[0001] The present application relates to the field of cooking devices, in particular to a cooking all-in-one machine with steaming and baking functions. BACKGROUND

[0002] The cooking all-in-one machine is a device that combines a cooking device with a stove, a range hood or a disinfection cabinet, etc., wherein the cooking device with steaming and baking functions has both steaming and baking functions, and both functions are performed in the same inner container. For example, Chinese invention patent No. CN202210876949.2 (publication No. CN115164251A), Chinese utility model patent No. ZL 202221515622.4 (authorization announcement No. CN217610636U), etc.

[0003] Further, the inner container of the above-mentioned cooking device generally has only one fixed-size exhaust port on the top wall, which can cause the following problems:

[0004] When the steaming function is performed, the exhaust speed of the inner container is too fast, which affects the heating effect and the endurance of the water tank, and also makes the kitchen environment too humid; when the baking function is performed, the exhaust speed of the inner container is too slow, which causes the inner container to have too much humidity and affects the baking effect, especially when baking dishes that have high requirements for moisture removal performance, such as bean paste, dried fruits and vegetables, lemon slices, cakes, etc. SUMMARY

[0005] The first technical problem to be solved by the present application is to provide a cooking device with steaming and baking functions and good exhaust effect.

[0007] The third technical problem to be solved by the present application is to provide a cooking all-in-one machine with the above-mentioned cooking device.

[0008] The technical solution adopted by the present application to solve the above-mentioned at least one technical problem is: a cooking device with steaming and baking functions, comprising an inner container, one side of the inner container is provided with a hot air blower, and the side of the inner cavity of the inner container is provided with a hot air baffle, the hot air baffle and the corresponding side wall of the inner container form a hot air chamber, the impeller of the above-mentioned hot air blower is located in the hot air chamber, and a heating pipe is arranged on the outer periphery of the impeller, characterized in that an exhaust port is formed on the inner container, the exhaust port is located in the above-mentioned hot air chamber and on one side of the impeller of the above-mentioned hot air blower, a wind blocking structure is arranged on the inner port of the above-mentioned exhaust port along the length direction of the upper edge of the exhaust port, the wind blocking structure is perpendicular to the inner side surface of the inner container at the position where it is located and is located on the side of the exhaust port away from the impeller, and the height of the wind blocking structure is adjustable.

[0009] Further, the wind blocking structure comprises:

[0010] a receiving groove arranged on the back plate of the inner container and extending along the length direction of the rim of the exhaust port;

[0011] a baffle plate embedded in the receiving groove along the length direction of the receiving groove;

[0012] a first driving motor arranged on the back surface of the inner container and used for driving the baffle plate to move back and forth relative to the receiving groove. The height of the wind blocking structure can be adjusted by moving the baffle plate back and forth relative to the receiving groove.

[0013] Further, the wind blocking structure further comprises a base fixed on the inner surface of the back plate of the inner container, the base extending along the length direction of the rim of the exhaust port, and the base being hollow and opening forward to form the receiving groove. In this way, the sealing of the inner container can be ensured, and the baffle plate can be arranged stably.

[0014] Further, a first mounting hole is arranged on the rear groove wall of the receiving groove of the base, and a second mounting hole is arranged on the back plate of the inner container and opposite to the first mounting hole in the front-rear direction,

[0015] the wind blocking structure further comprises a transmission rod extending in the front-rear direction, the front end of the transmission rod penetrating the second mounting hole and the first mounting hole in sequence and being fixed with the rear end of the baffle plate, and the rear end being connected with the first output shaft of the first driving motor and being movable back and forth relative to the hole rims of the mounting holes. In this way, the second mounting hole arranged on the back plate of the inner container is used for penetrating the transmission rod, and the first driving motor outside the inner container is used for driving the baffle plate, so that the influence on the structure of the inner container is avoided to the greatest extent.

[0016] Further, a first external thread is arranged on the outer surface of the first output shaft of the first driving motor, and the rear end of the transmission rod is provided with a transmission screw sleeve, the transmission screw sleeve being threadedly connected with the first output shaft of the first driving motor to form a first threaded transmission pair.

In this way, the second mounting hole can be sealed, the gas leakage at the second mounting hole is avoided, and the sealing of the inner container is ensured better.

