The embodiments described below are not intended to limit the scope of the present invention as described in the claims. Furthermore, not all of the configurations described below are essential requirements of the present invention.

[0010] Figures 1 to 8 show one embodiment in which the heating appliance 1 is applied to a microwave oven. First, the overall configuration of the heating appliance 1 will be explained. The heating appliance 1 of the present invention has a cooking function by oven heating, which heats the food to be cooked S with hot air supplied into the cooking chamber 15 or heats the food to be cooked S contained in a container C; a cooking function by grill heating, which heats the food to be cooked S with the heat of a heater or heats the food to be cooked S contained in a container C; and a cooking function by microwave heating, which heats the food to be cooked S by irradiating the food to be cooked S with microwaves or irradiating the food to be cooked S contained in a container C. It has a main body 2 which is configured in the shape of a roughly rectangular box and a door 3 which is provided to cover almost the entire front of the main body 2. The main body 2 also has a metal cabinet 4 as a member that covers the outer casing of the heating appliance 1 which will be the product.

[0011] Door 3 is rotatably connected to the main body 2 at its lower end and is designed to open and close vertically. When door 3 is closed, the front opening of the cooking chamber 15 is covered, creating a closed space within the cooking chamber 15. Door 3 also has a main body door 3-1 and a handle 3-2 on the top of the door body 3-1 for opening and closing the vertically opening door 3. A window 5 is provided approximately in the center of the door body 3-1, through which the inside of the cooking chamber 15 can be seen. An operation panel 6 for display, notification, and operation is provided on the right side of the door body 3-1. The operation panel 6 is equipped with a display means 7 for displaying cooking settings and progress, and an operation means 8 for enabling various operation inputs related to heating and cooking. The operation means 8 consists of a cooking start instruction means 8a, a cancellation instruction means 8b, and an electrostatic touch panel 8c provided on the surface of the display means 7. Therefore, the operation means 8 functions as a selection means for selecting heating conditions.

[0012] The display means 7 is a backlit display that displays all information related to cooking, such as the type of heating, the name of the dish, the heating time, the temperature, and a photograph of the cooking process, in color using characters, numbers, symbols, and photographs. In this case, it is composed of a liquid crystal display using TFT (thin film transistor) as a switching element, but other display devices such as organic EL may be used, and it is not limited to color display but can also be monochrome display.

[0013] The cooking start instruction means 8a and the cancellation instruction means 8b in this embodiment are composed of hardware keys and are provided as push operation units that accept push operations from the user. The cooking start instruction means 8a is pressed when heating cooking is started, and the cancellation instruction means 8b is pressed when heating cooking is stopped midway, that is, when instructing the cancellation of heating cooking, or when canceling an operation or setting. The touch panel 8c is provided on the upper surface which is the surface of the display means 7, and enables the selection operation of one of the multiple display elements displayed on the display means 7 by touch operation with a fingertip.

[0014] Below the bottom wall 15a of the cooking chamber 15, a microwave heating means 25 is provided that supplies microwaves, which are radio waves, into the cooking chamber 15 and irradiates the food to be cooked S or the food to be cooked S contained in a container C with microwaves to perform microwave heating. The microwave heating means 25 is composed of a magnetron 26 that generates microwaves, an antenna 28 that receives the microwaves guided from the magnetron 26 to the cooking chamber 15 via a waveguide 27 and radiates the microwaves into the interior of the cooking chamber 15, and an antenna motor 29 such as an AC motor that rotates the antenna 28 horizontally around an upright axis.

[0015] A grill heater 23 is installed on the ceiling wall 15b of the cooking room 15. In this embodiment, the grill heater 23 is configured to perform grill heating by heating the food to be cooked S inside the cooking room 15, or the food to be cooked S contained in the container C, with radiant heat.

