Technical Field

[0001] The present invention relates to the technical field of kitchen appliances, and in particular to an oil fume extraction device and a cooking appliance. Background Art

[0002] As people's quality of life continues to improve, kitchen cooking appliances are becoming increasingly diverse. Microwave ovens, ovens, steamers, or multi-functional microwave ovens have gradually become essential kitchen appliances. To enhance the user experience, multiple cooking functions are often integrated into one appliance, allowing one cooking appliance to simultaneously perform multiple functions, such as combining steaming and baking functions, thereby reducing kitchen space usage.

[0003] Cooking with appliances that feature a grill often produces a significant amount of oil smoke, making effective fume management extremely important. Existing methods for controlling oil smoke fall into two main categories: one involves controlling the cooking temperature to promptly remove excess oil; the other involves adding a fume extractor to promptly remove the cooking fume.

[0004] However, this method of controlling the cooking temperature requires a long cooking time because the cooking temperature is not high, and the fat in the food is easily drained away, affecting the taste of the food. Therefore, the use of cooking appliances with oil fume extraction devices is becoming more and more common. However, when the cooking appliance is used in a non-grilling function, the oil fume extraction device can easily interfere with the use of the cooking appliance in a spatial manner, affecting the normal use of the cooking appliance, making it inconvenient to use, and greatly reducing the user experience.

[0054] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0055] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediary, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0056] Example 1

[0057] See Figure 1 , and combined with Figure 4 and Figure 5 This embodiment provides an oil fume suction device, which is suitable for a cooking appliance. The cooking appliance includes a body 2 having a cooking cavity 21.

[0058] Among them, the oil fume extraction device includes a smoke extraction head, which is provided with a smoke extraction port 112 and a flue connected to the smoke extraction port 112; the smoke extraction head is connected to the main body 2, and the smoke extraction head includes a first state in which the smoke extraction port 112 extends to the outside of the main body 2 and a second state in which the smoke extraction port 112 is retracted to the inside of the main body 2; in the first state, the oil fume in the cooking cavity 21 can enter the flue from the smoke extraction port 112 and be discharged from the flue.

[0059] For such a setting, see Figure 9 When using the baking function of the cooking appliance, the user can put the smoking head in the first state, so that the smoking port 112 of the smoking head extends to the outside of the main body 2. Therefore, when food is placed in the cooking cavity 21 for baking and cooking, a large amount of oil smoke generated in the cooking cavity 21 during the cooking process can enter the flue from the smoking port 112 and be discharged from the flue, thereby realizing the discharge of oil smoke in the cooking cavity 21.

[0060] See Figure 6 When the baking function of the cooking appliance is not used, for example, the steaming function or boiling function of the cooking appliance is used, the food is placed in the cooking cavity 21 for cooking. A large amount of oil smoke will not be generated in the cooking cavity 21, so there is no need to use the smoke outlet 112 to eliminate the oil smoke. At this time, the smoke head can be placed in the second state, so that the smoke outlet 112 of the smoke head is retracted into the inside of the body 2, which prevents the smoke head from affecting the normal use of the cooking appliance to a certain extent.

[0061] To sum up, when the grilling function of the cooking appliance is used, the cigarette head is in the first state, and the smoking port 112 can promptly absorb the fumes during the cooking process. When the grilling function of the cooking appliance is not used, the cigarette head is in the second state, which reduces the spatial interference of the cigarette head on the use of the cooking appliance to a certain extent, makes the cooking appliance more convenient to use, and greatly improves the user experience.

[0062] Preferably, see Figure 1 In this embodiment, the smoking head is provided with multiple smoking ports 112, and the multiple smoking ports 112 are arranged in an array to increase the smoking area of ​​the oil smoke, improve the smoking efficiency of the oil smoke, achieve rapid smoking, and prevent the oil smoke from overflowing and polluting the cooking environment.

