Detailed Description
In order to make the objects, technical solutions and advantages of the present utility model more apparent, the technical solutions of the present utility model will be described in detail below. It will be apparent that the described embodiments are only some, but not all, embodiments of the utility model. All other embodiments, based on the examples herein, which are within the scope of the utility model as defined by the claims, will be within the scope of the utility model as defined by the claims.
Example 1:
as shown in fig. 1 to 9, the present embodiment provides an exhaust assembly of an electric cooker, which includes a pot cover 1 and a baffle plate 2, wherein the pot cover 1 is provided with an exhaust hole 11 for exhausting steam, the baffle plate 2 is hinged with the pot cover 1 through a hinge shaft, and the baffle plate 2 can rotate around the hinge shaft on the pot cover 1. In the first state, the baffle plate 2 is overlapped on the cooker cover 1, in which case, the baffle plate 2 seals the exhaust hole 11, thereby sealing the exhaust hole 11 by the baffle plate 2. In the second state, the baffle plate 2 opens the exhaust hole 11 under the pushing of steam in the electric cooker. In the first state, the baffle plate 2 can isolate the outside from the space in the electric cooker body 7.
It should be noted that, the cooker cover 1 in this embodiment refers to a cover, the electric cooker further includes an inner cover 8, the cover is covered outside the inner cover 8, the cooker cover 1 (i.e. the cover) and the inner cover 8 together form the electric cooker cover, the inner cover 8 is provided with an air outlet corresponding to the cover, and a sealing ring 9 is further provided between the inner cover 8 and the cover, and since the air exhaust assembly of the electric cooker provided in this embodiment mainly relates to the air exhaust hole on the cover, the air outlet on the inner cover is not excessively introduced, which is the prior art, and detailed description thereof is not repeated herein.
Through the structure, the opening degree of the exhaust hole 11 in the exhaust component of the electric cooker is automatically adjusted according to the steam pressure in the electric cooker. Specifically, when the pressure of steam in the electric cooker is high (for example, when porridge is cooked), the force of steam acting on the baffle plate 2 in the exhaust hole 11 is high, so that the baffle plate 2 is pushed to be opened to a greater extent against the gravity of the baffle plate 2, and the exhaust hole 11 in this case can discharge more steam in unit time; when the pressure of steam in the rice cooker is small (for example, when rice is cooked), the force of steam acting on the baffle plate 2 in the exhaust hole 11 is small, so that the baffle plate 2 is pushed to be opened to a smaller extent by overcoming the gravity of the baffle plate 2, and the exhaust hole 11 in this case can exhaust less steam per unit time.
Therefore, the electric cooker using the electric cooker exhaust assembly can keep higher temperature in the cooker body 7 when cooking, the degree of opening the exhaust hole 11 by the baffle plate 2 is small, so that micro-pressure can be carried out on rice, the probability of cooking and clamping is lower, when porridge is cooked, the degree of opening the exhaust hole 11 by the steam pushing the baffle plate 2 is larger, as more steam is discharged from the exhaust hole 11, the probability of overflowing porridge liquid is lower, in addition, when heat preservation is needed after cooking, the steam pressure in the cooker body 7 is small, the baffle plate 2 is insufficient to seal the exhaust hole 11 so as to play a better heat preservation effect, and in addition, when the electric cooker is not used, the baffle plate 2 is lapped on the cooker cover 1 under the action of self gravity, the baffle plate 2 seals the exhaust hole 11, and thus external dust and insects are prevented from entering the cooker body 7.
Alternatively, the shape of the baffle 2 in the present embodiment may be square, circular, or the like. Of course, the exhaust hole 11 in the present embodiment may be a square hole, a circular hole, or the like. In this embodiment, the shape of the baffle plate 2 is square, and the exhaust hole 11 is a square hole.
An alternative implementation of this embodiment is as follows: the square-shaped baffle plate 2 is divided into two sections, such as a first section and a second section, by the hinge shaft, the first section and the second section being located on both sides of the hinge shaft, respectively. The first section is larger in size than the second section.
A first inclined surface 21 is provided at the edge of the baffle plate 2, and the first inclined surface 21 is located at the edge of the first section, specifically, the first inclined surface 21 is provided at each edge of the first section of the baffle plate 2. A second inclined surface 12 for engaging the first inclined surface 21 is provided on a wall of the exhaust hole 11, and specifically, the second inclined surface 12 is provided on each wall of the exhaust hole 11 corresponding to the first section. In the first state, the first inclined surface 21 overlaps the second inclined surface 12. By utilizing the cooperation of the first inclined plane 21 and the second inclined plane 12, in the process of opening and closing the exhaust hole 11 by the baffle plate 2, no friction exists between the outer side wall of the baffle plate 2 and the wall of the exhaust hole 11, the movement of the baffle plate 2 is smoother, the blocking of the movement of the baffle plate 2 is prevented, and when the first inclined plane 21 and the second inclined plane 12 are attached (namely, when in the first state), the attached first inclined plane 21 and second inclined plane 12 can play a better sealing effect.
