Description

Technical Field

[0001] The utility model relates to the field of burners, in particular to a pot support and a burner comprising the same. Background Art

[0002] In order to prevent the pot placed on the burner from burning dry, which may damage the pot or cause a fire accident, in the prior art, the burner often includes a probe. The principle of the probe for preventing dry burning is as follows: when the pot is placed on the burner, the probe abuts against the bottom of the pot to detect the temperature of the bottom of the pot in real time; when the liquid in the pot is burned dry, the temperature of the bottom of the pot will rise abnormally and reach the flameout threshold; at this time, the controller receives data from the probe, which controls the combustion part of the burner to extinguish. Usually, the structure of the burner is set as follows: the probe is located at the top of the combustion part and is surrounded by the pot frame. The probe can rebound to the initial position after being compressed, so that the probe can adapt to different center positions of the bottom of the pot.

[0003] However, in actual use, the following problems arise: the high-temperature flue gas generated by the combustion part is distributed around the burner, and the temperature of the high-temperature flue gas is transmitted to the probe, which can easily cause misjudgment; that is, even if the pot is not dry-burned, the probe will also sense the temperature reaching the flameout threshold due to the influence of the high-temperature flue gas, thereby causing unnecessary flameout and affecting the user experience. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the defect of the prior art that high-temperature flue gas affects the sensing temperature of the anti-dry burning probe, and to provide a pot bracket and a burner comprising the same.

[0005] The utility model solves the above technical problems through the following technical solutions:

[0006] A pot support, comprising a plurality of legs, the pot support further comprising a heat insulating member, the heat insulating member being able to be enclosed around a burner anti-dry burning probe;

[0007] The heat insulating member is located between the plurality of legs, and the plurality of legs extend toward the heat insulating member and are respectively connected to the heat insulating member;

[0008] The axes of the upper surfaces of the inclined portions of the plurality of support legs intersect at the same intersection point, and the upper end of the thermal insulation member is located at or below the horizontal plane where the intersection point is located.

[0009] In the technical solution, when a pot support is installed on a burner, the heat insulation provided in the pot support can enclose the heat insulation on the side of the anti-dry-burning probe of the burner, which can block the high-temperature flue gas and prevent the heat of the high-temperature flue gas from affecting the sensing temperature of the anti-dry-burning probe and causing the problem of false alarm. Furthermore, by connecting the heat insulation to the support foot, the temperature of the heat insulation can be transferred to the support foot with a lower temperature in time. Compared with the setting of connecting the heat insulation to other relatively high-temperature structures in the burner, the technical solution can better cool the heat insulation, further avoiding the situation where the heat insulation is heated by the high-temperature flue gas and the heat is released around the anti-dry-burning probe, affecting the sensing temperature of the anti-dry-burning probe. In addition, by setting the upper end of the heat insulation to be located at or below the horizontal plane where the intersection is located, it can reduce the situation where the heat insulation is hit by the bottom of the pot when the bottom of the pot is placed on the pot support and is broken.

[0010] Preferably, the support leg and the thermal insulation member are integrally formed; and / or,

[0011] The support legs and the thermal insulation member are made of the same material.

[0012] In the technical solution, by setting the support leg and the heat insulating member to be integrally formed, it is possible to avoid the problem that after the support leg and the heat insulating member are separately formed, due to being in a high temperature environment during use, the two will expand and contract separately, causing the connection to fall off or be excessively squeezed against each other. By setting the support leg and the heat insulating member to be made of the same material, it is possible to avoid the problem that the thermal expansion coefficients of the materials of the support leg and the heat insulating member are too different, and due to being in a high temperature environment during use, the two will expand and contract separately, causing the connection to fall off or be excessively squeezed against each other.

[0013] Preferably, the angle between the upper surface of the inclined portion and the horizontal plane is in the range of 10°-20°.

[0014] In the present technical solution, by setting the angle between the upper surface of the inclined portion and the horizontal plane to be in the range of 10°-20°, the bottom of most pots can be adapted, thereby reducing the problem of instability when the pot is placed on the pot support.

[0015] Preferably, the supporting legs and the heat insulating member are formed separately, and each of the supporting legs is formed in one piece.

[0016] In the present technical solution, the supporting legs and the heat insulating member are formed separately, and the supporting legs are formed in one piece, so that the manufacturing process of the pot support can be simplified, thereby reducing the manufacturing cost of the pot support.

[0017] Preferably, the inner surface shape of the heat insulating member used to accommodate the anti-dry-burning probe matches the outer surface shape of the anti-dry-burning probe.