[0018] Further, the central angle of the cross section of the baffle is greater than or equal to 180°. Thus, the wind blocking structure can better block and guide the air flow flowing to the exhaust port, so that the air flow can be smoothly discharged from the exhaust port.

[0019] Further, the included angle between the line connecting the two ends of the baffle and the vertical direction is 30°-45°. Thus, the wind blocking structure can better capture the air flow flowing to the exhaust port and better guide it to the exhaust port.

[0020] Further, the impeller of the hot air machine includes a hub vertically arranged in the left-right direction and blades arranged around the outer periphery of the hub. The front-rear height of the base is not greater than the distance between the front surface of the hub and the front surface of the inner container back plate, and the sum of the front-rear height of the base and the front-rear height of the baffle is greater than the distance between the front surface of the hub and the front surface of the inner container back plate. In this way, the exhaust speed of the inner container can be reduced to the greatest extent during steaming, and the steaming effect can be better ensured.

[0021] Further, the rotational speed of the hot air machine is adjustable. The rotational speed adjustment of the hot air machine in combination with the height adjustment of the wind blocking structure can better control the exhaust speed of the inner container.

[0022] Further, the inner container is further provided with an openable and closable air inlet. During the baking function, air is blown into the inner container through the air inlet, which can further improve the dehumidifying effect.

[0023] Further, the air inlet is arranged on the back plate of the inner container and located in the hot air chamber, and the air inlet is located on one side of the impeller of the hot air machine. The air from the outside first enters the hot air chamber, and then enters the inner cavity of the inner container after being preheated, thereby avoiding the influence of cold air directly entering the inner cavity of the inner container on the uniformity of the temperature field.

[0024] Further, a blower is further arranged outside the inner container, the air inlet includes a first air inlet in fluid communication with the air outlet of the blower and a second air inlet in fluid communication with the air outlet port of the hot air source. In this way, the first air inlet uses the blower to efficiently blow air from the outside, and the second air inlet can directly blow hot air to avoid the influence of the low internal pressure of the inner container on the dehumidifying effect.

[0025] Further, the exhaust port of the inner container is connected with a first air pipe in communication with the outside, the first air inlet of the inner container is connected with the air outlet of the blower through a second air pipe, and the second air inlet is connected with the air outlet port of the hot air source through a third air pipe. Furthermore, control valves for controlling the flow rate of air flow are arranged on the first air pipe, the second air pipe and the third air pipe, respectively. In this way, the control valves can realize the opening and closing control and the flow rate control of the exhaust port, the first air inlet and the second air inlet.

[0026] To further solve the third technical problem, the technical solution adopted is: a cooking integrated machine, characterized in that it comprises the cooking device with the steaming and baking functions as described above and a cooking range arranged above the cooking device.

[0027] Compared with the prior art, the advantages of the present application are that the wind blocking structure is arranged in the present application, and the height of the wind blocking structure is adjustable. When the height of the wind blocking structure is low, the blocking effect on the airflow is small, and the air pressure at the exhaust port is relatively small, and the exhaust speed is relatively slow. When the height of the wind blocking structure is high, the blocking effect on the airflow is large, and the air pressure at the exhaust port is relatively large, and the exhaust speed is relatively fast. Thus, by adjusting the height of the wind blocking structure, the exhaust speed of the exhaust port can be adjusted. When the steaming function is performed, the height of the wind blocking structure is adjusted to be low, and the exhaust speed of the inner container is slow, so that the exhaust speed of the steam in the inner container can be reduced, and the high-temperature steam can fully exchange heat with the food, improve the heating efficiency, ensure the steaming effect, and prolong the endurance of the water tank. When the baking function is performed, the height of the wind blocking structure is adjusted to be high, and the exhaust speed of the inner container is fast, so that the humidity inside the inner container is not too large, and the baking effect is ensured.

In addition, the features defined as "first", "second" can explicitly or implicitly include one or more of the features.

