Description

Technical Field

[0001] The utility model relates to the field of cooking devices, and particularly relates to a steam oven with an automatically ejected steam baking tray. Background Art

[0002] Most of the steam ovens currently on the market are designed in the traditional mode, that is, users need to manually place the steam baking tray into the steam oven, and then place the dishes on the steam baking tray. After cooking is completed, the user's hand needs to reach into the steam oven to take the dishes on the steam baking tray. However, under the existing technical framework, the internal cavity space of the steam oven is designed to be relatively compact, which limits the range of hand movement in the steam oven. During use, users not only need to bend down and lower their heads to put the dishes into the narrow internal cavity, but also after cooking, the high-temperature internal cavity environment increases the difficulty for users to take the food, and there is a high risk of scalding.

[0003] In response to this, the Chinese utility model patent "An Oven with Automatically Ejected Baking Tray" with the application number 201921536959.1 (the authorized announcement number is CN 211355061 U) proposed an improved structure. In this patent, when the left and right lead screws drive the left and right sliding rods to slide back and forth respectively, they can simultaneously drive the left and right first connecting rods to move obliquely downward along the left and right guide rails. At this time, the reaction forces exerted by the left and right first connecting rods on the left and right sliding columns are decomposed into the downward sliding forces of the left and right sliding columns along the left and right vertical sliding rails and the forward sliding forces of the left and right sliders along the left and right horizontal sliding rails, so that the left and right side brackets can slide outward along the left and right horizontal sliding rails and be pushed out from the inner cavity, thereby facilitating the user to take the baking tray and effectively avoiding the risk of the user being scalded when reaching into the inner cavity to take the baking tray. However, although the design disclosed in this patent improves the use experience to a certain extent, its complex mechanical structure brings new challenges. Too many connecting parts and transmission parts not only increase the possibility of failures, but also make the assembly process cumbersome, thus affecting the stability of the product and the actual experience of users. Therefore, in view of the limitations of the existing technology, further in-depth research and improvement are still needed. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a steam oven with an automatically ejected steam baking tray and fewer connecting parts and transmission parts in view of the above technical status.

[0005] The technical solution adopted by the utility model to solve the above technical problem is as follows: A steam oven with an automatically ejected steam baking tray, comprising

[0006] a box body, with an opening at the front side and connected with a box door, and the left and right inner side walls of the box door are respectively provided with steam baking tray guide rails extending in the front-back direction;

[0007] a steam baking tray, the left and right sides of which are respectively arranged in the corresponding steam baking tray guide rails, and the steam baking tray can slide back and forth along the steam baking tray guide rails;

[0008] It is characterized in that it further includes

[0009] A linear motion motor, installed on the inner upper wall of the box body, and its linear track extends in the front-rear direction;

[0010] A transmission frame, arranged at the rear side of the steaming baking tray, includes a cross bar extending in the left-right direction. The cross bar is driven by the linear motion motor and moves along the linear track of the linear motion motor. Vertical rods extend downward from both ends of the cross bar, and the vertical rods can act on the rear side of the steaming baking tray and push the steaming baking tray forward.

[0011] In order to enable the steam oven to have the function of automatically pulling back the steaming baking tray at the same time, further, the steaming baking tray has a rim protruding upward from the tray surface. The vertical rod extends with a pull rod part. The pull rod part has a pull rod cross section extending from the outside of the rim of the steaming baking tray to the inside of the rim. After the pull rod cross section extends to the inside of the rim, it turns downward to extend a pull rod vertical section. The linear motion motor drives the transmission frame to move back and forth through forward rotation and reverse rotation. When the transmission frame moves backward, the pull rod vertical section of the transmission frame can pull back the steaming baking tray, so that the steaming baking tray returns to the box body along the steaming baking tray guide rail.

[0012] Preferably, the vertical rod further extends with a push rod part. The push rod part has a push rod cross section extending in the direction of the other vertical rod. The end of the push rod cross section extends downward with a push rod vertical section. The push rod vertical section is located outside the rim of the steaming baking tray. The push rod vertical section of the vertical rod plays a role in assisting in pushing the steaming baking tray, and together with the main body part of the vertical rod, it realizes the automatic pushing function of the steaming baking tray, making the pushing of the steaming baking tray more stable.

[0013] Specifically, the pull rod cross section extends from the end of the push rod cross section of the push rod part to the inside of the rim of the steaming baking tray.

[0014] Preferably, the push rod vertical section and the pull rod vertical section are respectively located outside and inside the rim of the steaming baking tray, and are arranged close to the rim of the steaming baking tray. When the steaming baking tray is pushed out, the contact surface between the steaming baking tray and the steaming baking tray guide rail decreases, and the steaming baking tray may become unstable. The push rod vertical section and the pull rod vertical section can play a role in fixing the steaming baking tray to prevent the steaming baking tray from tilting forward.

