As shown in fig. 5, fig. 5 is a top view of the gas range in the embodiment of the present application, and the panel 2 provides an operable platform for a user to operate conveniently.

In addition, with continued reference to fig. 1, the gas range 100 further includes a bracket 4, a liquid containing plate 5 and a knob 6. Wherein, the support 4 is a tool commonly used for supporting a pot, as shown in fig. 2, the support 4 comprises a milk pot support 41 and a energy-collecting plate pot support 42. Wherein, the milk pan support 41 is generally used for supporting a smaller milk pan, and the energy-gathering pan support 42 is generally used for supporting a larger pan. The brackets 4 are generally placed directly on the panels 2, one bracket 4 being disposed around each burner 3 on each panel 2.

As shown in fig. 2, the liquid containing plate 5 is generally an annular plate with a through hole at the center, the through hole is opposite to the burner 3 and allows flame to pass through, and the annular plate can be used for receiving soup or other sundries overflowing from the pot, so that the soup or the sundries are prevented from entering the burner 3 and causing the burner 3 to be blocked; the knob 6 is connected with a gas valve (not shown in the figure), a user can carry out ignition and control of the fire quantity through the knob 6, and the knob 6 comprises a zero-position identification knob 61 and a zero-position identification knob 62, so that different use requirements of the user can be met.

It will be understood that the gas burner also comprises other relevant components located in the installation chamber 11, for example, as shown in fig. 6, fig. 6 being a cross-sectional view taken along a-a in fig. 5, and that the gas burner 100 may also comprise a gas delivery conduit 12. Furthermore, the gas range may also comprise a gas control system, an electronic ignition component (neither shown in the figures).

Next, a burner in a gas stove according to an embodiment of the present application is further described, as shown in fig. 7, fig. 7 is an isometric view of the burner in the embodiment of the present application, and a burner 3 according to the embodiment of the present application includes a burner head 31, an inner ring fire cover 32, and a temperature sensor 33.

The inner ring fire cover 32 is mounted on the burner 31, and is of a hollow structure. In addition, as shown in fig. 9, fig. 9 is an isometric view of the inner ring fire cover 32 in the embodiment of the present application, the side wall of the inner ring fire cover 32 includes a fire blocking wall 321, a fire separating wall 322 and an inner fire wall 323 which are sequentially close to the burner head 31 (fig. 7), wherein the fire blocking wall 321 encloses a fire blocking space 324, the inner fire wall 323 is provided with a plurality of first fire holes 325, and the fire separating wall 322 connects the fire blocking wall 321 and the inner fire wall 323. The temperature sensor 33 (fig. 7) is disposed in the fire blocking space 324, and a portion of the temperature sensor 33 extends out of an end of the fire blocking wall 321 away from the burner head 31.

It will be appreciated that the gas and air are mixed within the burner 31 to form a mixed gas. Inner ring fire lid 32 is installed on furnace end 31, and inner ring fire lid 32 is hollow structure, because inner ring fire lid 32 has fire wall 321 and interior fire wall 323, fire wall 321 encloses into fire blocking space 324, a plurality of first fire holes 325 have been seted up on interior fire wall 323, temperature sensor 33 sets up in fire blocking space 324, and a part of temperature sensor 33 stretches out fire wall 321 and keeps away from the one end of furnace end 31, consequently, when the user sits the pot on support 4, flame can spout and then heat the pan from a plurality of first fire holes 325, and the bottom of pan can contact with temperature sensor 33, the temperature at the bottom of the real-time detection pot. The temperature sensor 33 is located in the fire blocking space 324, so that the flame formed at the first fire hole 325 can be prevented from influencing the temperature measurement of the temperature sensor 33, and the detection accuracy of the temperature sensor 33 can be ensured.

In addition, the side wall of the inner ring fire cover 32 in the burner provided by the embodiment of the present application further includes a fire barrier wall 322, which connects the fire barrier wall 321 and the inner fire wall 323. That is, the firestop wall 321 and the inner fire wall 323 can be separated by providing the fire partition wall 322, so that the plurality of first fire holes 325 in the inner fire wall 323 are separated from the temperature sensor 33 provided in the firestop space 324 of the firestop wall 321. Compared to the prior art in which the fire blocking wall 321 and the inner fire wall 323 are directly connected, the plurality of first fire holes 325 are relatively far away from the temperature sensor 33, and the flame has relatively less heating effect on the temperature sensor 33. From this, the design of inner ring fire lid 32 in this application has reduced flame to temperature sensor 33's heating influence, and then makes the temperature of the pan bottom that detects less with actual pan bottom temperature deviation, has improved the degree of accuracy that the bottom of a boiler temperature detected.

