Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and in particular relates to a pressure cooking device. Background Art

[0002] A pressure cooking appliance generally comprises a lid and a pot body. According to the assembly method of the lid and the pot body, the pressure cooking appliance can be divided into a one-piece type and a two-piece type. The lid and the pot body of the one-piece pressure cooking appliance are hinged so that the lid can be rotated around the hinge to open and close the lid. The lid of the two-piece pressure cooking appliance can be removed from the pot body to open and close the edge of the pot body.

[0003] For split-type pressure cooking appliances, in order to ensure pressure cooking in a safe environment, a micro switch is usually provided on the pot body and a trigger rib is provided on the pot lid. When the pot lid covers the pot body and is locked with the pot body, the trigger rib triggers the micro switch, and pressure cooking can be performed at this time.

[0004] However, with the development of technology, more and more pressure cooking appliances are equipped with the function of cooking with the lid open, that is, cooking can be performed in the open lid mode without closing the lid. During the cooking process, the storage and placement of the lid becomes a more difficult problem for users. In actual use, various problems arise due to improper lid placement or misoperation.

[0005] For example, if the pot lid is not stored on the pot body, but the pot lid is simply placed on the pot body, the pot mouth of the pot body is blocked, but the lid is not closed. If the pot lid is placed in this way, when the liquid in the pot boils, the pot mouth is blocked by the pot lid. As the water vapor in the pot increases, the pressure in the pot gradually rises, and the upward thrust on the pot lid gradually increases, so the pot lid will jump on the pot body and make a sound. For another example, if the pot lid is placed on the pot body and the lid is slightly closed, the cover teeth of the pot lid are partially engaged with the pot teeth of the pot body, but not completely engaged. At this time, use the open lid cooking function to heat. If thick soups, porridge and other ingredients are cooked in the pot, and the liquid in the pot boils, the ingredients block the float, and the water vapor cannot be discharged at this time, and the pressure in the pot gradually increases. When the pressure in the pot increases to a certain level, there is a risk of the lid collapsing. Utility Model Content

Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0048] like Figures 1 to 11 As shown, a pressure cooking device comprises a pot body 1 and a pot cover 2 which is removably placed on the pot body 1, a receiving position 12 for accommodating the pot cover 2 is provided on one side of the pot body 1, the pot body 1 is provided with a detection member 3, and the pot cover 2 is provided with a trigger assembly 4, and when the pot cover 2 is opened and placed in the receiving position 12, the trigger assembly 4 triggers the detection member 3.

[0049] Specifically, the pressure cooking device has an open-lid cooking state. When the trigger component 4 triggers the detection element 3, the pressure cooking device receives a signal and can operate in the open-lid cooking state. The open-lid cooking state can be open-lid cooking, open-lid steaming, etc., which are not limited here.

[0050] The pressure cooking device of the present invention is provided with a receiving position 12 on one side of the pot body 1. When the pot cover 2 is removed from the pot body 1, the pot cover 2 can be placed in the receiving position 12 to achieve simple storage of the pot cover 2, thereby solving the user's troubles in storing the pot cover 2 and avoiding the problem of placing the pot cover 2 on a countertop, resulting in occupying a large space and contaminating the countertop.

[0051] The pot body 1 is provided with a detection member 3, and the pot cover 2 is provided with the trigger assembly 4. When the pot cover 2 is placed in the accommodation position 12, the trigger assembly 4 triggers the detection member 3, so that the pressure cooking device obtains a signal that the pot cover 2 is placed in the correct position, so that the pressure cooking device can cook in the open-cover cooking mode. When the pot cover 2 is not placed in the accommodation position 12, the detection member 3 has no signal, and the pressure cooking device cannot operate in the open-cover cooking mode. In this way, the placement position of the pot cover 2 is detected by the detection member 3, and is associated with the cooking program of the pressure cooking device, so as to further standardize the use of the user, ensure that the user places the pot cover 2 in a preset position for open-cover cooking, and at the same time, when the pot cover 2 is stored in the accommodation position 12, it avoids the pot mouth, so that the steam in the pot can be discharged smoothly, and the safety of the open-cover cooking process is also ensured, and the risk of the pot cover 2 jumping or bouncing is reduced.

[0052] It is understandable that the arrangement of the detection member 3 and the trigger assembly 4 regulates the placement of the pot cover 2 by the user in the open state, and guides the user to place the pot cover 2 in a preset position when using the open-lid cooking function, so as to ensure the safety of the cooking process. For example, if the user covers the pot cover 2 on the pot body 1 to block the pot mouth, or places the pot cover 2 directly on the countertop, the detection member 3 cannot be triggered by the trigger assembly 4, and the pressure cooking device cannot perform the open-lid cooking function. Only when the user removes the pot cover 2 from the pot body 1 and places it in the accommodation position 12, the trigger assembly 4 can trigger the detection member 3, and open-lid cooking can be performed at this time.

