Description

Technical Field

[0001] The utility model relates to the technical field of temperature detection, in particular to a temperature control probe and a gas cooker comprising the same. Background Art

[0002] When a gas stove is heating a pot, in order to prevent the pot from being too hot due to dry burning in the pot, the temperature of the pot needs to be measured. When the pot is detected to be in a dry burning state, the gas stove can be extinguished in time. Since the gas stove will generate a large amount of high-temperature flue gas at the position where the temperature control probe is set during the heating process, the heat generated by the high-temperature flue gas will be transferred to the outer shell of the temperature control probe, and then the heat will be transferred to the heat collecting plate on the top of the temperature control probe through the outer shell, which will cause the temperature difference between the bottom of the pot measured by the temperature control probe and the actual bottom of the pot to be too large, resulting in the flame of the stove being extinguished by mistake. In order to avoid this situation, the outer shell corresponding to the existing temperature control probe is generally made of ceramic material to avoid temperature conduction, but since the temperature control probe is generally in contact with the bottom of the pot during use, the position of the temperature control probe is relatively high, and when the user places the pot, it is easy to collide with the side wall of the temperature control probe, thereby causing the outer shell of the temperature control probe to be broken, reducing the reliability of the use of the temperature control probe. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the defect in the prior art that the shell of the temperature control probe made of ceramic material is easily colliding with the cooker and being broken, and to provide a temperature control probe and a gas cooker including the same.

[0004] The utility model solves the above technical problems through the following technical solutions:

[0005] A temperature control probe, characterized in that the temperature control probe comprises:

[0006] A probe body and a shell, wherein in the axial direction of the probe body, the shell at least surrounds the periphery of the upper portion of the probe body;

[0007] The shell includes a ceramic segment and a metal segment connected to each other along its axial direction. The ceramic segment is arranged between the metal segment and the heat collecting plate of the probe body, and in the axial direction of the probe body, the projection of the ceramic segment is located within the projection range of the metal segment.

[0008] In the present solution, a shell is provided around at least the outer periphery of the upper part of the probe body. On the one hand, the probe body is separated from the external high-temperature flue gas by the shell to avoid direct contact between the high-temperature flue gas and the probe body, thereby transferring heat to the probe body. On the other hand, the metal segment is separated from the heat collecting plate of the probe body by the ceramic segment in the shell. The poor thermal conductivity of the ceramic segment is utilized to avoid direct transfer of heat on the metal segment to the heat collecting plate of the probe body, thereby avoiding to a large extent the large difference between the pot bottom temperature measured by the temperature control probe and the actual pot bottom temperature. At the same time, in the axial direction of the probe body, the projection of the ceramic segment is located within the projection range of the metal segment. When the user places the pot by moving the pot horizontally, even if the pot collides with the temperature control probe, it will first collide with the metal segment, thereby avoiding the ceramic segment from being smashed by the collision, further improving the reliability of the temperature control probe.

[0009] Furthermore, the central axes of the ceramic segment and the metal segment coincide with each other, and the maximum distance between the peripheral wall of the ceramic segment and its central axis is smaller than the minimum distance between the peripheral wall of the metal segment and its central axis.

[0010] In the present solution, a preferred shell setting method is provided, that is, the central axes of the ceramic segment and the metal segment are arranged to overlap, and the distance dimensions from the outer walls of the ceramic segment and the metal segment to their respective central axes are arranged so that in the axial direction of the probe body, the projection of the ceramic segment can be located within the projection range of the metal segment, so that when the user moves the pot horizontally and collides with the temperature control probe, the metal segment can be used to protect the ceramic segment.

[0011] Furthermore, the ceramic segment and the metal segment are both cylindrical structures, the central axes of the ceramic segment and the metal segment coincide with each other, and the radial dimension of the ceramic segment is smaller than the radial dimension of the metal segment.

[0012] In this scheme, a better shell setting method is provided, that is, the ceramic segment and the metal segment are set as cylindrical structures whose central axes overlap with each other, and the radial dimensions of the ceramic segment and the metal segment are relatively adjusted, so that in the axial direction of the probe body, the projection of the ceramic segment can be located within the projection range of the metal segment, and the metal segment can also be used to provide corresponding protection for the ceramic segment.

