Detailed Description
The present invention is described in more detail below to facilitate an understanding of the invention.
As shown in fig. 2 to 4, the cooking utensil with the pressure regulating mechanism installed on the inner cover of the present invention comprises a heat insulation cover plate 2 and an inner cover 3, and an air outlet cavity 4 is arranged between the heat insulation cover plate 2 and the inner cover 3; the pressure regulating mechanism comprises a pressure regulating valve 1 and a sealing element 5, the pressure regulating valve 1 is installed on the inner cover 3 and located above the air outlet 6, a spring 7 is arranged in the pressure regulating valve 1, the upper portion of the spring 7 is installed on a valve body of the pressure regulating valve 1, and the lower portion of the spring 7 is supported on the sealing element 5. The sealing element 5 is arranged between the air outlet 6 and the pressure regulating valve 1, and the sealing element 5 is used for isolating the pressure regulating valve from the air outlet cavity; the weight of the pressure regulating valve is pressed on the spring 7 and is transmitted to the sealing element 5 through the spring, so that the bottom of the sealing element 5 blocks the air outlet 6; when the pressure of the steam pushes up the sealing element 5, the spring 7 is in a compressed state and drives the pressure regulating valve to move upwards integrally, the bottom of the sealing element 5 is separated from the air outlet hole 6, and the steam enters the air outlet cavity 4 through the air outlet hole 6; the top of the cooking utensil is provided with an air outlet 8, the air outlet 8 is communicated with the air outlet cavity 4, and the steam entering the air outlet cavity 4 is finally exhausted to the outside of the cooking utensil through the air outlet 8 (see the direction of an arrow in fig. 2).
The central axis of the exhaust port 8 and the central axis of the exhaust hole 6 are parallel to each other and are positioned on different straight lines. This arrangement enables the exhaust port 8 to avoid the position of the pressure regulating valve 1 and enables the steam to be away from the pressure regulating valve 1.
As shown in fig. 2, the sealing member 5 includes an annular step portion 51 and a protrusion portion 52, and the annular step portion 51 and the protrusion portion 52 are smoothly connected. The lower part of the spring 7 is supported on the annular step part 51, and the bottom of the bulge part 52 is matched with the size and the shape of the air outlet 6.
The annular step portion 51 is provided with an annular lip 54 extending horizontally inward.
An air chamber 53 is formed between the upper part of the convex part 52 and the annular lip 54. Because the material of bellying 52 is flexible material, is provided with the air in holding the air chamber 53, when spring 7 applys power downwards for hold air chamber 53 and bellying 52 and take place elastic deformation, and then make the bottom of bellying 52 and venthole 6 laminate more closely, sealed shutoff effect is better.
When the cooking utensil does not produce steam or the steam is little and the pressure of the steam is not enough to jack up the sealing member 5, the spring 7 and the pressure regulating valve 1 (for example, the pressure regulating valve is just heated), the weight of the pressure regulating valve is pressed on the spring 7 and is transmitted to the sealing member 5 through the spring, so that the bulge part 52 at the bottom of the sealing member 5 blocks the air outlet hole 6, a sealed micro-pressure environment is formed in the inner container of the cooking utensil, and the inner container is heated more fully and rapidly (the principle is similar to a high-pressure cooker). When the pressure of the steam is large enough to jack up the sealing element 5, the spring 7 and the pressure regulating valve 1, the sealing element 5, the spring 7 and the pressure regulating valve 1 move upwards integrally, the convex part 52 at the bottom of the sealing element 5 is separated from the air outlet hole 6, the steam enters the air outlet cavity 4 through the air outlet hole 6, and the sealing element 5 isolates the pressure regulating valve from the air outlet cavity 4, so that the steam cannot enter the pressure regulating valve and can only enter the exhaust port 8 along the air outlet cavity 4 (see the direction of an arrow in fig. 2) and is exhausted to the outside of the cooking utensil through the exhaust port 8. No steam enters the pressure regulating valve 1 in the whole process, so that the pressure regulating valve is not required to be cleaned.
Except that the pressure regulating valve is not needed to be cleaned, the utility model also has the advantage of conveniently cleaning the heat preservation cover plate as can be clearly seen by comparing with the figure 1 and the figure 4.
The pressure regulating valve 1 in the prior art shown in fig. 1 is arranged on the heat preservation cover plate 2 and is positioned in a space between the heat preservation cover plate and the inner container of the cooking utensil, and steam is discharged through the pressure regulating valve, so that the pressure regulating valve 1 is difficult to clean, and the whole heat preservation cover plate 2 is inconvenient to clean.
The utility model discloses a heat preservation apron 2 that figure 4 shows does not have the air-vent valve (because the air-vent valve is installed and is covered including), therefore heat preservation apron 2 is the planar structure basically towards the one side of cooking utensil inner bag, and it is very convenient to wash, does not have sanitary dead angle.
As a preferred embodiment, the cooking appliance can be an electric cooker, a pressure cooker, an electric chafing dish and the like.
The foregoing description of the preferred embodiments of the invention has been presented for purposes of illustration and description. Modifications and variations of the embodiments disclosed herein may be made by those skilled in the art without departing from the scope and spirit of the invention.
