The stove is placed on the cabinet, and the steam-bake oven is placed inside the cabinet. They are connected together through electrical connecting wires and control wires. The stove-steam-bake machine manufacturer only manufactures stoves and steam-bake ovens. The cabinet is kept by the user. After purchasing the stove-steam-bake machine, the user embeds the stove-steam-bake machine into the cabinet by himself or entrusts the seller to do so. However, the opening heights of cabinets in different users' homes are usually different, which results in different distances between the countertop on the cabinet used to overlap the stove and the bottom wall inside the cabinet. In order to facilitate the embedding of the stove-steam-bake machine into cabinets in different users' homes, it is necessary to provide a stove-steam-bake machine that allows the stove to overlap cabinets with different opening heights. Utility Model Content

[0003] Based on this, it is necessary to provide a stove-steaming and baking machine to address the above problems, which can allow the stove to be connected to cabinets with different opening heights.

[0004] In order to solve the above problems, the utility model provides the following technical solutions:

[0005] A stove-steaming and baking all-in-one machine, comprising:

[0006] A cooker, wherein the base of the cooker is a first base;

[0007] A steam oven is located below the cooker, and the base of the steam oven is the second base; and

[0008] A foot, detachably connected to the second base and at least partially located below the second base;

[0009] A limiting hole is provided on the first base, and a limiting guide is fixedly provided on the top side of the steam oven, the limiting guide comprises a guide rod and a limiting portion, the guide rod is vertically arranged and passes through the limiting hole, the first base moves up and down along the guide rod between the top side of the steam oven and the limiting portion, and the limiting portion is protruded on the side of the guide rod away from the steam oven to prevent the cooker from detaching from the guide rod.

[0011] The vertical dimension of the space on the limiting guide for the first base to move up and down is defined as D, and the thickness of the portion of the foot located below the second base is defined as T. When the stove-steam-bake machine is embedded in a cabinet, without installing foot pads, the height of the stove can be adjusted steplessly in the interval [0, D] by relying solely on the cooperation between the limiting guide and the limiting hole and the action of gravity. After installing the foot pads, the height of the stove can be adjusted steplessly in the interval [T, D+T]. Therefore, in the stove-steam-bake machine provided by the utility model, the height of the stove can be adjusted steplessly in the two intervals [0, D] and [T, D+T]. Therefore, the stove-steam-bake machine provided by the utility model enables the stove to be overlapped with cabinets with different opening heights.

[0012] In one embodiment, the vertical dimension of the space on the limiting guide for the first base to move up and down is D, the thickness of the portion of the foot located below the second base is T, and D=T.

[0013] With such a configuration, without installing the footrest, the height of the cooker can be adjusted steplessly in the range of [0, D], relying only on the cooperation between the limiting guide and the limiting hole and the action of gravity. After installing the footrest, the height of the cooker can be adjusted steplessly in the range of [T, D+T] (i.e., [D, 2D]). Therefore, the height of the cooker can be adjusted steplessly in the range of [0, 2D], which realizes stepless adjustment of the height of the cooker in a larger range.

[0014] In one of the embodiments, the stove-steam-bake combination machine further includes a rivet nut, which is fixed to the top side of the steam oven, and the limiting guide is a screw, which is threadedly connected to the rivet nut.

[0019] With such arrangement, the cooker can be moved relative to the steam oven along the length direction of the waist-shaped hole, thereby adjusting the position of the cooker in the front-rear direction.

[0020] In one embodiment, the foot is snap-connected to the second base.

[0021] Such arrangement facilitates the installation and removal of the footrest.

[0022] In one embodiment, the stepping foot includes a raising body, a connecting body and a locking buckle, the connecting body is fixedly arranged on the raising body, the locking buckle is convexly arranged on the connecting body and is spaced apart from the raising body to form a slot; a locking hole is provided on the second base, the locking hole includes a wider part and a narrower part, the stepping foot can be extended into the wider part of the locking hole to align the slot with the second base, and can be rotated after the slot is aligned with the second base to make the second base snap into the slot.

[0023] With such arrangement, when installing the foot, you only need to insert the foot into the lock hole to align the slot with the second base, and then rotate the foot to make the second base snap into the slot; when removing the foot, perform the opposite operation.

