Description

Technical Field

[0001] The utility model relates to the technical field of liquid heaters, in particular to a double temperature sensor control structure of a full-glass liquid heater. Background Art

[0002] Currently, liquid heaters equipped with glass cups on the market generally use a combination of a single temperature sensor + a capacitive liquid level sensor to achieve temperature detection and temperature control to avoid dry burning. However, the current temperature detection structure has the disadvantage of being prone to misjudgment, especially when there is steam in the glass cup. Therefore, there is a greater risk.

[0003] Therefore, it is necessary to improve the prior art. Utility Model Content

[0004] The present invention aims to solve at least one of the problems existing in the existing related technologies to a certain extent. To this end, one purpose of the present invention is to propose a dual temperature sensor control structure for an all-glass liquid heater, which can improve the accuracy of temperature detection and reduce the occurrence of misjudgment.

[0005] The above purpose is achieved through the following technical solutions:

[0006] A dual temperature sensor control structure of an all-glass liquid heater comprises a base assembly and a glass cup body, wherein a control module, a heating module, a first temperature sensor and a second temperature sensor are arranged on the base assembly, the control module is electrically connected to the heating module, the first temperature sensor and the second temperature sensor respectively, the first temperature sensor and the second temperature sensor are arranged at different heights, the glass cup body can be arranged on the base assembly, the first temperature sensor and the second temperature sensor respectively detect the temperature at different heights of the glass cup body, and the control module controls the operation of the heating module according to the detection signals fed back by the first temperature sensor and the second temperature sensor.

[0007] In some embodiments, a depression is disposed on the top of the base assembly, and the first temperature sensor is disposed at a central position of the bottom of the depression.

[0008] In some embodiments, the second temperature sensor is disposed on the top of the base assembly and is located at a vertical position outside the glass body.

[0009] In some embodiments, a mounting seat is vertically disposed on the top of the base assembly, the cross section of the mounting seat is arc-shaped, and the second temperature sensor is disposed on the mounting seat.

[0010] In some embodiments, a mounting hole is opened on the mounting seat, and the second temperature sensor is embedded in the mounting hole and its detection probe protrudes outward from the mounting hole.

[0011] In some embodiments, a step portion is provided at an outer edge of the recess, and the second temperature sensor is provided on the step portion.

[0012] Compared with the prior art, the utility model has at least the following beneficial effects:

[0013] 1. The utility model provides a dual temperature sensor control structure for an all-glass liquid heater, which detects the temperature of the liquid in the glass cup by setting a first temperature sensor and a second temperature sensor at different heights, thereby improving the accuracy of temperature detection and reducing the occurrence of misjudgment.

[0014] 2. The dual temperature sensor control structure of the all-glass liquid heater of the utility model avoids the problem of too long heat dissipation time of the temperature probe when a single thermostat close to the heating source repeatedly and continuously heats. By setting a temperature sensor far away from the heating source to control the low-temperature constant temperature, the current temperature can be accurately and effectively reflected.

[0015] 3. The utility model discloses a dual temperature sensor control structure of an all-glass liquid heater, which detects the temperature of the liquid in the glass cup body by setting the first temperature sensor and the second temperature sensor at different heights. When the water level in the container is lower than the first thermostat, a temperature difference will be formed between the first thermostat and the second thermostat. This principle can effectively prevent dry burning in the presence of water in the container, thereby preventing the cup body from breaking and reducing the occurrence of accidents.

[0016] 4. The utility model provides a dual temperature sensor control structure of an all-glass liquid heater, which detects the temperature of the liquid in the glass cup body by setting the first temperature sensor and the second temperature sensor at different heights. When there is no water in the container and the container is dry-burning, the first thermostat close to the heat source and the second thermostat far away from the heat source have no water as a medium, and a temperature difference will be formed between them and the second thermostat. This principle can effectively prevent the container from being dry-burned without water, which may cause the glass cup body to break, thereby reducing the occurrence of accidents.

[0017] 5. The utility model discloses a dual temperature sensor control structure of a full glass liquid heater, which detects the temperature of the liquid in the glass cup by setting a first temperature sensor and a second temperature sensor at different heights. Especially for induction heating liquid heating appliances, the bottom sensor probe may be affected by electromagnetic interference and environmental interference. As an auxiliary probe for anti-dry burning control, the requirement for its accuracy is greatly reduced. Another probe on the side or other position is responsible for accurately displaying the temperature, which solves the electromagnetic interference and environmental interference problems of different heating elements.

