[0001] The present invention relates to the field of cooking devices, and in particular to a steaming and baking machine. Background Art

[0002] The steam-bake combination machine is a composite cooking device that integrates the functions of an oven and a steamer, and has steaming function, baking function, and steam-bake combination function, etc. For example, the steam-bake combination machine structure disclosed in the Chinese utility model patent No. ZL201820707442.3 (authorization announcement No. CN209284910U) and the Chinese utility model patent No. ZL201821449282.3 (authorization announcement No. CN209031991U).

[0003] Existing steam-bake machines have the following two main problems: (1) When using the baking function or the steam-bake combination function, the temperature of the door surface and the handle is high due to the high temperature inside the inner pot, and the user is at risk of being scalded when opening the door. (2) When using the steaming function, especially when the cavity volume is large, the steam generator has a high power and the amount of steam exhausted is large, resulting in steam in the kitchen environment. After the exhaust steam condenses, the condensed water will drip onto the door glass and even onto the cabinet under the machine, resulting in a poor user experience. Summary of the invention

[0004] The first technical problem to be solved by the present invention is to provide a steam-bake combination machine with a small amount of external steam exhaust in view of the prior art.

[0005] The second technical problem to be solved by the present invention is to provide a steam-bake combination machine capable of reducing the temperature of the door body in view of the prior art.

[0006] The technical solution adopted by the present invention to solve at least one of the above technical problems is: a steam-bake machine, including a box body with an opening on the front side and a door body that can cover the opening, the box body is provided with an inner pot, an upper mounting plate and an air guide cover, the upper mounting plate is located above the inner pot and an installation gap is formed therebetween, the air guide cover is arranged on the upper surface of the upper mounting plate to form a first exhaust duct, an exhaust fan is installed at the air inlet end of the first exhaust duct, and it is characterized in that it also includes a second exhaust duct, the above-mentioned door body has a ventilation interlayer, an air guide port is provided on the side wall of the air outlet end of the above-mentioned first exhaust duct, the air inlet port of the above-mentioned second exhaust duct is connected with the above-mentioned air guide port, and the air outlet port is connected with the upper air inlet fluid of the above-mentioned ventilation interlayer, a semiconductor refrigeration plate is arranged in the above-mentioned first exhaust duct, the hot end of the semiconductor refrigeration plate faces the above-mentioned exhaust fan, and the cold end faces the air inlet port of the above-mentioned second exhaust duct.

[0007] Furthermore, the air guide port is provided on the upper mounting plate, the second exhaust air duct is provided in the mounting gap, the semiconductor cooling sheet is vertically provided on the front edge of the air guide port along the airflow direction in the first exhaust air duct, and a guide plate inclined from top to bottom in the airflow direction is provided on the rear edge, and an air guide inlet for guiding the airflow into the second exhaust air duct is formed between the free end edge of the guide plate and the upper end edge of the semiconductor cooling sheet. The air guide inlet can better divert part of the gas in the first exhaust air duct to the second exhaust air duct, and the cold end of the semiconductor cooling sheet can better cool the gas entering the second exhaust air duct.

[0008] In order to better guide the gas in the second exhaust duct into the ventilation interlayer, an air guide seat and an air guide plate are respectively arranged above and below in the installation gap. The air guide plate is buckled on the above-mentioned air guide seat to enclose the above-mentioned second exhaust duct, and also includes a face lining plate and a door seal arranged on the upper end opening of the door body. The above-mentioned face lining plate is provided with an air vent, and the air outlet port of the above-mentioned second exhaust duct is connected with the air vent. The above-mentioned door seal is provided with an air guide hole that is connected with the upper air inlet of the above-mentioned ventilation interlayer, and the air guide hole is connected with the above-mentioned air vent.

[0009] In order to increase the flow rate of the airflow in the second exhaust air duct, the cross section of the second exhaust air duct gradually decreases along the internal airflow direction thereof.

[0010] Furthermore, the air guide seat is a plate member, which includes a vertical portion and a horizontal portion, and the vertical corner of the plate member is opposite to the air guide port, and the air guide plate is tilted downward along the air flow direction. In this way, after the steam entering the second exhaust air duct is condensed, the condensed water can be accumulated on the air guide seat. Since the air guide seat is close to the inner tank, the high temperature of the inner tank can be used to heat the condensed water accumulated on the air guide seat, thereby achieving self-cleaning of the condensed water.

[0011] The steam entering the ventilation interlayer is slowly condensed, and the condensed water flows downward along the inner side of the ventilation interlayer under the action of gravity.

Installing the steam generating system in the installation gap makes the overall structure of the steam-bake machine more compact, the above-mentioned steam generator can supply steam to the inner pot during the cooking process, and can supply steam to the second exhaust air duct, and compared with simple air cooling, the combination of low-temperature steam and cold air can further enhance the cooling effect on the door body.

