[0059] The present invention is further described below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.
[0060] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.
[0061] like Figure 1-7 As shown, this embodiment provides a stove 100. The stove 100 is a gas stove that uses liquefied gas or natural gas to generate an open flame and is used for cooking. The stove 100 includes: a pot support 110, a liquid tray 130 and a burner 140. The pot support 110 and the liquid tray 130 are both sleeved on the outer peripheral side of the burner 140, and the pot support 110 is placed on the liquid tray 130.
[0062] The pot support 110 includes a hollow energy-gathering ring 111 . A lower air inlet channel 103 is formed between the upper surface of the liquid receiving pan 130 and the lower surface of the energy-gathering ring 111 , and the lower air inlet channel 103 extends upward and toward the center of the energy-gathering ring 111 .
[0063] The stove 100 forms an inclined lower air inlet channel 103 between the upper surface of the liquid receiving tray 130 and the lower surface of the energy focusing ring 111, which guides the secondary air to the inside of the energy focusing ring 111 and provides it to the fire cover of the burner 140, thereby improving the combustion efficiency of the burner 140.
[0064] The energy gathering ring 111 has an inner peripheral wall protruding toward the inner peripheral side of the energy gathering ring 111 , and a lower air inlet channel 103 is formed between a lower surface 116 of the inner peripheral wall and an upper surface of the liquid receiving tray 130 .
[0065] The inner circumferential wall of the energy gathering ring 111 protrudes toward the inner circumference, so that a lower air inlet passage 103 is formed by utilizing the lower surface 116 of the inner circumferential wall and the upper surface of the liquid receiving tray 130 .
[0066] The lower surface 116 of the inner peripheral wall extends upward and toward the center of the energy focusing ring 111 ; the upper surface 115 of the inner peripheral wall extends downward and toward the center of the energy focusing ring 111 .
[0067] The upper surface 115 of the inner peripheral wall is inclined to form a reflective surface. When the high-temperature flue gas generated by the burner 140 is discharged from the upper part, the upper surface 115 of the inner peripheral wall reflects the heat to the bottom of the pot, thereby increasing the temperature of the bottom of the pot.
[0068] The outer peripheral wall 113 of the energy focusing ring 111 is formed in a straight plate shape, so that the cross section of the energy focusing ring 111 is formed in a substantially triangular shape.
[0069] The stove 100 further includes a burner 140 , and an extension line of a fire hole of an outer ring fire cover 142 of the burner 140 forms an angle of 10° with the upper surface 115 of the inner peripheral wall.
[0070] The angle of 10° between the extension line of the fire outlet hole of the outer ring fire cover 142 and the upper surface 115 of the inner peripheral wall maximizes the heat reflected from the upper surface of the inner peripheral wall to the bottom of the pot.
[0071] The upper surface 115 of the inner peripheral wall and the lower surface 116 of the inner peripheral wall are connected via an arc-shaped connecting portion 117 .
[0072] The upper surface 115 and the lower surface of the inner peripheral wall are connected by an arc-shaped connecting portion 117, which can avoid the formation of sharp parts that cause inconvenience in cleaning.
[0073] Alternatively, the upper surface 115 of the inner circumferential wall and the lower surface 116 of the inner circumferential wall may also be directly connected.
[0074] The pot support 110 further includes a C-shaped angle piece 121 , and the C-shaped angle piece 121 covers the energy focusing ring 111 from the outer peripheral side of the energy focusing ring 111 .
[0075] A C-shaped corner piece 121 is provided, and the C-shaped corner piece 121 covers the energy gathering ring 111 from the outer peripheral side of the energy gathering ring 111 , so as to avoid the corner piece from affecting the energy gathering effect of the energy gathering ring 111 .
[0076] The C-shaped angle piece 121 includes an upper support portion 123, an intermediate connection portion 124 and a lower support leg 125. The intermediate connection portion 124 is connected to one end of the upper support portion 123 close to the outer periphery and one end of the lower support leg 125 close to the outer periphery. The upper support portion 123 is used to support the pot, and the lower support leg 125 is used to be placed on the liquid tray 130.
[0077] The liquid receiving tray 130 includes a base 131 and a boss 132 arranged on the base 131. The side of the boss 132 is an inclined surface 133, and the inclined surface 133 extends toward the center and upward of the energy focusing ring 111. A lower air inlet channel 103 is formed between the inclined surface 133 and the lower surface of the energy focusing ring 111.
[0078] The boss 132 forms an inclined surface 133 , thereby forming the lower air inlet passage 103 .
[0079] The radial extension length of the inclined surface 133 of the boss 132 is smaller than the radial extension length of the lower surface 116 of the inner peripheral wall.
[0080] A plurality of slots 134 are provided on the inclined surface 133 of the boss 132 along the circumference of the liquid collecting pan 130 , and the slots 134 are engaged with the corner piece of the pot support 110 , specifically, with the lower legs 125 of the corner piece, so that the pot support 110 is stably supported on the liquid collecting pan 130 .
[0081] By providing a clamping groove 134 on the edge of the boss 132 , the pot support 110 can be conveniently installed on the liquid receiving tray 130 .
[0082] A lower air inlet 144 is provided at the lower portion of the side wall of the burner 140 , and the lower air inlet channel 103 faces the lower air inlet 144 .
[0083] The burner 140 has a lower air inlet 144, so that the secondary air entering from the lower air inlet channel 103 can be conveniently supplied to the fire cover inside the burner 140 to supplement the secondary air to the fire cover inside the burner 140. The lower air inlet channel 103 faces the lower air inlet 144, so that the secondary air entering from the lower air inlet channel 103 can directly enter the lower air inlet 144 ( Figure 7 The dotted line in the figure indicates the incoming secondary air), which provides secondary air to the inner ring fire cover 141 inside the burner 140, or the middle ring fire cover that may exist.
[0084] An angle of 5° is formed between the upper surface of the liquid receiving tray 130 and the lower surface of the energy focusing ring 111 .
[0085] The upper surface of the liquid receiving tray 130 and the lower surface of the energy focusing ring 111 form an angle of 5°, which can optimize the flow guidance effect and enhance the combustion efficiency.
[0086] The pot support 110 forms a roughly triangular energy-gathering ring 111, and the hollow energy-gathering ring 111 can be used for heat preservation and insulation to reduce heat loss. The overall annular cavity inside the energy-gathering ring 111 can gather high-temperature smoke for heat collection and improve combustion thermal efficiency.
[0087] The outer peripheral wall 113 of the energy gathering ring 111 is a vertical structure, and the inner peripheral wall has an inclined upper surface and a lower surface, and the interior is hollow. The angle between the inclination of the fire hole of the outer ring fire cover 142 of the burner 140 and the horizontal glass surface (the table 101 of the stove 100) is Φ1, and the angle between the lower surface of the outer peripheral wall 113 of the energy gathering ring 111 and the horizontal glass surface is Φ2, Φ1 = Φ2 ± 10°. The angle between the upper surface (inclined surface 133) of the liquid receiving pan 130 and the horizontal glass surface is Φ3, and the angle between the upper surface of the outer peripheral wall 113 of the energy gathering ring 111 and the horizontal glass surface is Φ4, Φ3 = Φ4 ± 10°.
[0088] When the stove 100 is burning, the outer wall 113 of the energy-gathering ring 111 is used to block the wind. At the same time, the vertical structure of the outer wall 113 can separate the secondary air from the high-temperature flue gas generated by the combustion, thereby reducing the radiation and convection heat loss, and playing the role of gathering heat energy and heat insulation. The lower surface 116 of the inner wall of the energy-gathering ring 111 and the upper surface of the liquid tray 130 form a lower air inlet channel 103, which together guides the secondary air to the inner side of the energy-gathering ring 111, thereby improving the combustion efficiency of the burner 140. At the same time, the high-temperature flue gas is discharged from the upper part, and the upper surface 115 of the inner wall of the energy-gathering ring 111 reflects the heat to the bottom of the pot, thereby increasing the temperature of the bottom of the pot.
[0089] At the same time, the hollow energy-gathering ring 111 and the slope design of the inner wall of the energy-gathering ring 111 can gather the high-temperature smoke from combustion in the annular cavity, thereby enhancing the heat energy exchange between the high-temperature smoke and the cookware, thereby improving the combustion efficiency.
