Abstract
Description
[Technical Field]
[0001] The present invention relates to a cooking device. [Background technology]
[0002] Cooking appliances equipped with a drip tray to prevent water remaining inside the cooking appliance from spilling onto the installation base are known. The cooking appliance described in Patent Document 1 is equipped with a dew receiver attached to two front legs. On both sides of the dew receiver, a curved arm portion and a guide portion are provided for attaching the dew receiver to the front legs. When attaching the dew receiver to the front legs, the curved arms elastically deform to cooperate with the guide portions to clamp the front legs. As a result, the dew receiver is held in place by the front legs. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-52703 Summary of the Invention [Problem to be solved by the invention]
[0004] The curved arm of the cooking device in Patent Document 1 has a gently curved shape. In other words, the degree of curvature is small, and the degree of deformation is also small. Therefore, when attaching or detaching the dew receiver, it is sometimes difficult to alleviate the stress generated in the curved arm and reduce the force required to attach or detach the dew receiver.
[0005] An object of the present invention is to provide a cooking device in which the drip tray is easier to attach and detach than conventional cooking devices and in which the strength of the drip tray is improved. [Means for solving the problem]
[0006] According to one aspect of the present invention, a cooking appliance includes a housing having an opening, legs, and a drip tray. The legs are located at the bottom of the housing and near the opening. The drip tray is detachable from the legs. The drip tray has a holding portion. The holding portion protrudes from the outer surface of the drip tray toward the legs and attaches and holds the drip tray to the legs. The holding portion has a first curved portion and a second curved portion. The first curved portion is curved from the protruding direction toward a side of the protruding direction. The second curved portion is located at a position farther from the outer surface of the drip tray than the first curved portion and is curved in a different direction from the first curved portion. The radius of curvature of the first curved portion is smaller than the radius of curvature of the second curved portion. [Effects of the Invention]
[0007] According to the cooking device of the present invention, the drip tray can be attached and detached more easily than in conventional cooking devices, and the strength of the drip tray can also be improved. [Brief explanation of the drawings]

[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 characters and detailed description thereof will not be repeated.
[0010] <Embodiment> First, an overview of a cooking device 100 according to this embodiment will be described. Fig. 1 is a perspective view of the cooking device 100 according to this embodiment. As shown in this figure, the cooking device 100 comprises a housing 10, at least a pair of legs 20, 20, and a drip tray 30. The drip tray 30 comprises a holding part 50. The holding part 50 enables the drip tray 30 to be attached to and detached from the pair of legs 20, 20 and held therein.
[0011] In the cooking appliance 100 of this embodiment, the shape of the holding portion 50 of the drip tray 30 (described later) is curved to a greater degree than conventional ones. This reduces the stress that occurs in the holding portion 50 when attaching or detaching the drip tray 30 to or from the leg portion 20. By reducing the stress, the force required for attachment or detachment is reduced, making it easier to attach or detach the drip tray 30, and the strength of the holding portion 50 can also be improved.
[0012] The cooking device 100 may also be in the form of a microwave oven equipped with a magnetron (not shown). The magnetron supplies microwaves to the heating chamber 11 in which an object to be heated is accommodated. The magnetron is an example of a microwave generator. The cooking device 100 according to this embodiment may have the functions of either a microwave oven or an oven, or both.
[0013] Next, each component will be described in detail. The housing 10 shown in Fig. 1 has a generally rectangular parallelepiped shape with an open front. A heating chamber 11 is provided inside the housing 10. The heating chamber 11 has an opening 12 formed on the front. A user puts an object to be heated in and takes it out of the heating chamber 11 through the opening 12. This opening 12 is opened and closed by a door 13. The door 13 is attached to the housing 10 so as to be rotatable around a horizontal axis defined by a lower edge 10a of the housing 10.
[0014] The cooking appliance 100 further includes a pair of legs 20, 20. The pair of legs 20, 20 are provided on the bottom 14 of the housing 10, near the opening 12, i.e., on the lower front side of the housing 10. The shape of the legs 20 may be any shape as long as the drip tray 30 can be attached to the legs 20, and in this embodiment they are columnar. Note that the housing 10 may also be provided with another pair of legs at the rear, making a total of four legs on the front, back, left and right.
