Some embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Example one

As shown in fig. 1 to 3, the present embodiment provides a kitchen range, which includes a burner 40, a burner 10, and a water pan 80, wherein the burner 40 has a lower connecting outer ring 43, the water pan 80 is sleeved on an outer peripheral surface of the lower connecting outer ring 43, the burner 10 has an upper connecting outer ring 13, the upper connecting outer ring 13 is connected to the lower connecting outer ring 43 through an outer heat insulation member 20, and the outer heat insulation member 20 is disposed between an inner peripheral surface of the lower connecting outer ring 43 and an outer peripheral surface of the upper connecting outer ring 13.

By providing the water receiving tray 80 on the outer circumferential surface of the lower connection outer ring 43, a path along which the burner 40 radiates heat to the burner 10 through a space outside the lower connection outer ring 43 can be blocked. Furthermore, by providing the heat insulating member between the inner peripheral surfaces of the lower connecting outer rings 43 and the outer peripheral surfaces of the upper connecting outer rings 13, not only the heat conduction of the lower connecting outer rings 43 directly to the upper connecting outer rings 13 is interrupted, but also the solid portions of the lower connecting outer rings 43 are located outside the upper connecting outer rings 13, and if heat radiation is generated, radiation is also emitted toward the water receiving tray 80, rather than the portion of the burner 10 located inside the upper connecting outer rings 13. Thereby, the speed at which the burner 10 is subjected to heat transfer by the burner 40 is significantly reduced, and the temperature of the burner 10 is reduced. After the temperature of the burner 10 is reduced, the speed of transferring heat on the burner 10 to the electric elements and the rubber sealing parts of the stove is also reduced, which is beneficial to avoiding the problems that the temperature rise inside the stove is large, the service life of the electric elements and the rubber sealing parts is influenced, and the temperature rise of the gas valve is large.

In an alternative embodiment, the outer insulation 20 is annular in shape.

Set up outer heat insulating part 20 into the ring shape, not only make the inner peripheral surface of lower connection outer loop 43 all can be supported by upper connection outer loop 13 through outer heat insulating part 20 in 360 within ranges, the installation stability of outer heat insulating part 20 has been improved, and compare in the heat insulating part through a plurality of even points and support and thermal-insulated mode, can utilize the low characteristic of outer heat insulating part 20 heat transfer rate, with the heat transfer mode of original heat radiation + air conduction, become to utilize heat insulating part to conduct, thereby obviously reduce heat transfer rate, be favorable to reducing the inside temperature rise of cooking utensils.

In an alternative embodiment, the outer heat insulator 20 has an inverted L-shaped cross-section, a horizontal portion of the inverted L-shape presses an upper end surface of the upper joint outer ring 13 and is pressed by an inner end surface of the stepped hole of the lower joint outer ring 43, and a vertical portion of the inverted L-shape is disposed between an outer circumferential surface of the upper joint outer ring 13 and an inner circumferential surface of the lower joint outer ring 43.

The cross section of the outer heat insulation member 20 is set to be inverted L-shaped, so that not only is the heat transfer speed between the inner circumferential surface of the lower connecting outer ring 43 and the outer circumferential surface of the upper connecting outer ring 13 reduced by the vertical part of the L-shape, but also the inner end surface of the stepped hole of the upper connecting outer ring 13 can be pressed against the upper end surface of the lower connecting outer ring 43 by the horizontal part of the L-shape, so that the burner 40 is firmly installed, and simultaneously, the heat absorption speed of the lower connecting outer ring 43 can be remarkably reduced by the blocking effect of the horizontal part of the L-shape, and the over-high temperature of the burner 10 caused by the over-high heat absorption speed of the upper end surface of the lower connecting outer ring 43 is avoided.

In an alternative embodiment, the lower end of the vertical portion of the inverted L-shape of the cross-section of the outer insulation member 20 is not higher than the lower end surface of the upper connecting outer ring 13.

By setting the vertical portion of the inverted L-shape not higher than the lower surface of the upper connection outer ring 13, the inner circumferential surface of the lower end portion of the upper connection outer ring 13 can be prevented from directly radiating toward the outer circumferential surface of the lower connection outer ring 43, the heating rate of the lower connection outer ring 43 can be reduced, and the temperature rise of the burner 10 can be reduced.

Specifically, in the present embodiment, the lower end surface of the vertical portion of the inverted L shape is flush with the lower end surface of the upper connection outer ring 13. With this arrangement, the lower end of the outer heat insulator 20 is prevented from contacting a portion of the burner 10 located near the lower connection outer ring 43, the upper connection outer ring 13 is lifted up due to a size problem, and the burner 40 cannot be stably mounted, and the lower end of the outer heat insulator 20 is prevented from contacting a portion of the burner 10 located near the lower connection outer ring 43 and transferring heat thereto. In the flush condition, except for the inevitable event that the inner circumferential surface of the upper outer joint ring 13 is slowly transferred heat to the outer circumferential surface of the lower outer joint ring 43 through the outer heat insulator 20, the lower end surface of the upper outer joint ring 13 is merely transferred heat by radiation to the portion of the burner head 10 located beside the lower outer joint ring 43, i.e., the portion below the lower end of the outer heat insulator 20. If contact is made, conduction can occur directly, and when the annular space below the outer insulation 20 is low, the rate of such radiation is significantly lower than the rate of conduction, thereby reducing the rate of heat transfer.

In an alternative embodiment, the burner 40 comprises a lower connecting inner ring 41, the burner 10 comprises an upper connecting inner ring 11, the upper connecting inner ring 11 is connected with the lower connecting inner ring 41 by an inner heat insulator 30, and the inner heat insulator 30 is arranged between the inner circumferential surface of the lower connecting inner ring 41 and the outer circumferential surface of the upper connecting inner ring 11.