[0013] Furthermore, along the airflow direction of the first exhaust air duct, the steam inlet is located upstream of the air guide port. In this way, the steam at the steam inlet can be better supplied to the second exhaust air duct, and the hot end of the semiconductor refrigeration chip can reheat the steam entering the first exhaust air duct from the steam inlet to avoid condensation of the steam in the first exhaust air duct. The reheated steam enters the second exhaust air duct through the air guide port under the action of the exhaust fan, and is converted into low-temperature steam after being cooled by the cold end of the semiconductor refrigeration chip to cool the door body.

[0014] Furthermore, an exhaust port is provided on the top wall of the inner tank, and the air inlet of the first exhaust air duct is provided on the upper mounting plate. The exhaust port is connected to the air inlet through a ventilation pipe, and along the air flow direction of the first exhaust air duct, the air inlet is located upstream of the steam inlet. The air outlet at the air inlet of the first exhaust air duct is relatively large, so the air inlet is located upstream of the steam inlet, so that the air outlet at the air inlet can be better mixed with the steam flowing in from the steam inlet, so that the steam is evenly distributed in the mixed gas.

[0015] In order to better prevent the high temperature of the door body from scalding the user, the door body includes an outer door panel located on the outside, the inner side of the outer door panel is provided with the above-mentioned ventilation interlayer, and the outer door panel constitutes one of the side walls of the ventilation interlayer.

[0016] Compared with the prior art, the advantages of the present invention are: a second exhaust duct is provided, which can divert part of the gas discharged from the first exhaust duct, thereby reducing the exhaust volume at the first exhaust duct, that is, reducing the amount of steam discharged externally; in addition, the air outlet port of the second exhaust duct is connected to the ventilation interlayer on the door body, and the semiconductor refrigeration plate can cool the airflow entering the second exhaust duct, and the cooled airflow can actively cool the door body after entering the ventilation interlayer, thereby reducing the temperature of the door body and preventing the door body from being overheated and scalding the user.

[0021] The present invention is further described in detail below with reference to the accompanying drawings.

[0022] like Figures 1 to 4 As shown, a steam-bake combination machine includes a box body 1 with an opening on the front side and a door body 12 that can cover the opening. An inner pot 11, an upper mounting plate 2 and an air guide cover 3 are arranged in the box body 1. The upper mounting plate 2 is located above the inner pot 11 and a mounting gap is formed therebetween. The air guide cover 3 is covered on the upper surface of the upper mounting plate 2 to form a first exhaust air duct 30. An exhaust fan 31 is installed at the air inlet end of the first exhaust air duct 30. The above-mentioned door body 12 includes an outer door panel 121, a middle door panel 122 and an inner door panel 123 from the outside to the inside. In this embodiment, each door panel is a door glass, and a ventilation interlayer 120 is formed between the outer door panel 121 and the middle door panel 122. The ventilation interlayer 120 has an upper air inlet 1201 and a lower air outlet 1202. A door seal 124 is arranged above the upper door body 12, and an air guide hole 1241 is arranged on the door seal 124. The air guide hole 1241 is communicated with the upper air inlet 1201 of the above-mentioned ventilation interlayer 120.

[0023] Furthermore, the first exhaust duct 30 is provided with an air guide port 21 on the upper mounting plate 2 at the air outlet end thereof, and further includes a second exhaust duct 4, the air inlet port 401 of the second exhaust duct 4 is in communication with the air guide port 21, and the air outlet port 402 is in fluid communication with the upper air inlet port 1201 of the ventilation interlayer 120. In this embodiment, an air vent 131 is provided on the surface lining plate 13 of the box body 1, the air outlet port 402 of the second exhaust duct 4 is in communication with the air vent 131, and the air guide hole 1241 is in communication with the air vent 131, so that the gas in the second exhaust duct 4 can be introduced into the ventilation interlayer 120. The first exhaust duct 30 is provided with a semiconductor cooling plate 7, the hot end 71 of the semiconductor cooling plate 7 faces the exhaust fan 31, and the cold end 72 faces the air inlet port 402 of the second exhaust duct 4. By providing a second exhaust duct 4, the second exhaust duct 4 can divert part of the gas discharged from the first exhaust duct 30, thereby reducing the exhaust volume at the first exhaust duct 30. In addition, the air outlet port 402 of the second exhaust duct 4 is communicated with the ventilation interlayer 120 on the door body 12, and the semiconductor refrigeration plate 7 can cool the airflow entering the second exhaust duct 4. The cooled airflow can actively cool the door body 12 after entering the ventilation interlayer 120, thereby reducing the temperature of the door body 12 and preventing the door body 12 from being too hot and scalding the user.

