In order to solve the problems of complicated water changing of the water box of the steam oven, heavy metal residue and the like, as shown in fig. 2, the invention provides that purified water produced by a water purifier or a water purifying module 2 is conveyed into a steam generator of the steam oven or a steam box module 1 through a purified water interface 43, so as to replace a water box 11 which is assembled and disassembled by manual water changing, and simultaneously, the problems of more residues on the surface of food after steam cooking, scale deposition after the steam generator is used for a long time and the like are solved. The water purifier or the water purification module 2 may be connected to a municipal tap water pipe through a tap water connection 41 and discharge residual water through a residual water discharge port 42, and may also deliver prefiltered or purified water to the faucet 9.

The water purifier and the steam boiler can be independent products, are only connected through a pipeline and are in linkage control, and can also be integrated in an integrated stove as functional modules respectively. The water purifier can comprise a multi-stage filter element capable of filtering silt, heavy metal ions and calcium and magnesium ions, and provides purified water for the steam boiler, so that heavy metal pollution, scale deposition and the like are avoided.

Referring to fig. 5, the linkage system includes:

the water purifier is provided with a purified water outlet pipe L1; and

a steam oven including a steam generator;

wherein, a purified water outlet pipe L1 is connected to the steam generator to provide a source of steam water.

As shown in fig. 8, in an embodiment, a multi-way reversing valve 14, such as a three-way reversing valve or a four-way reversing valve, may be disposed in the purified water outlet pipe L1, the multi-way reversing valve 14 includes at least a first outlet end connected to the steam generator and a second outlet end for draining or supplying water, and a metering pump 15 is disposed in a connecting pipe between the first outlet end and the steam generator. Thus, one path of the purified water outlet pipe L1 supplies water to the steam boiler, and the other path can be used for temporary storage or direct supply of the water tap 9. Therefore, the system may further include a drinking water tap 92 or a purified water storage box 16 connected to the second outlet end of the purified water outlet pipe L1.

The water purifier may include a water purifier controller. When in use, the water purifier controller is configured to synchronously start and continuously output the purified water after receiving a starting signal of the steam boiler; correspondingly, the steam oven can comprise a steam oven controller, and the steam oven controller is configured to select the corresponding pure water set consumption according to the steam cooking gear and control the multi-way reversing valve 14 to be switched to the first outlet end; the corresponding purified water with the set dosage is metered and input through a metering pump 15; the multi-way reversing valve 14 is controlled to switch to other outlet ports, such as a second outlet port or possibly a third outlet port, etc.

Wherein, the steam oven can be selected etc. according to culinary art edible material and duration and set for different steam cooking gears, corresponds the required steam water consumption of different magnitudes (being the pure water and sets for the quantity). Or the steam oven can calculate more refined steam water consumption according to parameters such as cooking time, heating efficiency of the steam generator and the like, so that the steam oven can be used as a pure water set consumption signal to be generated to the water purifier controller.

When the multi-way reversing valve 14 is arranged, the water purifier can generate pure water with the set consumption of redundant pure water, and the redundant pure water can be output through the second outlet end and the like. Alternatively, purified water may be quantitatively produced and quantitatively delivered. As shown in fig. 9, a steam generator water supply pump 17 at an upstream end of the steam generator is provided in the purified water outlet pipe L1; wherein, the steam oven controller is configured to select the corresponding pure water setting dosage according to the steam cooking gear, and the water purifier controller is configured to receive the pure water setting dosage signal, generate the pure water of the pure water setting dosage and supply all quantitative to the steam generator through the steam generator water supply pump 17, thereby realizing the graded, accurate and quantitative water supply.

When supplying water to the steam generator, the power device may be a metering pump 15 provided at the front end of the steam generator, a steam generator water supply pump 17, or the like, but may be a pump by pumping power in the water purifier. Taking fig. 9 as an example, the steam generator water supply pump 17 may be omitted. A booster pump 22 is provided in the water purifier, and the water purifier includes a water purifier controller configured to be synchronously activated upon receiving a start signal of the steam boiler to generate purified water, and to control driving of the booster pump 22 to pump the purified water to the steam generator through a purified water outlet pipe L1. The direct pumping of the booster pump 22 in the water purifier can reduce the use of components and save the installation space.

