[0001] The present application relates to the technical field of household appliances, in particular to a cooking appliance. BACKGROUND

[0002] At present, cooking appliances such as electric rice cookers and electric pressure cookers are widely used in people's daily life. The cooking appliance includes a pot body and an inner pot. The inner pot is located in the pot body and has a cooking cavity for containing food. The bottom of the inner pot in the pot body is provided with a bottom heating element, and the outer side of the inner pot in the pot body is provided with an infrared heating element. When the food in the cooking cavity is heated, the bottom heating element heats the food in the cooking cavity by self-heating, and the infrared heating element heats the food in the cooking cavity by emitting infrared rays into the cooking cavity. In the prior art, as shown in the disclosure of patent 201822067598.2, the distance between the bottom heating element and the infrared heating element is relatively close, and the main heating range of the bottom heating element and the infrared heating element is concentrated in the lower part of the cooking cavity. The food in the lower part of the cooking cavity can be well heated. However, the inner pot is a transparent structure with poor heat conduction efficiency. When the cooking cavity contains a large amount of food, the heat in the lower part of the cooking cavity cannot be transferred to the upper part of the cooking cavity in a short time, and the food in the upper part of the cooking cavity will be poorly heated, which ultimately leads to inconsistent heating of the food in the upper and lower parts of the cooking cavity, seriously affecting the cooking effect of the food. Therefore, how to ensure the consistent heating of the food in the upper and lower parts of the cooking cavity has become a technical problem to be solved. CONTENT OF THE UTILITY MODEL

[0003] The purpose of the present application is to provide a cooking appliance which can ensure the consistent heating of the food in the upper and lower parts of the cooking cavity.

[0004] The embodiments of the present application are implemented as follows:

[0005] The present application provides a cooking appliance, which includes a pot body and a cover body. The pot body is provided with an inner pot having a cooking cavity. A reflective cover and an infrared heating element are arranged between the inner side wall of the pot body and the outer side wall of the inner pot. The infrared heating element is used to radiate infrared rays into the cooking cavity. The reflective cover and the outer side wall of the inner pot form a heating cavity therebetween. The infrared heating element is arranged in the heating cavity. The top of the heating cavity is provided with a first opening, and the first opening is inclinedly arranged towards the outer side wall of the inner pot.

[0006] In an embodiment, the top end of the reflective cover extends towards the inner pot to form a turned-up edge, and the projection of the turned-up edge on a horizontal plane is located within the projection range of the infrared heating element on the horizontal plane.

[0007] In an embodiment, the infrared heating element is arranged in a circular tube shape, and the extension line of the connecting line between the end face of the turned-up edge and the maximum capacity scale line on the side wall of the inner pot is tangent to the outer surface of the infrared heating element.

[0008] In an embodiment, the intersection of the extension line of the side wall of the first opening and the side wall of the inner pot is not lower than the maximum capacity scale line on the side wall of the inner pot and is below the pot rim of the inner pot.

[0009] In an embodiment, the axial section of the side wall of the reflecting cover is a parabola, the center of the infrared heating element is located at the focus of the parabola, and the symmetry axis of the parabola is upwardly inclined towards the inner pot.

[0010] In an embodiment, the axial section of the side wall of the inner pot is outwardly inclined and the included angle between the axial section and the horizontal plane is a, the included angle between the symmetry axis of the parabola and the horizontal plane is b, and the difference between a and b is 80°-100°.

[0011] In an embodiment, the distance between the maximum capacity scale line on the side wall of the inner pot and the bottom of the inner pot is H, and the distance between the infrared heating element and the bottom of the inner pot is 0.3H-0.5H.

[0012] In an embodiment, a heat insulation member is arranged between the inner side wall of the pot body and the outer side wall of the inner pot, the heat insulation member is arranged outside the reflecting cover, and a third opening corresponding to the first opening is formed between the top end of the heat insulation member and the side wall of the inner pot.

[0013] In an embodiment, a gap is arranged between the heat insulation member and the reflecting cover to form an air insulation layer.

[0014] In an embodiment, the inner side wall of the reflecting cover is coated with a reflective coating.

[0015] Compared with the prior art, the application has the following beneficial effects:

[0016] In the application, the reflecting cover and the outer side wall of the inner pot enclose a heating cavity, the infrared heating element is arranged in the heating cavity, and a first opening is arranged at the top of the heating cavity. By arranging the first opening, the reflecting cover does not completely cover the infrared heating element in the vertical direction, so that part of the infrared radiation of the infrared heating element can penetrate the inner pot after being emitted through the first opening and enter the cooking cavity above to heat the food in the upper part of the cooking cavity. At the same time, in the application, the first opening is inclined towards the outer side wall of the inner pot, which makes the upper side wall of the reflecting cover close to the first opening inclined towards the outer side wall of the inner pot, so that part of the infrared radiation of the infrared heating element on the upper side wall of the reflecting cover can be reflected by the reflecting cover to the first opening in the inclined upward direction and penetrate the inner pot through the first opening to enter the cooking cavity above to heat the food in the upper part of the cooking cavity.

[0017] As can be seen, in the application, the infrared heating element has a large radiation range and can heat the food in the upper part of the cooking cavity, which improves the heating rate of the food in the upper part of the cooking cavity and solves the problem of poor heating of the food in the upper part of the cooking cavity, thereby fully ensuring the consistency of the heating of the food in the upper and lower parts of the cooking cavity.

[0037] The technical solutions of the present application will be described below in conjunction with the drawings.

[0038] Example one:

[0039] As Figure 1 And Figure 2As shown, the cooking utensil 1 comprises a pot body 10 and an inner pot 30 arranged in the pot body 10; wherein the pot body 10 has an opening at the top, and a receiving cavity is arranged in the pot body 10, and the user can put the inner pot 30 into the receiving cavity through the opening, or the user can take the inner pot 30 out of the receiving cavity through the opening. The cooking utensil 1 further comprises a cover 20 rotatably connected to the top of the pot body 10, and when the cover 20 is completely covered on the pot body 10, the inner pot 30 is enclosed in the pot body 10. The inner pot 30 has a cooking cavity for containing food materials such as rice products and soup products, and the cooking cavity has an opening at the top, through which the user can put the food materials into the cooking cavity, or the user can take out the cooked food materials.

[0040] As shown in Figure 1 and Figure 2 , the cooking utensil 1 further comprises a bottom heating element 70, which is arranged in the pot body 10 and at the bottom of the inner pot 30. Specifically, the bottom heating element 70 can be an electric heating disc, an infrared heating element or an electromagnetic coil type heating element. When the bottom heating element 70 is an electric heating disc or an electromagnetic coil type heating element, the bottom heating element 70 heats the food materials in the cooking cavity by self-heating; when the bottom heating element 70 is an infrared heating element, the infrared rays radiated by the bottom heating element 70 can penetrate the inner pot 30 into the cooking cavity to heat the food materials in the cooking cavity.

[0041] As shown in Figure 4 and Figure 5 , the cooking utensil 1 further comprises an infrared heating element 50 arranged around the outer sidewall of the inner pot 30, and the infrared rays radiated by the infrared heating element 50 can penetrate the inner pot 30 into the cooking cavity to heat the food materials in the cooking cavity. In order to enable the infrared rays to penetrate the inner pot 30 into the cooking cavity, the inner pot 30 needs to be made of a light-transmitting material; for example, the inner pot 30 can be made of glass.

[0042] In the prior art, when the food materials in the cooking cavity are heated, the distance between the bottom heating element 70 and the infrared heating element 50 is relatively short, and the main heating ranges of the bottom heating element 70 and the infrared heating element 50 are both concentrated in the lower part of the cooking cavity, and the food materials located in the lower part of the cooking cavity can be well heated; however, the inner pot 30 has a transparent structure and has poor heat conduction efficiency, and when the cooking cavity contains a large amount of food materials, the heat in the lower part of the cooking cavity cannot be transferred to the upper part of the cooking cavity in a short time, and the food materials located in the upper part of the cooking cavity will be poorly heated, which ultimately leads to inconsistent heating of the food materials in the upper and lower parts of the cooking cavity, and seriously affects the cooking effect of the food materials.

[0043] To solve the above problems, the embodiment provides a cooking utensil 1. In addition to the above-mentioned elements, the cooking utensil 1 in the embodiment further comprises a reflecting cover 40. The reflecting cover 40 is located between the inner side wall of the pot body 10 and the outer side wall of the inner pot 30. The reflecting cover 40 and the outer side wall of the inner pot 30 enclose a heating cavity 60. The reflecting cover 40 can be a whole ring structure, or the reflecting cover 40 can be a ring structure formed by splicing a plurality of arc-shaped elements, or the reflecting cover 40 can be a ring structure formed by splicing a plurality of whole ring structures along the axis direction of the cooking utensil 1. The reflecting cover 40 can be a strictly closed ring structure, or the reflecting cover 40 can be a local ring structure with an opening. When the reflecting cover 40 is arranged around the outer side wall of the inner pot 30, the reflecting cover 40 and the outer side wall of the inner pot 30 enclose the heating cavity 60.

