For example, "connected" can be fixed connection, detachable connection, or integral configuration; can be mechanical connection, or electrical connection; can be direct connection, or indirect connection through an intermediate medium, or internal communication between two devices, elements or components. Those of ordinary skill in the art can understand the specific meanings of the above terms in the embodiments of the present disclosure according to specific circumstances.
[0035] Unless otherwise specified, the term "plurality" means more than two.
[0036] As shown in Figures 1-6 The present application discloses a cooking device with steaming function. The cooking device comprises a box body 1 and a blowing assembly 2. The inside of the box body 1 has a cooking cavity, and the blowing assembly 2 is arranged at the rear of the box body 1.
[0037] As shown in Figures 1-4 and Figure 6As shown, the air blowing assembly 2 comprises a fan 21, an adapter pipe 22, an air passing pipe 23 and an exhaust valve 24. The air passing pipe 23 is used to communicate with the cooking cavity. The fan 21 has an air outlet pipe 211. In this way, under the action of the fan 21, air enters the cooking cavity through the fan, the adapter pipe 22 and the air passing pipe 23 in sequence, so that the hot air flow in the cooking cavity is quickly exhausted before the door is opened. The two ends of the adapter pipe 22 are detachably connected to the air outlet pipe 211 and the inlet of the air passing pipe 23, respectively. Along the air flow path in the air blowing assembly 2, the air outlet pipe 211 is located upstream of the air passing pipe 23. The exhaust valve 24 is used to control the opening and closing of the air passing pipe 23.
[0038] It can be understood that, since the two ends of the adapter pipe 22 are detachably connected to the air outlet pipe 211 and the inlet of the air passing pipe 23, respectively, different lengths of the adapter pipe 22 can be replaced or matched to adapt to the requirements of cooking equipment of different sizes, and the versatility is better.
[0039] In the present embodiment, as shown in Figure 1 and Figure 6 The exhaust valve 24 is located below the fan 21, and the adapter pipe 22 is vertically arranged. In this way, by replacing or matching different lengths of the adapter pipe 22, the box body 1 of different heights can be adapted, and the versatility of the air blowing assembly 2 is improved.
[0040] The adapter pipe 22 has an inlet section 2201 and an outlet section 2202. The cross-sectional area of the inlet section 2201 is different from that of the outlet section 2202, that is, there is an area difference between the two. The inlet section 2201 is inserted and matched with the air outlet pipe 211 of the fan 21, and the outlet section 2202 is inserted and matched with the inlet of the air passing pipe 23. In this way, the adapter pipe 22 adopts a variable cross-section connecting pipe 222, which can better adapt to the air outlet pipe 211 of the fan 21 and the inlet of the air passing pipe 23.
[0041] In the present embodiment, the cross-sectional area of the inlet section 2201 is larger than that of the outlet section 2202, that is, the size of the inlet section 2201 is larger than that of the outlet section 2202.
[0042] An embodiment is provided in the present application, in which, as shown in Figures 1-4 The adapter pipe 22 comprises an adapter head 221, which comprises the inlet section 2201 and a reducing section 2211. The cross-sectional area of the reducing section 2211 gradually decreases along the air flow path in the air blowing assembly 2. In this embodiment, the adapter head 221 further comprises the outlet section 2202, and the reducing section 2211 is located between the inlet section 2201 and the outlet section 2202. In this way, the different sizes of the inlet section 2201 and the outlet section 2202 are realized through the design of the reducing section 2211.
[0043] Specifically, the aforementioned outflow section 2202 is a straight pipe section with equal cross-sectional area at all points.
[0044] In other embodiments, the adapter may be used to include only the reduced section 2211, where the inlet section 2201 and the outlet section 2202 are both part of the reduced section 2211, that is, the portions of the reduced section 2211 are the inlet section 2201 and the outlet section 2202, respectively.
[0045] This application also provides another embodiment, such as Figure 6 As shown, in this embodiment, the transfer pipe 22 includes not only the adapter 221 but also a connecting pipe 222. The two ends of the connecting pipe 222 are detachably installed at the inlet of the adapter 221 and the air duct 23, respectively. Thus, by replacing or combining connecting pipes 222 of different lengths, the requirements of the fan 21's outlet duct 211 and the air duct 23 can be better met. In this embodiment, the outlet section 2202 is located on the connecting pipe 222.