[0021] The following examples illustrate the present invention, but the present invention is not limited by these examples. Modifications to the specific implementation methods of the present invention or equivalent replacement of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed for protection in the present invention.

[0022] Embodiment 1: Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a dual temperature sensor control structure of an all-glass liquid heater, including a base component 1 and a glass cup body 2, wherein a control module, a heating module, a first temperature sensor 3 and a second temperature sensor 4 are arranged on the base component 1, and the control module is electrically connected to the heating module, the first temperature sensor 3 and the second temperature sensor 4 respectively, and the first temperature sensor 3 and the second temperature sensor 4 are arranged at different heights. The glass cup body 2 can be arranged on the base component 1, and the first temperature sensor 3 and the second temperature sensor 4 respectively detect the temperature of the glass cup body 2 at different heights, and the control module controls the operation of the heating module according to the detection signals fed back by the first temperature sensor 3 and the second temperature sensor 4.

[0023] The dual temperature sensor control structure of the all-glass liquid heater provided in this embodiment detects the liquid temperature in the glass cup body 2 by setting the first temperature sensor 3 and the second temperature sensor 4 at different heights, thereby improving the accuracy of temperature detection and reducing the occurrence of misjudgment.

[0024] The advantages of the liquid heater provided in this embodiment include but are not limited to:

[0025] (1) Since the glass cup body 2 is a poor conductor of heat, when the glass container is dry-burned without water, there is a large temperature difference between the position close to the heating surface and the position far from the heating surface because there is no water as a medium to carry heat and transfer temperature. This principle can be used to effectively prevent the glass container from being dry-burned without water. By detecting the temperature of the glass cup body 2 at different heights, the accuracy of temperature detection can be improved.

[0026] (2) When there is water in the glass body 2, when the liquid in the glass body evaporates due to boiling, the sensor at the position without liquid will produce a temperature difference with the sensor at the position with liquid. This principle can be used to prevent dry burning when there is liquid.

[0027] (3) During continuous and repeated heating, a single probe may not dissipate heat in time, resulting in the inability to accurately and timely measure the water temperature in the glass body 2. Therefore, arranging temperature sensors at different positions can effectively solve this problem.

[0028] (4) If it is an induction-heated liquid heating device, the bottom sensor probe may be affected by electromagnetic interference and environmental interference. As an auxiliary probe for anti-dry burning control, the requirements for its accuracy are greatly reduced. Another probe on the side or other position is responsible for accurately displaying the temperature, solving the electromagnetic interference and environmental interference problems of different heating elements.

[0029] In this embodiment, a recess 100 is provided on the top of the base assembly 1, and the first temperature sensor 3 is provided at the center position of the bottom of the recess 100. The recess 100 is provided to facilitate placement and limit the glass cup body 2. The first temperature sensor 3 is provided at the center position of the bottom of the recess 100 so as to detect the temperature at the bottom of the glass cup body 2.

[0030] Preferably, the second temperature sensor 4 is arranged on the top of the base assembly 1 and is located in a vertical position on the outside of the glass cup body 2. It is reasonably designed, so that the position height of the second temperature sensor 4 is higher than the position height of the first temperature sensor 3. The first temperature sensor 3 and the second temperature sensor 4 respectively detect the temperatures at different heights of the glass cup body 2, so as to improve the accuracy of temperature detection and reduce the occurrence of misjudgment.

[0031] More preferably, a mounting seat 11 is vertically arranged on the top of the base assembly 1, and the cross-section of the mounting seat 11 is arc-shaped. The second temperature sensor 4 is arranged on the mounting seat 11. The installation of the second temperature sensor 4 is convenient through the setting of the mounting seat 11, and the arc-shaped design can make the second temperature sensor 4 closer to the glass cup body 2, so as to improve the accuracy of temperature detection.

[0032] In this embodiment, a mounting hole 110 is opened on the mounting seat 11, and the second temperature sensor 4 is embedded in the mounting hole 110 and its detection probe protrudes outward from the mounting hole 110, so as to facilitate the installation and limitation of the second temperature sensor 4.

[0033] Embodiment 2: This embodiment provides a dual temperature sensor control structure of an all-glass liquid heater, which differs from Embodiment 1 in that a step portion is provided at the outer edge of the recess 100, and the second temperature sensor 4 is provided on the step portion, thereby making the position height of the second temperature sensor 4 higher than the position height of the first temperature sensor 3. The first temperature sensor 3 and the second temperature sensor 4 respectively detect the temperatures at different heights of the glass cup body 2, so as to improve the accuracy of temperature detection and reduce the occurrence of misjudgment.

[0034] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
