[0027] Please combine Figure 1 And Figure 2 As shown in the drawings, the application first provides an exhaust structure, which comprises an inner container 100, the inner container 100 is communicated with an exhaust pipe 10 and an air inlet pipe 20, the exhaust pipe 10 and the air inlet pipe 20 are communicated through a communication pipe 30, the communication pipe 30 is provided with a first valve body (not shown in the figure) for controlling opening and closing, the exhaust pipe 10 is further communicated with the outside through an external exhaust pipe 40, the air inlet pipe 20 is further communicated with the outside through an air guide pipe 50, the air guide pipe 50 is provided with a second valve body 51 for controlling opening and closing.
[0028] In the application, the exhaust pipe 10 and the air inlet pipe 20 are communicated through the communication pipe 30, and the opening and closing of the first valve body and the second valve body 51 are controlled, so that in the use process of the steam function, part of the steam can be introduced into the inner container 100 to improve the endurance of the steam function; when rapid exhaust is needed, dry gas from the outside can be introduced into the inner container 100 to squeeze out the internal steam, so as to improve the exhaust and dehumidification efficiency of the inner container 100; by switching the communication state of the pipeline for different use scenarios, the two different needs of dehumidification, exhaust efficiency and steam function endurance can be met.
[0029] Specifically, during the use of the steam function, at this time, dehumidification and exhaust are not needed, the first valve body is opened, the second valve body 51 is closed, part of the steam in the inner container 100 will enter the exhaust pipe 10 and be divided into two paths, one path is exhausted along the external exhaust pipe 40, and the other path passes through the communication pipe 30, at this time, since the first valve body is closed, the steam of this path can only return to the inner container 100 along the air inlet pipe 20 to improve the steam use efficiency, so as to improve the endurance of the steam function.
[0030] When the steaming function is used up and the steam in the inner container 100 needs to be quickly discharged, the first valve body is closed, the second valve body 51 is opened, dry air from the outside enters the exhaust structure of the present application through the air guide pipe 50, at this time, since the first valve body is closed, dry air cannot pass through the communication pipe 30, but can only enter the inner container 100 along the air inlet pipe 20, so as to squeeze the steam in the inner container 100 out of the exhaust pipe 10, and for the same reason, since the first valve body is closed, the squeezed steam can only be discharged to the outside along the outer exhaust pipe 40, and the exhaust efficiency of the inner container 100 is improved by introducing outside air to assist exhaust.
[0031] Please refer to Figure 2 and Figure 3 shown, in some embodiments, the inner container 100 and the air inlet pipe 20 are provided with a motor 61 on the side of the outer wall in communication with the air inlet pipe 20, the drive shaft of the motor 61 penetrates into the inner container 100, and a fan 62 located inside the inner container 100 is fixed on the drive shaft; the fan 62 includes a fan disc 62a and fan blades 62b, and the fan blades 62b are fixed on both sides of the fan disc 62a along the axis direction of the fan disc 62a.
[0032] When the fan 62 rotates, the fan blades 62b located on the side of the fan disc 62a away from the motor 61 rotate to blow out to realize hot air circulation in the inner container 100; the fan blades 62b located on the side of the fan disc 62a close to the motor 61 rotate to generate negative pressure between the fan disc 62a and the inner wall of the inner container 100, so as to introduce dry air from the outside into the inner container 100 through the air guide pipe 50 and the air inlet pipe 20, thereby improving the exhaust and dehumidification efficiency.
[0033] Please refer to Figure 1 and Figure 2 shown, in some embodiments, the communication port of the air inlet pipe 20 and the inner container 100 is opposite to the fan 62 along the axis direction of the fan 62, so as to reduce the distance between the negative pressure space generated by the rotation of the fan blades 62b and the air inlet pipe 20, improve the suction capacity of the negative pressure space to dry air from the outside, improve the air inlet capacity, and further improve the exhaust and dehumidification efficiency.
