[0009] (Findings that form the basis of the present invention) The present inventors have conducted extensive research into how to efficiently recover water from the heating chamber, and have come to the following findings.

[0010] In conventional cooking appliances, a water receiving section is provided below the joint between the front frame around the opening and the rear side of the door, and a tray is placed below this water receiving section. The water receiving section is fixed to the bottom surface of the front frame, which extends rearward from the lower edge of the front frame.

[0011] However, in conventional cooking appliances, the heating chamber and front frame are constructed by laminating multiple steel plates together, which creates gaps at the front corners of the heating chamber corresponding to the corners of the steel plates. This causes water to leak from these gaps, and the gaps at the front corners of the heating chamber are sealed from the back with silicone putty. The inventors discovered that instead of sealing the gaps at the front corners of the heating chamber, they can efficiently collect water generated inside the heating chamber through these gaps. This reduces the amount of water that drips down between the door and the front frame, thereby reducing the amount of water that adheres to the front frame when the user opens the door and reducing the effort required for the user to wipe and clean the front frame.

[0012] Based on these novel findings, the present inventors have arrived at the following invention.

[0013] According to a first aspect of the present invention, there is provided a heating device including: a main body having a heating chamber and a front frame provided around an opening of the heating chamber; a door that covers the opening in an openable and closable manner and is attached to the main body; a water receiving plate disposed below the heating chamber and on the rear surface of the front frame, for receiving water that flows down from the front corners of the heating chamber; The cooking device provides a cooking device in which the water receiving plate has drainage holes for draining water from the front surface side to the back surface side of the water receiving plate, and a guide portion for guiding water to the drainage holes.

[0014] This configuration allows for efficient collection of water generated within the heating chamber. Furthermore, it is possible to reduce the amount of water that drips down between the door and the front frame, which reduces the amount of water that adheres to the front frame when the user opens the door, reducing the effort required for the user to wipe and clean the front frame.

[0015] According to a second aspect of the present invention, there is provided the cooking device according to the first aspect, wherein the guide portion is made of a rubber member having a waterproof function.

[0016] With this configuration, the guide portion seals the gap between the front frame and the water receiving plate, preventing water flowing down from the front corners of the heating chamber from leaking out between the front frame and the water receiving plate, and directing water flowing down from the front corners of the heating chamber from the top surface of the guide portion to the drain hole.

[0017] According to a third aspect of the present invention, there is provided the cooking device according to the first or second aspect, wherein the guide portion is inclined downward from the end of the water receiving plate toward the drainage hole.

[0018] With this configuration, the downward inclination from the upper surface of the end of the guide portion allows water flowing down from the front corner of the heating chamber to be guided to the drain hole below.

[0019] According to a fourth aspect of the present invention, the water receiving plate is located below the drain hole and The cooking device according to any one of the first to third aspects has a water receiving portion on the back side of the plate.

[0020] With this configuration, water that flows from the surface of the water receiving plate through the drainage holes and out onto the back side of the water receiving plate can be temporarily received by the water receiving section and then guided to another location.

[0021] According to a fifth aspect of the present invention, a bottom plate for receiving water that flows down from the water receiving portion is provided, In a fourth aspect of the present invention, there is provided the cooking device, wherein the water receiving portion is configured by cutting and raising the water receiving plate toward the rear surface side, and the bottom plate has a drainage hole.

[0022] With this configuration, water that flows from the surface of the water receiving plate through the drainage holes to the back side of the water receiving plate is temporarily received by the water receiving section, and the water can be guided from the water receiving section to the bottom plate. Furthermore, the bottom plate has drainage holes, so the water can be guided further from the drainage holes to another location. Furthermore, because the water receiving section is cut out and raised from the water receiving plate toward the back side, it is configured as part of the water receiving plate, eliminating the need to attach the water receiving section to the water receiving plate as a separate part, thereby reducing manufacturing costs.

[0023] According to a sixth aspect of the present invention, there is provided the cooking device according to the fifth aspect, wherein the bottom plate has a recess formed in a position to receive water that flows down from a tip of the water receiving portion, and the recess has a drainage hole.

[0024] With this configuration, water can be temporarily stored in the recess in the bottom plate, and the water can be guided to another location through the drainage holes formed in the recess.

[0025] According to a seventh aspect of the present invention, there is provided the cooking device according to the fifth or sixth aspect, further comprising a water receiving tray below the bottom plate for receiving water that drips down through the water drainage holes.

[0026] With this configuration, the water that flows down through the drain holes in the bottom plate can be finally collected in the water receiving tray. If this water receiving tray is configured to be detachable from the main body, the user can remove the water receiving tray from the main body and discard the water, thereby facilitating maintenance of the water receiving tray.