[0018] In the present technical solution, by providing a heat insulating member to accommodate the inner surface shape of the anti-dry burning probe and matching the outer surface shape of the anti-dry burning probe, the heat insulating member can further improve its barrier effect on high-temperature flue gas near the anti-dry burning probe.

[0019] Preferably, the size of the inner surface of the thermal insulation member is set such that the inner surface of the thermal insulation member is spaced apart from the outer surface of the anti-dry-burning probe.

[0020] In the present technical solution, by setting the inner surface size of the thermal insulation member to be: the inner surface of the thermal insulation member and the outer surface of the anti-dry-burning probe are spaced apart, it can be avoided that after the thermal insulation member is heated by high-temperature flue gas, the heat is directly transferred to the outer surface of the anti-dry-burning probe, thereby affecting the sensing temperature of the anti-dry-burning probe.

[0021] Preferably, the support leg further includes a supporting portion, the supporting portion and the inclined portion are detachably connected, and the inclined portion and the thermal insulation member are integrally formed.

[0022] In the present technical solution, the support legs also include a supporting portion, and the supporting portion and the inclined portion are detachably connected, so that the user can choose whether to install the inclined portion according to the height of the bottom of the cookware, thereby expanding the range of cookware that the pot support is compatible with.

[0023] Preferably, the cross-section of the inclined portion is U-shaped, and the lower open end of the inclined portion is detachably overlapped on the upper side of the supporting portion.

[0024] In the present technical solution, by setting the cross-section of the inclined portion to be U-shaped, the lower open end of the inclined portion can be detachably overlapped on the top of the supporting portion, and a relatively simple structure can be set up so that the lower part of the inclined portion can be stably overlapped with the supporting portion.

[0025] Preferably, the anti-dry burning probe comprises a shell and a sensor sheet, and the sensor sheet is located at the top of the inner cavity of the shell.

[0026] In this technical solution, an anti-dry burning probe is provided including a shell and a sensor sheet, and the sensor sheet is located at the top of the inner cavity of the shell. The shell can further block the high-temperature smoke from affecting the sensor sheet, and ensure the sensitivity of the sensor sheet to the temperature at the bottom of the pot.

[0027] A burner comprises the pot support as described in any one of the above items.

[0028] In the present technical solution, by providing a burner including a pot support as described in any of the above items, unnecessary flameout of the burner due to the anti-dry burning probe being affected by high-temperature flue gas can be reduced, thereby improving the user experience.

[0029] The positive and progressive effects of the utility model are:

[0030] When a pot support provided by the utility model is installed on a burner, the heat insulation member arranged in the pot support can enclose the heat insulation member on the periphery of the anti-dry burning probe of the burner, thereby blocking the high-temperature flue gas and preventing the heat of the high-temperature flue gas from affecting the sensing temperature of the anti-dry burning probe and causing the problem of false alarm. Furthermore, by connecting the heat insulation member to the support foot, the temperature of the heat insulation member can be timely transmitted to the support foot with a lower temperature. Compared with the setting of connecting the heat insulation member to other relatively high-temperature structures in the burner, the technical solution can better cool the heat insulation member, further preventing the heat insulation member from being heated by the high-temperature flue gas and releasing heat to the anti-dry burning probe, thereby affecting the sensing temperature of the anti-dry burning probe. In addition, by setting the upper end of the heat insulation member to be located at or below the horizontal plane where the intersection point is located, the situation where the heat insulation member is hit by the bottom of the pot when the bottom of the pot is placed on the pot support can be reduced, and the situation where the heat insulation member is broken can be reduced. By providing a burner, which includes the above pot support, the unnecessary flameout of the burner due to the anti-dry burning probe being affected by the high-temperature flue gas can be reduced, thereby improving the user experience.

[0045] Two preferred embodiments are given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0046] Example 1

[0047] like Figure 1-Figure 4 As shown, this embodiment provides a pot support, which includes four legs 1, and the pot support also includes a heat insulation 2. When the pot support is installed on the burner, the heat insulation 2 can surround the periphery of the anti-dry burning probe 4 in the burner. In this way, the high-temperature flue gas can be blocked to prevent the heat of the high-temperature flue gas from affecting the sensing temperature of the anti-dry burning probe 4 and causing false alarms. Of course, in other embodiments, the number of legs can also be set to other numbers that can stably support the pot.

[0048] The heat insulating member 2 is located between the four legs 1, and the four legs 1 extend toward the heat insulating member 2 and are respectively connected to the heat insulating member 2. In this way, the temperature of the heat insulating member 2 can be timely transferred to the legs 1 with a lower temperature. Compared with the arrangement of connecting the heat insulating member 2 to other relatively high-temperature structures in the burner, this embodiment can better cool the heat insulating member 2, and further prevent the heat insulating member 2 from being heated by the high-temperature flue gas and releasing heat to the periphery of the anti-dry-burning probe 4, thereby affecting the temperature sensed by the anti-dry-burning probe 4.

