DETAILED DESCRIPTION

[0024] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0025] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides various specific processes and examples of materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0026] The oven 1000 according to the embodiment of the present invention will be described below with reference to the accompanying drawings.

[0027] The oven 1000 according to the embodiment of the present invention is as follows: Figure 1 As shown, the oven 1000 includes: a box body 100, a carrier 200 and a lifting assembly 300. The box body 100 defines a cooking cavity 100a inside, the carrier 200 is disposed in the cooking cavity 100a, and the lifting assembly 300 is used to drive the carrier 200 to move up and down in the cooking cavity 100a.

[0028] A cooking cavity 100a is defined inside the box body 100, and the cooking cavity 100a is used to accommodate food and cook the food. The food is placed on the object carrier 200 for cooking, and the lifting assembly 300 drives the object carrier 200 to move up and down in the cooking cavity 100a, so that the heating position of the food on the object carrier 200 and the degree of heat can be adjusted, making the heating temperature of the food more flexible and variable, effectively improving the heating uniformity and color uniformity of the food, thereby improving the baking effect of the food.

[0029] like Figure 1 and Figure 2 As shown, the lifting assembly 300 includes: an output part 1, a power part 2 and a transmission part 3. The output parts 1 are two and are respectively disposed on the left and right sides of the cooking cavity 100a to drive the object carrier 200 to move up and down. The power part 2 is disposed outside the cooking cavity 100a and is disposed in the center of the left and right sides relative to the two output parts 1. The transmission parts 3 are two and are respectively disposed on both sides of the power part 2. The two transmission parts 3 are respectively connected to the two output parts 1. The transmission part 3 includes a winding mechanism 31 and a rope 32. The rope 32 is connected between the winding mechanism 31 and the output part 1. The power part 2 drives the two winding mechanisms 31 to move synchronously, so that the ropes 32 on both sides are retracted and unreeled synchronously. The ropes 32 drive the output part 1 to move up and down through the retracted and unreeled movement.

[0030] The power of the lifting assembly 300 is transmitted through the power unit 2, transmitted through the transmission unit 3, and finally transmitted to the output unit 1 to drive the object carrier 200 to move up and down. The power unit 2 is arranged outside the cooking cavity 100a, and can control the lifting of the object carrier 200 in the cooking cavity 100a during the baking process, without the user opening the door to move the object carrier 200, saving the user's time and energy while avoiding wasting electricity, and effectively improving the intelligence and convenience of the oven 1000.

[0031] There is one power unit 2, two transmission units 3 disposed on the left and right sides of the power unit 2, and two output units 1 disposed on the left and right sides of the power unit 2. The two output units 1 drive the object carrier 200 to move up and down together, and the object carrier 200 is evenly stressed, which can improve the movement stability of the object carrier 200.

[0032] In addition, the power unit 2 is located in the middle of the two output units 1 and is centered relative to the two output units 1. The power output to the two output units 1 is consistent, which can improve the synchronization of the movement of the output units 1, and improve the synchronization of the lifting and lowering of the left and right ends of the carrier 200. The height difference between the left and right ends of the carrier 200 during the lifting process is reduced, the risk of overturning of the carrier 200 is reduced, and the working reliability of the oven 1000 is improved.

[0033] The transmission part 3 includes a winding mechanism 31 and a rope 32. The winding mechanism 31 is connected to the power part 2. One end of the rope 32 is connected to the winding mechanism 31, and the other end of the rope 32 is connected to the output part 1. The rope 32 can be wound on the winding mechanism 31. The power part 2 drives the winding mechanism 31 to rotate, so that the rope 32 is wound and unwound. The length of the rope 32 extending out of the winding mechanism 31 changes, which can drive the output part 1 to rise and fall.

[0034] Compared with structures such as a rack and pinion mechanism and a scissor-type lifting platform, the transmission part 3 is configured as a winding mechanism 31 and a rope 32. The transmission part 3 has a simple structure and is small in weight and volume. When the volume of the oven 1000 is the same, the winding mechanism 31 and the rope 32 occupy a smaller space, which can reduce the space occupied by the cooking cavity 100a. While achieving lightweighting of the oven 1000, it is also beneficial to increase the space of the cooking cavity 100a.

