Description

Technical Field

[0001] The utility model relates to the technical field of integrated stoves, and in particular to a multi-outlet steam generator and an integrated stove. Background Art

[0002] Integrated stoves are generally composed of stoves, smoke exhaust devices and cooking boxes. Among them, in existing integrated stoves such as electric steam boxes and steam-bake all-in-one machines, the cooking box usually uses an external steam generator to provide steam for the cooking process. After the smoke exhaust device has been used for a period of time, the fan inside it is easy to adhere to a large amount of oil and dirt, resulting in reduced exhaust volume and increased noise. Therefore, the fan is usually cleaned by spraying water or steam.

[0003] An integrated stove with a smoke exhaust device cleaning function, in addition to a steam generator to provide the cooking box with the steam needed for cooking food, is also equipped with a separate steam generator or hot water device to provide steam or hot water for the fan of the smoke exhaust device. The configuration of two steam generators or a steam generator heating water device makes the integrated stove more complicated in structure and more expensive. Utility Model Content

[0069] 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. Fig.10 The orientation is used as a reference.

[0070] See also Figure 1-17 The multi-outlet steam generator proposed in the embodiment of the utility model includes a shell 1, a controller 2, a water inlet coil 3 and a heating tube 4.

[0071] The shell 1 is provided with a vaporization chamber 120, a diversion chamber 121, and a first channel 122 connecting the vaporization chamber 120 and the diversion chamber 121. The shell 1 is also provided with a first outlet 111 connected to the vaporization chamber 120 and a second outlet 123 connected to the diversion chamber 121. The water inlet coil 3 is fixed inside the wall of the shell 1, the water inlet end 31 of the water inlet coil 3 is connected to the outside of the shell 1, and the water outlet end 32 of the water inlet coil 3 is connected to the diversion chamber 121. The heating tube 4 is fixed inside the wall of the shell 1, and the heating tube 4 heats the water inlet coil 3 and the vaporization chamber 120 through the shell 1. The controller 2 is fixed on the diversion chamber 121, and is used to open the first channel 122 or the second outlet 123.

[0072] The first outlet 111 is connected to the steam inlet of the cooking box 400, and the second outlet 123 is connected to the first washer 501 of the fan 500 of the smoke suction and exhaust device.

[0073] The multi-outlet steam generator 100 includes two steam supply modes: steam supply from the first outlet and steam supply from the second outlet 123:

[0074] In the first outlet steam supply mode, the controller 2 opens the first channel 122 and closes the second outlet 123. 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 4 heats the water inlet coil 3 and the vaporization chamber 120 through the housing 1. The water in the water inlet coil 3 is heated while flowing and becomes hot water, steam, or a mixture of steam and hot water. The hot water, steam, or a mixture of steam and hot water enters the vaporization chamber 120 from the water outlet end 32 of the water inlet coil 3 through the diversion chamber 121 and the first channel 122 in sequence. The steam in the vaporization chamber 120 is discharged from the first outlet 111. The hot water in the vaporization chamber 120 is heated again to form steam, and then discharged from the first outlet 111 into the steam inlet of the cooking box 400 to provide steam for cooking food for the cooking box 400.

[0075] In the second outlet steam supply mode, the controller 2 opens the second outlet 123 and closes the first channel 122. 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 4 heats the water inlet coil 3 and the vaporization chamber 120 through the housing 1. The water in the water inlet coil 3 is heated while flowing and becomes hot water, steam, or a mixture of steam and hot water. The hot water, steam, or a mixture of steam and hot water is passed into the diversion chamber 121 from the water outlet end 32 of the water inlet coil 3, and is discharged from the second outlet 123 into the first cleaning device 501 of the fan 500 of the smoke exhaust device, providing the first cleaning device 501 with hot water, steam, or a mixture of steam and hot water for cleaning the fan 500.

[0076] Therefore, the integrated stove is only provided with one multi-outlet steam generator 100, which can be switched to provide the steam required for cooking to the cooking box 400 or hot water, steam or a mixture of steam and hot water to the fan 500 of the oil cleaning and smoke exhaust device, thereby simplifying the size of the device and reducing costs.

