The horizontal cover 111 and the vertical cover 112 may be integrally formed or assembled together through an assembling process.
A plurality of ventilation holes 1121 are formed at intervals in the circumferential direction of the vertical cover body 112, and air outside the vertical cover body 112 is supplied into the interior of the energy collecting cover 100 for a kitchen through the ventilation holes 1121. Specifically, the vent holes 1121 are arranged circumferentially along the cowl body 112 so that the secondary air is uniformly supplemented to the combustor 200 from all directions. The shape of the ventilation hole 1121 is not limited, and may be circular, square, or irregular, and the ventilation hole 1121 on the same vertical cover body 112 may have different shapes. Fig. 1 illustrates a shape and an arrangement of the vent holes 1121, which employ a quadrilateral hole and a triangular hole, wherein the quadrilateral star and the triangular hole are staggered with each other, but the invention is not limited to the scope of the invention.
The energy collecting hood 100 for the kitchen range further includes an inner hood 120, and the upper end of the inner hood 120 is fixed to the inner wall of the vertical hood body 112, and the two may be integrally formed or fixed to each other through an assembling process. The upper end of the inner cover 120 is located above the ventilation hole 1121, and accordingly, the secondary air is supplied from the lower surface of the inner cover 120.

In this embodiment, the upper guide portion 122 is ring-shaped and gradually extends downward from the outer circumference thereof to the inner circumference thereof, thereby increasing the resistance of the secondary air and improving the preheating effect.
In this embodiment, the vertical guide 123 gradually extends toward the center of the kitchen range hood 100 from the upper end to the lower end thereof, thereby facilitating the downward guide of the secondary air.
In this embodiment, the lower guide portion 121 is lower than the ventilation hole 1121, so that the length of the movement path of the secondary air is increased, thereby improving the preheating effect and further improving the heat efficiency.
In this embodiment, the energy collecting hood 100 for a kitchen range further includes a guide plate 130, a lower end of the guide plate 130 is fixedly connected to the vertical hood body 112 and is located below the ventilation hole 1121, a gap is maintained between an upper end of the guide plate 130 and the upper guide portion 122, and a gap is maintained between the guide plate 130 and the inner wall of the vertical hood body 112 and the vertical guide portion 123. In use, the secondary air enters between the air deflector 130 and the upper guide portion 122 through the air vent 1121, flows into the gap between the vertical guide portion 123 and the air deflector 130 through the gap between the upper end of the air deflector 130 and the upper guide portion 122, and further flows toward the lower surface of the lower guide portion 121. The embodiment increases the resistance to the secondary air by arranging the guide plate 130, increases the length of the secondary air movement path, and improves the secondary air preheating effect, thereby improving the heat efficiency.
In this embodiment, the baffle 130 includes an upper baffle portion 131 and a lower baffle portion 132, and the lower baffle portion 132 gradually extends upward from the outer ring to the inner ring thereof, so as to increase the resistance to the secondary air; the upper guide part 131 is bent upward with respect to the lower guide part 132, so that the secondary air flows to the vertical guide part 123 at a high speed along the lower surface of the upper guide part 122, thereby improving the preheating effect of the secondary air.
In this embodiment, the outer cover 110 further includes pan support legs 113, the horizontal cover body 111 has a plurality of mounting holes 1111 arranged at intervals, the pan support legs 113 correspondingly pass through the mounting holes 1111, and the pan support legs 113 are positioned on the horizontal cover body 111. Specifically, the pot support 113 is used to support a pot, and the pot support 113 may be plate-shaped. The part of the pan support leg 113 protruding out of the transverse cover 111 and the transverse cover 111 form a mutual limit in the up-down direction, and the lower end of the pan support leg 113 can be fixed on the inner cover 120 through a fastener.
Example 2
Please refer to fig. 4-5 for understanding the present embodiment. The embodiment provides a gas stove, which comprises the stove energy collecting cover 100 according to the embodiment 1.
The gas stove 1000 further comprises a liquid containing disc 300, the vertical cover body 112 is positioned on the liquid containing disc 300, the liquid containing disc 300 is annular, the outer ring of the liquid containing disc 300 is bent downwards and then bent towards the horizontal direction, so that an open annular positioning groove is formed, the lower end of the vertical cover body 112 is positioned on the positioning groove, and the stability of the energy collecting cover 100 for the stove is guaranteed.
An annular preheating channel 400 is formed between the lower guide part 121 and the liquid containing disc 300, the height of the preheating channel 400 is gradually reduced from the outer ring to the inner ring of the preheating channel, and the height of the preheating channel 400 is not less than 6 mm. Wherein, the part opposite to the lower guiding part 121 on the liquid containing disc 300 is a plane, and along with the gradual reduction of the height of the lower guiding part 121 from the outer ring to the inner ring thereof, the height of the preheating channel 400 is reduced, so that the flow velocity of the secondary air is improved, which is beneficial to obtaining better preheating effect.