In another alternative embodiment, as shown in fig. 5, a built-in water storage box 8 is particularly added to the purified water outlet pipe L1, and a cooking water supply pump 13 is provided in a connection pipe between the built-in water storage box 8 and a steam generator of the steam oven. Namely, the purified water is temporarily stored by the built-in water storage box 8 and then distributed or discharged.

Different from the water box 11, the built-in water storage box 8 can be fixed without disassembly, replacement, manual water adding, water pouring and the like. The water storage cavity of the built-in water storage box 8 can be communicated with the outside, and a water storage box inlet valve 81 is arranged in a purified water outlet pipe L1 connected with the inlet end of the built-in water storage box 8. Thus, when the water inlet valve 81 of the water storage box is opened, which is equivalent to the opening of the water tap, the purified water of the purified water outlet pipe L1 can be input into the built-in water storage box 8.

Of course, it will be understood by those skilled in the art that the built-in water storage box 8 may be additionally provided in the embodiment shown in fig. 8 and 9.

Wherein, water purifier and steam oven can integrate in same integrated kitchen, and integrated kitchen still can include other functional module, as shown in fig. 3. Accordingly, the built-in water storage box 8 includes a first outlet port connected to the steam generator, a second outlet port connected to other functional modules, and the like. As shown in fig. 6, 7, other functional modules may be included in the dishwasher module 7, the steam wash module 6, or both. Similarly, the pure water is adopted, so that the residue of heavy metal on bowls and chopsticks and the volute fan can be reduced. In addition, the steam oven can be integrated in the integrated kitchen, and the water purifier is located outside the integrated kitchen.

The linkage principle of the water purifier and the steam boiler is explained above, and on the basis, the invention correspondingly provides the integrated stove with different integration degrees.

In order to solve the problems that after the integrated stove is used for a long time, oil smoke is attached to an impeller of an oil smoke exhaust device, the exhaust amount of the whole machine is reduced, and the oil smoke cleaning rate is reduced, a part of the integrated stove has the function of automatically cleaning the impeller by using steam, and the integrated stove can be kept to operate efficiently for a long time. Because the water quality of each region is different, after the integrated kitchen range of some regions is used for a long time, a large amount of water scales can be generated in the evaporation pan or the steam generator cavity for generating steam, the heating efficiency of the evaporation pan or the steam generator is reduced, and even pipelines are blocked in serious cases, so that the product is invalid.

As shown in fig. 3 and 4, an integrated cooker integrated with a water purification module 2 according to an embodiment of the present invention is disclosed, the integrated cooker including:

a steam cooking module including a steam generator; and

and a water purification module 2 including a filtered purified water outlet a1, the purified water outlet a1 being connected to the steam generator to provide a source of steam water.

It can be seen that, in the integrated cooker integrated with the water purification module 2, the water purification module 2 provides purified water as a steam water source for the steam cooking module. The steam cooking module may include an electric steamer, an electric oven, and the like, but is not limited thereto. The steam cooking module (fig. 4 shows as a steam box module 1) and the water purification module 2 can be distributed side by side in the front of the integrated cooker, and the rear of the integrated cooker is provided with a head part 5 and a fan assembly (not shown) and the like. Integrated kitchen is including integrated kitchen shell body 4, and the water interface of all kinds can set up on integrated kitchen shell body 4, is equipped with running water interface 41 and residual water outer row mouth 42 on the lateral wall of integrated kitchen shell body 4 for example. As can be seen from fig. 5, the water purification module 2 has a purified water outlet a1, a domestic water outlet a2, a concentrated water outlet A3, etc., which are respectively connected to a purified water outlet pipe L1, a domestic water outlet pipe L2, and a concentrated water outlet pipe L3. The top of the integrated stove outer shell 4 can be provided with a life tap 91 connected with the life water outlet A2 of the water purification module 2 and a drinking water tap 92 connected with the purified water outlet A1. A life tap 91 and a drinking water tap 92 are disposed above the sink 30 in the lateral direction of the integrated kitchen. Wherein the living water is primarily filtered and can be used for washing clothes and vegetables; the drinking water is subjected to RO reverse osmosis filtration to remove heavy metals, calcium ions and magnesium ions, and can be used for cooking or drinking; the concentrated water is the waste water produced in the process of producing drinking water and is discharged into a drain pipe.

