Microwave device with prompt function

The present invention relates to a food heating device, and more particularly to a microwave device having a prompting function.

In recent years, microwave ovens are often used to heat food in kitchens and supermarkets. However, it usually takes tens of seconds or even minutes to heat food in a microwave oven. Therefore, users usually use the above time to handle other affairs or temporarily leave, although the microwave ends the microwave. When the user temporarily leaves or is busy with other matters, the user often forgets to take out the food because he or she does not hear the prompt or hear the prompt, and then forgets to take out the food, especially when the microwave is just finished. There will be a warning sound, and it is not always possible to remind the user that the food has been heated up, causing the food in the microwave oven to be cooled again because it has not been taken out, so the existing microwave oven still needs to be improved.

Therefore, the object of the present invention is to provide a microwave device having a prompting function that can prompt the user to take out an item at a time.

Therefore, the novel microwave device with prompt function is suitable for detecting whether an item has been taken out, and comprises: a microwave unit, a weight sensing unit, and a processing unit. The microwave unit includes a microwave oven that can be activated to carry out microwaves, and a tray located in the microwave oven for holding articles. The weight sensing unit is disposed under the tray to carry the tray and to measure the weight of the tray and the items on the tray. The processing unit is connected to the microwave oven and the weight sensing unit. The processing unit includes a storage module, a prompting module, a detecting module, and a determining module. The detecting module is At the time of startup, the weight measured by the weight sensing unit stores an initial weight in the storage module, and the determining module compares the initial weight stored in the microwave module with the initial weight stored in the microwave module. The weight of the sensing unit currently measured to determine whether the tray holds the item, and when the item is judged to be on the tray, the prompting module is driven to issue a prompt message.

The function of the present invention is that, by the cooperation of the weight sensing unit and the processing unit, when the user does not take out the item, the prompt message can be sent to prompt the user to take out the item until the user takes out the item. Stop sending this message, so that the user can be reminded to take out the food from time to time to avoid the food being cold again and quite humanized.

Referring to FIG. 1, FIG. 2 and FIG. 3, an embodiment of the present invention has a prompting function of a microwave device, which is suitable for detecting whether an item 900 has been taken out, including a microwave unit 1, a weight sensing unit 2, and a Processing unit 3.

The microwave unit 1 includes a microwave oven 11 that can be activated to carry out microwaves, and a tray 12 located in the microwave oven 11 for holding the articles 900. The microwave oven 11 is a microwave oven 11 which is generally used in the market. Since the type of the microwave oven 11 is numerous and is a conventional technique, it is not the focus of the present invention, and therefore will not be described in detail herein.

The weight sensing unit 2 is disposed under the tray 12 to carry the tray 12 and measure the weight of the tray 12 and the article 900. Since the article 900 is placed above the tray 12, the The weight measured by the weight sensing unit 2 is the total weight of the article 900 and the tray 12. In the implementation, the weight sensing unit 2 can measure the weight by using a resistance strain type, a photoelectric type, a hydraulic type, an electromagnetic force type, a capacitive type and the like, and is not the focus of the present invention because of various types and is a conventional technology. Therefore, it will not be detailed.

The processing unit 3 is connected to the microwave oven 11 and the weight sensing unit 2. The processing unit 3 includes a storage module 31 for storing data, a prompt module 32, a detecting module 33, and a determining module. Group 34.

The prompt module 32 can be driven to send a prompt message. In the embodiment, the prompt module 32 is an electronic component that can emit sound such as a buzzer, but in practice, the prompt module 32 can also be embedded. An LED that is exposed to the outer surface of the microwave oven 11 and emits colored light, or an electronic component that can simultaneously emit light and sound, is not limited to this embodiment.

The detecting module 33 stores the initial weight of the weight measured by the weight sensing unit 2 on the storage module 31 when the microwave oven 11 is activated to perform microwaves, that is, the initial weight is representative. The total weight of the article 900 and the tray 12 at the beginning of the microwave.