[0044] The infrared heating element 50 is arranged in the heating cavity 60. The infrared heating element 50 can be graphite, carbon or coated metal. As shown in FIG. 1, the infrared heating element 50 can be a whole ring structure, or as shown in FIG. 2, the infrared heating element 50 can be a ring structure formed by splicing a plurality of arc-shaped heating elements. Figure 2 As shown in FIG. 1, the infrared heating element 50 can be a whole ring structure, or as shown in FIG. 2, the infrared heating element 50 can be a ring structure formed by splicing a plurality of arc-shaped heating elements. Figure 3

[0045] The top of the heating cavity 60 is provided with a first opening 61. That is, in the embodiment, the reflecting cover 40 does not completely cover the infrared heating element 50 in the vertical direction. The first opening 61 is inclined to the outer side wall of the inner pot 30. Of course, it can be understood that when the upper side wall of the reflecting cover 40 close to the first opening 61 is inclined to the outer side wall of the inner pot 30, the first opening 61 is inclined to the outer side wall of the inner pot 30.

[0046] In the embodiment, because the infrared heating element 50 is located in the heating cavity 60 enclosed by the reflecting cover 40 and the inner pot 30, part of the infrared radiation from the outer surface of the infrared heating element 50 will not be irradiated on the pot body 10, but will be reflected to the cooking cavity by the reflecting cover 40, reducing the loss of infrared radiation energy and improving the heating intensity of the food in the cooking cavity. At the same time, the infrared radiation from the infrared heating element 50 to the pot body 10 is reduced, the temperature rise of the pot body 10 is reduced, the circuit elements in the pot body 10 are protected, the service life of the cooking utensil 1 is prolonged, and the user is effectively prevented from being scalded.

[0047] Further, as shown in FIG. 3, the reflecting cover 40 can be a local ring structure with an opening. Figure 2 Figure 6 ​​As shown, part of the infrared rays radiated by the infrared heating element 50 can directly penetrate the inner pot 30 into the cooking cavity to heat the food materials in the lower part of the cooking cavity. Further, the first opening 61 on the heating cavity 60 allows part of the infrared rays radiated by the infrared heating element 50 to penetrate the inner pot 30 into the cooking cavity above the lower part of the cooking cavity to heat the food materials in the upper part of the cooking cavity. Furthermore, in this embodiment, part of the infrared rays radiated by the infrared heating element 50 onto the reflecting cover 40 can be reflected by the reflecting cover 40 to the lower part of the cooking cavity to heat the food materials in the lower part of the cooking cavity. Meanwhile, in this embodiment, the first opening 61 is obliquely arranged towards the outer sidewall of the inner pot 30, which allows the upper sidewall of the reflecting cover 40 close to the first opening 61 to be obliquely arranged towards the outer sidewall of the inner pot 30. Thus, part of the infrared rays radiated by the infrared heating element 50 onto the upper sidewall of the reflecting cover 40 can be reflected by the reflecting cover 40 in the obliquely upward direction to the first opening 61 and penetrate the inner pot 30 to the upper part of the cooking cavity to heat the food materials in the upper part of the cooking cavity.

[0048] As can be seen, in this embodiment, the infrared heating element 50 has a large radiation range and can heat the food materials in the upper and lower parts of the cooking cavity simultaneously, which improves the heating rate of the food materials in the upper part of the cooking cavity and solves the problem of poor heating of the food materials in the upper part of the cooking cavity, thereby fully ensuring the consistency of heating of the food materials in the upper and lower parts of the cooking cavity.

[0049] In addition, in this embodiment, part of the infrared rays radiated by the infrared heating element 50 onto the reflecting cover 40 can also be guided by the reflecting cover 40 in the obliquely upward direction to the cover 20 of the cooking appliance 1. Such a path of the infrared rays allows the infrared rays to heat the water vapor in the cooking cavity and the cover 20, which reduces the condensed water on the cover 20, alleviates the problem of water accumulation when the cover 20 is opened, and improves the user experience.

[0050] Of course, it can be understood that the inner sidewall of the reflecting cover 40 can be coated with a reflective coating in the above-mentioned embodiments. The reflective coating allows the reflecting cover 40 to reflect more infrared rays into the cooking cavity, which improves the utilization rate of the infrared rays, reduces the loss of infrared radiation energy, and improves the heating intensity of the food materials in the cooking cavity.

