Electric range to prevent fire accidents caused by pet power input {ELECTRICRANGE FOR PREVENTING FIRE ACCIDENT BY POWER INPUT OF PETS}

The present invention relates to an electric range that determines whether or not to operate depending on whether there is an abnormal power input from a companion animal.

Recently, accidents in which electric ranges malfunction due to abnormal power input by pets have occurred frequently. Especially in the absence of the user, such malfunction is very likely to lead not only to a fire accident but also to the death of the pet.

In order to prevent this situation, technology has been introduced to block malfunction of the electric range by determining whether there is an abnormal power input depending on the input to various sensors of the electric range.

However, since it is difficult to accurately determine whether the power input is abnormal based on fragmentary characteristics such as sensor input, the problem of the electric range still malfunctioning despite the abnormal power input has not been solved.

According to this, since the horizontal movement path of the object can be easily determined, it is possible to quickly determine whether there is an abnormal power input.

The control unit determines whether the generation path corresponds to the preset erroneous input path based on the fact that the first input signal and the at least one second input signal are generated together within a preset time range.

According to this, the accuracy of determining whether the target has an abnormal power input can be further improved.

It further includes an audio output unit, wherein the control unit controls the audio output unit to output a preset audio corresponding to the target when it is determined that the determined occurrence path corresponds to the preset erroneous input path with respect to the target. do.

According to this, the target can be quickly eradicated, and abnormal power input can be prevented in the future.

FIG. 3 shows an example of determining whether the electric range of FIG. 1 corresponds to a generation path and an incorrect input path, and FIG. 4 shows an example of a normal input path by a user.

Hereinafter, for convenience of explanation, in a state in which the power of the second cooking surface 72 of the electric range 1 is turned off, the cat enters the lower right part of the upper surface 21 and moves toward the second power sensor 142. -Assume a situation where the second power sensor 142 is touched while walking in the Y-axis direction.

When a plurality of auxiliary sensors 16 are arranged horizontally spaced apart on the upper surface 21, as the cat moves horizontally in the -Y axis direction and sequentially touches two or more adjacent auxiliary sensors 16, two or more auxiliary sensors Two or more second input signals may be sequentially input to (16). The control unit 9 may identify a path moving horizontally from the lower right portion of the upper surface 21 toward the second power sensor 142 based on two or more second input signals input by the cat's touch.

The movement path identified in this way is different from the movement path 64 shown in FIG. 4. The movement path 64 is a normal input path 60 by the user 10, and is a movement path approaching in the -Z-axis direction toward the second power sensor 142 from a position spaced upward from the upper surface 51. Includes.

The control unit 9 may determine the identified horizontal movement path as the generation path 24 of the first input signal and the second input signal. In addition, the control unit 9 identifies a movement path including a straight line, diagonal line, curve, etc. that moves horizontally from the lower left part, upper left part, upper right part, etc. of the upper surface 21 toward the second power sensor 142. And, this may be judged as the generation path 24 of the first input signal and the second input signal.

The control unit 9 determines whether the determined occurrence path 24 corresponds to the incorrect input path 50. The incorrect input path 50 may include a plurality of horizontal movement paths 54 through which the cat can move on the virtual upper surface 51 corresponding to the upper surface 21. The multiple horizontal movement paths 54 may be different from those of other companion animals depending on the unique species characteristics of cats. The plurality of horizontal movement paths 54 are virtual having various shapes such as straight lines, diagonals, and curves from the lower left, lower right, upper left, and upper right parts of the virtual upper surface 51 to the virtual second power sensor 182. It may include a horizontal movement path.

Since a plurality of horizontal movement paths 54 can be classified and prepared for each virtual power sensor 181 and 182, the control unit 9 controls each virtual power source when there is a first input signal to the second power sensor 182. Among the plurality of horizontal movement paths 54 provided for each sensor 181, 182, only the plurality of horizontal movement paths 54 corresponding to the second virtual power sensor 182 are identified, and the determined occurrence path 24 is divided into a plurality of horizontal movement paths 54. It can be determined whether it corresponds to one of the horizontal movement paths 54.

Whether or not there is a correspondence between the occurrence path 24 and the erroneous input path 50 can be determined by considering at least one factor among the direction, distance, speed, and shape between the paths. Since the two may not necessarily be the same, the control unit 9 can determine whether or not a plurality of factors are similar. For example, if the similarity between the shapes of the two paths is greater than or equal to a preset threshold, it may be determined that the two paths correspond. In addition, the control unit 9 can determine whether the two paths correspond in various ways. For example, if a predetermined number or more of a plurality of factors are similar, the control unit 9 can identify that the two paths correspond.

