[0060] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below in conjunction with the accompanying drawings through specific implementation methods. Figure 5 The orientation is used as a reference.

[0061] See also Figure 1-7 The utility model provides an integrated stove, comprising a cooking box, a smoke exhaust fan and a multifunctional steam generator. The multifunctional steam generator comprises a housing 1, a water inlet coil 3, a heating tube 2 and a switch 4.

[0062] The housing 1 has a vaporization chamber 120, and a steam exhaust port 111 and a steam inlet port 123 are provided on the housing 1 and are connected to the vaporization chamber 120. The steam exhaust port 111 is connected to the cooking box and is used to supply steam and hot water to the cooking box. The water inlet coil 3 is fixed inside the wall of the housing 1, and the water inlet end 31 and the water outlet end 32 of the water inlet coil 3 are both connected to the outside of the housing 1. The heating pipe 2 is fixed inside the wall of the housing 1, and the heating pipe 2 heats the water inlet coil 3 and the vaporization chamber 120 through the housing 1. The switch 4 is fixed to the outside of the housing 1. The switch 4 is provided with a water inlet channel 423, a first water outlet channel 411, and a second water outlet channel 422. The water inlet channel 423 is also connected to the water outlet end 32. The first water outlet channel 411 or the second water outlet channel 422 is connected to the water inlet channel 423.

[0063] The first water outlet channel 411 is connected to the smoke exhaust fan for supplying steam and hot water to the smoke exhaust fan. The second water outlet channel 422 is connected to the steam inlet 123 .

[0064] This multifunctional steam generator has two functions: supplying steam or a mixture of steam and hot water to the cooking compartment and the exhaust fan:

[0065] When in use, water is passed into the water inlet coil 3 from the water inlet end 31 of the water inlet coil 3 , and the heating tube 2 heats the water inlet coil 3 and the vaporization chamber 120 through the shell 1 .

[0066] When the multifunctional steam generator supplies steam to the cooking box, the second water outlet channel 422 of the switch 4 is connected to the water inlet channel 423. Water is heated while flowing in the water inlet coil 3 to become a mixture of hot water and steam, and the mixture enters the vaporization chamber 120 through the water outlet end 32, the water inlet channel 423, the second water outlet channel 422 and the steam inlet port 123 in sequence, and the steam in the mixture is discharged into the cooking box through the steam outlet 111, and the hot water is heated again in the vaporization chamber 120 to form steam, and is passed into the cooking box through the steam outlet 111, so as to supply the cooking box with a mixture of hot water and steam required for cooking.

[0067] When the multifunctional steam generator supplies a mixture of steam and hot water to the smoke exhaust fan, the first water outlet channel 411 of the switch 4 is connected to the water inlet channel 423. The water is heated while flowing in the water inlet coil 3 to become a mixture of hot water and steam, and the mixture is sequentially passed through the water outlet end 32, the water inlet channel 423, and the first water outlet channel 411 into the smoke exhaust fan, supplying the smoke exhaust fan with a mixture of hot water and steam required for cleaning.

[0068] As can be seen from the above, the integrated stove is only equipped with a multifunctional steam generator, which can provide the cooking box with the steam required for cooking and the mixture of steam and hot water for the oil exhaust fan to clean the oil stains, thereby simplifying the size of the device and reducing costs.

[0069] Furthermore, when the multifunctional steam generator supplies a mixture of hot water and steam to the cooking box, it includes two modes: instant heating mode and water boiling mode.

[0070] Among them, the instant heating mode is:

[0071] Water is passed into the water inlet coil 3 from the water inlet end 31 of the water inlet coil 3, and the heating tube 2 heats the water inlet coil 3 and the vaporization chamber 120 through the shell 1: the water in the water inlet coil 3 is heated to form steam and is sent into the vaporization chamber 120 from the water outlet end 32 of the water inlet coil 3, and the unevaporated water in the water inlet coil 3 is sent into the vaporization chamber 120, the water in the vaporization chamber 120 is heated again to form steam, and the steam in the vaporization chamber 120 is passed into the cooking box from the steam exhaust port 111.

[0072] The water boiling modes are:

[0073] Water is supplied to the water inlet end 31 of the water inlet coil 3. After a certain amount of water is supplied into the vaporization chamber 120 through the water outlet end 32 of the water inlet coil 3, the heating tube 2 heats the vaporization chamber 120 through the shell 1. The water in the vaporization chamber 120 is heated and evaporated into water vapor, and the water vapor is passed into the cooking chamber of the cooking box through the steam exhaust port 111.

[0074] In summary, the dual-mode steam generator can realize two modes, namely, instant heating mode and water boiling mode, to meet the different needs of users.

[0075] At the same time, when the multifunctional steam generator supplies a mixture of hot water and steam to the cooking box, the instant heating mode is adopted in the initial stage, and the water inlet speed of the water inlet coil 3 is controlled so that the water inlet coil 3 discharges the mixture of steam and water into the vaporization chamber 120 to quickly provide steam. After a period of operation, a certain amount of water accumulates in the vaporization chamber 120. Subsequently, the water is switched to the boiling mode, and the water inlet to the water inlet coil 3 is stopped. The vaporization chamber 120 is heated by the heating tube 2 through the housing 1, and the water in the vaporization chamber 120 evaporates into water vapor to continuously supply steam. In the initial stage of the instant heating mode, a mixture of steam and hot water is generated in the water inlet coil 3. The hot water can wash away the scale brought into the water inlet coil 3 to avoid the scale blockage in the water inlet coil 3. When in use, water is always passed through the water inlet coil 3 and / or the vaporization chamber 120 to avoid the discontinuity of steam caused by the dry burning of the heating tube 2 and the power failure. The water in the water inlet coil 3 is heated while flowing to form steam, and the speed of forming steam is relatively fast.