[0016] The back wall 15c of the cooking chamber 15 has an intake vent (not shown here) in the center for drawing air from the cooking chamber 15, and multiple supply holes 33 for supplying hot air into the cooking chamber 15 are provided above, below, to the left and right of the intake vent. Behind the back wall 15c is a hot air unit 34 equipped with a hot air heater 35 for heating the air, a hot air fan 36 for sending the air heated by the hot air heater 35 into the cooking chamber 15 and circulating it, and a hot air motor 37 for rotating the hot air fan 36 in a predetermined direction. In this invention, the hot air fan 36 is rotated and the air heated by the hot air heater 35 is supplied into the cooking chamber 15, thereby performing hot air convection heating (oven heating) on ​​the food to be cooked S in the cooking chamber 15, or on the food to be cooked S contained in the container C.

[0017] On the left and right side walls 15d and 15e of the cooking chamber 15, a pair of left and right shelf supports 22 are provided in two upper and lower stages to store and hold a metal square dish 21 in a suspended state inside the cooking chamber 15. In Fig. 2, it shows a state where the square dish 21 is placed on the lower shelf support 22 inside the cooking chamber 15 and a container C is placed on the square dish 21. However, depending on the cooking, the square dish 21 may be placed only on the upper shelf support 22, or two square dishes 21 may be placed on the upper and lower shelf supports 22 respectively. Instead of the square dish 21, other accessories such as a baking net (not shown) may be stored and held. Also, in the range heating by the microwave generating device 25 described above, the object to be cooked S can be heated and cooked by putting it in a container C capable of range heating inside the cooking chamber 15 without putting a square dish 21, a baking net, etc. inside the cooking chamber 15.

[0018] In addition, a temperature detection means 47 is incorporated above the left side wall 15d of the cooking chamber 15, and a food temperature detection means 48 is incorporated above the right side wall 15e of the cooking chamber 15. The temperature detection means 47 detects the temperature inside the cooking chamber 15 and is composed of, for example, a thermistor. The food temperature detection means 48 is configured by equipping an infrared sensor (not shown) with a swing mechanism, and by detecting the temperature distribution inside the cooking chamber 15, it can non-contact detect the temperature of the object to be cooked accommodated therein.

[0019] Fig. 4 shows (A) a partially enlarged cross-sectional perspective view seen from the front of the door 3, (B) a cross-sectional view of the door 3, and (C) a partially enlarged cross-sectional perspective view seen from the back of the door 3. Fig. 5 is an explanatory view showing the positional relationship among the glass member 57, the frame 51, the outer frame upper cover 52, the outer frame left cover 54, the inner storage heat-resistant glass 55, the substrate 61, and the substrate 62. Fig. 6 is an explanatory view showing the positional relationship among the glass member 57, the frame 51, the inner storage heat-resistant glass 55, the substrate 61, and the substrate 62. Referring to these figures for explanation, the door body 3-1 forms the side surface of the door 3, and includes the frame 51 to which each component is attached, the outer frame upper cover 52, the outer frame lower cover 53, the outer frame left cover 54, the inner storage heat-resistant glass 55, and the heat-resistant glass holding part 56 disposed at the rear of the frame 51, and the glass member 57 provided so as to cover the front part of the frame 51. Therefore, the frame 51, the outer frame upper cover 52, the outer frame lower cover 53, the outer frame left cover 54, the inner storage heat-resistant glass 55, and the heat-resistant glass holding part 56 act as an outer contour having the side surface part and the back surface part of the door 3, and the glass member 57 is provided so as to cover the front surfaces of these frame 51, the outer frame upper cover 52, the outer frame lower cover 53, the outer frame left cover 54, the inner storage heat-resistant glass 55, and the heat-resistant glass holding part 56.