[0053] In a preferred embodiment, Figures 8 to 11As shown, the pressure cooking device has a lid-closed cooking state and a lid-open cooking state, and the trigger assembly 4 includes a first trigger member 41 and a second trigger member 42. When the pot cover 2 covers the pot body 1, the first trigger member 41 triggers the detection member 3 to enable the pressure cooking device to operate in the lid-closed cooking state. When the pot cover 2 is placed in the accommodating position 12, the second trigger member 42 triggers the detection member 3 to enable the pressure cooking device to operate in the lid-open cooking state.

[0054] The pot cover 2 is provided with a first triggering member 41 and a second triggering member 42 at different positions. The first triggering member 41 and the second triggering member 42 can respectively trigger the detection member 3 when the pot cover 2 is in different states, so that the detection member 3 can detect different states of the pot cover 2, so that the pressure cooking device can operate in different cooking modes according to the states of the pot cover 2. When the pot cover 2 covers the pot body 1, the first triggering member 41 triggers the detection member 3, indicating that the pot cover 2 has been covered in place, and the cover teeth 21 on the pot cover 2 and the pot teeth 11 on the pot body 1 are fully engaged, and pressure cooking can be performed at this time. When the pot cover 2 is removed from the pot body 1 and placed in the accommodating position 12, the second triggering member 42 triggers the detection member 3, indicating that the pot cover 2 has been opened and placed in the correct position, and cooking with the lid open can be performed at this time.

[0055] It should be noted that the present embodiment does not limit the number of the detection member 3. In one embodiment, there is one detection member 3, and the first trigger member 41 and the second trigger member 42 act on the detection member 3. For example, the first trigger member 41 and the second trigger member 42 are arranged at different positions, and both correspond to the same detection member 3. When the pot cover 2 is in the closed state, the first trigger member 41 triggers the detection member 3, and the detection member 3 outputs a first signal. When the pot cover 2 is in the storage position, the second trigger member 42 triggers the detection member 3, and the detection member 3 outputs a second signal. The control unit of the pot body 1 identifies different states of the pot cover 2 according to the different signals output by the detection member 3, so as to control the switching of the corresponding cooking mode.

[0056] In another embodiment, if Figures 4 to 7 As shown, there are two detection members 3 , and they are arranged in one-to-one correspondence with the first trigger member 41 and the second trigger member 42 .

[0057] In this embodiment, the first trigger member 41 corresponds to one of the detection members 3, and the second trigger member 42 corresponds to one of the detection members 3. When the pot cover 2 is in the closed state, the first trigger member 41 triggers the corresponding detection member 3, and when the pot cover 2 is in the storage position, the second trigger member 42 triggers the corresponding detection member 3. The control unit of the pot body 1 identifies different states of the pot cover 2 according to different signals output by different detection members 3, so as to control the switching of corresponding cooking modes.

[0058] In addition, since the first trigger member 41 and the second trigger member 42 correspond to one of the detection members 3 respectively and trigger them, the present embodiment does not limit the setting positions of the respective trigger members and the detection members 3, and it is only necessary to ensure that the trigger members are set correspondingly to the detection members 3 corresponding to them. For example, the first trigger member 41 can be set on the front side of the pot cover 2, and the corresponding detection member 3 is set on the front side of the pot body 1, and the second trigger member 42 is set on the rear side of the pot cover 2, and the corresponding detection member 3 is set on the rear side of the pot body 1. For another example, the first trigger member 41 and the second trigger member 42 are both set on the rear side of the pot cover 2, and the two detection members 3 are also set on the rear side of the pot body 1.

[0059] Specifically, Figure 5 , Figure 6 , Figure 7 As shown, the trigger assembly 4 and the detection member 3 are fixed in the same manner, a fixing groove 14 for placing the trigger assembly 4 is provided inside the pot cover 2, and a fixing groove 14 for placing the detection member 3 is also provided inside the pot body 1, and a screw hole is adjacently provided on one side of the fixing groove 14. After the trigger assembly 4 and the detection member 3 are placed in the fixing groove 14, a screw is screwed into the screw hole so that the screw forms a limit on the trigger assembly 4 and the detection member 3 in the fixing groove 14 to prevent them from falling out of the fixing groove 14.

