Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a portable electric lunch box. Background Technology

[0002] A lunchbox is a container used to store and carry food. It usually consists of a container body and a sealing lid, which are connected by a snap-fit. Many office workers now choose to bring their own lunches to save on living costs and also to be healthier. Since some places do not have heating facilities, there are also electric lunchboxes on the market.

[0003] Electric lunch boxes typically work by integrating heating elements into the base. These elements heat the bottom container, which in turn heats the food by adding water. The steam generated from the water in the bottom container heats the food in the top container. However, these electric lunch boxes heat up slowly, requiring a certain amount of time for the food to reach the desired temperature, which may not meet the needs of people with short lunch breaks. Utility Model Content

[0033] like Figure 1-5 As shown, a portable electric lunch box includes,

[0034] Box 10 has an inner cavity;

[0035] A partition 20 is disposed in the inner cavity and is adapted to divide the space inside the inner cavity into a water-filling cavity 101 and a receiving cavity 102. The water-filling cavity 101 is disposed above the receiving cavity 102 and has an opening.

[0036] The heating assembly 30 is disposed in the receiving cavity 102 and includes a heating plate 301 disposed at the bottom of the water-filled cavity 101 and a heating resistance wire 302 surrounding the side of the water-filled cavity 101.

[0037] A power supply assembly 40 is disposed within the receiving cavity 102 and located below the heating assembly 30; the power supply assembly 40 is electrically connected to the heating assembly 30.

[0038] A support plate 50 is installed in the opening. The support plate 50 has an air vent 501 that communicates with the water-holding cavity 101. A lunch box placement position is provided on the support plate 50.

[0039] The lunchbox body 60 includes a first body 601 disposed in the water-filling cavity 101 and a second body 602 disposed on the lunchbox placement position.

[0040] The cover 70 is placed on the box body 10. The cover 70 and the support plate 50 cooperate to form a heating chamber. The heating chamber is connected to the water chamber 101 through the air outlet 501. The cover 70 is provided with an air vent 701 that is connected to the heating chamber.

[0041] When using this utility model, the user pours water into the water-holding cavity 101, then places the first body 601 containing food into the water-holding cavity 101 through the opening, places the support plate 50 on the opening, and then places the second body 602 on the support plate 50. The cover 70 is then closed to maintain a seal. The heating component 30 operates, and the heating plate 301 and heating resistance wire 302 heat the water-holding cavity 101 from the bottom and sides, so as to quickly heat the water in the water-holding cavity 101, thereby heating the food in the first body 601. At the same time, the steam generated during the heating process will enter the heating chamber through the vent 501 to heat the second body 602 placed on the support plate 50, thereby achieving synchronous heating of the first body 601 and the second body 602.

[0042] This utility model uses a heating plate 301 and a heating resistance wire 302 to heat the water chamber 101 from the bottom and sides, thereby quickly heating the water in the water chamber 101 and then quickly heating the first body 601 and the second body 602, so that users can eat the heated food as soon as possible and reduce waiting time.

[0043] Furthermore, if the first body 601 is placed directly into the water-filled cavity 101, the bottom of the first body 601 will be in direct contact with the bottom of the water-filled cavity 101. During heating, the heat generated by the heating plate 301 will be directly conducted to the bottom of the first body 601 through the bottom of the water-filled cavity 101, causing the bottom temperature of the first body 601 to be too high, and the food at the bottom of the first body 601 to be directly burned. To avoid this problem, in this embodiment, multiple support seats 1011 are evenly installed at the bottom of the water-filled cavity 101. The bottom end of the first body 601 abuts against the top end of the support seat 1011, thereby separating the bottom of the first body 601 from the bottom of the water-filled cavity 101. During heating, the heat generated by the heating component 30 will be conducted to the first body 601 through water to heat the first body 601 evenly, while preventing the food in the first body 601 from burning due to excessive temperature.

[0044] Meanwhile, to facilitate the placement of the second body 602 and prevent it from shaking during operation, a limiting protrusion 502 is provided at the edge of the lunchbox placement position in this embodiment. The limiting protrusion 502 can limit the second body 602, thereby effectively preventing it from shaking during operation. In addition, to facilitate the heating of the second body 602 by the steam generated during the heating process, multiple air vents 501 are evenly provided at the lunchbox placement position in this embodiment, so that the steam generated during the heating process can be directly sprayed onto the surface of the second body 602 to heat the second body 602, thereby effectively improving the heating rate of the second body 602.

[0045] In addition, to facilitate the carrying of tableware, this embodiment also includes a tableware box 80 for placing tableware. The top of the cover 70 is provided with a receiving groove 702, and the tableware box 80 is disposed in the receiving groove 702 and is fixedly engaged with the receiving groove 702.

[0046] Meanwhile, to facilitate the carrying and use of the power supply assembly 40, in this embodiment, the power supply assembly 40 includes a power support 401 and a battery 402. The power support 401 is disposed in the receiving cavity 102, and the battery 402 is slidably mounted on the power support 401. The side of the box 10 is provided with an opening for the battery 402 to enter or leave the power support 401. The power support 401 is provided with electrical contacts that are electrically connected to the heating assembly 30. The battery 402 is electrically connected to the electrical contacts. The battery 402 is designed as a detachable structure, which allows users to quickly replace it when the lunchbox runs out of power without having to find a power outlet to charge it.

[0047] Furthermore, to prevent the cover 70 from separating from the box 10 during carrying, this embodiment also includes a locking assembly 90. The locking assembly 90 includes a protrusion 901 disposed on the upper edge of the box 10 and a fastening member 902 disposed on the lower edge of the cover 70. One end of the fastening member 902 is rotatably connected to the cover 70, and the other end is engaged with the protrusion 901 to connect the cover 70 and the box 10 as a whole.

[0048] In order to make it convenient for users to carry the electric lunch box, a handle 100 is also provided in this embodiment. The handle 100 is rotatably connected to the cover 70, so that users can carry the electric lunch box by pulling the handle 100.

[0049] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
