[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2001-263673 Summary of the Invention [Problem to be solved by the invention]

[0004] In Patent Document 1, a liquid crystal display element and an electric circuit board are supported on a mounting base. The mounting base is attached to a control plate. When the liquid crystal display element is attached to a display window, there is a positional error between the liquid crystal display element and the display window, and an assembly error of the liquid crystal display element to the mounting base. In other words, when designing a liquid crystal display element, it is necessary to set dimensions that take into account a margin for the positional error and the assembly error. Therefore, in order to place the liquid crystal display element at a display window position predetermined by design, it is necessary to use a liquid crystal display element that is larger than the display window by the margin.

[0005] In view of the above-mentioned problems, an object of the present invention is to provide a cooking machine that can reduce the size of a display unit. [Means for solving the problem]

[0006] The cooking device according to the present invention includes a plate portion, a display unit, and a position determining portion. The plate portion has a transparent portion. The display unit has a display portion. The position determining portion is fixed to the plate portion and determines the position of the display unit by positioning the display portion relative to the transparent portion. [Effects of the Invention]

DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding parts are designated by the same reference numerals, and redundant description will not be repeated.

[0010] The cooking machine 1 will be described with reference to Fig. 1 and Fig. 2. Fig. 1 is an external perspective view showing the cooking machine 1 according to this embodiment. Specifically, it shows the appearance of the cooking machine 1 as seen from above, diagonally front right. Fig. 2 is a front view showing the cooking machine 1 according to this embodiment. The cooking machine 1 is, for example, a built-in type in which a part of the cooking machine 1 is embedded in a part of a wall. As shown in Figs. 1 and 2, the cooking machine 1 according to this embodiment includes a first cooking machine 2, a second cooking machine 4, a display device 6, and a control device 8.

[0011] In this embodiment, the side of the cooking appliance 1 on which the display device 6 is arranged is defined as the front X1, and the opposite side is defined as the rear X2. Furthermore, the left side of the cooking appliance 1 when viewed from the front X1 is defined as the left side Y1, and the opposite side is defined as the right side Y2. Furthermore, in the up-down direction Z, which is perpendicular to the front-rear direction X and the left-right direction Y of the cooking appliance 1, the side on which the display device 6 is arranged is defined as the upper side Z1, and the opposite side is defined as the lower side Z2.

[0012] The first cooking unit 2 is, for example, a microwave oven. In this embodiment, the first cooking unit 2 has, for example, a microwave heating mode and a grill heating mode as cooking modes. The microwave heating mode is a mode in which an object to be heated is cooked by mainly radiating microwaves into a cooking chamber. The grill heating mode is a mode in which an object to be heated is cooked by mainly using radiant heating.

[0013] The second cooking unit 4 is, for example, an oven range. The second cooking unit 4 is disposed above the first cooking unit 2 at Z1.

[0014] The single display device 6 is, for example, an LCD (Liquid Crystal Display). The display device 6 is a display device shared by the first cooking device 2 and the second cooking device 4.

[0015] The control device 8 controls the display on the display device 6 .

[0016] Specifically, the control device 8 includes a processor such as a CPU (Central Processing Unit). The processor controls the operation of the cooking appliance 1 and the single display device 6 by executing a computer program stored in a storage device (not shown). Specifically, the control device 8 can be realized by an ASIC (Application Specific Integrated Circuit) or the like.

[0017] The display device 6 is disposed above the second cooker 4 at a position Z1, and is capable of receiving both a first operation for the first cooker 2 and a second operation for the second cooker 4. The display device 6 displays a selection screen, an operation screen, and an indicator.

[0018] The first operation is a selection instruction operation for selecting the first cooking device 2, an instruction to select a cooking method for the first cooking device 2, or an instruction to select a cooking menu.

[0019] The second operation is a selection instruction operation for selecting the second cooking device 4, an instruction to select a cooking method for the second cooking device 4, or an instruction to select a cooking menu.

[0020] According to the heating cooking machine 1 of the present invention, even if the first cooking machine 2 and the second cooking machine 4 are arranged along the vertical direction Z, the first cooking machine 2 and the second cooking machine 4 can be easily operated using a single display device 6.