[0013] Furthermore, the radial dimension of the ceramic segment is A, and the radial dimension of the metal segment is B; wherein BA≥0.5 mm.

[0014] In this solution, a better dimension setting method is provided so that the projection of the ceramic segment can be located within the projection range of the metal segment, thereby realizing corresponding protection of the ceramic segment by the metal segment.

[0015] Furthermore, in the axial direction of the probe body, one end of the ceramic segment abuts against the heat collecting plate of the probe body, and the other end of the ceramic segment extends inward along the radial direction of the probe body to form a protrusion, and the ceramic segment is interference fit with the probe body through the protrusion.

[0016] In the present scheme, through this arrangement, one end of the ceramic segment is used to abut against the heat collecting plate of the probe body to avoid a gap between the ceramic segment and the heat collecting plate, thereby preventing the high-temperature flue gas outside the temperature control probe from contacting the probe body through the end of the ceramic segment; at the same time, the raised portion on the ceramic segment is used to perform an interference fit with the probe body. Since the thermal conductivity of the ceramic segment is poor, while the ceramic segment is fixed relative to the probe body, heat will not be directly transferred to the probe body, thereby ensuring that the temperature measured by the temperature control probe is close to the temperature of the bottom of the pot.

[0017] Furthermore, the end of the metal segment close to the ceramic segment is bent inward to form a first bending surface and a second bending surface in sequence, the first bending surface is horizontally arranged between the outer wall of the ceramic segment and the second bending surface, the metal segment is abutted against the ceramic segment through the first bending surface, and the metal segment is interference fit with the probe body through the second bending surface.

[0018] In the present solution, through this arrangement, the first bending surface of the metal segment that is horizontally bent inward is used to abut against the ceramic segment, which can also avoid the generation of a gap between the ceramic segment and the metal segment, thereby preventing the high-temperature flue gas outside the temperature control probe from directly contacting the probe body; at the same time, the metal segment is interference fit with the probe body through the second bending surface, so that the metal segment is fixed relative to the probe body, and because the position of the metal segment corresponding to the probe body is not the temperature sensing component in the probe body, the heat on the metal segment is transferred to the probe body, and it will not cause too much impact on the temperature sensing component, thereby ensuring that the temperature measured by the temperature control probe can still be close to the temperature of the bottom of the pot.

[0019] Furthermore, a heat-insulating space is formed between the outer side wall of the metal segment and the probe body, and one end of the metal segment away from the ceramic segment is an opening structure, and the heat-insulating space is connected with the external space through the opening structure.

[0020] In the present solution, through this arrangement, the metal segment and the probe body are not completely fitted together, but cooperate with each other to form an insulating space. On the one hand, the smoke heat outside the probe body can be isolated on the outside of the metal segment, and on the other hand, the opening structure of the metal segment can be used to dissipate the heat in the insulating space, thereby avoiding the smoke heat outside the temperature control probe from being transferred to the probe body, thereby ensuring that the temperature measured by the temperature control probe can be close to the temperature of the bottom of the pot.

[0021] Furthermore, in the axial direction of the probe body, the extension dimension of the ceramic segment is A, and the value range of A is between 1 mm and 5 mm;

[0022] And / or, in the axial direction of the probe body, the extension dimension of the metal segment is B, and the value range of B is between 30 mm and 40 mm.

[0023] In the present solution, the extension dimension of the ceramic segment along the axial direction of the probe body is set within a certain range, so as to avoid the ceramic segment extending too short and failing to reduce the temperature transfer, and also avoid the ceramic segment extending too long and causing increased costs and damage. At the same time, the extension dimension of the metal segment along the axial direction of the probe body is set within a certain range, so as to avoid the metal segment extending too short and failing to isolate the external high-temperature flue gas, and also avoid the metal segment extending too long and causing increased costs and other problems.