[0044] As Figures 1 to 5 , Figure 13 and Figure 14As shown, a cooking all-in-one machine comprises a cooking device with steaming and baking functions and a stove 2 arranged above the cooking device 1. The cooking device 1 comprises an inner container 10, a hot air blower 23 is arranged on the back plate of the inner container 10, and a hot air baffle 3 is arranged on the rear side of the inner cavity of the inner container 10, which forms a hot air chamber 30 together with the back plate of the inner container 10. The impeller 231 of the hot air blower 23 is located in the hot air chamber 30, and the outer periphery of the impeller 231 is provided with a heating pipe 22. The back plate of the inner container 10 is provided with an exhaust port 101, which is located in the hot air chamber 30 and on one side of the impeller 231 of the hot air blower 23. The inner port of the exhaust port 101 is provided with a wind blocking structure 4 along the length direction of the port edge of the exhaust port 101, which is perpendicular to the inner surface of the back plate of the inner container 10 and located on the side of the exhaust port 101 away from the impeller 231, and the front and back heights of the wind blocking structure 4 are adjustable. In the embodiment, the heating pipe 22 is circular in shape, and the exhaust port 101 is arranged outside the heating pipe 22.

[0045] In the present application, the wind blocking structure 4 is provided, and the front and back heights of the wind blocking structure 4 are adjustable. When the height of the wind blocking structure 4 is low, the resistance to airflow is small, the air pressure at the exhaust port 101 is relatively small, and the exhaust speed is relatively slow; when the height of the wind blocking structure 4 is high, the resistance to airflow is large, the air pressure at the exhaust port 101 is relatively large, and the exhaust speed is relatively fast, so that the exhaust speed of the exhaust port 101 can be adjusted by adjusting the height of the wind blocking structure 4. In this way, when the steaming function is used, the height of the wind blocking structure 4 is adjusted to be low, the exhaust speed of the inner container 10 is slow, so that the exhaust speed of the steam in the inner container 10 can be reduced, and the high-temperature steam can fully exchange heat with the food, improve the heating efficiency, ensure the steaming effect, and prolong the endurance of the water tank; when the baking function is used, the height of the wind blocking structure 4 is adjusted to be high, the exhaust speed of the inner container 10 is fast, the humidity in the inner container 10 is prevented from being too large, and the baking effect is ensured.

[0046] Specifically, the wind blocking structure 4 in the embodiment comprises a receiving groove 410 arranged on the back plate of the inner container 10 and extending along the length direction of the rim of the exhaust port 101; a baffle 42 embedded in the receiving groove 410 along the length direction of the receiving groove 410; and a first driving motor 43 arranged on the back surface of the inner container 10 and used to drive the baffle 42 to move back and forth relative to the receiving groove 410. In this way, the height of the wind blocking structure 4 can be adjusted by moving the baffle 42 back and forth relative to the receiving groove 410. Preferably, the wind blocking structure 4 further comprises a base 41 fixed to the inner surface of the back plate of the inner container 10, the base 41 extending along the length direction of the rim of the exhaust port 101, and the base 41 being hollow and opening forward to form the receiving groove 410. In this way, the groove can be avoided to be directly opened on the back plate of the inner container 10, so as to affect the sealing of the inner container 10, and the baffle 42 can be better and stably arranged.

[0047] Further, as shown in Figure 5 the base 41 is provided with a first mounting hole 411 on the rear groove wall of the receiving groove 410, and the back plate of the inner container 10 is provided with a second mounting hole 104 opposite to the first mounting hole 411. The wind blocking structure 4 further comprises a transmission rod 421 extending back and forth, the front end of the transmission rod 421 penetrating the second mounting hole 104 and the first mounting hole 411 in sequence and being fixed to the rear end of the baffle 42, and the rear end being connected with a first output shaft 431 of the first driving motor 43 and being able to move back and forth relative to the rim of the mounting hole, as shown in Figure 5 In this way, the second mounting hole 104 for the transmission rod 421 to penetrate is only arranged on the back plate of the inner container 10, so that the first driving motor 43 located outside the inner container 10 can drive the baffle 42, and the influence on the structure of the inner container 10 is minimized.

[0048] Further, the outer surface of the first output shaft 431 of the first driving motor 43 is provided with a first external thread, and the rear end of the transmission rod 421 is provided with a transmission screw sleeve 422, the transmission screw sleeve 422 being threadedly connected with the first output shaft 431 of the first driving motor 43 to form a first threaded transmission pair. In this way, the first driving motor 43 can smoothly drive the transmission rod 421 when rotating, and further drive the baffle 42 to move back and forth. Preferably, a first motor seat 432 for mounting the first driving motor 43 is arranged on the back surface of the inner container 10.