[0060] It should be noted that the present invention does not limit the manner in which the trigger component 4 triggers the detection member 3, that is, the detection manner of the detection member 3, which can be one of the following embodiments:

[0061] Embodiment 1: In this embodiment, the detection member 3 includes a detection part and a sensing part, and the sensing part can move relative to the detection part. When the pot cover 2 is placed in the accommodating position 12, the trigger assembly 4 pushes the sensing part to move to trigger the detection part.

[0062] In this embodiment, the detection member 3 realizes detection by contact, and the trigger component 4 needs to contact the sensing part and push the sensing part to move so that it triggers the detection part to realize contact triggering and improve the reliability of detection.

[0063] For example, the detection member 3 can be a micro switch, the sensing part can be a sensing rod protruding from the surface of the pot body 1, and the trigger component 4 can be a trigger protrusion protruding from the surface of the pot cover 2. When the pot cover 2 is placed in the accommodating position 12, the trigger protrusion pushes the sensing rod to trigger the micro switch.

[0064] Embodiment 2: In this embodiment, the detection member 3 is an electromagnetic induction element with a sensing range, the trigger component 4 includes a magnetic member, and when the pot cover 2 is placed in the accommodating position 12, the trigger component 4 is located within the sensing range to trigger the detection member 3.

[0065] The triggering member can be triggered by the detecting member 3 without contact, so that the setting positions of the detecting member 3 and the triggering member are more flexible and the sensing is more sensitive. The detecting member 3 can be arranged inside the pot body 1 and the triggering member can be arranged inside the pot cover 2 without being exposed to the outside, thereby avoiding the problem that the triggering member or the detecting member 3 is contaminated and affects the sensing sensitivity and accuracy.

[0066] It can be understood that the magnetic member has a magnetic field. When the detection member 3 is located in the magnetic field of the magnetic member, the detection member 3 is triggered under the action of the magnetic force.

[0067] Furthermore, this embodiment does not limit the type of the detection element 3, which can be one of the following embodiments:

[0068] The magnetic member includes a first trigger member 41 and a second trigger member 42 .

[0069] Embodiment 1: In this embodiment, the magnetic poles of the first trigger member 41 and the second trigger member 42 facing the detection member 3 are different, so that the magnetic member generates magnetic fields with different magnetic poles at the detection member 3, and the detection member 3 can detect the polarity of the magnetic field. Preferably, the detection member 3 is a Hall element, which can distinguish the polarity of the magnetic member. For example, the side of the first trigger member 41 facing the detection member 3 is the S pole, and the side of the second trigger member 42 facing the detection member 3 is the N pole. When the pot cover 2 is in the closed state, the first trigger member 41 enters the sensing range of the detection member 3, and the detection member 3 recognizes the S pole and outputs a first signal. When the pot cover 2 is in the storage position, the second trigger member 42 enters the sensing range of the detection member 3, and the detection member 3 recognizes the N pole and outputs a second signal. The control unit of the pot body 1 identifies the different states of the pot cover 2 according to the different signals output by the detection member 3, so as to control the switching of the corresponding cooking mode.

[0070] Embodiment 2: In this embodiment, the first trigger member 41, the detection member 3, and the pot lid 2 have a closed position and a storage position placed in the accommodating position 12. In the closed position, the first trigger member 41 is located within the sensing range. In the storage position, the second trigger member 42 is located within the sensing range. Preferably, the detection member 3 is a reed switch. When the pot lid 2 is in the closed state, the first trigger member 41 enters the sensing range of the detection member 3, and the detection member 3 outputs a first signal. When the pot lid 2 is in the storage position, the second trigger member 42 enters the sensing range of the detection member 3, and the detection member 3 outputs a second signal. The control unit of the pot body 1 identifies different states of the pot lid 2 according to different signals output by the detection member 3, so as to control the switching of corresponding cooking modes.

[0071] Of course, two or more signal outputs can also be realized according to the strength of the magnetic field sensed by the detection member 3, so as to meet the detection of the pot cover 2 in the closed and stored states, or to detect more positions of the pot cover 2. For example, in the closed position, the first trigger member 41 triggers the detection member 3 alone, and the detection member 3 outputs a first signal. In the stored position, the second trigger member 42 triggers the detection member 3 alone, and the detection member 3 outputs a second signal. When the pot cover 2 is in a certain position, the first trigger member 41 and the second trigger member 42 trigger the detection member 3 together, and the detection member 3 outputs a third signal, so that the control unit has more options.

[0072] As a preferred embodiment of the present invention, Figure 2 , Figure 3As shown, a laterally protruding fixing rib 121 is provided on one side of the pot body 1 to form the accommodating position 12, and a plug-in groove 122 is opened on the fixing rib 121. A laterally protruding plug-in rib 22 is provided on the circumference of the pot cover 2, and the plug-in rib 22 is plugged into and matched with the plug-in groove 122 to accommodate the pot cover 2.

