[0036] The inner wall of the steam oven is usually provided with a heating tube to heat the food inside the inner tank through the radiant heat emitted by the heating tube. The existing heating tube is usually fixed in the inner tank. When cooking food of different sizes and types, due to the different distances between the heating tube and the food, it may be difficult to control the temperature of the food heated by the heating tube, thereby affecting the cooking effect.
[0037] In order to solve the above problems, Figures 1 to 5 As shown, the utility model first provides a heating device to accurately control the heating temperature of food materials and improve the cooking effect.
[0038] like Figure 1 As shown, the heating device can be used in a steam oven, which includes an inner container 4, and the heating device is arranged on the inner container 4. The heating device can be arranged on the top wall 41 of the inner container 4 as shown in the figure, or on the bottom wall 42, the rear wall 43 or the left and right side walls 44 of the inner container 4, and the installation method of the heating device is similar, as long as it can heat the food in the inner container 4. For the convenience of description, the following description takes the case where the heating device is arranged on the top wall of the inner container 4 as an example.
[0039] like Figure 1 As shown, specifically, the heating device includes a heating component 1 and a driving component 2, wherein: the heating component 1 includes a heating element 11 for heating the interior of the inner pot 4, the heating element 11 includes a fixed section 111 and a heating section 112 connected to each other, the fixed section 111 is connected to the inner pot 4, and the heating section 112 can be flipped relative to the fixed section 111; the driving component 2 includes a telescopic component 21, at least a part of the telescopic component 21 is located inside the inner pot 4 and connected to the heating section 112, the telescopic component 21 can extend or retract toward the interior of the inner pot 4 to drive the heating section 112 to flip relative to the fixed section 111.
[0040] In the heating device provided by the embodiment of the utility model, the heating element 11 is connected to the inner pot 4 through the fixed section 111, and can be electrically connected to the power supply, circuit board and other electrical components in the steam oven through the fixed section 111 to control the heating power of the heating section 112; during the cooking process, the food to be cooked is placed inside the inner pot 4, and when it is necessary to control the heating element 11 to approach the food, the telescopic member 21 is controlled to extend toward the inside of the inner pot 4, and drive the heating section 112 to move relative to the fixed section 111. Figure 1 The -Z direction shown is flipped so that the heating section 112 is close to the food; when the heating element 11 needs to be controlled to be away from the food, the telescopic member 21 is controlled to retract and drive the heating section 112 to move relative to the fixed section 111. Figure 1 The +Z direction flip shown makes the heating section 112 away from the food; thus, the distance between the heating element 11 and the food can be conveniently adjusted through the telescopic member 21 during the cooking process, and the heating temperature of the heating element 11 for food of different sizes and types inside the inner pot 4 can be accurately controlled to improve the cooking effect.
[0041] The heating assembly 1 may include one, two or more heating elements 11. Each heating element 11 generally includes two fixed sections 111 and one heating section 112, and two ends of the heating section 112 are connected to the two fixed sections 111 respectively.
[0042] Furthermore, when the heating element 11 is disposed on the top wall 41 of the inner pot 4, the fixed section 111 can be connected to the upper end of the rear wall 43 of the inner pot 4, and a number of first through holes corresponding to the number of the fixed sections 111 are provided on the rear wall 43 of the inner pot 4 for the fixed sections 111 to pass through; alternatively, the fixed section 111 can also be connected to the top wall 41 of the inner pot 4.
[0043] like Figure 1 As shown, in the illustrated embodiment, the heating element 11 further includes a bending section 113, the two ends of the bending section 113 are respectively connected to the fixed section 111 and the heating section 112, and the heating section 112 is flipped relative to the fixed section 111 through the bending section 113. The bending section 113 has a certain deformation capacity, so that the heating section 112 and the fixed section 111 are reliably connected, and the heating section 112 can be flipped relative to the fixed section 111 along the ±Z direction, ensuring that the heating section 112, the bending section 113 and the fixed section 111 will not be broken.
[0044] Among them, the number of bending sections 113 is set corresponding to the fixed sections 111. When the number of fixed sections 111 is two, the number of bending sections 113 is also two. The two bending sections 113 are respectively connected to the two fixed sections 111, and the ends of the two bending sections 113 away from the fixed sections 111 are respectively connected to the two ends of the heating section 112.
[0045] In another embodiment, while ensuring that the heating section 112 can work normally, the heating section 112 can also be rotatably connected to the fixed section 111 to achieve the flipping of the heating section 112 relative to the fixed section 111.
