Description

Technical Field

[0001] This utility model relates to the field of electric rice cooker technology, and more specifically to an electric rice cooker that automatically adds water. Background Technology

[0002] Most rice cookers on the market today have water level lines marked on the inner pot to guide users on how much water to add. However, in actual use, there are several pain points in the user experience:

[0003] 1. Unclear graduation markings: The water level markings on the inner pot of many rice cookers are small and dense, making them easy to misread or overlook, which is especially inconvenient for elderly people with poor eyesight.

[0004] 2. Insufficient differentiation of rice types: Although some rice cookers are labeled with two water level lines, namely "Northeast Rice" and "Silk Rice", there are actually far more types of rice than these two, making it difficult for users to make an accurate judgment; the water requirements for special rice types such as glutinous rice and brown rice are very different, but most rice cookers do not provide corresponding markings.

[0005] 3. Unclear functional distinction: The water level lines for cooking rice and porridge are often displayed side by side without clear distinction, which can easily confuse beginners;

[0006] 4. The water level indicator on multi-functional rice cookers (such as those with a mixed grain rice mode) is insufficient;

[0007] 5. Improper water control: New rice has a high moisture content, and adding water according to the standard water level may result in overly soft rice, while the opposite is true for old rice.

[0008] All of the above factors can lead to rice cooked in a rice cooker having an unpleasant texture. Utility Model Content

In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0032] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] Please refer to an electric rice cooker that automatically adds water. Figure 1-5 As shown, it includes: a pot body 100 and a pot lid 200. The pot body 100 includes: an outer pot 110, an inner pot 120 and a water tank 130.

[0034] The outer pot 110 has an inner cavity, and the inner pot 120 is located in the inner cavity during cooking; the inner pot 120 may be fixed in the inner cavity and cannot be separated, or the inner pot 120 may be inserted into the inner cavity and removed from the inner cavity, making it convenient to clean the inner pot;

[0035] The lid 200 is rotatably mounted on the outer pot 110, and the lid 200 can be rotated to the open position and closed externally.

[0036] The outer pot 110 has a shell 111 and a base 113. The shell 111 is provided with a mounting seat 112 for mounting a water tank 130. The water tank 130 is located outside the outer pot 110. The shell 111 and the mounting seat 112 can be integrally formed to reduce assembly steps.

[0037] Alternatively, the mounting base 112 can also be assembled to the housing 111, such as by means of a snap-fit ​​or screw-locking.

[0038] A water pump 140 is installed inside the outer pot 110. The water inlet of the water pump 140 is connected to the water tank 130, and the water outlet of the water pump 140 is connected to the water outlet 201 of the pot lid 200 through the first pipe 141; the water outlet 201 injects water into the inner pot 120.

[0039] The water pump 140 is installed inside the outer casing 111, near the side of the water tank 130. The water pump 140 is purchased from the market. The pot lid 200 is provided with a water outlet 201, which is fixed at the center of the pot lid 200. The pot lid 200 and the outer pot 110 are rotatably installed. The pot lid 200 can be rotated relative to the outer pot 110 to the open position, and the pot lid 200 can be rotated relative to the outer pot 110 to the closed position. When the pot lid is closed, the water outlet 201 is exactly aligned with the center of the inner pot 120, and water can be added from the center position.

[0040] For example, the pot lid 200 includes an outer lid and an inner lid. The first pipe 141 can be located between the outer lid and the inner lid. The spout 201 is fixed to the center of the outer lid, and the center of the inner lid is provided with a through hole. The tip of the spout 201 passes through the through hole. Generally, the inner lid is detachable relative to the outer lid, which is convenient for cleaning after removing the inner lid. Therefore, after the inner lid is removed, the first pipe 141 is exposed, which is easy to damage or easy to accidentally pull the first pipe 141, resulting in the breakage of the first pipe 141.

[0041] Therefore, as Figure 3 As shown, the outer cover includes an upper shell and a lower shell. The upper shell and the lower shell are assembled by hooks or screws, and are not easily disassembled. They do not need to be disassembled when not in use for maintenance. The first pipe 141 can be placed in the space formed by the upper shell and the lower shell. The water outlet 201 is fixed to the lower shell. The center of the inner cover is provided with a through hole. After the inner cover is installed on the outer cover, the tip of the water outlet 201 passes through the through hole to achieve water output. After the inner cover is removed, the first pipe 141 will not be exposed.

[0042] The outer pot 110 is equipped with a weighing component 300, which uses a weighing module or weighing sensor from the market, such as the weighing module or weighing sensor used in electronic scales currently on the market.

[0043] The weighing component 300 is mainly used to measure the weight of the food placed in the inner pot 120, which mainly refers to rice.

[0044] Furthermore, such as Figure 3 As shown, there are four sets of weighing components 300, which are distributed on the four feet at the bottom of the outer pot 110. When the rice cooker is stably supported on the table, the four sets of weighing components 300 measure the weight. The measurement by the four sets of weighing components 300 is more accurate.

[0045] The rice cooker is equipped with a control system, and the outer pot 110 or the lid 200 is equipped with a control panel, such as... Figure 1 As shown, in this embodiment, a control panel is provided on the pot lid 200, and the desired function can be selected through the control panel.

