  Embodiments of a heating cooker according to the present invention will be described below with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Reference form 1)
Hereinafter, a reference embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a reference form of the present invention.

  The heating cooker of FIG. 1 has a heating unit 1 for heating a load such as a pan, and the operation display unit 2 sets an operation setting state of the heating unit 1 and performs a display corresponding to the setting state. Etc., which are composed of LEDs or LCDs.

  The operation of the above configuration will be described. When the user operates a switch or the like of the operation display unit 2, the operation display unit 2 outputs an operation start or set thermal power signal to the heating unit 1. Receiving this, the heating unit 1 starts the heating operation, or performs an operation such as changing the setting of the heating power for the heating operation.

  At the same time, the operation display unit 2 displays the set state of each heating unit. At this time, since the operation display unit 2 has an operation display element constituted by an LED or an LCD, the user can easily visually recognize in what setting state the heating unit 1 is operating. .

  For example, when heating the heating unit 1 and heating a load such as a pan, a heating power setting key 4 configured by the heating key 3 of the operation display unit 2 shown in FIG. 1, the heating power up key 4 a, and the heating power down key 4 b is used. Thus, the heating start and stop can be set every time the heating key 3 is pressed, and the heating heating power is changed by pressing the heating power up key 4a or the heating power down key 4b during the heating operation. Also, the setting of the heating thermal power can be changed in five stages: thermal power “5” 2500 W, thermal power “4” 2000 W, thermal power “3” 1500 W, thermal power “2” 1000 W, and thermal power “1” 500 W. . At the same time, the set state is displayed by turning on / off the heating display element 5 indicating the heating state of the heating unit and the heating power display element 6 indicating the heating power setting state. The heating display element 5 indicating the heating state is turned on when the heating operation is being performed, and is turned off when the heating is stopped. In addition, the thermal power display element 6 indicating the thermal power setting state has an LED corresponding to the thermal power that has been set, such as “5”, “4”, “3”, “2”, “1” in the present embodiment. Lights up.

  In the above configuration, in order to heat the heating unit 1, by pressing the heating key 3 for a first predetermined time (for example, 0.2 seconds), the operation display unit 2 receives the input, and the heating unit 1 is heated. While outputting an operation signal, the heating display element 5 indicating the heating state is turned on, and the initial heating power “3” of the heating unit 1 is displayed on the heating power display element 6 indicating the heating power setting state. That is, the operation display unit 2 receives the input when the heating key 3 is pressed for a first predetermined time, and the heating unit 1 that has received the heating operation signal from the operation display unit 2 sets the initial heating power to “3”. To start the heating operation.

  Further, in order to change the set thermal power of the heating unit 1, the operation display unit 2 accepts the input by pressing the thermal power up key 4a or the thermal power down key 4b for a first predetermined time (for example, 0.2 seconds). In addition to outputting a heating power one-step change signal to the heating unit 1, the heating power display element 6 indicating the heating power setting state is changed to the heating power “4” after changing the heating unit 1 (when the heating power up key 4a is pressed) or “2”. (When the thermal power down key 4b is pressed) is displayed. That is, the operation display unit 2 receives the input when the heating power setting key 4 is pressed for a first predetermined time, and receives the heating power one-step change signal (increase or decrease) from the operation display unit 2. Changes the heating power to “4” (when the operation display unit 2 receives the heating power up key 4a) or “2” (when the operation display unit 2 receives the heating power down key 4b), Continue operation.

In order to change the setting thermal power of the heating unit 1 while the heating unit 1 is operating at the set thermal power “5” (the thermal power “5” is displayed on the thermal power display element 6 indicating the thermal power setting state), By pressing the thermal power down key 4b for a second predetermined time longer than the first predetermined time (for example, 0.3 seconds or longer), the operation display unit 2 receives the input, and the heating unit 1 receives a plurality of thermal power steps. While outputting a decrease signal (for example, a two-stage change signal), the heating unit 1 is connected to the thermal power display element 6 indicating the thermal power setting state.
“3” is displayed. That is, the operation display unit 2 accepts the input when the thermal power down key 4b is pressed for a second predetermined time or more, and the heating unit 1 that receives the thermal power multi-step decrease signal from the operation display unit 2 The heating power is changed to “3” and the heating operation is continued. However, in order to change the set thermal power of the heating unit 1 while the heating unit 1 is operating at the set thermal power “1” (the thermal power “1” is displayed on the thermal power display element 6 indicating the thermal power setting state), Even if the thermal power up key 4a is pressed for a second predetermined time longer than the first predetermined time (for example, 0.3 seconds or longer), the one-stage change is maintained, and the thermal power down key 4b is pressed for a long time. Furthermore, it does not change more than one step. Thus, by determining the process of changing the heating power of the heating unit 1 according to the time during which the heating power setting key 4 is pressed, the user can quickly change the heating power setting without repeating the same operation. Therefore, usability can be improved while maintaining safety.

