The technical scheme has the following technical effects:

1. the rotary limiting device limits the machine head to be turned and switched between a first station butted with a pot and a second station separated from the pot, namely, in the range limited by the rotary limiting device, the machine head can rotate and open and close relative to the machine body in the height direction of the machine body, an opening space is formed between the machine head and the bearing table, the height of the opening space is determined by the distance between the machine head and the bearing table, when the machine head is turned from the first station to the second station, the distance between the machine head (the position butted with the pot on the machine head) and the bearing table is increased, and the height of the opening space is also increased. Compared with the prior art that the telescopic machine head only does telescopic motion in a fixed open space and cannot bring height change of the open space, the height of the open space can be changed by the rotary machine head, so that a larger pot taking and placing space and a degree of freedom for taking and placing a pot can be provided, and a user can take and place the pot more conveniently. Such as: for the cooking utensil with the external pot, the pot is basically placed on a bearing table of a machine body in a translation mode, if the height of an open space is too small, the pot is easy to touch a machine head or the bearing table when being placed and placed, so that the pot is inclined or overturned possibly, a user needs to carefully hold the pot, and the use experience is poor; however, in the invention, after the machine head is turned from the first station to the second station, the height of the open space is increased, so that a larger space is formed between the bearing table and the machine head to avoid a pot, the pot is not easy to touch the bearing table or the machine head when being taken and placed, and a user can obtain better taking and placing experience.

Example one

Referring to fig. 1 to 3, a steam heating type cooking appliance according to an embodiment of the present invention includes a body 100 and a pot 200, wherein a head 110 is disposed on an upper portion of the body 100, a susceptor 120 is disposed on a lower portion of the body 100, the pot 200 is placed on the susceptor 120, an open space for accommodating the pot 200 is formed between the head 110 and the susceptor 120, the head 110 and the body 100 are connected by a rotation limiting device, and the rotation limiting device limits the head 110 to be turned and switched between a first position abutting against the pot 200 and a second position separated from the pot 200.

Specifically, the method comprises the following steps: the machine body 100 of the embodiment is provided with a steam generator 150 (for example, a water storage type boiler, an instant heating type boiler, etc.) and a water pump 140 inside, one side of the machine body 100 is provided with a water tank 130, the water pump 140 works to drive the water pump 140 in the water tank 130 into the steam generator 150, the machine head 110 is provided with a steam output port 111, and the steam output port 111 is communicated with the steam generator 150 through a hose. The pot 200 of the present embodiment includes a pot body 220 and a pot cover 210, the pot 200 is placed on the supporting table 120 in a state that the pot cover 210 covers the pot body 220, and when the pot 200 is taken out after cooking, the state that the pot cover 210 covers the pot body 220 is still maintained, so that heat loss can be reduced, and the pot 200 can maintain a longer heat preservation time after leaving the machine body 100; the cooker lid 210 is provided with a steam input port 211, and the above-mentioned butt joint of the machine head 110 to the cooker 200 means that the steam output port 111 on the machine head 110 is in sealed butt joint with the steam input port 211 on the cooker lid 210, and in actual work, the steam generator 150 heats steam generated by water, and the steam is introduced into the cooker 200 through the steam output port 111 and the steam input port 211 to heat food.

The open space is an open space defined between the machine head 110 and the carrying platform 120, the horizontal direction is not limited except for the machine body 100, and the distance between the machine head 110 and the carrying platform 120 determines the height of the open space, therefore, the pot 200 is basically placed on the carrying platform 120 of the machine body 100 in a translation manner, if the height of the open space is too small, the pot 200 is easy to touch the machine head 110 or the carrying platform 120 when being placed, which may cause the pot 200 to tilt or overturn, so that a user needs to carefully hold the pot 200, if the open space is enlarged by increasing the height of the machine head 110, although the problem of placing and placing the pot can be solved, part of the open space is in a waste state, and the height of the machine body is also increased.

The embodiment of the present invention proposes the concept of a rotary handpiece, which changes the height of an open space through the rotary opening and closing movement of the handpiece 110 in the height direction of the machine body 100, that is, as described above: the machine head 110 is turned and switched between a first station for butting against the pot 200 and a second station separated from the pot 200. When the cookware 200 is taken and placed, the machine head 110 is turned from the first station to the second station, the distance between the machine head 110 (the position of the machine head 110, which is butted with the cookware 200) and the bearing table 120 is increased, namely the height of an open space is increased, so that a larger cookware 200 taking and placing space and a greater degree of freedom are provided, and a user can take and place the cookware 200 more conveniently; during cooking, the machine head 110 is turned over from the second station to the first station and is butted with the pot 200, so that the pot 200 is conveniently taken and placed, and waste of an open space is avoided.

Referring to fig. 3, in the embodiment of the present invention, the rotation limiting device limits the turning angle of the machine head 110, so that the machine head 110 is only turned and switched between the first station and the second station, and damage to the machine head 110 due to excessive turning is prevented, and particularly, the first station of the machine head 110 is limited, and on the basis of realizing the butt joint between the machine head 110 and the pot 200, damage to the butt joint between the machine head 110 and the pot 200 due to excessive pressing of the pot 200 by the machine head 110 can be prevented. Preferably: in the embodiment of the present invention, an included angle α between the machine head 110 and the horizontal plane at the second station is defined as 10 ° to 45 °, and it should be noted that: if the machine head 110 is in a horizontal state at the first station, the included angle α between the machine head 110 and the horizontal plane at the second station is the machine head 110 turning angle defined by the rotation limiting device, but in an actual product, because of factors such as part processing errors and assembly errors, the machine head 110 at the first station has a certain amount of up-and-down floating relative to the horizontal state, and therefore, the machine head 110 turning angle defined by the rotation limiting device is not smaller than the included angle α between the machine head 110 and the horizontal plane at the second station. In addition, steam generating device 150 in machine body 100 carries steam to head 110 through steam conveying pipe, and let in steam to pan 200 by head 110, when the contained angle of first station and second station is less than 10 °, the angle that head 110 overturns is undersized, pan 200 is difficult to install in place, when the contained angle of first station and second station is greater than 45 °, the angle that head 110 overturns is great, the steam conveying pipe bending angle of head 110 and machine body 100 upset department is too big, easily leads to steam conveying pipe fracture.

According to the scheme of the embodiment of the invention, it can be understood that: if the included angle alpha between the machine head 110 and the horizontal plane at the second station is less than 10 degrees, the rotation stroke of the machine head 110 is too small, which not only increases the design difficulty of the rotation limiting device, but also can not fully exert the special space advantages of the rotary machine head 110; if the included angle α between the machine head 110 and the horizontal plane at the second station is greater than 45 °, a larger space needs to be reserved above the cooking appliance in a use environment to avoid the machine head 110 in an open state, which causes limitation in the use environment, and an excessive rotation stroke makes manual operation of a user more laborious, so that the included angle α between the machine head 110 and the horizontal plane at the second station is limited within a range of 10 ° to 45 °, which facilitates opening and closing operations of the cover while obtaining good use experience, and the included angle α between the machine head 110 and the horizontal plane at the second station can be set to 15 °, 20 °, 25 °, 30 °, 35 °, 45 ° and the like according to actual product requirements.

The rotation limiting device of the embodiment of the invention is also provided with a driving element which is used for driving the machine head 110 to be turned upwards from the first station to the second station and allowing the machine head 110 to be manually turned from the second station to the first station.
