Description

TECHNICAL FIELD

[0001] The present application relates to the field of kitchen utensils, in particular to a temperature sensing probe, a burner and a stove. BACKGROUND

[0002] At present, in order to prevent dry burning of gas stoves, a dry burning prevention temperature sensing probe is generally provided to prevent dry burning from occurring and reduce safety hazards. In the process of cooking food using a burner, the dry burning prevention temperature sensing probe directly contacts the bottom of a pot. When the temperature of the bottom of the pot reaches a preset dry burning prevention temperature, the dry burning prevention temperature sensing probe sends a signal to cut off the gas source of the burner and extinguish the burner, thereby preventing the phenomenon of dry burning from occurring.

[0003] However, the burner provided with the dry burning prevention temperature sensing probe, especially the down-draft burner, has the following three disadvantages:

[0004] 1. The high-temperature flue gas generated during combustion of the burner affects the temperature detection of the temperature sensing probe, leading to a dry burning misjudgment;

[0005] 2. The temperature sensing probe is directly installed in communication with the bottom plate. Overflowed liquid during cooking is prone to flow into the bottom plate, polluting the cabinet. Moreover, the overflowed liquid directly flows onto the inner ring flame cover, polluting the inner ring flame cover;

[0006] 3. The secondary air in the central hole of the temperature sensing probe diffuses upward in a free state, and the supplementary air is not efficient enough. SUMMARY

[0007] The present application aims to solve the above-mentioned problems of the prior art and provide a temperature sensing probe, a burner and a stove.

[0023] In the scheme, the shielding plate is provided with an annular partition plate, which can be more beneficial to heat insulation of the temperature sensing element and prevent the temperature sensing element from misjudgment.

[0024] A burner comprises a burner head and a temperature sensing probe as described above, the temperature sensing probe is vertically movably inserted into the burner head.

[0025] In this scheme, the temperature sensing probe of the burner is provided with a shielding plate, which can block the overflow liquid above the temperature sensing probe, avoiding the overflow liquid from the temperature sensing probe above flowing along the temperature sensing probe to the bottom plate of the burner; at the same time, the shielding plate can shield the inner ring fire cover of the burner, avoiding the overflow liquid directly flowing to the inner ring fire cover, so that the anti-blocking structure on the inner ring fire cover can be reduced, which not only reduces the cost of the fire cover but also achieves good anti-blocking effect; further, the shielding plate also shields the temperature sensing element at the upper end of the temperature sensing probe, avoiding the high-temperature flue gas generated by the flame of the fire cover of the burner directly rising to contact the temperature sensing element, causing the temperature sensing element to detect rapid temperature rise, leading to dry burning misjudgment; at the same time, the shielding plate and the inner ring fire cover can also form a secondary air channel, which can better adapt to the supplementing demand of secondary air.

[0026] Preferably, the center of the burner head is provided with a vertically penetrating central channel, the temperature sensing probe is vertically movably inserted into the central channel, and the shielding plate is located above the central channel.

[0030] In this scheme, the outer diameter of the shielding plate is 4-8mm larger than the outer diameter of the inner ring fire cover, so that the overflow liquid can be prevented from flowing to the inner ring fire cover to block the fire hole, and it can also be ensured that the shielding plate will not shield the flame of the inner ring fire cover or the inner ring fire cover and the outer ring fire cover contact the secondary air.

[0031] Preferably, the burner further comprises a mounting seat, and the mounting seat is arranged in the central channel.

[0036] In the scheme, the inclination angle of the mesh holes on the ring cover is smaller than the inclination angle of the fire holes of the inner ring fire cover, so that when the temperature sensing probe does not move downward, the ring cover covers the outer periphery of the inner ring fire cover, the flame of the fire holes of the inner ring fire cover is emitted from the mesh holes and the flame angle is changed, so that the flame presents an open state, the heating of the high-temperature flue gas on the temperature sensing probe is reduced, the over-heating of the temperature sensing probe caused by the folding of the flame is avoided, and the misjudgment of the temperature sensing probe is avoided, so that the dry burning condition is determined as dry burning when it is not reached, and the unexpected shutdown of the burner is caused, which is inconvenient for the user.

[0088] The application will be further described by way of example with reference to the accompanying drawings in which:

[0089] Example 1

[0090] As Figure 1As shown, the present embodiment provides a stove 100. The stove 100 is a gas appliance using natural gas or coal gas to heat a pot, which includes two burners 110 (only one of the burners 110 is shown). Alternatively, the stove 100 can also include only one burner 110 or more than three burners 110.

