Description

Technical Field

[0001] The invention relates to the technical field of kitchen appliances, and in particular to an anti-dry burning component and a gas stove. Background Art

[0002] With the rapid economic development, people's living standards are gradually improving, and users have higher requirements on the functions that household gas stoves should include. Therefore, gas stoves with anti-dry burning function are becoming more and more popular among consumers.

[0003] The gas stoves with anti-dry burning function on the market usually add a temperature sensor to the burner to detect the temperature of the bottom of the pot. When the temperature of the bottom of the pot is higher than the preset value, the stove will stop working. Using an anti-dry burning gas stove can not only prevent the cooking utensils from being burned dry, but also prevent the oil temperature in the pot from being too high, causing excessive harmful substances in the cooked food.

[0004] However, when the temperature sensor detects the temperature of the pot body, the temperature probe in the temperature sensor needs to abut against the bottom of the pot to ensure the accuracy of the detected temperature. Summary of the invention

[0011] Optionally, an opening is provided on a peripheral wall of the first mounting hole in the axial direction, a circuit is provided in the thermal insulation sleeve, and a portion of the circuit is suitable for passing through the opening and entering the first mounting hole.

[0012] Optionally, the mounting structure includes a second mounting hole, and the mounting bracket is clamped on the second mounting hole, wherein a clamping structure suitable for being clamped in the second mounting hole is formed on the mounting bracket.

[0013] Optionally, the clamping structure is a plurality of limiting ribs formed on the outer peripheral wall of the first mounting hole, and the top end surfaces of the limiting ribs abut against the inner peripheral surface of the first mounting hole.

[0014] Optionally, the central axis of the second mounting hole is suitable for being arranged colinearly with the central axis of the ignition divider.

[0015] Optionally, a mounting plate is protruding from the lower end of the peripheral wall of the first mounting hole, and the mounting plate abuts against the lower end of the second mounting hole.

[0016] Optionally, a positioning structure is provided at the mating mounting position between the mounting plate and the second mounting hole, and the positioning structure includes a positioning groove and a positioning protrusion that cooperate with each other, one of which is provided on the mounting plate, and the other of which is provided at the second mounting hole.

[0017] The present invention also provides a gas stove including any one of the above-mentioned anti-dry burning components.

[0018] The technical solution of the present invention has the following advantages:

[0019] 1. The anti-dry burning assembly in the present invention includes a temperature sensing element, which includes a temperature sensing probe and a heat-insulating sleeve connected to the lower end of the temperature sensing probe, and also includes: a mounting structure, which is arranged on the burner; a mounting bracket, which is arranged on the mounting structure, and the heat-insulating sleeve is arranged on the mounting bracket, and after the mounting bracket is installed in place, the temperature sensing probe is suitable for abutting against the bottom of the cookware.

[0020] In the present invention, a mounting bracket is provided on the burner head, and a temperature sensing element is mounted on the mounting bracket, thereby realizing fixed installation of the temperature sensing element on the gas stove. After being fixed in place, a temperature sensing probe in the temperature sensing element abuts against the bottom of the pot, thereby realizing real-time detection of the pot temperature and preventing the occurrence of dry burning problems.

[0021] 2. In the anti-dry burning assembly of the present invention, a first mounting hole is provided on the mounting bracket, and the thermal insulation sleeve is inserted into the first mounting hole. An interference fit installation method can be adopted between the outer tube wall of the thermal insulation sleeve and the first mounting hole to ensure that the thermal insulation sleeve can be inserted and fixed in the first mounting hole, and the installation is simple and convenient.

[0022] 3. The anti-dry burning assembly of the present invention also includes a pressing piece. At least one pressing hole is provided on the peripheral wall of the first mounting hole. The pressing piece is provided on the pressing hole and passes through the pressing hole to abut against the peripheral wall of the thermal insulation sleeve. The pressing piece abuts against the peripheral wall of the thermal insulation sleeve, which can further strengthen the fixation of the thermal insulation sleeve and prevent the thermal insulation sleeve from moving up and down.

[0023] 4. In the anti-dry burning assembly of the present invention, a reinforcing rib is protruded on the peripheral wall of the first mounting hole, and the top pressure hole is arranged on the reinforcing rib. The top pressure hole is generally a threaded hole. By arranging the top pressure hole at the position of the reinforcing rib, the strength of the hole wall of the first mounting hole at the position of the top pressure hole can be effectively strengthened to prevent it from deformation.