[0024] Furthermore, the probe body includes a heat collecting sheet, a protective cover and a thermistor component. The heat collecting sheet is arranged at the end of the protective cover. One end of the thermistor component abuts against the heat collecting sheet inside the protective cover, and the other end is led out from the inside of the protective cover. The ceramic segment is arranged around the periphery of the protective cover and abuts against the heat collecting sheet.

[0025] In the present solution, the probe body specifically includes a heat collecting sheet, a protective cover and a thermistor component. The heat collecting sheet is used to contact the bottom of the cookware so as to increase the contact area with the bottom of the cookware, and then the heat collecting sheet is used to transfer heat to the thermistor component to better sense the temperature of the bottom of the cookware. At the same time, the ceramic segment is specifically arranged around the periphery of the protective cover and abuts against the heat collecting sheet, so that the position of the ceramic segment corresponds to the end position of the thermistor component in contact with the heat collecting sheet, thereby effectively preventing the smoke heat outside the probe body from being directly transferred to the end of the thermistor component in contact with the heat collecting sheet.

[0026] A gas cooker is characterized in that it comprises the temperature control probe as described above.

[0027] In this solution, the gas cooker includes the temperature control probe as described above, so as to realize the temperature reduction transfer of the ceramic segment while preventing it from colliding and being broken.

[0028] The positive and progressive effects of the utility model are:

[0029] By providing a shell around at least the outer periphery of the upper part of the probe body, on the one hand, the probe body is separated from the external high-temperature flue gas by the shell to avoid direct contact between the high-temperature flue gas and the probe body, thereby transferring heat to the high-temperature flue gas; on the other hand, the metal segment is separated from the heat collecting plate of the probe body by the ceramic segment in the shell, and the poor thermal conductivity of the ceramic segment is utilized to avoid direct transfer of heat on the metal segment to the heat collecting plate of the probe body, thereby avoiding to a large extent the large difference between the pot bottom temperature measured by the temperature control probe and the actual pot bottom temperature; at the same time, in the axial direction of the probe body, the projection of the ceramic segment is located within the projection range of the metal segment. When the user places the pot by moving the pot horizontally, even if the pot collides with the temperature control probe, it will first collide with the metal segment, thereby avoiding the ceramic segment from being smashed by the collision, further improving the reliability of the temperature control probe.

In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0053] This embodiment provides a temperature control probe 1, such as Figure 1 , Figure 2 and Figure 3 As shown, the temperature control probe 1 includes a probe body, and the probe body includes a heat collecting sheet 11, a protective cover 12 and a thermal sensitive component 13. Figure 6As shown, the overall structure of the protective cover 12 is a cylindrical structure with a through-hole inside. One end of the protective cover 12 extends outward in the radial direction, and a heat collecting sheet 11 is arranged at the one end. A thermosensitive component 13 is arranged inside the protective cover 12. One end of the thermosensitive component 13 abuts against the heat collecting sheet 11 inside the protective cover 12, and the other end is led out from the inside of the protective cover 12. When the user is cooking, the bottom of the pot can be placed on the temperature control probe 1, and the heat collecting sheet 11 of the probe body can be used to contact the bottom of the pot to transfer the bottom temperature of the pot to the heat collecting sheet 11, and then further to the thermosensitive component 13, and the thermosensitive component 13 can be used to output the acquired temperature. Regarding the specific material and structure of the thermosensitive component 13, the solutions existing in the prior art can be adopted, and no further description is given.

[0054] like Figure 1 , Figure 2 and Figure 3 As shown, the temperature control probe 1 further includes a housing 20, which is arranged around the periphery of the upper part of the probe body in the axial direction H of the probe body. The housing 20 includes a ceramic segment 21 and a metal segment 22 connected to each other along its axial direction, the ceramic segment 21 is arranged between the metal segment 22 and the heat collecting sheet 11 of the probe body, and in the axial direction H of the probe body, the projection of the ceramic segment 21 is located within the projection range of the metal segment 22.