Thus, when the gas stove 100 with the burner 3 is used for boiling water or oil, the design of the inner ring fire cover 32 can greatly reduce the heating influence of flame on the temperature sensor 33, so that the temperature sensed by the temperature sensor 33 is closer to the actual temperature of the bottom of the pot, and further, whether the oil temperature in the pot is dry or not in the oil boiling process or whether the oil temperature reaches the oil or not in the water boiling process can be accurately monitored in real time.

In some embodiments, referring to fig. 8, the combustor 3 may further include an outer ring fire cover 34 and an air distributor 35, wherein the outer ring fire cover 34 is disposed around the outer side of the inner ring fire cover 32. As shown in fig. 10, fig. 10 is an exploded view of the outer ring fire cover 34 and the gas distributor 35 according to the embodiment of the present disclosure, the outer ring fire cover 34 includes a first outer ring side wall 341, a first inner ring side wall 342, and a first top wall 343 connecting the first outer ring side wall 341 and the first inner ring side wall 342, and a plurality of second fire holes 344 are opened on the first top wall 343 along a direction perpendicular to the first top wall 343. The second fire holes 344 may be vertically upwardly disposed to increase a contact area of the flame with the bottom of the pot, thereby improving heating efficiency.

As shown in fig. 8, the gas distribution plate 35 is located above the burner 31, the outer ring fire cover 34 is located above the gas distribution plate 35, and the gas distribution plate 35 and the outer ring fire cover 34 enclose a gas distribution chamber 351 (see fig. 10) for communicating with the burner 31, so that the second fire holes 344 (see fig. 10) on the outer ring fire cover 34 communicate with the burner 31 and can uniformly discharge gas.

It should be noted that, as shown in fig. 7, the outer ring fire cover 34 and the inner ring fire cover 32 are arranged at an interval, so that the inner ring fire cover 32 supplements the secondary air to make it fully burn. The space between the outer ring cap 34 and the inner ring cap 32 may be used to mount a thermocouple, an ignition pin, etc. (not shown) to make full use of the limited space of the burner 3. In addition, the outer ring fire cover 34 and the inner ring fire cover 32 which are arranged in a split mode are simple in structure, low-cost and large-scale production is facilitated, and the competitiveness of products is improved.

As shown in FIG. 9, in some embodiments, the outer surface of the fire barrier 322 is beveled. Wherein, the end of the fire partition wall 322 connected with the fire blocking wall 321 is a first opening 326, and the end of the fire partition wall 322 connected with the inner fire wall 323 is a second opening 327. Wherein the opening size of the first opening 326 is smaller than the opening size of the second opening 327. Therefore, by setting the outer surface of the fire wall 322 to be an inclined surface and making the first opening 326 of the fire wall 322 smaller than the second opening 327 of the fire wall 322, the distance between the first fire hole 325 and the temperature sensor 33 (see fig. 7) in the axial direction of the inner ring fire cover 32 is increased, and the distance between the first fire hole 325 and the temperature sensor 33 in the radial direction of the inner ring fire cover 32 is also increased, so that the thermal influence of the flame sprayed from the first fire hole 325 on the temperature sensor 33 is greatly reduced.

With continued reference to fig. 9, in some embodiments, the outer surface of the inner fire wall 323 is also beveled. Wherein, one end of the inner fire wall 323 far away from the fire separating wall 322 is provided with a third opening 328. Wherein the opening size of the second opening 327 is smaller than the opening size of the third opening 328. Thus, by providing the outer surface of the fire wall 323 as a slope, and making the second opening 327 of the fire wall 322 smaller than the opening of the fire wall 323 at the end away from the fire wall 322, it is equivalent to the opening of the fire wall 323 at the end close to the fire wall 322 smaller than the opening of the fire wall 323 at the end away from the fire wall 322. Thus, the distance between the first fire hole 325 and the temperature sensor 33 (see fig. 7) in the radial direction and the axial direction of the inner ring fire cover 32 is further increased, and the thermal influence of the flame jetted from the first fire hole 325 on the temperature sensor 33 is further reduced.

