[0002] An oven is a sealed electrical appliance used to bake food or dry products, and is divided into household appliances and industrial ovens. Among them, a household oven (i.e., an electric oven) can be used to process some pasta and other foods. The electric oven is an electric heating appliance that uses the radiant heat emitted by electric heating elements to bake food. With it, we can make roasted chickens, roasted ducks, bake bread, pastries, etc. According to the different needs of baked foods, the temperature of the electric oven can generally be adjusted within the range of 50-250 °C.

[0003] Currently, the oven usually includes a heating chamber, and there are heating radiation tubes above the heating chamber for radiating heat to the food. However, since there is only one heating chamber, usually only one kind of food can be cooked at a time, because different foods require different heating temperatures and durations, and even if the heating temperature and duration are the same, the foods in the same heating chamber are prone to flavor cross-talk, and the use effect is poor.

[0052] A positioning cylinder 16 with a rectangular longitudinal section is horizontally arranged on the outer wall of the oven door 7, and a movable cylinder 17 is movably sleeved in the positioning cylinder 16. The outer wall of the movable cylinder 17 is movably fitted to the inner wall of the positioning cylinder 16, and a C-shaped operating handle 18 is arranged at one end of the movable cylinder 17, and the other end is movably located in the inner cavity of the positioning cylinder 16, and the opening of the operating handle 18 faces the oven door 7. The operating handle 18 is located between the free end of the oven door 7 and the positioning cylinder 16, and the positioning cylinder 16 located on one of the oven doors 7 is higher or lower than the positioning cylinder 16 located on the other oven door 7.

[0053] The movable cylinder 17 is hollow, and a connecting portion 19 is provided at one end of the operating handle 18. The connecting portion 19 is hinged to the middle of one end of the movable cylinder 17 close to the operating handle 18. An L-shaped or L-shaped driving portion 20 is provided on the side of the connecting portion 19 away from the operating handle 18. One end of the driving portion 20 is fixedly connected to the connecting portion 19, and the other end can move to fit the bottom of the inner cavity of the movable cylinder 17 or separate from the bottom of the inner cavity of the movable cylinder 17.

[0054] a first elastic member 21, wherein the first elastic member 21 is located between the inner wall of the movable cylinder 17 and the free end of the driving portion 20;

[0055] On the inner wall of the movable cylinder 17, a linkage 22 with a downward-opening V shape is also hingedly arranged. On the outer sides of the two ends of the linkage 22, a first linkage part 23 and a second linkage part 24 are horizontally arranged respectively. The first linkage part 23 is movably abutted against the upper side of the free end of the driving part 20, and there is a set distance between the first linkage part 23 and the first elastic part 21. A second elastic part 25 is arranged between the top of the first linkage part 23 and the inner wall of the movable cylinder 17;

[0056] On the upper side of the end of the second linkage part 24 away from the linkage 22, a first locking body 26 is arranged. The upper side of the end of the first locking body 26 away from the linkage 22 is arc-shaped, and the side close to the linkage 22 is perpendicular to the second linkage part 24. The first locking body 26 is located outside the movable cylinder 17;

[0057] On the inner wall of the positioning cylinder 16, an annular termination ring 27 is arranged, and the termination ring 27 is opposite to the end of the movable cylinder 17 located in the positioning cylinder 16;

[0058] On the inner wall of the positioning cylinder 16, four guide rails 28 are vertically arranged. Two of the guide rails 28 are located on the side of the positioning cylinder 16 close to the oven door 7, and the other two guide rails 28 are located on the side of the positioning cylinder 16 away from the oven door 7. The termination ring 27 is located between the four guide rails 28 and the movable cylinder 17;

[0059] A second locking body 29 is vertically slidably arranged in the positioning cylinder 16. Four slots matching with the four guide rails 28 are vertically opened on both sides of the second locking body 29, and both sides of the second locking body 29 are movably attached to the inner wall of the positioning cylinder 16. The bottom of the side of the second locking body 29 close to the termination ring 27 is arc-shaped, and the side away from the termination ring 27 is vertical. A third elastic part 30 is arranged between the top of the second locking body 29 and the top of the positioning cylinder 16;

[0060] On the inner wall of the positioning cylinder 16, four support blocks 31 are arranged. At the four corners of the top of the second locking body 29, there are mating blocks 32 located above the four support blocks 31. When the mating blocks 32 are abutted against the tops of the support blocks 31, the vertical part of the second locking body 29 can be attached to the vertical part of the first locking body 26.