[0055] Through this arrangement, on the one hand, the probe body is separated from the external high-temperature flue gas by the shell 20 to avoid direct contact between the high-temperature flue gas and the probe body, thereby transferring heat to the probe body; on the other hand, the metal segment 22 is separated from the heat collecting plate 11 of the probe body by the ceramic segment 21 in the shell 20, and the poor thermal conductivity of the ceramic segment 21 is utilized to avoid the heat on the metal segment 22 being directly transferred to the heat collecting plate 11 of the probe body, thereby largely avoiding the large difference between the pot bottom temperature measured by the temperature control probe 1 and the actual pot bottom temperature; at the same time, in the axial direction H of the probe body, the projection of the ceramic segment 21 is located within the projection range of the metal segment 22. When the user places the pot by moving the pot horizontally, even if the pot collides with the temperature control probe 1, it will first collide with the metal segment 22, thereby avoiding the ceramic segment 21 from being collided and broken, further improving the reliability of the temperature control probe 1.

[0056] Combination Figure 4 and Figure 5As shown, the main structures of the ceramic segment 21 and the metal segment 22 of the housing 20 are both cylindrical structures, the central axes of the ceramic segment 21 and the metal segment 22 coincide with each other, and the radial dimension of the ceramic segment 21 is smaller than the radial dimension of the metal segment 22. By setting the ceramic segment 21 and the metal segment 22 as cylindrical structures whose central axes coincide with each other, and adjusting the radial dimensions of the ceramic segment 21 and the metal segment 22 relatively, the projection of the ceramic segment 21 can be located within the projection range of the metal segment 22 in the axial direction H of the probe body, so that when the user moves the pot horizontally and collides with the temperature control probe 1, the metal segment 22 can be used to protect the ceramic segment 21.

[0057] Furthermore, the radial dimension of the ceramic segment 21 is A, and the radial dimension of the metal segment 22 is B; wherein BA≥0.5 mm. This preferred dimension setting method can make the projection of the ceramic segment 21 completely within the projection range of the metal segment 22, so that the metal segment 22 can be used to protect the ceramic segment 21 accordingly.

[0058] In this embodiment, since the main structure of the ceramic segment 21 and the metal segment 22 is a cylindrical structure, the radial dimensions of the ceramic segment 21 and the metal segment 22 are the radius dimensions of the ceramic segment 21 and the metal segment 22. Due to the corresponding preferred size setting, the diameter dimension of the metal segment 22 is at least 1 mm larger than the diameter dimension of the ceramic segment 21.

[0059] However, in other alternative embodiments, the ceramic segment 21 and the metal segment 22 may not be configured as a cylindrical structure, for example, they may be configured as a column structure with a quadrilateral or polygonal cross section, in which case the central axes of the ceramic segment 21 and the metal segment 22 may also coincide with each other, and the maximum distance dimension between the peripheral wall of the ceramic segment 21 and its central axis is smaller than the minimum distance dimension between the peripheral wall of the metal segment 22 and its central axis. Through this configuration, in the axial direction H of the probe body, the projection of the ceramic segment 21 may be located within the projection range of the metal segment 22, and the metal segment 22 may also be used to provide corresponding protection to the ceramic segment 21.

[0060] like Figure 3 and Figure 4As shown, in the axial direction H of the probe body, one end of the ceramic segment 21 abuts against the heat collecting sheet 11 of the probe body, and the other end of the ceramic segment 21 extends inward along the radial direction of the probe body to form a protrusion 211, and the ceramic segment 21 is interference-fitted with the probe body through the protrusion 211. Through this arrangement, one end of the ceramic segment 21 abuts against the heat collecting sheet 11 of the probe body to avoid a gap between the ceramic segment 21 and the heat collecting sheet 11, thereby preventing the high-temperature flue gas outside the temperature control probe 1 from contacting the probe body through the end of the ceramic segment 21; at the same time, the protrusion 211 on the ceramic segment 21 is interference-fitted with the probe body. Due to the poor thermal conductivity of the ceramic segment 21, while ensuring that the ceramic segment 21 is fixed relative to the probe body, heat will not be directly transferred to the probe body, thereby ensuring that the temperature measured by the temperature control probe 1 is close to the temperature of the bottom of the pot. However, in other alternative embodiments, the ceramic segment 21 may not be provided with the protrusion 211, but may be fixed relative to the heat collecting plate 11 of the probe body by gluing or the like, or may be fixed by other methods existing in the prior art.