In the first state, the first inclined surface 21 is overlapped with the second inclined surface 12, so that the stop is overlapped with the pot cover 1.
An alternative implementation of this embodiment is as follows: an outwardly convex arc surface 22 is also provided at the edge of the second section of the baffle plate 2 (i.e. the other side of the hinge shaft). The wall of the exhaust hole 11 is provided with a concave cambered surface 13 corresponding to the convex cambered surface 22. When the baffle plate 2 is hinged on the cooker cover 1 through a hinge shaft, the outer convex cambered surface 22 on the baffle plate 2 is rotationally wrapped in the inner concave cambered surface 13. Like this, the cooperation of evagination cambered surface 22 and indent cambered surface 13 not only makes baffle 2 can rotate along the place on above-mentioned a kind of deep pot lid 1, carries out normal running fit through very little clearance between evagination cambered surface 22 and the indent cambered surface 13 moreover to be difficult to get into the spot such as dust in the clearance between evagination cambered surface 22 and the indent cambered surface 13, thereby realize not ponding, not hiding dirty effect at the articulated shaft opposite side.

Thus, when the outer arc surface 22 rotates to a certain angle in the inner arc surface 13, the surface of the baffle plate 2 contacts with the limiting structure 14. Alternatively, the limiting structure 14 in this embodiment is actually an end chamfer of the concave cambered surface 13 described above. In addition, by setting the dimension length of the above-mentioned limit structure 14 above the baffle plate 2, the maximum openable angle of the baffle plate 2 can be set, for example, the dimension of the upper limit structure 14 above the baffle plate 2 is set to be shorter, and the maximum openable angle of the baffle plate 2 at this time is larger; the limit structure 14 is dimensioned longer above the flap 2, and the maximum angle at which the flap 2 can be opened is smaller.
In this embodiment, the size of the limit structure 14 above the baffle 2 is set such that the rotation angle of the baffle 2 is greater than 60 ° and less than 90 ° when the baffle 2 rotates to contact with the limit structure 14, that is, the maximum openable angle of the baffle 2 is between 60 ° and 90 ° (excluding 60 ° and 90 °). For example, the maximum openable angle of the shutter 2 is 65 °, 75 °, 80 °, 85 °, or the like.
It is easily understood that when the maximum openable angle of the baffle 2 is 75 deg., it means that the baffle 2 can be opened by steam in the pot 7 over an angle ranging from 0 to 75 deg..
Thus, the opening degree of the baffle plate 2 can be automatically adjusted within a certain angle range when the steam pressure changes. Specifically, the total weight of the baffle plate 2 is unchanged, the pressure of the steam acting on the baffle plate 2 is changed, the force of the steam acting on the baffle plate 2 is upward, and the gravity of the baffle plate 2 is downward, so that when the pressure of the steam on the baffle plate 2 is changed, the baffle plate 2 automatically rotates to automatically adjust the opening degree of the exhaust hole 11.
Moreover, the maximum opening angle of the baffle plate 2 is limited to be smaller than 90 degrees, so that the baffle plate 2 can automatically fall back towards the exhaust hole 11 under the action of the gravity of the baffle plate 2 when the acting force of steam is small.
Alternatively, the weight of the baffle 2 in this embodiment is 1g-10g, e.g. the weight of the baffle 2 is 1g, 2g, 3g, 4g, 5g, 6g, 7g, 8g, 9g, 10g, etc., to ensure that the steam inside the pot 7 can push the baffle 2 open.
An alternative implementation of this embodiment is as follows: the edge of the baffle 2 is provided with two opposite convex plates 3, the convex plates 3 are positioned close to the end wall of one end of the baffle 2, in the embodiment, the hinge shaft comprises two coaxial round shafts 4, each convex plate 3 is provided with a round shaft 4, the bottom wall of the pot cover 1 is provided with two opposite lug plates 5, each lug plate 5 is positioned at the lower opening edge of the exhaust port, the lug plates 5 are provided with round holes 51, and the two round shafts 4 are respectively and rotatably inserted into the two round holes 51, so that the baffle 2 is hinged on the pot cover 1. By this structure, the baffle plate 2 is completely positioned in the exhaust hole 11 in the first state, and the exhaust hole 11 is better sealed by the cooperation of the first inclined surface 21 and the second inclined surface 12 and the cooperation of the convex cambered surface 22 and the concave cambered surface 13.
