Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to an anti-dry-burning sensor installation structure and a gas stove. Background Art

[0002] Currently, most household gas cookers use a bracket to secure anti-dry-burn sensors, such as the solution described in patent publication number CN207849444U. This patent employs a fixing structure consisting of a first bracket and a second bracket to clamp the temperature sensor. By adjusting the bracket shape (e.g., L-shaped or V-shaped) and the docking arrangement, the sensor is secured vertically, thereby improving air circulation and gas mixing, thereby enhancing combustion efficiency.

[0003] However, while the aforementioned technology solves the issues of fixing and installing the anti-dry-boil sensor, some shortcomings remain. First, during assembly, the verticality of the sensor is easily affected by the mating surface between the sensor mounting bracket and the burner, resulting in the sensor not being able to fully contact the bottom of the pot, thus affecting the sensor's temperature measurement accuracy. Furthermore, the complex structure of the mounting bracket requires a high level of precision during sensor installation, increasing the difficulty and time required for assembly. Utility Model Content

[0004] Based on the problems in the prior art that the verticality of the anti-dry-burning sensor is easily affected and the installation is complicated, the utility model provides an anti-dry-burning sensor installation structure.

[0010] In some embodiments, the first limiting structure includes a limiting protrusion provided on the outer peripheral side wall of the temperature sensor, and the inner wall of the through hole is correspondingly provided with at least one limiting groove. When the temperature sensor is inserted downward into the through hole, the limiting protrusion cooperates with the limiting groove.

[0011] In some embodiments, the anti-dry-burn sensor assembly further includes a fastener, and the fixing bracket is fastened to the temperature sensor by the fastener being screwed in a radial direction.

[0012] In some embodiments, a side wall of the fixing frame is provided with a mounting slot extending along its axial direction and communicating with the through hole.

[0037] Reference Figures 1-6 , which is an embodiment of the anti-dry burning sensor installation structure of the present utility model.

[0038] The anti-dry-burning sensor installation structure includes a burner head 100 and an anti-dry-burning sensor assembly 200 .

[0039] The burner head 100 has a central channel 110 for guiding gas to the fire cover 3 and fixing a temperature sensor 210 .

[0040] See also Figure 4-Figure 6 The anti-dry-heat sensor assembly 200 includes a fixing bracket 220 and a temperature sensor 210 .

[0041] A through-hole 221 is defined in the center of the mounting bracket 220, extending vertically therethrough. The temperature sensor 210 is coaxially and positionally secured within the through-hole 221, ensuring that the sensor is mounted perpendicular to the central axis of the burner 100. The temperature sensor 210 detects the temperature of the pot bottom and, when the temperature exceeds a predetermined safety threshold, triggers a dry-boil protection measure.

[0042] In addition, the outer peripheral wall of the fixing frame 220 is provided with at least one groove portion 222 extending along its axial direction. After the fixing frame 220 is embedded in the central channel 110 of the burner head 100, the groove portion 222 and the side wall of the central channel 110 together form a gas channel to ensure that the gas can flow smoothly.

[0043] like Figure 3 As shown, the fixing bracket 220 can be coaxially embedded in the central channel 110 and fixed in a limited position, that is, the side wall of the fixing bracket 220 fits tightly with the inner wall of the central channel 110 and is fixed by a limiting structure, thereby ensuring the coaxiality and vertical state between the temperature sensor 210 and the fire cover.

[0044] The above-mentioned anti-dry burning sensor installation structure ensures the coaxiality between the temperature sensor 210 and the fire cover through coaxial embedding, so that the sensor always remains in a vertical state, avoiding temperature measurement errors caused by sensor tilt; at the same time, by providing a groove portion 222 on the outer periphery of the fixing bracket 220, a gas channel is formed together with the side wall of the central channel 110 to ensure the fluidity of the gas, thereby improving combustion efficiency; in addition, the coaxial embedding design of the fixing bracket 220 simplifies the installation process of the sensor, reducing installation time and labor costs.

