It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0033] In the description of the present utility model, it should be noted that unless otherwise clearly defined and limited, the terms "installed", "connected", "connected to" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0034] In addition, the terms "horizontal", "vertical", "hanging", etc. do not mean that the components are required to be absolutely horizontal or hanging, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0035] As Figure 1 and Figure 2 shown, the present utility model provides a weighable cooking appliance, including: a box body 1, a cavity is formed inside the box body 1; a display panel is arranged outside the box body 1; an inner container 2, which is arranged in the cavity; an installation cavity is formed between the inner container 2 and the box body 1 (specifically, an installation cavity is formed between the outer wall of the inner container 2 and the inner wall of the box body 1); a tray support 3, which is located inside the inner container 2; a plurality of the tray supports 3 are arranged at intervals along the height direction of the inner container 2; the tray support 3 can place a tray; a weighing sensor 4, which is arranged in the installation cavity; on the width direction of the inner container 2, the weighing sensors 4 are connected to both sides of each of the tray supports 3; the weighing sensor 4 is communicatively connected to the display panel.

[0036] In this embodiment, a tray containing an object is placed on a tray support 3. After the tray is placed in place, the weighing sensors 4 on both sides of the tray support 3 can weigh the object on the tray and transmit the weighing structure to the display panel. The user can obtain the weight of the object on the tray from the display panel (it can be understood that the weighing result can be the average value measured by multiple weighing sensors 4). Each layer of the tray support 3 can hold a tray, and the weighing sensors 4 on both sides of each layer of the tray support 3 can weigh the tray on the corresponding tray support 3. Therefore, the weight-bearing cooking appliance provided in this embodiment can weigh the objects on multiple layers of trays simultaneously, which is convenient for the user to use. The weighing sensor 4 of the weight-bearing cooking appliance provided in this embodiment is arranged inside the cabinet 1, so it can be protected by the cabinet 1, avoiding damage caused by external impact, and making the service life of the weighing sensor 4 long. In addition, the weighing sensor 4 in the weight-bearing cooking appliance provided in this embodiment does not need to bear the self-weight of the entire machine, and the weighing object directly faces the tray and the object, reducing the range of the weight of the measured object, thereby improving the flexibility of the weighing sensor 4, and also improving the weighing accuracy. At the same time, the range of the weighing sensor 4 is reduced, the object weight is matched with the range of the weighing sensor 4, thereby reducing the cost of the weighing sensor 4, and also greatly reducing the ineffective bearing weight of the weighing sensor 4 in the idle state, and prolonging the life of the weighing sensor 4.

[0037] It can be understood that by using conventional technical means, the weighing result displayed on the display panel can not include the weight of the tray, that is, the result displayed on the display panel is the weight of the object.

[0038] Specifically, the weight-bearing cooking appliance further includes a door body. Openings are provided on the same side of the cabinet 1 and the inner liner 2, and the door body is connected to the cabinet 1 to be able to open and close the opening.

[0039] It can be set that the weight-bearing cooking appliance includes a controller. The weighing sensor 4 and the display panel are both communicatively connected to the controller. The weighing sensor 4 transmits information to the controller, and the controller transmits the weighing result to the display panel, and the display panel displays the weight of the object on the tray of the corresponding tray support 3.

[0040] As an alternative solution, as Figure 1 shown, the weighing sensors 4 on both sides of the tray support 3 are symmetrically arranged. Such an arrangement can improve the weighing accuracy. The two weighing sensors 4 symmetrically arranged on both sides of the tray support 3 are called symmetric weighing sensors 4. Along the depth direction of the inner liner 2, each load-bearing support can be provided with a symmetric weighing sensor 4, or multiple symmetric weighing sensors 4 can be provided, and the display panel displays the average value measured by multiple weighing sensors 4.

[0041] Based on the above embodiment, the weighing sensor 4 can be communicatively connected to the display panel through wireless communication.

[0042] As an alternative, as Figure 2 shown, the load cell 4 is communicatively connected to the display panel through a signal line 5, with low cost and reliable communication connection.

[0043] Based on the above embodiment, the structural form of the tray bracket 3 can be various. For example, the tray bracket 3 includes a support block protruding from the inner wall of the inner container 2, and the edge of the tray is lapped on the support block.

[0044] As an alternative, as Figure 1 and Figure 2 shown, the tray bracket 3 includes an upper limit member 31 and a lower support member 32 spaced apart along the height direction of the inner container 2; a slideway 33 is formed between the upper limit member 31 and the lower support member, and the tray can move along the slideway 33.

[0045] In this embodiment, the edge of the tray can move along the slideway 33 to the in-place position, the lower support member 32 supports the tray, and the upper limit member 31 can limit the tray. Such a setting can make the placement of the tray more stable.