[0091] As shown, the burner 110 includes a burner head 111 and a temperature sensing probe 115, which is vertically movably inserted into the burner head 111. Figures 2-4

[0092] The burner head 111 has a vertically penetrating central passage 112, and the temperature sensing probe 115 is vertically movably inserted into the central passage 112, and a baffle 129 is located above the central passage 112.

[0093] The burner head 111 has a vertically penetrating central passage 112, so that secondary air can be drawn from the central passage 112.

[0094] The burner 110 is a typical down-draft burner 110, which mainly draws secondary air from below the burner 110. Since the central passage 112 penetrates to the lower part of the burner head 111, the inner ring flame cap 114 can draw secondary air from below the burner head 111 from the central passage 112.

[0095] The burner head 111 includes an outer ring flame cap 113 and an inner ring flame cap 114. The outer ring flame cap 113 is located on the outer peripheral side of the inner ring flame cap 114. The present embodiment only shows the burner head 111 with the inner ring flame cap 114 and the outer ring flame cap 113, but the temperature sensing probe 115 of the present application can also be used in a burner 110 with only an inner ring flame cap 114 or additionally with a middle ring flame cap.

[0096] The inner ring flame cap 114 is provided with a central hole 1141, which is connected to the upper end of the central passage 112, and the temperature sensing probe 115 is inserted into the central hole 1141.

[0097] The temperature sensing probe 115 includes a cylindrical shell 117, a temperature sensing element 123, a support rod 125, and a baffle 129.

[0098] The temperature sensing element 123 is located at the upper end of the shell 117, the support rod 125 is connected below the temperature sensing element 123, and the baffle 129 is sleeved on the shell 117 and extends from the shell 117 towards the outer peripheral side of the shell 117.

[0099] ​The temperature sensing probe 115 is provided with a shielding plate 129, which can shield the overflow liquid above the temperature sensing probe 115, so as to avoid the overflow liquid from the above of the temperature sensing probe 115 flowing along the temperature sensing probe 115 to the bottom plate of the burner 110; at the same time, the shielding plate 129 can shield the inner ring flame cover 114 of the burner 110, so as to avoid the overflow liquid directly flowing to the inner ring flame cover 114, so that the anti-blocking structure on the inner ring flame cover 114 can be reduced, which not only reduces the cost of the flame cover but also achieves good anti-blocking effect; further, the shielding plate 129 also shields the temperature sensing element 123 at the upper end of the temperature sensing probe 115, so as to avoid the high-temperature flue gas generated by the flame of the flame cover of the burner 110 directly rising to contact the temperature sensing element 123, which causes the temperature sensing element 123 to detect rapid temperature rise, resulting in dry burning misjudgment; at the same time, the shielding plate 129 and the inner ring flame cover 114 can also form a secondary air passage 131, which can better adapt to the supplementing demand of the secondary air.

[0100] The outer peripheral edge of the shielding plate 129 is inclined downward and to the outer peripheral side of the outer shell 117.

[0101] The outer peripheral edge of the shielding plate 129 is inclined downward and to the outer peripheral side of the outer shell 117, forming a flow guide edge, so as to avoid the overflow liquid accumulating in the center of the shielding plate 129 and being guided to the space between the inner ring flame cover 114 and the outer ring flame cover 113, which will not pollute the inner ring flame cover 114 or the central passage 112 in the center of the burner head 111.

[0102] The shielding plate 129 is arranged at the upper portion of the outer shell 117. The shielding plate 129 arranged at the upper portion of the outer shell 117 can better play a shielding role.

[0103] The outer shell 117 comprises an inner layer 121 and an outer layer 119 sleeved on the outer periphery of the inner layer 121, and the inner layer 121 and the outer layer 119 have a space therebetween.

[0104] The outer shell 117 is arranged in a double-layer structure, which is beneficial to better heat insulation and preventing the temperature sensing probe 115 from misjudgment.

[0105] Alternatively, the outer shell 117 can also be a single-layer structure.

[0106] The shielding plate 129 is threadedly connected to the outer shell 117. The outer layer 119 of the outer shell 117 is provided with external threads, and the shielding plate 129 is provided with internal threads, so that the two are threadedly engaged. The shielding plate 129 is threadedly connected to the outer shell 117, which is convenient for assembling the shielding plate 129.

[0107] The outer diameter of the shielding plate 129 is 4-8mm larger than the outer diameter of the inner ring fire cover 114. The outer diameter of the shielding plate 129 is 4-8mm larger than the outer diameter of the inner ring fire cover 114, so that the overflow liquid can be prevented from flowing to the inner ring fire cover 114 to block the fire hole, and the flame of the inner ring fire cover 114 or the contact between the inner ring fire cover 114 and the outer ring fire cover 113 can be ensured not to be shielded.