It is understood that the size of the opening dimension may be interpreted as the size of the diameter if the opening is circular; if the opening is square, the size of the opening is the size of the side length; if the opening is in other irregular shapes, the size of the opening is the average length of the side length.

With continued reference to FIG. 9, in some embodiments, the first fire holes 325 are circular holes and the axis of the first fire holes 325 extends perpendicular to the outer surface of the inner fire wall 323. Therefore, when the first fire hole 325 is made by using the drill, the outer surface of the inner fire wall 323 where the first fire hole 325 is located is drilled perpendicularly, and the situation that the fire hole is deflected and the drill is broken is not easy to occur. In addition, because the extension direction of the axis of the first fire hole 325 is vertical to the outer surface of the inner fire wall 323, the length of the first fire hole 325 in the inner fire wall 323 is shortest, and the length of the outer flame of the flame sprayed out from the first fire hole 325 is longest, so that the flame sprayed out from the fire hole is easier to burn to the bottom of the pan, and the heating efficiency is higher. Moreover, since the second fire holes 344 (fig. 10) are vertically upward and the first fire holes 325 are obliquely arranged, the second fire holes 344 and the flames of the first fire holes 325 do not intersect in a normal combustion state, so that the combustion is more sufficient, and the content of carbon monoxide generated due to insufficient combustion is reduced.

With continued reference to fig. 9, to further increase the distance between the first fire holes 325 and the temperature sensor 33 (see fig. 7) in the radial and axial directions of the inner ring fire cover 32, in some embodiments, the first fire holes 325 are disposed at an end of the inner fire wall 323 remote from the fire wall 322. That is, the first fire holes 325 are selectively formed at the end of the inner fire wall 323 away from the fire wall 322 when the inner fire wall 323 is formed. This can further reduce the influence of the flame emitted from the first flame holes 325 on the heat of the temperature sensor 33.

As shown in fig. 11, fig. 11 is a top view of the inner ring fire cover 32 in the embodiment of the present application, and in some embodiments, the plurality of first fire holes 325 includes a plurality of first auxiliary fire holes 3251 and a plurality of first main fire holes 3252, the plurality of first auxiliary fire holes 3251 are disposed around the inner fire wall 323, the plurality of first main fire holes 3252 are disposed on a side of the plurality of first auxiliary fire holes 3251 away from the fire partition wall 322, and the plurality of first main fire holes 3252 are disposed around the plurality of first auxiliary fire holes 3251. Wherein the plurality of first auxiliary fire holes 3251 has a smaller aperture than the plurality of first main fire holes 3252.

Based on this, since the distance between the plurality of first auxiliary fire holes 3251 and the temperature sensor 33 (see fig. 7) in the radial and axial directions of the inner ring fire cover 32 is smaller than the distance between the plurality of first main fire holes 3252 and the temperature sensor 33 in the radial and axial directions of the inner ring fire cover 32, in the present embodiment, the diameter of the plurality of first auxiliary fire holes 3251 is set smaller than that of the plurality of first main fire holes 3252, so that the length of flames emitted from the plurality of first auxiliary fire holes 3251 is smaller than that of flames emitted from the plurality of first main fire holes 3252. Thus, although the distance between the plurality of first auxiliary fire holes 3251 and the temperature sensor 33 in the radial and axial directions of the inner ring fire cover 32 is smaller than the distance between the plurality of first main fire holes 3252 and the temperature sensor 33 in the radial and axial directions of the inner ring fire cover 32, the flames emitted from the plurality of first auxiliary fire holes 3251 do not have a large heating effect on the temperature sensor 33, and the heating effect of the flames on the temperature sensor 33 is reduced while the thermal efficiency of the burner 3 is improved.

