Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to the structure of an operation section such as an operation panel of a microwave oven.

0002

[Conventional technology]

The operation panel section 3 of a conventional microwave oven has a heating chamber 2, for example, as shown in FIG. installed on the front side of one side of the main body of the microwave oven 1 equipped with the heating chamber 2. . The operation panel section 3 has, for example, as shown in FIG. There are 5 types of food such as "warming milk", "sake can", "preparation of leafy vegetables", "preparation of root vegetables", etc. Automatic heating switch group (automatic Heating switch operation key) 12 and cookies such as "sweets (3 types)" and "cooking (6 types)" Automatic heating switch group 14 that corresponds to the operation menu centered on King heating, etc. Various automatic heating switches, ``Microwave high'', ``Microwave low'', ``Thaw perishables'', ``Grill'' Manual heating switch with operation menus such as ``Full'', ``Oven'', ``Simmered'', ``Fermentation'', etc. Group 13, furthermore, start button switch 15, cancel button switch 16, Temperature control switch 18 for oven, timer knob (combined for gram and amount adjustment) 17, table A wide variety of switch operation keys, operation members, display parts, etc. They are arranged in a concentrated manner. The number of operation menus and operation functions mentioned above are as follows: With the recent trend towards higher functionality of microwave ovens, the number of microwave ovens tends to increase further. The result As a result, the concentration density of operation keys on the operation panel section 3 is even higher than that shown in the figure. It is becoming. Therefore, when you try to actually perform the operation, the operation keys you need The problem is that it is difficult to find.

0003 By the way, in the structure of the conventional general operation panel section 3 described above, it is clear from the structure of FIG. In other words, the door 4 for sealing the heating chamber 2 simply closes the front opening of the heating chamber 2. The door 4 and the operation panel section 3 are completely separated. It is something different. And the front side part of door 4 with a large space is It is not always used effectively.

0004 Therefore, for example, various operation switch groups ( A part of the operation key group) 12, 13, 14, 15, 16 is moved to the front part of the door 4 and separated. It is also being considered in some cases to install them in a scattered manner and configure them as two operation panel sections. So If you do this, even if the number of operation keys increases, you can still use the operation panel on the microwave oven main unit. Since the concentration density of the operation members on the side of the key section 3 decreases, the number of operation keys that are required will decrease accordingly. While it has become easier to find, it has also made it possible to respond to a further increase in the number of operation keys. The benefits are great in that respect.

[0005]

[Problem that the idea aims to solve]

However, among the wide variety of operation keys listed above, there are only a few that are commonly used in ordinary homes. There are not many particularly frequently used operation keys used for limited to things.

[0006] Therefore, even if operation keys are provided on the front side of the door 4, they cannot be used. Unless the installation structure is designed with frequency in mind, there is little point in installing it, and it is originally a product that is used frequently. is installed on the operation panel section 3 on the microwave oven main body side behind the door 4. There is a problem that the door 4 needs to be opened and closed every time the door 4 is opened and closed, which makes the operation more inconvenient.

[0007] In addition, as mentioned above, a structure is adopted in which the operation key itself is installed directly on the door 4 side. In this case, since the door 4 is originally opened and closed as described above, the operation key The electrical connection and wiring structure between the control unit and the microwave oven main unit are complicated. New problems arise, such as increased costs and higher costs.

[0008]

[Means to solve the problem]

This invention was made with the purpose of solving the above problems. For example, as shown in FIGS. 1 to 3, the microwave oven main body 1a covered by the door 4 All operation menu keys 12a to 12e, 13a to the microwave oven are located in the first position on the side. 13h, 14a to 14g, 16, and the door 4 corresponding to the first position. An operation menu key is provided on the front side of the microwave oven body 1a at the first position. Particularly frequently used operations among 12a to 12e, 13a to 13h, 14a to 14g, and 16 Operation menu display sections 32a to 32e displaying menus are provided, and the four doors mentioned above are provided. Display the corresponding power on the body using the display on the operation menu display sections 32a to 32e as indicators. Press the corresponding operation menu keys 12a to 12e in the first position on the child microwave main body 1a side to the door. It is characterized by having internal operation members 31, 31, etc. that are turned on through the other side. be.

