Technical Field
The utility model relates to a heat collecting cover which is applied to a kitchen range. The utility model also relates to a burner.
Background
In order to improve the heat efficiency and reduce the energy waste, many designs of heat collecting covers, energy gathering covers or heat gathering covers are proposed in the prior art. The heat collecting cover is in a closed type in order to collect combustion heat as much as possible and reduce external heat loss, so that the heat is guaranteed not to be lost as much as possible, for example, an infrared combustion stove with the heat collecting cover (the authorized bulletin number is CN 202452547U) of Chinese patent utility model patent No. 201120499069.5; another example is a Chinese patent application of 201110146286.0, namely a high-efficiency energy-saving gas heat collecting cover and a manufacturing method thereof (application publication number is CN 102788376A); china patent No. 201420630319.8, a convenient-to-detach oven rack assembly with a heat collecting cover (issued with publication No. CN 204285553U).
The structure is a closed structure, so that secondary air supply is insufficient, combustion is insufficient, a large amount of smoke is generated, and the low smoke and the heat efficiency are the same as two important performance parameters of the household gas cooker. One needs to be closed and one needs to be opened, which forms a contradiction, so that the existing design has great difficulty in meeting the requirements of heat efficiency and low smoke on the heat collection cover at the same time.
How to optimally design, research a heat collection cover can integrate the advantages of high efficiency and low smoke into a whole, and is always a target struggled by the technicians in the field.

The technical scheme adopted for solving the technical problems is as follows: the heat collecting cover of gas kitchen range includes cover body and cushion block set in the lower end of the cover body, and the cover body is in the shape of inverted cone, and has middle area for the burner or combustor to set.
The secondary air supply holes are at least provided with two rows from top to bottom, and the two rows of secondary air supply holes are staggered up and down. The secondary air supply is more complete.
The baffle plate is provided with a vent hole. The vent holes may also provide secondary air make-up.
Further, the secondary air supply hole is square, semicircular or circular, the baffle is square, semicircular or circular, and the root of the baffle is connected with the inner side of the secondary air supply hole into a whole.
At least three pot supporting feet are arranged in the circumferential direction of the upper end of the cover body, and secondary air supply holes are formed in the position, right below the pot supporting feet, of the cover body. The secondary air supply holes are arranged right below the pot support legs, so that secondary air supply is also arranged at the pot support legs, the problem that the outer fire holes of the outer ring fire cover avoid the pot support is solved, and fire can be discharged from the outer fire holes right opposite to the pot support legs; the combustion is more uniform and sufficient.
Connecting pieces are arranged on two sides of the baffle plate and are connected with the inner edge of the secondary air supply hole.
The pot support legs are four and are uniformly arranged on the cover body.
A burner comprises a burner body and a heat collecting cover, wherein the burner body is arranged in the heat collecting cover.
The burner body is provided with an outer ring fire cover, and outer fire holes are uniformly distributed on the outer ring of the outer ring fire cover.
Compared with the prior art, the utility model has the advantages that: the secondary air supply hole is designed, so that secondary air can be timely supplied in the combustion process, and the aim of low smoke is fulfilled; the baffle is protruded on the inner surface of the cover body, so that the secondary air supply quantity is not greatly influenced, meanwhile, the directional flow distribution function is realized, air enters from a gap between the baffle and the inner edge of the secondary air supply hole, the secondary air supply is comprehensive, the secondary air supply of each part of the flame combustion of the burner can be ensured in a very short time, the combustion is ensured to be more sufficient, and the flue gas is lower; on the other hand, the baffle plate can reduce the outward loss of heat through the secondary supply hole, the baffle plate plays a role in well isolating heat from radiating heat, the baffle plate comprehensively contacts secondary air, and when the secondary air is supplied from the outside and passes through the baffle plate, the baffle plate can heat the secondary air, so that the heat efficiency is improved; the whole set of heat collecting cover has the advantages of simple structure, attractive appearance, high heat efficiency, full and comprehensive secondary air supply and low smoke.

Detailed Description
The utility model is described in further detail below with reference to the embodiments of the drawings.
Embodiment 1 as shown in fig. 1 and 2, the burner in this embodiment includes a burner body 5 and a heat collecting cover, and the burner body 5 is provided in the heat collecting cover.
Referring to fig. 3, the heat collecting cover in this embodiment includes a cover body 1 and four cushion blocks 4 disposed at the lower end of the cover body 1, where the bottom of the cushion blocks 4 is in contact with a panel 6. The cover body 1 is in an inverted cone frustum shape, the middle part forms a region for arranging the furnace end or the burner, the cover body 1 is provided with a secondary air supply hole 11, a baffle plate 3 is arranged in the secondary air supply hole 11, and the baffle plate 3 protrudes from the inner side surface of the cover body 1 and has a gap for entering secondary air with the inner edge of the secondary air supply hole 11. The baffle 3 is provided with a vent 31.
Four pot supporting feet 2 are uniformly arranged at the upper end of the cover body 1 in the circumferential direction, and secondary air supply holes 11 are formed in the position, right below the pot supporting feet 2, of the cover body 1. The burner body 5 is provided with an outer ring fire cover 51, and outer fire holes 52 are uniformly arranged on the outer ring of the outer ring fire cover 51.
The secondary air supply holes 11 are arranged in two rows from top to bottom, and the two rows of secondary air supply holes 11 are staggered up and down.
