A temperature controller with a probe

Abstract

This utility model relates to the field of thermostat technology and discloses a thermostat with a probe, comprising: a base plate, a first mounting hole at the front of the top of the base plate, and a fixing block movably connected to the front end of the top of the base plate. This thermostat with a probe, due to the vacuum state of the cavity between the fixing block and the inner liner, possesses excellent heat insulation performance. Its near-vacuum environment effectively blocks the conduction path of radiant heat from the heating element, thus creating a highly efficient heat insulation barrier for the temperature sensor. Compared with traditional structures, under the same heating conditions, the influence of the heating element on the temperature sensor is significantly reduced, allowing the temperature sensor to accurately capture the true water temperature inside the kettle, and stably control the deviation between the detected temperature and the actual water temperature within a very small range, greatly improving the accuracy of temperature monitoring. Furthermore, due to the spring design, the top of the probe can be kept in contact with the bottom of the heating plate to ensure the stability of probe monitoring.

Description

Technical Field

[0001] This utility model relates to the field of temperature controller technology, and more specifically, to a temperature controller with a probe. Background Technology

[0002] In daily life, electric kettles have become essential small household appliances due to their convenience and efficiency. The thermostat with a probe is a core component of electric kettles, enabling precise temperature control and ensuring safe use; its performance directly affects product quality.

[0003] Currently, most electric kettles use temperature sensor installation structures with significant flaws. A common design involves mounting the sensor at the bottom of the heating element and connecting it to the thermostat via a lead wire. This results in the sensor being positioned far from the center of the heating element and too close to the heating element itself. When the heating element is powered on, the resulting radiant heat directly affects the sensor. Due to interference from this radiant heat, the sensor's detected temperature deviates significantly from the actual temperature, causing the thermostat to prematurely trigger its power-off protection, preventing the kettle from boiling the water. Therefore, improvements are needed. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 6 As shown, this utility model provides a temperature controller with a probe, comprising:

[0027] The base plate 1 has a first assembly hole 2 at the front of the top of the base plate 1. A fixing block 3 is movably connected to the front end of the top of the base plate 1. An air extraction port 6 is fixedly sleeved on the front end of the fixing block 3. A first assembly groove 4 is opened on the fixing block 3. A first screw 5 is sleeved in the internal thread of the first assembly groove 4. The bottom end of the outer surface of the first screw 5 is sleeved with the internal thread of the first assembly hole 2.

[0028] The heat insulation mechanism is disposed inside the fixed block 3;

[0029] The heat insulation mechanism includes an inner liner 7, the outer surface of which is fixedly sleeved with the inside of the fixing block 3, a probe 8 is movably sleeved inside the inner liner 7, a fixing ring 9 is fixedly sleeved on the outer surface of the probe 8, and a spring 10 is fixedly installed at the top of the fixing ring 9, with the top of the spring 10 fixedly connected to the inside of the inner liner 7.

[0030] Due to the design of the first assembly hole 2 and the first assembly groove 4, the base plate 1 and the fixing block 3 can be easily assembled by the first screw 5. Due to the design of the air extraction port 6, the operator can extract the air between the inner liner 7 and the fixing block 3 through the air extraction port 6, so that the cavity between the inner liner 7 and the fixing block 3 is in a near-vacuum state, thereby preventing the probe 8 from being affected by the external environment. Since the probe 8 is in a movable sleeve with the inner liner 7, the probe 8 can move downward along the inside of the inner liner 7. At this time, the probe 8 will stretch the spring 10 through the fixing ring 9.

[0031] The base plate 1 has a second mounting hole 11 at its top end, and a thermostat body 12 is movably connected to the top end of the base plate 1. The thermostat body 12 has a second mounting groove 13 at its top end, and a second screw 14 is threaded into the inner thread of the second mounting groove 13. The bottom end of the outer surface of the second screw 14 is threaded into the inner thread of the second mounting hole 11.

[0032] When the thermostat body 12 is placed on the top of the base plate 1 and the second mounting groove 13 is aligned with the inside of the second mounting hole 11, the operator can then assemble the thermostat body 12 with the base plate 1 by screwing the second screw 14 into the inside of the second mounting groove 13 and the second mounting hole 11.

[0033] The thermostat body 12 has a third mounting hole 16 on its outer surface. A third screw 17 is threaded into the inner surface of the third mounting hole 16. A connecting block 18 is threaded into the outer surface of the third screw 17. A heating plate 19 is fixedly installed on the top of the connecting block 18. The bottom of the heating plate 19 is in contact with the outer surface of the thermostat body 12. The interior of the heating plate 19 is movably connected to the outer surface of the thermostat body 12.

[0034] When the bottom of the heating plate 19 is in contact with the thermostat body 12, the inside of the connecting block 18 will be aligned with the third mounting hole 16. At this time, the operator can screw the third screw 17 into the third mounting hole 16 and the inside of the connecting block 18 to complete the assembly of the thermostat body 12 and the fixing ring 9.