[0009]

[Effect]

As described above, in the structure of the operation section of the microwave oven of the present invention, the operation section is covered by the door 4. All operation menu keys 1 of the microwave oven are located in the first position on the side of the microwave oven body 1a. 2a to 12e, 13a to 13h, 14a to 14g, and 16 are arranged, while in the first position Provided on the front side of the corresponding door 4 at a first position on the side of the microwave oven main body 1a. Especially among the operation menu keys 12a to 12e, 13a to 13h, 14a to 14g, and 16 Operation menu display sections 32a to 32e displaying frequently used operation menus are provided. , the display of the operation menu display sections 32a to 32e on the main body of the door 4 is used as an indicator. corresponding operation menu keys 12a~ in the first position on the microwave oven main body 1a side. Consisting of internal operating members 31, 31, etc. for turning on 12e through the door body. has been done.

0010 Therefore, when the door 4 is closed, operations that are not used on a daily basis and are used infrequently. The operation menu keys 13a to 13h, 14a to 14g, and 16 are operated by the door 4 as shown in Figure 2. It is hidden and cannot be seen from the outside. And the daily life of the front part of door 4 Display sections 32a to 32e of operation menus that are particularly frequently used and their operation sections 22a to 32e Only 22e will be located outside. As a result, the required operation keys are easy to use. It is very easy to operate, and the operation panel on the 1a side of the microwave oven body is The operation keys 12a to 12e, 13a to 13h, 14a to 14g, and 16 of the control section 3 must be operated. Operation keys 13a to 13h, 14a to which must be operated directly by hand on the panel section 3 side Except for 14g and 16, they can be operated via the operating members 31, 31, etc. on the door 4 side. For items 12a to 12e, for example, a pin-shaped item with an extremely small diameter is sufficient. Therefore, if such a configuration is adopted, the amount of space required on the operation panel section 3 side will eventually be reduced. This creates more space for the operation keys, and as microwave ovens become more multi-functional, It becomes possible to sufficiently cope with an increase in the number of operation keys to a certain extent.

[0011] Moreover, with this configuration, unlike what was previously considered in some cases, there is a direct control on the door 4 side. Since the key itself is not installed, there is no need for electrical wiring, which was a problem. do not have.

0012

[Effect of the idea]

As a result of the above, the operation part structure of the microwave oven of the present invention is very easy to operate. Moreover, the structure of the operation panel can be easily designed to accommodate an increase in the number of operation menus at low cost. be able to provide it to

[0015] On the other hand, the reference numeral 4 indicates the side opposite to the operation panel section 3 of the microwave oven main body 1a (not shown). It is pivoted to the end of the left side via a pair of hinge mechanisms 6a, 6a so that it can be opened and closed horizontally. It's a microwave door. The door 4 is located at the side of the microwave oven main body 1a. Inside the door frame part 4a that covers the opening surface of the heat chamber 2 and the entire operation panel part 3. A finder section 4b located corresponding to the opening surface of the heating chamber 2 and the finder section 4b and a shield glass 4c fitted therein. And the above door af In front of the part 19 of the frame part 4a corresponding to the operation panel part 3 on the side of the microwave oven main body 1a. On the side, for example, as shown in Figure 2, there is a frequently used operation menu mentioned above. - Operation units 22a to 22e for pressing the corresponding keys corresponding to the keys 12a to 12e and the corresponding operations The same operation menu display area as menu keys 12a to 12e (operation menu display label) ) 32a to 32e are provided respectively.

[0016] The operation parts 22a to 22e are mounted on the door frame part 4a, as shown in FIG. 3, for example. A through hole 30 having a predetermined diameter is formed to penetrate from the front side to the back side, and inside the through hole 30, for example, For example, a pressing operation member 31 made of a rubber member is fitted and locked.

[0017] That is, the pressing operation member 31 is pressed against the door frame portion of the door 4 as shown in the figure. A pressing part 37 having a rounded surface slightly protruding from the front side of 4a, and A cylindrical stroke part 34 extending a predetermined length on the back side of the door frame part 4a. , extends from the periphery of the pressing portion 37 to the back side of the door frame portion 4a in a sleeve shape. A thin guide wall 38 that can be deformed and a door frame at the extending end of the guide wall 38. It is formed from a locking edge 39 to a part of the arm 4a. Also, the above stroke part A core material 33 is housed inside the core 34 to ensure rigidity during pressing operations.

[0018] The pressing operation member 31 is connected to the back side of the pressing portion 37 and the back side door frame. The coil spring 35 interposed between the part 36 of the part 4a keeps the door frame The portion 4a is biased so as to slightly protrude toward the front side. And the pressing part 37 When is pressed in the direction of the arrow shown in the figure, the stroke portion 34 moves toward the microwave oven main body side. The corresponding operation keys 12a to 12e protruding toward the operation panel section 3 are turned on. Applicable The pressing operation member 31 is provided in all of the above-mentioned operation sections 22a to 22e.