[0035] According to the oven 1000 of the embodiment of the present invention, by arranging the power unit 2 in the middle of the two output units 1, the synchronization of the movement of the output units 1 can be improved, the synchronization of the lifting and lowering of the left and right ends of the object carrier 200 can be improved, the height difference between the left and right ends of the object carrier 200 during the lifting and lowering process can be reduced, the overturning risk of the object carrier 200 can be reduced, and the working reliability of the oven 1000 can be improved. In addition, the structure of the transmission unit 3 is simple, and the winding mechanism 31 and the rope 32 occupy a small space, which is conducive to increasing the space of the cooking cavity 100a while achieving the lightweight of the oven 1000.

[0036] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the power unit 2 and the winding mechanism 31 are both arranged below the cooking cavity 100a. Figure 3 As shown, the transmission part 3 further includes: a fixed pulley 33, which is arranged above the output part 1, and the end of the rope 32 is connected to the output part 1 after passing through the fixed pulley 33 upwards.

[0037] In the related art, by merely arranging the winding mechanism below the output part, the winding of the rope can only drive the output part down, and the unwinding of the rope cannot drive the output part up under the action of gravity. In some embodiments of the present invention, by arranging the fixed pulley 33, the power direction can be changed, and the rope 32 applies force to the output part 1 from above the output part 1. The winding of the rope 32 can drive the output part 1 up, and the unwinding of the rope 32 can drive the output part 1 down under the action of gravity.

[0038] By arranging the fixed pulley 33, the power unit 2 and the wire winding mechanism 31 can be placed downward. Compared with arranging the power unit 2 and the wire winding mechanism 31 above the cooking cavity 100a, arranging the power unit 2 and the wire winding mechanism 31 below the cooking cavity 100a can reduce the pressure above the cooking cavity 100a, reduce the occurrence of the top of the cooking cavity 100a being compressed, collapsed and deformed, and extend the service life of the oven 1000.

[0039] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the winding mechanism 31 includes: a winding drum 311 and a transmission shaft 312, and the winding drum 311 is located below the output part 1. Figure 5 As shown, the drum 311 includes two wire baffles 3111 spaced apart along the axis of the drum 311 to form a wire winding groove 3112 for accommodating the rope 32 between the two wire baffles 3111. Figure 3 and Figure 4 As shown, the transmission shaft 312 extends from the power unit 2 to the drum 311 , and one end of the transmission shaft 312 is connected to the power unit 2 , and the other end is passed through the drum 311 , so that the power unit 2 drives the drum 311 to reel in and out the rope 32 through the transmission shaft 312 .

[0040] The winding mechanism 31 consists of two parts. The winding drum 311 is located below the output part 1 and is arranged opposite to the output part 1. The transmission shaft 312 is arranged near the power part 2 relative to the winding drum 311. The transmission shaft 312 and the output part 1 are staggered in the up and down directions. Therefore, the rope 32 is wound on the winding drum 311, and the transmission shaft 312 is only used for transmission between the power part 2 and the winding drum 311. With such a design, the rope 32 can be wound centrally below the output part 1, and the rope 32 will not slide to other positions far from the output part 1, which is conducive to the smooth winding and unwinding of the rope 32 and can improve the working reliability of the transmission part 3.

[0041] In addition, the transmission shaft 312 is inserted through the reel 311 to drive the reel 311 to rotate, which has a simple connection mode and reliable transmission, and can further improve the working reliability of the transmission part 3 .

[0042] like Figure 5 As shown, the drum 311 includes two wire baffles 3111 spaced apart along the axis of the drum 311 , thereby separating the inside and outside of the drum 311 , so as to limit the rope 32 in the winding groove 3112 formed by the two wire baffles 3111 , which is beneficial to the smooth winding and unwinding of the rope 32 .