[0049] The axes of the upper surfaces of the inclined portions 11 of the four legs 1 intersect at the same intersection 3, and the upper end of the heat insulating member 2 is located at the horizontal plane of the intersection 3. In this way, when the bottom of a pot (not shown in the figure) is placed on the pot support, the heat insulating member 2 is less likely to be hit by the bottom of the pot and break. Of course, in other embodiments, the upper end of the heat insulating member can also be set to be lower than the horizontal plane of the intersection 3.

[0050] Specifically in this embodiment, the entire pot support is formed by integrally forming the support leg 1 and the heat insulating member 2. This structural setting scheme can avoid the problem that after the support leg 1 and the heat insulating member 2 are formed separately, they will expand and contract due to heat during use, causing the connection to fall off or be overly squeezed. Of course, in other embodiments, the support leg and the heat insulating member can also be manufactured by other suitable manufacturing methods, and then combined together after the two are manufactured separately.

[0051] In this embodiment, since the support leg 1 and the heat insulating member 2 are integrally formed, the support leg 1 and the heat insulating member 2 are made of the same material, which can avoid the problem that the difference in thermal expansion coefficients of the materials of the support leg 1 and the heat insulating member 2 is too large, and the two materials are in a high temperature environment during use, causing the two to expand and contract separately, causing the connection to fall off or be excessively squeezed against each other. Of course, in other embodiments, the support leg and the heat insulating member can also be made of other materials whose difference in thermal expansion coefficients does not affect the stability of the connection.

[0052] In this embodiment, by setting the angle α between the upper surface of the inclined portion 11 and the horizontal plane to be 10°, such an angle setting can adapt to the bottom of most pots and reduce the problem of instability when the pot is placed on the pot support. Of course, in other embodiments, the angle between the upper surface of the inclined portion 11 and the horizontal plane can also take other angle ranges. Among them, if the angle between the upper surface of the inclined portion 11 and the horizontal plane is between 10°-20°, the stability of the pot placed on the pot support can also be improved.

[0053] In this embodiment, by setting the inner surface shape of the thermal insulation member 2 to accommodate the anti-dry burning probe 4 to match the outer surface shape of the anti-dry burning probe 4, the barrier effect of the thermal insulation member 2 on the high-temperature flue gas near the anti-dry burning probe 4 can be further improved.

[0054] In addition, in this embodiment, the inner surface of the heat insulating member 2 is not in direct contact with the outer surface of the anti-dry burning probe 4, that is, the inner surface of the heat insulating member 2 is spaced from the outer surface of the anti-dry burning probe 4. This spacing arrangement can prevent the heat of the heat insulating member 2 from being directly transferred to the outer surface of the anti-dry burning probe 4 after being heated by the high-temperature flue gas, thereby affecting the temperature sensed by the anti-dry burning probe 4.

[0055] Specifically in this embodiment, the anti-dry burning probe 4 includes a shell 41 and a sensor 42. The sensor 42 is located at the top of the inner cavity of the shell 41. The shell 41 can further block the high-temperature smoke from affecting the sensor 42 and ensure the sensitivity of the sensor 42 to the temperature at the bottom of the pot.

[0056] Please refer to Figure 3-Figure 4 The present embodiment also provides a burner, which includes the above pot support. By adopting this pot support, unnecessary flameout of the burner due to the anti-dry burning probe 4 being affected by high-temperature flue gas can be reduced, thereby improving the user experience.

[0057] Example 2

[0058] like Figure 5 As shown, the overall structure of the pot support and the burner of this embodiment is basically the same as that of the embodiment 1, and the main difference is that:

[0059] In this embodiment, the support legs 1 and the heat insulating member 2 are formed separately, and the support legs 1 are formed integrally, and the heat insulating member 2 is combined with the entire support legs 1 to form a pot support. This structural arrangement can make the manufacturing process of the pot support simpler, thereby reducing the manufacturing cost of the pot support.

[0060] In this embodiment, the support leg 1 further includes a support portion 12, and the support portion 12 is detachably connected to the inclined portion 11. In this way, the user can choose whether to install the inclined portion 11 according to the height of the bottom of the pot, thereby expanding the range of pots that the pot support is adapted to.

[0061] In this embodiment, by setting the cross-section of the inclined portion 11 to be U-shaped, the lower open end of the inclined portion 11 can be detachably overlapped on the top of the support portion 12, and a relatively simple structure can be set up so that the lower part of the inclined portion 11 can be stably overlapped with the support portion 12.

[0062] 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.