[0015] Further, there are at least two steaming baking trays, and each vertical rod has a pull rod part corresponding to the number of steaming baking trays and a push rod part corresponding to the number.

[0016] In order to reduce the occupation of the internal space of the box body, preferably, the left and right inner side walls of the box body are recessed to form the steaming baking tray guide rail extending in the front-rear direction.

[0017] Preferably, a control panel is provided outside the box body. The control panel is signal - connected to the linear motion motor and can control the linear motion motor to drive the steaming baking tray to be pushed out of or into the box body. Users can operate the automatic pushing out and pulling in of the steaming baking tray through the "Push / Pull Steaming Baking Tray" button on the control panel.

[0018] Furthermore, the box body is also provided with a vibration control module. The vibration control module is signal - connected to the linear motion motor and can control the linear motion motor to drive the steaming baking tray to be pushed out of or into the box body. This structure provides another optional solution for users, that is, users can directly complete the control of the steam oven by knocking a specified number of times.

[0019] The utility model precisely drives the transmission rack by the linear motion motor installed on the upper inner wall of the box body. Then, through the double vertical rods of the transmission rack, the steaming baking tray is steadily pushed forward, realizing the automatic pushing out of the steaming baking tray. Compared with the prior art, the utility model significantly simplifies the connection and transmission structure, reduces the possibility of failure, simplifies the assembly process at the same time, and improves the production efficiency. The automatic extension of the steaming baking tray not only eliminates the risk of scalding during operation in the high - temperature inner cavity but also allows users to comprehensively observe the state of the dishes to ensure the cooking effect. If it is found that the dishes are not cooked, the steaming baking tray can be safely retracted at any time to continue cooking. Description of the Drawings

[0026] The following further describes the present utility model in detail with reference to the embodiments of the drawings.

[0027] As Figures 1 to 6As shown in the figure, it is a preferred embodiment of a steam oven with an automatically ejected steam baking tray according to the present utility model. The steam oven includes a box body 1 with a steam baking tray 3 inside, and realizes the automatic ejection and retraction functions of the steam baking tray 3 through the drive of a linear motion motor 6 and the transmission of a transmission frame 5.

[0028] Refer to Figure 1 and Figure 2 , the front side of the box body 1 of the steam oven is open and connected with a box door 2. When the box door 2 is closed, a closed inner cavity space can be formed between the box door 2 and the box body 1. The left and right inner side walls of the box body 1 are respectively provided with steam baking tray guide rails 11 extending in the front-back direction. In this embodiment, the steam baking tray guide rails 11 are directly recessed from the left and right inner side walls of the box body 1, so as to avoid occupying the inner cavity space caused by the additional installation of the steam baking tray guide rails 11. The front view and side view of the steam baking tray guide rails 11 can refer to Figure 3 and Figure 4 .

[0029] The number of the steam baking trays 3 can be designed according to actual needs. In this embodiment, two steam baking trays 3 are arranged in parallel up and down in the box body 1. The left and right sides of the steam baking trays 3 are respectively arranged in the corresponding steam baking tray guide rails 11, and the steam baking trays 3 can slide back and forth along the steam baking tray guide rails 11. The steam baking tray 3 has a rim 31 protruding upward from the tray surface. The rim 31 is annularly surrounded by the outermost periphery of the tray body. The rim 31 can not only prevent the dishes placed on the tray surface from slipping off the steam baking tray 3, but also is the main force-bearing part for the steam baking tray 3 to realize automatic ejection and retraction.

[0030] The linear motion motor 6 is a driving device for the steam oven to realize the automatic ejection and retraction of the steam baking tray 3. It is fixedly installed on the inner upper wall of the box body 1 through a bolt structure. Its linear track 61 extends in the front-back direction. Through the transmission of the transmission frame 5, the steam baking tray 3 can be driven to be ejected and retracted into the box body 1 along the extension direction of the linear track 61.

[0031] The transmission frame 5 includes a cross bar 51 extending in the left-right direction. Vertical bars 52 extend downward from both ends of the cross bar 51, making the whole transmission frame 5 in a gantry shape. The cross bar 51 of the transmission frame 5 is driven by the linear motion motor 6 installed on the inner upper wall of the box body 1 to move back and forth along the linear track 61 of the linear motion motor 6. The vertical bars 52 of the transmission frame 5 abut against the rear side of the rim 31 of the steam baking tray 3. When the transmission frame 5 moves forward, the vertical bars 52 of the transmission frame 5 exert a force on the steam baking tray 3 to drive the steam baking tray 3, so that it is ejected from the box body 1.