[0045] In this embodiment, a first limiting structure is provided between the temperature sensor 210 and the fixing bracket 220 for limiting the freedom of movement of the temperature sensor 210 in the axial and radial directions, thereby ensuring the stability of the temperature sensor 210 after installation.

[0046] Specifically, if Figure 5 As shown, the first limiting structure includes an annular limiting protrusion 211 provided on the outer peripheral side wall of the temperature sensor 210, and the inner wall of the through hole 221 is correspondingly provided with an annular limiting groove. When the temperature sensor 210 is installed, the temperature sensor 210 is inserted downward into the through hole 221, and the limiting protrusion 211 is snapped into the limiting groove and tightly fits to achieve limiting, preventing the temperature sensor 210 from moving freely in the axial and radial directions. Through the cooperation between the limiting protrusion 211 and the limiting groove, the temperature sensor 210 can be quickly positioned and installed, and the sensor can also be prevented from being displaced in the axial and radial directions, ensuring the measurement accuracy and reliability of the sensor. One or more limiting grooves can be provided. When multiple vertically arranged limiting grooves are provided, the height of the temperature sensor can be adjusted as needed.

[0047] Furthermore, a fastener (not shown) is added to the anti-dry-burn sensor assembly 200 to fasten the fixing bracket 220 and the temperature sensor 210. Specifically, Figure 4As shown, the sidewall of the fixing bracket 220 is provided with radially extending screw holes 223. Screws or other fasteners are screwed into the screw holes 223 to abut against the sidewalls of the temperature sensor 210, securing the temperature sensor 210. The addition of fasteners further enhances the connection between the temperature sensor 210 and the fixing bracket 220, preventing any axial loosening or displacement of the sensor.

[0048] In this embodiment, if Figure 4 and Figure 6 As shown, the sidewall of the fixing frame 220 is further provided with a mounting slot 224 extending along its axial direction and communicating with the through-hole 221. Since the temperature sensor 210 typically has wires 212 extending from its bottom end, and these wires 212 may be connected to larger components at their ends, the temperature sensor 210 cannot be directly inserted into the fixing frame 220 from top to bottom. Therefore, the mounting slot 224 is specifically provided on the sidewall of the fixing frame 220.

[0049] During installation, wire 212 can be introduced from the outside of mounting bracket 220 through mounting slit 224 into mounting bracket 220, and temperature sensor 210 can then be inserted into through-hole 221. The provision of mounting slit 224 allows wire 212 to smoothly enter mounting bracket 220 while maintaining the installation position of temperature sensor 210. Furthermore, mounting slit 224 acts as a cushion during insertion of temperature sensor 210, reducing insertion resistance through slight deformation, thus helping to ensure smooth and accurate installation of temperature sensor 210.

[0050] The mounting seam 224 is opened along the bottom of the groove portion 222 , that is, opened at the location where the wall thickness of the fixing frame is the smallest, so as to facilitate processing and manufacturing.

[0051] In this embodiment, a second limiting structure is provided between the fixing frame 220 and the central channel 110 , and the second limiting structure is used to limit the downward movement freedom of the fixing frame 220 .

[0052] Specifically, if Figure 6 , the top of the fixing frame 220 is provided with a limiting flange 225; Figure 3 A stop step 111 is provided within the central channel 110 of the burner head 100. A stop flange 225 and the stop step 111 form the second stop structure. When the fixing bracket 220 is inserted into the central channel 110, the stop flange 225 and the stop step 111 cooperate to hold the fixing bracket 220 in place, ensuring that the fixing bracket 220 maintains its precise position after installation and is not subject to downward movement due to external forces.

[0053] In this embodiment, the fixing frame 220 is an integrally formed structure. This integrally formed structure provides high strength and rigidity, is less susceptible to deformation, and can better ensure the coaxiality of the temperature sensor 210. Furthermore, the integrally formed structure simplifies the manufacturing process, reduces production costs, and improves production efficiency.

[0054] The utility model also includes a gas stove, which includes the above-mentioned anti-dry burning sensor installation structure.

[0055] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the above embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the above embodiments, or to replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present invention.