[0024] Furthermore, the steam entering the ventilation interlayer 120 is slowly condensed, and the condensed water flows downward along the inner side of the ventilation interlayer 120 under the action of gravity. In order to prevent the condensed water from dripping under the door body 12 and affecting the user's experience, a condensed water tank 5 is provided in the lower air outlet 1202 of the ventilation interlayer 120, and the condensed water dripping from top to bottom is received by the condensed water tank 5.

[0025] In this embodiment, the second exhaust duct 4 is arranged in the installation gap, the semiconductor cooling sheet 7 is vertically arranged on the front edge of the air guide port 21 along the airflow direction in the first exhaust duct 30, and a guide plate 9 tilted downward along the airflow direction is arranged on the rear edge, and an air guide inlet 91 for guiding the airflow into the second exhaust duct 4 is formed between the free end edge of the guide plate 9 and the upper end edge of the semiconductor cooling sheet 7. The air guide inlet 91 can better guide part of the gas in the first exhaust duct 30 to the second exhaust duct 4, and the cold end 72 of the semiconductor cooling sheet 7 can better cool the gas entering the second exhaust duct 4. Specifically, in the present embodiment, an air guide seat 42 and an air guide plate 41 are respectively provided in the installation gap, and the air guide plate 41 is buckled on the above-mentioned air guide seat 42 to enclose the above-mentioned second exhaust duct 4, and also includes a surface lining plate 13 and a door seal 124 provided on the upper end opening of the door body 12, and the above-mentioned surface lining plate 13 is provided with an air vent 131, and the air outlet port 402 of the above-mentioned second exhaust duct 4 is connected with the air vent 131, and the above-mentioned door seal 124 is provided with an air guide hole 1241 which is connected with the upper air inlet 1201 of the above-mentioned ventilation interlayer 120, and the air guide hole 1241 is connected with the above-mentioned air vent 131. Preferably, the cross section of the second exhaust duct 4 gradually decreases along the direction of the internal air flow, thereby increasing the flow rate of the air flow in the second exhaust duct 4. Specifically, the air guide seat 42 is a plate, which includes a vertical portion 421 and a horizontal portion 422, and the vertical angle of the plate is opposite to the above-mentioned air guide port 21, and the above-mentioned air guide plate 41 is inclined downward along the air flow direction. In this way, after the steam entering the second exhaust duct 4 is condensed, the condensed water can be accumulated on the air guide seat 42. Since the air guide seat 42 is close to the inner tank 11, the high temperature of the inner tank 11 can be used to heat the condensed water accumulated on the air guide seat 42, thereby achieving self-cleaning of the condensed water.

[0026] In this embodiment, the installation gap is further provided with a steam generating system 6, which includes a steam generator 61, a first steam outlet pipe 62, a second steam outlet pipe 63, a first steam valve 64 and a second steam valve 65. The steam generator 61 has a first steam outlet 611 and a second steam outlet 612. The upper mounting plate 2 is provided with a steam inlet 22 located in the first exhaust air duct 30. The top wall of the inner tank 11 is provided with a steam inlet 112. Both ends of the first steam outlet pipe 62 are respectively connected to the first steam outlet 611 and the steam inlet 22, while both ends of the second steam outlet pipe 63 are respectively connected to the second steam outlet 612 and the steam inlet 112. The first steam valve 64 and the second steam valve 65 are respectively provided on the first steam outlet pipe 62 and the second steam outlet pipe 63. Installing the steam generating system 6 in the installation gap makes the overall structure of the steam-bake machine more compact. The steam generator 61 can supply steam to the inner pot 11 during the cooking process, and can also supply steam to the second exhaust duct 4. Compared with simple air cooling, the combination of low-temperature steam and cold air can further enhance the cooling effect on the door body 12.

[0027] Furthermore, along the airflow direction of the first exhaust air duct 30, the steam inlet 22 is located upstream of the air guide port 21. In this way, the steam at the steam inlet 22 can be better supplied to the second exhaust air duct 4, and the hot end 72 of the semiconductor refrigeration sheet 7 can reheat the steam entering the first exhaust air duct 30 from the steam inlet 22 to prevent the steam from condensing in the first exhaust air duct 30. The reheated steam enters the second exhaust air duct 4 through the air guide port 91 under the action of the exhaust fan 31, and is converted into low-temperature steam after being cooled by the cold end 72 of the semiconductor refrigeration sheet 7 to cool the door body 12. Along the airflow direction of the first exhaust air duct 30, the steam inlet 22 is located upstream of the air guide port 21. In this way, the steam at the steam inlet 22 can be better supplied to the second exhaust duct 4, and the hot end 71 of the semiconductor refrigeration plate 7 can reheat the steam entering the first exhaust duct 30 from the steam inlet 22 to prevent the steam from condensing in the first exhaust duct 30. The reheated steam enters the second exhaust duct 4 through the air guide inlet 91 under the action of the exhaust fan 31, and is converted into low-temperature steam after being cooled by the cold end 72 of the semiconductor refrigeration plate 7 to cool the door body 12.