[0061] like Figure 3 and Figure 5 As shown, one end of the metal segment 22 of the shell 20 is bent inward to form a first bending surface 222 and a second bending surface 223 in sequence, the first bending surface 222 is horizontally arranged between the outer wall 221 of the ceramic segment 21 and the second bending surface 223, the metal segment 22 is abutted against the ceramic segment 21 through the first bending surface 222, and the metal segment 22 is interference fit with the probe body through the second bending surface 223. With this arrangement, the first bending surface 222 of the metal segment 22 that is horizontally bent inward is in contact with the ceramic segment 21, which can also avoid a gap between the ceramic segment 21 and the metal segment 22, thereby preventing the high-temperature flue gas outside the temperature control probe 1 from directly contacting the probe body; at the same time, the metal segment 22 is interference-fitted with the probe body through the second bending surface 223, so that the metal segment 22 is fixed relative to the probe body. Since the position of the metal segment 22 corresponding to the probe body is not the temperature sensing component in the probe body, the heat on the metal segment 22 is transferred to the probe body without causing too much impact on the temperature sensing component, thereby ensuring that the temperature measured by the temperature control probe 1 can still be close to the temperature of the bottom of the pot.

[0062] Similarly, in other alternative embodiments, the metal segment 22 may not be provided with the first bending surface 222 and the second bending surface 223, but may be fixed relative to the ceramic segment 21 by gluing or the like, or may be fixed by other methods existing in the prior art.

[0063] In this embodiment, one end of the metal segment 22 is bent inward to form a first bending surface 222 and a second bending surface 223 in sequence, and the second bending surface 223 is interference-fitted with the probe body. Figure 2 As shown, a heat-insulating space 30 can be formed between the outer wall 221 of the metal segment 22 and the probe body, and the end of the metal segment 22 away from the ceramic segment 21 is an open structure, and the heat-insulating space 30 is connected to the outside space through the opening structure. Through this arrangement, the metal segment 22 and the probe body are not completely fitted, but cooperate with each other to form a heat-insulating space 30. On the one hand, the heat of the flue gas outside the probe body can be isolated on the outside of the metal segment 22, and on the other hand, the heat in the heat-insulating space 30 can be dissipated by using the opening structure of the metal segment 22, thereby preventing the heat of the flue gas outside the temperature control probe 1 from being transferred to the probe body, thereby ensuring that the temperature measured by the temperature control probe 1 can be close to the temperature of the bottom of the pot.

[0064] In addition, in the axial direction H of the probe body, the extension dimension of the ceramic segment 21 is A, and the value range of A is between 1mm and 5mm. By setting the extension dimension of the ceramic segment 21 along the axial direction H of the probe body within a certain range, the extension dimension of the ceramic segment 21 is prevented from being too short and failing to reduce the temperature transfer, and the extension dimension of the ceramic segment 21 is prevented from being too long, causing increased costs and damage. In the axial direction H of the probe body, the extension dimension of the metal segment 22 is B, and the value range of B is between 30mm and 40mm. By setting the extension dimension of the metal segment 22 along the axial direction H of the probe body within a certain range, the extension dimension of the metal segment 22 is prevented from being too short and failing to isolate the external high-temperature flue gas, and the extension dimension of the metal segment 22 is prevented from being too long, causing increased costs and other problems.

[0065] It should be noted that the range of the above dimensions is specifically determined according to the size of the burner and the height of the pot rack, that is, the specific size can be selected as needed to meet the matching of different pots and the temperature control probe 1, thereby meeting the use of different pots.

[0066] In addition, this embodiment also discloses a gas cooker, which includes the temperature control probe 1 as described above, so as to prevent the ceramic segment 21 from being shattered by collision while realizing temperature reduction transmission of the ceramic segment 21 .

[0067] Although the specific implementations of the utility model are described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the attached claims. Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
