Description

Technical Field

[0001] The invention relates to the technical field of household appliances, and in particular to a water adding control method and a control device for an electric rice cooker and an electric rice cooker. Background Art

[0002] With the continuous improvement of living standards, people have higher and higher requirements for the intelligence of home appliances. The rice cooker is a commonly used household appliance. At present, the rice cooker can automatically and quantitatively inject the water in the water tank into the cooking cavity according to the amount of rice in the cooking cavity. In the prior art, when the water in the water tank is lower than the maximum water level, a water-adding alarm will be issued to prevent cooking failure due to lack of water. Therefore, in actual use, water needs to be added to the water tank to the maximum water level before cooking each time. However, when the amount of rice in the cooking cavity is relatively small, even if the water in the water tank is lower than the maximum water level, it may meet the current water demand. At this time, the water-adding operation will increase the user's unnecessary workload and affect the user's experience. Summary of the invention

[0003] The invention provides a water adding control method for an electric rice cooker, a control device and an electric rice cooker, which are used to solve or improve the problem that the water adding method of the existing electric rice cooker causes unnecessary water adding operations for users and affects the user experience.

[0004] According to a first aspect of the present invention, there is provided a method for controlling water addition in an electric rice cooker, comprising the following steps:

[0005] S1: based on the actual weight of the rice being less than or equal to the intermediate preset weight of the rice cooker, determining that the actual required amount of water is within the intermediate preset amount of water;

[0006] S2: Based on the fact that the actual water volume in the water tank is greater than or equal to the intermediate preset water volume, injecting an actually required amount of water into the cooking cavity.

[0007] Among them, 0<the intermediate preset weight<the maximum rice cooking amount of the rice cooker.

[0008] According to a method for controlling water addition to an electric rice cooker provided by the present invention, the step S2 further comprises: sending a water addition signal based on a state that the actual water volume in the water tank is less than the intermediate preset water volume.

[0009] According to a method for controlling water addition to a rice cooker provided by the present invention, before step S1, the method further comprises:

[0010] S01: Based on the fact that the actual water volume in the water tank is greater than or equal to the maximum preset water volume, injecting an actually required amount of water into the cooking cavity;

[0011] Based on the fact that the actual water volume in the water tank is less than the maximum preset water volume, the step S1 is initiated.

[0012] According to a method for controlling water addition to a rice cooker provided by the present invention, the step S1 comprises:

[0013] When the actual weight of the rice is less than or equal to the middle preset weight of the rice cooker, it is determined that the actually required water level is not higher than the middle preset water level.

[0014] According to a method for controlling water addition to a rice cooker provided by the present invention, the step S2 comprises:

[0015] The float in the float level gauge in the water tank does not trigger the intermediate preset water level signal, and it is determined that the actual water volume in the water tank is less than the intermediate preset water volume.

[0016] According to a method for controlling water addition to an electric rice cooker provided by the present invention, the step of injecting an actually required amount of water into the cooking cavity based on the actual amount of water in the water tank being greater than or equal to a maximum preset amount of water comprises:

[0017] The actual water level in the water tank is not lower than the highest preset water level, and it is determined that the actual water volume in the water tank is greater than or equal to the maximum preset water volume.

[0018] According to a method for controlling water addition to a rice cooker provided by the present invention, the actual water level in the water tank is not lower than the highest preset water level, which specifically includes:

[0019] The float in the float level gauge in the water tank triggers the intermediate preset water level signal and the maximum preset water level signal at the same time to ensure that the actual water level in the water tank is not lower than the maximum preset water level.

[0020] According to a method for controlling water addition to a rice cooker provided by the present invention, before step S01, the method further comprises:

[0021] Based on the detection result that the water tank is not installed in place, an alarm signal is issued;

[0022] Based on the detection result that the water tank is installed in place, the step S01 is started.

[0023] According to a second aspect of the present invention, there is provided a water adding control device for an electric rice cooker, comprising:

[0024] Weighing module, used to detect the actual weight of rice;

[0025] A water volume monitoring module is used to monitor the actual water volume in the water tank;

[0026] The control module is used to determine that the actual required water volume is within the intermediate preset water volume based on the actual weight of the rice being less than or equal to the intermediate preset water volume, and to inject the actually required water volume into the cooking cavity based on the actual water volume in the water tank being greater than or equal to the intermediate preset water volume.

[0027] According to a third aspect of the present invention, there is provided an electric rice cooker, which operates with the electric rice cooker water addition control method as described above or comprises the electric rice cooker water addition control device as described above.

[0028] In the rice cooker water adding control method provided by the present invention, first, based on the actual weight of rice being less than or equal to the intermediate preset weight of the rice cooker, it is determined that the actual required water volume is within the intermediate preset water volume. Subsequently, based on the state that the actual water volume in the water tank is greater than or equal to the intermediate preset water volume, the actual required water volume is injected into the cooking cavity.

[0029] Specifically, the rice cooker is set with an intermediate preset weight, 0<intermediate preset weight<the maximum rice cooking amount of the rice cooker. The intermediate preset weight can be set to the amount of rice that the user usually cooks. For example, the intermediate preset weight can be half of the maximum rice cooking amount of the rice cooker. In addition, the rice cooker is also set with a rice-to-water ratio. For example, the rice-to-water ratio can select any value within 1.1-1.5 according to different rice cooking modes. The intermediate preset water volume can be determined based on the intermediate preset weight and the rice-to-water ratio. In other words, the intermediate preset water volume corresponds to the intermediate preset weight and the rice-to-water ratio, that is, the intermediate preset water volume is the amount of water required for cooking rice when the amount of rice is equal to the intermediate preset weight and the rice-to-water ratio is set.

[0030] In actual use, the rice in the cooking cavity is first weighed. After the weighing is completed, the actual amount of rice in the cooking cavity is compared with the intermediate preset weight of the rice cooker. When the actual weight of the rice in the cooking cavity is less than or equal to the intermediate preset weight of the rice cooker, it is determined that the actual required amount of water is within the intermediate preset amount of water. Subsequently, the actual amount of water in the water tank is compared with the intermediate preset amount of water. When the actual amount of water in the water tank is greater than or equal to the intermediate preset amount of water, it is confirmed that the current amount of water in the water tank can meet the needs of this rice cooking, and the water of the actual required amount of water is controlled to be injected into the cooking cavity. For example, a water injection pipe is provided between the cooking cavity and the water tank, and a water pump and a flow meter are provided on the water injection pipe. When the actual amount of water in the water tank is greater than or equal to the intermediate preset amount of water, the water pump is controlled to be turned on so that the water in the water tank is injected into the cooking cavity. When the flow meter detects that the amount of water injected into the cooking cavity reaches the actual required amount of water, the water pump is turned off and the injection of water into the cooking cavity is stopped.

[0031] By setting in this way, the electric rice cooker is set with an intermediate preset weight, and the corresponding rice-to-water ratio is set in different modes, and the intermediate preset water volume is set corresponding to the intermediate preset weight and the rice-to-water ratio. In actual use, when the actual weight of the rice in the cooking cavity is less than or equal to the intermediate preset weight of the electric rice cooker, and the actual amount of water in the water tank is greater than or equal to the intermediate preset water volume, there is no need to add water, and the water in the water tank can be injected into the cooking cavity to cook rice. As a result, the number of unnecessary water-adding operations by the user is reduced, greatly improving the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0045] Combine the following Figures 1 to 5 A method for controlling water addition in a rice cooker, a control device and a rice cooker provided by the present invention are described. It should be understood that the following description is only an illustrative embodiment of the present invention and does not constitute any particular limitation to the present invention.

[0046] The embodiment of the first aspect of the present invention provides a method for controlling water addition in an electric rice cooker, such as Figure 1 As shown, including:

[0047] S1: based on the actual weight of the rice being less than or equal to the intermediate preset weight of the rice cooker, determining that the actual required amount of water is within the intermediate preset amount of water;

[0048] S2: based on the state that the actual water volume in the water tank 300 is greater than or equal to the intermediate preset water volume, injecting the actually required water volume into the cooking cavity;

[0049] Among them, 0<the intermediate preset weight<the maximum rice cooking amount of the rice cooker.

[0050] In the rice cooker water adding control method provided by the present invention, first, based on the actual weight of rice being less than or equal to the intermediate preset weight of the rice cooker, it is determined that the actual required water volume is within the intermediate preset water volume. Subsequently, based on the state that the actual water volume in the water tank 300 is greater than or equal to the intermediate preset water volume, the actual required water volume is injected into the cooking cavity.