[0020] The frame 51, the upper outer frame cover 52, the lower outer frame cover 53, and the left outer frame cover 54 are made of resin. A circuit board 61 on which the display means 7 is mounted and to which the touch panel 8c is connected, and a circuit board 62 on which the cooking start instruction means 8a and the cancellation instruction means 8b are mounted are disposed in the space 58 formed between the glass member 57 and the left outer frame cover 54. In this embodiment, the lower side of the left outer frame cover 54 is open, and the door body 3-1 is configured such that the space 58 communicates with the space 63 formed between the glass member 57 and the lower outer frame cover 53, allowing air from a cooling fan (not shown) disposed in the space 63 to pass through the space 58, particularly through the circuit boards 61 and 62. Furthermore, the outer frame upper cover 52 is provided with counterbore holes 59, 59.... Screws (not shown) are inserted into these counterbore holes 59, 59.... and these screws are screwed into the handle 3-2 through screw holes (not shown) in the frame 51 and through holes 57-4, 57-4... (described later). This configuration allows the handle 3-2 to sandwich the frame 51 and the glass member 57 between the handle 3-2 and the outer frame upper cover 52, attaching the handle 3-2 to the glass member 57, and positioning the handle 3-2 so as to cover the through holes 57-4, 57-4.... Therefore, the handle 3-2 can be directly and firmly attached to the glass member 57, and the through holes 57-4, 57-4... are hidden and not visible from the front of the cooking appliance 1, thus suppressing the lack of a sense of unity in the door 3 and giving the cooking appliance 1 a very smart appearance.

[0021] The glass member 57 is made of glass using a sodium compound and is a single flat rectangular plate, formed so that when viewed from above it has substantially the same shape as the outline of the frame 51. Referring to Figure 7, a light-transmitting area 57-1 for the window is provided in the approximate center of the glass member 57, and a light-transmitting area 57-2 for the display is provided to the right of the light-transmitting area 57-1 for the window. Below the light-transmitting area 57-2 for the display is a through-hole 57-3 for hardware keys, and multiple through-holes 57-4, 57-4... for screws to be inserted for attaching the handle 3-2 are provided in the upper part of the glass member 57. Printing P is applied to areas of the glass member 57 other than the light-transmitting area 57-1 for the window, the light-transmitting area 57-2 for the display, the through-holes 57-3, and the through-holes 57-4, 57-4... This configuration allows most of the front surface of the door 3 to be made of glass members 57, suppressing an increase in the number of parts of the door 3 and ensuring a unified design for the door 3, thus preventing a lack of a sense of unity. In this embodiment, the printing P is applied to the back surface of the glass member 57 on the cooking compartment 15 side of the door 3, but it may also be configured so that the printing P is applied to the front surface of the glass member 57 on the outer surface of the door 3. Furthermore, by applying the printing P to the glass member 57, it may be configured so that heat conduction is suppressed in the area where the printing P is applied.

[0022] The light-transmitting area 57-1 for the window section, together with the heat-resistant glass 55 on the inside of the oven cavity, constitutes the window section 5. In this embodiment, the window section 5 is provided on the door 3 so that when the door 3 is closed, the upper edge of the window section 5 is near the position of the ceiling wall 15b of the cooking room 15, and the lower edge of the window section 5 is near the position of the bottom wall 15a of the cooking room 15. The light-transmitting area 57-1 for the window section is also provided on the glass member 57 so that items inside the cooking room 15, especially those placed on the bottom wall 15a of the cooking room 15, can be viewed favorably through the window section 5. The window section 5 may also be equipped with an electromagnetic shielding structure by sandwiching perforated metal between the light-transmitting area 57-1 for the window section and the heat-resistant glass 55 on the inside of the oven cavity.

[0023] The light-transmitting area 57-2 for the display unit, together with the touch panel 8c, constitutes a touch key. The touch panel 8c is disposed on the back surface of the light-transmitting area 57-2 of the glass member 57, and the light-transmitting area 57-2 constitutes the part where the touch key is operated. The light-transmitting area 57-2 is formed in a vertically elongated shape, which is substantially the same shape as the screen of the display means 7, and is disposed on the surface of the display means 7 together with the touch panel 8c. Together with the display means 7, the light-transmitting area 57-2 and the touch panel 8c constitute a display operation means that accepts touch operations and displays various information. In this embodiment, since the glass member 57 is formed using a sodium compound, the light-transmitting area 57-2 can be suitably used as the part where the touch key is operated. Furthermore, by forming the light-transmitting area 57-2 for the display section in a vertical shape, the space to the sides of the large light-transmitting area 57-1 for the window section, which is provided vertically on the glass member 57, is effectively utilized to improve visibility. In addition, the display means 7 and touch panel 8c, which are means of display operation, can be positioned at the top of the glass member 57, i.e., towards the upper side of one side of the door 3, which is close to the user's line of sight. This configuration makes it easier for the user to operate the cooking start instruction means 8a, the cancellation instruction means 8b, and the touch panel 8c while checking the screen of the display means 7, thereby improving operability and visibility. Moreover, information on heating appliances often consists of few characters, such as dish names and ingredient names. For example, the instructions in recipes are often summarized in short, simple, and easy-to-understand bullet points, and many also use photographs and diagrams. Therefore, a vertically oriented screen for the display means 7 allows for more information to be displayed on a single screen. Consequently, by configuring the screen of the display operation means to be vertically oriented, more information can be provided, improving convenience.