[0061] A through hole 33 is vertically formed in the middle of the movable cylinder 17 and the middle of the linkage member 22. A limiting rod 34 passing through the through hole 33 is vertically arranged on the inner wall of the positioning cylinder 16. Two protective columns 35 are horizontally arranged on the inner wall of the movable cylinder 17. The linkage member 22 is located between the two protective columns 35. When the protective column 35 abuts against the limiting rod 34, the distance between the operating handle 18 and the positioning cylinder 16 is the largest.

[0062] A indicating column 36 is also horizontally arranged in the middle of the movable cylinder 17. The limiting rod 34 is located between the indicating column 36 and the protective column 35. When the indicating column 36 abuts against the limiting rod 34, the vertical part of the second locking body 29 fits against the vertical part of the first locking body 26. And when the upper side of the first linkage part 23 or the upper side of the linkage member 22 abuts against the lower side of the indicating column 36, the second locking body 29 and the first locking body 26 are in a separated state, and the bottom of the second linkage part 24 abuts against the bottom of the inner cavity of the positioning cylinder 16.

[0063] A protective member 37 is arranged at one end of the operating handle 18 away from the positioning cylinder 16. The opening of the operating handle 18 faces the protective member 37, and there is a set distance between the protective member 37 and the end of the operating handle 18 close to the positioning cylinder 16. The protective member 37 is movably attached to the outer side of the oven door 7.

[0064] An L-shaped protective body 38 is arranged on the oven door 7. A U-shaped opening facing downward is formed between the protective body 38 and the outer wall of the oven door 7. A protective part 39 is vertically arranged on the upper side of the end of the operating handle 18 away from the positioning cylinder 16. One side of the protective part 39 fits against the outer wall of the oven door 7, and the side away from the oven door 7 is movably attached to the protective body 38.

[0065] A double-door and double-chamber oven provided by the present invention can, when in use, separately turn on and off the first heating structure 3 and the second heating structure 4, and at the same time, the opening temperatures and durations of the two heating structures can also be separately controlled. Thus, when in actual use, if it is necessary to heat two kinds of foods simultaneously, different ingredients can be added to the first heating structure 3 and the second heating structure 4 respectively for heating; however, if heating the same kind of food, the same ingredients can be added to the first heating structure 3 and the second heating structure 4 simultaneously to improve the heating efficiency. The two oven doors 7 respectively control the opening and closing of the first heating chamber and the second heating chamber, and the opening and closing of the two oven doors 7 do not affect each other. Therefore, when one is heating, the other can be used to put in or take out ingredients, thus making the use effect better. The partition board 2 is made of a high-temperature-resistant food-grade material, which can preferably prevent the temperature and smell of the first heating chamber and the second heating chamber from being cross-moved, ensuring the heating quality.

[0066] Moreover, since the position of the partition board 2 can slide in the box body 1, during actual use, the capacity of the first heating chamber or the second heating chamber can also be selected and adjusted according to actual use requirements, or only one of the heating chambers can be used, so that the actual use requirements can be met and the applicable range is wider.

[0067] On the upper and lower sides of the opening side of the box body 1, there are strip-shaped positioning magnets 8. The positioning magnets 8 can magnetically attract the oven door 7, and when opening the oven door 7, only the oven door 7 needs to be pulled outwards to separate the oven door 7 from the positioning magnets 8, which is simple and convenient. At the same time, according to the actual situation, food-grade high-temperature-resistant silica gel or rubber can also be arranged on the inner side of the oven door 7 to increase the tightness between the oven door 7 and the box body 1.

[0068] If, when in use, the temperatures of the first heating structure 3 and the second heating structure 4 in the first heating chamber and the second heating chamber need to be relatively high, the first auxiliary pipe 9 can also be opened for auxiliary heating at this time. The spiral-shaped first auxiliary pipe 9 can cross over the partition board 2 to heat the first heating chamber and the second heating chamber. At the same time, it is embedded in the top of the box body 1, that is, a groove matching the first auxiliary pipe 9 is opened at the top of the box body 1. In this way, the top of the partition board 2 still abuts against the inner cavity wall of the box body 1, ensuring the blocking effect on the first heating chamber and the second heating chamber, and when it is necessary to move the partition board 2, the first auxiliary pipe 9 can not affect the normal movement of the partition board 2.