[0051] Specifically, the rice cooker is set with an intermediate preset weight, 0<intermediate preset weight<the maximum amount of rice that the rice cooker can cook. The intermediate preset weight can be set to the amount of rice that the user usually cooks. The maximum amount of rice that the rice cooker can cook is the maximum amount of rice that can be placed in the cooking chamber. For example, the intermediate preset weight can be half of the maximum amount of rice that the rice cooker can cook. Of course, the intermediate preset weight can also select other values ​​according to different user groups. In addition, the rice cooker is also set with a rice-to-water ratio. For example, the rice-to-water ratio can select any value within 1.1-1.5 according to different rice cooking modes. The intermediate preset water volume can be determined based on the intermediate preset weight and the rice-to-water ratio. In other words, the intermediate preset water volume corresponds to the intermediate preset weight and the rice-to-water ratio, that is, the intermediate preset water volume is the amount of water required for cooking rice when the amount of rice is equal to the intermediate preset weight and the rice-to-water ratio is set. In addition, the rice cooker is also provided with a maximum preset water volume. The maximum preset water volume corresponds to the maximum rice cooking volume and the rice-to-water ratio of the rice cooker, that is, the maximum preset water volume is the amount of water required for cooking rice when the amount of rice is equal to the maximum rice cooking volume and the rice-to-water ratio is set.

[0052] In actual use, the rice in the cooking cavity is first weighed. After the weighing is completed, the actual amount of rice in the cooking cavity is compared with the intermediate preset weight of the rice cooker. When the actual weight of the rice in the cooking cavity is less than or equal to the intermediate preset weight of the rice cooker, it is determined that the actual required amount of water is within the intermediate preset amount of water. Subsequently, the actual amount of water in the water tank 300 is compared with the intermediate preset amount of water. When the actual amount of water in the water tank 300 is greater than or equal to the intermediate preset amount of water, it is confirmed that the current amount of water in the water tank 300 can meet the needs of this rice cooking, and the water of the actual required amount of water is controlled to be injected into the cooking cavity. For example, a water injection pipe is provided between the cooking cavity and the water tank 300, and a water pump 400 and a flow meter are provided on the water injection pipe. When the actual amount of water in the water tank 300 is greater than or equal to the intermediate preset amount of water, the water pump 400 is controlled to be turned on so that the water in the water tank 300 is injected into the cooking cavity. When the flow meter detects that the amount of water injected into the cooking cavity reaches the actual required amount of water, the water pump 400 is turned off to stop injecting water into the cooking cavity.

[0053] Through this structural setting, the electric rice cooker is set with an intermediate preset weight, and the corresponding rice-water ratio is set in different modes, and the intermediate preset water volume is set corresponding to the intermediate preset weight and the rice-water ratio. In actual use, when the actual weight of the rice in the cooking cavity is less than or equal to the intermediate preset weight of the electric rice cooker, and the actual water volume in the water tank 300 is greater than or equal to the intermediate preset water volume, the water in the water tank 300 can be injected into the cooking cavity to cook rice without adding water. As a result, the number of unnecessary water adding operations by the user is reduced, and the user experience is greatly improved.

[0054] In one embodiment of the present invention, step S2 further includes: sending a water adding signal based on a state that the actual water volume in the water tank 300 is less than the intermediate preset water volume.

[0055] Specifically, when the actual weight of the rice in the cooking cavity is less than or equal to the intermediate preset weight of the rice cooker, it is determined that the actual required water volume is within the intermediate preset water volume. Subsequently, the actual water volume in the water tank 300 is compared with the intermediate preset water volume. When the actual water volume in the water tank 300 is less than the intermediate preset water volume, it is confirmed that the water in the water tank 300 cannot meet the demand for cooking rice this time, and a water adding signal is sent to prompt the user to perform a water adding operation. When the actual water volume in the water tank 300 reaches the maximum preset water volume, the water adding signal is stopped. Subsequently, the water pump 400 is controlled to be turned on so that the water in the water tank 300 is quantitatively injected into the cooking cavity.

