Referring to fig. 1 to 4, a steam cooking apparatus 100 according to an embodiment of the present invention includes a chamber 10, a steam assembly 11, and a showerhead assembly 12. The steam assembly 11 is used to generate and deliver steam. The nozzle assembly 12 includes a rotating shaft 121 and a first nozzle 122. The rotation shaft 121 communicates with the steam assembly 11 (not shown) and can rotate relative to the chamber 10. The first nozzle 122 communicates with the rotary shaft 121. In the case where the rotating shaft 121 is rotated to be greater than the first angle a1, the first nozzle 122 protrudes into the chamber 10 toward the bottom of the chamber 10.

Above-mentioned steam cooking equipment 100, under the condition of the food of cooking liquid, axis of rotation 121 can drive first shower nozzle 122 and rotate to the position that is greater than first angle a1 for in first shower nozzle 122 can stretch into cavity 10 and dip in liquid, in the liquid was introduced and the come-up to the liquid surface to the direction of cavity 10 bottom to steam accessible first shower nozzle 122, thereby can realize the culinary art effect of the bubble of beating milk.

Specifically, in the embodiment shown in fig. 2, the steam cooking apparatus 100 may have a plurality of side plates 102, and the plurality of side plates 102 surround an inner side wall 101 constituting the cavity 10. The rotating shaft 121 rotates relative to one of the side plates 102 to form a rotating angle, and when the rotating shaft 121 rotates, the communicating first nozzle 122 is driven to rotate synchronously along the rotating shaft L1 of the rotating shaft 121. In the case that the rotation angle is increased and is greater than the first angle a1, the relative distance between the first nozzle 122 and the side plate 102 is greater, and the first nozzle 122 tends to be close to the center of the cavity 10, so that steam can be delivered into the cavity 10 through the first nozzle 122, and the steam can be delivered to the position of the first nozzle 122 along the first nozzle 122 to achieve the corresponding cooking effect.

It will be appreciated that a user may need to generate foam in the liquid to be cooked (e.g. milk, coffee) in order to achieve a particular cooking effect (e.g. drawing a particular pattern). Specifically, in the embodiment of the present invention, when the rotation angle of the rotation shaft 121 is greater than the first angle a1, it means that the first nozzle 122 extends downward into the cavity 10 to a specific position, so that the liquid to be cooked can be put into the cavity 10, and the first nozzle 122 is immersed below the liquid level of the liquid from the specific position, and then the first nozzle 122 delivers steam into the liquid, so that bubbles with a corresponding degree can be generated, and the milk frothing effect can be achieved.

Regarding the first angle a1, it should be apparent to those skilled in the art that the first angle a1 can be determined according to actual requirements, specific structure of the inner sidewall 101 of the chamber 10, and the like. In some embodiments, the first angle a1 is 45, 50, 60, 70, 80, 89, 90 degrees.

In addition, in some embodiments, first nozzle 122 may be fixed relative to rotating shaft 121, and regardless of the rotation angle of rotating shaft 121, first nozzle 122 and rotating shaft 121 may remain relatively stationary, which may make the overall structure of nozzle assembly 12 simple and easy to implement. In other embodiments, the first nozzle 122 may be movable with respect to the rotating shaft 121, for example, the first nozzle 122 may be retractable and extendable according to the rotating angle of the rotating shaft 121, and the first nozzle 122 may be oriented at the bottom of the chamber 10, or may be oriented in a direction other than the bottom of the chamber 10, so as to save the space occupied by the first nozzle 122 when the steam is not required to be delivered through the first nozzle 122.

Referring to fig. 3 and 5, in some embodiments, the inner sidewall 101 of the chamber body 10 is provided with a receiving groove 103. The groove wall of the accommodating groove 103 is provided with a limit through hole 104. The rotating shaft 121 penetrates the limiting through hole 104. In the case where the rotation shaft 121 is rotated to be smaller than the second angle a2, the first nozzle 122 is located in the receiving recess 103. The first angle a1 is greater than or equal to the second angle a 2.

Thus, the first nozzle 122 can be conveniently stored, and the cooking space in the cavity 10 can be prevented from being occupied.

Specifically, in the illustrated embodiment, the receiving groove 103 is provided on one of the side plates 102, and the receiving groove 103 is formed in a recessed structure on the side plate 102. The steam cooking apparatus 100 is provided with a limiting through hole 104 on a wall of the accommodating recess 103, and the rotation shaft 121 may penetrate the limiting through hole 104 and communicate with the steam assembly 11 at the other side of the limiting through hole 104. In the case where the steam assembly 11 generates steam and delivers the steam along the path communicated with the rotating shaft 121, the steam generated by the steam assembly 11 can be delivered to the position of the first nozzle 122 along the rotating shaft 121 and finally delivered into the chamber 10 through the first nozzle 122.

On the basis of the above embodiment, when the rotation angle of the rotation shaft 121 is smaller than the second angle a2, it means that the first nozzle 122 is close to the side plate 102 provided with the accommodating recess 103 and is located in the accommodating space formed by the accommodating recess 103, and the accommodating recess 103 has an accommodating effect on the first nozzle 122, so that the first nozzle 122 is not protruded into the cavity 10, which results in occupying too much space and being inconvenient for placing a large object into the cavity 10.

Furthermore, the rotation shaft 121 is inserted into the limiting through hole 104, so that a pivot point for the rotation of the rotation shaft 121 can be formed, and the limiting through hole 104 plays a role of limiting a rotation space when the rotation shaft 121 rotates.

The second angle a2 can be determined by those skilled in the art according to the actual application requirements, the specific structure of the inner sidewall 101 of the chamber 10 and other limitations. In some embodiments, the second angle a2 is 20 degrees, 30 degrees, 40 degrees, 45 degrees. The first angle a1 may be greater than the second angle a2, and may also be equal to the second angle a 2. In one embodiment, the first angle a1 is 45 degrees and the second angle a2 is 45 degrees.

Referring to fig. 5 and 6, in some embodiments, the showerhead assembly 12 includes a securing member 123 and a bearing member 124. The fixing member 123 is fixedly fitted over the rotation shaft 121, and the bearing member 124 is defined between the fixing member 123 and the limiting through-hole 104.

In this way, the stability of the rotation shaft 121 when rotating can be improved, and the airtightness of the chamber 10 can be improved.

Specifically, in the illustrated embodiment, the fixing member 123 and the bearing member 124 are disposed on the side of the side plate 102 away from the cavity 10, the bearing member 124 is sleeved on the rotating shaft 121 and attached to the edge of the limiting through hole 104, so that the rotating shaft 121 can increase the contact area with the limiting through hole 104 through the bearing member 124 when rotating, thereby increasing the stressed area of the rotating shaft 121, the rotating shaft 121 further fixes the bearing member 124 on the rotating shaft 121 in a manner of fastening and fixing the fixing member 123, and thereby improving the stability of the rotating shaft 121 rotating around its own axis.

In addition, the bearing member 124 may also occupy the gap between the rotating shaft 121 and the limiting through hole 104 in an interference manner, so that the steam in the cavity 10 may not flow out of the cavity 10 along the gap between the rotating shaft 121 and the limiting through hole 104, thereby improving the airtightness of the cavity 10.

In some embodiments, the bearing member 124 may include a silicone sleeve. Specifically, in some embodiments, by using silicone as the material of the bearing member 124, the bearing member 124 has good wear resistance and can withstand a certain degree of deformation, and in other embodiments, a bearing and a bushing may be used as an accessory for improving the stability of the rotating shaft 121 during rotation, so that the wear of the rotating shaft 121 during rotation can be reduced, which is beneficial to improving the service life of the rotating shaft 121, and avoiding frequent maintenance and replacement of parts. Thus, the service life of the rotating shaft 121 can be improved.

Of course, it will be apparent to those skilled in the art that in other embodiments, the bearing member 124 may also include a bearing, a bushing, or the like that also provides a securing function, thereby achieving the same or similar effect as the above-described embodiments. The detailed description is not avoided, and the embodiments are not limited herein.

Referring to fig. 4-6, in some embodiments, the rotating shaft 121 has an air inlet 1211. The rotary shaft 121 communicates with the steam module 11 through the inlet 1211. The gas inlet 1211 is located at the top of the chamber 10 with respect to the first showerhead 122.

In this way, the steam can be smoothly input into the cavity 10.

It will be appreciated that, for steam, which generally has a gas density less than that of air and therefore tends to flow upward, the steam is subjected to an upward gas pressure when being delivered downward by being input from the gas inlet 1211 positioned at the top of the chamber 10 and output from the first nozzle 122 positioned at the bottom of the chamber 10, so that the flow rate of the steam can be slowed down. Under the condition of realizing the milk frothing function through the first nozzle 122, the flow speed of steam in the input liquid is low, and large airflow is not easy to form, so that large bubbles are formed when the flowing gas floats to the surface of the liquid, and the condition of liquid splashing caused by bubble rupture can be avoided.

Referring to fig. 3, in some embodiments, the rotating shaft 121 has a rotating shaft L1 along its own rotating axial direction. First nozzle 122 has a tube axis L2 in the direction it delivers steam. The rotation axis L1 and the tube axis L2 are substantially parallel and are offset from each other.

Thus, the steam can be prevented from entering the chamber 10 too fast, and the state switching of the first nozzle 122 between the storage and the delivery of the steam can be conveniently realized.

