Technical Field

[0001] The utility model relates to a stove, in particular to an anti-dry burning stove. Background Art

[0002] Anti-dry burn stoves are a mainstream product among current stove products, with good safety. Anti-dry burn probes are the core parts of anti-dry burn stoves. The anti-dry burn probes in existing products need to touch the bottom of the pot to work, and can often only be used with flat-bottomed pots, which limits the types of pots that can be used and has great limitations. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an anti-dry-burning stove in order to overcome the defect that the anti-dry-burning stove in the prior art has great limitations on cookware.

[0004] The utility model solves the above technical problems through the following technical solutions:

[0005] A dry-burn prevention stove includes an inner ring fire cover. The stove also includes a probe-type dry-burn prevention probe, which includes a thermocouple temperature sensor. The top of the dry-burn prevention probe is lower than the top of the inner ring fire cover.

[0006] In the technical solution, a non-contact anti-dry-burning probe is provided so that the anti-dry-burning probe does not touch the bottom of the pot when in use, so that both flat pans and pointed-bottom pots can be used on the anti-dry-burning stove, thereby improving the pot adaptability of the anti-dry-burning stove. At the same time, the top of the anti-dry-burning probe is set to a height lower than the top of the inner ring fire cover, so that the anti-dry-burning probe is not easily damaged, especially when a pointed-bottom pot is used.

[0007] Preferably, the height of the top of the anti-dry burning probe is 3 mm-10 mm lower than the height of the top of the inner ring fire cover.

[0008] In the present technical solution, by setting the height of the top of the anti-dry-burning probe to be 3mm-10mm lower than the height of the top of the inner ring fire cover, the temperature measurement effect of the anti-dry-burning probe is improved, and the anti-dry-burning stove can adapt to more pots and is not easily damaged.

[0009] Preferably, the lower end of the thermocouple temperature sensor is wrapped with glass fiber or a glass fiber insulation layer.

[0010] In the technical solution, by providing glass fiber or a glass fiber insulation layer that wraps the lower end of the thermocouple temperature sensor, the thermocouple temperature sensor has good temperature measurement characteristics and is more resistant to high temperatures, thereby making the system temperature measurement performance more stable.

[0011] Preferably, the glass fiber or glass fiber insulation layer wraps the cross section of the lower end of the thermocouple temperature sensor into a racetrack shape.

[0012] In the present technical solution, by wrapping the cross-section of the lower end of the thermocouple temperature sensor into a runway shape with glass fiber or a glass fiber insulation layer, not only the anti-dry burning probe is beautiful in shape, but also the glass fiber or glass fiber insulation layer wrapped around the thermocouple sensor is relatively uniform, so that the insulation effect in all directions around the thermocouple sensor is not much different and is relatively good, thereby improving the measurement accuracy of the thermocouple temperature sensor.

[0013] Preferably, the anti-dry-burning probe comprises a shell, the thermocouple temperature sensor is accommodated in the shell, and the inner top surface of the shell is in direct contact with the top end of the thermocouple temperature sensor.

[0014] In the technical solution, the top end of the thermocouple temperature sensor is directly in contact with the inner top surface of the probe body, so that the temperature measured by the thermocouple temperature sensor is more accurate.

[0015] Preferably, the test temperature field of the anti-dry-boiling probe is a temperature field formed between the thermocouple temperature sensor and the cookware.

[0016] In the technical solution, by detecting the temperature of the temperature field formed between the thermocouple temperature sensor and the cookware, it is determined whether it is in a dry-boiling state.

[0017] Preferably, the anti-dry-burning stove also includes a probe base and a burner base, the inner ring fire cover is arranged on the top of the burner base, the probe base is fixed inside the burner base, and the probe base is provided with a fixing hole for accommodating and fixing the anti-dry-burning probe.

[0018] In the technical solution, the anti-dry-burning probe is fixed on the probe base and then the probe base is fixed inside the burner base, so that the anti-dry-burning probe can be fixed in the burner.

[0019] Preferably, the probe base includes a fixing hole for accommodating and fixing the anti-dry-burning probe, and the anti-dry-burning probe is provided with a step surface, the cross-section of the lower end of the step surface is the same as the cross-section of the fixing hole, and the anti-dry-burning probe is clamped with the probe base through the fixing hole.

[0020] In this technical solution, the cross-section of the lower end of the step surface is set to be the same as the cross-section of the fixing hole, and the shape and size of the cross-section are the same, so that the lower end of the step surface can be snapped into the fixing hole for fixation without the need for screws. The structure is simple and the installation is convenient.

[0021] Preferably, the probe base includes a plurality of mounting holes for forming a matching installation with the burner base, and the probe base is connected to the burner base at the mounting holes by screws.

[0022] In the present technical solution, a plurality of mounting holes are provided on the probe base to form a mating connection between the probe base and the burner base, so that the probe base can be connected and fixed to the burner base by screws, making the connection between the probe base and the burner base more secure.

[0023] Preferably, the number of the mounting holes is three.

[0024] In the present technical solution, three mounting holes are provided instead of two mounting holes, thereby ensuring that the probe base can be firmly fixed on the burner base without tilting. Compared with four or more mounting holes, three mounting holes are provided, which can save the screws required for installing the probe base, thereby saving installation time and making the structure simpler.

[0025] Preferably, the anti-dry burning probe is arranged at the axis center of the inner ring fire cover.

[0026] In the technical solution, by arranging the anti-dry-burning probe at the axis of the burner, the temperature field detected by the anti-dry-burning probe is closer to the combustion center, thereby improving the measurement accuracy of the temperature sensor.

