Technical Field

The invention relates to the field of burners, in particular to a fire cover of a stove.

Background

At present, the fire transfer structure of the burner on the market mainly transfers the flame on the inner ring fire cover to the outer surface of the outer ring fire cover through the fire transfer channel. The inner surface of the fire transfer channel is provided with a fire transfer hole for transferring flame by igniting the fire transfer hole.

Wherein, to civilian cooking utensils product, the gas pressure and the operating mode diverse in different cooking utensils user family, some user's pressure in family is high some user's pressure in family is low, and the deviation of this kind of gas pressure can lead to passing the fire hole ignition failure when passing the fire. In order to offset the pressure deviation, when the cooker is installed, the air inlet damper can be adjusted to a reasonable range in advance, however, when some users use the cooker, the gas pressure fluctuates in a short period, and the short-period fluctuation cannot be offset by adjusting the air damper, so that fire transmission easily fails when the part of users use the cooker, and the user experience is poor.

Disclosure of Invention

The invention aims to overcome the defects that a gas cooker in the prior art is easy to cause fire transmission failure due to gas pressure change and influence user experience, and provides a cooker fire cover.

The invention solves the technical problems through the following technical scheme:

The utility model provides a cooking utensils fire lid, its inside has the gas cavity, cooking utensils fire lid still has a plurality of relatively independent biography fire passageways, the passageway cross sectional area that passes the fire passageway all differs, each all be equipped with the intercommunication in passing the fire passageway the fire hole that passes the gas cavity, the aperture that passes the fire hole reduces and reduces along with the corresponding setting the passageway cross sectional area that passes the fire passageway reduces.

This outer loop fire lid of cooking utensils fire lid is through covering the biography fire passageway that sets up a plurality of not unidimensional at the fire to the size of a dimension to these biography fire passageways sets up the biography fire hole that corresponds the size, so that under the condition that corresponds different gas pressure, have at least one to pass the fire passageway and can successfully ignite under specific gas pressure, thereby ensure the biography fire success rate that this cooking utensils fire lid, effectively promoted user experience.

Meanwhile, when a plurality of fire transfer channels are arranged, if more than two of the fire transfer channels are successfully ignited and transfer fire, the fire transfer efficiency of the fire cover of the stove can be improved.

Preferably, the stove fire cover is provided with a through hole and a partition plate, the partition plate is arranged inside the through hole, and the partition plate divides a plurality of relatively independent fire transfer channels in the through hole.

this cooking utensils fire lid is through setting up perforating hole and baffle to separate a plurality of relatively independent biography fire passageways in single through-hole structure, make these pass fire passageways both keep apart relatively, can closely be close to again in space, and then reduced and set up the occupation of a plurality of biography fire passageways to cooking utensils fire lid surface space.

Preferably, the partition plate is provided along a longitudinal direction of the through-hole.

Preferably, the partition plate includes a plurality of partition plate units, and the plurality of partition plate units are connected to each other to partition the plurality of fire transfer passages in the through hole by the plurality of partition plate units.

Preferably, the stove fire cover further comprises an air inlet channel, the air inlet channel cuts through the inner surface of the through hole along a direction perpendicular to the axis of the through hole, the air inlet channel is used for communicating the gas chamber and the fire transfer channel, and the fire transfer hole is formed in the inner surface of the through hole.

Preferably, the plurality of intake passages are provided at intervals in the direction of the axis of the through hole.

Preferably, the air inlet channel completely cuts through the inner surface of the through hole along the circumferential direction of the through hole, so that a single air inlet channel can respectively supply gas to all the fire transfer channels in the through hole to serve as fire transfer holes of the fire transfer channels, and the difficulty in arranging a plurality of fire transfer channels with different sizes on the stove fire cover and arranging fire transfer holes with different sizes on the fire transfer channels is reduced.

Preferably, the through hole is cylindrical, the partition plate includes a plurality of partition plate units, and the plurality of partition plate units are connected at an axis of the through hole and circumferentially arranged with the axis of the through hole as a center.

Above-mentioned structure is through adjusting the angle that is between each baffle unit, just can simply, fast, directly change the passageway cross sectional area relation of each biography fire passageway that is enclosed by baffle and perforating hole to realize the quick adjustment to each biography fire passageway size, be convenient for processing and design.

Preferably, the width of the intake passage in the axial direction of the through hole is equal everywhere.

For the air inlet channel with complete circular cutting through holes, the determining condition influencing the size of the fire transfer holes formed by the air inlet channel is the length of the air inlet channel because the widths of the air inlet channel are equal.

Because the length dimension of the air inlet channel is in a direct proportion relation with the angle formed between the two corresponding partition plate units, namely: the bigger the angle that is between the baffle unit, then the air inlet channel that is located this biography fire passageway is just also bigger at the opening of passing the fire hole that the perforating hole surface formed, consequently, the fire hole size that passes that the air inlet channel formed is direct ratio with the passageway cross-sectional area of this biography fire passageway to reduce the design degree of difficulty of this cooking utensils fire lid by a wide margin.

Preferably, a width of the intake passage in the axial direction of the through hole decreases as a passage sectional area of the communicating fire transfer passage decreases.

The structure further reduces the size of the fire transfer holes on the fire transfer channels with smaller relative sizes so as to further enlarge the range of gas pressure which can be covered by the fire transfer channels with different sizes.

The positive progress effects of the invention are as follows:

This outer loop fire lid of cooking utensils fire lid is through covering the biography fire passageway that sets up a plurality of not unidimensional at the fire to the size of a dimension to these biography fire passageways sets up the biography fire hole that corresponds the size, so that under the condition that corresponds different gas pressure, have at least one to pass the fire passageway and can successfully ignite under specific gas pressure, thereby ensure the biography fire success rate that this cooking utensils fire lid, effectively promote user experience and feel.