[0046] To facilitate the installation of the air outlet duct 211, such as Figure 2 and Figure 3 As shown, the inner peripheral wall of the inlet section 2201 has a groove 2214 for inserting the outlet duct 211. In this embodiment, the side wall of the groove 2214 has a guide surface 2215 for guiding the outlet duct 211 into the groove 2214. The guide surface 2215 gradually slopes inward along the fluid flow path within the blower assembly 2. The presence of the guide surface 2215 guides the outlet duct 211 during insertion, allowing it to smoothly enter the groove 2214.
[0047] In order to ensure the reliable connection between the groove 2214 and the air outlet duct 211 of the fan 21, at least one of the side wall of the groove 2214 and the outer peripheral wall of the air outlet duct 211 is provided with an annular flange extending in the circumferential direction.
[0048] In this embodiment, the depth H of the groove 2214 in the insertion direction of the air outlet duct 211 is 3 to 6 mm; and / or, the minimum dimension L between the side wall of the groove 2214 and the outer peripheral wall of the air outlet duct 211 satisfies: L≥0.5 mm.
[0049] Furthermore, such as Figure 2 and Figure 4 As shown, a limiting step 2216 is provided on the outer peripheral wall of the outflow section 2202, allowing the outflow section 2202 to be inserted into the air duct 23, and the limiting step 2216 to abut against the end face at the inlet of the air duct 23. The presence of the limiting step 2216 restricts the insertion depth of the adapter 221.
[0050] In order to realize the reliability of the insertion of the outflow section 2202 into the inlet of the air duct 23, at least one of the outer circumferential wall of the outflow section 2202 and the inner circumferential wall of the air duct 23 is provided with an annular rib. In the embodiment, the annular rib 2203 is located on the outer circumferential wall of the outflow section 2202. In other embodiments, the annular rib is located on the inner circumferential wall of the air duct.
[0051] Further, the part of the outflow section 2202 inserted into the air duct 23 is defined as an insertion section 2217, the length of the insertion section 2217 is 3-6 mm; and / or, at least part of the outer circumferential wall of the insertion section 2217 is an inclined surface 2218, which gradually inclines inward along the fluid flow direction in the air blowing assembly 2. The existence of the inclined surface 2218 guides the insertion of the insertion section 2217, so that the insertion section 2217 slides more smoothly into the air duct 23.
[0052] Preferably, the inclined surface 2218 has a chamfer, and the chamfer is 0-45°.
[0053] Specifically, the cross sections of the inflow section 2201 and the outflow section 2202 are circular; or, the cross section of one of the inflow section 2201 and the outflow section 2202 is square, and the cross section of the other of the inflow section 2201 and the outflow section 2202 is circular.
[0054] In the embodiment, the air duct 23 has an inlet and an outlet, the axis of the inlet and the axis of the outlet are at an angle β, and the angle β satisfies: 150°≤β≤180°. In this way, the air flow is more smoothly flowed into the cooking cavity, and the loss of air volume is reduced. The axis of the inlet is defined as a first axis A1, and the axis of the outlet is defined as a second axis A2.
[0055] The exhaust valve 24 can adopt any structure in the prior art as long as it can realize the opening and closing of the air duct 23. In the embodiment, the air duct 23 includes a first duct 231 and a second duct 232 which are sequentially communicated along the air flow path in the air blowing assembly 2, the cross-sectional area of the first duct 231 at the position close to the second duct 232 is larger than that of the second duct 232, and the exhaust valve 24 includes a valve plate 241 and a driving mechanism 242. The valve plate 241 is located in the first duct 231. The power output end of the driving mechanism 242 is connected with the valve plate 241 to drive the valve plate 241 to rotate, thereby opening and closing the opening 2311 of the first duct 231 close to the second duct 232. In order to more reliably close the opening 2311, a sealing ring 243 is mounted on the side of the valve plate 241 facing the opening 2311, and when the valve plate 241 closes the opening, the sealing ring 243 realizes the sealing connection between the periphery of the opening and the valve plate 241.