Specifically, in the embodiment shown in fig. 3 and 6, the showerhead assembly 12 may include an adapter tube 125. One end of the adapter tube 125 is connected to the rotating shaft 121, and the other end is connected to the first nozzle 122. The steam may be sequentially delivered along the rotation shaft 121, the adaptor pipe 125, and the first nozzle 122. An angle is formed between the length direction of the adapter tube 125 and the rotation axis L1 of the rotation shaft 121. An angle is formed between the longitudinal direction of the adapter tube 125 and the tube axis L2 of the first nozzle 122.

By changing the angle formed by the communication between the adapter tube 125 and the rotating shaft 121 and the angle formed by the communication between the adapter tube 125 and the first nozzle 122, the rotating shaft L1 of the rotating shaft 121 and the tubular shaft L2 of the first nozzle 122 can be parallel to each other, and the adapter tube 125 communicated between the rotating shaft 121 and the first nozzle 122 can prevent the rotating shaft L1 and the tubular shaft L2 from overlapping to form a state of mutual dislocation.

Of course, it is obvious to those skilled in the art that the rotation axis L1 and the tube axis L2 are substantially parallel to each other by adjusting the angle formed by the communication between the adapter tube 125 and the rotation axis 121 and the angle formed by the communication between the adapter tube 125 and the first nozzle 122, so that the included angle between the rotation axis L1 and the tube axis L2 is within the allowable range.

It can be understood that, since the communication position between the adapter tube 125 and the rotating shaft 121 needs to be connected by an elbow, and the communication position between the adapter tube 125 and the first nozzle 122 needs to be connected by an elbow, in the case that the steam is delivered to the elbow between the adapter tube 125 and the rotating shaft 121, and is delivered to the elbow between the adapter tube 125 and the first nozzle 122, the flow speed of the steam is reduced, so that the flow speed of the steam finally delivered to the cavity 10 at the first nozzle 122 is also reduced correspondingly, and the steam is prevented from flowing into the cavity 10 too fast.

Moreover, because the rotating shaft L1 and the tubular shaft L2 are staggered with each other, the rotating shaft 121 can drive the first nozzle 122 to rotate through the adapter tube 125 when rotating, so that the first nozzle 122 can rotate by taking the rotating shaft L1 as an axis and taking a gap formed by the staggered rotating shaft L1 and the tubular shaft L2 as a radius, the first nozzle 122 can extend into the cavity 10 to convey steam, and the first nozzle 122 can be switched between a storage state and a state of conveying steam.

Referring to fig. 2 and 4, in some embodiments, showerhead assembly 12 includes a second showerhead 126. The second showerhead 126 is in communication with the steam module 11. The second showerhead 126 is fixedly directed into the chamber 10. The orientation of second spray head 126 is different from the orientation of first spray head 122.

In this way, it is possible to feed steam into the chamber 10 from different directions.

Specifically, in the illustrated embodiment, the second showerhead 126 opens into the chamber 10 and has a fixed orientation. When the user needs to use the milk frothing function, the first nozzle 122 can be extended into the cavity 10 by rotating the rotating shaft 121, and when the user needs to use other cooking functions (such as air frying), the steam can be directly conveyed along the second nozzle 126, so that the steam can flow into the cavity 10 in a direction different from that of the first nozzle 122, and the corresponding cooking function can be conveniently realized.

Referring to fig. 4, in some embodiments, the steam cooking apparatus 100 includes an on-off valve 13. The switch valve 13 is communicated between the steam module 11 and the second showerhead 126. The steam cooking apparatus 100 has a first cooking mode and a second cooking mode. In the case where the steam cooking apparatus 100 operates in the first cooking mode, the switching valve 13 opens a passage between the steam assembly 11 and the second showerhead 126 to allow steam to enter the cavity 10 through the second showerhead 126. In the case where the steam cooking apparatus 100 operates in the second cooking mode, the switching valve 13 interrupts the passage between the steam assembly 11 and the second showerhead 126 to allow steam to enter the cavity 10 through the first showerhead 122.

Thus, corresponding cooking effects can be achieved according to different cooking needs.

It will be appreciated that different cooking modes may be used to deliver steam into the chamber 10 in different ways, thereby achieving different cooking functions. In the illustrated embodiment, a passage (not shown) is connected between the steam assembly 11 and the switch valve 13, and a passage (not shown) is also connected between the switch valve 13 and the second nozzle 126, so that the switch valve 13 has the function of conducting and blocking the steam from being delivered into the chamber 10 along the second nozzle 126.