[0024] The through-hole 57-3 is for exposing the cooking start instruction means 8a and the cancellation instruction means 8b, which are push-operated parts. To facilitate operation while checking the display means 7, the cooking start instruction means 8a and the cancellation instruction means 8b are located below the vicinity of the display means 7, and the through-hole 57-3 is drilled below the vicinity of the light-transmitting area 57-2 for the display unit. In this embodiment, by providing the through-hole 57-3 and exposing only the cooking start instruction means 8a and the cancellation instruction means 8b, the lack of a sense of unity in the door 3 is suppressed and the design is enhanced.

[0025] As shown in Figure 5, the through-hole 57-3 in this embodiment is formed along the front view contours of the push-button 64 operated by the cooking start instruction means 8a and the push-button 65 operated by the cancellation instruction means 8b. However, there is only one through-hole 57-3, and the cooking start instruction means 8a and the cancellation instruction means 8b are exposed from the front through this single through-hole 57-3. This suppresses a lack of unity in the door 3 and reduces the effort required to process the glass member 57. Also, as shown in Figure 4(B), the push-buttons 64 and 65 in this embodiment are configured so that the exposed front portions are flat, and the front portions of these push-buttons 64 and 65 are arranged to be substantially flush with the front surface of the glass member 57. By configuring it in this way, the heating appliance 1 of this embodiment can have a very smart appearance. In addition, the front surface of the door 3 can be made substantially flat, improving cleanability by making it easier to wipe clean.

[0026] Furthermore, the cooking start instruction means 8a and the cancellation instruction means 8b are configured such that the distance they travel during the pressing operation is shorter than the thickness of the glass member 57. This prevents the pressing parts 64 and 65 from interfering with the back surface of the glass member 57 during the pressing operation, ensuring that the cooking start instruction means 8a and the cancellation instruction means 8b operate reliably.

[0027] In this embodiment, an inclined portion is formed on the lower edge 66 of the push-button 64, which is the side facing the push-button 65, and an inclined portion is formed on the upper edge 67 of the push-button 65, which is the side facing the push-button 64. By creating a step between the push-button 65 and the push-button 64, the accidental pressing of the cooking start instruction means 8a and the cancellation instruction means 8b is suppressed. Note that this configuration is just one example, and the step may also be created by forming a forward-projecting convex portion on the lower edge 66 of the push-button 64 and the upper edge 67 of the push-button 65. Furthermore, in this embodiment, the cooking start instruction means 8a and the cancellation instruction means 8b are configured such that, as shown in Figure 8(A), the upper edge of the push portion 64 and the lower edge of the push portion 65 corresponding to the four corners of the through hole 57-3 have rounded edges with a small radius at both ends. However, as shown in Figure 8(B), the upper edge of the push portion 64 and the lower edge of the push portion 65 may be configured such that the upper edge of the push portion 64 and the lower edge of the push portion 65 have rounded edges with a large radius at both ends. Alternatively, as shown in Figure 8(B), the lower edge of the push portion 65 may be configured such that the upper edge of the push portion 64 is arc-shaped or dome-shaped.

[0028] As described above, the heating cooker 1 of this embodiment comprises a main body 2 having a cooking chamber 15 inside, and a door 3 covering the opening of the cooking chamber 15. The door 3 has a frame 51 as an outer shell having side and back parts of the door 3, an upper outer frame cover 52, a lower outer frame cover 53, a left outer frame cover 54, an inner heat-resistant glass 55 and a heat-resistant glass holding part 56, a single plate-shaped glass member 57 provided to cover the front of these outer shell parts 51 to 56, and a display means 7, a light-transmitting area 57-2 for the display unit and a touch panel 8c as a display operation means that accepts touch operations and displays various information, and the glass member 57 is configured to have a light-transmitting area 57-2 for the display unit as the part where the touch operation means is performed.

[0029] By configuring it in this way, most of the space on the front of the door 3 can be made of glass material 57, which helps to reduce the number of parts in the door 3. In addition, it allows for a consistent design in the door 3, thus preventing a lack of unity in the door 3.

[0030] Furthermore, the glass member 57 of this embodiment has a through hole 57-3 formed therein, and the cooking start instruction means 8a and the cancellation instruction means 8b, which serve as operable hardware keys, are exposed through the through hole 57-3, thereby suppressing a lack of unity in the door 3.

[0031] Furthermore, the cooking start instruction means 8a and the cancellation instruction means 8b in this embodiment are multiple hardware keys, and the cooking start instruction means 8a and the cancellation instruction means 8b, which are multiple hardware keys, are exposed from a single through-hole 57-3. This configuration helps to suppress the lack of a sense of unity in the door 3 and reduces the effort required to process the glass member 57.

[0032] Furthermore, the cooking start instruction means 8a and the cancellation instruction means 8b of this embodiment are configured such that the push parts 64 and 65, which serve as the front surface, are arranged to be substantially flush with the front surface of the glass member 57, allowing the cooking appliance 1 to have a very sleek appearance. In addition, the front surface of the door 3 can be configured to be substantially flat, improving ease of cleaning.

[0033] Furthermore, in the cooking appliance 1 of this embodiment, the door 3 has a handle 3-2 that is gripped when opening and closing, and the glass member 57 has through holes 57-4, 57-4... which serve as holes for attaching the handle 3-2 to the door 3, and the handle 3-2 is positioned to cover the front side of the through holes 57-4, 57-4.... Therefore, the handle 3-2 can be directly and firmly attached to the glass member 57, and the through holes 57-4, 57-4... are hidden and not visible from the front of the cooking appliance 1, thus suppressing the lack of a sense of unity in the door 3 and making the cooking appliance 1 have a very smart appearance.

[0034] Furthermore, in the heating appliance 1 of this embodiment, the light-transmitting area 57-2 for the display section is formed in a vertically elongated shape, and the space to the sides of the large light-transmitting area 57-1 for the window section, which is provided vertically in the glass member 57, can be effectively utilized to improve visibility. In addition, the display operation means can be placed at the top of the door 3, which is close to the user's line of sight, thus improving operability and visibility.

[0035] It should be noted that the present invention is not limited to the above embodiments, and various modifications are possible without departing from the spirit of the invention. For example, in addition to the cooking start instruction means 8a and the cancellation instruction means 8b, hardware keys such as a dial key may be mounted on the circuit board 62, and these hardware keys may be exposed together with the cooking start instruction means 8a and the cancellation instruction means 8b through the through hole 57-3. In this embodiment, the touch key is composed of the touch panel 8c and the light-transmitting area 57-2 for the display unit, but the touch panel 8c may be configured to accept touch operations performed on the light-transmitting area 57-2 for the display unit. For example, the touch panel 8c may be configured such that a touch key already attached to a touch operation plate such as an acrylic plate is placed on the back surface of the light-transmitting area 57-2 for the display unit, and the touch panel 8c accepts touch operations via the light-transmitting area 57-2 for the display unit and the touch operation plate. Bosses for mounting screws may be formed on the handle 3-2, and the through holes 57-4, 57-4... may be formed so that these bosses can be inserted through them. Furthermore, the configuration and shape of each part of this embodiment are not limited to those shown in the illustration and can be modified as appropriate. [Explanation of Symbols]
