Description

TECHNICAL FIELD

[0001] The present application relates to the field of household appliances, in particular to an integrated cooking device. BACKGROUND

[0002] The integrated cooking device (for example, integrated stove, etc.) is a household appliance integrating cooking device and stove, etc., for example, Chinese patent No. ZL201910362195.7 (authorized publication No. CN111853876B) "Integrated Stove with Cooking Device", Chinese patent No. ZL202110734434.4 (authorized publication No. CN113531600B) "Integrated Cooking Device", etc.

[0003] However, with the increasing degree of integration and the increasing degree of intelligence, the amount of electronic components used inside the device is also increasing, so heat dissipation is one of the problems that need to be solved for the integrated cooking device at present. In addition, when multiple dishes are continuously cooked, the inner container of the cooking device needs to be naturally cooled before the next dish can be cooked, which takes too long to wait, especially when the inner container temperature is high after the last cooking, which affects the user's experience.

[0004] Further, the high humidity inside the inner container of the cooking device during the baking process will affect the baking effect, especially when baking food with high water content. In the prior art, the humidity in the inner container is generally removed by blowing, for example, Chinese patent No. CN202210403553.6 (publication No. CN114893793A) "Cooking Device and Integrated Stove with Cooking Device", etc. However, the blowing method needs to add a blowing device (generally a blower, etc.) outside the inner container, which leads to the complication of the structure of the cooking device and increases the cost. At the same time, the use environment of the integrated cooking device is complex (generally the kitchen environment), and directly blowing outside air into the inner container will affect the cooking safety due to impurities contained in the air. SUMMARY

[0005] The first technical problem to be solved by the present application is to provide an integrated cooking device with simple structure and air guiding and humidity removing functions.

[0006] The second technical problem to be solved by the present application is to provide an integrated cooking device with air guiding and humidity removing functions and high cooking safety.

[0007] The third technical problem to be solved by the present application is to provide an integrated cooking device with air guiding and humidity removing functions, high cooking safety and long service life.

[0011] Further, the cooking device further comprises a cooling device for cooling the gas in the air guiding cavity. By cooling the gas in the air guiding cavity, the gas introduced into the inner container is low-temperature gas, so that the internal temperature of the inner container can be quickly reduced, thereby effectively shortening the interval waiting time of the user when continuously cooking multiple dishes, in addition, by appropriately reducing the internal temperature of the inner container at the end of cooking, the user can also be prevented from being scalded by the high internal temperature of the inner container (on the basis of preventing the temperature of the cooked food from being quickly reduced).

[0016] In the second state, the shielding member is staggered with the first air outlet to open the first air outlet, and the trigger member is separated from the control part of the cooling device, so the cooling device is not working; at this time, in the air induction and moisture removal state, the clean gas treated by purification is supplemented into the inner container through the air inlet, so as to realize the air induction and strong removal of the moisture in the inner container.

[0026] Further, the hot air machine is vertically installed on the top wall of the inner container, the motor of the hot air machine is located above the inner container, and the output shaft of the motor penetrates into the inner container so that the fan blade is installed on the inner top surface of the inner container, the air guide cavity is arranged on the top wall of the inner container, and a purification tank opposite to the air guide cavity is arranged above the inner container, the inner cavity of the purification tank forms the purification cavity, and each first air outlet is arranged on the bottom wall of the purification tank, and the bottom surface of the purification tank is spaced apart from the air guide cavity in the up-down direction, and each air guide pipe is vertically connected between the bottom of the purification tank and the air guide cavity.

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

[0049] As Figures 1 to 13 shown, an integrated cooking device includes a cooking device 1 and a stove 2 arranged above the cooking device 1. Wherein the above-mentioned cooking device 1 includes an inner container 10 and a hot air machine 3 mounted on the inner container 10, the fan blade 31 of the hot air machine 3 is located in the inner container 10. The above-mentioned stove 2 includes an upper open bottom disc 21 and a panel 22 covering the opening of the bottom disc 21, the rear side of the panel 22 is provided with an exhaust window 221, and the lower surface of the panel 22 is provided with an exhaust box 25 at the exhaust window 221, the bottom wall of the exhaust box 25 is provided with an air inlet 251, the air inlet 251 is connected with the exhaust port (not shown) of the inner container 10 through the exhaust pipe 12, so as to realize the centralized exhaust of the cooking device 1 from bottom to top. In the embodiment, the exhaust cover plate 2211 is arranged on the exhaust window 221.

[0050] Further, as Figure 4 shown, the fan blade 31 of the above-mentioned hot air machine 3 includes a base plate 310, the two side surfaces of the base plate 310 are respectively provided with a first blade 311 and a second blade 312, wherein the first blade 311 and the second blade 312 are respectively arranged along the circumferential direction with the center axis of the fan blade 31 as the center, and the wall of the above-mentioned inner container 10 is provided with an air inlet 101 opposite to the second blade 312 of the above-mentioned fan blade 31. The above-mentioned cooking device 1 further includes a purification cavity 50 arranged outside the above-mentioned inner container 10 and used for purifying the gas entering therein, and respectively having a second air inlet 514 communicated with the outside and a first air outlet 52 fluidly connected with the above-mentioned air inlet 101.

