Detailed Description

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.

As shown in fig. 1 to 5, the reflection cover of the present embodiment includes: cover body 10, cover body 10 has diapire and lateral wall, the diapire of cover body 10 includes main reflecting region 1 and vice reflecting region 2, the both ends and the main reflecting region 1 of vice reflecting region 2 are connected, all be provided with louvre 12 on main reflecting region 1 and the vice reflecting region 2, the upper surface that is located the diapire of cover body 10 of main reflecting region 1 is main reflecting region plane of reflection, the upper surface that is located the diapire of the cover body 10 of vice reflecting region 2 is vice reflecting region plane of reflection, vice reflecting region plane of reflection is first reflection cambered surface, the height that highly is higher than its junction of being connected with main reflecting region plane of reflection at the middle part of vice reflecting region plane of reflection.

Use the technical scheme of this embodiment, the heating pipe sets up in cover body 10 and relative with main reflecting region 1, and vice reflecting region 2 corresponds the cold junction of heating pipe, and at cooking utensil during operation, most heat that the heating pipe sent can be sent by louvre 12 on the main reflecting region 1 with the food in the culinary art intracavity of heating main reflecting region 1 below. The other part heat of heating pipe can hit on first reflection cambered surface, then on the middle part slant reflection of first reflection cambered surface to the reflecting plate, hit heat on the reflecting plate again towards the middle part slant reflection of first reflection cambered surface to first reflection cambered surface, so carry out multiple reflection so that the heat that the heating pipe sent can be more hit the middle part of vice reflecting area 2. In the above-mentioned continuous reflection process, when the heat is reflected to the heat dissipation holes 12 on the secondary reflection region 2, the heat can be emitted from the heat dissipation holes 12 on the secondary reflection region 2 to heat the food in the cooking cavity below the secondary reflection region 2. Above-mentioned structure makes the culinary art chamber of 1 below in main reflecting area and the culinary art chamber of 2 below in the vice reflecting area all have sufficient heat to get into to make the temperature field in the culinary art intracavity even, improve the culinary art effect of food. In addition, in this embodiment, because the height of the middle part of the first reflection cambered surface is higher than the height of the connection part of the first reflection cambered surface and the main reflection area, in the process of continuous heat reflection, the closer to the middle part of the first reflection cambered surface, the more the heat reflection times are, the easier the heat reflection times are to be emitted from the heat emission hole 12, thereby ensuring that the cooking cavity below the secondary reflection area 2 has enough heat to enter.

As shown in fig. 3, in the present embodiment, the portion of the bottom wall of the cover body 10 located between the right side of the imaginary line L1 and the left side of the imaginary line L2 is the sub reflection area 2, and the other portion is the main reflection area 1. As shown in fig. 5 and 8, a broken line L3 indicates the position of the reflecting plate.

Specifically, referring to fig. 5, the arrow in fig. 5 represents a heat reflection path, and since the middle of the first reflection arc surface is high and the two ends are low, the closer to the middle of the first reflection arc surface, the smaller the heat reflection angle (relative to the normal line), which increases the heat reflection times, and more heat can be reflected to the middle of the secondary reflection area 2, so as to increase the probability that heat is emitted from the heat dissipation hole 12 in the middle of the secondary reflection area 2, thereby ensuring that the cooking cavity below the secondary reflection area 2 has enough heat to enter.

From the above analysis, it is known that when heat hits the lower end of one inclined surface, the heat is more easily reflected to the upper end of the inclined surface, and the concentration of heat received by the upper end of the inclined surface can be effectively increased.

The low point at the connection between the main reflection region 1 and the sub-reflection region 2 is not necessarily the lowest point of the reflection cover, and the lowest point may be located in the main reflection region 1.

Of course, in other embodiments not shown in the drawings, the reflecting surface of the secondary reflecting region may also be a reflecting inclined surface (plane), and the above structure also has the effect of increasing the probability of heat being emitted from the heat dissipating holes 12 in the middle of the secondary reflecting region 2.