[0043] In some embodiments of the present invention, Figure 3 As shown, the width L1 of the wire winding groove 3112 between the two wire blocking plates 3111 is greater than the width L2 of the wire passing groove 331 on the fixed pulley 33 .

[0044] The wire groove 331 of the fixed pulley 33 only needs to allow a single rope 32 to pass around, so the width L2 of the wire groove 331 on the fixed pulley 33 is narrow; while the width L1 of the winding groove 3112 between the two wire baffles 3111 is wider, which is conducive to winding more ropes 32 and can reduce the occurrence of the rope 32 escaping from the winding groove 3112.

[0045] In some embodiments of the present invention, Figure 5 As shown, a thread groove 3113 is formed on the peripheral wall surface of the drum 311 , and the thread groove 3113 is used for winding the rope 32 .

[0046] The thread groove 3113 extends along the axial direction of the winding drum 311. By setting the thread groove 3113, the rope 32 can be limited, so that the rope 32 can be wound and released in an orderly manner during the scaling process, which can reduce the occurrence of the rope 32 escaping from the winding groove 3112 and improve the working reliability of the transmission part 3.

[0047] In some embodiments of the present invention, Figure 4 and Figure 6 As shown, the power unit 2 is a dual-output shaft motor 2a, with output shafts extending toward the reels 311 on both sides, and the output shafts are connected to the transmission shaft 312 through a coupling 34.

[0048] The left and right sides of the dual-output shaft motor 2a are respectively provided with output shafts 21, and the output shafts 21 are connected to the transmission shaft 312 through a coupling 34. By providing the dual-output shaft motor 2a, the output shafts 21 of the dual-output shaft motor 2a are directly connected to the transmission shaft 312, and other transmission mechanisms can be omitted. On the one hand, the synchronous driving of the reels 311 on both sides can be better guaranteed, and on the other hand, the complexity of the mechanism can be reduced, saving manufacturing costs.

[0049] By connecting the transmission shaft 312 with the coupling 34, a complicated transmission mechanism and a situation where the transmission shaft 312 is too long and the torsion angle is too large can be avoided, thereby reducing the height difference of the baking tray caused by the asynchronism between the two ends.

[0050] In some embodiments of the present invention, Figure 3 As shown, the lifting assembly 300 further includes: a guide rod 4, the length of the guide rod 4 extends in the up-down direction, and the fixed pulley 33 is located above the guide rod 4. Figure 4 and Figure 6 As shown, the output part 1 includes a slider 11 , which is slidably matched with the guide rod 4 so as to be slidable along the length direction of the guide rod 4 , and the end of the rope 32 is connected to the slider 11 after being wound around the set pulley 33 .

[0051] The guide rod 4 extends in the up-down direction, and the guide rod 4 can play a supporting and guiding role. The slider 11 slides with the guide rod 4, so that the slider 11 can move stably in the up-down direction, thereby improving the movement stability and accuracy of the output part 1, thereby improving the stability of the lifting movement of the object carrier 200.

[0052] The rope 32 is wound around the drum 311, and the end of the rope 32 extends upward from the drum 311 to the fixed pulley 33. The rope 32 is wound around the set pulley 33 and then connected to the slider 11 downward. The rope 32 applies force to the slider 11 from above the slider 11. When the rope 32 is wound up, the slider 11 can be driven to rise. When the rope 32 is unwound, the slider 11 can be lowered under the action of gravity.

[0053] In some embodiments of the present invention, Figure 3 As shown, the object carrier 200 can move between the first position m and the second position n driven by the output part 1, and can stop at any position between the first position m and the second position n. This can be automatically adjusted according to the requirements of the food for the cooking height or the distance from the heating tube.

[0054] In some embodiments of the present invention, Figure 4 and Figure 7As shown, the front and rear sides of the slider 11 are respectively provided with a first through hole 111 and a second through hole 112 penetrating in the up and down directions. The portion of the rope 32 extending from the winding mechanism 31 toward the fixed pulley 33 is provided with the first through hole 111, and the end portion of the rope 32 extending from the fixed pulley 33 toward the slider 11 is the end of the rope 32 and is connected to the second through hole 112.