[0049] Preferably, a front-to-rear extending mounting sleeve 44 is fixed on the back of the inner container 10 at the second mounting hole 104, and an end cover 441 is provided at the free end of the mounting sleeve 44. The transmission rod 421 passes through the end cover 441 and is arranged in the mounting sleeve 44 along the central axis of the mounting sleeve 44, and a sealing sleeve 442 is arranged on the transmission rod 421 and fills the space between the mounting sleeve 44 and the end cover 441. In this way, the second mounting hole 104 is sealed, and gas leakage at the second mounting hole 104 is avoided, thereby better ensuring the sealing of the inner container 10.

[0050] In addition, preferably, the central angle of the cross section of the baffle 42 is greater than or equal to 180°, so that the wind blocking structure 4 can better block and guide the airflow flowing to the exhaust port 101, and the airflow can be smoothly discharged from the exhaust port 101. The angle between the line connecting the two ends of the baffle 42 and the vertical direction is 30°-45°, so that the wind blocking structure 4 can better capture the airflow flowing to the exhaust port 101 and better guide it to the exhaust port 101. The impeller 231 of the hot air machine 23 includes a hub 2311 arranged vertically in the left-right direction and blades 2312 arranged around the outer periphery of the hub 2311. The front-to-rear height of the base 41 is not greater than the distance between the front surface of the hub 2311 and the front surface of the back plate of the inner container 10, and the sum of the front-to-rear height of the base 41 and the front-to-rear height of the baffle 42 is greater than the distance between the front surface of the hub 2311 and the front surface of the back plate of the inner container 10. In this way, the exhaust speed of the inner container 10 can be reduced to the greatest extent during steaming, and the steaming effect can be better ensured. In addition, in the present embodiment, the speed of the hot air machine 23 is adjustable, and the exhaust speed of the inner container 10 can be better controlled by combining the speed adjustment of the hot air machine 23 with the height adjustment of the wind blocking structure 4.

[0051] Further, an openable and closable air inlet is further provided on the inner container 10, so that air is blown into the inner container 10 through the air inlet during the roasting function, thereby further improving the dehumidification effect. Preferably, the air inlet is provided on the back plate of the inner container 10 and located in the hot air chamber 30, and the air inlet is located on one side of the impeller 231 of the hot air machine 23. The air blown from the outside first enters the hot air chamber 30, is preheated, and then enters the inner cavity of the inner container 10, thereby avoiding the direct entry of cold air into the inner cavity of the inner container 10 and affecting the uniformity of the temperature field.

[0052] Further, the air inlet includes a first air inlet 102 in fluid communication with the air outlet of the air blower 5 and a second air inlet 103 in fluid communication with the air outlet of the hot air source. In this way, the first air inlet 102 can efficiently draw in ambient air by the air blower 5, while the second air inlet 103 can avoid the internal pressure of the inner container 10 from being too low to affect the dehumidification effect by directly drawing in hot air. In the present embodiment, the cooking appliance 2 includes a cooking shell 20 including a bottom disc 201 with an upper opening and a panel 202 covering the opening of the bottom disc 201, and a heat dissipation channel 21 extending front to back is arranged in the cooking shell 20, and an exhaust window 2021 is arranged at the back of the panel 202. The front port of the heat dissipation channel 21 is in communication with the ambient, and the rear port is in fluid communication with the exhaust window 2021, so that the heat dissipation channel 21 can dissipate heat for electrical elements (such as power boards, etc.) inside the cooking appliance 2. Preferably, an exhaust box 22 is arranged on the lower surface of the panel 202 at the exhaust window 2021, and the front face of the exhaust box 22 has a first air inlet 221, and the bottom has a second air inlet 222 and a first air outlet 223, wherein the rear port of the heat dissipation channel 21 is in communication with the first air inlet 221 of the exhaust box 22. At the same time, the exhaust port 101 of the inner container 10 is in communication with the second air inlet 222 of the exhaust box 22 through the first air pipe 61, so that the gas in the inner container 10 can be discharged into the exhaust box 22 through the second air inlet 222, and then discharged to the outside through the exhaust window 2021 on the panel 202. In addition, in the present embodiment, the hot air source is the heat dissipation channel 21, the air outlet of the hot air source is the rear port of the heat dissipation channel 21, and the second air inlet 103 is in communication with the second air inlet 222 of the exhaust box 22 through the third air pipe 63. In addition, the first air inlet 102 is in communication with the air outlet of the air blower 5 through the second air pipe 62. In the present embodiment, the exhaust port 101 and the first air inlet 102 are arranged on the left side of the impeller 231 of the hot air machine 23, and the second air inlet 103 is arranged on the back side of the impeller 231, and the height of the exhaust port 101 is higher than that of the first air inlet 102, and the height of the second air inlet 103 is slightly higher than that of the exhaust port 101.

