Description

Technical Field

[0001] The invention relates to the technical field of electric rice cookers, in particular to a fast cooling electric rice cooker and an electric rice cooker control system. Background Art

[0002] In the prior art, electric rice cookers are daily kitchen appliances that are widely used to cook rice, porridge and other foods. However, after the rice cooker finishes cooking, the temperature of the rice or porridge is usually very high, and it takes a while to cool down to a temperature suitable for consumption. This waiting not only reduces the user's dining experience, but may also affect the taste and nutrition of the food due to long-term high temperature. In order to solve this problem, some methods have appeared on the market that attempt to reduce the temperature through natural cooling or manual cooling, but these methods often have poor effects and require manual operation by the user, which increases the cumbersomeness of use. In addition, although some high-end rice cookers are equipped with a keep warm function, the insulation temperature is usually high and cannot meet the user's needs for immediate consumption.

[0003] Prior art CN218683701 U discloses a fast-cooling electric rice cooker, which is used to overcome the defect of slow cooling speed of existing electric rice cookers. The electric rice cooker includes a pot body, an inner pot placed in the pot body, and a pot cover arranged on the pot body. The pot body is provided with a heating plate; the inner pot is an uncoated inner pot, the heating plate heats the uncoated inner pot, and the inner wall of the uncoated inner pot is a metal layer directly in contact with food; the lower surface of the heating plate has a mounting platform, and a semiconductor cooling plate is provided on the mounting platform, and the semiconductor cooling plate is attached to the mounting platform. The semiconductor cooling plate works to accelerate the cooling of the heating plate, thereby reducing the further heat transfer from the heating plate to the inner pot, and realizes the cooling of the bottom of the inner pot, so as to avoid the continuous high temperature at the bottom of the inner pot during the cooking process, resulting in excessive water loss of the rice at the bottom of the inner pot, and to avoid the rice at the bottom of the inner pot sticking to the pot. However, the cooling effect of the semiconductor cooling plate is effective, and the cooling range is small, which easily causes uneven temperature in various parts of the electric rice cooker, affecting the cooking quality of the food.

[0004] Therefore, it is necessary to improve the existing electric cooker to overcome the defect of the prior art. Summary of the invention

[0005] In order to overcome the problems existing in the related art, one of the purposes of the present invention is to provide a fast cooling rice cooker, which can evenly and quickly cool the inner pot through the cooling cavity, thereby reducing the waiting time of the user while ensuring the quality of the food and improving the user experience.

[0006] A fast cooling electric rice cooker comprises a cooker body, wherein an inner pot is arranged in the cooker body, and a cooling cavity is also arranged in the cooker body, wherein the cooling cavity is arranged at the periphery of the inner pot and connected with the inner pot; wherein a liquid storage box is also arranged in the cooker body, wherein the liquid storage box is connected with the cooling cavity through a connecting pipe, and a water pump is arranged on the connecting pipe.

[0007] The cooling chamber is arranged on the periphery of the inner pot and is closely connected to the inner pot. This design enables the liquid stored in the cooling chamber to quickly cool the inner pot after cooking is completed, thereby shortening the waiting time of the user. The liquid storage box is used to store the liquid required for cooling. The liquid storage box is connected to the cooling chamber through a connecting pipe, and a water pump is installed on the connecting pipe. When cooling is required, the water pump starts and pumps the cooling liquid in the liquid storage box into the cooling chamber through the connecting pipe. The cooling liquid circulates in the cooling chamber and takes away the heat of the inner pot through heat exchange, thereby achieving a rapid cooling effect. By timely cooling the inner pot, the food is effectively prevented from being overheated, thereby maintaining the original flavor and nutritional content of the food.

[0008] In a preferred technical solution of the present invention, the cooling cavity partially or completely covers the outer wall of the inner container.

[0009] The design of the cooling chamber partially or completely covering the outer wall of the inner pot ensures that the cooling liquid can fully and evenly contact the outer wall of the inner pot, thereby achieving efficient heat exchange. This design allows the temperature of the food in the inner pot to drop quickly, greatly shortening the user's waiting time.

[0010] In a preferred technical solution of the present invention, a heat exchanger is further provided on the connecting pipe, and the heat exchanger includes a heat dissipation cavity and heat dissipation fins. The heat dissipation cavity is connected to the connecting pipe, and the heat dissipation fins are provided on the heat dissipation cavity.

[0011] In a preferred technical solution of the present invention, a semiconductor refrigeration sheet is provided on the outer wall of the heat dissipation cavity, and a cooling end of the semiconductor refrigeration sheet is connected to the heat dissipation cavity.

[0012] One end of the connecting pipe is connected to the liquid storage box, and the other end is connected to the heat dissipation cavity. A heat exchanger is installed on the connecting pipe. The heat exchanger consists of a heat dissipation cavity and heat dissipation fins. The heat dissipation cavity is closely connected to the connecting pipe to ensure that the cooling liquid can flow smoothly. The heat dissipation fins are arranged on the outer wall of the heat dissipation cavity, which increases the heat exchange area and improves the cooling efficiency.

[0013] Preferably, a semiconductor cooling sheet is arranged on the outer wall of the heat dissipation cavity. The semiconductor cooling sheet is a highly efficient cooling element, and its cooling end is closely connected with the heat dissipation cavity. When the semiconductor cooling sheet is working, the cooling end will quickly reduce the temperature, thereby taking away the heat in the heat dissipation cavity through heat conduction, and realizing rapid cooling.

[0014] When the rice cooker finishes cooking, the water pump automatically starts to pump the cooling liquid in the liquid storage box into the heat dissipation cavity in the heat exchanger through the connecting pipe. The cooling liquid circulates in the heat dissipation cavity and dissipates the heat to the external environment through the heat dissipation fins. At the same time, the semiconductor refrigeration chip starts working, and its cooling end can quickly reduce the temperature of the heat dissipation cavity, further accelerating the cooling process. In this way, the temperature of the food in the inner pot can be quickly reduced, achieving a rapid cooling effect.

[0015] Through the synergistic effect of the heat exchanger and the semiconductor cooling sheet in this embodiment, the rice cooker in this embodiment realizes an efficient and rapid cooling function. The cooling liquid circulates in the heat dissipation cavity and increases the heat exchange area through the heat dissipation fins, thereby improving the cooling efficiency. At the same time, the cooling end of the semiconductor cooling sheet directly reduces the temperature of the heat dissipation cavity, further accelerating the cooling process. This design allows users to enjoy cooled food in a short time, thereby improving cooking efficiency.

[0016] In a preferred technical solution of the present invention, a temperature sensor is further provided in the pot body, and the temperature sensor is connected to the inner pot.

[0017] The temperature sensor is closely connected to the inner pot and can monitor the temperature changes of the inner pot in real time and accurately. With the precise feedback of the temperature sensor, the rice cooker can more accurately control the cooking and cooling process to ensure the best quality and taste of the food.

[0018] When the rice cooker starts cooking, the temperature sensor monitors the temperature of the inner pot in real time and adjusts it precisely according to the preset cooking program. After cooking is completed, the water pump starts automatically and pumps the cooling liquid in the liquid storage box into the heat dissipation cavity in the heat exchanger through the connecting pipe. The cooling liquid circulates in the heat dissipation cavity and dissipates heat to the external environment through the heat dissipation fins. At the same time, the semiconductor refrigeration chip starts working, and its cooling end quickly lowers the temperature of the heat dissipation cavity, further accelerating the cooling process. The temperature sensor continuously monitors the temperature changes of the inner pot to ensure that the cooling process is both fast and accurate.

[0019] In a preferred technical solution of the present invention, a heat-conducting layer is provided between the side wall of the cooling cavity and the inner liner.

[0020] In actual use, the heat-conducting layer is made of high thermal conductivity material, which can quickly transfer the heat of the inner pot to the cooling cavity, thereby further improving the cooling efficiency. The addition of the heat-conducting layer enables the rice cooker to reduce the temperature of the inner pot more evenly and quickly during the cooling process.

[0021] In a preferred technical solution of the present invention, a plurality of liquid level sensors are arranged in the liquid storage box, and the plurality of liquid level sensors are arranged in the liquid storage box along the height direction of the liquid storage box.

[0022] The liquid level sensor will monitor the liquid level in the liquid storage box in real time to ensure that the cooling liquid is sufficient. When the cooling liquid in the liquid storage box is insufficient, an alarm will be issued to remind the user to add coolant (water) to the liquid storage box in time.

[0023] In a preferred technical solution of the present invention, a transparent window is provided on the side wall of the pot body, and a liquid level display bar is provided in the liquid storage box, and the liquid level display bar corresponds to the transparent window.

[0024] In a preferred technical solution of the present invention, a mounting position is provided in the pot body, a card slot is provided on a side wall of the mounting position, a card block is provided on a side wall of the liquid storage box, and the card block and the card slot are card-engaged with each other.

[0025] In this embodiment, the liquid level of the liquid storage box is displayed through a transparent window and a liquid level display bar. Compared with the implementation method of using a liquid level sensor for detection, this embodiment has a simpler structure and reduces the use of electronic equipment, which can reduce the probability of malfunction.

[0026] A second object of the present invention is to provide an electric cooker control system, which is applied in a fast cooling electric cooker as described above.

[0027] The control process of the control system is as follows: When the rice cooker starts cooking, the temperature sensor will monitor the temperature of the inner pot in real time and accurately adjust it according to the preset cooking program. At the same time, the liquid level sensor will monitor the liquid level in the liquid storage box in real time to ensure that there is enough cooling liquid. After cooking is completed, the water pump starts automatically and pumps the cooling liquid in the liquid storage box into the heat dissipation cavity in the heat exchanger through the connecting pipe. The cooling liquid circulates in the heat dissipation cavity and dissipates heat to the external environment through the heat dissipation fins. At the same time, the semiconductor refrigeration chip starts working, and its cooling end quickly lowers the temperature of the heat dissipation cavity. The heat conductive layer gives full play to its excellent thermal conductivity and quickly transfers the heat of the inner pot to the cooling cavity. Under the monitoring of the temperature sensor, the rice cooker can intelligently control the cooling process to ensure that the quality and taste of the food are in the best state and avoid waste or insufficient cooling liquid.

[0028] The beneficial effects of the present invention are:

[0029] The invention provides a fast cooling electric rice cooker, which comprises a cooker body, an inner pot is arranged in the cooker body, and a cooling cavity is also arranged in the cooker body, and the cooling cavity is arranged on the periphery of the inner pot and connected with the inner pot. A liquid storage box is also arranged in the cooker body, and the liquid storage box is connected with the cooling cavity through a connecting pipe, and a water pump is arranged on the connecting pipe. During the use of the electric rice cooker, the liquid storage box is used to store liquid required for cooling. The liquid storage box is connected with the cooling cavity through a connecting pipe, and a water pump is installed on the connecting pipe. When cooling is required, the water pump is started to pump the cooling liquid in the liquid storage box into the cooling cavity through the connecting pipe. The cooling liquid circulates in the cooling cavity, and takes away the heat of the inner pot through heat exchange, thereby achieving a fast cooling effect. Moreover, the cooling cavity is coated on the periphery of the outer periphery, which can realize uniform cooling of the inner pot, effectively avoiding excessive heating of food, thereby maintaining the original flavor and nutritional components of the food.

[0039] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0040] The prior art discloses a rice cooker with rapid cooling, which includes a pot body, an inner pot placed in the pot body, and a pot cover arranged on the pot body, wherein a heating plate is arranged in the pot body; the inner pot is an uncoated inner pot, the heating plate heats the uncoated inner pot, and the inner wall of the uncoated inner pot is a metal layer directly in contact with food; the lower surface of the heating plate has a mounting platform, and a semiconductor cooling sheet is arranged on the mounting platform, and the semiconductor cooling sheet is attached to the mounting platform. The semiconductor cooling sheet works to accelerate the cooling of the heating plate, thereby reducing the further heat transfer from the heating plate to the inner pot, and realizes the cooling of the bottom of the inner pot, so as to avoid the continuous high temperature at the bottom of the inner pot during the cooking process, resulting in excessive water loss of the rice at the bottom of the inner pot, and to avoid the rice at the bottom of the inner pot sticking to the pot. However, the cooling effect of the semiconductor cooling sheet is effective, and the cooling range is small, which easily causes uneven temperature in various parts of the rice cooker, affecting the cooking quality of the food.

[0041] Based on this, the present application provides a fast cooling rice cooker.

[0042] Example 1

[0043] like Figure 1-Figure 6 As shown, a fast cooling rice cooker provided in this embodiment includes a cooker body 1, in which an inner pot 7 is arranged, and a cooling chamber 6 is also arranged in the cooker body 1, and the cooling chamber 6 is arranged on the periphery of the inner pot 7 and connected to the inner pot 7; the cooker body 1 is also provided with a liquid storage box 5, and the liquid storage box 5 is connected with the cooling chamber 6 through a connecting pipe 2, and a water pump 3 is arranged on the connecting pipe 2.

[0044] The cooling chamber 6 is arranged on the periphery of the inner pot 7 and is closely connected with the inner pot 7. This design enables the liquid stored in the cooling chamber 6 to quickly cool the inner pot 7 after cooking is completed, thereby shortening the waiting time of the user. The liquid storage box 5 is used to store the liquid required for cooling. The liquid storage box 5 is connected to the cooling chamber 6 through the connecting pipe 2, and the connecting pipe 2 is equipped with a water pump 3. When cooling is required, the water pump 3 is started to pump the cooling liquid in the liquid storage box 5 into the cooling chamber 6 through the connecting pipe 2. The cooling liquid circulates in the cooling chamber 6, and takes away the heat of the inner pot 7 through heat exchange, thereby achieving a rapid cooling effect. By timely cooling the inner pot 7, excessive heating of the food is effectively avoided, thereby maintaining the original flavor and nutritional components of the food.

[0045] In this embodiment, a temperature sensor 11 is further provided in the pot body 1 , and the temperature sensor 11 is connected to the inner pot 7 .

[0046] The temperature sensor 11 is closely connected to the inner pot 7, and can monitor the temperature change of the inner pot 7 in real time and accurately. Through the precise feedback of the temperature sensor 11, the rice cooker can more accurately control the cooking and cooling process to ensure that the quality and taste of the food are in the best state.

[0047] When the rice cooker starts cooking, the temperature sensor 11 will monitor the temperature of the inner pot 7 in real time and accurately adjust it according to the preset cooking program. After cooking is completed, the water pump 3 starts automatically and pumps the cooling liquid in the liquid storage box 5 into the heat dissipation cavity 41 in the heat exchanger 4 through the connecting pipe 2. The cooling liquid circulates in the heat dissipation cavity 41 and dissipates heat to the external environment through the heat dissipation fins 42. At the same time, the semiconductor refrigeration sheet 8 starts working, and its cooling end quickly lowers the temperature of the heat dissipation cavity 41, further accelerating the cooling process. The temperature sensor 11 continuously monitors the temperature changes of the inner pot 7 to ensure that the cooling process is both fast and accurate.

[0048] In a more preferred implementation manner of this embodiment, a heat conducting layer is provided between the side wall of the cooling cavity 6 and the inner liner 7 .

[0049] In actual use, the heat-conducting layer is made of a material with high thermal conductivity, which can quickly transfer the heat of the inner pot 7 to the cooling chamber 6, thereby further improving the cooling efficiency. The addition of the heat-conducting layer enables the rice cooker to more evenly and quickly reduce the temperature of the inner pot 7 during the cooling process.

[0050] Specifically, the material of the heat-conducting layer of the present application can be a metal material including aluminum alloy, iron alloy or stainless steel. Among them, aluminum alloy has the advantages of lightness, good thermal conductivity and low cost, and can quickly transfer heat to the cooling chamber 6. Iron alloy is known for its good thermal conductivity and durability, can withstand high temperature and high pressure, and is not easy to deform or damage. Stainless steel is famous for its corrosion resistance and high temperature resistance, and can effectively resist the erosion of moisture and oxygen, thereby extending the service life of the rice cooker.

[0051] In actual use, when the electric cooker is cooking, the cooling chamber 6 does not have cooling liquid. After cooking is finished, cooling liquid (water) is sent into the cooling chamber 6 by the water pump 3.

[0052] Example 2

[0053] This embodiment is improved on the basis of Embodiment 2.

[0054] like Figure 1-Figure 6 As shown, in this embodiment, the cooling chamber 6 partially covers the outer wall of the inner tank 7.

[0055] The design of the cooling chamber 6 partially or completely covering the outer wall of the inner pot 7 ensures that the cooling liquid can fully and evenly contact the outer wall of the inner pot 7, thereby achieving efficient heat exchange. This design allows the temperature of the food in the inner pot 7 to be quickly reduced, greatly shortening the waiting time of the user.

[0056] In this embodiment, the cooling chamber 6 covers the bottom and part of the side wall of the inner pot 7. The cooling chamber 6 covers part of the outer wall of the inner pot 7, thereby realizing fast and uniform heat exchange. In actual use, the upper part of the inner pot 7 is usually free of food. In this embodiment, the cooling chamber 6 does not cover the upper part of the inner pot 7, thereby saving materials and reducing manufacturing costs.

[0057] Example 3

[0058] This embodiment is improved on the basis of Embodiment 2.

[0059] like Figure 1-Figure 6 As shown, in this embodiment, the cooling chamber 6 completely covers the outer wall of the inner tank 7.

[0060] The design of the cooling chamber 6 partially or completely covering the outer wall of the inner pot 7 ensures that the cooling liquid can fully and evenly contact the outer wall of the inner pot 7, thereby achieving efficient heat exchange. This design allows the temperature of the food in the inner pot 7 to be quickly reduced, greatly shortening the waiting time of the user.

[0061] In this embodiment, the cooling chamber 6 completely covers the bottom and side walls of the inner liner 7. Different from the embodiment 2, the cooling chamber 6 completely covers the side walls of the inner liner 7. It can be understood that the top of the inner liner 7 is flush with the top of the cooling chamber 6.

[0062] Due to the complete covering design of the outer wall of the inner pot 7 by the cooling chamber 6, the cooling liquid can fully and evenly contact the entire outer wall of the inner pot 7, achieving a more efficient and uniform heat exchange. This design allows the temperature of the food in the inner pot 7 to be quickly and comprehensively reduced, further shortening the user's waiting time and improving the uniformity of cooling. Compared with Example 2, the cost of the rice cooker of this application is higher.

[0063] Example 4

[0064] This embodiment is improved on the basis of embodiment 1.

[0065] like Figure 1-Figure 6 As shown, in this embodiment, a heat exchanger 4 is further provided on the connecting pipe 2 , and the heat exchanger 4 includes a heat dissipation cavity 41 and heat dissipation fins 42 . The heat dissipation cavity 41 is connected to the connecting pipe 2 , and the heat dissipation fins 42 are provided on the heat dissipation cavity 41 .

[0066] In this embodiment, a semiconductor refrigeration sheet 8 is disposed on the outer wall of the heat dissipation cavity 41 , and a cooling end of the semiconductor refrigeration sheet 8 is connected to the heat dissipation cavity 41 .

[0067] One end of the connecting pipe 2 is connected to the liquid storage box 5, and the other end is connected to the cooling chamber 6. A heat exchanger 4 is installed on the connecting pipe 2. The heat exchanger 4 consists of a heat dissipation chamber 41 and heat dissipation fins 42. The heat dissipation chamber 41 is closely connected to the connecting pipe 2 to ensure that the cooling liquid can flow smoothly. The heat dissipation fins 42 are arranged on the outer wall of the heat dissipation chamber 41, which increases the heat exchange area and improves the cooling efficiency.

[0068] Preferably, a semiconductor cooling sheet 8 is provided on the outer wall of the heat dissipation cavity 41. The semiconductor cooling sheet 8 is a highly efficient cooling element, and its cooling end is closely connected with the heat dissipation cavity 41. When the semiconductor cooling sheet 8 is working, the cooling end will quickly reduce the temperature, thereby taking away the heat in the heat dissipation cavity 41 through heat conduction, thereby achieving rapid cooling.