[0051] In the working state of the integrated cooking device, the hot air machine 3 rotates to form a hot air circulation in the inner container 10 through the first blade 311, so as to realize hot air heating of food. Meanwhile, the rotation of the second blade 312 forms a negative pressure at the air inlet 101. Under the action of the negative pressure, external air is introduced into the inner container 10 through the air inlet 101, so as to realize air induction and moisture removal of the inner container 10, avoid excessive humidity of the inner container 10 during baking to affect the cooking effect, and have a simple structure without the need to additionally add a blowing device. Moreover, the external air is purified by the purification cavity 50 before entering the inner container 10, so as to remove impurities in the air and make the air entering the inner container 10 clean, thereby ensuring the safety of cooking.

[0052] Further, as shown in Figure 4 In the embodiment, the hot air machine 3 is vertically installed on the top wall of the inner container 10, the motor 32 of the hot air machine 3 is located above the inner container 10, the output shaft 321 of the motor 32 penetrates into the inner container 10 to install the fan blade 31 on the inner top surface of the inner container 10, and the air induction cavity 40 is arranged on the top wall of the inner container 10. Specifically, the air inlet 101 is arranged on the top wall of the inner container 10, and the air induction cover 4 is arranged on the outer top surface of the inner container 10 to form the disc-shaped air induction cavity 40. Thus, the up-down hot air circulation can be formed in the inner container 10, so as to ensure the cooking efficiency and simultaneously realize the air-frying function of the integrated cooking device.

[0053] Further, the cooking device 1 further comprises an air induction cavity 40 arranged on the inner container 10 and having the air inlet 101 located in the air induction cavity 40, and further having a first air inlet 401 in fluid communication with the first air outlet 52 of the purification cavity 50. The air induction cavity 40 can improve the air induction efficiency of the inner container 10 and make the clean air be smoothly introduced into the inner container 10. In the embodiment, the purification tank 5 opposite to the air induction cavity 40 is arranged above the inner container 10, the purification tank 5 has a cylindrical shape, the inner cavity of the purification tank 5 forms the purification cavity 50, and the first air outlet 52 is arranged on the bottom wall of the purification tank 5. The installation space above the inner container 10 is relatively large, the arrangement can make the purification cavity 50 and the air induction cavity 40 be more reasonably arranged in the device, and the air is introduced into the inner container 10 from top to bottom, so as to ensure the smoothness of air induction.

[0054] Furthermore, the cooking apparatus 1 also includes a cooling device 7 for cooling the gas in the air intake chamber 40. By cooling the gas in the air intake chamber 40, the gas introduced into the inner pot 10 is low-temperature gas, which can quickly reduce the internal temperature of the inner pot 10, thereby effectively shortening the waiting time for the user when cooking multiple dishes continuously. In addition, by appropriately reducing the internal temperature of the inner pot 10 at the end of cooking, it is also possible to prevent the user from being burned by the excessively high internal temperature of the inner pot 10 (while avoiding the rapid drop in temperature of the cooked food).

[0055] Furthermore, there are various ways to implement the cooling device 7 in cooling the gas in the air-drawing chamber 40. Preferably, the first air outlet 52 of the purification chamber 50 is connected to the first air inlet 401 of the air-drawing chamber 40 via the air guide pipe 6, and the cooling device 7 is used to cool the gas flowing through the air guide pipe 6. In this way, the cooling device 7 can cool the gas in the air-drawing chamber 40 by reducing the temperature of the gas flowing through the air guide pipe 6. More preferably, the cooling device 7 is located outside the air guide pipe 6. In this embodiment, specifically, there is a vertical gap between the bottom surface of the purification tank 5 and the air-drawing chamber 40, and the air guide pipe 6 is vertically connected between the bottom of the purification tank 5 and the air-drawing chamber 40. The cooling device 7 is vertically located between the purification tank 5 and the air-drawing hood 4, and one end of the cooling device 7 is connected to the air guide pipe 6, thereby cooling the gas in the air guide pipe 6.

[0056] Furthermore, such as Figures 9-11 As shown, the control unit of the cooling device 7 is located in the purification chamber 50, and also includes a trigger 541 for triggering the control unit of the cooling device 7 and a shield 54 for controlling the opening and closing of the first air outlet 52. The shield 54 operates synchronously with the trigger 541 and has at least the following states:

[0057] In the first state, the shielding member 54 shields the first air outlet 52 and closes the first air outlet 52, and the trigger member 541 is disengaged from the control part 71 of the cooling device 7, and the cooling device 7 is not working; at this time, it is in the normal baking state, the outside gas is not replenished into the inner liner 10 through the air inlet 101, and the inner liner 10 exhausts normally.