[0024] 5. At least one limiting rib is arranged on the inner peripheral wall of the first mounting hole in the anti-dry-burning assembly of the present invention, and a limiting protrusion cooperating with the limiting rib is arranged on the peripheral wall of the heat-insulating sleeve. The setting of the limiting protrusion can prevent the temperature sensing element from being further pressed down under the pressure of the external cookware, resulting in the temperature sensing probe being unable to abut against the cookware when the cookware comes over next time, causing problems with the anti-dry-burning function.

[0025] 6. In the anti-dry burning assembly of the present invention, an opening is provided on the peripheral wall of the first mounting hole, and a circuit is provided in the heat-insulating sleeve, and part of the circuit is suitable for passing through the opening to enter the first mounting hole. In some temperature sensing elements, the volume of the wiring terminal is large and cannot pass through the first mounting hole. In order to simplify the installation, an opening is provided on the peripheral wall of the first mounting hole to facilitate the installation of the circuit in the temperature sensing element.

[0026] 7. The clamping structure in the anti-dry-burning assembly of the present invention is a plurality of limiting ribs formed on the outer peripheral wall of the first mounting hole, and the top surface of the limiting ribs abuts against the inner peripheral surface of the first mounting hole. Since the temperature sensing probe abuts against the bottom of the cookware, when the cookware moves, it is easy to cause the temperature sensing probe to shake. Over time, it is easy to cause the temperature sensing probe to shift, resulting in its inability to abut against the bottom of the cookware. The setting of the limiting ribs can effectively prevent the shaking of the temperature sensing probe and prevent the problem of displacement of the temperature sensing probe.

[0027] 8. The central axis of the second mounting hole in the anti-dry-burning assembly of the present invention is suitable for being arranged colinearly with the central axis of the ignition divider, which can ensure that the temperature sensing probe abuts at the center of the bottom of the cookware. When the cookware is a round-bottomed pot, it can prevent the temperature sensing probe from abutting against the cookware and causing abutment deviation. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0044] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0046] Example 1

[0047] like Figures 1 to 5 As shown, an anti-dry burning component provided in this embodiment includes a temperature sensing element 1, the temperature sensing element 1 includes a temperature sensing probe 11 and a heat insulating sleeve 12 connected to the lower end of the temperature sensing probe 11, and also includes: a mounting structure 31, which is arranged on the burner head 3; a mounting bracket 2, which is arranged on the mounting structure 31, and the heat insulating sleeve 12 is arranged on the mounting bracket 2, and after the mounting bracket 2 is installed in place, the temperature sensing probe 11 is suitable for abutting against the bottom of the cookware.

[0048] The temperature sensing element 1 in this embodiment is a temperature sensor used on a gas stove, which includes a temperature sensing probe 11. The temperature sensing probe 11 abuts against the cookware when in use to detect the temperature of the cookware in real time. The outer side of the temperature sensing probe is a protective shell, and the inner side has a spring and an abutting portion abutting against the cookware. When the cookware is placed on the stove, the bottom of the cookware presses down the abutting portion, the spring is compressed, and the reverse force of the spring makes the abutting portion always abut against the bottom of the cookware.

[0049] In order to realize the installation of the above-mentioned temperature sensor, a mounting structure is designed on the burner head 3 in this embodiment, and a mounting bracket 2 for mounting the temperature sensor is designed in addition. The temperature sensing element 1 is mounted on the mounting bracket 2, and the mounting bracket 2 is mounted on the mounting structure 31 of the burner head 3, so that the temperature sensor is fixed on the gas stove. In order to realize the accurate measurement of the temperature of the bottom of the pot, the installation position of the temperature sensor should ensure that the temperature sensing probe 11 can abut against the bottom of the pot after the installation is completed.

[0050] In order to simplify the installation of the temperature sensor for the user, the following structure is designed in this embodiment:

[0051] The main body of the mounting bracket 2 in this embodiment is a columnar structure, and a first mounting hole 21 is processed on the main structure. The thermal insulation sleeve 12 is inserted into the first mounting hole 21. The aperture of the first mounting hole 21 in this embodiment is larger than the outer diameter of the thermal insulation sleeve 12. In order to prevent the thermal insulation sleeve 12 from axially moving in the first mounting hole, a top pressure hole 22 is provided on the peripheral wall of the first mounting hole in this embodiment. The top pressure member 4 is provided on the top pressure hole 22, and passes through the top pressure hole 22 to abut against the peripheral wall of the thermal insulation sleeve 12. The top pressure member 4 in this embodiment is a common screw, and the top pressure hole 22 is a common screw hole. The screw is screwed on the screw hole, and the tail end of the screw is constantly pressed against the outer peripheral wall of the thermal insulation sleeve 12, thereby fixing the thermal insulation sleeve. The thermal insulation sleeve in this embodiment is internally a circuit for realizing communication and power supply of the temperature sensor, and externally an insulating protective shell. The insulating protective shell has a certain hardness and can withstand a certain extrusion force.

