Description

Technical Field

[0001] This application relates to the field of tray technology, and in particular to a food tray. Background Technology

[0002] Food trays are common tools for holding food or plates and bowls. In public restaurants, food trays are mainly used to hold plates. However, when there are many diners, the restaurant will pre-load food onto plates so that diners can quickly purchase and eat. However, after a long period of operation, there will be leftover food on the plates. Subsequently, the food on the plates will slowly lose its calories, which will reduce the diners' dining experience. Utility Model Content

[0003] The purpose of this utility model is to provide a food tray in response to the defects and deficiencies of the existing technology.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The device includes a tray body, the upper surface of which has a holding groove, an insulated box below the tray body, the bottom of which is located inside the insulated box, the insulated box contains a heat-conducting liquid, a heating wire is horizontally placed inside the insulated box and is inserted into the heat-conducting liquid, and an insulated cover is placed on top of the tray body.

[0006] Preferably, one end of the heat-insulating cover is rotatably connected to one end of the tray body.

[0007] Preferably, a connecting plate is provided between one end of the heat-insulating cover and one end of the heat-insulating box, one end of the heat-insulating cover is rotatably connected to one end of the connecting plate, one end of the heat-insulating box is rotatably connected to the other end of the connecting plate, and the heat-insulating cover can be rotated to the bottom of the tray body.

[0008] Preferably, the inner bottom of the heat-insulating cover has a storage buckle, which can hold tableware.

[0009] Preferably, a sealing ring is provided between the tray body and the insulated box.

[0010] Preferably, the upper end of the heat preservation box is evenly provided with a plurality of locking buckles. One end of the locking buckle rotates the side wall of the heat preservation box, and a torsion spring is sleeved on the circumferential side of the rotation axis of the locking buckle. The torsion spring drives the other end of the locking buckle to be restricted to the upper end surface of the tray body.

[0011] Preferably, the side wall of the heat-insulating cover is embedded with transparent glass.

[0012] In summary, the beneficial technical effects of this application are as follows:

[0013] When placing food on a plate, place the plate into the holding slot of the tray body. Then, rotate the insulated cover to seal the top of the tray body. Turn on the switch to heat the heating wire to heat the heat-conducting liquid, raising the temperature inside the holding slot. This keeps the temperature between the tray body and the insulated cover high, ensuring the food inside the holding slot remains at a suitable temperature and maintaining a consistent dining experience.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] This application discloses a food tray.

[0020] Reference Figure 1 and Figure 2 The device includes a tray body 1, an insulated box 2 placed below the tray body 1, and an insulated lid 3 placed above the tray body 1. The upper surface of the tray body 1 has three holding slots 4, the lower ends of which protrude from the lower surface of the tray body 1. The upper periphery of the insulated box 2 has stepped grooves, within which the tray body 1 rests. Two connecting plates 5 are provided between one end of the insulated lid 3 and one end of the insulated box 2. One end of the insulated lid 3 is rotatably connected to one end of the connecting plate 5, and the other end of the connecting plate 5 is rotatably connected to one end of the insulated box 2. When it is time to eat, the insulated box 2 is lifted for easy food movement, and then the insulated lid 3 is rotated to be positioned below the insulated box 2, thereby increasing the height of the insulated box 2.

[0021] Reference Figure 3The insulated box 2 has an annular groove at the bottom of the stepped groove, and a sealing ring 6 is embedded in the annular groove. The upper end of the sealing ring 6 abuts against the lower end face of the tray body 1. Locking buckles 7 are rotatably connected to the corresponding sides of the upper end of the insulated box 2. The vertical cross-section of the locking buckle 7 is "L"-shaped, and the other end of the locking buckle 7 is engaged with the upper end face of the tray body 1. A torsion spring 8 is sleeved on the rotating shaft of the locking buckle 7. One end of the torsion spring 8 abuts against the locking buckle 7, and the other end abuts against the side wall of the insulated box 2. Under the action of the torsion spring 8, one end of the locking buckle 7 can be pressed tightly against the upper end of the tray body 1.

[0022] The inner bottom of the upper part of the heat preservation cover 3 has storage buckles 9 on both sides. The storage buckles 9 are composed of two limiting plates 10. The vertical cross section of the limiting plates 10 is "J" shaped. One end of the limiting plates 10 is integrally set in the inner bottom of the heat preservation cover 3. The two limiting plates 10 can clamp the tableware.

[0023] A transparent glass 11 is embedded and fixed in the upper side wall of the insulated lid 3. When food is located between the tray body 1 and the insulated lid 3, the internal situation can be observed through the transparent glass 11, making it convenient for diners to select food.

[0024] The heat-conducting liquid 12 is stored in the heat-conducting box 2. A heating wire 13 is wound and fixed inside the heat-conducting liquid 12. The heating wire 13 is located inside the heat-conducting liquid 12. A rotary switch 14 for controlling the operation of the heating wire 13 is installed on the outer wall of the heat-conducting box 2. Lifting grip grooves 15 are respectively opened at both ends of the heat-conducting box 2.

[0025] The implementation principle of a food tray disclosed in this application embodiment is as follows:

[0026] Place the plate into the holding slot 4 of the tray body 1, rotate the heat preservation cover 3 to seal the top of the tray body 1, and then turn on the switch to heat the heat-conducting liquid with the heating wire 13, so as to raise the temperature in the holding slot 4, thereby keeping the temperature between the tray body 1 and the heat preservation cover 3 at a high level, so that the food in the holding slot 4 is kept at a suitable temperature.

[0027] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
