Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected" and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1, an embodiment of the present invention provides an electric steam box, which at least includes: a water storage tank 1, which is penetrated with a water outlet 11 along the thickness direction; the connecting groove 2 is arranged on the bottom surface of the water storage tank 1 and is communicated with the water outlet 11; the evaporation chamber 3 is communicated with the connecting groove 2; and the float switch 4 is movably arranged in the connecting groove 2 and is abutted to or separated from the water outlet 11.

It should be noted that the water yield of the water outlet 11 should be greater than or equal to the water yield flowing into the evaporation chamber 3 from the connecting groove 2, so that the electric steaming box will not be dry-burned due to the evaporation yield being greater than the water yield. The sum of the dead weight of the float switch 4 and the static pressure of the water borne by the float switch when the water storage tank 1 is at the highest water level is less than or equal to the buoyancy borne by the float switch 4, so that the water outlet of the water storage tank can be still sealed by the float switch when the water storage tank is at the highest water level.

The working principle is as follows: the opening and closing of the water outlet 11 of the water storage tank 1 are controlled by the float switch 4 to supply water or stop supplying water. When the water level in the evaporation chamber 3 is low, the water level of the connection groove 2 communicated therewith is also low, so that the float switch 4 is separated from the water outlet 11, so that the water in the water storage tank 1 can flow into the connection groove 2 and then into the evaporation chamber 3, so that the water level in the evaporation chamber 3 rises. When the water level in the evaporation chamber 3 is higher than the bottom surface of the connecting groove 2, the float switch 4 is driven to rise together until the float switch 4 seals the water outlet 11 of the water storage tank 1, and at the moment, the water storage tank 1 stops supplying water to the evaporation chamber 3. When the temperature in the evaporation chamber 3 rises and water becomes steam, the water level in the evaporation chamber 3 falls, so that the water level of the connecting groove 2 also falls, the float switch 4 falls and is separated from the water outlet 11, the water outlet 11 is opened, and the water storage tank 1 continues to supply water into the evaporation chamber 3 through the connecting groove 2.

It will be appreciated that the float switch 4 movably disposed within the connecting groove 2 is brought into abutment with or separated from the water outlet 11 so that the water outlet 11 is closed or opened to stop or start the supply of water, i.e., the water storage tank 1 supplies or stops the supply of water to the evaporation chamber 3 through the connecting groove 2. The water storage tank 1 can be controlled to supply water to the evaporation chamber 3 or stop supplying water only by moving the float switch 4 in the connecting groove 2 to realize separation and abutting with the water outlet 11, and components such as an inductor, a water pump and the like are not required to be additionally arranged, so that the integral structure is greatly simplified, the use of circuit components is reduced, and the functional stability of the electric steam box is improved; and meanwhile, after a water pump part is omitted, the electric steam box cannot generate overlarge noise.

In one embodiment, as shown in fig. 2, a water inlet 21 is formed through the side wall of the connecting groove 2, so that the evaporation chamber 3 is communicated with the connecting groove 2, and water flowing out of the water outlet 11 flows into the water inlet 21 through the connecting groove 2 and then flows into the evaporation chamber 3 through the water inlet 21.

In another embodiment, as shown in fig. 4, the electric steaming box further comprises a water pipe 8, and a switch 9 disposed on the water pipe. One end of the water pipe 8 is communicated with the connecting groove 2, and the other end is communicated with the evaporation chamber 3. It will be appreciated that the length of the water tube 8 may be adjusted as required. The water from the water outlet 11 flows into the water pipe 8 through the connecting groove 2 and then flows into the evaporation chamber 3 through the water pipe 8. Switch 9 on the water pipe 8 can be controlled by the rivers that the spread groove 2 flowed into in the evaporating chamber 3, through water pipe 8 and switch 9 combined action, can effectively control the flow that the spread groove 2 flowed into the evaporating chamber 3. The switch 9 can also control heating at the same time to prevent dry heating caused by no water flowing into the evaporation chamber. When the switch 9 is turned on, water flow and heating are synchronously started, and water flows into the evaporation chamber at the moment, so that the condition of dry burning is avoided.