[0053] Furthermore, control valves 7 for controlling the airflow rate are respectively installed on the first air pipe 61, the second air pipe 62, and the third air pipe 63. These control valves 7 allow for the opening and closing of the exhaust port 101, the first air inlet 102, and the second air inlet 103, as well as the control of the airflow rate. Specifically, in steam mode (when the hot air blower 23 is not turned on or is running at very low speed), the control valves 7 on the first air pipe 61 and the third air pipe 63 are closed, while the control valve 7 on the second air pipe 62 is open. At different stages of cooking, the flow rate of the second air pipe 62 is adjusted by the control valves 7, thereby regulating the steam exhaust speed from the inner pot 10. In the normal baking mode (hot air blower 23 rotating at low speed), the control valves 7 on the first gas pipe 61 and the third gas pipe 63 are closed, while the control valve 7 on the second gas pipe 62 is open. During the preheating stage, the control valve 7 on the second gas pipe 62 is only partially open (i.e., the flow rate of the second gas pipe 62 is low). During the baking stage, the control valve 7 is opened to its maximum to ensure smooth dehumidification of the inner cavity 10 and guarantee the baking effect. Furthermore, when baking dishes that require high dehumidification (hot air blower 23 rotating at low speed), the control valve 7 on the first gas pipe 61 is open, the control valve 7 on the second gas pipe 62 is opened to its maximum, and the control valve 7 on the third gas pipe 63 is closed. By blowing in hot air, the dehumidification effect is improved. Furthermore, when baking dishes that require high humidity control (such as baking melt-in-your-mouth beans, dried fruits and vegetables, lemon slices, etc.), the hot air blower 23 rotates at its maximum speed, the control valve 7 on the first air pipe 61 and the control valve 7 on the second air pipe 62 are both opened to their maximum, the control valve 7 on the third air pipe 63 is opened, and the opening size is adjusted according to the humidity change in the inner liner 10.

[0054] The control valve 7 in this invention can adopt an existing structure or the structure of this embodiment. Specifically, in this embodiment, as shown... Figures 6 to 12 As shown, each of the aforementioned control valves 7 includes a cylindrical valve body 71, a valve core 72, and a valve shaft 73. One end of the valve body 71 is connected to the corresponding port of the corresponding air pipe, while the other end is connected to the exhaust port 101 of the inner liner 10, the blower outlet of the blower 5, or the outlet port of the hot air source. The valve core 72 is spaced within the valve body 71 along its cross-sectional direction. The valve core 72 is a plate and includes a semi-circular first valve plate 721 and a second valve plate 722. The valve shaft 73 is arranged along the axis of symmetry of the first valve plate 721 and the second valve plate 722, and both the first valve plate 721 and the second valve plate 722 can rotate around the valve shaft 73. Thus, the opening and closing of the control valve 7 and the control flow rate can be controlled by the rotation of the first valve plate 721 and the second valve plate 722. Specifically, when the first valve plate 721 and the second valve plate 722 are joined together to form a circle along the cross-section of the valve body 71, the control valve 7 is closed, and when the first valve plate 721 and the second valve plate 722 overlap, the control valve is fully open.

[0055] Further, each of the control valves further comprises a driving mechanism for driving the first valve plate 721 and the second valve plate 722 to rotate around the valve shaft 73, respectively. The valve shaft 73 comprises a shaft body 731 fixed to the straight side of the first valve plate 721 and a shaft sleeve 732 fixed to the straight side of the second valve plate 722 and sleeved on the shaft body 731. Preferably, in the embodiment, a first limiting ring 7311 and a second limiting ring 7312 are protruded and spaced apart along the length direction of the outer surface of the shaft body 731, and the shaft sleeve 732 comprises a first sleeve body 7321, a second sleeve body 7322 and a third sleeve body 7323 spaced apart along the length direction of the shaft sleeve 732.
