting ring 201 on the shell 1 so that the two are snap-fitted. At this time, the mounting ring 201 and the display end cover 2 are respectively attached to the two sides of the hole reserved in the temperature control cabinet, and the installation of the device is completed; the monitoring module 5 passes through the display end cover 2 and is fixed with an adjustment knob 501. The staff can adjust the monitoring module 5 by turning the adjustment knob 501, so that the monitoring module 5 disconnects or connects the circuit at a specified temperature (the temperature when the monitoring module 5 controls the circuit to be disconnected and connected is referred to as the trigger temperature later); when the device is applied to a cold storage, the monitoring module 5 is connected to the control circuit of the refrigerator to control the on and off of the refrigerator circuit.

[0042] Please refer to Figure 3-Figure 7 The power assembly includes: a motor 10, which is installed in the housing 1. The output shaft of the motor 10 is fixedly connected to a gear 11. The support arc block 8 is slidably connected to a power arc block 12. The power arc block 12 passes through the mounting plate 7. The power arc block 12 is fixedly connected to a rack 13 meshing with the gear 11; a dynamic seal 14, which is fixedly connected to the power arc block 12 on one side close to the communicating notch 101. The heat conductive ring 9 passes through the dynamic seal 14. The heat conductive ring 9 is sealingly and slidably connected to a first sealing ring 15. The first sealing ring 15 is located in the dynamic seal 14 and contacts the dynamic seal 14; a static seal 16, which is fixedly connected to the side of the mounting plate 7 close to the dynamic seal 14. The heat conductive ring 9 passes through the static seal 16. The heat conductive ring 9 is sealingly and slidably connected to a second sealing ring 17. The second sealing ring 17 is located in the static seal 16 and in contact with the static seal 16, two supporting bevels 161 and two extrusion bevels 162 are arranged in the dynamic seal 14 and the static seal 16, the minimum distance between the extrusion bevel 162 and the heat-conducting ring 9 is smaller than the diameter of the cross section of the first sealing ring 15 and the second sealing ring 17, the first sealing ring 15 and the second sealing ring 17 are respectively squeezed by the adjacent supporting bevels 161 and the adjacent extrusion bevels 162; the minimum distance between the supporting bevel 161 and the heat-conducting ring 9 is smaller than the radius of the cross section of the first sealing ring 15 and the second sealing ring 17; the central axis of the heat-conducting ring 9 is not on the plane where the supporting bevel 161 is located; and also includes: an accordion protective cover 18, which is fixed between the dynamic seal 14 and the static seal 16, and the heat-conducting ring 9 passes through the accordion protective cover 18.

[0043] In the above scheme, the reciprocating movement of the power arc block 12 is used to drive the heat-conducting ring 9 to rotate in one direction; the projection of the rack 13 on the end face of the heat-conducting ring 9 has a central angle of 160° with the center of the end face of the heat-conducting ring 9 as the center of the circle, so that after the power arc block 12 reciprocates for one cycle, the lower half of the heat-conducting ring 9 rotates to the upper side of the mounting plate 7 and can wrap the monitoring module 5, and transfer the external heat to the monitoring chamber through the heat-conducting ring 9; the dynamic seal 14 and the static seal 16 have the same structure, and both of them are composed of a U-shaped portion and a cover plate (refer to Figure 7 ), the U-shaped parts of the dynamic seal 14 and the static seal 16 can be connected to the cover plate by snaps or screws, and the front and rear positions of the second sealing ring 17 are always in contact with the static seal 16 and the heat-conducting ring 9; the first sealing ring 15 and the second sealing ring 17 are both rectangular rubber rings made of elastic rubber material, and the first sealing ring 15 and the second sealing ring 17 are both in contact with the heat-conducting ring 9, that is, there is friction between the heat-conducting ring 9 and the first sealing ring 15 and the second sealing ring 17.

[0044] The central axis of the heat-conducting ring 9 is not on the plane where the supporting bevel 161 is located (the second sealing ring 17 and the adjacent supporting bevel 161 will be used as an example to explain later). When the second sealing ring 17 contacts the adjacent supporting bevel 161, the component force of the supporting force of the supporting bevel 161 on the second sealing ring 17 is toward the normal direction of the supporting bevel 161, and there is a tendency to "expand outward" the second sealing ring 17, thereby reducing the squeezing force of the second sealing ring 17 on the heat-conducting ring 9 when the second sealing ring 17 contacts the supporting bevel 161. On the one hand, the wear on the second sealing ring 17 caused by the relative movement of the heat-conducting ring 9 and the second sealing ring 17 is reduced, and on the other hand, the probability of the second sealing ring 17 being stuck between the supporting bevel 161 and the heat-conducting ring 9 is reduced.