The height of the bottom surface of the connecting groove 2 is greater than or equal to the height of the bottom surface of the evaporation chamber 3. In a preferred embodiment, the bottom surface of the connecting groove 2 is higher than the bottom surface of the evaporation chamber 3. At this time, the water flows into the evaporation chamber 3 from the connecting groove 2 more smoothly under the action of gravitational potential energy, and the water level in the evaporation chamber 3 always has a certain height (because of the height difference from the bottom surface of the connecting groove 2 to the bottom surface of the evaporation chamber 3), thereby effectively avoiding the dry burning phenomenon caused by insufficient water supply.

In one embodiment, as shown in fig. 2, in the present embodiment, a plurality of protrusions 22, which may have any shape, are formed on the inner upper and lower surfaces of the connecting groove 2. Set up protruding 22, can reduce the area of contact of float switch 4 and the inside upper surface or the lower surface of spread groove 2, can effectively avoid float switch 4 to go up to float the decline in-process because of moisture adsorbs at the inside upper surface or the lower surface of spread groove 2, avoids float switch 4 in spread groove 2 untimely condition of motion, ensures that aqua storage tank 1 in time supplies water or does not supply water to evaporating chamber 3. In other embodiments, the difference from the previous embodiment is that a plurality of protrusions 22 are formed on one of the upper and lower surfaces inside the coupling groove 2.

As shown in fig. 3, the connecting groove 2 is formed with a vent hole 23 communicating with the outside. Exhaust hole 23 is located water inlet 21 top, and exhaust hole 23 is vertical setting, makes the external atmospheric pressure of spread groove 2 intercommunication through exhaust hole 23, and is unanimous with the external world with the pressure in the spread groove 2, prevents that the too high condition that makes float switch 4 normal direction come-up of pressure in the spread groove 2 from appearing, and float switch 4 can not in time butt delivery port 11 promptly, seals delivery port 11. In other embodiments, as shown in fig. 2, the vent hole 23 may be arranged in other forms, the vent hole 23 is arranged horizontally, one end of the vent hole 23 is communicated with the connecting groove 2, and the other end is communicated with the outside.

In one embodiment, as shown in fig. 1 and 3, the electric steaming box further includes a first cover 51 and a second cover 52 integrally or separately connected to the first cover 51. The first cover 51 is disposed to cover the evaporation chamber 3, and the second cover 52 is disposed to cover the water storage tank 1. Wherein, a plurality of air outlet holes 511 are formed on the first cover body 51, and each air outlet hole 511 is communicated with the evaporation chamber 3; the first cover 51 is used to cover the evaporation chamber 3. The second cover 52 is used to seal the water outlet tank. The cross section of each air outlet 511 is rectangular, and the shape of the air outlet 511 can be adjusted according to the needs. The air outlet 511 is arranged, after the steam generated by the evaporation chamber 3 contacts with food, the condensed water drops of the steam and food residues are accumulated on the cover body and cannot flow into the steam chamber, and the workload generated by cleaning the steam chamber is reduced.

Specifically, in the present embodiment, the first cover 51 and the second cover 52 are integrally formed, so that the overall structure of the first cover 51 and the second cover 52 is more stable, and the processing and forming are convenient. In other embodiments, the fastening may be by bolts or the like.

As shown in fig. 1 and 3, the electric steaming box further includes a heat generating member 6 mounted at a lower portion of the evaporation chamber 3, and a sealing member 7 disposed between the heat generating member 6 and the evaporation chamber 3. It is understood that the heat generating member 6 may be in the shape of a disk for heating the water in the evaporation chamber 3 to change the water in the evaporation chamber 3 into steam. The aqua storage tank 1 is separated from the evaporation chamber 3 and is arranged, the heating part 6 only needs to heat the evaporation chamber 3, the whole aqua storage tank is not required to be heated, and therefore, a small heating part can be used, the steam generation rate is improved, and the energy is saved. Sealing member 7 can be the sealing washer, adopts sealing member 7 can separate the piece that generates heat with evaporating chamber 3 effectively, prevents the moisture infiltration, also prevents that evaporating chamber 3 from heating the back for a long time and producing the condition of warping, increase of service life.