[0069] When the rice cooker completes the cooking task, the water pump 3 automatically starts to pump the cooling liquid in the liquid storage box 5 into the heat dissipation cavity 41 in the heat exchanger 4 through the connecting pipe 2. The cooling liquid circulates in the heat dissipation cavity 41 and dissipates heat to the external environment through the heat dissipation fins 42. At the same time, the semiconductor refrigeration sheet 8 starts to work, and its cooling end can quickly reduce the temperature of the heat dissipation cavity 41, further accelerating the cooling process. In this way, the temperature of the food in the inner pot 7 can be quickly reduced, achieving a rapid cooling effect.

[0070] Through the synergistic effect of the heat exchanger 4 and the semiconductor cooling sheet 8 in this embodiment, the electric rice cooker in this embodiment realizes an efficient and rapid cooling function. The cooling liquid circulates in the heat dissipation cavity 41 and increases the heat exchange area through the heat dissipation fins 42, thereby improving the cooling efficiency. At the same time, the cooling end of the semiconductor cooling sheet 8 directly reduces the temperature of the heat dissipation cavity 41, further accelerating the cooling process. This design allows users to enjoy cooled food in a short time, thereby improving cooking efficiency.

[0071] In practical applications, the cross section of the heat dissipation cavity 41 may be circular or rectangular.

[0072] Example 5

[0073] This embodiment is improved on the basis of Embodiment 2.

[0074] like Figure 1-Figure 6 As shown, in this embodiment, a plurality of liquid level sensors 51 are disposed in the liquid storage box 5 , and the plurality of liquid level sensors 51 are disposed in the liquid storage box 5 along the height direction of the liquid storage box 5 .

[0075] The liquid level sensor 51 can monitor the liquid level in the liquid storage box 5 in real time to ensure the abundance of cooling liquid. When the cooling liquid in the liquid storage box 5 is insufficient, an alarm is sounded to remind the user to add cooling liquid (water) in the liquid storage box 5 in time.

[0076] More specifically, two liquid level sensors 51 can be provided, one of which is provided at the top of the inner wall of the liquid storage box 5, and the other is provided at the middle of the inner wall of the liquid storage box 5. It can be understood that the two liquid level sensors 51 are respectively a top sensor and a middle sensor. When the top sensor detects that there is no coolant (water) at the location, a reminder is issued. At this time, the user may not add coolant to the liquid storage box 5, because there is still a certain amount of coolant in the liquid storage box 5. When the middle sensor detects that there is no coolant (water) at the location, a second reminder is issued, and the second reminder is more prominent than the first reminder, so as to remind the user to add water to the liquid storage box 5 in time.

[0077] The liquid level sensor 51 of the present application can be a photoelectric liquid level sensor 51, and the specific model can be any one of FS-IR1902D, FS-I R02B, and FS-I R82B. It can also be an ultrasonic liquid level sensor 51, such as DL14-01 and LU12-5001 of FLOWL I NE in the United States. It can also be a float switch, which is a contact sensor that measures the liquid level by the rise and fall of the float. The float switch does not require power supply, directly indicates, has relatively low cost, and provides multiple output options.

[0078] Example 6

[0079] This embodiment is improved on the basis of embodiment 1.

[0080] like Figure 1-Figure 6 As shown, in this embodiment, a transparent window is provided on the side wall of the pot body 1, and a liquid level display bar 52 is provided in the liquid storage box 5, and the liquid level display bar 52 corresponds to the transparent window.

[0081] More preferably, in this embodiment, a mounting position is provided in the pot body 1, a slot is provided on a side wall of the mounting position, a clamping block 53 is provided on a side wall of the liquid storage box 5, and the clamping block 53 is clamped with the slot.

[0082] Different from Example 5, in this embodiment, the liquid level of the liquid storage box 5 is displayed through a transparent window and a liquid level display bar 52. Compared with the implementation method using a liquid level sensor 51 for detection, the structure of this embodiment is simpler and the use of electronic equipment is reduced, which can reduce the probability of malfunction.