[0035] The bottom end of the heating plate 19 is attached to the top end of the fixing block 3, and the bottom end of the heating plate 19 abuts against the top end of the probe 8.

[0036] When the bottom of the heating plate 19 is in contact with the thermostat body 12, the bottom of the heating plate 19 will press and push the top of the probe 8, causing the probe 8 to move downward along the inside of the inner liner 7. Due to the elastic force of the spring 10, the top of the probe 8 will always remain in contact with the bottom of the heating plate 19.

[0037] The heating element 15 is fixedly installed at the bottom of the heating plate 19, and the heating element 15 is located on the periphery of the thermostat body 12.

[0038] When the heating element 15 is running, it will generate heat, and at this time the heating element 15 will heat the water in the kettle through the heating plate 19.

[0039] Among them, an arc-shaped block 20 is fixedly installed on the outer surface of the fixing block 3. A fourth assembly hole 21 is opened on the arc-shaped block 20. A positioning block 22 is movably connected to the top of the arc-shaped block 20. The top of the positioning block 22 is fixedly connected to the bottom of the heating plate 19. The interior of the positioning block 22 is movably sleeved with the outer surface of the fixing block 3. A third assembly groove 23 is opened at the bottom of the positioning block 22. A fourth screw 24 is threadedly sleeved inside the third assembly groove 23. The outer surface of the fourth screw 24 is threadedly sleeved with the interior of the fourth assembly hole 21.

[0040] When the bottom of the heating plate 19 is in contact with the top of the fixing block 3, the inside of the positioning block 22 will be fitted onto the outer surface of the fixing block 3. Due to the design of the positioning block 22, it will play a good positioning role in the connection between the fixing block 3 and the heating plate 19. At this time, the inside of the fourth assembly hole 21 and the third assembly groove 23 will be aligned. At this time, the operator can screw the fourth screw 24 into the inside of the fourth assembly hole 21 and the fourth screw 24 to complete the assembly of the fixing block 3 and the heating plate 19.

[0041] The bottom end of the heating plate 19 is fixedly installed with a gasket 25, and the bottom end of the gasket 25 is in contact with the top end of the inner liner 7.

[0042] The design of the gasket 25 will increase the sealing of the overall connection between the heating plate 19 and the fixing block 3.

[0043] Working principle and usage process of this utility model:

[0044] First, the operator places the thermostat body 12 on the top of the base plate 1, aligning the inside of the second mounting groove 13 with the inside of the second mounting hole 11. Then, the operator screws the second screw 14 into the second mounting hole 11 from the inside of the second mounting groove 13, completing the assembly between the thermostat body 12 and the base plate 1. Next, the operator places the fixing block 3 on the front side of the top of the base plate 1, aligning the inside of the first mounting groove 4 with the inside of the first mounting hole 2. Then, the operator screws the first screw 5 into the first mounting hole 2 from the inside of the first mounting groove 4, completing the assembly between the base plate 1 and the fixing block 3. Immediately afterward, the operator fits the heating plate 19 onto the outer surface of the thermostat body 12. During this process, the operator... The operator needs to align the inside of the third assembly hole 16 with the inside of the heating plate 19. When the bottom of the heating plate 19 is in contact with the outer surface of the thermostat body 12, the positioning block 22 will be sleeved on the outer surface of the fixing block 3. Due to the design of the positioning block 22, it will play a good positioning role in the connection between the fixing block 3 and the heating plate 19. At this time, the operator will screw the third screw 17 into the inside of the heating plate 19 through the inside of the third assembly hole 16, so that the thermostat body 12 and the heating plate 19 are assembled together. Then, the operator will screw the fourth screw 24 into the inside of the third assembly slot 23 through the inside of the fourth assembly hole 21, so that the fixing block 3 and the heating plate 19 are assembled together, thereby realizing the function of conveniently assembling various components.

[0045] During the assembly of the heating plate 19 and the fixing block 3, the bottom of the heating plate 19 will press and push the top of the probe 8, causing the probe 8 to move downward along the inside of the inner liner 7. At this time, the fixing ring 9 will move downward under the drive of the probe 8. During this process, the spring 10 will be stretched. Due to the elastic force of the spring 10, the top of the probe 8 will always be in contact with the bottom of the heating plate 19, thereby ensuring that the probe 8 can stably monitor the temperature of the heating plate 19. When the bottom of the heating plate 19 contacts the top of the fixing block 3, the bottom of the gasket 25 will contact the top of the inner liner 7. Due to the design of the gasket 25, the tightness of the connection between the heating plate 19 and the fixing block 3 will be enhanced. After the heating plate 19 and the fixing block 3 are connected, the operator will extract the air between the fixing block 3 and the inner liner 7 through the air extraction port 6, so that the cavity between the fixing block 3 and the inner liner 7 is in a vacuum state, thereby preventing the heating tube 15 from affecting the probe 8 when it heats up.