[0021] The display device 6 will be described in detail with reference to Figs. 3 to 5. Fig. 3 is a rear perspective view showing the display device 6 according to this embodiment. Specifically, Fig. 3 shows the appearance of the display device 6 as seen from above and diagonally rear right. Fig. 4 is an exploded perspective view showing the display device 6 according to this embodiment. Fig. 5 is a front view showing the plate portion 10 according to this embodiment. For ease of explanation, the directions in Figs. 5 to 9 are set based on the state in which the display device 6 is assembled to the cooking appliance 1.

[0022] As shown in FIGS. 3 and 4, the display device 6 includes a plate portion 10, a display unit 20, and a position determining portion 30. The plate portion 10 is a plate-like member.

[0023] The plate portion 10 transmits an image. The plate portion 10 is configured in a rectangular plate shape and covers the front X1 of the display unit 20. As shown in FIGS. 4 and 5, the plate portion 10 has a transparent portion 11, a first colored portion 12, and a second colored portion 14. The plate portion 10 is configured using, for example, glass as a material, but is not limited to this. The plate portion 10 only needs to be able to transmit at least an image, and may be configured using a synthetic resin material.

[0024] The transparent portion 11 is a colorless and transparent region. The transparent portion 11 transmits an image displayed by the display unit 20. The transparent portion 11 is configured in a rectangular shape. The transparent portion 11 is disposed in a middle region of the plate portion 10 in the left-right direction Y and the up-down direction Z.

[0025] The first colored portion 12 is a colored region. The first colored portion 12 is the entire back surface of the plate portion 10 excluding the transparent portion 11. In other words, the first colored portion 12 indicates the position of the transparent portion 11. The first colored portion 12 is colored, for example, by printing. The first colored portion 12 is, for example, black, but is not limited to this. The first colored portion 12 may be a dark color other than black. Furthermore, the coloring of the colored portion is not limited to printing. The coloring of the colored portion may also be colored by painting.

[0026] The second colored portion 14 is a colored region. The region 13 indicates a predetermined position. This predetermined position is where the position defining portion 30 is disposed. The region 13 is configured in a rectangular shape. The regions 13 are disposed at positions spaced apart from the transparent portion 11 in the left-right direction Y, corresponding to the position defining portions 30. Specifically, the left region 13 is spaced a predetermined distance from the left end of the transparent portion 11, and the right region 13 is spaced a predetermined distance from the right end of the transparent portion 11. The second colored portion 14 is colored on the back surface of the first colored portion 12, for example, by printing. In this embodiment, the second colored portion 14 is printed on the first colored portion 12 in the peripheral region of the transparent portion 11, excluding the region 13. That is, in the region 13, the first colored portion 12 is visible between the second colored portions 14. This makes the boundary of the region 13 clear, thereby improving visual recognition of the region 13. Furthermore, for example, if the first colored portion 12 and the second colored portion 14 are differentiated in brightness, the visibility can be further improved.

[0027] The display unit 20 displays an image. The display unit 20 is configured in a rectangular plate shape and is disposed behind the plate portion 10 at X2. Specifically, the display unit 20 is disposed behind the transparent portion 11 at X2. As shown in FIG. 4 , the display unit 20 includes a display portion 21, a support portion 22, and a substrate 23.

[0028] The display unit 21 displays an image. The display unit 21 is located behind the transparent unit 11 at X2. Specifically, the display unit 21 is configured in a rectangular shape that is larger outward than the transparent unit 11 when viewed from the front. In the display unit 21, for example, a plurality of pixels are arranged in a matrix. Each pixel is driven by active matrix driving. In active matrix driving, several TFTs (Thin Film Transistors) serve as switching elements for each pixel. The display unit 21 has a transparent insulating first substrate, a transparent insulating second substrate facing the first substrate, and a liquid crystal layer interposed between the first substrate and the second substrate (all not shown).

[0029] The support section 22 supports the display section 21 and the substrate 23. As shown in Fig. 4, the support section 22 has a support main body section 221 and an overhang section 222. The support main body section 221 and the overhang section 222 are configured as a single member made of, for example, synthetic resin.

[0030] The support main body part 221 supports the display unit 21 in the front X1. The support main body part 221 also supports the substrate 23 in the rear X2. The support main body part 221 is larger than the display unit 21 and is configured in a rectangular shape when viewed from the front. Note that the support main body part 221 is not limited to being larger than the display unit 21 and having a rectangular shape. The support main body part 221 may also be smaller than the display unit 21.

[0031] The protruding portions 222 hold the support main body portion 221 on the position determining portion 30. The protruding portions 222 are provided, for example, on both the left and right sides of the support main body portion 221. When the display unit 20 is placed in a set location on the board portion 10, the pair of left and right protruding portions 222 are respectively located behind the pair of left and right regions 13 at X2.

[0032] The substrate 23 controls the display of the display unit 21. As shown in FIG. 4, the substrate 23 has a control substrate, a driver substrate (neither of which are shown), and signal lines 24. The control substrate controls the display unit 21. The driver substrate drives the display unit 21. The signal lines 24 connect the control substrate and the driver substrate.

[0033] The position determining portion 30 determines the position of the display unit 20. The position determining portion 30 is fixed to the plate portion 10. The position determining portion 30 positions the display portion 21 relative to the transparent portion 11. As a result, the display device 6 allows the display portion 21 to be made smaller. That is, the display portion 21 is fixed to the plate portion 10 via the position determining portion 30. A display portion that is not fixed to the plate portion is subject to positional deviation errors and assembly errors. Therefore, the display portion 21 that is fixed to the plate portion 10 via the position determining portion 30 can reduce the amount of positional deviation relative to the transparent portion 11 compared to a display portion that is not fixed to the plate portion 10. Therefore, the margin that takes the amount of positional deviation into consideration can be reduced, and the size of the display portion 21 can be made smaller compared to a display portion that is not fixed to the plate portion 10.

[0034] As shown in FIGS. 4 and 5, the first colored portion 12 indicates the position of the display unit 21. The second colored portion 14 indicates the position of the position determining portion 30. This allows the display device 6 to further reduce the size of the display unit 21. Because the mounting position of the position determining portion 30 is clear, the accuracy of the work when mounting the position determining portion 30 is improved. As a result, the mounting accuracy of the display unit 20 to the plate portion 10 can be improved, and the margin of the display unit 21 can be reduced.

[0035] The display device 6 will be described in further detail with reference to Figs. 6 to 10. Fig. 6 is a perspective view showing the position determining section 30 according to this embodiment. Fig. 7 is a view showing a state in which the position determining section 30 is arranged on the plate section 10. Fig. 8 is a view showing a state in which the base 40 is arranged on the plate section 10. Fig. 9 is a view showing a state in which the display unit 20 is arranged on the position determining section 30. Fig. 10 is a cross-sectional view taken along line XX in Fig. 9.

[0036] As shown in FIGS. 6 to 8, the position determining portion 30 has a main body portion 31, a protruding portion 32, a protruding portion 33, a boss portion , and a pin portion .

[0037] The main body 31 is made of a synthetic resin material and has a rectangular parallelepiped shape. The main body 31 has an upper portion 311, a lower portion 312, an inner portion 313, an outer portion 314, and a front portion 315. The inner portion 313 is the side portion closer to the transparent portion 11, and the outer portion 314 is the side portion farther from the transparent portion 11. The main body 31 corresponds to, for example, a "position-defining main body."

[0038] The front portion 315 has substantially the same shape as the region 13 in a front view. The front portion 315 overlaps the region 13. As shown in FIG. 6, for example, double-sided tape 36 is attached to the front surface of the front portion 315. As shown in FIGS. 7 and 8, the front portion 315 is attached to the back surface (rear surface) of the plate portion 10 via the double-sided tape 36 so as to overlap the region 13. Protrusions 32 are partially provided on both left and right ends of the front portion 315. The protrusions 32 protrude rearward X2 from the rear surface of the front portion 315 at a middle portion in the up-down direction Z.

[0039] As shown in Fig. 8, the inner portion 313 and the outer portion 314 are provided with protrusions 33. Specifically, the inner protrusion 331 extends toward the rear X2 at a middle portion of the inner portion 313 in the up-down direction Z. The outer protrusion 332 extends toward the rear X2 at a middle portion of the outer portion 314. In other words, the protrusions 33 protrude in the opposite direction from the plate portion 10. The pair of protrusions 33 are spaced apart by a predetermined distance in the left-right direction Y.

[0040] For example, a pair of pin portions 35 are provided, one above the other, between the inner portion 313 and the outer portion 314, with the protrusion 33 therebetween. The pair of pin portions 35 extend from the front portion 315 toward the rear X2. The rear X2 ends of the pin portions 35 are located further rearward X2 than the rear X2 end of the boss portion 34. The rear ends of the pin portions 35 are tapered.