[0015] 2 is a perspective view of a part of the drip tray 30 and the leg portion 20 of the cooking appliance 100 shown in FIG. 1, viewed from the rear. As shown in this figure, the leg portion 20 has a first side surface 21 and a second side surface 22. The first side surface 21 faces the outside of the cooking appliance 100. The second side surface 22 faces the inside of the cooking appliance 100.
[0016] The first side surface 21 has a first receiving portion 24. The first receiving portion 24 is a member that receives the holding portion 50 of the drip tray 30. As an example, the first receiving portion 24 is a recess that is roughly U-shaped in cross section. A first groove wall 24a is formed at the top of the first receiving portion 24, and a second groove wall 24b is formed at the bottom. The first groove wall 24a and the second groove wall 24b may have any shape. In this embodiment, the first groove wall 24a is formed so as to slope downward toward the rear of the leg 20. The second groove wall 24b is formed horizontally. In other words, the first receiving portion 24 has a shape that tapers toward the rear of the leg 20.
[0017] The first receiving portion 24 further has a groove bottom surface 23 and a protrusion 24c. The groove bottom surface 23 is provided between the first groove wall 24a and the second groove wall 24b. The protrusion 24c protrudes from the groove bottom surface 23 toward the first side surface 21. The protrusion 24c is provided, for example, at a position closer to the front surface of the leg portion 20.
[0018] The second side surface 22 also has a second receiving portion 25. The second receiving portion 25 is a member that receives the guide portion 60, which will be described later. The second receiving portion 25 may have any shape as long as it can receive the guide portion 60, and in this embodiment, it is a recess that is roughly U-shaped in cross section.
[0019] The cooking appliance 100 further includes a drip tray 30. The drip tray 30 shown in FIG. 1 has a bottom with an open top 41. The drip tray 30 may be made of any material, and in this embodiment is made of resin. By attaching and holding the drip tray 30 to the legs 20, 20, water generated in the heating chamber 11 can be collected.
[0020] The drip tray 30 has a water receiving portion 40 and a pair of holding portions 50, 50. The water receiving portion 40 is roughly rectangular parallelepiped shaped along the side 10a of the housing 10. An upper portion 41 of the water receiving portion 40 is open. When the drip tray 30 is attached to the legs 20, 20, the water receiving portion 40 is positioned below the door 13. It receives water generated within the heating chamber 11, for example, water that drips down from the surface of the door 13 that covers the opening 12.
[0021] Next, the pair of holders 50 will be described. The pair of holders 50 are provided on both sides of the outer surface 42 on the rear side of the water receiving portion 40, i.e., the surface facing the leg portion 20. However, the holders 50 of this embodiment are not limited to being provided on both sides of the water receiving portion 40. One holder 50 may be provided on either side, and a conventional one may be used on the other.
[0022] 2, the holding portion 50 is a member that is received by the first receiving portion 24 of the leg portion 20 and holds the drip tray 30 to the leg portion 20. A recess 43 is formed in the portion of the outer surface 42 that corresponds to the leg portion 20. The holding portion 50 protrudes from the outer surface 42 toward the leg portion 20 at the recess 43.
[0023] The shape of the holding portion 50 may be any shape, and in this embodiment, it is generally tongue-shaped. The top surface 50a of the holding portion 50 is inclined toward the tip of the holding portion 50 to correspond to the first groove wall 24a of the first receiving portion 24. In other words, the holding portion 50 is inclined so that the width of the holding portion 50 decreases toward the tip. The bottom surface 50b of the holding portion 50 extends horizontally to correspond to the second groove wall 24b.
[0024] The holding portion 50 is molded integrally with the water receiving portion 40. However, the holding portion 50 of this embodiment is not limited to being molded integrally with the water receiving portion 40, and may be produced as a separate member.