[0028] Furthermore, an exhaust port 111 is provided on the top wall of the inner tank 11, and the air inlet 23 of the first exhaust air duct 30 is provided on the upper mounting plate 2. The exhaust port 111 is connected to the air inlet 23 through the ventilation pipe 8, and along the air flow direction of the first exhaust air duct 30, the air inlet 23 is located upstream of the steam inlet 22. The air flow at the air inlet of the first exhaust air duct 30 is relatively large, so the air inlet 23 is located upstream of the steam inlet 22, so that the air flow at the air inlet 23 can be better mixed with the steam flowing in from the steam inlet 22, so that the steam is evenly distributed in the mixed gas.

[0029] The working mode of the steam-bake combination machine of the present invention is as follows:

[0030] 1. Baking function:

[0031] The first steam valve 64 is closed, the steam generator 61 and the first steam valve 64 are opened, the semiconductor cooling plate 7 starts to work, the steam generated by the steam generator 61 enters the first exhaust air duct 30 through the second steam valve 65, and the hot air in the inner tank 11 enters the first exhaust air duct 30 through the exhaust port 111 and the air inlet 23 of the first exhaust air duct 30 in turn. Under the action of the exhaust fan 31, the high-temperature steam and hot air are cooled for the first time, and then blown to the semiconductor cooling plate 7, and cooled for the second time through the cold end 72 of the semiconductor cooling plate 7, and the temperature of the steam and hot air is further reduced, and converted into low-temperature steam and cold air to enter the second exhaust air duct 4. The low-temperature steam and cold air in the second exhaust air duct 4 enter the ventilation interlayer 120 of the door body 12 through the air vents 131 of the face lining plate 13 and the air guide holes 1241 on the door seal 124 in turn. After the low-temperature steam and cold air are mixed with the heat in the door body 12, they are discharged into the atmosphere through the lower air outlet 1202 below the door body 12, thereby cooling the door body 12. Most of the condensed water generated during the cooling process of the door body 12 will drip into the condensed water tank 5 below the door body 12 under the action of its own gravity, and a small amount of condensed water will be adsorbed on the inner surfaces of the outer and middle door panels 121 and 122. A certain time before the end of the baking function, the steam generator 61 and the second steam valve 65 are closed, and no more condensed water is formed in the door body 12. At this time, the heat radiated from the inner tank 11 to the door body 12 will further evaporate the condensed water remaining on the surfaces of the outer door panel 121 and the middle door panel 122.

[0032] 2. Steaming function:

[0033] The steam generator 61 and the first steam valve 64 are opened, the second steam valve 65 is closed, the semiconductor refrigeration plate 7 starts to work, the steam generated by the steam generator 61 enters the inner tank 11 through the first steam valve 64, and the excess steam in the inner tank 11 enters the first exhaust duct 30 through the exhaust port 111. Under the action of the exhaust fan 31, the high-temperature steam is cooled for the first time and flows to the junction of the first exhaust duct 30 and the second exhaust duct 4. Part of the steam is directly discharged into the atmosphere through the first exhaust duct 30, and part of the steam is cooled for the second time through the semiconductor refrigeration plate 7 to form low-temperature steam and enters the second exhaust duct 4. The low-temperature steam entering the second exhaust duct 4 successively enters the ventilation interlayer 120 of the door body 12 through the air permeable port 131 on the face lining plate 13 and the air guide hole 1241 of the door seal 124. After the low-temperature steam and cold air are mixed with the heat in the door body 12, they are discharged into the atmosphere through the lower air outlet 1202 under the door body 12. On the one hand, the door body 12 is cooled, and on the other hand, the amount of steam discharged externally is reduced, thereby improving the user experience.

[0034] 3. Steaming and baking combination function:

[0035] The steam generator 61 and the first steam valve 64 are opened, the second steam valve 65 is closed, and the semiconductor refrigeration plate 7 starts to work. The steam generated by the steam generator 61 enters the inner tank 11 through the first steam valve 64, and the excess steam and hot air enter the first exhaust duct 30 through the exhaust port 111, and are cooled twice by the exhaust fan 31 and the semiconductor refrigeration plate 7 in turn to form low-temperature steam and cold air and enter the second exhaust duct 4, and finally enter the ventilation interlayer 120 of the door body 12 to cool the door body 12.