[0108] The shielding plate 129 is preferably a light and thin metal structure, which is threadedly connected to the probe. The structure is simple and low in cost, but can achieve multiple unexpected effects.

[0109] 1. The shielding plate 129 shields the central hole 1141 of the inner ring fire cover 114 and the central passage 112 of the burner head 111, so that the cooking overflow liquid is prevented from easily flowing into the bottom plate of the stove 100 to contaminate the cabinet.

[0110] 2. At the same time, the outer peripheral edge of the shielding plate 129 extends beyond the outer peripheral edge of the inner ring fire cover 114 (preferably by 2-4mm on one side), so that the overflow liquid is prevented from directly flowing to the inner ring fire cover 114, which can prevent the fire hole from being blocked and reduce the cost (reduce the setting of the anti-blocking shielding on the inner ring fire cover 114).

[0111] 3. At the same time, when there is no pot, the shielding plate 129 can play a role in fire suppression (the flame is spread outward under the action of the shielding plate 129 instead of being gathered) and shielding, which can effectively improve the misjudgment of turning off the fire caused by high-temperature flue gas.

[0112] 4. The upper surfaces of the shielding plate 129 and the inner ring fire cover 114 form a secondary air passage 131, which can direct the secondary air in the central passage 112 of the burner head 111 to the flame, so that the secondary air supplementing effect is better. The secondary air passage 131 can be different with the different distances of the temperature sensing probe 115 being pressed down, which can better adapt to the supplementing demand of the secondary air. When the temperature sensing probe 115 is pressed down to the bottom, the height of the secondary air passage 131 is greater than or equal to 3mm (the minimum secondary air passage 131).

[0113] 5. The shielding plate 129 is preferably a light and thin metal structure, which is threadedly connected to the probe. The threaded connection has the advantage of adjustable height, which can adapt to the height requirements of various burners 110, and has better adaptability. Preferably, when the temperature sensing probe 115 is pressed down to the bottom, the distance between the shielding plate 129 and the upper surface of the inner ring fire cover 114 is 3mm.

[0114] The burner 110 further comprises a mounting seat 135 arranged in the central passage 112; the temperature sensing probe 115 further comprises a spring 127 sleeved on the support rod 125; the temperature sensing probe 115 is mounted on the mounting seat 135, the lower end of the outer shell 117 is sleeved on the upper end of the mounting seat 135, the support rod 125 is vertically movably inserted into the mounting seat 135, and the spring 127 abuts between the temperature sensing element 123 and the upper end of the mounting seat 135.

[0115] When a cookware is placed on the burner 110, the temperature sensing element 123 contacts the bottom of the cookware, and the entire temperature sensing probe 115 is pressed downwards, thereby moving downwards. Specifically, the outer shell 117 of the temperature sensing probe 115 moves downwards, and the spring 127 is compressed. When the cookware is removed from the burner 110, the temperature sensing probe 115 moves upwards under the action of the spring 127.

[0116] Example 2

[0117] like Figures 5-6 As shown, this embodiment provides a burner 210, the structure of which is roughly the same as that of the burner 110 in Embodiment 1, except that:

[0118] The heat sensor shield 229 of the burner 210 includes a disc-shaped body 2291 and an annular partition 2292 erected on the upper surface of the disc-shaped body 2291.

[0119] The shield 229 is provided with an annular partition 2292, which can better insulate the temperature sensing element and avoid misjudgment by the temperature sensing element.

[0120] The lower edge of the annular baffle 2292 is connected to the disc-shaped body 2291. Alternatively, flow guide holes can be started at the lower edge of the annular baffle 2292 to prevent liquid from accumulating inside the annular baffle 2292.

[0121] In this embodiment, the annular partition 2292 is circular. Alternatively, the annular partition 2292 can also be square, rhomboid, or other shapes.

[0122] The temperature sensor is equipped with a baffle plate 229, which can block the overflow from above the temperature sensor, preventing the overflow from flowing down the sensor to the chassis of the burner 210. At the same time, the baffle plate 229 can cover the inner ring burner cap of the burner 210, preventing the overflow from flowing directly to the inner ring burner cap. This reduces the number of anti-clogging structures on the inner ring burner cap, reducing the cost of the burner cap while achieving a good anti-clogging effect. Furthermore, the baffle plate 229 also covers the temperature sensing element at the top of the temperature sensor, preventing the high-temperature flue gas generated by the flame of the burner cap on the burner 210 from directly rising and contacting the temperature sensing element, which would cause the temperature sensing element to detect a rapid temperature rise and lead to a false dry burning judgment. At the same time, a secondary air channel can be formed between the baffle plate 229 and the inner ring burner cap, which can better meet the needs of secondary air replenishment.