[0032] See Figure 5 and Figure 6, the vertical rod 52 of the transmission frame 5 also extends a push rod portion 53 and a pull rod portion 54. The push rod portion 53 of the vertical rod 52 has a push rod horizontal section 531 extending in the direction of the other vertical rod 52. The end of the push rod horizontal section 531 extends downward to form a push rod vertical section 532. The push rod vertical section 532 of the vertical rod 52 is located outside the rim 31 of the steaming baking tray 3, that is, the rear side of the steaming baking tray 3. The push rod vertical section 532 of the vertical rod 52 plays a role in assisting the pushing of the steaming baking tray 3, and together with the main body portion of the vertical rod 52, it realizes the automatic pushing function of the steaming baking tray 3, making the pushing of the steaming baking tray 3 more stable.

[0033] The pull rod portion 54 has a pull rod horizontal section 541 extending from the outside of the rim 31 of the steaming baking tray 3 to the inside of the rim 31. After the pull rod horizontal section 541 extends to the inside of the rim 31, it turns downward to extend a pull rod vertical section 542. In this embodiment, the pull rod horizontal section 541 of the pull rod portion 54 extends from the end of the push rod horizontal section 531 of the push rod portion to the inside of the rim 31 of the steaming baking tray 3. The pull rod portion 54 and the push rod portion 53 together form a claw-shaped pushing and pulling action portion. The linear motion motor 6 drives the transmission frame 5 to move forward and backward through forward rotation and reverse rotation. When the transmission frame 5 moves backward, the pull rod vertical section 542 of the transmission frame 5 can pull the steaming baking tray 3 back, so that the steaming baking tray 3 returns to the box body 1 along the steaming baking tray guide rail 11.

[0034] Each vertical rod 52 has two sets of push rod portions 53 and pull rod portions 54 corresponding to the number of steaming baking trays 3. The upper set of push rod portion 53 and pull rod portion 54 on the vertical rod 52 are used to push and pull the upper steaming baking tray 3, and the lower set of push rod portion 53 and pull rod portion 54 are used to push and pull the lower steaming baking tray 3. In this embodiment, the main body part of the vertical rod 52 at the end for pushing the lower steaming baking tray 3 is cancelled on the vertical rod 52 of the transmission frame 5, and only the push rod vertical section 532 is relied on to achieve the pushing effect. This makes the overall transmission frame 5 more beautiful without affecting its function.

[0035] The push rod vertical section 532 and the pull rod vertical section 542 are respectively located outside and inside the rim 31 of the steaming baking tray, and are arranged close to the rim 31 of the steaming baking tray 3. When the steaming baking tray 3 is pushed out, the contact surface between the steaming baking tray 3 and the steaming baking tray guide rail 11 decreases, and the steaming baking tray 3 may become unstable. The push rod vertical section 532 and the pull rod vertical section 542 can play a role in fixing the steaming baking tray 3 to prevent the steaming baking tray 3 from tilting forward, as Figure 1 shown.

[0036] In this embodiment, a control panel 4 is provided outside the box body 1. The control panel 4 is signal-connected to the linear motion motor 6 and can control the linear motion motor 6 to drive the steaming baking tray 3 to be pushed out or enter the box body 1. The user can control the automatic pushing out and pulling in of the steaming baking tray 3 through the "Push out / Pull in Steaming Baking Tray" button on the control panel 4. In addition, a vibration control module (not shown in the figure) is installed on the left side of the control panel 4. The vibration control module is signal-connected to the linear motion motor 6, and the steaming baking tray 3 can be pushed out / pulled in by knocking twice.

[0037] When the user uses this embodiment, first hold the steaming baking tray 3 by hand and align it with the pull rod part 54 and the push rod part 53 of the transmission frame 5 on both sides of the steaming baking tray track, and place the steaming baking tray 3 into the steaming baking tray track. The inner disk edge 31 of the steaming baking tray 3 is clamped between the pull rod part 54 and the push rod part 53, and then the steaming baking tray 3 is sent into the cavity by operating the control panel 4 or the vibration control module. Similarly, after cooking is completed, the steaming baking tray 3 is pushed out by operating the control panel 4 or the vibration control module.

[0038] The utility model uses the linear motion motor 6 installed on the inner upper wall of the box body 1 to accurately drive the transmission frame 5, and then steadily pushes the steaming baking tray 3 forward through the double vertical rods 52 of the transmission frame 5, realizing the automatic pushing out of the steaming baking tray 3. Compared with the prior art, the utility model significantly simplifies the connection and transmission structure, reduces the possibility of failure, simplifies the assembly process, and improves the production efficiency. The automatic extension of the steaming baking tray 3 not only eliminates the risk of scalding during operation in the high-temperature box body 1, but also allows the user to comprehensively observe the state of the dishes to ensure the cooking effect. If it is found that the dishes are not cooked, the steaming baking tray 3 can be safely retracted at any time and continue cooking.