[0051] Embodiment Two:

[0052] On the basis of the above-mentioned embodiment one, this embodiment provides a cooking appliance 1, which is similar to the cooking appliance 1 in the above-mentioned embodiment one and has the same structure and functions. The difference between the two embodiments is that the cooking appliance 1 in this embodiment comprises a plurality of infrared heating elements 50 arranged in the heating cavity 60. Figure 7As shown, in the embodiment, the side wall of the inner pot 30 can be provided with a maximum capacity scale line K, and the cooking cavity can hold food materials up to the maximum capacity scale line K. When the amount of food materials in the cooking cavity exceeds the maximum capacity scale line K, the cooking effect on the food materials cannot be guaranteed, and the machine may also be damaged. In the embodiment, the area in the cooking cavity below the maximum capacity scale line K is referred to as a cooking area.

[0053] Further, in the embodiment, the extension line of the side wall of the first opening 61 intersects with the side wall of the inner pot 30 at a point J, and the point J is not lower than the maximum capacity scale line K and is located below the pot rim of the inner pot 30. That is, the point J can be located at the maximum capacity scale line K, or the point J can be located between the maximum capacity scale line K and the pot rim of the inner pot 30. Through the arrangement, the infrared rays radiated by the infrared heating element 50 can directly enter or enter the cooking area after being reflected by the reflecting cover 40, so that the heat radiated by the infrared heating element 50 is concentrated in the cooking area to heat the food materials in the cooking area, improve the cooking effect on the food materials, and reduce the influence on the structure above the inner pot 30.

[0054] Embodiment Three:

[0055] On the basis of the above-mentioned embodiment one, the embodiment provides a cooking appliance 1, as shown in Figure 8 and Figure 9 In the cooking appliance 1, the top end of the reflecting cover 40 extends towards the inner pot 30 to form a flange 41. Specifically, the top end of the reflecting cover 40 can extend towards the inner pot 30 along the horizontal direction to form the flange 41, or the top end of the reflecting cover 40 can extend towards the inner pot 30 along a target direction to form the flange 41. The target direction is a direction at a first included angle with the horizontal direction, and the first included angle can be 0-45°.

[0056] Further, in the embodiment, the projection of the flange 41 on the horizontal plane V is located within the projection range of the infrared heating element 50 on the horizontal plane V. Specifically, if the infrared heating element 50 is projected onto the horizontal plane V to form a projection A, the projection A occupies an area S on the horizontal plane V; if the flange 41 is projected onto the horizontal plane V to form a projection B, the projection B occupies an area F on the horizontal plane V. At this time, the projection of the flange 41 on the horizontal plane V being located within the projection range of the infrared heating element 50 on the horizontal plane V means that the area F is located within the area S.

[0057] When the flange 41 is not arranged on the reflector 40, part of the infrared rays radiated by the infrared heating element 50 will be radiated on the pot body 10 through the first opening 61. In this case, the energy loss is serious, and the temperature rise of the pot body 10 is increased. In the present embodiment, the flange 41 is arranged to reflect the infrared rays originally radiated on the pot body 10 into the cooking area, thereby improving the energy utilization of the infrared rays and reducing the energy loss. At the same time, the temperature rise of the pot body 10 is reduced, the occurrence of user scalding is alleviated, the circuit elements in the pot body 10 are protected, and the service life of the cooking appliance 1 is prolonged.

[0058] Embodiment Four

[0059] Based on the above-mentioned embodiment two, the present embodiment provides a cooking appliance 1, as shown in Figure 10 In the present embodiment, the infrared heating element 50 can be arranged in a circular tube shape. The extension line of the line between the end surface 411 of the flange 41 and the maximum capacity scale line K is tangent to the outer surface of the infrared heating element 50; that is, when a first straight line is made tangent to the outer surface of the infrared heating element 50 from the maximum capacity scale line K, the end surface 411 of the flange 41 is located on the first straight line.

[0060] When the infrared heating element 50 is arranged in a circular tube shape, it can heat the food in the cooking area by a ring heating method, which is beneficial to ensure the uniformity of the circumferential heat of the food. By arranging the end surface 411 of the flange 41 on the first straight line, the flange 41 can reflect more infrared rays originally radiated on the pot body 10 into the cooking area.

[0061] Of course, it can be understood that in the present embodiment, the infrared heating element 50 can be a graphite tube, a carbon tube or a metal tube with a coating. Preferably, the infrared heating element 50 can be a graphite tube. The graphite tube radiates infrared rays with shorter wavelength and higher penetration, and has higher heating efficiency for food.

