Description

Technical Field

[0001] The utility model relates to the field of cookware, in particular to a split cookware. Background Art

[0002] In a family kitchen, electric cooking machines such as electric pressure cookers and electric rice cookers are common kitchen appliances. The electric cooking machines in the prior art are shown in a structure of an electric cooking machine in Chinese patent literature, patent number: CN201510084586.9, which mainly includes a pot body, a pot core and a pot cover that can be fixedly connected to the pot core. An electric heating device is installed inside the pot body, and the heating part of the electric heating device is in contact with the bottom of the pot core. A pressure sensing device is provided in the pot cover, and an electromagnetic exhaust valve is installed on the pot cover. The pressure sensing device is electrically connected to the electromagnetic exhaust valve, and the pot cover is plug-in connected to the pot body through an electric plug structure.

[0003] In the above-mentioned prior art, since power supply and signal communication are required simultaneously during the use of the pressure sensing device and the electromagnetic exhaust valve, the pot lid and the pot body are connected using an electric plug structure such as the prior art patent number: CN202221045885.3. The electric plug has an N pole, an L pole and a ground wire for power supply, and has D1 and D2 data terminals for signal communication. Therefore, when the pot is placed on the pot body, in order to achieve electrical coupling between the pot lid and the pot body, there is only one placement angle, and in order to meet the power supply and communication requirements, the N pole, L pole, ground wire, D1 and D2 data all require independent physical connections, which increases the complexity of the logical connection and reduces production efficiency.

[0004] If the electric plug of this structure is not used for power supply and signal communication, the pot cover can only be hinged on the pot body or the pot inner body, and the power line or the signal line is passed through the hinge to be electrically connected to the electrical components on the pot cover. Alternatively, wireless power supply and wireless communication can be used, but this method will increase the production cost. Therefore, a split cookware is needed to solve the above-mentioned existing problems for consumers to choose. Summary of the invention

[0031] The utility model is further described below in conjunction with the accompanying drawings and embodiments. Embodiment 1:

[0032] like Figures 1 to 3 As shown, a split cooker comprises:

[0033] A base 1, wherein a conductive ring 11 is disposed on the base 1, and the conductive ring 11 forms a receiving surface 12 on the top surface of the base 1, and a conductive contact 13 is disposed on the receiving surface 12;

[0034] The metal pot 2 is placed on the receiving surface 12 in a split manner, and the bottom of the pot touches the conductive contact 13 to form a first electrical connection branch.

[0035] The electrical part 3 is fixed on the metal cookware 2, and a conductive contact 31 is provided at the bottom of the electrical part 3, and the conductive contact 31 abuts against the conductive ring 11 and forms a second electrical connection branch;

[0036] The electrical part 3 is provided with an electrical device 4, and two lead ends of the electrical device 4 are electrically connected to the conductive contact 31 and the metal cookware 2 respectively. The electrical device 4 forms an electrical circuit for both power supply and communication with the base 1 through a first electrical connection branch and a second electrical connection branch.

[0037] This split cookware uses the metal cookware 2 as a conductor, which forms an electrical connection branch when in contact with the conductive contact 13, and the electrical part 3 with the electrical device 4 on the metal cookware 2 uses the conductive contact 31 at the bottom to contact the conductive ring 11 to form another electrical connection branch, so that the metal cookware 2 can be placed on the base 1 at any angle, and the metal cookware 2 placed on the base 1 can be rotated at will during the power-on or communication process, and the electrical device 4 on the metal cookware 2 can still maintain electrical connection with the base.

[0038] The base 1 is provided with a host circuit, which includes a first PCB board 5, which is electrically connected to the conductive ring 11 and the conductive contact 13; the electrical part 3 is provided with a slave circuit, which includes a second PCB board 6, which is connected between the electrical device 4 and the first electrical connection branch and the second electrical connection branch; through the control of the first PCB board 5 and the second PCB board 6, a pair of circuits can simultaneously take into account the functions of power supply and communication;

[0039] The metal cookware 2 includes a metal pot body 21 and a pot cover 22, and the pot cover 22 is a split cover arranged in the pot mouth of the metal pot body 21; the electrical part 3 includes a pot connection module fixed on the side of the metal pot body 21 and a lid connection module fixed on the pot cover 22, the lid connection module is correspondingly connected and matched with the pot connection module, and the conductive contact 31 is arranged on the bottom surface of the pot connection module.

[0040] In this embodiment, the cooker is an electric pressure cooker, and the electrical device 4 is specifically a solenoid valve 41, which is arranged in the pot connection module, and is directly electrically connected to the conductive contact 31 through a line, and the movable valve core of the solenoid valve 41 movably extends above the pot connection module;

[0041] The cover connection module is provided with a pressure relief valve 9 connected to the inner cavity of the metal cookware 2 and a push rod 10 for controlling the on and off of the pressure relief valve 9. When in use, the solenoid valve 41 is energized and pushes the push rod 10 to drive the pressure relief valve 9 to operate to open the inner cavity of the metal cookware 2.

[0042] The base 1 is also provided with an electromagnetic heating coil 14 and a control panel 15. The electromagnetic heating coil 14 can utilize electromagnetic heating to heat the food in the metal pot 2, and the control panel 15 can give a signal to the electrical device 4. In the pressure cooker, the operation of the pressure relief valve 9 is controlled by the signal, so that the user's hands do not need to be close to the pressure relief valve 9, thereby avoiding hand scalding accidents.

[0043] like Figure 4 As shown, an opening 101 is provided on the bottom surface of the pot connection module, and the contact end of the conductive contact 31 extends out of the pot connection module through the opening 101. An elastic member seat 102 is connected to the conductive contact 31 in the pot connection module. The elastic member seat 102 is provided with a first elastic member 103 that abuts against the conductive contact 31. The conductive contact 31 elastically abuts against the conductive ring 11 through the first elastic member 103.

[0044] The first elastic member 103 can be a return spring or a spring. When the metal cookware 2 is placed on the base, the first elastic member 103 can ensure that the conductive contact 31 is in contact with the conductive ring 2. On the one hand, sufficient contact can be ensured, and on the other hand, the conductive contact 31 is prevented from lifting the metal cookware 2.

[0045] like Figure 5 As shown, the conductive contact 13 is arranged at the center of the placing surface 12, and the conductive contact 13 includes a metal shell 131, and the metal shell 131 is connected to a second elastic member 132, and the metal shell 131 elastically touches the bottom of the metal cookware 2 through the second elastic member 132; when the metal cookware 2 is placed on the base 1, the elastically moving metal shell 131 presses the conductive contact 13 downward, and utilizes the second elastic member 132 to make the metal shell 131 fully contact with the bottom of the pot, and prevent the conductive contact 13 from lifting the metal cookware 2.

[0046] A temperature sensing element 133 is fixedly disposed in the metal shell 131 . The temperature sensing element 133 moves elastically up and down with the metal shell 131 . The temperature sensing element 133 and the metal shell 131 together form a temperature sensing probe, so that the conductive contact 13 can simultaneously take into account the functions of conducting electricity and heat transfer and temperature sensing.

[0047] The second elastic member 132 may be a return spring or a spring.

[0048] The receiving surface 12 may be a positioning concave surface 1211 (refer to Figure 6 As described above, the positioning recess 121 is used to position the metal cookware 2, thereby ensuring that the metal cookware 2 and the conductive ring 11 remain concentric. After the metal cookware 2 is rotated arbitrarily, the conductive contact 31 can abut against the conductive ring 11.

[0049] The pot connection module includes a handle base 23 connected to the outer wall of the metal pot body 21, the handle base 23 is connected to the lower handle 24, and the conductive contact 31 is arranged on the bottom surface of the handle base 23; the cover connection module includes an upper handle 25, the upper handle 25 is arranged corresponding to the lower handle 24, and the pot cover 22 is locked at the pot mouth of the metal pot body 21 by buckling the upper handle 25 with the lower handle 24;

[0050] In this embodiment, the cooker is a pressure cooker, and the lower handle 24 can lift and place the metal pot body 21 alone, while the upper handle 25 can lift and place the pot cover 22 alone. When in use, the pot cover 22 is rotated to align the upper handle 25 and the lower handle 24 and then buckled and locked, so that the pot cover 22 is fixed at the pot mouth of the metal pot body 21 to form a sealed inner cavity, and the upper handle 25 and the lower handle 24 are connected to form a cooker handle assembly, so that the user can hold the upper handle 25 and the lower handle 24 with one hand to lift the entire metal cooker 2. Embodiment 2:

[0051] In the second embodiment, Figure 6As shown, the electrical device 4 is arranged in the cover connection module, the cover connection module is provided with an upper coupling member 7 electrically connected to at least one lead-out end of the electrical device 4, the pot connection module is provided with a lower coupling member 8 electrically contacting the upper coupling member 7, and the lower coupling member 8 is electrically connected to the conductive contact 31;

[0052] In this embodiment, the electrical device 4 can be other sensing elements or control modules or display panels. Therefore, the cover connection module is electrically connected to the pot connection module through the upper coupling member 7 and the lower coupling member 8, so that the pot cover 22 can be disassembled in a split manner for easy cleaning. The upper coupling member 7 and the lower coupling member 8 can be two electrical contacts. After the two lead-out ends of the electrical device 4 are introduced into the pot connection module, one of the lead-out ends is electrically contacted with the metal pot body 21. Alternatively, the pot cover 22 is a metal pot cover, and the metal pot cover is naturally electrically connected after being arranged on the metal pot body 21. At this time, the upper coupling member 7 and the lower coupling member 8 only need a single electrical contact. One lead-out end of the electrical device 4 is introduced into the pot connection module and electrically connected to the conductive contact 31, and the other lead-out end is directly electrically connected to the metal pot cover.

[0053] Based on the above structure, in the split cooker, Figure 7 As shown in the circuit diagram in FIG. 1 , the method for power supply and signal communication between the base 1 and the electrical device 4 includes the following process:

[0054] S1, circuit power supply process;

[0055] When the PTX of the host circuit is at a high level, the Q5 switch module and the Q4 switch module in the host circuit are turned on, so that the slave circuit load is powered;

[0056] The PRX of the host circuit is in a high-impedance state, and the level of the PRX communication port is clamped at 5V through D2, so that it is not affected by the voltage of the host circuit;

[0057] S2, circuit communication process;

[0058] a. Communication boot code: When the host circuit starts the communication, PTX sends a boot code, the slave circuit disconnects the load, releases the main circuit, and prepares for communication;

[0059] b. Energy storage and low-power operation: The C4 energy storage module in the slave circuit stores energy. The C4 energy storage module provides energy to the slave circuit to maintain its low-power operation;

[0060] c. Data transmission and level acceleration release: PTX starts to send data, and PRX accelerates the level release at the same time to increase the communication speed. When sending data, PTX will continue to intermittently charge the C4 energy storage module to extend the operation time of the slave circuit;

[0061] S3, communication feedback process;

[0062] a. When PTX completes data transmission, it controls the Q5 switch module and the Q4 switch module and disconnects the main circuit. At the same time, PRX enters the data receiving state and waits for feedback data sent by the slave circuit (such as EOC).

[0063] By utilizing the above communication method, the functions of power supply and signal communication can be taken into account on a pair of lines at the same time, which greatly saves the length of physical connections and multi-pole coupling structures, simplifies the complexity of logical connections, and has the advantages of small line voltage loss and high communication quality.

[0064] In addition, D1 and D2 in the host circuit and the slave circuit are voltage-stabilizing diodes, which are used to prevent the IO voltage from exceeding the rated voltage, thereby protecting the stability and safety of the circuit.

[0065] The above is a preferred embodiment of the utility model, which shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model.
