[0029] Please combine Figure 1 as well as Figure 2 As shown, the present application first provides a steam exhaust structure, including an inner tank 10, an exhaust assembly 20, a flue, an oil guide pipe 30 and an oil cup 40, wherein both ends of the oil guide pipe 30 are respectively connected to the oil cup 40 and the flue; the exhaust assembly 20 includes a three-way pipe 21 and a valve body 22, the three-way pipe 21 includes a first branch 211, a second branch 212 and a third branch 213 which are mutually connected at one end, the other end of the first branch 211 is connected to the inner tank 10, the other end of the second branch 212 is connected to the flue, the other end of the third branch 213 is connected to the valve body 22, and the valve body 22 is connected to the oil cup 40 through a pipeline.

[0030] In the present application, the three branches of the three-way pipe 21 are respectively connected to the inner tank 10, the flue and the oil cup 40, so that the air in the inner tank 10 can be discharged to the flue along the first branch 211 and the second branch 212 under normal conditions. When it is necessary to forcefully exhaust steam or to clean the oil cup 40, the valve body 22 can be opened to allow the steam to pass through the first branch 211 and then be discharged to the flue and the oil cup 40 along the second branch 212 and the third branch 213. While improving the dehumidification efficiency of the inner tank 10, the steam can also be used to clean the oil cup 40 and the oil guide pipe 30 to prevent the accumulation of oil stains in the oil cup 40 or the oil guide pipe 30.

[0031] Please combine Figure 1 as well as Figure 2 As shown, in some embodiments, the exhaust assembly 20 further includes a vacuum pump 23 , and the third branch 213 is connected to the valve body 22 through the vacuum pump 23 .

[0032] When it is necessary to exhaust steam or clean the oil cup 40, open the valve body 22 and the vacuum pump 23. The vacuum pump 23 can quickly extract the steam in the inner tank 10 along the first branch 211 and the third branch 213, thereby further improving the dehumidification efficiency.

[0033] Of course, in some other embodiments, the vacuum pump 23 may also be other forms of air pumps, and the vacuum pump 23 may also be set at other positions, such as connected between the valve body 22 and the oil cup 40, etc. As long as the steam in the inner tank 10 can be extracted along the first branch 211 and the third branch 213, the present application does not make further limitations here.

[0034] Please combine Figure 2 as well as Figure 3 As shown, in some embodiments, the exhaust assembly 20 further includes a first exhaust pipe 24 , and two ends of the first exhaust pipe 24 are respectively connected to the valve body 22 and the oil cup 40 .

[0035] Under the action of the vacuum pump 23, most of the steam will pass through the valve body 22 and enter the oil cup 40. The high-temperature steam cleans the oil cup 40. The heat exchange between the steam and the oil cup 40 increases the temperature of the oil cup 40, preventing the waste oil from precipitating and forming oil scale that is difficult to clean. In addition, the steam inside the inner tank 10 can be quickly discharged.

[0036] Please combine Figure 2 as well as Figure 4 As shown, in some embodiments, the exhaust assembly 20 further includes a second exhaust pipe 25 , and two ends of the second exhaust pipe 25 are respectively connected to the valve body 22 and the oil guide pipe 30 .

[0037] Due to the action of the vacuum pump 23, a large amount of steam will enter the oil guide pipe 30 through the valve body 22, and the oil dirt residue in the oil guide pipe 30 will be cleaned by high-temperature steam, so as to prevent the accumulation of oil dirt in the oil guide pipe 30, which will lead to the deterioration of the oil guide effect or the generation of odor in the oil guide pipe 30, and at the same time, the steam inside the inner tank 10 will be quickly discharged;

[0038] Please combine Figure 2 , Figure 3 as well as Figure 4 As shown, in some embodiments, the exhaust assembly 20 also includes a first exhaust pipe 24 and a second exhaust pipe 25, and the valve body 22 is a three-way valve, which is respectively connected to the third branch 213, the first exhaust pipe 24 and one end of the second exhaust pipe 25, the other end of the first exhaust pipe 24 is connected to the oil cup 40, and the other end of the second exhaust pipe 25 is connected to the oil guide pipe 30.

[0039] The three-way valve can select the third branch 213 to be connected to the first exhaust pipe 24 or the second exhaust pipe 25, so as to switch different moisture removal paths according to actual needs, thereby increasing the versatility of the present application.

[0040] Please refer to Figure 5 As shown, in some embodiments, the oil cup 40 has a accommodating chamber 41, and a partition 42 is fixed inside the oil cup 40 to separate the accommodating chamber 41 into a steam chamber 411 and an oil storage chamber 412. The partition 42 is provided with a steam hole 421 connecting the steam chamber 411 and the oil storage chamber 412. The first exhaust pipe 24 is connected to the steam chamber 411, and the oil guide pipe 30 is connected to the oil storage chamber 412.

[0041] The diameter of the steam hole 421 is relatively small, so as to increase the flow rate of the steam after passing through the steam hole 421 , so that the steam has more impact force, thereby improving the cleaning effect of the oil cup 40 .