[0045] The upper side of the mounting plate 7 is rotatably connected to two inner support rollers 19, which are in contact with the inner side of the heat-conducting ring 9. The inner side of the supporting arc block 8 is rotatably connected to an outer support roller 20, which is in contact with the outer side of the heat-conducting ring 9. The inner and outer support rollers 19 and 20 are used to support the inner and outer sides of the heat-conducting ring 9 respectively, so that the rotation process of the heat-conducting ring 9 is smoother.

[0046] The working principle of the above scheme is as follows: when using the device to control the temperature of the cold storage, the staff turns the adjustment knob 501 to set the trigger temperature of the monitoring module 5, and then starts the refrigerator and motor 10 of the cold storage. At this time, the temperature in the cold storage is greater than the trigger temperature, the monitoring module 5 is in a connected state, the refrigerator works and reduces the temperature in the cold storage; because the lower half of the heat conductive ring 9 is directly in contact with the air in the cold storage through the connecting notch 101, heat transfer occurs between the air in the cold storage and the lower half of the heat conductive ring 9, and finally the lower part of the heat conductive ring 9 reaches the same temperature as that in the cold storage; as the output shaft of the motor 10 rotates clockwise and the gear rack 13 moves through the gear 11, the gear rack 13 drives the power arc block 12 to rotate counterclockwise, and the power arc block 12 drives the dynamic seal 14 to move together (the distance between the dynamic seal 14 and the static seal 16 increases, and the accordion protective cover 18 is stretched).

[0047] When the dynamic seal 14 starts to move, the heat-conducting ring 9 is in a stationary state. As the dynamic seal 14 moves, the dynamic seal 14 drives the two adjacent extrusion slopes 162 to gradually contact the first sealing ring 15. At this time, the extrusion slope 162 drives the heat-conducting ring 9 to rotate counterclockwise through the first sealing ring 15 (through the friction between the first sealing ring 15 and the heat-conducting ring 9), and the heat-conducting ring 9 drives the second sealing ring 17 to rotate, so that the second sealing ring 17 contacts the two supporting slopes 161 on the static seal 16. At this time, the second sealing ring 17 is limited by the adjacent supporting slopes 161 and stops moving. The second sealing ring 17 relies on The friction between it and the heat-conducting ring 9 causes the heat-conducting ring 9 and the first sealing ring 15 to stop rotating together. As the dynamic seal 14 continues to rotate circumferentially, the two extrusion slopes 162 on the dynamic seal 14 rotate counterclockwise relative to the first sealing ring 15, causing the first sealing ring 15 to deform. At the same time, the friction between the first sealing ring 15 and the adjacent extrusion slopes 162 gradually increases until the friction is greater than the friction between the second sealing ring 17 and the heat-conducting ring 9. The dynamic seal 14 drives the first sealing ring 15 and the heat-conducting ring 9 to rotate together (relative displacement occurs between the second sealing ring 17 and the heat-conducting ring 9).

[0048] During the counterclockwise rotation of the heat-conducting ring 9, the lower part of the heat-conducting ring 9 gradually rotates to the top of the mounting plate 7, and exchanges heat with the monitoring module 5 through the air in the monitoring chamber, so that the temperature of the monitoring module 5 eventually tends to be consistent with the temperature of the original lower part of the heat-conducting ring 9 (i.e., the temperature in the cold storage). In this way, the temperature in the cold storage is transferred to the monitoring module 5 by the rotation of the heat-conducting ring 9, eliminating the time consumed by the heat in the cold storage passing through the thermostat housing, thereby reducing the delay of the monitoring module 5 sensing the temperature in the cold storage; during the rotation of the heat-conducting ring 9, the upper part of the heat-conducting ring 9 gradually moves out of the monitoring chamber and exchanges heat with the air in the cold storage.

[0049] In the process of gear 11 moving along rack 13, gear 11 gradually moves to the end of rack 13, at this time, motor 10 reverses, the output shaft of motor 10 drives power arc block 12 to rotate clockwise through gear 11 and rack 13, power arc block 12 drives heat conducting ring 9 and second sealing ring 17 to rotate clockwise through first sealing ring 15, so that second sealing ring 17 loses contact with adjacent supporting inclined surface 161, and gradually contacts with adjacent extrusion inclined surface 162, as second sealing ring 17 continues to move, second sealing ring 17 is gradually pressed by adjacent extrusion inclined surface 162. The friction between the second sealing ring 17 and the heat-conducting ring 9 increases gradually due to the extrusion deformation, until the friction is greater than the friction between the first sealing ring 15 and the dynamic seal 14. As the dynamic seal 14 moves, the first sealing ring 15 gradually loses contact with the adjacent extrusion slope 162, and the distance between the first sealing ring 15 and the adjacent supporting slope 161 gradually decreases. Finally, the dynamic seal 14 drives the adjacent supporting slope 161 to contact with the first sealing ring 15, and the first sealing ring 15 moves with the dynamic seal 14 (at this time, the heat-conducting ring 9 and the second sealing ring 17 are in a stationary state).