[0056] In one embodiment of the present invention, before step S1, the method further includes:

[0057] S01: Based on the fact that the actual water volume in the water tank 300 is greater than or equal to the maximum preset water volume, injecting an actually required amount of water into the cooking cavity;

[0058] Based on the fact that the actual water volume in the water tank 300 is less than the maximum preset water volume, step S1 is initiated.

[0059] For example, in the actual water adding control process, first, the actual water volume in the water tank 300 is compared with the maximum preset water volume. When the actual water volume in the water tank 300 is greater than or equal to the maximum preset water volume, it indicates that within the maximum rice cooking volume range, the actual water volume in the water tank 300 can meet the water volume requirement for this rice cooking. Subsequently, the amount of rice in the cooking cavity is detected, and the actual amount of water required for this rice cooking is determined based on the rice-water ratio in the current operating mode, and the water pump 400 is started to inject the water required for this rice cooking from the water tank 300 into the cooking cavity for rice cooking.

[0060] When the actual amount of water in the water tank 300 is less than the maximum preset amount of water, it is necessary to start the step S1, specifically, compare the actual amount of water in the water tank 300 with the maximum preset amount of water. When the actual amount of water in the water tank 300 is less than the maximum preset amount of water, it is impossible to determine whether the current amount of water in the water tank 300 can meet the demand for cooking rice this time. At this time, the amount of rice in the cooking cavity is detected, and the actual amount of rice in the cooking cavity is compared with the intermediate preset weight of the rice cooker. When the actual weight of the rice in the cooking cavity is less than or equal to the intermediate preset weight of the rice cooker, it is determined that the actual required amount of water is within the intermediate preset amount of water. Subsequently, the actual amount of water in the water tank 300 is compared with the intermediate preset amount of water. When the actual amount of water in the water tank 300 is greater than or equal to the intermediate preset amount of water, it is confirmed that the current amount of water in the water tank 300 can meet the demand for cooking rice this time, and the water pump 400 is controlled to start to inject the actual required amount of water into the cooking cavity.

[0061] In one embodiment of the present invention, step S1 includes:

[0062] When the actual weight of the rice is less than or equal to the middle preset weight of the rice cooker, it is determined that the actually required water level is not higher than the middle preset water level.

[0063] In one embodiment of the present invention, the step S2 includes:

[0064] The float in the float level gauge 600 in the water tank 300 does not trigger the intermediate preset water level signal, and it is determined that the actual water volume in the water tank 300 is less than the intermediate preset water volume.

[0065] Further, in one embodiment of the present invention, based on the fact that the actual water volume in the water tank 300 is greater than or equal to the maximum preset water volume, the step of injecting the actually required water volume into the cooking cavity includes:

[0066] The actual water level in the water tank 300 is not lower than the maximum preset water level, and it is determined that the actual water volume in the water tank 300 is greater than or equal to the maximum preset water volume.

[0067] More specifically, in one embodiment of the present invention, the actual water level in the water tank 300 is not lower than the maximum preset water level specifically includes:

[0068] The float in the float level gauge 600 in the water tank 300 triggers the intermediate preset water level signal and the maximum preset water level signal simultaneously, to determine that the actual water level in the water tank 300 is not lower than the maximum preset water level.

[0069] For example, the water tank 300 of the rice cooker is usually a water tank 300 of fixed size and regular shape. For example, the water tank 300 can be a square water tank 300 or a cylindrical water tank 300. Based on the intermediate preset weight and the rice-to-water ratio, the intermediate preset water volume can be determined. Based on the intermediate preset water volume, the shape and size of the water tank 300, the corresponding intermediate preset water level can be determined. Based on the maximum amount of rice cooked by the rice cooker and the rice-to-water ratio, the maximum preset water volume can be determined. Based on the maximum preset water volume, the shape and size of the water tank 300, the corresponding maximum preset water level can be determined. Based on the actual weight of the rice in the cooking chamber and the rice-to-water ratio, the actual required water volume can be determined. Based on the actual required water volume, the shape and size of the water tank 300, the corresponding actual required water level can be determined.

[0070] That is, the relationship between the actual required water volume, the maximum preset water volume, and the intermediate preset water volume can be determined by comparing the water level in the water tank 300. It should be noted that the above embodiment is only an illustrative embodiment of the present invention and does not constitute any limitation to the present invention. For example, in other embodiments of the present invention, the relationship between the actual required water volume, the maximum preset water volume, and the intermediate preset water volume can also be determined by the weight of water in various states.