[0083] In actual application, the structure of the liquid level display bar 52 includes a display bar body and scale marks. The display bar body is made of transparent or translucent plastic material, in a long strip shape, and adapted to the height of the liquid storage box 5. Clear scale lines are engraved on the display bar body to indicate different liquid level heights, and the scale lines are distinguished by different colors so that users can read the liquid level value more intuitively.

[0084] Moreover, the clamping block 53 and the clamping slot are mutually clamped, so that the liquid storage box 5 is stably installed in the pot body 1. This installation method is not only simple and fast, but also ensures the accurate correspondence between the liquid level display bar 52 and the transparent window.

[0085] In practical applications, the clamping block 53 may be a wedge-shaped clamping block 53 , and the clamping slot and the clamping block 53 are adapted to each other.

[0086] Example 7

[0087] like Figure 1-Figure 6 As shown, this embodiment provides an electric rice cooker control system, which is applied to a fast cooling electric rice cooker as described above.

[0088] Specifically, the control system includes a central control unit, a user interface, a sensor network, an actuator control and a communication module. The central control unit is the core of the control system. The central control unit is responsible for receiving and processing data from various sensors, including temperature sensors 11, liquid level sensors 51, etc., and making decisions according to preset cooking programs and algorithms to control the working status of various actuators (such as heating elements, water pumps 3, semiconductor cooling sheets 8, etc. of electric rice cookers). The user interface is a window for users to interact with the control system, including a display screen and a button / touch panel. Users can set cooking modes, select cooling speeds, view current status and information, etc. through the user interface to achieve a personalized cooking experience. The user interface can be a display screen set on the cooker body 1. The sensor network is composed of multiple sensors, including but not limited to temperature sensors 11, liquid level sensors 51, etc., which are distributed in various key parts of the electric rice cooker, and monitor various parameters in the cooking and cooling processes in real time, such as the temperature of the inner pot 7, the liquid level of the liquid storage box 5, etc., and transmit the data to the central control unit. The actuator includes a heating element (for heating during cooking), a water pump 3 (for pumping cooling liquid into the cooling chamber 6), a semiconductor cooling sheet 8 (for accelerating the cooling process), etc. The control system realizes automation and precise control of the cooking and cooling processes by precisely controlling the working status and time of these actuators. The communication module enables users to remotely control the rice cooker through mobile devices such as smartphones and tablets, or upload cooking data to the cloud for storage and analysis.

[0089] The control process of the control system is as follows: when the rice cooker starts cooking, the temperature sensor 11 will monitor the temperature of the inner pot 7 in real time and accurately control it according to the preset cooking program. At the same time, the liquid level sensor 51 will monitor the liquid level in the liquid storage box 5 in real time to ensure that the cooling liquid is sufficient. After cooking is completed, the water pump 3 automatically starts to pump the cooling liquid in the liquid storage box 5 into the heat dissipation cavity 41 in the heat exchanger 4 through the connecting pipe 2. The cooling liquid circulates in the heat dissipation cavity 41 and dissipates heat to the external environment through the heat dissipation fins 42. At the same time, the semiconductor refrigeration sheet 8 starts working, and its cooling end quickly reduces the temperature of the heat dissipation cavity 41. The heat conductive layer gives full play to its excellent thermal conductivity and quickly transfers the heat of the inner pot 7 to the heat dissipation cavity 41. Under the monitoring of the temperature sensor 11, the rice cooker can intelligently control the cooling process to ensure that the quality and taste of the food are in the best state and avoid waste or insufficiency of cooling liquid.

[0090] During the cooling process, the temperature of the coolant in the cooling chamber 6 can be obtained. After cold water is introduced into the cooling chamber 6 for a set time, the cold water is discharged to the liquid storage box 5, and then the cold water in the liquid storage box 5 is introduced into the cooling chamber 6 to cool the inner tank 7. This cycle is repeated to achieve cooling of the inner tank 7.

[0091] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values ​​of the parts and steps set forth in these embodiments do not limit the scope of the present application. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to those of ordinary skill in the relevant field may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be considered as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so that once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings. In the description of the present application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present application; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0092] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0093] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this application. The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