[0055] The portion of the rope 32 extending upward from the drum 311 to the fixed pulley 33 is penetrated by the first through hole 111, and the end of the rope 32 connected to the slider 11 after being set on the pulley 33 is passed through the second through hole 112 and connected to the slider 11. By providing the first through hole 111 on the slider 11, the rope 32 can be limited, and the situation of the rope 32 being deviated and escaped from the fixed pulley 33 can be improved, which is conducive to the smooth winding and unwinding of the rope 32, and the working reliability of the winding mechanism 31 can be improved. By providing the second through hole 112 on the slider 11, on the one hand, the rope 32 can be limited, and on the other hand, the stability of the connection between the rope 32 and the slider 11 can be improved.

[0056] By providing the first through hole 111 and the second through hole 112 on the slider 11, the slider 11 that drives the object 200 to move up and down is used to limit the rope 32. There is no need to provide an additional limiting member to limit the rope 32, which reduces the complexity of the structure, saves manufacturing costs, and helps to reduce the weight and volume of the lifting assembly 300.

[0057] In some embodiments of the present invention, Figure 7 As shown, the slider 11 includes two protrusions 114 spaced apart in the vertical direction, the first through hole 111 penetrates the two protrusions 114 in the vertical direction, and the second through hole 112 penetrates the two protrusions 114 in the vertical direction. This design can improve the limiting effect of the rope 32 while reducing the weight of the slider 11, which is conducive to the lifting and lowering movement of the slider 11 driven by the transmission part 3, and can reduce the manufacturing cost of the slider 11.

[0058] In some embodiments of the present invention, Figure 2 and Figure 8 As shown, the box body 100 includes a top wall 101, a bottom wall 102 and a side wall 103, and the top wall 101, the bottom wall 102 and the side wall 103 define a cooking cavity 100a; the power unit 2 and the winding mechanism 31 are both arranged below the bottom wall 102; the guide rod 4 and the fixed pulley 33 are both fixed on the side wall 103 and are located outside the cooking cavity 100a.

[0059] The power unit 2 and the winding mechanism 31 are arranged below the bottom wall 102, that is, arranged below the outside of the cooking cavity 100a, and the guide rod 4 and the fixed pulley 33 are also arranged outside the cooking cavity 100a, which can reduce the occupation of the internal space of the cooking cavity 100a, avoid interference with the object 200 and food inside the cooking cavity 100a, and improve the working reliability of the oven 1000. In addition, the power unit 2, the winding mechanism 31, the guide rod 4 and the fixed pulley 33 are arranged outside the cooking cavity 100a, which can reduce the damage to the structure caused by heat and steam in the cooking cavity 100a, which is conducive to extending the service life of the oven 1000.

[0060] In some embodiments of the present invention, Figure 2 and Figure 8 As shown, the box body 100 includes a top wall 101, a bottom wall 102 and a side wall 103, and the top wall 101, the bottom wall 102 and the side wall 103 define a cooking cavity 100a; the box body 100 also includes a bottom plate 104, which is located below the bottom wall 102 and is separated from the bottom wall 102, and the power unit 2 and the winding mechanism 31 are both fixed on the bottom plate 104.

[0061] The bottom plate 104 is located outside the cooking cavity 100a and below the cooking cavity 100a. Fixing the power unit 2 and the winding mechanism 31 on the bottom plate 104 can avoid occupying the internal space of the cooking cavity 100a, avoid interference with the load 200 and food inside the cooking cavity 100a, and reduce damage to the mechanism caused by heat and steam in the cooking cavity 100a. Fixing the power unit 2 and the winding mechanism 31 on the bottom plate 104 can avoid the cooking cavity 100a from being compressed, collapsed, and deformed, thereby extending the service life of the oven 1000. In some embodiments of the present invention, Figure 8 As shown, the winding mechanism 31 is fixed to the bottom plate 104 via a winding fixing seat 35, the fixed pulley 33 is fixed to the side wall 103 via a fixed pulley fixing seat 36, and the guide rod 4 is fixed to the side wall 103 via two guide rod fixing seats 41 spaced apart in the up and down directions.