[0123] Example 3

[0124] like Figure 7 As shown, this embodiment provides a burner 310, the structure of which is generally the same as that of the burner 110 in Embodiment 1, except that:

[0125] A step surface 311 is provided on the outer peripheral wall of the outer shell of the temperature sensing probe of the burner 310, and the shielding plate 329 is placed on the step surface 311.

[0126] The shielding plate is directly placed, and it is more convenient to replace and clean.

[0127] Embodiment 4

[0128] As shown in Figures 8-9 The present embodiment provides a burner 410, which has substantially the same structure as the burner 110 of Embodiment 1, except that:

[0129] The shielding plate 413 of the temperature sensing probe of the burner 410 includes a disc-shaped body 415 and a ring-shaped cover 416 connected to the lower part of the disc-shaped body 415, the ring-shaped cover 416 covers the outer periphery of the inner ring flame cap 411, and a plurality of mesh holes 417 corresponding to the flame holes 4111 of the inner ring flame cap 411 are provided on the ring-shaped cover 416, the inclination angle of the mesh holes 417 is smaller than the inclination angle of the flame holes 4111 of the inner ring flame cap 411. The mesh holes 417 of the ring-shaped cover 416 and the flame holes 4111 of the inner ring flame cap 411 are preferably in one-to-one correspondence, i.e., the same position and the same number.

[0130] Here, the "inclination angle" refers to the angle between the axis of the mesh hole 417 and the flame hole 4111 and the horizontal surface, and the horizontal surface is perpendicular to the central axis of the flame cap of the burner 410. Generally, the tabletop of the stove is the horizontal surface.

[0131] In the present embodiment, the disc-shaped body 415 and the ring-shaped cover 416 are connected by a connecting plate 418. The length of the connecting plate 418 is set such that when the pot is not placed on the burner 410, i.e., the temperature sensing probe is not pressed down, the ring-shaped cover 416 just covers the outer periphery of the inner ring flame cap 411. A gap is left between the ring-shaped cover 416 and the inner ring flame cap 411 to avoid interference when the ring-shaped cover 416 moves relative to the inner ring flame cap 411.

[0132] A plurality of perforations 419 are also provided on the connecting plate 418, and the number and position of the perforations 419 correspond to the position and number of the flame holes 4111 of the inner ring flame cap 411 opposite to the connecting plate 418 in the circumferential direction, so that when the temperature sensing probe is pressed down, the flame holes 4111 of the inner ring flame cap 411 are not shielded, and the inclination angle of the perforations 419 can be consistent with the inclination angle of the flame holes 4111 of the inner ring flame cap 411.

[0133] Alternatively, the annular cover 416 and the disc-shaped body 415 can be connected by a plurality of thin rods instead of the connecting plate 418, and the thin rods are arranged at positions avoiding the fire holes 4111 of the inner ring fire cover 411 to avoid blocking the fire holes 4111 of the inner ring fire cover 411 and affecting the generation of the flame.

[0134] The inclination angle of the mesh holes 417 on the annular cover 416 is smaller than that of the fire holes 4111 of the inner ring fire cover 411, so that when the temperature sensing probe is not lowered, the annular cover 416 covers the outer periphery of the inner ring fire cover 411, the flame of the fire holes 4111 of the inner ring fire cover 411 is emitted from the mesh holes 417 and the flame angle is changed, so that the flame presents an open state, the heating of the high-temperature flue gas on the temperature sensing probe is reduced, the excessive heating of the high-temperature flue gas on the temperature sensing probe due to the folding of the flame is avoided, and the false judgment of the temperature sensing probe is avoided, so that the dry burning condition is determined as dry burning when the dry burning condition is not reached, and the unexpected shutdown of the burner 410 is avoided, which is inconvenient for the user.

[0135] The temperature sensing probe of the burner 410 is provided with a shielding plate 413, which can block the overflow liquid above the temperature sensing probe to avoid the overflow liquid from the upper part of the temperature sensing probe flowing to the bottom plate of the burner 410. At the same time, the shielding plate 413 can shield the inner ring fire cover 411 of the burner 410 to avoid the overflow liquid directly flowing to the inner ring fire cover 411. In this way, the anti-blocking structure on the inner ring fire cover 411 can be reduced, which not only reduces the cost of the fire cover but also achieves a good anti-blocking effect. Further, the shielding plate 413 also shields the temperature sensing element at the upper end of the temperature sensing probe, avoiding the high-temperature flue gas generated by the flame of the fire cover of the burner 410 directly rising to contact the temperature sensing element, which causes the temperature sensing element to detect rapid heating and causes false judgment of dry burning. At the same time, the shielding plate 413 and the inner ring fire cover 411 can form a secondary air passage, which can better meet the demand for secondary air supply.