The determining module 34 compares the initial weight stored in the storage module 31 with the weight currently measured by the weight sensing unit 2 when the microwave oven 11 ends the microwave to determine whether the tray 12 is filled with The item 900. In this embodiment, the determination module 34 has an error value built therein. The determination module 34 compares the initial weight stored by the storage module 31 with the current weight measured by the weight sensing unit 2. When the difference between the initial weight and the weight currently measured by the weight sensing unit 2 is less than the error value, the weight currently measured by the weight sensing unit 2 includes the tray 12 and the article 900. The total weight, therefore, it is judged that the article 12 is filled with the article 900; when the difference between the initial weight and the weight measured by the weight sensing unit 2 is greater than the error value, it represents the weight sensing The weight currently measured by unit 2 contains only the weight of the tray 12, so it is judged that the article 900 is not contained on the tray 12.

It should be noted that, in this embodiment, the error value is built in the determining module 34 to prevent the item 900 from slightly changing in weight due to evaporation or spillage of water after the microwave. However, in practice, the determination is made. The module 34 may not have the built-in error value. In this case, the determining module 34 compares the initial weight with the weight currently measured by the weight sensing unit 2, and the initial weight and the weight. When the weight measured by the sensing unit 2 is the same, it is determined that the article 12 is filled with the article 900; when the initial weight is different from the weight currently measured by the weight sensing unit 2, the tray is judged to be The article 900 is not contained on the 12, and is not limited to the embodiment.

After determining that the article 900 is placed on the tray 12, the determining module 34 periodically drives the prompting module 32 to issue the prompt message every time interval, and determines that the tray 12 is not filled. When the item 900 is used, the initial weight stored by the storage module 31 and the weight currently measured by the weight sensing unit 2 are stopped, and the prompting module 32 is stopped to issue the prompt message, and the prompt message is also cleared. The initial weight stored by the storage module 31. In practice, the determining module 34 may not clear the initial weight stored in the storage module 31, and the detecting module 33 overwrites the original initial weight with a new initial weight when the microwave oven 11 is started next time. .

When the microwave device with the prompt function is used, the user first places the article 900 on the tray 12, and the weight measured by the weight sensing unit 2 is the total weight of the tray 12 and the article 900. The user then activates the microwave oven 11. When the microwave oven 11 is activated, the processing unit 3 stores the weight measured by the weight sensing unit 2, that is, the initial weight.

When the microwave oven 11 ends the microwave, the processing unit 3 determines whether the article is contained in the tray 12 according to the initial weight and the weight measured by the weight sensing unit 2, when the user does not take out the item. At 900 o'clock, the processing unit 3 can determine that the tray 12 is filled with the item 900, and the reminder module 32 is prompted to send the prompt message every time the interval is timed to remind the user to take out the item 900 in the microwave oven 11. . Until the user removes the item 900 by the reminder message or consciously, the processing unit 3 can determine that the item 900 is not contained in the tray 12, and stops driving the prompt module 32 to issue the prompt message.

It is worth mentioning that the determining module 34 can also be designed to continuously drive the prompting module 32 to send the prompt message when determining that the article 900 is placed on the tray 12 until it is determined that the tray 12 is not When the item 900 is placed, the prompting module 32 is stopped to send the prompt message, so that the user can be more actively reminded that the user is reminded to remove the item 900 in the microwave oven 11 by the user. The examples are limited.

In summary, the present invention has a prompting function of the microwave device. By the cooperation of the weight sensing unit 2 and the processing unit 3, when the user does not take out the item 900, the prompt message is periodically issued to prompt the user. The item 900 is taken out until the user takes out the item 900, and the prompt message is stopped. In this way, the user can be reminded to take out the food at any time to prevent the food from being cooled again, and is quite humanized, so it can be achieved. The purpose of this new type.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