[0076] Specifically, the first water outlet channel 411 is connected to the cleaning pipeline of the smoke exhaust fan through a pipeline, and provides a mixture of hot water and steam for cleaning oil stains to the smoke exhaust fan.

[0077] Preferably, the heating tube 2 is an electric heating tube.

[0078] Furthermore, the housing 1 includes a bottom shell 12 and a cover body 11 .

[0079] The bottom shell 12 has a vaporization chamber 120 with an opening facing upward, and the cover body 11 is disposed on the vaporization chamber 120 .

[0080] The water inlet coil 3 and the heating tube 2 are fixed inside the wall of the bottom shell 12. The steam exhaust port 111 is opened on the cover body 11.

[0081] Specifically, a sealing gasket 13 for sealing a gap between the cover 11 and the bottom shell 12 is sandwiched between the cover 11 and the bottom shell 12. Preferably, the cover 11 and the bottom shell 12 are connected by screws.

[0082] Specifically, the bottom shell 12 includes a heat transfer bottom plate 121 and a surrounding plate 122 surrounding the heat transfer bottom plate 121 in the circumferential direction. The heat transfer bottom plate 121 and the surrounding plate 122 enclose a vaporization chamber 120. A steam inlet 123 is provided on the surrounding plate 122.

[0083] The heating tube 2 and the water inlet coil 3 are arranged vertically and fixed in the heat transfer bottom plate 121 to reduce the size of the device. The heating tube 2 heats the heat transfer bottom plate 121, and the heat transfer bottom plate 121 heats the water inlet coil 3 and the vaporization chamber 120.

[0084] More specifically, the bottom shell 12 is an aluminum alloy bottom shell, and the water inlet coil 3 and the heating tube 2 are cast in the heat transfer bottom plate 121 .

[0085] Specifically, the heat transfer bottom plate 121 is provided with a drainage channel 124 communicating with the vaporization chamber 120, and the excess water in the vaporization chamber 120 is drained through the drainage channel 124. Preferably, the drainage channel 124 is vertically arranged and extends to the bottom of the heat transfer bottom plate 121 for easy drainage.

[0086] When in use, the multifunctional steam generator generates a mixture of steam and hot water in the initial stage of the instant heating mode, and the hot water can wash the scale in the water inlet coil 3 into the vaporization chamber 120. After use, the drainage channel 124 at the bottom of the bottom shell 12 washes away the scale when discharging waste water, thereby avoiding the scale blockage in the water inlet coil 3. The existing instant heating steam generator outputs pure steam, which cannot take away the scale in the pipeline.

[0087] Preferably, a temperature sensor 14 for monitoring the temperature of the heat transfer bottom plate 121 is disposed outside the heat transfer bottom plate 121 to stop heating when the heating tube 2 is dry and burns out due to lack of water, thereby preventing damage to the heating tube 2. More preferably, the temperature sensor 14 is disposed on the outer bottom wall of the heat transfer bottom plate 121.

[0088] Furthermore, the switch 4 has a switching chamber 421, which is connected to the first water outlet channel 411, the second water outlet channel 422 and the water inlet channel 423. A switching member 433 for closing the first water outlet channel 411 or the second water outlet channel 422 is arranged in the switching chamber 421.

A switching chamber 421 and a through chamber 424 connecting the switching chamber 421 and the second water outlet channel 422 are provided on the valve body 42. The driving assembly 43 includes a driving body 431, a valve stem 432 and a switching member 433. The switching member 433 is a valve plate. The driving body 431 is fixed to the valve body, and the driving body 431 is connected to the valve stem 432. The valve stem 432 is inserted into the through chamber 424 and the switching chamber 421 so as to be movable relative to the through chamber 424 and the switching chamber 421, and the valve stem 432 is fixedly connected to the switching member 433 located in the switching chamber 421.

[0091] The driving body 431 is used to transmit a driving force to the valve stem 432 relative to the through cavity 424 and the switching cavity 421 . The valve stem 432 can drive the switching member 433 to move to a position closing the first water outlet channel 411 or the second water outlet channel 422 .

[0092] When the valve stem 432 drives the switching member 433 to move to abut the communication port between the switching chamber 421 and the first water outlet channel 411, the first water outlet channel 411 is closed and the second water outlet channel 422 is opened. When the valve stem 432 drives the switching member 433 to move to abut the communication port between the switching chamber 421 and the through chamber 424, the second water outlet channel 422 is closed and the first water outlet channel 411 is opened.

[0093] Specifically, the valve cover 41 is fixedly connected to the driving member and the valve body 42 by screws. The valve cover 41 or the valve body 42 is fixedly connected to the outside of the housing 1 by screws.

[0095] The driving body 431 is used to transmit the driving force for the valve stem 432 to move up and down relative to the through cavity 424 and the switching cavity 421: when the valve stem 432 drives the switching member 433 to move down to abut the connecting port between the switching cavity 421 and the first water outlet channel 411, the first water outlet channel 411 is closed and the second water outlet channel 422 is opened. When the valve stem 432 drives the switching member 433 to move up to abut the connecting port between the switching cavity 421 and the through cavity 424, the second water outlet channel 422 is closed and the first water outlet channel 411 is opened.