By arranging the inner heat insulation member 30 between the lower connecting inner ring 41 of the burner 40 and the upper connecting inner ring 11 of the burner 10, the heat transfer speed of the lower connecting inner ring 41 and the upper connecting inner ring 11 can be remarkably reduced, so that the temperature rise of the burner 10 is controlled, and the temperature rise inside the stove is further controlled.

In an alternative embodiment, the inner insulation 30 is annular in shape.

The inner heat insulation piece 30 is arranged to be annular, so that the inner circumferential surface of the lower connecting inner ring 41 can be supported by the upper connecting inner ring 11 through the inner heat insulation piece 30 within the range of 360 degrees, the mounting stability of the inner heat insulation piece 30 is improved, and compared with a mode of supporting and insulating heat through the heat insulation pieces of a plurality of uniform point positions, the heat transmission speed of the inner heat insulation piece 30 is low, the original heat radiation and air conduction heat transmission mode is changed into the heat transmission mode through the heat insulation piece, the heat transmission speed of the upper connecting inner ring 11 is obviously reduced, and the reduction of the temperature rise inside the cooker is facilitated.

In an alternative embodiment, the cross-section of the inner heat insulating member 30 is an inverted L-shape, a horizontal portion of the inverted L-shape is located between an inner end surface of the stepped hole of the lower connecting inner ring 41 and an upper end surface of the upper connecting inner ring 11, a vertical portion of the inverted L-shape is disposed between an outer circumferential surface of the upper connecting inner ring 11 and an inner circumferential surface of the lower connecting inner ring 41, and a gap is left between the inner end surface of the stepped hole of the lower connecting inner ring 41 and a top surface of the inner heat insulating member 30.

The cross section of the inner heat insulating member 30 is formed in an inverted L shape, so that the heat transfer rate between the inner circumferential surface of the lower connecting inner ring 41 and the outer circumferential surface of the upper connecting inner ring 11 is reduced by using the vertical portion of the L shape, and a gap is formed above or below the horizontal portion of the inner heat insulating member 30, so that the burner 40 is prevented from being positioned too much when being mounted on the burner 10, and the mounting is not firm and stable. In addition, the blocking effect of the horizontal portion of the L-shape can also significantly reduce the heat absorption speed of the lower connecting inner ring 41, so as to avoid the over-high temperature of the burner 10 caused by the over-fast heat absorption of the upper end surface of the lower connecting inner ring 41.

In an alternative embodiment, the lower end of the inverted L-shaped vertical portion of the cross section of the inner heat insulating member 30 is not higher than the lower end surface of the upper connecting inner ring 11.

By setting the vertical portion of the inverted L-shape not higher than the lower surface of the upper connecting inner ring 11, the inner circumferential surface of the lower end portion of the upper connecting inner ring 11 can be prevented from directly radiating downward from the outer circumferential surface of the lower connecting inner ring 41, the heating rate of the lower connecting inner ring 41 can be reduced, and the temperature rise of the burner 10 can be reduced.

Specifically, in the present embodiment, the lower end surface of the vertical portion of the inverted L shape is lower than the lower end surface of the upper connecting inner ring 11. With this arrangement, the radiation of the inner end of the stepped hole of the lower inner joint ring 41 to the outer circumferential surface of the upper inner joint ring 11 can be reduced, and the radiation of the portion of the burner 40 located outside the lower inner joint ring 41 to the outer circumferential surface of the upper inner joint ring 11 can also be reduced. Although the heat insulator cannot cover the entire outer circumferential surface of the upper connecting inner ring 11, since the uppermost portion is closer to the burner 40 and is more radiated, the total amount of heat radiation received by the outer circumferential surface of the upper connecting inner ring 11 can be significantly reduced by covering the outer circumferential surface of the tip end of the upper connecting inner ring 11 with the inner heat insulator 30.

Specifically, the burner feet 15 are connected to the base plate 60 by screws. As shown in fig. 5, the lower heat insulation member 50 may be a circular ring body with a rectangular cross section, and the outer circumferential surface is a cylindrical surface, the inner circumferential surface is a cylindrical surface, and the screw passes through the middle of the circular ring body.

Through being equipped with down heat insulating part 50 between furnace end footing 15 and chassis 60, can obviously weaken furnace end 10 and be in the heat conduction effect of chassis 60 at the footing to reduced the heat that furnace end 10 that the chassis 60 received transmitted, made the temperature rise of chassis 60 reduced, reduced the inside temperature rise of cooking utensils.

in the first embodiment, a gap is left between the inner end surface of the stepped hole of the lower connecting inner ring 41 and the top surface of the inner heat insulating member 30. In fact, a gap may be left between the inverted L-shaped horizontal portion of the inner heat insulator 30 and the upper end surface of the upper connecting inner ring 11, or gaps may be left on the upper surface and the lower surface of the inverted L-shaped horizontal portion of the inner heat insulator 30, respectively, and an over-positioning prevention function may also be performed.

In the first embodiment, the lower end surface of the outer heat insulator 20 is flush with the lower connection outer ring 43, and actually, the lower end surface of the outer heat insulator 20 may be lower than the lower connection outer ring 43 as long as it does not directly contact with the portion of the burner 10 other than the upper connection outer ring 13.

In the second embodiment, the lower heat insulating member 50 is a circular ring, and the inner and outer peripheral surfaces thereof are cylindrical surfaces, and in fact, the outer peripheral surface of the lower heat insulating member 50 may be set to be a quadrangular prism surface according to the convenience of manufacturing materials, as long as the inner peripheral surface of the lower heat insulating member 50 is a cylindrical surface and is attached to the threaded portion of the screw 70 as much as possible, thereby reducing the direct transfer of heat.