[0052] As a modified implementation, the temperature sensor can be fixed by using a side interference fit between the heat insulating sleeve 12 and the first mounting hole 21. This operation method is simple and convenient, and has high assembly efficiency.

[0053] Because the area near the top pressure hole needs to withstand a certain pressure, and the hole wall of the first mounting hole is generally thin, in order to ensure the structural strength of the top pressure hole, in this embodiment, a reinforcing rib 25 is protruded on the peripheral wall of the first mounting hole 21, and the top pressure hole 22 is arranged on the reinforcing rib 25.

[0054] In order to accurately locate the installation depth of the thermal insulation sleeve in the first mounting hole 21, in this embodiment, a limit retaining rib 23 is provided on the inner peripheral wall of the first mounting hole 21. The limit retaining rib 23 is an annular retaining rib. As a deformation, it can also be a structure such as a plurality of convex points. A limit protrusion 121 cooperating with the limit retaining rib 23 is provided on the peripheral wall of the thermal insulation sleeve 12. When the thermal insulation sleeve 12 is installed, it is blocked by the limit retaining rib 23 when it is inserted into the first mounting hole. At this time, the top pressure piece can be used to fix it. This design can ensure the distance from the temperature sensing probe to the bottom of the pot, and ensure that the temperature sensing probe can effectively abut against the bottom of the pot when the pot is installed.

[0055] In some temperature sensing elements, the volume of the wiring terminal is large and cannot pass through the first mounting hole. In order to simplify the installation, an opening is provided on the peripheral wall of the first mounting hole to facilitate the installation of the circuit in the temperature sensing element. Specifically, in this embodiment, along the axial direction, an opening 24 is provided on the peripheral wall of the first mounting hole 21, and a circuit is provided in the thermal insulation sleeve 12, and part of the circuit is suitable for passing through the opening 24 and entering the first mounting hole 21.

[0056] The following explains how the mounting bracket is installed on the burner:

[0057] In this embodiment, the mounting structure 31 on the burner head includes a second mounting hole 311, and the mounting bracket 2 is clamped on the second mounting hole 311, wherein the mounting bracket 2 is formed with a clamping structure 26 suitable for clamping in the second mounting hole 311. The clamping structure 26 is a plurality of limiting ribs formed on the outer peripheral wall of the first mounting hole 21, and the top surface of the limiting ribs abuts against the inner peripheral surface of the first mounting hole 21. Because the temperature sensing probe abuts against the bottom of the pot, when the pot moves, it is easy to drive the temperature sensing probe to shake, and over time, it is easy to cause the temperature sensing probe to shift, resulting in it being unable to abut against the bottom of the pot. The setting of the limiting ribs can effectively prevent the shaking of the temperature sensing probe and prevent the problem of displacement of the temperature sensing probe.

[0058] Furthermore, the central axis of the second mounting hole 311 in this embodiment is suitable for being arranged in line with the central axis of the fire distributor 5. This ensures that the temperature sensing probe abuts at the center of the bottom of the pot, and when the pot is a round bottom pot, it can prevent the temperature sensing probe from abutting against the pot and causing abutment deviation.

[0059] In order to fix the mounting bracket on the mounting structure, a mounting plate 27 is protruded from the lower end of the peripheral wall of the first mounting hole 21 on the mounting bracket in this embodiment, and the mounting plate 27 abuts against the lower end of the second mounting hole 311, and the two are locked together by screws.

[0060] Further, in order to achieve rapid positioning and installation, a positioning structure is provided at the matching installation position of the mounting plate 27 and the second mounting hole 311 in this embodiment, and the positioning structure includes a positioning groove 6 and a positioning protrusion 7 that cooperate with each other, one of which is provided on the mounting plate 27, and the other of which is provided at the second mounting hole 311. In this embodiment, a positioning groove 6 is formed on the mounting plate 27, and a positioning protrusion 7 is formed on the burner head. As a variation, the positioning protrusion 7 is also formed on the mounting plate 27, and the positioning groove 6 is formed on the burner head.

[0063] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