[0062] In some embodiments of the present invention, Figure 6 As shown, the reel 311 is rotatably matched with the winding fixed seat 35 through the first bearing 37, the connecting shaft 332 passes through the set pulley 33 and is connected to the fixed pulley fixed seat 36, and the fixed pulley 33 is rotatably matched with the connecting shaft 332 through the second bearing 38.

[0063] In some embodiments of the present invention, Figure 1 As shown, the oven 1000 further includes: a top heating element 400, which is disposed above the outside of the cooking cavity 100a.

[0064] By setting up a lifting component 300 to drive the carrier 200 to move up and down in the cooking cavity 100a, the distance between the food on the carrier 200 and the top heating element 400 can be adjusted, making the heating temperature of the food more flexible and variable, effectively improving the heating uniformity and color uniformity of the food, thereby improving the baking effect of the food.

[0065] In some embodiments of the present invention, the oven 1000 further includes: a bottom heating element, which is arranged below the outside of the cooking cavity 100a and above the power unit 2 and the winding mechanism 31.

[0066] The lifting assembly 300 drives the object carrier 200 to move up and down, which can change the distance between the food on the object carrier 200 and the bottom heating element, effectively improving the heating uniformity and color uniformity of the food. The power unit 2 and the winding mechanism 31 are located below the bottom heater, which can reduce interference with the bottom heater. Optionally, the power unit 2 and the winding mechanism 31 are located outside the cooking cavity 100a, which can avoid interference with the object carrier 200 and food inside the cooking cavity 100a.

[0067] In some embodiments of the present invention, Figure 1 , Figure 8 and Fig. 9 As shown, the transmission part 3 is located outside the cooking cavity 100a, and the output part 1 includes an external structure 1a, an internal structure 1b and a connecting structure 1c. The external structure 1a is located outside the cooking cavity 100a and cooperates with the transmission part 3. The internal structure 1b is located in the cooking cavity 100a and cooperates with the object carrier 200. A avoidance groove 1031 extending vertically is provided on the side wall 103 of the cooking cavity 100a. The connecting structure 1c passes through the avoidance groove 1031 and connects the external structure 1a and the internal structure 1b.

[0068] The transmission part 3 is arranged outside the cooking cavity 100a, which can reduce the occupation of the internal space of the cooking cavity 100a, avoid interference with the carrier 200 and food inside the cooking cavity 100a, and improve the working reliability of the oven 1000.

[0069] The external structure 1a of the output part 1 is located outside the cooking cavity 100a, and the internal structure 1b of the output part 1 is located inside the cooking cavity 100a. The external structure 1a and the internal structure 1b are connected by a connecting structure 1c. The transmission part 3 is connected to the external structure 1a. The external structure 1a, driven by the transmission part 3, drives the internal structure 1b to drive the object carrier 200 to move up and down. The connecting structure 1c passes through the side wall 103 of the cooking cavity 100a to connect the external structure 1a located outside the cooking cavity 100a and the internal structure 1b located inside the cooking cavity 100a. The side wall 103 of the cooking cavity 100a is provided with an avoidance groove 1031 for the connecting structure 1c to pass through.

[0070] By passing the output part 1 through the side wall 103 of the cooking cavity 100a, the external structure 1a of the output part 1 and the internal structure 1b of the output part 1 are respectively placed inside and outside the cooking cavity 100a, so that the object carrier 200 can only cooperate with the output part 1 inside the cooking cavity 100a, without having to extend the object carrier 200 out of the cooking cavity 100a to cooperate with the output part 1 outside the cooking cavity 100a. The object carrier 200 is a replaceable part, which is convenient for flexible use and can improve the application range of the oven 1000.