[0073] The fixing rib 121 protrudes laterally from one side of the pot body 1, so that after the pot cover 2 is placed in the accommodation position 12, it is located on one side of the pot body 1 as a whole, thereby avoiding the pot mouth, which not only allows the steam in the pot to be discharged smoothly to avoid the pressure in the pot from increasing, but also reduces the contact between the steam gushing out of the pot and the pot cover 2, and liquefies on the pot cover 2 to form condensed water, thereby ensuring the cleanliness of the pot cover 2. The pot cover 2 is provided with a plug-in convex rib 22 on the circumference, and the plug-in convex rib 22 is inserted into the plug-in groove 122 from top to bottom, so that the pot cover 2 is placed upright in the accommodation position 12 as a whole, which is convenient for users to take and put. In addition, the plug-in method can not only achieve simple fixation and facilitate taking and putting, but also ensure the stability of the pot cover 2 by leaning on the fixing rib 121 under the action of its own gravity, thereby reducing the shaking of the pot cover 2.

[0074] Specifically, Figure 8 , Fig. 9 , Fig.10 , Fig.11 As shown, the trigger assembly 4 includes a first trigger member 41 and a second trigger member 42. The first trigger member 41 is arranged close to the bottom wall of the pot cover 2 to trigger the detection member 3 when the cover is in the closed position. The second trigger member 42 is arranged inside the plug-in rib 22. When it is matched with the plug-in slot 122, it is closer to the detection member 3 and triggers the detection member 3. At this time, the first trigger member 41 is far away from the detection member 3 and cannot trigger the detection member 3.

[0075] Furthermore, if Figure 3 As shown, the fixed rib 121 extends outward and upward from the edge of the pot body 1. The top surface of the fixed rib 121 has a supporting surface 123, and the fixed rib 121 extends obliquely so that there is an angle between the supporting surface 123 and the horizontal plane. After the plug-in rib 22 is plugged into the plug-in groove 122, the fixed rib 121 not only provides an upward supporting force for the pot cover 2, but also because the supporting surface 123 is inclined upward, the supporting force of the fixed rib 121 on the pot cover 2 is also inclined upward, thereby generating vertical and horizontal force components, so that the pot cover 2 leans on the fixed rib 121, and the stability of the pot cover 2 is improved. At the same time, the shear force on the plug-in rib 22 can be reduced, and the risk of deformation or damage of the plug-in rib 22 can be reduced.

[0076] Preferably, if Figure 1 As shown, the pot body 1 has a front side, a rear side, and sides located on the left and right sides, and the fixing ribs 121 are arranged on the rear side or the sides.

[0077] When the user removes the pot cover 2 from the pot body 1, the pot cover 2 can be plugged into the fixed ribs 121. The fixed ribs 121 are located on the rear side, that is, the side away from the user, so that the front side of the pot body 1 is an open space, which is convenient for the user to serve rice or take and put food. In another embodiment, the fixed ribs 121 are located on the side, so that when the user places the pot cover 2, the arm does not need to cross the pot mouth to reach the back side, and the pot cover 2 can be plugged into the fixed ribs 121, thereby preventing the steam gushing out of the pot from contacting the user's hand, thereby improving the user experience.

[0078] As a preferred embodiment of the present invention, Figure 3 As shown, the top of the pot body 1 is provided with a water collecting groove 13 surrounding the pot mouth, the pot cover 2 includes a surface cover and an inner cover located at the lower side of the surface cover, the edge of the inner cover has a cover tooth 21 protruding toward the pot body 1, and when the pot cover 2 is placed in the accommodating position 12, the projection of the cover tooth 21 toward the pot body 1 is located in the water collecting groove 13.

[0079] It is understandable that the pot cover 2 is placed upright on one side of the pot body 1. Although it avoids the pot mouth, during the cooking process with the lid open, the steam in the pot will still reach the pot cover 2, and then form condensation water on the surface of the pot cover 2 facing the pot body 1.

[0080] The cover teeth 21 are arranged to protrude toward the pot body 1 so as to be conveniently engaged with the pot teeth 11 of the pot body 1. When the pot cover 2 is placed upright at the accommodation position 12, the cover teeth 21 protrude toward one side of the pot body 1, so that the condensed water on the pot cover 2 facing the side of the pot body 1 will flow to the cover teeth 21. The projection of the cover teeth 21 is located in the water collecting groove 13, so that the condensed water on the pot cover 2 will directly drip from the cover teeth 21 into the water collecting groove 13 and be collected. This ensures the cleanliness of the countertop, reduces the cleaning pressure of the user, and improves the user experience.
