Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments.

[0029] It should be understood that in the description of the present application, the orientation or positional relationship indicated by terms such as "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present application 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, and therefore cannot be understood as a limitation to the present application. The terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. That is, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In addition, unless otherwise specified, the meaning of "plurality" is two or more.

[0030] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0031] As Figures 1 - 3 shown, a food tray 100 that is easy to clean according to some embodiments of the present invention is used for detachably installing in a vacuum chamber 210 of a vacuum machine. The food tray 100 that is easy to clean includes a chassis 1 and a baffle 2 formed by bending the outer edge of the chassis 1 upward. The chassis 1 and the baffle 2 enclose a receiving space 3 for receiving food. The chassis 1 includes a recessed portion 11 that is recessed downward in the middle and an extension portion 12 that extends outward from the outer edge of the recessed portion 11. The extension portion 12 has two first bosses 13 that protrude upward. The first bosses 13 have first through holes 14. The upper end of the first through hole 14 communicates with the receiving space 3. The lower end of the first through hole 14 is configured to allow a conductive column 400 of the vacuum machine to pass through, so that the upper end of the conductive column 400 extends into the receiving space 3. Among them, the conductive column 400 is used to supply power to a heating rod 500.

[0032] When in use, a vacuum bag is placed on the chassis 1 of the food tray 100 that is easy to clean. During the process of the vacuum machine evacuating the vacuum bag, the leaked food gathers in the recessed portion 11. The position of the first bosses 13 is higher than that of the recessed portion 11, so that the conductive column 400 will not be soiled by food. After the vacuum operation on the vacuum bag is completed, the food tray 100 that is easy to clean can be detached from the vacuum chamber 210 of the vacuum machine, the food collected inside the food tray 100 that is easy to clean can be poured out, and the food tray 100 that is easy to clean can be cleaned.

[0033] Based on the above structural arrangement, the food tray 100 that is easy to clean is convenient to disassemble and clean, thereby keeping the inside of the vacuum machine clean.

[0034] As Figure 1 and 4 shown, in some embodiments, the extension portion 12 has a second boss 15 that protrudes upward. The second boss 15 has a second through hole 16. Or, as Figure 5 and 6 shown, in some embodiments, the baffle 2 has a second through hole 16. One end of the second through hole 16 communicates with the receiving space 3. The other end of the second through hole 16 is configured to communicate with a vacuum pump of the vacuum machine. In this way, the vacuum chamber 210 of the vacuum machine is evacuated through the second through hole 16 in the second boss 15, and further the receiving space 3 is in a vacuum state, so that a vacuum operation can be performed on the vacuum bag placed in the receiving space 3.

[0035] As Figure 1As shown, in some embodiments, the bottoms of the first boss 13 and the second boss 15 are both higher than the outer edge of the recess 11. In this way, the food leaked during the vacuuming process of the vacuum bag will flow into the recess 11 and will not enter the first through hole 14 in the first boss 13 and the second through hole 16 in the second boss 15, so that the vacuum chamber 210 of the vacuum machine will not be contaminated and the inside of the vacuum chamber 210 of the vacuum machine will be kept clean.

[0036] As Figure 1 shown, in some embodiments, the food tray 100 that is easy to clean includes a bag clip 5, and the bag clip 5 is installed on the inner wall of the edge 2. The bag clip 5 is used to fix the opening of the vacuum bag, prevent the vacuum bag from sliding, and at the same time keep the opening of the vacuum bag open and flat, so that the vacuuming of the vacuum bag is smooth, and the flat effect of the opening of the vacuum bag after heat sealing is ensured. Specifically, the bag clip 5 is installed in the groove formed on the inner wall of the edge 2 or is installed on the inner wall of the edge 2 through a support pillar.

[0037] As Figure 2 and 3 shown, in some embodiments, the food tray 100 that is easy to clean includes a temperature sensor 4, and the temperature sensor 4 is installed in the recess 11. In this way, the temperature of the food in the accommodation space 3 can be detected through the temperature sensor 4.

[0038] As Figure 2 and 3 shown, in some embodiments, the temperature sensor 4 includes a temperature sensing probe 41 and an electrode 42 electrically connected below the temperature sensing probe 41. The temperature sensing probe 41 is sealingly connected to the recess 11, and the electrode 42 passes downward through the recess 11 and enters the vacuum chamber 210 of the vacuum machine. Among them, the part where the electrode 42 passes through the recess 11 is sealed, and the temperature data obtained by the temperature sensor 4 is transmitted to the controller of the vacuum machine for analysis and processing.

[0039] In some embodiments, the food tray 100 that is easy to clean includes a weighing sensor disposed in the vacuum chamber 210, and the weighing sensor is installed on the bottom surface of the chassis 1. In this way, the weight of the food placed in the accommodation space 3 can be detected through the weighing sensor, and the weight data obtained by the weighing sensor is transmitted to the controller of the vacuum machine for analysis and processing.

[0040] As Figure 1 and 2 shown, in some embodiments, the inner side of the edge 2 is bent inward to form a flanging 21. The flanging 21 is beneficial to taking the entire food tray 100 that is easy to clean, so that it is convenient to install and disassemble the food tray 100 that is easy to clean in the vacuum chamber 210 of the vacuum machine.

[0041] In some embodiments, the chassis 1 and the flange 2 are integrally formed of metal or plastic. The integrally formed manner can reduce the manufacturing cost.

[0042] As Figure 4 shown, a food tray facilitating cleaning according to other embodiments of the present invention includes a chassis 200, a lid 300, two conductive posts 400, a heating rod 500, and a food tray 100 facilitating cleaning. The chassis 200 powers the heating rod 500 through the conductive posts 400. The vacuum bag can be evacuated in the vacuum chamber 210 of the chassis 200 and heat-sealed through the heating rod 500 to achieve the heat-sealed vacuum packaging operation of the vacuum bag. The leaked substances during this process are collected in the recess 11 of the food tray 100 facilitating cleaning, preventing them from flowing into the vacuum chamber 210.

[0043] The interior of the chassis 200 has a vacuum chamber 210. The lid 300 is installed on the chassis 200, and the lid 300 is used to open or close the vacuum chamber 210. The two conductive posts 400 are installed on the chassis 200, and the upper ends of the conductive posts 400 extend into the vacuum chamber 210. The heating rod 500 is disposed in the vacuum chamber 210. The food tray 100 facilitating cleaning is detachably installed in the vacuum chamber 210, and the upper ends of the conductive posts 400 pass through the first through hole 14 of the food tray 100 facilitating cleaning and are electrically connected to the heating rod 500.

[0044] When the vacuum machine completes the heat-sealed vacuum packaging of the vacuum bag, the lid 300 is opened to take out the food tray 100 facilitating cleaning for cleaning. At this time, the vacuum chamber 210 can remain clean.

[0045] Based on the above structural arrangement, by providing the food tray 100 facilitating cleaning that is convenient to disassemble and clean, the interior of the vacuum machine can be kept clean.

[0046] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