[0046] like Figure 1 and Figure 3As shown, during the flipping process of the heating section 112 relative to the fixed section 111, the fixed section 111 may be tilted or shaken relative to the inner liner 4. Therefore, in order to improve the stability of the heating element 11, the heating device also includes a sealing member 3, which is arranged at one end of the fixed section 111 connected to the inner liner 4. The sealing member 3 can be arranged between the fixed section 111 and the inner wall of the first through hole, or it can be sleeved on the part of the fixed section 111 extending out of the inner liner 4 through the first through hole and fit with the inner liner 4, so as to buffer the fixed section 111 and reduce the tilting or shaking of the fixed section 111 relative to the inner liner 4. At the same time, the sealing member 3 can also seal the first through hole to prevent the hot air in the inner liner 4 from leaking through the first through hole. Among them, the sealing member 3 can be set as a rubber member or a silicone member, and the rubber member and the silicone member have strong deformation ability and low cost.
[0047] like Figure 1 As shown, since the temperature of the heating section 112 is high during operation, the heating assembly 1 further includes a connecting member 12 disposed on the heating section 112, and the connecting member 12 is connected to the telescopic member 21. The connecting member 12 can prevent the telescopic member 21 from being damaged by contacting the high-temperature heating section 112 for a long time, thereby extending the service life of the driving assembly 2.
[0048] In the illustrated embodiment, the heating section 112 includes a plurality of U-shaped tubes arranged at intervals along the ±X direction, and the plurality of U-shaped tubes are connected in sequence, and the U-shaped tubes at both ends are respectively connected to the two fixed sections 111. The connector 12 extends along the ±X direction and is connected to each U-shaped tube to improve the strength of the heating section 112. The number of connectors 12 may be one, two or more, and the plurality of connectors 12 are arranged at intervals along the ±Y direction. Of course, in other embodiments, the heating section 112 may also be set to other regular or irregular structures such as a spiral structure, as long as the food inside the inner pot 4 can be evenly heated, and the embodiment of the utility model is not specifically limited here.
[0049] like Figure 1 As shown, when the number of the connecting member 12 is one, the connecting member 12 is arranged at one end of the heating section 112 away from the fixed section 111. When the number of the connecting member 12 is multiple, the telescopic member 21 is connected to the connecting member 12 which is farthest from the fixed section 111. It can be understood that the larger the distance between the connecting member 12 and the fixed section 111, the smaller the force required to drive the heating section 112 to flip relative to the fixed section 111, so that it is easy to control the flipping of the heating section 112 relative to the fixed section 111, and the flipping accuracy can also be improved.
[0050] like Figure 1 to Figure 2As shown, since the heating component 1 will block part of the top wall 41 of the inner tank 4 in the assembled state, the user cannot clean the top wall 41 and the oil stains on the side of the heating component 1 facing the top wall 41. Therefore, the connecting piece 12 is detachably snap-connected with the telescopic piece 21. Specifically, the telescopic piece 21 includes a buckle 213, and the buckle 213 is provided with a slot, and the connecting piece 12 can be snapped into the slot of the buckle 213 to achieve a reliable connection between the heating section 112 and the telescopic piece 21. When it is necessary to clean the inner wall of the inner tank 4 and the heating component 1, the connecting piece 12 can be disengaged from the buckle 213, so that the user can remove the heating component 1 from the inner tank 4 and then clean the top wall 41 of the inner tank 4 and the heating component 1, and the disassembly and assembly process is simple and convenient, which is convenient for the user to operate.
[0051] like Figure 3 As shown, the driving assembly 2 further includes a driving member 22, which is disposed on the outer wall of the inner liner 4 and can drive the telescopic member 21 to extend or retract toward the inside of the inner liner 4. Since the temperature inside the inner liner 4 is usually high, arranging the driving member 22 on the outer wall of the inner liner 4 can prevent the driving member 22 from being damaged by being in a high temperature environment for a long time, thereby extending the service life of the driving member 22.
[0052] like Figures 4 to 5 As shown, the telescopic member 21 includes a telescopic section 211 and a connecting section 212. The connecting section 212 is located outside the inner liner 4 and connected to the driving member 22. The telescopic section 211 is connected to the connecting section 212 and can pass through the inner liner 4; the connecting section 212 can slide close to or away from the outer wall of the inner liner 4, so that the telescopic section 211 extends toward or retracts inside the inner liner 4. Specifically, the top wall of the inner liner 4 is provided with a second through hole, and the telescopic section 211 can slide from the connecting section 212 through the second through hole and extend into the inner liner 4. The driving member 22 can drive the connecting section 212 to slide along the -Z direction close to the outer wall of the inner liner 4, so that the telescopic section 211 slides along the -Z direction with the connecting section 212, and the telescopic section 211 extends toward the inside of the inner liner 4; the driving member 22 can also drive the connecting section 212 to slide along the +Z direction away from the outer wall of the inner liner 4, so that the telescopic section 211 slides along the +Z direction with the connecting section 212, and the telescopic section 211 retracts. The size of the connecting section 212 is larger than that of the second through hole to limit the range of motion of the telescopic section 211 and prevent the telescopic section 211 from completely falling into the inner tank 4 through the second through hole, causing the heating section 112 to accidentally flip relative to the fixed section 111, thereby improving the safety of the heating component 1.
[0053] like Figures 4 to 5As shown, in the illustrated embodiment, there are two telescopic sections 211, and the two telescopic sections 211 are respectively connected to the two ends of the connecting section 212, and the driving member 22 is located between the two telescopic sections 211. Specifically, when the telescopic lengths of the two telescopic sections 211 are the same, the two telescopic sections 211 are arranged at intervals along the ±X direction; when the telescopic lengths of the two telescopic sections 211 are different, the two telescopic sections 211 can be arranged at intervals along the ±Y direction, and the telescopic section 211 with a longer telescopic length is located in the +Y direction of the telescopic section 211 with a shorter telescopic length. The connection of the two telescopic sections 211 with the heating section 112 or the connecting member 12 can improve the stability and reliability of the heating section 112 during operation; at the same time, the two telescopic sections 211 are respectively located on both sides of the driving member 22, which can also improve the balance of the telescopic section 211 driving the heating section 112 to flip relative to the fixed section 111. Thereby, the use safety of the heating assembly 1 is further improved, and it will not cause difficulty in disassembly and assembly between the telescopic section 211 and the heating section 112 or the connecting member 12, which is convenient for user operation.
[0054] Of course, in other embodiments, while ensuring reliable connection between the telescopic section 211 and the heating section 112 or the connecting member 12, the number of the telescopic sections 211 may be one, three, four or more, and the embodiments of the present invention do not impose any specific restrictions thereon.
[0055] like Figures 4 to 5 As shown, in the illustrated embodiment, the driving member 22 includes an electromagnet 221 and a magnet 222, the electromagnet 221 is arranged on the outer wall of the inner container 4, and the magnet 222 is arranged on the connecting section 212; the electromagnet 221 can be positively or negatively charged to apply an adsorption force or a repulsion force to the magnet 222, so that the connecting section 212 slides together with the magnet 222 to approach or move away from the outer wall of the inner container 4. Among them, when the electromagnet 221 is positively charged, an adsorption force can be applied to the magnet 222, so that the magnet 222 drives the connecting section 212 to slide close to the outer wall of the inner container 4, that is, the magnet 222 drives the connecting section 212 and the telescopic section 211 to slide together along the -Z direction; when the electromagnet 221 is negatively charged, a repulsion force is applied to the magnet 222, so that the magnet 222 drives the connecting section 212 to slide away from the outer wall of the inner container 4, that is, the magnet 222 drives the connecting section 212 and the telescopic section 211 to slide together along the +Z direction. Alternatively, when the electromagnet 221 is negatively charged, a repulsive force may be applied to the magnet 222, so that the magnet 222 drives the connecting section 212 and the telescopic section 211 to slide together along the +Z direction; and when the electromagnet 221 is positively charged, an adsorption force may be applied to the magnet 222, so that the magnet 222 drives the connecting section 212 and the telescopic section 211 to slide together along the -Z direction.
[0056] Furthermore, changing the magnitude of the current passing through the electromagnet 221 can change the magnitude of the adsorption force or repulsion force applied by the electromagnet 221 to the magnet 222, thereby adjusting the distance between the magnet 222 and the electromagnet 221, so as to adjust the length of the telescopic section 211 extending toward the inside of the inner pot 4, thereby adjusting the flipping angle of the heating section 112 relative to the fixed section 111. The user can conveniently adjust the flipping angle of the heating section 112 relative to the fixed section 111 through the cooperation of the electromagnet 221 and the magnet 222 according to cooking needs, and the driving structure is simple, the number of parts is small, and the cost is low.
[0057] In another embodiment, the driving member 22 includes a motor and a screw connected to the output shaft of the motor, and the connecting section 212 is provided with a threaded hole that is threadedly matched with the screw, and the motor can drive the screw to rotate to drive the connecting section 212 to slide relative to the screw to approach or move away from the outer wall of the inner container 4. Of course, in other embodiments, the driving member 22 can also be set as an electric guide rail, a cylinder, or other element that can drive the connecting section 212 to slide linearly and reciprocatingly, and the embodiment of the utility model is not specifically limited here.
[0058] like Figure 1 and Figure 3 As shown, the embodiment of the utility model also provides a steam oven, comprising an inner pot 4 and the above-mentioned heating device, so as to accurately control the heating temperature of the heating element 11 on the ingredients of different sizes and types in the inner pot 4, thereby improving the cooking effect.
[0059] Of course, in other embodiments, the heating device can also be used in ovens, air fryers and other cooking appliances that use the radiant heat emitted by the heating device to heat food, and the embodiments of the utility model are not specifically limited here.
[0060] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0061] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