[0034] Please refer to Figure 1 and Figure 2 shown, in some embodiments, the outer wall of the inner container 100 is further provided with a water storage box 70 and a water pump 80, the communication pipe 30 is in communication with the water storage box 70 through a water pipe 31, and the water storage box 70, the water pump 80 and the inner container 100 are sequentially communicated.
[0035] When the steam function is used, part of the water vapor passing through the communication pipe 30 will condense in the pipe to form condensed water, and flow back to the water storage box 70 through the water pipe 31. When the inner container 100 is short of water or the amount of water in the water storage box 70 reaches a certain amount, the water pump 80 works to pump the water in the water storage box 70 into the inner container 100, thereby further improving the endurance of the steam function.
[0036] As shown in Figure 1 and Figure 2 , in some embodiments, the communication pipe 30 is inclined, and the end of the communication pipe 30 close to the air inlet pipe 20 is higher than the end close to the air outlet pipe 10.
[0037] Since the steam enters from the end of the communication pipe 30 close to the air outlet pipe 10 and exits from the end close to the air inlet pipe 20, most of the steam will condense on the side of the communication pipe 30 close to the air inlet pipe 20. By inclining the side of the communication pipe 30 close to the air inlet pipe 20 upward, on the one hand, the condensed water can flow into the water pipe 31 under the action of gravity to improve the endurance of the steam function, and on the other hand, the condensed water can be prevented from flowing into the air inlet pipe 20.
[0038] As shown in Figure 1 and Figure 2 , in some embodiments, the communication pipe 30 is in the shape of an inverted U, including a horizontal section and vertical sections at both ends of the horizontal section, wherein the horizontal section is inclined to prevent condensed water from accumulating at the bottom of the horizontal section.
[0039] As shown in Figure 1 and Figure 2 , in some embodiments, the water storage box 70 is located below the communication pipe 30, one end of the water pipe 31 communicates with the lower side of the communication pipe 30, the other end communicates with the top surface of the water storage box 70, and the bottom of the water storage box 70 communicates with the water pump 80; so that the condensed water can flow into the water storage box 70 through the water pipe 31 under the action of gravity, and the condensed water in the water storage box 70 can be pumped back into the inner container 100 as much as possible under the action of the water pump 80.
[0040] As shown in Figure 1 and Figure 2 , in some embodiments, the inner container 100 is also provided with a humidity sensor 90, and the humidity sensor 90 is electrically connected with the first valve body and the second valve body 51.
[0041] Specifically, the humidity sensor 90 is pre-set with a steam concentration T1, and when the humidity sensor 90 detects that the real-time steam concentration C in the inner container 100 is less than T1, i.e., the steam concentration is relatively low, the first valve body is closed and the second valve body 51 is opened to improve the endurance of the steam function.
[0042] When the humidity sensor 90 detects that the real-time steam concentration C in the inner container 100 is greater than T1, that is, the steam concentration is relatively high, at this time the first valve body is opened and the second valve body 51 is closed, so as to quickly discharge the moisture.
[0043] The second aspect of the present application provides a cooking device, which comprises a gas stove 200 and the above-mentioned exhaust structure, and the gas stove 200 is arranged at the top of the inner container 100.
[0044] Please refer to Figure 1 and Figure 2 In some embodiments, the outer exhaust pipe 40 is in communication with the inside of the gas stove 200; the gas discharged into the gas stove 200 through the outer exhaust pipe 40 can also have a certain heat dissipation effect.
[0045] The technical features of the above-mentioned embodiments can be combined arbitrarily, and in order to make the description simple, all possible combinations of the technical features in the above-mentioned embodiments are not described, however, as long as the combination of the technical features does not exist contradictory, it should be considered as the scope of the present application.
[0046] The above-mentioned embodiments only express several implementation manners of the present application, the description is relatively specific and detailed, but it should not be understood as the limitation of the scope of the present application. It should be pointed out that for ordinary skilled in the art, on the premise of not departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application patent should be subject to the appended claims.