[0046] The weighing component 300 measures the weight of the rice placed in the inner pot 120 and transmits the measured weight signal to the control system of the rice cooker. The control system issues an instruction based on the calculation to control the water pump 140 to run and inject an appropriate amount of water into the inner pot 120.

[0047] Therefore, there is no need for manual estimation of the specific amount of water to be added. The control system automatically measures and adds water, resulting in rice with a better taste.

[0048] Furthermore, a valve body is provided at the outlet of the water tank 130, and a trigger part is provided in the mounting base 112 to lift the valve stem of the valve body;

[0049] The bottom of the water tank 130 is provided with a water outlet. The valve body is a traditional valve body structure available on the market. When the water tank 130 is placed on the mounting base 112, the trigger part lifts the valve stem of the valve body, and the water outlet is opened. When the water tank 130 is removed from the mounting base 112, the valve stem automatically resets under the action of the spring, and the water outlet is closed.

[0050] like Figure 2 As shown, the mounting base 112 is provided with a water outlet connector 1121, and the water inlet end of the water pump 140 is connected to the water outlet connector 1121 through the second pipe 142.

[0051] In one embodiment, the mounting base 112 is rectangular; the bottom of the water tank 130 is provided with a clearance opening corresponding to the mounting base 112, and the water tank 130 is stably installed on the mounting base 112.

[0052] Furthermore, the clearance opening is opened from the bottom to the top of the water tank 130. After the water tank 130 is assembled on the mounting base 112, the bottom surface of the water tank 130 is supported on a flat surface. For example, if the rice cooker is placed on a table, the bottom surface of the water tank 130 is supported on a flat surface, and the weight of the water tank 130 is borne by the flat surface, so as to avoid the weighing component 300 from affecting the weight of the food in the inner pot 120 due to the different water volume in the water tank 130.

[0053] Alternatively, the water tank 130 can be directly mounted on the mounting base 112, with the weight also borne by the mounting base 112.

[0054] Furthermore, a water tank cover 131 is provided on the top of the water tank 130 to facilitate the replenishment of water into the water tank 130; or, a water inlet is directly provided on the water tank 130.

[0055] Optionally, the water tank 130 can be made transparent so that the water level in the water tank 130 can be effectively observed; or a non-contact water level detector can be installed on the outer pot 110 to detect the water level in the water tank 130 without hindering the relocation of the water tank 130.

[0056] Optionally, a snap-fit ​​structure can be provided between the water tank 130 and the mounting base 112 to prevent the water tank 130 from falling off when moving the rice cooker.

[0057] The following further explains the operating principle of this product:

[0058] It needs to be clarified that, through the setting of the control system program, a table showing the relationship between the weight of the corresponding ingredients and the amount of water added is pre-entered into the control system.

[0059] There are different relationship tables for the number of corresponding ingredient types. For example, the rice cooker is set to have three different types of ingredients to choose from, namely three different types of rice: such as Northeast rice, Silky rice, and Wuchang rice.

[0060] The control system has three pre-entered relationship tables;

[0061] Relationship table A corresponds to Northeast rice, relationship table B corresponds to Silky Rice, and relationship table C corresponds to Wuchang Rice;

[0062] The user selects Northeast rice through the control panel, and the weighing component 300 weighs the rice in the inner pot 120. After receiving the signal, the control system selects the corresponding amount of water to add according to the relationship table A.

[0063] It can adjust the amount of water added for different types of rice, resulting in better-tasting rice.

[0064] First control scheme:

[0065] The water tank is set to be supported on the countertop, and the amount of water in the tank will not affect the weighing component 300 in measuring the weight of the food; rice grains are placed in the inner pot 120, and after the lid 200 is closed, the user selects the corresponding type of rice, such as Northeast rice.

[0066] The weighing component 300 measures the total weight of the inner pot 120 and the rice, and transmits the obtained signal to the control system. The control system subtracts the weight of the inner pot 120 from the weight of the rice to obtain the weight of the rice. The control system finds the relationship between the corresponding weight of rice and the amount of water added through the corresponding lookup table A, and controls the water pump 140 to run and inject water into the inner pot 120.

[0067] It should be noted that the flow rate of water pump 140 is fixed, and the amount of water added can be controlled by controlling the running time of water pump 140.

[0068] The second control scheme:

[0069] The weight of the water tank is supported by the mounting base 112, and the water level in the water tank will affect the weighing of the weighing component 300.

[0070] During measurement, before the inner pot 120 is placed in, the weighing component 300 needs to weigh the food for the first time and set the weighing result to obtain weight A1. After the inner pot 120 is placed in, the weighing component 300 weighs the food for the second time and sets the weighing result to obtain weight A2. The program automatically calculates the difference between weight A2 and weight A1, and subtracts the known weight of the inner pot 120 itself to obtain the weight of the food. The corresponding relationship table A is then looked up to find the relationship between the corresponding weight of rice and the amount of water added, and the water pump 140 is controlled to run to add water to the inner pot 120.

[0071] After adding enough water, water pump 140 stops running, and the rice cooker starts cooking rice.

[0072] Furthermore, in this embodiment, four sets of weighing components 300 are set up. Each of the four sets of weighing components 300 measures one set of data, and the average value of the four sets of data is taken as the final measurement result, making the measurement more accurate.