[0064] See Figure 2 When the second oil fume passage 121 is in the extended state, the second oil fume passage 121 causes the first oil fume passage 111 to rise, so that the smoke outlet 112 extends to the outside of the body 2. The oil fume in the cooking cavity 21 can enter the first oil fume passage 111 and the second oil fume passage 121 from the smoke outlet 112 and be discharged from the second oil fume passage 121. Figure 3 When the second oil fume channel 121 is in the retracted state, the second oil fume channel 121 causes the first oil fume channel 111 to descend, so that the suction port 112 is retracted into the interior of the body 2 .

[0065] Please continue to see Figure 9 When using the grilling function of the cooking appliance, the user can put the smoking head in the first state, specifically, put the second oil fume channel 121 in the extended state, so that the extended second oil fume channel 121 causes the first oil fume channel 111 to rise, so that the smoking port 112 extends to the outside of the main body 2. At this time, the oil fume in the cooking cavity 21 can enter the first oil fume channel 111 and the second oil fume channel 121 from the smoking port 112, and be discharged from the second oil fume channel 121, thereby realizing the discharge of oil fume in the cooking cavity 21.

[0066] Please continue to see Figure 6 When the grilling function of the cooking appliance is not used, the smoking head can be placed in the second state, thereby shortening the second oil smoke channel 121 to cause the first oil smoke channel 111 to drop, so that the smoking port 112 is retracted into the interior of the body 2.

[0067] With such a setting, the cigarette head of this embodiment changes the position of the first oil fume channel 111 by switching the second oil fume channel 121 between the extended state and the retracted state, thereby achieving the purpose of switching the cigarette head between the first state and the second state. The operation is simple and convenient, and the user experience is improved.

[0078] Optionally, the second smoking body 13 is connected to the main body 2 by means of a snap connection, a buckle connection or a threaded connection, etc. In such a configuration, the smoking head is connected to the main body 2 via the second smoking body 13 .

[0079] Optionally, the second smoking body 13 is disposed inside the body 2, or the telescopic body 12 is disposed inside the body 2. Preferably, in this embodiment, see Figure 6 and Figure 9 The second smoking body 13 and the telescopic body 12 are both arranged inside the main body 2.

[0080] With such a setting, in the second state, when the first smoking body 11 retracts into the inside of the main body 2, the first smoking body 11, the telescopic body 12 and the second smoking body 13 are all arranged inside the main body 2. At this time, the smoking head is located as a whole inside the main body 2. Therefore, when there is no need to use the oil fume suction device to eliminate oil fume, it can completely prevent the smoking head from affecting the normal use of the cooking appliance.

[0081] Preferably, see Figure 5 and Figure 9 , and combined with Figure 10 In this embodiment, the main body 2 includes an outer shell 22 and a cover plate 26 connected to the outer shell 22.

The cooking appliance has a first cooking state using the baking function and a second cooking state using the steaming function. In the first cooking state, the baking element 4 is placed on the heating device 3. In the second cooking state, the steaming element 5 is placed on the heating device 3.

[0096] That is, when the user uses the grilling function of the cooking appliance, the grilling element 4 is placed on the heating device 3, the food is placed on the grilling element 4, and the heating device 3 heats the grilling element 4, thereby grilling the food. At this time, the cooking appliance is in the first cooking state. The smoking head is in the first state, and the smoking port 112 extends outside the body 2. The smoking port 112 can absorb the fumes generated by the grilling element 4.

[0097] When the user uses the steaming function of the cooking appliance, the user puts the smoking head in the second state, and the smoking port 112 retracts into the inside of the main body 2 to prevent the smoking port 112 from affecting the normal use of the steaming component 5. The steaming component 5 is then placed on the heating device 3, and food is placed on the steaming component 5. The steaming component 5 is heated by the heating device 3, and the steaming component 5 steams the food. At this time, the cooking appliance is in the second cooking state.

[0098] Preferably, see Figure 5 and Figure 6 In this embodiment, the steaming component 5 includes a steaming plate 51, a steamer 52 and a steaming cover 53. The steamer 52 is arranged on the steaming plate 51, and the steaming cover 53 is arranged on the steamer 52.