[0069] Similarly, the second auxiliary tube 11 in the first make way groove 10 and the third auxiliary tube 13 in the second make way groove 12 can not affect the normal movement of the blocking plate 2; and when heating food, the second auxiliary tube 11 and the third auxiliary tube 13 can also heat the food from below, thereby improving the comprehensiveness of food heating and improving the cooking quality and effect.

[0070] When in use, the two sides of the grill or the grill can be respectively assumed or abutted on the first support member 5 and the second support member 6, but if the two chambers need to be combined for use (for example, in restaurants, most of the large space heating is needed, and only a few times do two chambers need to be used), the blocking plate 2 can be moved along the guide body 14, and the blocking plate 2 is movably connected to the guide body 14 through the matching grooves 15 at its four corners, so it can be moved to a certain side of the inner wall of the box body 1, and after stopping the movement of the blocking plate 2, there is still a large interaction force between the blocking plate 2 and the guide body 14, which can maintain the position stability of the blocking plate 2; similarly, when the blocking plate 2 is used in the middle of the box body 1, the position of the blocking plate 2 is also stable (static friction between the guide body 14). Not only that, when the space in the box body 1 is used as a whole, the upper and lower sides of the blocking plate 2 will not block the first heating structure 3, the second heating structure 4, the first auxiliary tube 9, the second auxiliary tube 11 and the third auxiliary tube 13, so it will not cause heat waste, and the use effect is better. The first heating structure 3 , the second heating structure 4 , the first auxiliary tube 9 , the second auxiliary tube 11 and the third auxiliary tube 13 are preferably conventional electric heating tubes.

[0071] When the oven door 7 is opened, if there is a lot of water vapor in the oven, heat waves are easily generated, and even burn the user's hands. At this time, the user can extend the length of the operating handle 18 and extend the used operating handle 18 to the outside of another closed oven door 7, or to the opened cabinet 1 (without heat waves or radiation). This can not only save more effort (leverage effect), but also because the hand opening the oven door 7 is not facing the opened oven door 7 and has a greater distance from the edge of the opened oven door 7, it can also well prevent the hand from being burned by steam, and the use is safer. The specific method of use is as follows:

[0072] Attach Figure 7For example, the operator holds the operating handle 18 and rotates it downward, causing the connecting portion 19 to rotate, and at the same time the left side of the driving portion 20 rotates upward. During this process, the first elastic member 21 is further elastically compressed, and the first linkage portion 23 is rotated upward, and at the same time the second elastic member 25 is further elastically compressed; the first linkage portion 23 drives the linkage member 22 to rotate counterclockwise, so the second linkage portion 24 rotates downward until the first locking body 26 is separated from the second locking body 29, that is, the first locking body 26 is located below the second locking body 29. In this state, the upper side of the first linkage portion 23 or the linkage member 22 contacts the lower side of the indicator column 36. side, and the lower side of the second linkage part 24 abuts against the lower side of the inner wall of the positioning tube 16, and multiple structures are in contact at the same time; then the operating handle 18 can be kept turned downward and pulled to the right for a certain distance, such as 0.5-1cm, and then the operating handle 18 is released, and the operating handle 18 and the first linkage part 23 move downward under the elastic action of the first elastic member 21 and the second elastic member 25, and the first locking body 26 moves upward at this time, but the first locking body 26 and the second locking body 29 will not be locked with each other at this time, so the operating handle 18 can be continuously pulled to the right, and at the same time, the entire movable tube 17 is driven to move to the right through the connecting part 19;

[0073] During the activity, since the limiting rod 34 passes through the clearance hole 33, the limiting rod 34 does not affect the normal activity of the movable cylinder 17 and the linkage 22; the operating handle 18 is continuously pulled until the protective column 35 contacts the limiting column, which means that the operating handle 18 has been stretched to the limit and cannot be pulled forward. At the same time, the operating handle 18 is also far away from the edge of the oven door 7 to be opened, which can be 20-25cm according to the actual situation. Then the operating handle 18 is pulled outward, and the oven door 7 can be opened through the operating handle 18, the movable cylinder 17 and the positioning cylinder 16. Since the distance between the operating handle 18 and the hinge between the oven door 7 to be opened and the box body 1 is larger, it is more labor-saving to open the oven door 7. In the above operation process, the oven door 7 is subjected to the suction of the positioning magnet 8, that is, it is in a closed state with the box body 1 until the oven door 7 is opened by the operating handle 18.