If it is determined that the occurrence path 24 corresponds to the incorrect input path 50, the control unit 9 ignores the power input command generated by the first input signal from the second power sensor 142. That is, the control unit 9 determines that the power input to the second power sensor 142 is an abnormal power input from a cat rather than a user, and prevents the electric range 1 from operating to maintain the power-off state. .

In this way, the control unit 9 according to this embodiment can utilize the erroneous input path 50 for the plurality of horizontal movement paths 54 when determining whether or not it is an abnormal power input, thereby improving the accuracy and speed of judgment. This can be done, and through this, a safer environment for using the electric range (1) can be created.

According to various embodiments, the incorrect input path 50 may be stored in the storage unit 8, the server 3, or a plurality of external devices 5. When the incorrect input path 50 is stored in the server 3 or a plurality of external devices 5, the control unit 9 uses the server 3 or a plurality of external devices 5 to determine whether it corresponds to the occurrence path 24. Information about the incorrect input path 50 can be received from (5).

According to this, since there is no need to directly store information about the incorrect input path 50 depending on the situation, resources can be utilized efficiently.

According to various embodiments, when the first input signal and at least one second input signal are generated together within a preset time range (ts), the control unit 9 determines the control between the generation path 24 and the erroneous input path 50. You can decide whether to respond or not. The time range (ts) can be determined according to the species characteristics of the object (4). As an example, the time range (ts) may be determined in various ways based on the distance from the lower right portion to the second power sensor 142 and the average walking or running speed of the cat.

For convenience of explanation, it is assumed that the time range (ts) is set to 10 seconds. 10 seconds may have been set considering the species characteristics of cats. The control unit 9 determines whether the time from the time (tb) at which the second input signal of the auxiliary sensor 16 is generated to the time (ta) at which the first input signal of the second power sensor 142 is generated is within 10 seconds. The time (tb) at which the second input signal occurs may correspond to the second input signal generated first among at least one second input signal.

If it is within 10 seconds, the control unit 9 determines whether there is a correspondence between the occurrence path 24 and the incorrect input path 50, and depending on the correspondence, for example, the cat enters the upper surface 21 and walks while the auxiliary sensor Considering that (16) and the second power sensor 142 have been touched, it can be determined that the power input to the second power sensor 142 is abnormal.

On the other hand, if it is not within 10 seconds, for example, a second input signal is generated by the user 10 or the cooking utensil 2 during the cooking preparation process, and after 10 seconds, the user 10 uses the cooking utensil 2. Considering that the second power sensor 142 is touched for heating, the control unit 9 may not determine whether there is a correspondence between the occurrence path 24 and the erroneous input path 50.

In this way, according to the present embodiment, considering the correlation regarding the occurrence time between the first input signal and at least one second input signal, it is determined whether a judgment between the occurrence path 24 and the erroneous input 50 is necessary. Therefore, the accuracy and speed of judgment regarding abnormal power input can be further improved.

Figure 5 shows an example in which the electric range of Figure 1 performs follow-up measures in response to the power input of the target.

If the control unit 9 determines that the power input to the power sensor 14, for example, the power input to the second power sensor 142, is an abnormal power input by the target 4, the control unit 9 determines a preset power input in response to the abnormal power input. The audio output unit 19 is controlled to output audio 43. The preset audio 43 may have audio characteristics that the subject 4 can hear, and may have audio characteristics that the subject 4 does not prefer. As an example, the preset audio 43 has a frequency band that cats can hear, and may be output as the cry of an animal that is a natural enemy that the cat dislikes.

In this way, according to this embodiment, the target 4 can be quickly defeated, and abnormal power input can be prevented in the future.

According to various embodiments, if it is determined that the control unit 9 is an abnormal power input by the target 4, it can transmit preset information corresponding to the abnormal power input to a plurality of external devices 5. The plurality of external devices 5 may include a smartphone of the user 10, and the smartphone of the user 10 may detect the object 4 based on information transmitted from the electric range 1. ) Information (45) indicating that it exists above or that an abnormal power input has occurred due to the object (4) can be displayed. In addition, the control unit 9 can transmit various notification information, warning information, etc. to enable the smartphone to display various notification information, warning information, etc.

In this way, according to this embodiment, the user 10 can quickly take action, thereby preventing abnormal power input in the future.

Above, the present invention has been described in detail through preferred embodiments, but the present invention is not limited thereto and may be implemented in various ways within the scope of the patent claims.