[0099] Preferably, see Figure 5 In this embodiment, the cooking appliance further comprises a lifting assembly 6, which is arranged between the body 2 and the heating device 3; wherein, see Figure 7 When the cooking appliance is in the first cooking state, the lifting assembly 6 can make the heating device 3 in the cooking cavity 21 at the first heating height; see Figure 8 When the cooking appliance is in the second cooking state, the lifting assembly 6 can make the heating device 3 be at a second heating height in the cooking cavity 21, wherein the first heating height is greater than the second heating height.

[0100] It should be noted that when the cooking appliance is in the first cooking state, the cooking appliance uses the grilling function, and the lifting assembly 6 places the heating device 3 at a higher height in the cooking cavity 21, so that the grilling parts 4 on the heating device 3 are located at a higher position in the cooking cavity 21, that is, the grilling parts 4 are shallower, so as to facilitate frying and grilling thinner food and facilitate taking the food out of the grilling parts 4.

[0101] When the cooking appliance is in the second cooking state, the cooking appliance uses the steaming function, and the lifting assembly 6 causes the heating device 3 to be at a lower height in the cooking cavity 21, so that the steaming assembly 5 on the heating device 3 is located lower in the cooking cavity 21, that is, the steaming assembly 5 is located at a deeper position, so as to facilitate steaming and cooking, especially steaming food with soup.

[0102] With this arrangement, the user can adjust the height of the heating device 3 in the cooking cavity 21 according to the cooking state of the cooking appliance, so that the height of the cooking utensils on the heating device 3 can automatically adapt to the cooking method.

[0103] Preferably, see Figure 5 In this embodiment, the main body 2 also includes a heat insulating member 25, which is, for example, a heat insulating seat. The heat insulating member 25 is arranged in the outer shell 22, the heating device 3 is arranged in the heat insulating member 25, and the lifting assembly 6 is arranged between the heat insulating member 25 and the heating device 3.

[0104] Preferably, see Figure 7 and Figure 8 In this embodiment, the lifting assembly 6 includes a fixing member 62, a moving member 61 and a compression elastic member 63, and the compression elastic member 63 can be a compression spring.

[0105] The fixed member 62 is fixedly connected to the main body 2, the movable member 61 is fixedly connected to the heating device 3, and the compressible elastic member 63 is connected between the fixed member 62 and the movable member 61. When the cooking appliance is in the first cooking state, the grilling component 4 and the heating device 3 cause the compressible elastic member 63 to be in the first compressed state via the movable member 61, at which time the movable member 61 is in the first position relative to the fixed member 62. When the cooking appliance is in the second cooking state, the steaming component 5 and the heating device 3 cause the compressible elastic member 63 to be in the second compressed state via the movable member 61, at which time the movable member 61 is in the second position relative to the fixed member 62.

[0106] With such an arrangement, the lifting assembly 6 causes the compression elastic member 63 to be in a first compression state through the gravity of the baking component 4 and the heating device 3, so that the movable member 61 is in a first position relative to the fixed member 62, so that the force on the lifting assembly 6 is balanced, and at this time the heating device 3 is at a first heating height at a higher position in the cooking cavity 21; the compression elastic member 63 is caused to be in a second compression state through the gravity of the steaming component 5 and the heating device 3, so that the movable member 61 is in a second position relative to the fixed member 62, so that the force on the lifting assembly 6 is balanced, and at this time the heating device 3 is at a second heating height at a lower position in the cooking cavity 21.

[0107] That is to say, the cooking appliance uses the gravity of the cooking carrier to make the compression state of the compression elastic member 63 different, so that the position of the movable member 61 relative to the fixed member 62 is different, so that the height position of the heating device 3 in the cooking cavity 21 is different, so that the height of the cooking carrier on the heating device 3 can automatically adapt to the cooking method, so that the user can use the various cooking functions of the cooking appliance.

[0108] The cooking appliance of this embodiment has the advantages of the oil fume extraction device of the first embodiment, which have been described in detail in the first embodiment and will not be repeated here.