[0077] Furthermore, in the first outlet steam supply mode of the multi-outlet steam generator 100, the instant heating mode is adopted in the initial stage, that is, the water inlet speed of the water inlet coil 3 is controlled so that the water inlet coil 3 discharges a mixture of steam and water into the vaporization chamber 120 to quickly provide steam. After running for a period of time, a certain amount of water accumulates in the vaporization chamber 120. Subsequently, it is switched to the boiling water mode, and the water inlet to the water inlet coil 3 is stopped. The vaporization chamber 120 is heated by the heating tube 4 through the shell 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 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 4 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.

[0078] Preferably, the heating tube 4 is an electric heating tube.

[0079] Furthermore, the housing 1 includes a bottom shell 12 and a cover body 11 .

[0080] The vaporization chamber 120 and the flow-dividing chamber 121 are both formed on the bottom shell 12 and have openings communicating with the outside of the bottom shell 12. The cover 11 is disposed at the opening of the vaporization chamber 120 to seal the vaporization chamber 120. The controller 2 is disposed at the opening of the flow-dividing chamber 121 to seal the flow-dividing chamber 121.

[0081] Specifically, the first outlet 111 is opened on the cover body 11 .

[0082] The bottom shell 12 is also provided with a drainage channel 125 in fluid communication with the vaporization chamber 120, and the excess water in the vaporization chamber 120 is drained through the drainage channel 125. Preferably, the drainage channel 125 is vertically arranged and extends to the bottom of the heat transfer bottom plate for easy drainage.

[0083] When in use, the multi-outlet steam generator 100 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 scale is washed away by the drainage channel 125 when the waste water is discharged, so as to avoid 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.

[0084] Preferably, the bottom shell 12 and the cover body 11 are connected by screws.

[0085] Specifically, a sealing gasket 13 is sandwiched between the bottom shell 12 and the cover body 11 to seal the gap therebetween.

[0086] More specifically, the bottom shell 12 is an aluminum alloy bottom shell, and the water inlet coil 3 and the heating tube 4 are cast inside the wall of the bottom shell 12 below the vaporization chamber 120 , so that the water inlet coil 3 and the vaporization chamber 120 can be heated by the heating tube 4 through the bottom shell 12 .

[0087] More specifically, the heating tube 4 and the water inlet coil 3 are arranged vertically and fixed inside the wall of the bottom shell 12 to reduce the volume of the device.

[0088] Preferably, a temperature sensor 14 for monitoring the temperature of the bottom shell 12 is disposed outside the bottom wall of the bottom shell 12 to stop heating when the heating tube 4 is dry-burned due to lack of water, thereby preventing the heating tube 4 from being damaged.

[0089] Further, the flow diversion chamber 121 and the controller 2 include the following two configurations:

[0090] Example 1

[0091] The first configuration of the flow diversion chamber 121 and the controller 2 is as follows:

[0092] The flow dividing chamber 121 includes a first valve chamber 1211, a second valve chamber 1212, and a second passage 1214 connecting the first valve chamber 1211 and the second valve chamber 1212. The first valve chamber 1211 is connected to the vaporizing chamber 120 through the first passage 122. The second outlet 123 is connected to the second valve chamber 1212.

[0093] The controller 2 includes a first control valve 21 and a second control valve 22. The first control valve 21 is fixed at the opening of the first valve chamber 1211 to open or close the first passage 122. The second control valve 22 is fixed at the opening of the second valve chamber 1212 to open or close the second outlet 123.

[0094] In the first outlet steam supply mode, the first control valve 21 opens the first passage 122 , the second control valve 22 closes the second outlet 123 , and steam is discharged from the first outlet 111 .

[0095] In the second outlet steam supply mode, the first control valve 21 closes the first passage 122 , and the second control valve 22 opens the second outlet 123 , and hot water, steam, or a mixture of steam and hot water is discharged from the second outlet 123 .

[0096] It can be seen from the above that the first control valve 21 and the second control valve 22 can conveniently switch the opening of the first outlet 111 or the second outlet 123 .

