Comparing fig. 4 and fig. 11, when the water purification module 2 is integrated inside, the external connection pipeline of the integrated stove is less and simple, the space in the integrated stove is more compactly utilized, and the space below the water tank 30 can be left for other purposes. In the integrated kitchen of externally connecting the water purifier, the external connection pipeline is more, and the exterior space that occupies is great, but the space in the integrated kitchen is more loose, has set up upper and lower electric steamer and electric oven in fig. 11 for example, has still set up locker 3, can integrate more functional modules. It should be noted that, in the integrated cooker, the internal or external water purification module 2 may be a pressure tank or a pressure tank-free water purification module, and may be a plurality of filter element combination schemes, which are not critical in this case, and detailed description is omitted here.

Referring to fig. 13, 14, in one embodiment, the integrated cooker includes:

a steam cooking module;

a steam washing module 6; and

a common steam generator 10, the common steam generator 10 being switchable between a low heating power state or a high heating power state;

wherein, in a low heating power state, the common steam generator 10 generates a steam mixture and delivers it at least to the steam wash module 6, and in a high heating power state, the common steam generator 10 generates high temperature steam and delivers it at least to the steam cooking module.

In the present embodiment, the common steam generator 10 within the integrated hob provides steam to the different steam usage modules and may provide different forms of steam. For example, in fig. 13, 14, the steam cooking module is illustratively supplied with high temperature steam, i.e., fully vaporized pure steam, typically above 100 ℃, and the steam wash module 6 is supplied with a relatively high moisture and relatively low temperature vapor mixture having a relatively large amount of entrained moisture. Like this, can practice thrift functional components and parts, practiced thrift steam generator promptly, not only practiced thrift the components and parts cost, more importantly provides more loose installation space in the finite space of integrated kitchen, has made things convenient for the structural layout design of product.

The low heating power state and the high heating power state are a mutual comparison value, the heating efficiency in the high heating power state is higher than that in the low heating power state, so that high-temperature steam, namely pure steam generally higher than 100 ℃, is generated in the high heating power state, and a steam-state steam-water mixture of partial steam and partial steam is generated in the low heating power state, and the water content of the steam-state steam-water mixture is much larger than that of the pure steam.

To achieve multi-power heating, as an example, the common steam generator 10 may include a boiler and a plurality of electric heating elements arranged at a circumferential wall of the boiler, a part of the plurality of electric heating elements being electrically operated in a low heating efficiency state, and the whole of the plurality of electric heating elements being electrically operated in a high heating efficiency state. The electric heating element can be an electric heating tube which is cheap, easily available and easy to assemble, but also can be a thick film heating element and the like. In addition, the low heating power state or the high heating power state may be internalized and subdivided into a plurality of low heating power states or a plurality of high heating power states of different sizes, which is not intended to limit the present invention.

To achieve back-end steam distribution of the common steam generator 10, in one embodiment, as shown in fig. 13, the integrated hob includes a three-way connector 20, the three-way connector 20 having one inlet end and two outlet ends communicating with both inlet ends. The inlet end of the three-way connector 20 is connected with the steam outlet end of the common steam generator 10, a first branch steam supply pipe is connected between the first outlet end of the three-way connector 20 and the steam cooking module, and a second branch steam supply pipe is connected between the second outlet end of the three-way connector 20 and the steam washing module 6.

Similarly, more flow allocations can be made through more channels of the multi-way connector and its supply valve.

Generally, the steam box module 1 and the steam washing module 6 are not activated at the same time, so the first and second air supply valves are normally in a closed-open state or in a closed-open state at the same time. On this basis, the integrated hob further comprises a steam supply controller 100, the steam supply controller 100 being configured to:

correspondingly selecting the heating power state of the common steam generator 10 according to the working states of the steam washing module 6 and the steam cooking module;

controlling the common steam generator 10 to be in a low heating power state to generate and deliver the water-vapor mixture when the steam washing module 6 is independently started;

when the steam cooking module is separately activated, the common steam generator 10 is controlled to be in a high heating power state to generate and deliver high temperature steam.

Of course, the case where the steam box module 1 and the steam wash module 6 are simultaneously activated is not excluded, and thus the steam supply controller 100 may be further configured to: when the steam washing module 6 and the steam cooking module are jointly started, the common steam generator 10 is controlled to be in a high heating power state. At the moment, the steam washing module 6 adopts high-temperature steam spray washing to soften oil stains on the surface of the air duct assembly at high temperature.

In another embodiment, the integrated cooker may include a multi-way directional valve 14, an inlet end of the multi-way directional valve 14 is connected to a steam outlet end of the steam generator, a first branch steam supply pipe is connected between a first outlet end of the multi-way directional valve 14 and the steam cooking module, and a second branch steam supply pipe is connected between a second outlet end of the multi-way directional valve 14 and the steam washing module 6. The inlet side of the multi-way diverter valve 14 is selectively controllable to selectively communicate with one of the outlet sides, thereby providing fewer control components and greater ease of control than the three-way connector 20 and its combination of two supply valves.

After the common steam generator 10 is used, the integrated cooker further includes an internally integrated water purification module 2 for supplying purified water to the common steam generator 10. The water purification module 2 may directly supply water, or the integrated cooker may also include a built-in water storage box 8 temporarily storing purified water through the built-in water storage box 8 and disposed in a connection pipe between the purified water outlet a1 of the water purification module 2 and the common steam generator 10.

Thus, the pipe connection with the water purifier or the water purification module is realized through the built-in water storage box 8, the water storage box inlet valve 81 and the steam generator water supply pump 17.

In order to control the water inflow and the water supply time, the integrated cooker can further comprise a water supply controller, and the water supply controller is configured as follows:

when the steam cooking module or the steam washing module 6 is started to work, the water inlet valve 81 of the water storage box is opened in a linkage mode, when the water level in the built-in water storage box 8 reaches a preset water level, the water inlet valve 81 of the water storage box is stopped, and the water supply pump 17 of the steam generator is started at the same time.
