The cover plate 20 is fixed to the base 10 by screws. A heating component 30 is provided in the middle of the cover plate 20 and slides with the guide structure under the action of gravity. The heating component 30 is formed with an arc-shaped convex surface that matches the bottom surface of the dish. Several gripping arms 50 are provided on the edge of the base 10, one end of which contacts the heating component 30 and rises and holds the dish when the heating component 30 slides down under the action of gravity. The gripping arms 50 can hold the dish tightly, avoid collision, and prevent the dish from tipping over. It is highly practical and can also avoid the problem of splashing of heated vegetable juice to stain clothes or scalding.

[0028] The base 10 is also provided with an electric control component 40 for controlling the heating component 30, and the electric control component 40 includes a control circuit board 401, an adjustment knob 402 connected to the control circuit board 401, and an AC power plug 403 and an AC line 404 connected to the control circuit board 401 and used to connect an external power source and another warm vegetable tray.

In this embodiment, each warm vegetable tray is provided with an AC line 404 that can be connected to the AC power plug 403 of another warm vegetable tray, and one of them is connected to the external power source. A power source is enough, and multiple vegetable warmers can be connected in parallel, up to 16 dishes can be connected in parallel, and the temperature can be controlled individually by the adjustment knob 402 on each vegetable warmer; an arc-shaped receiving groove for accommodating an AC power plug 403 is provided on the bottom surface of the base 10, and the heating temperature of the heating component 30 can be controlled by adjusting the knob 402, and the arc-shaped receiving groove is used to collect the AC power plug 403; in order to improve the safety of the vegetable warmer, a negative temperature coefficient thermistor is provided on the control circuit board, and the temperature can be effectively controlled by the negative temperature coefficient thermistor to realize automatic temperature adjustment, which is safe and reliable.

[0029] It can be seen that the vegetable warming tray of the present embodiment can improve the heating efficiency and effectively reduce energy consumption by forming an arc-shaped convex surface that matches the bottom surface of the vegetable plate on the heating component 30 and increasing the contact area between the heating component 30 and the bottom of the vegetable plate. By arranging a plurality of gripping arms 50 on the edge of the base 10, when the heating component 30 is affected by the gravity of the vegetable plate, the heating component 30 moves downward along the guide structure, so that the heating component 30 pushes the gripping arms 50 to tilt back and hold the vegetable plate tightly, thereby preventing the vegetable plate from tipping over.

[0030] In this embodiment, four columns with threaded holes are provided inside the base 10 , and the control circuit board 401 is fixed to the columns by screws, so that the control circuit board 401 is suspended inside the base 10 .

[0031] In this embodiment, the base 10 is provided with a lug 101 having the same number as the gripping arm 50, each lug 101 is provided with a hanging plate 102, and the lugs 101 at both ends of the hanging plate 102 are provided with a receiving cavity 103, and the lugs 101 are provided to facilitate the carrying of the warming dish tray; see Figure 4 The cover plate 20 is provided with a cover ear 201 corresponding to the lug 101, each cover ear 201 is provided with a movable opening for the grab arm 50 to move, the bottom surface of one side of the movable opening is an inclined surface 202, the inclined surface 202 is in contact with the end surface of the grab arm 50, and the cover ears 201 at both ends of the movable opening are provided with limiting grooves 203 corresponding to the accommodating cavity 103, the cover ear 201 and the lug 101 are fixed by screws, and the grab arm 50 is fixed to the base 10 by the cooperation of the cover ear 201 and the lug 101;