[0074] Since there is a gap of 20-25 cm between the operator's hand and the edge of the opened oven door 7, firstly, a lot of steam cannot act on the hand, and even if it acts on the hand, due to the long distance and the low temperature of the outside air compared to the oven, the steam can cool down quickly, thereby preventing the user from being burned and fully ensuring the safety of use.

[0075] After use, simply insert the movable cylinder 17 into the positioning cylinder 16 by operating the handle 18. During this insertion process, it remains unobstructed continuously (the widths of the second linkage part 24 and the first locking body 26 are relatively small and can pass through or pass by the end ring 27) until the first locking body 26 abuts against the second locking body 29. The first locking body 26 abuts against the lower arc side of the second locking body 29 through its arc-shaped upper side. Therefore, when the handle 18 continues to drive the movable cylinder 17 into the positioning cylinder 16, the first locking body 26 receives a downward acting force, and the second locking body 29 also receives a downward acting force. So both the third elastic member 30 and the second elastic member 25 are compressed. In this embodiment, the deformation of the third elastic member 30 is the main one (with a thinner diameter), and the second elastic member 25 undergoes a very small elastic deformation. The purpose is that the second elastic member 25 can maintain the stability of its position, thereby continuously pressing the driving part 20 through the first linkage part 23, so that the driving handle does not rotate or rotates slightly, making the operation stability higher.

[0076] When the third elastic member 30 undergoes elastic deformation, the second locking body 29 rises. Continue to drive the first locking body 26 to move by operating the handle 18 until the indicating column 36 abuts against the limiting rod 34. At this time, the first locking body 26 and the second locking body 29 are just in a misaligned state, and the end of the movable cylinder 17 abuts against the end ring 27. Then, under the action of the gravity of the third elastic member 30 and the second locking body 29, the second locking body 29 moves downward until it locks the first locking body 26, completing the reset of the handle 18 and the movable cylinder 17. It is simple and convenient, just push the handle 18.

[0077] Moreover, during the downward movement of the second locking body 29, the support block 31 is located below or on the side of the second locking body 29. Therefore, the support block 31 does not affect the normal movement of the second locking body 29. However, when the second locking body 29 locks the first locking body 26, the support block 31 restricts the further downward movement of the second locking body 29 through the mating block 32; in this way, when unlocking the first locking body 26 and the second locking body 29 later, that is, when the first locking body 26 rotates downward, the second locking body 29 can be supported by the support block 31 and no longer move downward, so that the first locking body 26 can pass through the lower side of the second locking body 29 normally.

[0078] During use, the protective member 37 is located between the four fingers and the oven door 7, which can prevent the fingers from being rubbed or scalded, further improving the safety of use. Moreover, there is a gap between the protective member 37 and one end of the operating handle 18, so the protective member 37 does not affect the rotation of the operating handle 18. If it is not necessary to change the position of the operating handle 18, that is, if it is not necessary to extend the movable cylinder 17, then simply pull the operating handle 18 directly outwards; at this time, both ends of the operating handle 18 are respectively limited by the movable cylinder 17 and the protective body 38, so the acting force of the operating handle 18 can be better dispersed, and deformation at the connection between the operating handle 18 and the movable cylinder 17 is preferably prevented. At the same time, since the opening between the protective body 38 and the oven door 7 faces downwards, the protective body 38 does not affect the normal downward rotation of the operating handle 18. And during use, the heights of the positioning cylinders 16 on the two oven doors 7 are different, which can prevent mutual influence between the operating handles 18 on both sides.

[0079] It should be noted that the various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same or similar parts among the various embodiments, reference can be made to each other.

[0080] The above description is only a description of the preferred embodiments of the present invention, and does not limit the scope of the present invention in any way. Any changes and modifications made by those of ordinary skill in the technical field of the present invention based on the above disclosure are within the scope of protection of the claims.