[0050] During the clockwise axial rotation of the dynamic seal 14, the dynamic seal 14 gradually resets, and at this time the output shaft of the motor 10 rotates clockwise, and drives the power arc block 12 and the dynamic seal 14 to rotate counterclockwise again (at this time, the friction between the first sealing ring 15 and the heat conductive ring 9 makes the first sealing ring 15 temporarily in a static state), so that the first sealing ring 15 loses contact with the adjacent supporting inclined surface 161, and the distance between the first sealing ring 15 and the adjacent extrusion inclined surface 162 gradually decreases, and finally the extrusion inclined surface 162 contacts with the first sealing ring 15 and squeezes the first sealing ring 15 to deform, until the first sealing ring 15 and the heat conductive ring 9 are in contact. When the friction force between the rings 9 is greater than the friction force between the second sealing ring 17 and the static seal 16, the dynamic seal 14 drives the heat-conducting ring 9 and the second sealing ring 17 to rotate circumferentially together through the first sealing ring 15, and finally makes the second sealing ring 17 contact with the adjacent supporting slope 161, and then repeats the above-mentioned steps of rotating the heat-conducting ring 9. The temperature in the cold storage is transferred to the vicinity of the monitoring module 5 through the rotation of the heat-conducting ring 9, so that the monitoring module 5 can sense the temperature in the cold storage. When the temperature in the cold storage drops to the trigger temperature, the monitoring module 5 is deformed and the power supply of the refrigerator is disconnected, and the refrigerator stops working.

[0051] In the process of the heat-conducting ring 9 rotating by the reciprocating movement of the dynamic seal 14, the first sealing ring 15 and the second sealing ring 17 are alternately in contact with the adjacent extrusion slope 162, thereby enhancing the extrusion force of the first sealing ring 15 or the second sealing ring 17 on the heat-conducting ring 9, thereby enhancing the sealing effect of the contact surface between the first sealing ring 15 or the second sealing ring 17 and the heat-conducting ring 9. At the same time, the first sealing ring 15 or the second sealing ring 17 in contact with the extrusion slope 162 and the heat-conducting ring 9 remain relatively still, and the first sealing ring 15 or the second sealing ring 17 in contact with the supporting slope 161 moves relatively with the heat-conducting ring 9. In this way, the first sealing ring 15 or the second sealing ring 17 in contact with the support slope 161 can be used to seal the heat-conducting ring 9. The ring 15 and the second sealing ring 17 seal the gap between the adjacent extrusion inclined surface 162 and the heat-conducting ring 9 alternately, thereby ensuring the sealing effect (when the first sealing ring 15 or the second sealing ring 17 contacts the extrusion inclined surface 162, the first sealing ring 15 or the second sealing ring 17 exerts a large extrusion force on the heat-conducting ring 9), and reducing the wear of the first sealing ring 15 and the second sealing ring 17 when the heat-conducting ring 9 moves relative to the first sealing ring 15 and the second sealing ring 17 (when the first sealing ring 15 or the second sealing ring 17 contacts the supporting inclined surface 161, the first sealing ring 15 or the second sealing ring 17 exerts a small extrusion force on the heat-conducting ring 9).

[0052] Please refer to Figure 3 , Figure 5 , Figure 8 and Fig. 9 , also includes: a cleaning piece 21, which is fixed to one side of the mounting plate 7 close to the communicating notch 101, and two sponge blocks 22 are fixedly connected in the cleaning piece 21, and the two sponge blocks 22 are respectively in contact with the inner and outer sides of the heat-conducting ring 9; two support strips 23, which are both fixed in the cleaning piece 21 and are respectively in contact with adjacent sponge blocks 22; a third sealing ring 24, which is sealingly and slidably connected to the heat-conducting ring 9 and is located in the cleaning piece 21, and the third sealing ring 24 is in contact with the cleaning piece 21; a through hole is provided on the cleaning piece 21, and the lower part of the sponge block 22 passes through the adjacent through hole on the cleaning piece 21, and the through hole on the cleaning piece 21 is used to discharge the moisture in the adjacent sponge block 22; the support strip 23 is made of elastic rubber, and the third sealing ring 24 is in contact with the support strip 23.

