[0029] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0030] Example 1:

[0031] For steam generators, please refer to [link / reference]. Figure 1-3 As shown, it includes: a main body 100; the main body 100 has an internal chamber 200, and an outlet 300 at the top connecting the chamber 200; a partition 400 is provided inside the main body 100, which divides the chamber 200 into a water supply chamber 210 and a heating chamber 220; the partition 400 is provided with a water inlet 410 connecting the water supply chamber 210 and the heating chamber 220;

[0032] The water replenishment chamber 210 is provided with a water inlet 211 and a float valve 500, and the float valve 500 controls the opening / closing of the water inlet 211;

[0033] A heating element 600 is provided inside the heating chamber 220.

[0034] Specifically, such as Figure 1 and Figure 3 As shown, the main body 100 can be designed as a cylinder with a bottom surface and a side wall perpendicular to the bottom surface, so that a chamber 200 is formed inside the main body 100, and the top of the main body 100 forms an outlet 300.

[0035] The main body 100 can be made of metal, such as stainless steel, which has properties such as high temperature resistance and corrosion resistance;

[0036] Alternatively, the main body 100 may also have other shapes, such as rectangles, etc.

[0037] In this embodiment, as shown Figure 1 As shown, the top of the main body 100 is designed as an outlet 300. The top of the main body 100 has no cover plate. Optionally, a cover plate can be provided on the top of the main body 100, and the outlet 300 can be opened on the cover plate.

[0038] like Figure 1 and Figure 3 As shown, the partition 400 is connected to the inner side wall and the bottom wall of the chamber 200 to divide the chamber 200 into a water supply chamber 210 and a heating chamber 220. The partition 400 has a water supply port 410 from the bottom to the top. The water supply port 410 can be set at the middle position in the length direction of the partition 400.

[0039] Of course, the water inlet 410 can also be positioned to the left or right of the partition 400.

[0040] The water inlet 410 is arranged as close as possible to the inner bottom wall of the chamber 200;

[0041] The float valve 500 uses existing technology, and its specific structure and principle will not be described in detail here.

[0042] In use, the inlet 211 is connected to an external water source. The float 510 of the float valve 500 always floats on the water. When the water level rises, the float 510 also rises, which in turn drives the connecting rod to swing. The connecting rod is connected to the valve. When the float 510 rises to the second water level line, the connecting rod swings to close the valve, that is, the inlet 211 is closed. When the water level drops, the float 510 falls, which drives the connecting rod to swing. When the float 510 falls to the first water level line, the connecting rod swings to open the valve, that is, the inlet 211 is opened, and the external water source is injected into the water replenishment chamber 210.

[0043] The heating element 600 is powered on and heats up the water in the heating chamber 220. The heated water in the heating chamber 220 is steam, which is sent out from the outlet 300 to a designated place.

[0044] After the water in the heating chamber 220 evaporates, the water in the water replenishment chamber 210 is supplied to the heating chamber 220. The water inlet 410 keeps the liquid levels in the water replenishment chamber 210 and the heating chamber 220 at the same height. As can be seen from the above, when the water level in the water replenishment chamber 210 drops to the first water level line, the float valve 500 controls the water inlet 211 to open, and the external water source is injected into the water replenishment chamber 210.

[0045] The second water level is higher than the first water level.

[0046] In one embodiment, the left and right sides of the partition 400 are arc-shaped; the left and right sides of the partition 400 are connected to the inner wall of the chamber 200.

[0047] like Figure 3 The left side 401 and right side 402 of the partition 400 are arranged in an arc shape, which effectively reduces the impact on the partition 400 when the hot water in the heating chamber 220 boils.

[0048] Continue as Figure 3 As shown, in this embodiment, the left side 401 and right side 402 of the partition 400 are bent towards the heating chamber 220, that is... Figure 3 It is roughly curved to the lower left and lower right.

[0049] In one embodiment, the volumes of the heating chamber 220 and the water replenishment chamber 210 may be equal, or the volume of the water replenishment chamber 210 may be greater than the volume of the heating chamber 220; or the volume of the heating chamber 220 may be greater than the volume of the water replenishment chamber 210.

[0050] In this embodiment, the volume of the heating chamber 220 is set to be larger than the volume of the water replenishment chamber 210 to ensure the amount of water in the heating chamber 220 and the amount of steam produced.

[0051] In one embodiment, the heating element 600 is a heating coil, and the heating element 600 is disposed near the bottom of the heating chamber 220;

[0052] Figure 3 The heating coil is coiled in the middle, which can effectively improve heating efficiency.

[0053] Alternatively, the heating coils can be configured in a separate manner with multiple coils.

[0054] In one embodiment, the height of the partition 400 is lower than the height of the main body 100, which saves materials to some extent.

[0055] Example 2:

[0056] An electric heating device includes: a body 700 and the aforementioned steam generator installed on the body 700; the body 700 can be an electric heating cage, an electric heating steamer, an electric heating insulation table, etc.