[0097] Specifically, a first blocking block 15 is inserted at the end of the first channel 122 to prevent the hot water, steam, or a mixture of hot water and steam in the diverter cavity 121 from being directly discharged from the bottom shell 12 through the first channel 122. A second blocking block 16 is inserted at the end of the second channel 1214 to prevent the hot water, steam, or a mixture of hot water and steam in the diverter cavity 121 from being directly discharged from the bottom shell 12 through the second channel 1214.

[0098] Specifically, the first control valve 21 includes a first valve body 211 and a first valve core 212. The first valve body 211 is fixed at the opening of the first valve cavity 1211 to close the first valve cavity 1211. A portion of the first valve core 212 is disposed in the first valve cavity 1211, and the first valve core 212 is connected to the first valve body 211 to be telescopically movable relative to the first valve body 211 to open or close the first channel 122.

[0099] The second control valve 22 includes a second valve body 221 and a second valve core 222. The second valve body 221 is fixed at the opening of the second valve cavity 1212 to close the second valve cavity 1212. A portion of the second valve core 222 is disposed in the second valve cavity 1212, and the second valve core 222 is connected to the second valve body 221 to be telescopically movable relative to the second valve body 221 to open or close the second outlet 123.

[0100] The first valve body 211 is used to transmit the driving force for the first valve core 212 to move in a telescopic manner relative to the first valve body 211. The second valve body 221 is used to transmit the driving force for the second valve core 222 to move in a telescopic manner relative to the second valve body 221.

[0101] When the first valve body 211 drives the first valve core 212 to abut against the connecting port of the first valve cavity 1211 and the first channel 122, and the second valve body 221 drives the second valve core 222 away from the connecting port of the second valve cavity 1212 and the second outlet 123, the first channel 122 is closed and the second outlet 123 is opened; when the first valve body 211 drives the first valve core 212 away from the connecting port of the first valve cavity 1211 and the first channel 122, and the second valve body 221 drives the second valve core 222 to abut against the connecting port of the second valve cavity 1212 and the second outlet 123, the second outlet 123 is closed and the first channel 122 is opened.

[0102] Preferably, the diverter cavity 121 further includes a third valve cavity 1213. The second channel 1214 passes through the first valve cavity 1211, the second valve cavity 1212 and the third valve cavity 1213. The bottom shell 12 is further provided with a third outlet 124 connected to the third valve cavity 1213. The controller 2 further includes a third control valve 23. The third control valve 23 is fixed at the opening of the third valve cavity 1213, and is used to open or close the third outlet 124.

[0103] The third outlet 124 is connected to the second cleaning device 402 in the inner cavity of the cooking box 400 .

[0104] The multi-outlet steam generator 100 also includes a third outlet steam supply mode:

[0105] In the third outlet steam supply mode, the first control valve 21 closes the first channel 122, the second control valve 22 closes the second outlet 123, and the third control valve 23 opens the third outlet 124. 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 4 heats the water inlet coil 3 and the vaporization chamber 120 through the housing 1. The water in the water inlet coil 3 is heated while flowing and becomes hot water, steam, or a mixture of steam and hot water. The hot water, steam, or a mixture of steam and hot water passes into the first valve chamber 1211 of the diversion chamber 121 from the water outlet end 32 of the water inlet coil 3, and then enters the second valve chamber 1212 and the third valve chamber 1213 in sequence through the second channel 1214, and is discharged from the third outlet 124 to the second cleaning device 402 in the inner cavity of the cooking box 400, providing the second cleaning device 402 with hot water, steam, or a mixture of steam and hot water for cleaning the cooking box 400.

[0106] The first control valve 21, the second control valve 22 and the third control valve 23 of the multi-outlet steam generator 100 can be conveniently switched to open the first outlet 111, the second outlet 123 or the third outlet 124, so as to conveniently provide steam for cooking food to the cooking box 400, provide steam, hot water or a mixture of steam and hot water for cleaning grease to the fan 500 of the smoke exhaust device, or provide steam, hot water or a mixture of steam and hot water for cleaning grease to the second cleaning device 402 in the inner cavity of the cooking box 400.