[0032] For further information, see Figure 3The cover ear 201 and the lug 101 are provided above, and a mounting shaft 501 is formed at the bottom of the grab arm 50, and the grab arm 50 grows out of both ends of the mounting shaft 501. A torsion spring 502 is installed on the mounting shaft 501 to allow the grab arm 50 to be suspended on the suspension plate 102. When the cover plate 20 is covered with the base 10, both ends of the mounting shaft 501 are wrapped by the accommodating cavity 103 and the limiting groove 203, so that the mounting shaft 501 can rotate. The grab arm 50 includes a first step contact end 503 and a second step contact end 504, and a second step contact end 504 away from one end of the first step contact end 503. The step contact end 504 has a buckle portion 505, and the upper end surface of the first step contact end 503 contacts the heating component 30, and the connection between the first step contact end 503 and the second step contact end 504 is formed with an arc surface that cooperates with the inclined surface 202. Through this arrangement, when the heating component 30 is affected by the gravity of the dish, the heating component 30 moves downward along the guide structure, so that the heating component 30 pushes the grasping arm 50 to tilt back, so that the second step contact end 504 holds the dish tightly, and the buckle portion 505 buckles the dish, which can prevent the dish from tipping over.

[0033] It should be noted that the position of the buckle 505 is slightly higher than the height of the dish, so that when the dish is picked up, the grab arm 50 spreads outward due to the lack of gravity of the heating component 30, and the dish will not be blocked by the buckle 505 and cannot be picked up; or, the position height of the buckle 505 is consistent with the height of the dish. When the dish needs to be picked up, the buckle 505 is pushed open to separate the buckle 505 from the dish.

[0034] In this embodiment, the guide structure includes a plurality of guide posts 204 arranged on the cover plate 20 and a socket 104 arranged in the base 10 and corresponding to the guide posts 204. The socket 104 has a guide hole, and the bottom end of the guide post 204 is inserted into the guide hole. Limiting plates 105 are formed on both sides of the socket 104. The guide post 204 is sleeved with a reset spring 106 with one end abutting against the limiting plate 105 and the other end abutting against the heating component 30. After picking up the dish, since the heating component 30 is without the action of gravity, the heating component 30 is pushed to reset by the reset spring 106, and the grab arm 50 follows the heating component 30 to rise along the guide post 204 and spreads out, so as to facilitate taking out the dish.

[0035] Further, in this embodiment, please refer to Figure 5The heating component 30 includes a movable bracket 301, a heating element 302 and a heat conducting plate 303. The movable bracket 301 and the heating element 302 are disc-shaped. The heating element 302 is installed in the movable bracket 301. The heat conducting plate 303 is arranged between the heating element 302 and the movable bracket 301, and the heat conducting plate 303 is clamped by the heating element 302 and the movable bracket 301. The heating element 302 adopts a heating wire or a heating film; the heat conducting plate 303 is made of a silicone material, and the heat conducting plate 303 is arranged in an arc shape, so that the surface of the heat conducting plate 303 forms an arc that matches the bottom of the dish. shaped raised surface, the edge of the movable bracket 301 is provided with a vertical rod 304 corresponding to the guide column 204, the vertical rod 304 is provided with a guide slide hole through which the guide column 204 passes, and the bottom of the vertical rod 304 abuts against the reset spring 106. Through this arrangement, the heating component 30 can move down along the guide column 204 under the action of gravity, and drive the grab arm 50 abutting against the movable bracket 301 to tilt back. In the absence of gravity, the heating component 30 can be pushed by the reset spring 106 to move up along the guide column 204, and the grab arm 50 gradually disperses as the heating component 30 rises.

[0036] Specifically, in order to further prevent the dish placed on the dish warmer from moving, anti-skid stripes 205 are provided on the upper surface of the cover plate 20. The anti-skid stripes 205 further prevent the dish from tipping over when it is hit.

[0037] Furthermore, the table top of a dining table is generally smooth. In order to prevent the warm dish tray from sliding on the table top and falling over when the dining table is bumped, a plurality of grooves are formed at the bottom of the base 10. The grooves are evenly distributed on the base 10. Anti-slip pads are installed in the grooves. The thickness of the anti-slip pads is greater than the depth of the grooves, so that the anti-slip pads protrude from the grooves to play an anti-slip role.

[0038] 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.