[0071] It is understandable that the external structure 1a needs to cooperate with the transmission part 3 and has a relatively large volume, and the internal structure 1b needs to cooperate with the object carrier 200 and has a relatively large volume. Therefore, by providing a smaller connecting structure 1c connected to the external structure 1a and the internal structure 1b respectively, and the connecting structure 1c passes through the side wall 103 of the cooking cavity 100a, the volume of the avoidance groove 1031 opened on the side wall 103 of the cooking cavity 100a can be reduced, thereby reducing the leakage of steam, heat, etc. in the cooking cavity 100a from the avoidance groove 1031.

[0072] In some embodiments of the present invention, Fig. 9 and Fig.10 As shown, a matching groove 113 opened upward is provided on the external structure 1a, and the connecting structure 1c is inserted into the matching groove 113 from top to bottom, and the upper end of the connecting structure 1c is connected to the internal structure 1b.

[0073] like Fig. 9 As shown, the matching groove 113 and the connecting structure 1c are jointly arranged in the avoidance groove 1031 to connect the external structure 1a and the internal structure 1b. The matching of the connecting structure 1c and the external structure 1a is simple. After the connecting structure 1c is inserted into the matching groove 113 from top to bottom, it can be fixed relative to the external structure 1a under the action of gravity. The external structure 1a is always connected to the connecting structure 1c during the up and down movement.

[0074] In other embodiments of the present invention, Fig.10 As shown, the connection structure 1c and the built-in structure 1b are integrally formed.

[0075] The connecting structure 1c and the built-in structure 1b are an integrally formed part, which can improve the structural stability of the connecting structure 1c and the built-in structure 1b, and is beneficial to improving the working reliability of the transmission part 3.

[0076] In some embodiments of the present invention, Figure 4 and Figure 8As shown, the lifting assembly 300 also includes: a guide rod 4, which is located outside the cooking cavity 100a and extends in the up and down direction. The external structure 1a is a slider 11 and is slidably matched with the guide rod 4 so as to be slidable along the length direction of the guide rod 4, and the end of the rope 32 is connected to the slider 11 after being wrapped around the set pulley 33.

[0077] The guide rod 4 extends in the up-down direction, and the guide rod 4 can play a supporting and guiding role. The slider 11 slides with the guide rod 4, so that the slider 11 can move stably in the up-down direction, thereby improving the movement stability and accuracy of the output part 1, thereby improving the stability of the lifting movement of the object carrier 200.

[0078] In some embodiments of the present invention, the slider 11 is a ball-type slider. During the lifting process, the ball contacts the guide rod 4, and the friction resistance is small. The slider 11 can be smoothly lifted up and down on the guide rod 4, which is beneficial to reducing the height deviation of the left and right sliders 11.

[0079] In some embodiments of the present invention, Fig. 9 and Fig.10 As shown, the built-in structure 1 b is a support bar 12 , which extends in the front-rear direction. The object carrier 200 is a baking tray or a grill, and both ends are placed on the support bar 12 .

[0080] The matching mode of the object carrier 200 and the support bar 12 is simple, and the operations of placing the object carrier 200 on the support bar 12 and removing the object carrier 200 are simple, and the object carrier 200 is easy to use.

[0081] In some embodiments of the present invention, Fig. 9 and Fig.10 As shown, a receiving groove 121 extending along the length direction of the supporting bar 12 is formed at the top end thereof, and downwardly protruding bosses 201 are respectively provided on both side edges of the object carrier 200 , and the bosses 201 are embedded and matched with the receiving groove 121 .

[0082] The object carrier 200 is embedded and matched with the convex platform 201 and the receiving groove 121 on the support bar 12 , so that the arrangement stability of the object carrier 200 can be improved, and the object carrier 200 can be moved up and down under the drive of the support bar 12 .

[0083] The boss 201 is easily matched with the receiving groove 121. After the boss 201 is inserted into the matching groove 113 from top to bottom, it can be fixed relative to the support bar 12 under the action of gravity. The object carrier 200 always remains connected to the support bar 12 during the lifting and moving process.