In the integrated stove integrated with the water purification module, tap water is externally connected through a tap water interface 41 to enter the integrated stove, and is purified by the water purification module 2 to supply water to the steam box, so that water is not required to be added in advance by independently dismounting the water box 11, and residual water is not required to be emptied after the steam box is used, so that the integrated stove is more convenient to use; meanwhile, the water supplied to the steam box is purified drinking water, the content of heavy metal ions is greatly reduced, and the steamed food is more sanitary.

Particularly, the integrated cooker further comprises a built-in water storage box 8 for temporarily storing purified water, wherein an inlet end of the built-in water storage box 8 is connected with the purified water outlet A1, and an outlet end of the built-in water storage box 8 is connected with the steam generator. The built-in water storage box 8 can be drawn out like the detachable water box 11 in fig. 1, and water can be filled or poured manually. However, in the present embodiment, the built-in water storage box 8 is fixedly disposed in the integrated oven, and water inlet and water outlet are controlled by disposing a pipeline with a pump or a valve, so as to achieve automation and improve user satisfaction.

As shown in fig. 5, the water storage cavity of the built-in water storage box 8 is communicated with the outside, a water inlet valve 81 of the water storage box is arranged in a water inlet pipe section of the built-in water storage box 8, the outlet end of the built-in water storage box 8 is connected with a cooking water supply pipe 12, and a cooking water supply pump 13 is arranged in the cooking water supply pipe 12; wherein the steam cooking module includes a cooking controller configured to open the water storage box inlet valve 81 when the steam cooking module is started to operate, and stop the water storage box inlet valve 81 and start the cooking water supply pump 13 when the water level in the built-in water storage box 8 reaches a preset level.

Since the built-in water storage box 8 is communicated with the outside, the purified water in the purified water outlet pipe L1 can be introduced into the built-in water storage box 8 when the water inlet valve 81 of the water storage box is opened. In fig. 5, when the water inlet valve 81 of the water storage box is closed, purified water is stopped from being introduced into the built-in water storage box 8, and purified water can be guided to the faucet 9.

Further, the integrated cooker of the present embodiment further includes a steam washing module 6, a steam washing water supply pipe 61 is connected between the steam washing module 6 and the outlet end of the built-in water storage box 8, and a steam washing water supply pump 62 is disposed in the steam washing water supply pipe 61. Similarly, wash module 6's steam generator with the leading-in steam of pure water, because the pure water is the drinking water through purifying, calcium, magnesium ion content greatly reduced can avoid steam generator's boiler scale deposit when using for a long time, extension complete machine life, still can avoid the heavy metal to remain on turbine spiral case surface.

As an example, the steam wash module 6 may include a steam wash controller configured to open the water storage cartridge inlet valve 81 when the steam wash module 6 is activated, and to stop the water storage cartridge inlet valve 81 and open the steam wash water pump 62 to direct purified water to the steam wash module 6 when the water level in the built-in water storage cartridge 8 reaches a preset level.

It should be noted that the preset water level may be the maximum allowable water level in the built-in water storage box 8, or may be a corresponding different accurate measurement value corresponding to different cooking materials, cooking time, steam generator heating power, steam washing time and other factors. The preset water level should be equal to or slightly greater than the accurate metering value.

In one embodiment shown in fig. 6, the water purification module 2 may further include a domestic water outlet pipe L2, and the domestic water outlet pipe L2 is connected to the steam wash module 6. The primary filtered domestic water of the domestic water outlet pipe L2 can be introduced into the steam washing module 6, and the spray washing or immersion washing and the like can be carried out on the turbine volute, the inner wall surface of the air duct and the like in combination with the steam washing.