[0071] It should be emphasized here that the present invention does not limit the specific type of the detection device used to monitor the relationship between the actual water level and the intermediate preset water level and the maximum preset water level in the water tank 300. For example, the detection device includes but is not limited to a liquid level sensor or a float liquid level meter 600.

[0072] In one embodiment of the present invention, Figures 2 to 4As shown, the electric rice cooker is equipped with a water tank 300. A float level gauge is arranged in the water tank 300. The float level gauge includes a middle position detection float level gauge and a high position detection float level gauge. The middle position float level gauge includes a first float channel, a first float, a first reed switch and a middle position travel switch. The high position float level gauge includes a second float channel, a second float, a second reed switch and a high position travel switch. The first float channel and the second float channel are arranged in the water tank 300 at intervals along the vertical direction. The lower end of the first float channel is connected to the bottom of the water tank 300, and the upper end cover of the first float channel corresponds to the middle preset water level. The lower end of the second float is connected to the bottom of the water tank 300, and the upper end cover of the second float channel corresponds to the maximum preset water level. The middle position travel switch is correspondingly arranged at the middle preset water level, and the high position travel switch is correspondingly arranged at the maximum preset water level. The first float is installed in the first float channel, and the second float is installed in the second float channel. When the actual water level in the water tank 300 is lower than the middle preset water level, the middle travel switch and the high travel switch are both in the disconnected state. When the actual water level in the water tank 300 is between the middle preset water level and the maximum preset water level, the first float drives the first reed switch to trigger the middle travel switch. When the actual water level in the water tank 300 is greater than or equal to the maximum preset water level, the first float drives the first reed switch to trigger the middle travel switch, and the second float drives the second reed switch to trigger the high travel switch.

[0073] Triggering the middle stroke switch means triggering the middle preset water level signal, and triggering the high stroke switch means triggering the maximum preset water level signal.

[0074] In another embodiment of the present invention, the float level gauge includes a middle and high position detection float level gauge. The middle and high position float level gauge includes a float channel, an upper end cover, a lower end cover, a float, a reed switch, a middle position travel switch and a high position travel switch. The float channel is arranged in the water tank 300 and connected to the side wall of the water tank 300. The upper end cover and the lower end cover are respectively connected to the upper end and the lower end of the float channel. The upper end cover corresponds to the maximum preset water level, and the lower end cover corresponds to the middle preset water level. The middle position travel switch is arranged at the middle preset water level, and the high position travel switch is arranged at the maximum preset water level. The float is installed in the float channel. When the actual water level in the water tank 300 is lower than the middle preset water level, the middle position travel switch and the high position travel switch are both in the disconnected state. When the actual water level in the water tank 300 is between the middle preset water level and the maximum preset water level, the float drives the reed switch to trigger the middle position travel switch. When the actual water level in the water tank 300 is greater than or equal to the maximum preset water level, the float drives the reed switch to trigger the middle position travel switch and the high position travel switch.

[0075] In the actual control of water addition, the actual water level in the water tank 300 is first compared with the maximum preset water level of the water tank 300. When the middle stroke switch and the high stroke switch are triggered at the same time, it indicates that the actual amount of water in the water tank 300 is greater than or equal to the maximum preset amount of water. In this state, within the maximum rice cooking amount range, the actual amount of water in the water tank 300 can meet the water demand for rice cooking. At this time, the water pump 400 is controlled to be turned on so that the water in the water tank 300 is injected into the cooking cavity. When the flow meter detects that the amount of water injected into the cooking cavity reaches the actual required amount of water, the water pump 400 is turned off to stop injecting water into the cooking cavity.

[0076] When the actual water level in the water tank 300 can only trigger the middle stroke switch, it indicates that the actual amount of water in the water tank 300 is between the middle preset water volume and the maximum preset water volume. At this time, the amount of rice in the cooking cavity is detected, and the actual amount of rice in the cooking cavity is compared with the middle preset weight of the rice cooker. When the actual weight of the rice in the cooking cavity is less than or equal to the middle preset weight of the rice cooker, it is determined that the actual required water level is not higher than the middle preset water level. Subsequently, it is confirmed that the current actual amount of water in the water tank 300 can meet the needs of this rice cooking. The water pump 400 is controlled to turn on so that the water in the water tank 300 is injected into the cooking cavity. When the flow meter detects that the amount of water injected into the cooking cavity reaches the actual required amount of water, the water pump 400 is turned off to stop injecting water into the cooking cavity.