[0027] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In the following drawings, the X direction is the width direction of the cooking device 1, the Y direction is the front-rear direction, and the Z direction is the height direction. However, the present invention is not limited to this embodiment.

[0028] (Embodiment 1) Fig. 1 is a front perspective view of a cooking appliance 1 according to embodiment 1. Fig. 2 is a front perspective view of the cooking appliance 1 with a door 9 open.

[0029] As shown in FIGS. 1 and 2, the cooking device 1 includes a main body 3, a water tray 7 for collecting water generated inside the main body 3, and a door 9 attached to the main body 3 so as to be openable and closable.

[0030] The main body 3 has a heating chamber 31 that heats the object to be heated inside the main body 3, and a front frame 33 that is provided on the front side of the main body 3. The space to the right of the heating chamber 31 is used as a machine room (not shown). This machine room contains a drive mechanism that drives each function of the cooking device 1, a magnetron that generates microwaves, a magnetron drive power supply that supplies power to the magnetron, a control unit that controls the microwave generation operation, etc. A radiation antenna for radiating microwaves is provided below the heating chamber 31. The microwaves radiated from the radiation antenna are configured to dielectrically heat the object to be heated placed in the heating chamber 31. A steam generating unit is installed on the side of heating chamber 31, and a steam outlet is provided on the side of heating chamber 31, allowing steam to be supplied into heating chamber 31. An opening 31a is provided on the front surface of heating chamber 31 for putting in and taking out an object to be heated. A front frame 33 is provided around opening 31a of heating chamber 31.

[0031] The water receiving tray 7 may be located below the front frame 33 (in the -Z direction) and detachably attached to the main body 3. It ultimately collects water that flows down between the front frame 33 and the door 9, as well as water that flows down through the front corner holes 33a, which will be described later.

[0032] The door 9 covers the opening 31a of the heating chamber 31 in an openable and closable manner. The door 9 is attached to the main body 3 below the opening 31a so that the door 9 serves as a horizontal rotation center, and is configured to be openable and closable in the vertical direction. The door 9 opens when a user pulls a handle 91 attached to the top of the door 9. The heating chamber 31 is closed by rotating the door 9 to a vertical position, and is opened by rotating the door 9 to a horizontal position. An operation display panel 90 is also arranged on one side of the main body 3 when viewed from the front, and a display unit 93 and an operation unit 95 are arranged on the operation display panel 90. The display unit 93 is, for example, an LCD screen that displays a menu screen and the like. The operation unit 95 includes push buttons and a dial. The user is configured to be able to issue various cooking instructions to the cooking appliance 1 using the operation unit 95.

[0033] In addition, grill plates and iron plates can be installed at multiple heights inside the heating chamber 31, so that the food to be heated can be placed on the grill plate or iron plate and cooked according to the cooking method of the food to be heated, or the food can be placed on the platform 31d at the bottom of the heating chamber 31 and cooked.

[0034] Fig. 3 is a front view of the cooking appliance 1 with the door 9 and the operation display panel 90 removed. Fig. 4 is a partial front perspective view of the cooking appliance with at least the door removed, and an enlarged view thereof.

[0035] 3 and 4, the cooking device 1 includes a heating chamber 31 having a heating chamber side surface 31b, a heating chamber bottom surface 31c, and a heating chamber top surface. The heating chamber side surface 31b and the heating chamber bottom surface 31c are each made of a steel plate such as a galvanized steel plate. A mounting table 31d is formed on the heating chamber bottom surface 31c, and an object to be heated placed on the mounting table 31d can be heated.

[0036] In addition, the front frame 33 provided around the opening 31a of the heating chamber 31 is composed of a front frame lower part 33b, a front frame side part 33c, and a front frame upper part in Figure 4, and the front frame lower part 33b and the front frame side part 33c are composed of a single steel plate.

[0037] Front corner holes 33a are provided at the front corners where the front frame lower portion 33b, front frame side portions 33c, heating chamber side surfaces 31b, and heating chamber bottom surface 31c intersect. Front corner holes 33a are formed by corresponding to the positions of the joints between the steel plates comprising the front frame lower portion 33b and front frame side portions 33c, the steel plates of the heating chamber side surfaces 31b, and the steel plates of the heating chamber bottom surface 31c.

[0038] When cooking an object to be heated (food, beverage, etc.) in the heating chamber, steam generated from the object to be heated and steam from the steam generating unit installed in the cooking appliance fills the heating chamber 31, causing water droplets to adhere to the heating chamber side surface 31b and heating chamber ceiling. These water droplets flow down from the heating chamber side surface 31b, the heating chamber ceiling, and door 9, and pass through the heating chamber bottom surface 31c to flow near the front frame lower part 33b. The water that has flowed near the front frame lower part 33b flows downward through the gap between the door 9 and the front frame lower part 33b and is collected in the water receiving tray 7.