[0042] Specifically, when the first exhaust pipe 24 is working, steam enters the steam chamber 411 along the first exhaust pipe 24, and the steam in the steam chamber 411 enters the oil storage chamber 412 more evenly and with more impact through the steam holes 421 on the partition 42 to clean the inside of the oil cup 40. After cleaning, the remaining steam enters the flue through the oil guide pipe 30 and is discharged.

[0043] In some embodiments, the oil cup 40 and the partition plate 42 are integrally injection molded to improve the structural strength of the oil cup 40 .

[0044] Please combine Figure 4 as well as Figure 5 As shown, in some embodiments, the second exhaust pipe 25 is communicated with the upper side of the oil guide pipe 30 .

[0045] Such a design allows the waste oil generated after the oil guide pipe 30 is cleaned to flow into the oil cup 40 under the action of its own weight, thereby preventing the waste oil in the oil guide pipe 30 from flowing back into the second exhaust pipe 25 .

[0046] Please combine Figure 4 as well as Figure 5 As shown, in some embodiments, the communication position between the second exhaust pipe 25 and the oil guide pipe 30 is located close to the oil cup 40 .

[0047] Therefore, when the second exhaust pipe 25 is in operation, the steam can fully and completely clean the inside of the oil guide pipe 30 .

[0048] In some embodiments, a steam sensor (not shown) is provided in the inner tank 10, and the steam sensor is electrically connected to the valve body 22 and the vacuum pump 23 respectively; the steam sensor can detect the steam concentration inside the inner tank 10 to select a suitable dehumidification mode.

[0049] Specifically, two steam concentration levels T1 and T2 are set, T1<T2, and according to the steam concentration inside the inner tank 10, the following three dehumidification modes can be used;

[0050] 1. When the steam sensor detects that the steam concentration in the inner tank 10 is less than T1, the vacuum pump 23 and the valve body 22 are closed, and the steam is only discharged to the flue along the second branch 212, and the path is: inner tank 10 → first branch 211 → second branch 212 → flue (for the convenience of description, this path is defined as the first exhaust path);

[0051] 2. When the steam sensor detects that the steam concentration in the inner tank 10 is between T1 and T2, the vacuum pump 23 is turned on, the connection port between the three-way valve and the second exhaust pipe 25 is opened, and the steam is divided into two paths, one of which is discharged to the flue along the first exhaust path, and the other is discharged to the oil guide pipe 30 along the third branch 213 and the second exhaust pipe 25, and is discharged to the flue after the oil guide pipe 30 is cleaned. The path is: inner tank 10 → first branch 211 → third branch 213 → vacuum pump 23 → three-way valve → second exhaust pipe 25 → oil guide pipe 30 → flue (for the convenience of description, this path is defined as the second exhaust path);

[0052] The first exhaust path and the second exhaust path work at the same time, and due to the action of the vacuum pump 23, a large amount of steam will enter the oil guide pipe 30 through the three-way valve, and the oil dirt residue in the oil guide pipe 30 will be cleaned by high-temperature steam to prevent the accumulation of oil dirt in the oil guide pipe 30, which will lead to the deterioration of the oil guide effect or the generation of odor in the oil guide pipe 30, and at the same time, the steam inside the inner tank 10 will be quickly discharged;

[0053] 3. When the steam sensor detects that the steam concentration in the inner tank 10 is greater than T2, the vacuum pump 23 is turned on, the connection port between the three-way valve and the first exhaust pipe 24 is opened, and the steam is divided into two paths, one of which is discharged to the flue along the first exhaust path, and the other is discharged to the oil cup 40 along the third branch 213 and the first exhaust pipe 24. The path is: inner tank 10 → first branch 211 → third branch 213 → vacuum pump 23 → three-way valve → second exhaust pipe 25 → oil cup 40 → oil guide pipe 30 → flue (for ease of description, this path is defined as the third exhaust path);

[0054] The first exhaust path and the third exhaust path work simultaneously. Under the action of the vacuum pump 23, most of the steam will enter the oil cup 40 through the third exhaust path. The high-temperature steam cleans the oil cup 40. At the same time, the heat exchange between the steam and the oil cup 40 increases the temperature of the oil cup 40, preventing the waste oil from precipitating and forming oil scale that is difficult to clean.

[0055] It should be noted that after the third exhaust path is opened, the steam enters the oil cup 40 and forms condensed water when it is cooled, which will cause the oil cup 40 to quickly fill with oil. Therefore, the third exhaust path is only opened when the steam concentration in the inner tank 10 is too high to be greater than T2, which can prevent the oil cup 40 from being frequently filled with oil.

[0056] In addition, in some other cases, the corresponding dehumidification mode can also be selected according to the actual situation, for example,

[0057] When steaming and baking are finished, the second or third exhaust mode can be activated to quickly exhaust the steam in the inner pot 10 through the vacuum pump 23 to prevent steam leakage when the door is opened and affect the customer's use experience;

[0058] When the oil guide pipe 30 or the oil cup 40 needs to be cleaned, the second or third exhaust mode can be activated accordingly to complete the cleaning, etc. This application does not give examples one by one here.

[0059] A second aspect of the present application provides a multifunctional cooking device, comprising the above-mentioned steam exhaust structure.

[0060] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
