Description

Central fire cover of gas stove

Technical Field

The utility model relates to a household gas cooker, in particular to a central fire cover of a gas cooker.

Background

The basic structure of the central fire cover of the existing gas stove comprises a cylinder body and an end cap arranged on or integrally formed on the cylinder body, wherein the peripheral wall of the cylinder body is provided with fire holes, and the end cap is arranged substantially horizontally. In the process of cooking or cleaning a pot, overflowing soup or pot bottom water easily drops above the end cap along the pot bottom and then diffuses outwards to possibly block the fire hole, so that the gas stove is not ignited when the blocked fire hole corresponds to the position near the ignition needle, and the gas stove cannot maintain flame when the blocked fire hole corresponds to the position near the thermocouple (or the ion induction needle with the same function). The structure is mainly characterized in that the upper surface of an inner ring fire cover in a traditional single ring fire cover or two fire covers of an inner ring and an outer ring is flat, or a section of plane at the center and an outward inclined plane at a section of inclined plane at the outer ring are added, or the whole surface of the inner ring fire cover is of a structure with a convex middle part and a high outer ring, and when water at the bottom of a pot or oil stain at the bottom of the pot drips on the surface of the fire cover and accumulates to a certain extent to break through the surface tension, the water or the oil stain can be guided to flame holes along any direction of the fire cover.

The chinese utility model patent application with application number 201010135138.4 discloses "a gas-cooker center fire lid and applied the combustor that has this center fire lid" (application publication number is CN101832560A), and the top surface of end cap has the retaining ring that restricts overflow liquid overflow all around the edge in this application to, an opening that guides overflow liquid outflow is seted up to this retaining ring. However, in the practical application process, the overflow liquid part flowing out from the opening still passes through the fire hole along the lower edge, so that the possibility of blockage exists, and the problem of blockage of the fire hole cannot be thoroughly solved. The chinese utility model patent application with application number cn201710281728.x discloses prevent blockking up central fire lid and use the combustor that has this central fire lid, adopts the flange structure, makes the overflow liquid dodge the fire hole, but its structure and processing are comparatively complicated.

Disclosure of Invention

The utility model aims to solve the technical problem that the central fire lid of gas-cooker that provides a prevent water blocking to foretell technical situation, and structure, processing are simple.

In order to achieve the above purpose, the utility model adopts the following technical scheme to realize. A central fire cover of a gas stove is characterized in that an air inlet end is arranged below the central fire cover, fire holes are formed in the peripheral wall of the cover body, a check ring for limiting overflow liquid from overflowing is arranged on the top surface of the cover body around the edge, a flow guide opening for guiding the overflow liquid to flow out is formed in the check ring, a flow guide groove is formed in the flow guide opening and is an inclined groove inclining to the peripheral wall from the top surface of the cover body, and the flow guide groove is located between every two adjacent fire holes.

Furthermore, the included angle between the diversion trench and the peripheral wall of the cover body is 20-45 degrees.

Further, the width of water conservancy diversion opening is 4 mm.

Further, the width of guiding gutter is 0.8 mm.

Further, the fire holes are flat holes.

Furthermore, the fire holes are inclined holes from inside to outside and from bottom to top. The peripheral wall of the cover body is also provided with a fire hole which is a flat hole. When the flame sprayed from the fire hole is far away from the outer ring fire cover, the transverse flame sprayed from the ignition hole can ignite the outer ring fire cover of the stove. The inner cavity of the cover body is provided with a gas distribution table integrated with the top surface of the cover body, so that the gas flow rate of the ignition hole is reduced.

Furthermore, the lower end of the peripheral wall of the cover body is also provided with a flame stabilizing hole.

Furthermore, the peripheral wall of the lower end of the cover body is also provided with a positioning groove, so that the diversion opening avoids the ignition needle and the thermocouple, the pollution of overflow to the ignition needle and the thermocouple is prevented, and the service life and the working stability are higher.

Compared with the prior art, the utility model discloses a central fire lid of waterproof stifled gas-cooker simple structure, the lid top surface sets up the retaining ring, prevents that overflow water circumference from overflowing all around, sets up water conservancy diversion opening guide water flow direction, and the water conservancy diversion opening sets up the guiding gutter, and when lid top surface ponding, the tension of ponding can also be destroyed to the water conservancy diversion opening, and ponding can flow to the flourishing liquid tray of cooking utensils along the guiding gutter of slant setting, avoids flowing to fire hole and central fire lid inner chamber, guarantees the normal function of combustor and burning. The diversion opening and the diversion trench are simple to process.