Thus, as shown in FIG. 12, FIG. 12 is a front view of the inner ring fire cover 32 in the embodiment of the present application, and in some embodiments of the present application, the shortest distance h1 between the end of the fire blocking wall 321 away from the burner 31 and the end of the fire blocking wall 321 close to the burner 31 (see FIG. 7) is 15mm to 25 mm. That is, the height h1 of the firestop wall 321 is set to 15 to 25mm, and the height h1 may be 15mm, 20mm or 25mm, preferably 20 mm. Therefore, the tightness of wrapping the temperature sensor 33 (see fig. 7) by the fire-blocking wall 321 is improved, the flame of the inner ring fire cover 32 is prevented from heating the temperature sensor 33, and the deviation between the induction pan bottom temperature of the temperature sensor 33 and the actual pan bottom temperature is small.

When the height of the fire blocking wall 321 is smaller than the value range, the fire blocking wall 321 is short and small, the appearance effect is not obvious, the fire blocking wall only plays a role in structural support and auxiliary secondary air channel, the effect is not good in the aspect of isolating the flame of the inner ring fire cover 32, therefore, the temperature sensor 33 is greatly influenced by the heating of the flame of the inner ring fire cover 32, and the deviation between the temperature of the pot bottom sensed by the temperature sensor 33 and the actual pot bottom temperature is large. When the height of the fire blocking wall 321 is greater than the above value range, the temperature sensor may not extend out of the top of the fire blocking wall 321 and contact the bottom of the pot to measure the temperature.

To further ensure the tightness of the fire wall 321 around the temperature sensor 33, as shown in FIG. 11, in some embodiments, the fire wall 321 has an outer diameter d5 of 20-30 mm, and illustratively, the outer diameter d5 may be 20mm, 25mm, or 30mm, and preferably 25 mm. The fire wall 321 has an inner diameter d6 of 15-25 mm, and illustratively, the inner diameter d6 may be 15mm, 20mm, or 25mm, and preferably 20 mm.

Since the temperature sensor 33 is used for detecting the temperature of the bottom of the pot, in order to ensure the accuracy of the detection result, the top of the temperature sensor 33 is generally arranged to be in contact with the bottom of the pot, and therefore, as shown in fig. 13, under the condition that the pot is not made, the height of the top of the temperature sensor 33 is higher than that of the top of the support 4, and the distance from the top of the temperature sensor 33 to the top of the support 4 is h 5. In addition, as shown in fig. 14, the temperature sensor 33 includes a temperature sensing probe and a telescopic spring (neither shown in the figure), so that the temperature sensor 33 has a compression stroke, and the distance h6 between the top of the fire wall 321 and the top of the bracket 4 is set to be 5-15 mm, for example, the distance h6 may be 5mm, 10mm, 15mm, and preferably 10mm, so as to ensure that the temperature sensor 33 does not reach the limit compression position when the top of the temperature sensor 33 is compressed to the top of the fire wall 321.

Based on this, in abnormal situation, when the user uses the sharp-bottomed pot to compress the temperature sensor 33, the distance h6 (see fig. 14) between the top end of the fire-blocking wall 321 and the top of the bracket 4 can ensure that the temperature sensor 33 still does not reach the extreme compression position when the pot bottom contacts the top of the fire-blocking wall 321, thereby protecting the temperature sensor 33 from being damaged by hard contact force. In addition, when the user moves the pot and puts down the pot, the temperature sensor 33 will swing back and forth under the force in the horizontal direction, and when the force in the horizontal direction of the temperature sensor 33 is too large, the inner diameter d6 (see fig. 11) of the fire blocking wall 321 and the distance h6 (see fig. 14) between the top of the fire blocking wall 321 and the top of the bracket 4 can ensure that the temperature sensor 33 transmits the external force to the fire blocking wall 321, so that the external force is transmitted to the whole gas stove 100, and the temperature sensor 33 is prevented from being damaged.

In order to increase the flame coverage area of the inner flame cover 32 of the burner 3 and ensure that the flame of the inner flame cover 32 has a small heating effect on the temperature sensor 33, as shown in fig. 12, in some embodiments, the flame blocking wall 321 is circular (see fig. 11), and the included angle a1 formed between the outer surface of the inner flame wall 323 and the axis of the flame blocking wall 321 is 30 ° to 45 °, exemplarily, the included angle a1 may be 30 °, 40 °, 45 °, and is preferably 37 °. That is, in the case where the axial direction of the inner ring fire cover 32 is arranged in the vertical direction, the angle a1 between the outer surface of the inner fire wall 323 and the vertical direction is set to 30 ° to 45 °, and preferably 37 ° here. So for the flame of inner ring fire lid 32 is far away from temperature sensor 33 (see fig. 7), thereby guaranteeing the pan bottom thermally equivalent, when increasing the coverage area of flame, it is less to the heating influence of temperature sensor 33 to have guaranteed the flame of inner ring fire lid 32.

