Description

Electric cooker and lid

The invention relates to an electric cooker and a lid, in particular to an electric cooker and a pot lid which can be used for cooking ingredients.

According to the new patent of the Republic of China Patent Publication No. M464107, an "automatic electric quick cooker" is disclosed, which comprises a casing, a middle pot, a heating device, a lid, a pressure relief valve and a fastener to achieve a faster cooking speed and Energy saving and other effects. However, the disclosed pressure relief valve can be used for steam discharge in the pot. However, due to insufficient locking ability of the elastic piece, the air outside the pot easily enters the pot through the elastic piece, which is actually difficult to make in the pot. Maintaining a vacuum and having a better internal pressure results in a limited effect of rapid cooking and energy conservation.

According to the new patent of the Republic of China Patent No. M414178, a "heat-dissipating structure of the pot" is disclosed, including a body, a snorkel, a valve seat, and a ball. When the vapor pressure in the pot is large enough, the ball can be pushed. Ascending, the superheated vapor is discharged through the vent pipe. However, the ball is loaded on the snorkel with its own weight. Although the ball will fall after the overheated vapor is leaked and then plug the upper end of the snorkel, the pressure difference between the inside and the outside of the pot causes the lid to be adsorbed on the pot. Because the pressure can not be balanced by external force, the pressure difference can be balanced. Therefore, it is only possible to apply a large force to the lid or use a swaying tool to remove the lid, which causes inconvenience in use.

According to the new patent of the Republic of China Patent Publication No. M338602, a "pot sealing structure" is disclosed, which includes a body, an elastic member and a valve body. After cooking the food, the valve body is sealed by the elastic element to seal the vent hole, and the lid is adsorbed on the pot due to the pressure difference between the inside and the outside of the pot. In the above, although the pressure difference can be balanced by pushing the valve body through the pointed object, if the sharp object is needed and cannot be found by being lost or randomly littered, the pot cover must be exerted with a large force. Or use the swaying tool to remove the lid, which is still inconvenient in use.

The main object of the present invention is to solve the above problems and provide an electric cooker and a pot cover. The plug provided by the pressure relief valve plugs the through hole in the valve body, and can be applied to the operating portion of the valve body. The force is deformed to allow the plug of the through hole to be displaced to form a gap through which the gas can pass, thereby achieving the convenience of the pressure relief operation.

For the purpose of the present invention, the present invention comprises: a pot body having an opening space facing upwardly, and having a pair of heaters for heating the accommodating space; a cover body covering the opening of the pot body a grip having a joint fixed to the cover, and a grip portion extending laterally from the joint; a pressure relief valve having a valve body and a plug member of a soft material, The valve body has a hollow chamber, and a through hole penetrating downwardly of the cover body is communicated at a bottom portion of the hollow chamber, and an outwardly communicating vent hole is arranged around the hollow chamber, and the pressure relief valve is fixed by the valve body In the joint portion, an operation portion that can be biased by a finger to deform the valve body is exposed at the joint portion, and the plug member is disposed in the hollow chamber to plug the through hole, and the plug member is formed in the pot body. When the steam is pushed open or when the operating portion is deformed by the force, the gap through which the gas can pass is formed.

Wherein the plug member has a rod body and has a plug portion at a bottom end of the rod body, the valve body has a top wall at a top thereof, the rod body top end passes through the top wall, and the top wall is The upper and lower sides respectively have an upper stop portion and a lower stop portion to limit the stroke of the upper and lower displacement of the rod body. The rod body can interlock the plug portion when the operating portion is biased to form the gap.

Wherein, the plug portion tapers conically away from the rod body, and is inserted into the through hole at the top of the through hole.

Wherein, the hollow chamber in the valve body has a conical section which is tapered in the lower section and has an inner diameter downward. The inner diameter of the bottom of the conical section is reduced to be in line with the top of the through hole, and the plug is rounded. The through hole is plugged at the bottom of the conical section.

The fixing portion is fixed at a position of the cover body, and a fixing member passes through the bottom of the cover body to lock the joint portion to the cover body, and the joint portion has a top end of the fixing member a bottom pocket, the valve body being located in the recess with a base at the bottom thereof fixed to the top of the fixing member.

The grip 3 has a joint portion 31 fixed to the lid body 2, and the grip 3 extends laterally from the joint portion 31. Hold 32.