[0039] At this time, the water receiving tray 7 is attached to the front frame 33 as indicated by the arrow P in FIG. 4(a). The door 9 protrudes forward (in the −Y direction) beyond the gap between the door 9 and the front frame lower portion 33b by at least the thickness of the door 9. Therefore, water that flows downward through the gap between the door 9 and the front frame lower portion 33b can be collected in the water receiving tray 7.

[0040] On the other hand, water that has flowed through heating chamber side surface 31b, heating chamber bottom surface 31c, and heating chamber ceiling surface to the vicinity of front frame lower portion 33b also flows down through front corner holes 33a. Because water also flows down through front corner holes 33a, it is possible to reduce the amount of water that flows down through the gap between door 9 and front frame lower portion 33b.

[0041] In the past, silicone putty was applied to the front corner holes 33a from the back surface of the heating chamber 31 to prevent water from flowing down from the front corner holes 33a, but in this embodiment, the structure allows water to flow down from the front corner holes 33a.

[0042] Fig. 5(a) is a partial front view of the cooking device with the door removed according to the first embodiment, Fig. 5(b) is a see-through view of the partial front view, Fig. 6(a) is a front view of the water receiving plate according to the first embodiment, and Fig. 6(b) is a back view of the same.

[0043] As shown in Figure 5(b), below the heating chamber 31 and on the back surface of the front frame lower part 33b, a water receiving plate 5 that receives water dripping from the front corner holes 33a is provided. As shown in Figure 6, the surface of the water receiving plate 5 is provided with guide parts 5a that extend downward from both ends of the water receiving plate 5 and are arranged at an angle downward, and a water drain hole 5b is provided above the bottom of the guide parts.

[0044] The guide portion 5a is made of a rubber material with waterproofing properties, and by attaching it by screwing or welding so that the surface of the water receiving plate 5 is pressed against the back surface of the lower front frame portion 33b, the guide portion 5a also serves to seal the gap between the water receiving plate 5 and the lower front frame portion 33b.

[0045] With this configuration, water flowing down from the front corner holes 33a passes through the upper surface of the guide portion 5a of the water receiving plate 5 and drains through the drainage holes 5b to the back side of the water receiving plate 5 (see the arrows in Figures 5(b) and 6(a)).

[0046] Although the front corner holes 33a are arranged at the left and right front corners of the heating chamber 31, they may be provided only at the left or right front corner. For example, one front corner hole 33a may be provided, and the other front corner hole 33a may be blocked with silicone putty or the like.

[0047] When configured in this manner, for example, in Figure 6(a), if the front corner hole 33a is provided only on the right side of the heating chamber 31, the guide portion 5a can be provided from the end of the water receiving plate 5 at the right front corner hole 33a to a little to the left of the drain hole 5b, and the guide portion 5a can be tilted downward from the end of the water receiving plate 5 to a position below the drain hole 5b, and tilted upward from the drain hole 5b to the left side, so that the guide portion 5a extends halfway up the left side of the water receiving plate 5.

[0048] 6(b), a water receiving portion 5c is provided below the drainage holes 5b and on the back side of the water receiving plate 5. The water receiving portion 5c is cut out in a substantially triangular shape from the back side of the water receiving plate 5 and configured horizontally, or configured so that the tip 5c2 faces downward, and the shielding portion 5c1 is cut out vertically, so that water that flows down from the drainage holes 5b collects at the tip 5c2 of the water receiving portion 5c and flows down from the tip 5c2.

[0049] 7 is a schematic perspective view of the front frame and bottom plate of the cooking device as seen from behind. As shown in FIG. 7, a recess is provided in the bottom plate 6 of the main body 3 of the cooking device 1 at a position where water flowing down from the tip 5c2 of the water receiving portion 5c is received, and the water that has flowed down into the recess 6a is temporarily collected in the recess and then flows down further from the drain hole 6b provided in the recess 6a (see the arrow in FIG. 7). see).

[0050] Figure 8 is an exploded schematic view of the cooking device and water receiving tray as seen from the bottom front. As shown in Figure 8, a water receiving tray 7a for the water drainage holes is provided in a position to receive water that flows down from the water drainage holes 6b, and the water can ultimately be collected in the water receiving tray 7a for the water drainage holes.

[0051] The water receiving tray 7a for the drainage hole and the tray for collecting water that flows downward through the gap between the door 9 and the lower front frame 33b may be shared by the water receiving tray 7, or may be separate trays. [Industrial Applicability]