[0058] In the second state, the shielding member 54 is offset from the first air outlet 52, causing the first air outlet 52 to open, and the trigger member 541 is disengaged from the control part 71 of the cooling device 7, so the cooling device 7 is not working; at this time, it is in the state of induced ventilation and dehumidification, and the clean gas after purification is introduced into the inner liner 10 through the air inlet 101 to achieve the forced ventilation and dehumidification of the moisture in the inner liner 10.

[0059] In the third state, the shielding member 54 is misaligned with the first air outlet 52 to open the first air outlet 52, and the trigger member 541 is in contact with the control part 71 of the cooling device 7, and the cooling device 7 is working. At this time, the cooling device 7 cools the clean gas introduced into the inner container 10, thereby reducing the temperature inside the inner container 10.

[0060] Preferably, the shielding member 54 and the trigger member 541 are integrated, thereby better realizing the synchronous action of the shielding member 54 and the trigger member. Specifically, in the embodiment, the shielding member 54 is a plate member matching the size of the first air outlet 52 and horizontally attached along the plane of the first air outlet 52, and the plate member is a circular plate, and the trigger member 541 is a block-shaped metal bridge vertically protruding along the circumference on one side of the shielding member 54, and the control part 71 is a metal base capable of being in contact with the metal bridge to form a conduction state. In this way, the trigger member 541 can be better in contact with or separated from the control part 71 through the action of the shielding member 54, thereby better realizing the on-off control of the cooling device 7. In the embodiment, the control part 71 of the cooling device 7 is a block, and the control part 71 is provided with a positioning groove 711 matching the size of the trigger member 541, thereby enabling each trigger member 541 to stably contact the corresponding control part 71, and ensuring the reliable opening of the cooling device 7.

[0061] Further, in the embodiment, as shown in Figure 10 The first air outlet 52 is three and uniformly distributed along the circumference with the center axis of the purification chamber 50 as the center on the bottom wall of the purification tank 5, and the first air inlet 401 is also three and corresponds to the first air outlet 52 one by one, and each first air inlet 401 is connected to the corresponding first air outlet 52 through the gas guide pipe 6. Moreover, at least one of the gas guide pipes 6 is provided with the cooling device 7, and the shielding member 54 is also at least two and corresponds to the first air outlet 52 one by one. In this way, the air induction efficiency of the inner container 10 can be improved, and the cooling efficiency of the induced air can be improved through multiple cooling devices 7. In the embodiment, the cooling device 7 is installed on each of the two gas guide pipes 6. The motor 32 of the hot air machine 3 is arranged between the bottom surface of the purification tank 5 and the top surface of the air induction cover 4 and located in each gas guide pipe 6, and the other end of each cooling device 7 is in contact with the motor 32. In this way, the hot air machine 3 can be reasonably arranged on the top of the inner container 10, and the motor 32 of the hot air machine 3 can be cooled through the cooling device 7, thereby avoiding the high temperature of the working environment of the motor 32.

[0062] Further, each of the above-mentioned shielding members 54 can swing back and forth along the corresponding inner end face of the purification cavity 50 with the corresponding first air outlet 52 as the center under the action of the driving mechanism 53, so that the gas in the purification cavity 50 can flow out of each first air outlet 52 more smoothly, and the opening and closing control of each first air outlet 52 can be better realized by the driving mechanism 53. Specifically, as shown in Figure 9 The driving mechanism 53 includes a push rod motor 531, a rotating shaft 534 arranged along the central axis direction of the purification cavity 50, a connecting rod 533 corresponding to each shielding member 54, and a connecting rod 532. The output shaft 5311 of the push rod motor 531 extends horizontally, each connecting rod 533 extends radially, one end of each connecting rod 533 is fixed to the inner side of the corresponding shielding member 54, and the other end is fixed to the rotating shaft 534, and the connecting rod 532 extends horizontally, one end of the connecting rod 532 is pivoted to the rotating shaft 534, and the other end is pivoted to the output shaft 5311 of the push rod motor 531. In this way, the push rod motor 531 works to drive the connecting rod 532 to rotate the rotating shaft 534, thereby driving each shielding member 54 to move synchronously to realize the opening and closing control of each first air outlet 52, and to realize the opening and closing control of each cooling device 7. In this embodiment, the purification cavity 50 is provided with a shaft seat 535 for mounting the rotating shaft 534.

[0063] Further, as shown in Figure 3 The cooking device 1 further includes a door body 11 for covering the front opening of the inner container 10, and the door body 11 has a ventilation interlayer 110 extending upward and downward. The ventilation interlayer 110 has an upper ventilation opening 111 and a lower ventilation opening 112, and one of the ventilation openings is in fluid communication with the second air inlet 514, and the other ventilation opening is in communication with the outside.