[0107] Specifically, the third control valve 23 includes a third valve body 231 and a third valve core 232. The third valve body 231 is fixed at the opening of the third valve cavity 1213 to close the third valve cavity 1213. A portion of the third valve core 232 is disposed in the third valve cavity 1213, and the third valve core 232 is connected to the third valve body 231 to be telescopically movable relative to the third valve body 231 to open or close the third outlet 124.

[0108] The third valve body 231 is used to transmit a driving force for the third valve core 232 to move telescopically relative to the third valve body 231 .

[0109] When the first valve body 211 drives the first valve core 212 to abut against the connecting port of the first valve cavity 1211 and the first channel 122, the second valve body 221 drives the second valve core 222 to abut against the connecting port of the second valve cavity 1212 and the second outlet 123, and the third valve body 231 drives the third valve core 232 away from the connecting port of the third valve cavity 1213 and the third outlet 124, the first channel 122 and the second outlet 123 are closed, and the third outlet 124 is opened; when the third valve body 231 drives the third valve body 231 to abut against the connecting port of the third valve cavity 1213 and the third outlet 124, the third outlet 124 is closed.

[0114] The controller 2 includes a first control valve 21 . The first control valve 21 includes a first valve body 211 and a first valve core 212 .

[0115] The first valve body 211 is fixed at the opening of the diverter cavity 121 to close the diverter cavity 121. A portion of the first valve core 212 is disposed in the diverter cavity 121 and is connected to the first valve body 211 to be telescopically movable relative to the first valve body 211 to open the first channel 122 or the second outlet 123.

[0116] In the first outlet steam supply mode, the first control valve 21 opens the first passage 122 and closes the second outlet 123 .

[0117] In the second outlet steam supply mode, the first control valve 21 closes the first passage 122 and opens the second outlet 123 .

[0118] Specifically, a through channel 126 connecting the diversion cavity 121 and the first channel 122 is further formed on the bottom shell 12 , and the through channel 126 is arranged opposite to the second outlet 123 .

[0119] Part of the first valve core 212 is inserted in the through channel 126 and the diverter chamber 121, and the first valve core 212 is connected to the piston 213, and the piston 213 is located in the diverter chamber 121. When the first valve body 211 drives the first valve core 212 to telescopically move relative to the first valve body 211, the first valve core 212 drives the piston 213 to open the through channel 126 or the second outlet 123.

[0120] When working, when the first valve core 212 drives the piston 213 to abut the connection port between the first valve cavity 1211 and the second outlet 123, the second outlet 123 is closed and the first channel 122 is opened. When the first valve core 212 drives the piston 213 to abut the connection port between the first valve cavity 1211 and the through channel 126, the second outlet 123 is opened and the first channel 122 is closed.

[0121] Specifically, the first control valve 21 is a two-position three-way solenoid valve.

[0122] Preferably, the top of the flow dividing chamber 121 is open. The through passage 126 and the second outlet 123 are disposed at the top and bottom of the first valve chamber 1211 , respectively. The bottom end of the first valve core 212 is connected to the piston 213 .

[0123] In actual operation, when the multi-outlet steam generator 100 is in the first outlet steam supply mode, the first control valve 21 is de-energized, the piston 213 abuts against the connection port of the first valve chamber 1211 and the second outlet 123, the second outlet 123 is closed, and the first channel 122 is opened. The hot water, steam, or a mixture of steam and hot water in the water inlet coil 3 is discharged from the drainage end into the diversion chamber 121, and then enters the vaporization chamber 120 through the through channel 126 and the first channel 122 in sequence, and is discharged from the first outlet 111 to the steam inlet of the cooking box 400 into the steam for cooking food.

[0124] When the multi-outlet steam generator 100 is in the second outlet steam supply mode, the first control valve 21 is energized, the first valve body 211 drives the first valve core 212 to shorten relative to the first valve body 211 until the piston 213 abuts against the connection port of the first valve cavity 1211 and the first channel 122, the second outlet 123 is opened, and the first channel 122 is closed. The hot water, steam, or a mixture of steam and hot water in the water inlet coil 3 is discharged from the drainage end into the diversion cavity 121, and the hot water, steam, or a mixture of steam and hot water for cleaning the fan 500 is discharged from the second outlet 123 into the first cleaning device 501 of the fan 500 of the smoke exhaust device.