[0027] The positive progressive effect of the utility model is that the anti-dry-burning stove is provided with a non-contact anti-dry-burning probe, and the anti-dry-burning probe does not touch the bottom of the pot when in use, so that both flat pans and pointed-bottom pots can be used on the anti-dry-burning stove, thereby improving the pot adaptability of the anti-dry-burning stove. At the same time, the top end of the anti-dry-burning probe is set to a height lower than the top end of the inner ring fire cover, so that the anti-dry-burning probe is not easily damaged, especially when the pointed-bottom pot is used.

[0046] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0047] like Figure 1-5 As shown, this embodiment provides an anti-dry burning stove, which includes a burner base 1, an inner ring fire cover 2, an outer ring fire cover 3, an anti-dry burning probe 4 and a probe base 5. The inner ring fire cover 2 and the outer ring fire cover 3 are installed above the burner base 1, the anti-dry burning probe 4 is fixed on the probe base 5, and the probe base 5 is fixed inside the burner base 1. The height of the top of the anti-dry burning probe 4 is lower than the height of the top of the inner ring fire cover 2. For specific structure, please refer to Figure 1 By setting the height of the top of the anti-dry-burning probe 4 to be lower than the height of the top of the inner ring fire cover 2, the anti-dry-burning probe 4 does not touch the bottom of the pot when in use, so that both flat pans and pointed bottom pots can be used on the anti-dry-burning stove, thereby improving the pot adaptability of the anti-dry-burning stove. At the same time, the top of the anti-dry-burning probe 4 is set to be lower than the height of the top of the inner ring fire cover 2, so that the anti-dry-burning probe 4 is not easily damaged, especially when using a pointed bottom pot.

[0048] Specifically, the anti-dry-burning probe 4 is a probe type anti-dry-burning probe 4, which includes a shell 42 and a thermocouple temperature sensor 41. The thermocouple temperature sensor 41 is accommodated in the shell 42, and the inner top surface of the shell 42 is in direct contact with the top of the thermocouple temperature sensor 41; the inner top surface of the shell 42 is in direct contact with the top of the thermocouple temperature sensor 41, so that the temperature measured by the thermocouple temperature sensor 41 is more accurate, thereby making the temperature detection of the anti-dry-burning probe 4 more accurate. The top of the thermocouple temperature sensor 41 is a hot end 411, and the two semiconductors of the thermocouple sensor are connected and form an angle at the hot end 411. The lower end below the hot end 411 is a cold end. The two semiconductors are arranged in parallel, and the lower end is wrapped with glass fiber 412. The glass fiber 412 wraps the lower end of the thermocouple temperature sensor 41 into a runway-shaped cross section. By wrapping the glass fiber 412 at the lower end of the thermocouple temperature sensor 41, the thermocouple temperature sensor 41 has good temperature measurement characteristics and is more resistant to high temperatures, thereby making the temperature measurement performance of the system more stable, and the glass fiber 412 wraps the lower end of the thermocouple temperature sensor 41 into a runway-shaped cross section, which not only makes the anti-dry-burning probe 4 beautiful, but also makes the glass fiber 412 wrapped around the thermocouple sensor relatively uniform, so that the insulation effect in all directions around the thermocouple sensor is not much different and is relatively good, thereby improving the measurement accuracy of the thermocouple temperature sensor 41. In other embodiments, the middle section of the thermocouple temperature sensor 41 may also be wrapped with a glass fiber insulation layer.

[0049] In this embodiment, the probe base 5 is provided with a fixing hole 501 for accommodating and fixing the anti-dry burning probe 4 and a plurality of mounting holes 502 for forming a matching installation with the burner base 1. Specifically, the end of the lower end of the shell 42 forms a step surface with the thermocouple temperature sensor 41, and the cross section of the lower end of the step surface is the same as the cross section of the fixing hole 501 on the probe base 5, that is, the shape and size of the cross section are the same, so that the lower end of the step surface can be clamped in the fixing hole 501 for fixing, without the need for screws 503 to fix, with a simple structure and convenient installation. The probe base 5 is connected to the burner base 1 at the mounting hole 502 by screws 503, so that the connection between the probe base 5 and the burner base 1 is more secure. In this embodiment, the number of mounting holes 502 is three, and in other embodiments, the number of mounting holes 502 can also be more than three.

[0050] In this embodiment, the anti-dry-burn probe 4 is arranged at the axis of the inner ring fire cover 2, and the height of the top of the anti-dry-burn probe 4 is 3mm-10mm lower than the height of the top of the inner ring fire cover 2. The test temperature field of the anti-dry-burn probe 4 is the temperature field formed between the thermocouple temperature sensor 41 and the pot. Specifically, the core temperature field of the test of the anti-dry-burn probe 4 is the axis of the inner ring fire cover 2, and the temperature field is the temperature field formed between the thermocouple temperature sensor 41 and the pot. The axis of the inner ring fire cover 2 is the axis of the flame and the center of the heat at the bottom of the pot. It can best reflect whether the pot is in a dry-burn state, thereby making the detection of the anti-dry-burn probe 4 more accurate. The height of the top of the anti-dry-burning probe 4 is 3mm-10mm lower than the height of the top of the inner ring fire cover 2. Within this range, the temperature detected by the anti-dry-burning probe 4 has a higher accuracy; when the height difference between the top of the anti-dry-burning probe 4 and the top of the inner ring fire cover 2 is less than 3mm, the bottom of the pot may touch the anti-dry-burning probe 4 when using a pointed bottom pot, causing damage to the anti-dry-burning probe 4; when the height difference between the top of the anti-dry-burning probe 4 and the top of the inner ring fire cover 2 is higher than 10mm, the temperature field detected by the anti-dry-burning probe 4 is too far from the bottom of the pot, and the detected temperature is not accurate enough.
