Detailed Description

The utility model is described in further detail below with reference to the accompanying examples.

Example 1

As shown in fig. 1 to 3, the air fryer includes a body 11 and a cover 12 hinged on the body 11, the body 11 has a cooking cavity 110 with an upper opening, and the cover 12 can be turned over up and down relative to the body 11 to open or close the cooking cavity 110 of the body 11. The steam generating device is provided at the bottom of the cooking cavity 110 for generating high temperature steam that diffuses upward.

The steam generating device includes a hot plate 20, a water pipe, a water pump (not shown), and a water tank (not shown). The water pump can pump the water in the water tank to the heating plate 20 through the water pipe.

Referring to fig. 3, the heating panel 20 includes a panel body 21 having an opening at the top and a heating pipe 22 provided at the bottom of the panel body 21. The tray body 21 includes a bottom wall 211 and a circumferential wall 212 extending upwardly from the bottom wall 211, the bottom wall and the circumferential wall 212 together defining the water containing chamber 200. The heating pipe 22 is installed on the outer wall surface of the bottom wall 211 of the tray body 21 for heating the water in the water containing chamber 200 of the tray body 21.

The annular wall 212 of the tray body 21 is provided with a connecting hole 23 for engaging the water duct 30, the connecting hole 23 being adjacent to the bottom wall of the tray body 21.

The first end of the water pipe 30 is connected with the connection hole 23 of the heating plate 20, and the second end is connected with the outlet of the water pump. An annular groove 31 is opened on the outer peripheral wall of the first end of the water duct 30, and in a state that the water duct 30 is inserted into the connecting hole 23 of the tray body 21, the peripheral edge portion 230 of the connecting hole 23 of the heating tray 20 is limited in the annular groove 31 and is in sealing contact with the inner wall of the annular groove 31.

A sealing ring 40 is also arranged in the annular groove 31 of the water pipe 30. The sealing ring 40 is abutted between the peripheral portion 230 of the connection hole 23 and the side wall surface of the annular groove 31, thereby ensuring the firmness and the sealing property of the connection between the water pipe 30 and the heating plate 20.

In order to facilitate the water duct 30 to be smoothly inserted into the connection hole 23, the outer peripheral wall of the first end of the water duct 30 of the present embodiment has a guide surface 32 that is inclined inward in the direction in which the first end of the water duct 30 is inserted into the connection hole 23, and preferably, the guide surface 32 has a convex curved surface structure as a whole.

Generally, the inner diameter of the connection hole 23 should be identical to the inner diameter of the annular surface defined by the bottom surface of the annular groove 31, or the inner diameter of the connection hole 23 should be slightly smaller than the inner diameter of the annular surface defined by the bottom surface of the annular groove 31. Wherein, for the convenience of assembly, the water duct 30 adopts a flexible tube structure with a certain deformation at least at a portion of the first end, thereby facilitating the insertion into the connection hole 23 from the outside.

The outer circumferential wall of the water duct 30 of this embodiment further has a limiting flange 33 protruding outward in the radial direction, and the limiting flange 33 is disposed adjacent to the first end of the water duct 30 and can form a limiting position with a corresponding component (such as the limiting plate 111 in fig. 3) on the pot body 11 of the air fryer, so that the water duct can be effectively prevented from being pulled out due to external force.

When the water pipe 30 is inserted into the connecting hole 23 of the heating plate 20, the peripheral portion 230 of the connecting hole 23 of the heating plate 20 can be limited in the annular groove 31 of the water pipe and is in sealing contact with the inner wall of the annular groove 31, so that the first end of the water pipe 30 cannot be loosened, the sealing performance of the connecting position between the water pipe 30 and the heating plate 20 is effectively guaranteed, and the problem of steam leakage is avoided. On the other hand, during assembly, only the water pipe 30 needs to be inserted into the connecting hole 23 of the heating plate 20, and the peripheral part 230 of the connecting hole 23 of the heating plate 20 is limited in the annular groove 31, so that the assembly process is convenient, the assembly efficiency is improved, and the production cost is reduced.

Example 2

Referring to fig. 4 to 7, the present embodiment is different from embodiment 1 in that: the sealing ring 40 is omitted, and correspondingly, the peripheral portion 230 of the connecting hole 23 is bent outward to form an annular flange 24, wherein the annular flange 24 is in sealing contact with the bottom surface of the annular groove 31 after the water pipe 30 is assembled in place.

In the present embodiment, the inner diameter of the annular surface defined by the inner wall surface of the annular flange 24 should be the same as the inner diameter of the annular surface defined by the bottom surface of the annular groove 31, or the inner diameter of the annular surface defined by the inner wall surface of the annular flange 24 should be slightly smaller than the inner diameter of the annular surface defined by the bottom surface of the annular groove 31. In addition, the length of the annular flange 24 in the axial direction of the connecting hole 23 is matched with the width of the annular groove 31, so that the annular flange 24 can be effectively ensured to be smoothly embedded in the annular groove 31 and the problem of shaking of the water conveying pipe 30 caused by insufficient length of the annular flange 24 can be avoided,