[0077] When the actual water level in the water tank 300 can only trigger the middle stroke switch, and the actual weight of the rice in the cooking chamber is greater than the middle preset weight of the rice cooker, it is impossible to determine whether the actual amount of water in the water tank 300 can meet the demand for cooking rice this time. In order to avoid the phenomenon of failure of cooking rice due to lack of water, a water adding signal is sent to remind the user to add water. The user adds water to the water tank 300 until the actual water level reaches the maximum preset water level, that is, the middle stroke switch and the high stroke switch are triggered at the same time. It should be understood that the remaining water in the water tank 300 after each cooking can be used for the next cooking.

[0078] In one embodiment of the present invention, before step S01, the method further includes:

[0079] Based on the detection result that the water tank 300 is not installed in place, an alarm signal is issued;

[0080] Based on the detection result that the water tank 300 is installed in place, step S01 is started.

[0081] That is to say, before the step of comparing the actual amount of water in the water tank 300 with the maximum preset amount of water, it is necessary to first detect the installation of the water tank 300. Only when the water tank 300 is installed in place, the subsequent steps are meaningful. The detection means for the installation of the water tank 300 include but are not limited to a pressure detection device or a weight detection device. When the water tank 300 is not installed in place, an alarm signal is issued to prompt the user to reinstall the water tank 300. When the water tank 300 is installed in place, the actual amount of water in the water tank 300 is compared with the maximum preset amount of water.

[0082] The embodiment of the second aspect of the present invention provides a water adding control device for an electric rice cooker, comprising:

[0083] Weighing module 700, used to detect the actual weight of rice;

[0084] A water volume monitoring module, used to monitor the actual water volume in the water tank 300;

[0085] The control module 500 is used to determine that the actual required water volume is within the intermediate preset water volume based on the actual weight of the rice being less than or equal to the intermediate preset water volume of the rice cooker, and to inject the actual required water volume into the cooking cavity based on the actual water volume in the water tank 300 being greater than or equal to the intermediate preset water volume.

[0086] For example, the weighing module 700 is specifically used to detect the actual weight of rice in the rice cooker cavity. In essence, the water volume monitoring module is used to monitor the relationship between the actual water volume in the water tank 300 and the intermediate preset water volume and the maximum preset water volume. The weighing module 700 and the water volume monitoring module are both connected to the control module 500. The control module 500 can receive signals from the weighing module 700 and the water volume monitoring module to determine that the actual required water volume is within the intermediate preset water volume based on the actual weight of the rice being less than or equal to the intermediate preset weight of the rice cooker, and based on the state that the actual water volume in the water tank 300 is greater than or equal to the intermediate preset water volume, inject the actual required water volume into the cooking cavity.

[0087] The embodiment of the third aspect of the present invention further provides an electric rice cooker, which adds water according to the electric rice cooker water adding control method as described above or includes the electric rice cooker water adding control device as described above.

[0088] In addition, if Figures 2 to 5 As shown, the electric rice cooker also includes a rice cooker body 100, a rice cooker cover 200, a water tank 300, a water pump 400, and a flow meter. A cooking cavity is arranged in the rice cooker body 100, and a weighing module 700 is arranged at the bottom of the cooking cavity. A water tank 300 is arranged beside the rice cooker body 100. A water injection port is arranged on the rice cooker cover 200. The water tank 300 is connected to the water injection port through a water injection pipe, and the water injection port is connected to the cooking cavity. A water pump 400 and a flow meter are arranged on the water injection pipe. A float liquid level gauge 600 is arranged in the water tank 300.

[0089] Furthermore, in the electric rice cooker provided by the present invention, since water addition is controlled by the electric rice cooker water addition control method as described above, the electric rice cooker also has the advantages as described above.

[0090] In other embodiments of the present invention, an electronic device is also provided, the electronic device comprising a processor, a communication interface, a memory and a communication bus. The processor, the communication interface and the memory communicate with each other via the communication bus.