In this embodiment, the first reflective curved surface may be formed in two ways, the first way: the first arc surface is constituted by a plurality of first arcs 13 arranged in the radial direction of the reflector, the first arcs 13 extending in the circumferential direction of the reflector. The second mode is as follows: the first reflective arc face is constituted by a plurality of second arcs 14 arranged in the circumferential direction of the reflector, the second arcs 14 extending in the radial direction of the reflector. It should be noted that the first reflective arc surfaces constructed in the above two ways are the same first reflective arc surface.

In this embodiment, the center of the first arc 13 is located below the reflector, and the radius of the first arc 13 is between 65mm and 75 mm. If the radius of the first arc line 13 is too large (i.e. the upward camber of the first arc line 13 is large in fig. 5), on the one hand, the probability of the emission of the heat dissipation holes 12 in the middle of the secondary reflection area 2 is reduced to some extent; on the other hand, the reflector is difficult to process, and the defective rate is high; if the radius of the first arc 13 is too small, the probability of emission from the heat emission hole 12 in the middle of the secondary reflecting region 2 is also reduced to some extent. Preferably, the radius of the first arc 13 is between 68mm and 72 mm. Further preferably, in the present embodiment, the radius of the first arc 13 is 70 mm.

As shown in fig. 3 and 9, also, in order to increase the temperature of the cooking cavity corresponding to the outer edge of the secondary reflection area 2, in the present embodiment, the plurality of second arcs 14 are gradually increased in the direction n from the center of the reflection housing to the outer edge of the secondary reflection area 2. Since heat is more easily reflected to the upper end of an inclined surface when the heat hits the lower end of an inclined surface, the concentration of heat received by the upper end of the inclined surface can be effectively increased. Therefore, the above structure enables the concentration of heat received by the higher end of the second arc line 14 (i.e. the end close to the outer edge of the secondary reflection area 2) to be effectively increased, so that heat is more easily emitted from the heat emission holes 12 at the outer edge of the secondary reflection area 2, and finally the purpose of increasing the temperature of the cooking cavity corresponding to the outer edge of the secondary reflection area 2 is achieved. Of course, in other embodiments not shown in the drawings, the first reflection arc surface may also be constituted by a plurality of oblique lines arranged in the circumferential direction of the reflection cover. The above structure can also achieve the purpose of increasing the temperature of the cooking cavity corresponding to the outer edge of the secondary reflection area 2.

It should be noted that the second reflective arc surfaces constructed in the above two ways are the same second reflective arc surface.

As shown in fig. 6 to 8, in the present embodiment, the third arc line 15 gradually rises from inside to outside in the radial direction of the reflector. Similarly, the above structure enables the density of the heat received by the higher end of the third arc line 15 (i.e. the end close to the outer edge of the main reflection area 1) to be effectively increased, so that the heat is more easily emitted from the heat emission hole 12 at the outer edge of the main reflection area 1, and finally the purpose of increasing the temperature of the cooking cavity corresponding to the outer edge of the main reflection area 1 is achieved.

As shown in fig. 2, 9 and 10, in the present embodiment, the point on the fourth arc 16 gradually rises in the direction n from the center of the reflection housing to the outer edge of the secondary reflection area 2. In a similar way, the heat intensity received by the higher end of the fourth arc line 16 can be effectively improved by the structure, so that the heat is easier to reflect to one side, close to the auxiliary reflecting area 2, of the main reflecting area 1, further more heat can enter the auxiliary reflecting area 2, the temperature field in the cooking cavity is ensured to be uniform, and the cooking effect of food is improved.

As shown in fig. 1 and 2, in the present embodiment, the reflection housing further includes: and the limiting structure 20 is arranged on the cover body 10. The structure is convenient for the positioning and installation of the reflector, thereby improving the use experience of users.