[0046] Among them, along the depth direction of the inner container 2, a plurality of tray brackets 3 are spaced apart, that is, a plurality of tray brackets 3 perform multi-point support and limitation on the tray. It can be understood that during the process of inserting the tray, it is necessary to keep the position state of the tray aligned with the inlets of the plurality of slideways 33.

[0047] As an alternative, as Figure 2 shown, along the depth direction of the inner container 2, both the upper limit member 31 and the lower support member 32 extend from one side of the inner container 2 to the other side of the inner container 2. Thus, the slideway 33 is a continuous strip. In this way, as long as the tray is inserted into the slideway 33 from the inlet of the slideway 33, it can move along the slideway 33 to the in-place position, and there is no need to specifically maintain the position state of the tray, which is convenient for placing the tray.

[0048] Among them, both the upper limit member 31 and the lower support member 32 can be provided in a block shape.

[0049] Optionally, as Figure 2 shown, both the upper limit member 31 and the lower support member 32 are provided as U-shaped rods, with simple structure and small weight.

[0051] In this embodiment, the tray bracket 3 passes through the inner container 2 and is directly connected to the weighing sensor 4. Each tray bracket 3 is directly connected to the corresponding weighing sensor 4. When trays are placed on multiple tray brackets 3, the measurement of the weighing sensor 4 of one tray bracket 3 will not be affected by the trays on other tray brackets 3, further improving the weighing accuracy.

[0052] On the basis of the above embodiment, further, a seal is provided between the perforation and the tray bracket 3, thereby improving the sealing performance of the inner container 2. The seal can be an O-ring.

[0053] As Figure 1 and Figure 2 shown, on the basis of the above embodiment, further, the weighable cooking appliance further includes: a box body connecting frame 6, located in the installation cavity, and connected between one end of the box body 1 and the weighing sensor 4; a weighing connecting frame 7, located in the installation cavity, and connected between the tray bracket 3 and the other end of the weighing sensor 4.

The weighing sensor 4 generates a changing electrical signal due to the unequal forces on both sides, thereby realizing the measurement of the weights of the tray and the object.

[0055] The connection between the box body connecting frame 6 and the box body 1 and the weighing sensor 4 can be achieved by welding, clamping or by fasteners (such as bolts or screws, etc.). Similarly, the connection between the weighing connecting frame 7 and the tray bracket 3 and the weighing sensor 4 can be achieved by welding, clamping or by fasteners (such as bolts or screws, etc.).

[0056] Among them, the box body connecting frame 6 can be arranged in a straight shape. One end of the box body connecting frame 6 is fixedly connected to the box body 1, and the other end is fixedly connected to one end of the weighing sensor 4; the box body connecting frame 6 is arranged in a U shape. The back of the box body connecting frame 6 is fixedly connected to the box body 1, and one end of the weighing sensor 4 is inserted into the opening side of the box body connecting frame 6. Similarly, the weighing connecting frame 7 can be in a straight shape. One end of the weighing connecting frame 7 is fixedly connected to the tray bracket 3, and the other end is fixedly connected to the other end of the weighing sensor 4; or, the weighing connecting frame 7 is arranged in a U shape. The back of the weighing connecting frame 7 is fixedly connected to the tray bracket 3, and one end of the weighing sensor 4 is inserted into the opening side of the weighing connecting frame 7.

[0057] As an alternative solution, as Figure 2As shown, the box connecting frame 6 is arranged in a positive "L" shape, and the weighing connecting frame 7 is arranged in an inverted "L" shape; in the height direction of the inner tank 2, the box connecting frame 6 is connected to the bottom plate of the weighing sensor 4, and the weighing connecting frame 7 is connected to the top plate of the weighing sensor 4.

[0058] In this embodiment, the box connecting frame 6 is arranged in a positive "L" shape. Specifically, the box connecting frame 6 includes a first support plate and a second support plate that are perpendicularly arranged. The first support plate is fixedly connected to the box 1, and the second support plate is connected to the bottom plate of the weighing sensor 4; the weighing connecting frame 7 is arranged in an inverted "L" shape. Specifically, the weighing connecting frame 7 includes a third support plate and a fourth support plate that are perpendicularly arranged. The third support plate is fixedly connected to the tray support 3, and the fourth support plate is arranged on the top plate of the weighing sensor 4. The connection between the box connecting frame 6 and the weighing sensor 4 and the connection between the weighing connecting frame 7 and the weighing sensor 4 are arranged diagonally, and the force application point of the weighing sensor 4 is located on the top plate. In this way, the weighing sensor 4 is more sensitive to force strain, so that the measurement result is more accurate.