As shown in FIGS. 2 to 3, the pressure relief valve 4 has a valve body 5 of a soft material and a plug member 6, the valve body 5 having a hollow chamber 51, and communicating with the cover at the bottom of the hollow chamber 51. a through hole 52 penetrating below the body 1 and a venting hole 53 communicating outwardly around the hollow chamber 51. The pressure relief valve 4 is fixed to the joint portion 31 by the valve body 5, and at the joint portion 31 An operation portion 54 that is biased by a finger to deform the valve body 5 is exposed, and the plug member 6 is provided in the hollow chamber 51 to plug the through hole 52.

In the present embodiment, the hollow chamber 51 in the valve body 5 has a conical section 511 which is tapered in the lower section and has an inner diameter downward. The inner diameter of the bottom of the conical section 511 is reduced to the top of the through hole 52. Consistent and connected. In addition, the fixing portion 31 is fixed at the position of the cover body 2, and a fixing member 33 is attached from the cover body. The bottom of the 2 is passed through to lock the joint portion 31 to the cover body 2. The joint portion 31 has a recess 311 which is defined by the top end of the fixing member 33. The valve body 5 has a base at the bottom thereof. 55 is fixed to the top of the fixing member 33 and located in the recess 311.

As shown in FIG. 3, the plug member 6 of the present embodiment has a rod body 61 and has a plug portion 62 at the bottom end of the rod body 61. The valve body 5 has a top wall 56 at the top thereof. The top end of the body 61 passes through the top wall 56, and has an upper stop portion 63 and a lower stop portion 64 on the upper and lower sides of the top wall 56 to limit the stroke of the rod body 61 up and down. Here, the plug portion 62 tapers conically in a direction away from the rod body 61, and is inserted into the through hole 52 at the top of the through hole 52.

As shown in Fig. 3, when the pot body 1 is cooked under the cover of the lid body 2, the inside of the pot body 1 is heated by steam for a period of time and the pressure is gradually increased, and the valve body 5 is plugged at this time. The plug member 6 of the hole 52 is pushed away by the aforementioned steam to form a slit A (a gap formed when the plug member 6 is drawn up by a broken line), and a high-pressure steam is formed in the pot body 1 to pass through the slit A. After passing through the accommodating space 11, the vent hole 53 is discharged to maintain the proper pressure in the pot body 1 to facilitate the acceleration of the cooking of the food. When the ingredients are cooked and the pot is to be cooked, the pot body 1 is placed under the cover of the lid body 2, and there is still a slight pressure difference between the inside and the outside of the pot body 1, and the user can use the tool without using any tools. As shown in Fig. 4, only the finger is biased to the operating portion 54 to deform the valve body 5 to displace the plug member 6. The plug portion 62 is displaced at the top end of the through hole 52 after the plug member 6 is displaced. In the gap B, the gas can be circulated by the generation of the gap B, and the pressure difference can be eliminated. At this time, the lid body 2 can be easily opened due to the pressure balance inside and outside the pot body 1.

From the above description, it is not difficult to find that the present invention has the advantage that the plug hole 6 provided in the pressure relief valve 4 is inserted into the through hole 52 in the valve body 5, so that the accommodation space 11 of the pot body is kept closed. The plug member 6 can be pushed open to expose the gap A when the high-pressure steam is generated in the accommodating space 11, so as to relieve the excessively high vapor pressure in the accommodating space 11, and the cover body 2 to be opened is in the pot body. When the pressure difference between the inside and the outside is absorbed, the user can simply apply force to the operating portion of the valve body 5 to deform the finger, and plug the through hole 52. The displacement of the member 6 to form a slit B through which the gas can pass can achieve the convenience of the pressure relief operation, and the cover body 2 can be easily taken away from the body 1.

Of course, there are many examples of the invention, with only minor variations in the details. Referring to Figures 5 to 7, which are a second embodiment of the present invention, which differs from the first embodiment in that the plug member 6A is spherical and plugs the through hole 52 at the bottom of the conical section 511. . As shown in Fig. 5, when steam is formed in the accommodating space 11 due to heating and the pressure is gradually increased, the plug member 6A is also pushed away by the steam to form the slit A (when the plug 6A drawn by the broken line is moved up) Further, as shown in FIGS. 6 to 7, when the cover body 2 is to be opened, the operation portion 54 of the valve body 5 is kneaded to deform the through hole and the plug member 6A simultaneously. The movement is made to form the slit B, whereby the convenience of the pressure relief operation can be achieved, and the lid body 2 can be easily taken out of the pot body 1 to achieve the same effect as the first embodiment.

The above description of the embodiments is intended to be illustrative of the invention and is not intended to limit the scope of the invention.