  At this time, a stage for changing the thermal power is set according to the length of time that the thermal power down key 4b is pressed for a long time. That is, when the thermal power down key 4b is pressed for a second predetermined time or longer (for example, 0.3 seconds or longer), the thermal power setting is reduced by a plurality of stages. 2 steps, 3 steps if 0.4 seconds or more and less than 0.5 seconds, 4 steps if 0.5 seconds or more, the operation display unit 2 is pressed when the thermal power down key 4b is pressed. Detecting the current time, and determine the stage of firepower to change according to the time. Thus, by determining the stage of the thermal power to be changed according to the time during which the thermal power down key 4b is pressed, the user can quickly change the thermal power with fewer operations and improve the operability. Can do.

  Furthermore, only when the thermal power down key 4b is received for a second predetermined time or longer, this function can be enabled or disabled by the selection key 7 that can select whether the thermal power of the heating unit 1 is reduced by a plurality of levels. You can choose what to do. If it is in the enabled state, this function is enabled. When the thermal power down key 4b is received for a second predetermined time or more, the function of reducing the thermal power of the heating unit 1 by a plurality of levels operates. Even if the key 4b is received for the second predetermined time or longer, the function of reducing the heating power of the heating unit 1 by a plurality of levels does not operate. In this way, since the user can easily switch between enabling and disabling this function, the user's careless operation can be prevented.

  Further, only when the thermal power down key 4b is received for the second predetermined time or longer, the switching display element 8 displays whether the function of further reducing the thermal power of the heating unit 1 by one step or more is valid or invalid. I do. This makes it easy for the user to visually understand whether the function is valid or invalid.

  As described above, according to the embodiment of the present invention, the thermal power setting key 4 that changes the thermal power level only by one level is provided with the added value of changing the thermal power one or more levels in the case of a long press. By changing the operation of the same key without providing a key, the user-friendliness can be improved without complicating the operation display unit 2.

(Embodiment 1)
Embodiments of the present invention will be described below with reference to the drawings. The basic configuration of the heating cooker is the same as the block diagram of the reference form 1 shown in FIG.

In order to heat the heating unit 1, by pressing the heating key 3 for a first predetermined time (for example, 0.2 seconds), the operation display unit 2 receives the input and outputs a heating operation signal to the heating unit 1. At the same time, the heating display element 5 indicating the heating state is turned on, and the initial heating power “3” of the heating unit 1 is displayed on the heating power display element 6 indicating the heating power setting state. That is, the operation display unit 2 receives the input when the heating key 3 is pressed for a first predetermined time (for example, 0.2 seconds), and the heating unit 1 that receives the heating operation signal from the operation display unit 2 Then, the heating operation is started at the initial heating power “3”.

  Further, in order to change the set thermal power of the heating unit 1, the operation display unit 2 accepts the input by pressing the thermal power up key 4a or the thermal power down key 4b for a first predetermined time (for example, 0.2 seconds). In addition to outputting a heating power one-step change signal to the heating unit 1, the heating power display element 6 indicating the heating power setting state is changed to the heating power “4” after changing the heating unit 1 (when the heating power up key 4a is pressed) or “2”. (When the thermal power down key 4b is pressed) is displayed. That is, the operation display unit 2 accepts the input when the heating power setting key 4 is pressed for a first predetermined time (for example, 0.2 seconds), and the operation display unit 2 receives a heating power one-step change signal (increase or decrease). ), The heating unit 1 receives the changed heating power “4” (when the operation display unit 2 receives the heating power up key 4a) or “2” (when the operation display unit 2 receives the heating power down key 4b). Change the heating power to continue heating operation.

  In order to change the setting thermal power of the heating unit 1 while the heating unit 1 is operating at the set thermal power “5” (the thermal power “5” is displayed on the thermal power display element 6 indicating the thermal power setting state), By pressing the thermal power down key 4b for a second predetermined time longer than the first predetermined time (for example, 0.3 seconds or longer), the operation display unit 2 accepts the input, and the heating unit 1 receives one step of thermal power. While outputting a decrease signal, the thermal power “4” after the change of the heating unit 1 is displayed on the thermal power display element 6 indicating the thermal power setting state. Furthermore, if the thermal power down key 4b is continuously pressed (for example, 0.8 seconds or longer), the operation display unit 2 accepts the input, and the heating unit 1 outputs a thermal power one-step decrease signal again. This is performed at regular intervals (for example, at intervals of 0.5 seconds) while the thermal power down key 4b is continuously pressed. That is, the operation display unit 2 receives the input when the thermal power down key 4b is pressed for a second predetermined time or longer (for example, 0.3 seconds or longer), and receives a thermal power one-step decrease signal from the operation display unit 2. The heating unit 1 performs a process of reducing the heating power by one step and continuing the heating operation at regular intervals (for example, at intervals of 0.5 seconds). Thus, by determining the process of changing the heating power of the heating unit 1 according to the time during which the heating power setting key 4 is pressed, the user can quickly change the heating power setting without repeating the same operation. Therefore, usability can be improved.

  At this time, an interval for changing the thermal power is set according to the length of time that the thermal power down key 4b is pressed for a long time. That is, if the thermal power down key 4b is pressed for a second predetermined time or longer (for example, 0.3 seconds or longer), the thermal power setting is lowered by one step, and further, the long pressing of the thermal power down key 4b continues for a second predetermined time or longer. If it continues (for example, 0.8 seconds or more), the process of lowering the thermal power setting by one step is performed again. However, the longer the time of pressing the thermal power down key 4b, the lower the thermal power setting by one step. Reduce the interval. For example, if it is pressed for 0.3 seconds or longer, the one-step heating power is reduced, and if it continues for more than 0.8 seconds (interval 0.5 seconds), the one-step heating power is decreased again, and further 1.2 seconds (interval 0) (4 seconds), the operation display unit 2 detects the time during which the thermal power down key 4b is pressed, and determines an interval for changing the thermal power according to the time. However, in order to change the set thermal power of the heating unit 1 while the heating unit 1 is operating at the set thermal power “1” (the thermal power “1” is displayed on the thermal power display element 6 indicating the thermal power setting state), Even if the thermal power up key 4a is pressed for a second predetermined time longer than the first predetermined time (for example, 0.3 seconds or longer), the one-stage change is maintained, and the thermal power down key 4b is pressed for a long time. Furthermore, it does not change more than one step. In this way, by determining the interval for changing the thermal power according to the time during which the thermal power down key 4b is pressed, the user can quickly change the thermal power with fewer operations and improve the operability. Can do.

Furthermore, only when the thermal power down key 4b is received for the second predetermined time or longer, the function can be enabled by the selection key 7 that can select whether the thermal power of the heating unit is further reduced by one step or more. You can choose to disable it. If it is in the valid state, this function is valid, and when the thermal power down key 4b is received for the second predetermined time or more, the function to lower the thermal power of the heating unit by a plurality of stages operates. Even if 4b is received for the second predetermined time or more, the function of further reducing the heating power of the heating unit by one or more steps does not operate. In this way, since the user can easily switch between valid and invalid of this function, the user's unexpected operation can be prevented.

  Further, only when the thermal power down key 4b is received for the second predetermined time or longer, the switching display element 8 displays whether the function for further reducing the thermal power of the heating unit by one or more stages is valid or invalid. Do. This makes it easy for the user to visually understand whether the function is valid or invalid.

  As described above, according to the present embodiment, the thermal power setting key 4 for changing the thermal power level only by one level is provided with the added value of changing the thermal power by one or more levels when long-pressed. By changing the operation of the same key without providing a key, the user-friendliness can be improved without complicating the operation display unit 2.

  In this embodiment, the case where there is one heating unit is described, but even when there are two or more heating units, the operation display unit corresponding to each heating unit detects a long press of the heating power setting key. A similar effect can be obtained by determining the stage of the thermal power to be changed.

  The cooking device of the present invention is constructed by a system using a microcomputer or the like, and can improve the operability without complicating the key arrangement of the operation display unit in the cooking device having the operation display unit. Therefore, the present invention can be applied not only to a household cooking device but also to a cooking device having a business operation display unit used in a restaurant kitchen or the like.