In an embodiment shown in fig. 7, the integrated cooker may also include a dishwasher module 7, the dishwasher module 7 is connected to the water storage chamber of the built-in water storage box 8 through a pipeline, and a dishwasher water supply pump 71 is disposed in the connecting pipeline. Therefore, the introduced purified water is purified drinking water, the contents of calcium ions, magnesium ions and heavy metal ions are greatly reduced, and compared with tap water cleaning, the heavy metal residues on the surfaces of the dish washing cavity and the bowls and chopsticks can be greatly reduced, and the accumulation of scale is also avoided.

In fig. 5 to 7, the water purification module 2 further includes a concentrated water drain pipe L3, the built-in water storage box 8 may include a water storage box drain pipe L6 connected to the concentrated water drain pipe L3, a water storage box drain pump 82 is disposed in the water storage box drain pipe L6, and the water storage box drain pump 82 can pump and drain accumulated water in the box, so as to prevent the accumulated water from smelling after long-term non-use. Accordingly, the cooking controller is configured to activate the water storage box drain pump 82 in conjunction with the stop of the steam cooking module to drain the stored water in the built-in water storage box 8. Alternatively, the water storage box drainage pump 82 may be configured to drain the water stored in the built-in water storage box 8 periodically, for example, every 12 hours periodically, or the steam box may be used for 24 hours periodically.

When the inside integration has water purification module 2, the external connection pipeline of integrated kitchen is still less and succinct, and the space in the integrated kitchen is compacter to be utilized, and the below space of basin 30 can remain for other uses. Certainly, also can be at integrated kitchen external connection water purifier, but the external connection pipeline is more, and the exterior space that occupies is great, and the advantage is that the space in the integrated kitchen is more loose, can integrate more functional module. 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. 10, 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. 10, 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 humidity, relatively low temperature, vaporous water vapor mixture that entrains a relatively large amount of water vapor. 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 operated electrically in a low heating efficiency state, and the plurality of electric heating elements being operated all electrically 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 also be internally subdivided into a plurality of low heating power states or a plurality of high heating power states of different sizes, to which the present invention is not limited.

To achieve back-end steam distribution of the common steam generator 10, in one embodiment, as shown in fig. 10, 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.

Wherein, a first steam supply valve 201 is arranged in the first branch steam supply pipe, a second steam supply valve 202 is arranged in the second branch steam supply pipe, steam generated by the common steam generator 10 enters the three-way connector 20 from the inlet end and flows out from the two outlet ends respectively in two parts, and the flow rate flowing to the steam washing module 6 and the steam cooking module (including but not limited to the steam box module 1) is adjusted by the two steam supply valves. 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;

the first steam supply valve 201 and the second steam supply valve 202 are correspondingly controlled by the switches according to the working states of the steam washing module 6 and the steam cooking module.

Further, the steam supply controller 100 is further configured to:

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, it is not excluded that the steam box module 1 and the steam wash module 6 are started simultaneously, and therefore the steam supply controller 100 may also be 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 this moment, the steam washing module 6 adopts high-temperature steam spray washing to soften the surface oil stain 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.

In addition, the pure water may be pumped to each function module by using a booster pump 22 or the like within the water purification module 2 to provide power. By utilizing the pumping power of the booster pump 22, a preposed water supply pump of the steam generator, a built-in water storage box and the like can be saved, the use of components is reduced, the cost of the components is reduced, the limited installation space in the integrated kitchen is saved, and the internal layout design of the product is convenient.

The water purifier or the water purification module 2 has different internal water paths and can have various forms of filter elements. The water purification module 2 of the present invention employs a typical waterway system, as shown in fig. 5 to 9.

As an example, referring to fig. 5, the water purification module 2 therein includes:

the water outlet end of the internal main water pipe L0 is connected with a purified water outlet pipe L1; and

the RO filter cartridge 23 is disposed in the inner main water pipe L0 in series with the booster pump 22 and is located at the downstream end of the booster pump 22.

Wherein, the booster pump 22 pumps the water under pressure to the RO filter element 23 for reverse osmosis filtration to generate purified water and concentrated water.

Further, water purification module 2 still includes:
