Description

Technical Field

[0001] This utility model relates to the field of food cooking equipment, and in particular to a slow cooker device. Background Technology

[0002] Slow cooking, a food preparation method introduced from abroad, involves placing food in a heat-resistant plastic bag, removing all air to create a vacuum, and then immersing it in a constant-temperature hot water solution (50°C to 80°C) for a predetermined time. This allows the food to slowly cook at the optimal temperature, releasing the maximum amount of monosodium glutamate (MSG), preserving its original flavor, texture, and nutritional value. The entire process can take anywhere from three to five hours to several days and nights, depending on the ingredients.

[0003] Existing slow cookers directly install electric heating elements and thermostats inside the slow cooker to slowly cook water and packaged food at low temperatures. After slow cooking, the packaged food is removed from the slow cooker and allowed to cool naturally before being placed back in. This method has the following problems: workers are at risk of burns when removing or placing packaged food because the water in the slow cooker is still warm; the natural cooling of packaged food is slow; and the water in the slow cooker is not stirred, resulting in uneven temperature distribution. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned problems in the existing technology and provide a slow cooker device.

[0005] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0006] A slow cooker device, comprising:

[0007] The slow cooker is a rectangular box-shaped structure with an open top. The rear side of the slow cooker is provided with a hot water inlet, a cold water inlet, and a cold water outlet that are connected to the inner cavity of the slow cooker. The bottom of the slow cooker is provided with a hot water outlet that is connected to the inner cavity of the slow cooker. An integrated temperature sensor for monitoring the temperature inside the slow cooker is installed on the rear side of the slow cooker. Multiple ultrasonic transducers are installed on the bottom of the slow cooker.

[0008] The inner pot is a rectangular box-shaped structure with an open top. Several water passage holes are opened on the side wall and bottom of the inner pot. Multiple rectangular grid plates are stacked in the inner pot from bottom to top.

[0009] A rectangular lid that covers the top opening of the slow cooker.

[0010] Furthermore, it also includes a control cabinet, which houses a PLC controller, an ultrasonic generator, a first relay, a second relay, a third relay, and a fourth relay. The control signal output terminal of the PLC controller is electrically connected to the control signal input terminal of the ultrasonic generator, the input circuit of the first relay, the input circuit of the second relay, the input circuit of the third relay, and the input circuit of the fourth relay via cables. The ultrasonic transducer is electrically connected to the ultrasonic generator via a cable. The signal output terminal of the integrated temperature sensor is connected to the signal input terminal of the PLC controller via a cable.

[0011] The hot water inlet is equipped with a first solenoid valve to control the inflow of hot water, and the output circuit of the first relay is electrically connected to the first solenoid valve via a cable; the cold water inlet is equipped with a second solenoid valve to control the inflow of cold water, and the output circuit of the second relay is electrically connected to the second solenoid valve via a cable; the cold water outlet is equipped with a third solenoid valve to control the outflow of cold water, and the output circuit of the third relay is electrically connected to the third solenoid valve via a cable; the hot water outlet is equipped with a fourth solenoid valve to control the outflow of hot water, and the output circuit of the fourth relay is electrically connected to the fourth solenoid valve via a cable.

[0012] The bottom of the inner pot is fixed with multiple evenly distributed support blocks.

[0013] The grid plate is fixed with downward-extending grid support feet around its perimeter, and the height of the grid support feet is 3 to 6 centimeters.

[0014] The pot lid has a stainless steel ring welded to the top center, and a hanging rod arranged radially along the stainless steel ring is welded into the stainless steel ring; a handle is welded to the side of the pot lid.

[0015] The bottom of the pot lid is provided with a downward-protruding positioning ring, which is inserted into the top opening of the slow cooker.

[0016] The slow cooker has a sealing ring installed at the top. When the lid is placed over the opening at the top of the slow cooker, the sealing ring is sandwiched between the slow cooker and the lid.

[0017] The beneficial effects of this invention are as follows: hot water is introduced into the slow cooker to immerse the packaged food in the hot water for low-temperature slow cooking. After the low-temperature slow cooking is completed, the hot water is drained, and then cold water is introduced into the slow cooker to cool the packaged food. Workers can handle the packaged food in a cooled state, preventing burns and improving the cooling speed of the packaged food. The operation of the ultrasonic generator and ultrasonic transducer causes the water in the slow cooker to vibrate, which promotes the stirring of the water and improves the uniformity of the water temperature in the slow cooker.

[0033] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] like Figures 1 to 13 As shown, a slow cooker device includes: a slow cooker 1, an inner pot 4, a lid 6, and a control cabinet 7. The slow cooker 1 is a rectangular box-shaped structure with an open top, and the inner pot 4 is also a rectangular box-shaped structure with an open top. The lid 6 is rectangular and covers the open top of the slow cooker 1.

[0035] A sealing ring 12 is installed on the top of the slow cooker 1. When the lid 6 is placed on the opening at the top of the slow cooker 1, the sealing ring 12 is sandwiched between the slow cooker 1 and the lid 6.

[0036] The inner pot 4 has several water passage holes 401 on its side wall and bottom, which allow water to flow into or out of the inner pot 4. The bottom of the inner pot 4 is fixed with several evenly distributed support blocks 402, which create a gap between the bottom of the inner pot and the inner bottom of the slow cooker to allow water to flow through. The inner pot 4 has two mirror-symmetrically arranged handle holes 403 on its side plate, which allow workers to insert their fingers into the handle holes 403 to facilitate the handling of the inner pot 4.

[0037] Multiple rectangular grid plates 5 are stacked sequentially from bottom to top in the inner pot 4. Each grid plate 5 has a downward-extending grid support leg 501 fixed around its perimeter. The angle between the grid support leg 501 and the grid plate 5 is 87°, and the height of the grid support leg 501 is 4.5 cm. When the grid plates are stacked, the grid support leg 501 at the bottom of the upper grid plate supports the top of the lower grid plate. The grid support leg 501 supports the grid plate 5, preventing the grid plates from directly stacking on the packaged food and preventing the packaged food at the bottom from being deformed.

[0038] In addition, the height of the grid support foot 501 can be in the range of 3 to 6 cm. The specific height should be selected according to the thickness of the packaged food, as long as the height of the grid support foot 501 is greater than the thickness of the packaged food.

[0039] A stainless steel ring 601 is welded to the center of the top of the pot lid 6. A lifting rod 602 is welded to the stainless steel ring 601 and arranged radially along the stainless steel ring 601. The lifting rod 602 is provided to facilitate the use of the factory's overhead crane or other lifting tools to lift the pot lid 6. A handle 603 is welded to the side of the pot lid 6 to facilitate the manual operation of workers to open or close the pot lid 6.

[0040] The bottom of the lid 6 is provided with a downward protruding positioning ring 604. The positioning ring 604 is inserted into the top opening of the slow cooker 1. The positioning ring 604 is a rectangular frame. The outer contour of the positioning ring 604 is the same as the shape and size of the inner contour of the top opening of the slow cooker. After the positioning ring 604 is inserted into the top opening of the slow cooker, the lid 6 and the slow cooker 1 will not move relative to each other in the horizontal direction.

[0041] The slow cooker 1 has a hot water inlet 101, a cold water inlet 102, and a cold water outlet 103 connected to the inner cavity of the slow cooker 1. A first solenoid valve 8 for controlling the inflow of hot water is installed on the hot water inlet 101, a second solenoid valve 9 for controlling the inflow of cold water is installed on the cold water inlet 102, and a third solenoid valve 10 for controlling the outflow of cold water is installed on the cold water outlet 103. A hot water outlet 104 connected to the inner cavity of the slow cooker 1 is provided at the bottom of the slow cooker 1, and a fourth solenoid valve 11 for controlling the outflow of hot water is installed on the hot water outlet 104.

[0042] During installation, connect the inlet end of the first solenoid valve 8 to the factory's hot water supply network, connect the inlet end of the second solenoid valve 9 to the factory's cold water supply network, connect the outlet end of the third solenoid valve 10 to the factory's hot water return network, and connect the outlet end of the fourth solenoid valve 11 to the factory's cold water return network.

[0043] The control cabinet 7 houses a PLC controller 701, an ultrasonic generator 702, a first relay 703, a second relay 704, a third relay 705, and a fourth relay 706. The control signal output of the PLC controller 701 is electrically connected via cables to the control signal input of the ultrasonic generator 702, the input circuit of the first relay 703, the input circuit of the second relay 704, the input circuit of the third relay 705, and the input circuit of the fourth relay 706. The output circuit of the first relay 703 is electrically connected via a cable to the first solenoid valve 8; the output circuit of the second relay 704 is electrically connected via a cable to the second solenoid valve 9; the output circuit of the third relay 705 is electrically connected via a cable to the third solenoid valve 10; and the output circuit of the fourth relay 706 is electrically connected via a cable to the fourth solenoid valve 11.

[0044] Multiple ultrasonic transducers 3 are installed at the bottom of the slow cooker 1. The ultrasonic transducers 3 are electrically connected to the ultrasonic generator 702 via cables. When the ultrasonic generator 702 and the ultrasonic transducers 3 work, the water in the slow cooker vibrates, which promotes the water to be stirred evenly and improves the uniformity of the water temperature.

[0045] An integrated temperature sensor 2 for monitoring the temperature inside the slow cooker 1 is installed on the rear side. The signal output terminal of the integrated temperature sensor 2 is connected to the signal input terminal of the PLC controller 701 via a cable. The integrated temperature sensor 2 monitors the water temperature in the slow cooker 1 and sends the data to the PLC controller.

[0046] The front of the control cabinet 7 is equipped with a start button switch 707, a pause button switch 708, and an emergency stop button switch 709. The start button switch 707, pause button switch 708, and emergency stop button switch 709 are electrically connected to the signal input terminal of the PLC controller 701 by cables.

[0047] The first solenoid valve 8, the second solenoid valve 9, the third solenoid valve 10, and the fourth solenoid valve 11 are all normally closed flange stainless steel piston solenoid valves.

[0048] Working principle:

[0049] Lay a layer of packaged food flat at the bottom of the inner pot, then place a grid plate on top, and then lay another layer of packaged food flat on the grid plate. Repeat the process of placing the grid plate and laying the packaged food flat until the grid plate and packaged food are placed in the inner pot. Place the inner pot into the slow cooker and close the lid.

[0050] When the worker presses the start button, the PLC controller simultaneously controls the first relay and the ultrasonic generator to start working. The first relay opens the first solenoid valve, allowing hot water to flow into the slow cooker and stop when the designed liquid level is reached. The hot water is used to heat the packaged food in the inner pot. The ultrasonic generator generates a high-frequency AC signal, which causes the ultrasonic transducer to generate ultrasonic waves, thereby causing the water in the slow cooker to vibrate and stir.

[0051] When the water temperature in the slow cooker drops before the heating time is reached, the PLC controller controls the fourth relay and the first relay to start working simultaneously. The fourth relay and the first relay control the fourth solenoid valve and the first solenoid valve to open, allowing hot water to flow in the slow cooker. The hotter hot water replaces the colder hot water in the slow cooker. When the water temperature in the slow cooker returns to the set temperature, the PLC controller controls the fourth relay and the first relay to stop working simultaneously.

[0052] Once the heating time is complete, the PLC controller activates the fourth relay, which in turn opens the fourth solenoid valve to drain the hot water from the slow cooker. Then, the PLC controller activates the second relay, which opens the second solenoid valve to allow cold water to flow into the slow cooker and reach the designed liquid level. After this, the PLC controller activates the second and third relays simultaneously, which in turn open the second and third solenoid valves respectively, allowing cold water to flow through the slow cooker to cool the packaged food.

[0053] After cooling down for a period of time, the PLC controller controls the second relay to stop working and the third relay to continue working. The operation of the third relay causes the third solenoid valve to open and drain the cold water from the slow cooker.