[0024] In one embodiment, the lock hole includes a circular hole and a strip hole, the strip hole is for the lock buckle to pass through, the circular hole is for the connector to extend into, and the strip hole is connected to the circular hole to form a wider part of the lock hole.

[0025] Such arrangement makes it easier to process the keyhole.

[0026] In one of the embodiments, two of the lock buckles and two of the strip-shaped holes are provided, the lock buckles and the strip-shaped holes are arranged in correspondence with each other, and the two strip-shaped holes are symmetrically arranged with respect to the circular hole.

[0027] Such an arrangement can improve the stability of the clamping connection between the foot and the second base.

[0049] See also Figures 1 to 3 The utility model provides a stove-steaming and baking machine, which comprises a stove 1, a steaming oven 2 and a foot 3. The base of the stove 1 is a first base 11, the steaming oven 2 is located below the stove 1, and the base of the steaming oven 2 is a second base. The foot 3 is detachably connected to the second base, and at least part of it is located below the second base.

[0050] See also Figure 4 and Figure 5 A limiting hole 111 is provided on the first base 11, and a limiting guide member 4 is fixedly provided on the top side of the steam oven 2. The limiting guide member 4 includes a guide rod 41 and a limiting portion 421. The guide rod 41 is vertically arranged and penetrates the limiting hole 111. The first base 11 moves up and down between the top side of the steam oven 2 and the limiting portion 421 along the guide rod 41. The limiting portion 421 is protruded on the side of the guide rod 41 away from the steam oven 2 to prevent the cooker 1 from being separated from the guide rod 41, thereby preventing the cooker 1 and the steam oven 2 from being too far apart and causing the electrical connection line and / or control line between the two to be disconnected.

[0051] The vertical dimension of the space on the limiting guide 4 for the first base 11 to move up and down is defined as D, and the thickness of the portion of the foot 3 located below the second base is defined as T. When the stove-steam-bake machine is embedded in a cabinet, without installing the foot 3, the height of the stove 1 can be adjusted steplessly in the interval [0, D] by relying solely on the cooperation between the limiting guide 4 and the limiting hole 111 and the action of gravity. After installing the foot 3, the height of the stove 1 can be adjusted steplessly in the interval [T, D+T]. Therefore, in the stove-steam-bake machine provided by the utility model, the height of the stove 1 can be adjusted steplessly in the two intervals [0, D] and [T, D+T]. Therefore, the stove-steam-bake machine provided by the utility model enables the stove 1 to be overlapped with cabinets with different opening heights.

[0052] Preferably, D=T. Without installing the foot 3, the height of the stove 1 can be adjusted steplessly in the interval [0, D] only by relying on the cooperation between the limiting guide 4 and the limiting hole 111 and the action of gravity. After installing the foot 3, the height of the stove 1 can be adjusted steplessly in the interval [T, D+T] (i.e., [D, 2D]). Therefore, the height of the stove 1 can be adjusted steplessly in the interval [0, 2D], which realizes the stepless adjustment of the height of the stove 1 in a larger interval.

[0053] Generally, the top side of the steam oven 2 is relatively thin, which makes the welding on the top side of the steam oven 2 easy to melt and the internal threading easy to slip. Therefore, it is not convenient to fix the limiting guide member 4 on the top side of the steam oven 2 by welding / self-tapping threading. Figure 4 In order to conveniently fix the limiting guide member 4 on the top side of the steam oven 2, the guide rod 41 is a rivet nut, the limiting guide member 4 includes a screw 42, the guide rod 41 is fixed on the top side of the steam oven 2, the screw 42 is threadedly connected to the rivet nut, and the screw head of the screw 42 forms a limiting portion 421. In other embodiments, the limiting guide member 4 can also be clamped on the top side of the steam oven 2.

[0054] See also Figure 4 In order to stably adjust the height of the cooker 1, a plurality of the limiting guide members 4 and the limiting holes 111 are provided, and each limiting hole 111 corresponds to one limiting guide member 4. Preferably, in order to simplify the structure of the cooker-steamer-bake machine, two limiting guide members 4 and two limiting holes 111 are provided. In other embodiments, the number of the limiting guide members 4 and the limiting holes 111 may be greater than two.

[0055] See also Figure 5 The limiting hole 111 is a waist-shaped hole, and the length direction of the waist-shaped hole is consistent with the front-back direction of the cooker 1. In this way, the cooker 1 can move relative to the steam oven 2 along the length direction of the waist-shaped hole, thereby adjusting the position of the cooker 1 in the front-back direction.