[0041] For example, a pair of boss portions 34 are provided above and below between the inner portion 313 and the outer portion 314, with the protrusion 33 and the pin portion 35 interposed therebetween. The pair of boss portions 34 extend from the front portion 315 toward the rear X2.

[0042] 9, the protruding portion 222 protrudes outward from the support main body portion 221 beyond the display portion 21 (see FIG. 4). The display unit 20 is held by the position determining portion 30 via the protruding portion 222. This allows the display unit 20 to be held by the position determining portion 30 with a simple configuration.

[0043] As shown in FIGS. 4 and 9, the protruding portion 222 has a protruding hole 223, a boss hole 224, and a pin hole 225.

[0044] As shown in FIG. 9, the inner protrusion 331 (see FIG. 8) is inserted into the protrusion hole 223. The outer protrusion 332 (see FIG. 8) is located outward from the outer end of the overhanging portion 222. A portion of the overhanging portion 222 is sandwiched between the inner protrusion 331 and the outer protrusion 332. The display unit 20 is supported in a position where the protrusion 331 is inserted into the protrusion hole 223. This improves positioning accuracy. Specifically, because the protrusion 331 is inserted into the protrusion hole 223, it is possible to prevent the display unit 20 from shifting in the vertical direction Z and the horizontal direction Y.

[0045] A pair of pin holes 225 are provided above and below via the protruding hole 223. A pair of pin portions 35 (see FIG. 4) are inserted into the pair of pin holes 225, respectively. The diameter of the pin holes 225 is approximately the same as the diameter of the pin portions 35. Therefore, when the pin portions 35 pass through the pin holes 225, the display unit 20 is positioned relative to the position determining portion 30. Note that, because the rear ends of the pin portions 35 are tapered, when the pin portions 35 are inserted, the pin portions 35 are guided by the tapered shape toward the pin hole 225 and finally enter the pin hole 225.

[0046] A pair of boss holes 224 are provided above and below via the protruding hole 223 and the pin hole 225. When the pin portion 35 is inserted into the pin hole 225, the boss portion 34 is positioned in front X1 of the boss hole 224. Therefore, the pair of boss portions 34 face each other in the front-rear direction X in the pair of boss holes 224.

[0047] As shown in FIGS. 3 and 4, the display device 6 has a base 40.

[0048] The base 40 sandwiches the position determining unit 30 between itself and the plate portion 10. The base 40 fixes the position determining unit 30. That is, the base 40 fixes the position determining unit 30 to the plate portion 10 in a position where the position determining unit 30 is sandwiched between itself and the plate portion 10. This makes it possible to prevent the display unit 21 from shifting position relative to the transparent portion 11. Specifically, attaching the base 40 to the plate portion 10 also serves to fix the position determining unit 30 to the plate portion 10. The base 40 attaches the display unit 20 and the like to the second cooking device 4. The base 40 sandwiches the position determining unit 30 between itself and the plate portion 10. The base 40 has a first opening 41, a second opening 42, a pressing portion 43, an assembly bracket 44, and an attachment bracket 45.

[0049] 4 and 8, when the pair of position determining units 30 are attached to the plate unit 10, the first opening 41 is formed from the inner portion 313 (see FIG. 6) of one position determining unit 30 to the inner portion 313 of the other position determining unit 30. Specifically, the first opening 41 is provided so as to substantially correspond to the display unit 21.

[0050] As shown in Fig. 4, a pair of second openings 42 are provided on the left and right sides. When the pair of position determining parts 30 are attached to the plate part 10, the pair of position determining parts 30 are inserted into the pair of second openings 42, respectively. A pair of mounting brackets 15 are attached to both the left and right sides of the plate part 10, respectively. The mounting brackets 15 are provided with screw holes for fastening with screws (not shown).

[0051] As shown in Fig. 10, the pressing portions 43 are disposed on the left and right sides of the position determining portion 30. Specifically, the pressing portions 43 are in contact with the rear surfaces of the protrusions 32. As shown in Fig. 8, after the base 40 is placed on the rear surface of the plate portion 10, the assembly bracket 15 and the assembly bracket 44 are fastened together with screws. This brings the plate portion 10 and the base 40 into close contact, and the pressing portions 43 press the protrusions 32 toward the plate portion 10.

[0052] The display device 6 is configured by assembling a position determining part 30 and a base 40 to a plate part 10, and assembling a display unit 20 to the position determining part 30. The display device 6 is attached to the housing of the cooking appliance 1 via an attachment bracket 45.