[0057] Example 3:

[0058] An electric heating device, such as Figure 4 As shown, it is specifically an electric heating and heat preservation table, including: a body 700 and a steam generator of embodiment 1, the steam generator being installed inside the body 700;

[0059] The main body 700 has a cabinet 730, which is a cabinet structure with braked casters at the bottom for easy movement and positioning. Components such as the steam generator, electronic board, and control box are installed inside the cabinet 730. The surface of the cabinet 730 can be equipped with control panels, control knobs, control buttons, indicator lights, and other structures.

[0060] The top of the body 700 forms a heat preservation platform, which includes multiple heat preservation chambers 710 with upward openings. A steam outlet pipe 720 is provided in the heat preservation chamber 710. The steam outlet pipe 720 has a steam outlet hole 721 and is connected to the outlet 300 of the steam generator.

[0061] like Figure 4 As shown, in this embodiment, the heat preservation platform is provided with six heat preservation chambers 710. The number of heat preservation chambers 710 can be changed to other numbers according to actual needs.

[0062] A steam generator is installed inside the body 700. One steam generator can be installed, and one steam generator can supply steam to six insulated chambers 710. The outlet 300 of the steam generator can be connected to the six insulated chambers 710 respectively through a multi-port pipe to supply steam to the insulated chambers 710. A control valve is installed on the multi-port pipe to control the supply of steam to the six insulated chambers 710 individually or to certain designated insulated chambers 710.

[0063] Optionally, one steam generator may be provided for each insulation chamber 710, so six steam generators are provided for six insulation chambers 710. The six steam generators operate independently, so each insulation chamber 710 can operate independently for insulation.

[0064] Optionally, a steam generator can be provided for every two insulated chambers 710, so that one steam generator supplies steam to both insulated chambers 710.

[0065] Specifically, in this embodiment, one steam generator is selected for every two insulation chambers 710, so in this embodiment, three steam generators are installed in the body 700 to supply steam to the six insulation chambers 710.

[0066] Continue as Figure 4 As shown, a steam outlet pipe 720 is provided for every two insulation chambers 710. The steam outlet pipe 720 passes horizontally through the two insulation chambers 710. Multiple steam outlet holes 721 are evenly opened on the steam outlet pipe 720. Steam is sent out through the steam outlet pipe 720 and the steam outlet holes 721.

[0067] The container is placed in the heat-insulating chamber 710 to facilitate heating and heat preservation of the food inside the container;

[0068] Here, the container can refer to a steamer, stainless steel container, etc., and should be placed as needed.

[0069] Continue as Figure 4 As shown, each pair of insulated chambers 710 forms a group. Figure 4 The device is provided with three sets of heat-insulating chambers 710. Each set of heat-insulating chambers 710 is separated by a baffle 701. At the same time, the edge of the heat-insulating table is provided with a retaining edge 702. The baffle 701 and the retaining edge 702 work together to form a placement surface 703 for placing containers.

[0070] When in use, square containers, especially steamers, can be placed in rectangular placement surfaces 703, where steam heats and keeps the food inside the steamer warm.

[0071] Optionally, depending on the usage requirements, a container can be provided to fit the shape of the heat preservation chamber 710, with one container placed in each heat preservation chamber 710 to heat and keep the food inside the container warm.

[0072] In one embodiment, the heat-insulating chamber 710 is provided with a first drain outlet 711, which is mainly used to drain condensate. The first drain outlet 711 can be connected to a sewer through a pipe to directly discharge the condensate; or, the first drain outlet 711 can be connected to a wastewater collection tank through a pipe to collect wastewater.

[0073] Furthermore, a second drain outlet 712 is also provided inside the heat-insulating chamber 710; the position of the second drain outlet 712 is higher than the position of the first drain outlet 711, and the second drain outlet 712 is connected to a drain pipe;

[0074] The second drain outlet 712 is used to drain excess condensate. If the first drain outlet 711 fails to drain the condensate in time, the second drain outlet 712 can work together to drain the condensate. Alternatively, if the first drain outlet 711 is blocked and a large amount of water accumulates in the insulation chamber 710, the second drain outlet 712 can drain the condensate in time.

[0075] In one embodiment, a set of symmetrical sidewalls of the insulation chamber 710 each include: a vertical wall 714 and an inclined wall 715; the inclined wall 715 is connected to the vertical wall 714, and the two inclined wall surfaces 715 are far apart and inclined outward; the inclined wall surface 715 guides condensate back into the insulation chamber 710.

[0076] Figure 4 In the insulated chamber 710, although only one of a set of symmetrical sidewalls can be observed, the other should also include: vertical wall 714 and inclined wall 715.

[0077] In addition, continue as Figure 4 As shown, other kitchen utensils can also be installed on the warming platform, such as a pot 800 for making soy milk or porridge.

[0078] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.

[0079] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