[0062] Embodiment Five

[0063] Based on the above-mentioned embodiments, the present embodiment provides a cooking appliance 1, as shown in Figure 9 and Figure 10 In the cooking appliance 1, the axial section of the side wall of the reflector 40 is a parabola, the center of the infrared heating element 50 is located at the focus of the parabola, and the symmetry axis P of the parabola is arranged upwardly inclined toward the inner pot 30.

[0064] In the embodiment, the axial section of the side wall of the reflector 40 is provided in a parabolic structure, so that the first opening 61 is inclined towards the outer side wall of the inner pot 30. Further, the center of the infrared heating element 50 is located at the focal point of the parabola, and the symmetry axis P of the parabola is inclined upwards towards the inner pot 30, so that the reflector 40 can reflect more infrared rays in an inclined upward direction to above the cooking cavity, improving the heating effect on the upper food in the cooking cavity.

[0065] As shown in Figure 9 and Figure 10 , the axial section of the side wall of the inner pot 30 is inclined outwardly and forms an angle α with the horizontal plane V, the symmetry axis of the parabola forms an angle β with the horizontal plane V, and the difference between α and β is 80°-100°.

[0066] In the embodiment, when the difference between α and β is 80°-100°, the infrared rays radiated by the infrared heating element 50 can be approximately vertically irradiated on the outer side wall of the inner pot 30, which is beneficial to reduce the reflection of the infrared rays by the outer side wall of the inner pot 30, reduce the energy loss of the infrared rays, and improve the heating effect on the food in the cooking cavity.

[0067] As shown in Figure 9 and Figure 10 , in the embodiment, the bottom of the heating cavity 60 is provided with a second opening 62. By providing the second opening 62, the intensity of the infrared rays reflected by the reflector 40 to the lower part of the cooking cavity is reduced, and the occurrence of the food being burnt when the bottom heating element 70 and the infrared heating element 50 simultaneously heat the food in the lower part of the cooking cavity is alleviated.

[0068] Embodiment six:

[0069] On the basis of the above-mentioned embodiments, the present embodiment provides a cooking appliance 1, wherein a heat insulation piece 80 is arranged between the inner side wall of the pot body 10 and the outer side wall of the inner pot 30, and the heat insulation piece 80 is arranged outside the reflector 40. By arranging the heat insulation piece 80, the heat on the reflector 40 is blocked from being transmitted outwardly to the pot body 10, which is beneficial to reduce the temperature rise of the pot body 10 and alleviate the occurrence of the user being scalded, and at the same time, the circuit elements in the pot body 10 are protected, and the service life of the cooking appliance 1 is prolonged.

[0070] As shown in Figure 11 and Figure 9 , the top end of the heat insulation piece 80 and the side wall of the inner pot 30 form a third opening 810 corresponding to the first opening 61. By arranging the third opening 810, the infrared rays radiated by the infrared heating element 50 can pass through the first opening 61 and the third opening 810 and penetrate the side wall of the inner pot 30 to enter above the cooking cavity, so as to heat the food in the upper part of the cooking cavity.

[0071] As shown in Figure 10As shown, a gap is provided between the heat insulation component 80 and the reflector 40, forming an air insulation layer. By setting the air insulation layer, the heat insulation effect of the heat insulation component 80 is improved.

[0072] like Figure 11 and Figure 12 As shown, the thermal insulation element 80 can be a single, integral structure. Alternatively, as... ​ As shown, the heat insulation component 80 may include a first heat insulation component 81 and a second heat insulation component 82 disposed outside the reflector 40, with the bottom of the first heat insulation component 81 connected to the top of the second heat insulation component 82. When the heat insulation component 80 includes the first heat insulation component 81 and the second heat insulation component 82, the first heat insulation component 81 and the second heat insulation component 82 can be processed separately, resulting in greater processability.

[0073] Example 7:

[0074] Based on the above embodiments, this embodiment provides a cooking utensil 1, such as... ​ As shown, in this cooking appliance 1, the distance between the maximum capacity scale line K on the side wall of the inner pot 30 and the bottom of the inner pot 30 is H, and the distance H' between the infrared heating element 50 and the bottom of the inner pot 30 is 0.3H to 0.5H. In this embodiment, by setting the distance between the infrared heating element 50 and the bottom of the inner pot 30, the infrared heating element 50 can effectively heat the food in the upper part of the cooking cavity when different amounts of food are placed in the cooking cavity, ensuring the heating effect of the food.