[0053] In the above scheme, the purpose is to reduce the amount of water vapor condensed on the heat-conducting ring 9 entering the monitoring chamber as the heat-conducting ring 9 rotates; in this scheme, the heat-conducting ring 9 and the cleaning member 21 are relatively displaced by the rotation of the heat-conducting ring 9, and then the cleaning member 21 is used to scrape off the water droplets condensed on the surface of the heat-conducting ring 9 by the surface contact between the cleaning member 21 and the heat-conducting ring 9, thereby reducing the amount of water vapor in the cold storage entering the monitoring chamber; the lower end of the cleaning member 21 is made of elastic rubber material and is always in contact with the heat-conducting ring 9. The cleaning member 21 is composed of a U-shaped portion and a cover plate. The U-shaped portion of the cleaning piece 21 is connected to the cover plate by means of buckles or screws; the sponge block 22 is a polyurethane sponge, and when it contacts the surface of the heat-conducting ring 9, water droplets are sucked into the sponge block 22 under the action of capillarity; the opposite sides of the two support strips 23 are fixedly connected to the cleaning piece 21, that is, the support strips 23 can swing in the cleaning piece 21; the third sealing ring 24 has the same shape and material as the second sealing ring 17, and there is friction between the third sealing ring 24 and the heat-conducting ring 9, and the friction is greater than the force required to deform the support strips 23.

[0054] The working principle of the above scheme is as follows: when the power arc block 12 drives the heat-conducting ring 9 to rotate counterclockwise, a relative displacement occurs between the heat-conducting ring 9 and the cleaning piece 21, and the lower part of the cleaning piece 21 adheres to the heat-conducting ring 9 and scrapes off the water droplets condensed on the surface of the heat-conducting ring 9. As the heat-conducting ring 9 continues to rotate, the heat-conducting ring 9 contacts the sponge block 22, and the water stains remaining on the heat-conducting ring 9 are absorbed by the sponge block 22, thereby reducing the probability of the heat-conducting ring 9 rotating and bringing the water vapor in the cold storage into the monitoring chamber. When the water volume in the sponge block 22 is large, the water in the sponge block 22 flows downward under the action of its own gravity until it passes through the position of the sponge block 22 at the through hole on the cleaning piece 21 and then drips; during the counterclockwise rotation of the heat-conducting ring 9, it drives the third sealing ring 24 to squeeze the cleaning piece 21, thereby increasing the contact area between the cleaning piece 21 and the third sealing ring 24, and enhancing the sealing performance.

[0055] When the power arc block 12 rotates clockwise, the above steps of clockwise rotation of the power arc block 12 are repeated. The power arc block 12 first drives the heat conductive ring 9 to rotate clockwise by a certain angle, and then the heat conductive ring 9 remains stationary. When the heat conductive ring 9 rotates clockwise, the heat conductive ring 9 drives the third sealing ring 24 to rotate clockwise. The third sealing ring 24 squeezes the two support bars 23 and makes the two support bars 23 swing. The support bars 23 squeeze the adjacent sponge blocks 22, so that the water accumulated in the sponge blocks 22 flows out from the sponge blocks 22, thereby preventing the water content in the sponge blocks 22 from affecting the absorption of water stains on the heat conductive ring 9.

[0056] Please refer to Figure 4 and Fig.10 The monitoring module 5 is fixedly connected with a T-shaped piece 25 , and the T-shaped piece 25 is in contact with the heat-conducting ring 9 . The T-shaped piece 25 is made of a material with good thermal conductivity but no electrical conductivity.

[0057] In the above scheme, it is intended to solve the problem that when the existing thermostat is in a completely sealed state, the temperature sensor in the thermostat relies on the thermostat shell and the air inside it to exchange heat with the outside world, resulting in low heat exchange efficiency, causing the temperature sensor to sense the outside temperature with a delay; this scheme uses the T-shaped piece 25 to provide a medium for heat exchange between the thermally conductive ring 9 and the monitoring module 5, thereby improving the efficiency of heat exchange between the monitoring module 5 and the outside world and enhancing the real-time performance of the monitoring module 5 in sensing the outside temperature; the T-shaped piece 25 can be made of aluminum nitride, which has excellent thermal conductivity and insulation properties, and can transfer the heat on the thermally conductive ring 9 to the monitoring module 5 without electrically connecting the monitoring module 5 to the thermally conductive ring 9, thereby reducing the probability of electric shock to the staff and improving the practicality of the device.