[0056] See also Figure 3 In some embodiments, the height of the bottom edge of the first base 11 is higher than the height of other parts of the bottom side of the first base 11. In these embodiments, in order to prevent the size of the limiting guide member 4 in the vertical direction from being too large, resulting in a low strength of the limiting guide member 4, the stove-steaming and baking machine further includes a bracket 5, which is fixedly mounted on the top side of the steaming oven 2 and is located directly below the edge of the first base 11, the first base 11 is overlapped on the bracket 5, and the limiting guide member 4 is fixed on the bracket 5. In these embodiments, the distance between the bottom side of the limiting portion 421 and the top side of the bracket 5 is D. In other embodiments, the first base 11 is directly overlapped on the top side of the steaming oven 2, and the distance between the bottom side of the limiting portion 421 and the top side of the steaming oven 2 is D.

[0057] In some embodiments, the foot 3 is snap-connected to the second base, which facilitates the assembly and disassembly of the foot 3 .

[0058] See also Figure 6 The foot pad 3 includes a heightening body 31, a connecting body 32 and a locking buckle 33. The connecting body 32 is fixed to the heightening body 31. The locking buckle 33 is convexly arranged on the connecting body 32 and is spaced apart from the heightening body 31 to form a locking groove 34. Figure 7 and Figure 8 The second base is provided with a locking hole 211, which includes a wider part and a narrower part. The foot 3 can be inserted into the wider part of the locking hole 211 to align the slot 34 with the second base, and can be rotated after the slot 34 is aligned with the second base to make the second base snap into the slot 34. When installing the foot 3, it is only necessary to first insert the foot 3 into the locking hole 211 to align the slot 34 with the second base, and then rotate the foot 3 to make the second base snap into the slot 34; when removing the foot 3, the opposite operation can be performed.

[0059] For example, the thickness of the heightening body 31 is 5 mm, and the distance between the bottom side of the limiting portion 421 and the top side of the bracket 5 is also 5 mm. In this way, without installing the foot 3, the height of the stove 1 can be adjusted steplessly in the range of [0, 5 mm] only by relying on the cooperation between the limiting guide 4 and the limiting hole 111 and the action of gravity. After installing the foot 3, the height of the stove 1 can be adjusted steplessly in the range of [5 mm, 10 mm]. In this way, the height of the stove 1 can be adjusted steplessly in the range of [0, 10 mm].

[0060] See also Figure 8 The lock hole 211 includes a circular hole 2111 and a strip hole 2112. The strip hole 2112 allows the lock buckle 33 to pass through, and the circular hole 2111 allows the connector 32 to extend into. The strip hole 2112 is connected to the circular hole 2111 to form a wider portion of the lock hole 211. In this way, it is easy to process the lock hole 211. In other embodiments, the lock hole 211 may also be elliptical, "X"-shaped, or irregularly shaped.

[0061] See also Figure 6 and Figure 8 There are two lock buckles 33 and two strip holes 2112, and the lock buckles 33 and the strip holes 2112 are arranged in a corresponding manner, and the two strip holes 2112 are symmetrically arranged about the circular hole 2111. This can improve the stability of the clamping between the foot 3 and the second base.

[0062] In other embodiments, the feet 3 may also be screwed to the second base. In these embodiments, the feet 3 may be completely located below the second base.

[0063] Preferably, see Figure 1, there are four feet 3, and the four feet 3 are respectively located at the four corners of the second base. In other embodiments, the number of the feet 3 can be 3, or more than 4. If the size of the feet 3 is large, the number of the feet 3 can also be 1 or 2.

[0064] In other embodiments, the positions of the limiting hole 111 and the limiting guide member 4 can be interchanged. In these embodiments, the limiting hole 111 is provided on the top side of the steam oven 2, and the limiting guide member 4 is fixedly provided on the first base 11. The limiting guide member 4 includes a guide rod 41 and a limiting portion 421. The guide rod 41 is vertically arranged and penetrates the limiting hole 111. The first base 11 moves up and down between the top side of the steam oven 2 and the limiting portion 421 along the guide rod 41. The limiting portion 421 is protruding on the side of the guide rod 41 away from the first base 11 to prevent the cooker 1 from being separated from the guide rod 41.

[0065] 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.

[0066] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