As shown in fig. 11, in some embodiments, the first auxiliary fire holes 3251 have a diameter of 1.7mm to 2mm, and illustratively, the first auxiliary fire holes 3251 may have a diameter of 1.7mm, 1.9mm, or 2mm, and preferably 1.9mm, and the first main fire holes 3252 have a diameter of 2.1mm to 2.5mm, and illustratively, the first main fire holes 3252 may have a diameter of 2.1mm, 2.3mm, or 2.5mm, and preferably 2.3 mm. When the aperture of the first auxiliary fire hole 3251 is smaller than 1.7mm or the aperture of the first main fire hole 3252 is smaller than 2.1mm, the length of the outer flame sprayed out of the fire hole is short, and the outer flame is not easy to burn to the bottom of the pot, so that the combustion efficiency of the combustor 3 is low; on the other hand, when the diameter of the first auxiliary fire hole 3251 is greater than 2mm or the diameter of the first main fire hole 3252 is greater than 2.5mm, the length of the outer flame emitted from the fire hole is long, which causes a large heating effect on the temperature sensor 33 (see fig. 7).

Therefore, in some embodiments of the present application, the aperture of the first auxiliary fire hole 3251 is set to 1.7mm to 2mm, preferably 1.9mm herein, and the aperture of the first main fire hole 3252 is set to 2.1mm to 2.5mm, preferably 2.3mm herein, so that the flame emitted from the inner ring fire cover 32 can ensure both the combustion efficiency of the burner 3 and the temperature sensor 33 to be less affected by the heating of the flame.

To further ensure the heat insulation effect of the fire blocking wall 321, as shown in fig. 12, in some embodiments, the height h2 of the first auxiliary fire holes from the top end of the fire blocking wall 321 is set to be 22-28 mm, illustratively, h2 may be set to be 22mm, 25mm, 28mm, the height h3 of the first main fire holes from the top end of the fire blocking wall 321 is set to be 26-32 mm, illustratively, h3 may be set to be 26mm, 30mm, 32mm, the thickness h4 (see fig. 15) of the inner fire wall 323 is set to be 2.5-3.5 mm, and illustratively, h4 may be set to be 2.5mm, 3.0mm, 3.5 mm. Thus, the fire holes are formed at a sufficient height from the top end of the fire blocking wall 321 in the axial direction of the inner ring fire cover 32, so that the flames emitted from the inner fire wall 323 are sufficiently blocked by the fire blocking wall 321, and the heat insulation effect of the fire blocking wall 321 can be ensured.

Preferably, the height h2 of the first auxiliary fire holes from the top end of the fire blocking wall 321 is set to 25mm, the height h3 of the first main fire holes from the top end of the fire blocking wall 321 is set to 28mm, and the thickness h4 of the inner fire wall 323 is set to 3 mm.

Also to further ensure the thermal insulation of the firestop wall 321, as shown in FIG. 11, in some embodiments, the plurality of first auxiliary fire holes may have a diameter of 38-42 mm around the inner fire wall 323, for example, the plurality of first auxiliary fire holes may have a diameter of 38-42 mm around the inner fire wall 323, that is, the plurality of first auxiliary fire holes may have a circular ring-shaped structure with a diameter of 38-42 mm, the plurality of first main fire holes may have a diameter of 43-46 mm around the inner fire wall 323, for example, the plurality of first main fire holes may have a diameter of 43-46 mm around the inner fire wall 323, that is, the plurality of first main fire holes may have a circular ring-shaped structure with a diameter of 43-46 mm. Thus, the fire holes are spaced far enough from the top end of the fire blocking wall 321 in the radial direction of the inner ring fire cover 32, so that the flames sprayed from the inner fire wall 323 can be blocked by the fire blocking wall 321, and the heat insulation effect of the fire blocking wall 321 can be ensured.

Preferably, the plurality of first auxiliary fire holes has a diameter of 40mm around the inner fire wall 323, and the plurality of first main fire holes has a diameter of 44mm around the inner fire wall 323.

The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present application should be covered within the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