Specifically, in some embodiments, the first cooking mode is an air fry mode and the second cooking mode is a whipping mode. In the case that the steam cooking apparatus 100 is in the first cooking mode, a large amount of high-temperature steam needs to be directly supplied into the cavity 10, so that the high-temperature steam can flow into the cavity 10 along the second nozzle 126 by supplying the high-temperature steam to the fixedly-arranged second nozzle 126. In the case that the steam cooking apparatus 100 is in the second cooking mode, it is required to deliver steam at a specific position so that the steam flows along the first nozzle 122 into the cavity 10 by delivering the steam to the movable first nozzle 122.

In addition, in some embodiments, the on-off valve 13 is a solenoid valve. The switch valve 13 may be normally open, that is, in a state of conducting a path between the steam component 11 and the second nozzle 126 under other conditions, and in the second cooking mode, the switch valve 13 may be powered on only when entering the second cooking mode, and in a state of powering off under other conditions, so as to avoid extra energy consumption caused by keeping the switch valve 13 conducting.

In certain embodiments, the number of second spray heads 126 is at least two.

In this way, it is possible to advantageously improve the efficiency of steam delivery to the chamber 10.

Specifically, in the embodiment shown in fig. 2, the number of the second spray heads 126 is two, and two second spray heads 126 are installed at intervals on the side plate 102 of the chamber 10 and are disposed toward the inside of the chamber 10 in the same direction. In other embodiments, the number of the second spray heads 126 may be three, four, five, or more than five. Of course, it will be apparent to those skilled in the art that the specific number of the second spray heads 126 can be determined according to the amount of steam to be delivered into the cavity 10 in the corresponding cooking mode.

The amount of steam delivered by the second nozzle 126 into the chamber 10 per unit time can also be adjusted by changing the size of the second nozzle 126. In other embodiments, a person skilled in the art may adjust the aperture and/or the number of the spray holes on the second spray head 126 according to needs, adjust the inner diameter of the tube of the second spray head 126, and adjust the spatial layout of all the spray holes relative to the tube, thereby achieving the technical effect of adjusting and improving the efficiency of the second spray head 126 to deliver the steam to the chamber 10.

Referring to fig. 2, in some embodiments, the second showerhead 126 is disposed at the bottom of the chamber 10 along the height direction of the chamber 10. Specifically, in the illustrated embodiment, the second showerhead 126 is disposed at a position spaced apart from the first showerhead 122 and at the bottom of the chamber 10 in the height direction of the chamber 10, so that the steam can be conveniently supplied into the chamber 10 at various positions.

In this manner, rapid distribution of steam throughout the chamber 10 is facilitated.

It will be appreciated that, since the high temperature steam has a tendency to flow upward, the steam is first conveyed toward the bottom of the chamber 10, so that the temperature rising tendency in the chamber 10 is from bottom to top. If the steam is delivered toward the top of the chamber 10, the steam is required to be gradually accumulated in the top space of the chamber 10 until the excessive steam is pressed to the bottom space of the chamber 10, so that a temperature rising trend is formed from top to bottom. That is, the second showerhead 126 is disposed to be inclined downward in the horizontal direction, so that the temperature rising speed of the entire space in the chamber 10 can be increased, and the steam can be rapidly distributed in the entire chamber 10.

In addition, in the illustrated embodiment, the second nozzle 126 is formed to be inclined downward along the pipe diameter direction of the second nozzle 126, so that the steam can firstly flow at the bottom of the chamber 10 and fill the bottom space of the chamber 10, and then gradually flow upward to the top of the chamber 10 after a certain time, thereby increasing the residence time of the steam at the bottom of the chamber 10 and forming a temperature rising trend in the chamber 10 from bottom to top.

In addition, it can be understood that, for those skilled in the art, on the basis of the above-mentioned embodiment, the number of the second spray heads 126 may be set to one, two, three, four, or more than four, and the second spray heads 126 are disposed at the bottom of the chamber 10 along the height direction of the chamber 10, so that the efficiency of delivering the steam into the chamber 10 by the second spray heads 126 may be improved, and the steam may be conveniently and rapidly distributed in the whole chamber 10.

Referring to FIG. 2, in some embodiments, spray head assembly 12 includes a grip 14. The grip 14 is fixedly provided on the outer surface of the first head 122.

In this manner, the position of the first nozzle 122 may be manually adjusted.

Specifically, in the illustrated embodiment, the grip portion 14 circumferentially covers the outer surface of the first nozzle 122 and is fixedly disposed with respect to the first nozzle 122. When a user needs to use the first nozzle 122, the user can hold the holding part 14 to drive the first nozzle 122 to rotate relative to the rotating shaft of the rotating shaft 121, so as to achieve the effect of manually adjusting the position of the first nozzle 122. In one embodiment, the material of the holding portion 14 is silicone, which has the characteristics of wear resistance and being able to withstand a certain deformation, so as to avoid the first nozzle 122 from being worn or contaminated due to direct contact with the surface of the first nozzle 122.