[0025] Next, a specific example of the holding part 50 will be described. Fig. 3 is a plan view of the holding part 50 of the drip tray 30 shown in Fig. 2. As shown in this figure, the holding part 50 has a first curved part 51 and a second curved part 52. The first curved part 51 is curved from the protruding direction of the holding part 50 toward the side (to the right in Fig. 3) of the protruding direction. In other words, when the holding part 50 is attached to the leg part 20, the first curved part 51 is curved in a direction away from the leg part 20.
[0026] The second curved portion 52 is provided at a position farther from the outer surface 42 than the first curved portion 51. The second curved portion 52 is curved in a direction different from that of the first curved portion 51. Here, "a different direction" does not mean only the direction opposite to the direction in which the first curved portion 51 is curved.
[0027] The radius of curvature of the first curved portion 51 is smaller than the radius of curvature of the second curved portion 52. In other words, the degree of curvature of the first curved portion 51 is greater than that of conventional ones.
[0028] Therefore, when attaching the drip tray 30 to the leg portion 20, stress is alleviated at the first curved portion 51 more easily than in conventional cases, making the holding portion 50 more flexible. As a result, the force required to attach and detach the drip tray 30 can be reduced, making it even easier to attach and detach the drip tray 30 than in conventional cases.
[0029] The drip tray 30 also receives and stores water from inside the cooker 100 while attached to and held by the legs 20. Therefore, if a large force is applied when removing the drip tray 30, it may shake violently, causing the water inside to spill. In contrast, the holding part 50 of this embodiment reduces the force required to attach and detach the drip tray 30, as described above. As a result, water is less likely to spill when removing the drip tray 30, improving convenience.
[0030] Furthermore, by mitigating the stress generated in the holding part 50 when attaching and detaching the drip tray 30, the strength of the holding part 50 is improved, making it possible for the holding part 50 to withstand a considerable number of repeated attachments and detachments. Furthermore, it is also possible to make the holding part 50 less prone to wear.
[0031] In this embodiment, the first curved portion 51 is located closer to the outer surface 42. The holding portion 50 is designed to bend laterally from the first curved portion 51 when the drip tray 30 is attached or detached. Therefore, by forming the first curved portion 51 closer to the outer surface 42, the holding portion 50 is bent from its base, making it easier to open the holding portion 50 laterally. However, the holding portion 50 of this embodiment is not limited to being formed closer to the outer surface 42. The first curved portion 51 may be formed, for example, closer to the tip of the holding portion 50.
[0032] The retaining portion 50 further has a rising portion 53, a first linear portion 54, and a second linear portion 55. The rising portion 53 protrudes in a generally vertical direction from the outer surface 42. The first linear portion 54 is continuous with the rising portion 53 and extends generally laterally from the rising portion 53. In other words, the first linear portion 54 is provided between the first curved portion 51 and the outer surface 42. Here, in this specification, the term "linear portion" does not only refer to a portion that extends straight, but may also include a slightly curved portion.
[0033] The second linear portion 55 is provided between the first curved portion 51 and the second curved portion 52. The second linear portion 55 extends in the front-rear direction away from the first linear portion 54. The second linear portion 55 is continuous with the second curved portion 52. However, in the holding portion 50 of this embodiment, the extending direction, inclination, length, etc. of the first linear portion 54 and the second linear portion 55 can be changed as appropriate depending on the shape of the first receiving portion 24 of the leg 20 to be attached.
[0034] In this way, by providing first linear portion 54 and second linear portion 55, first curved portion 51 is curved more to the side, increasing the bending portion, thereby making it possible to easily attach and detach drip tray 30.
[0035] The second curved portion 52 has a 2-1 curved portion 52a, a third linear portion 52b, a fourth linear portion 52c, and a fifth linear portion 52d. The 2-1 curved portion 52a is continuous with the second linear portion 55 and curves inward (toward the left in FIG. 3). The third linear portion 52b is continuous with the 2-1 curved portion 52a.
[0036] The fourth linear portion 52c continues from the third linear portion 52b. As will be described later, an inner surface 52ca (on the left side in FIG. 3) of this fourth linear portion 52c comes into contact with the first receiving portion 24 of the leg portion 20 to hold the drip tray 30 to the leg portion 20. The fifth linear portion 52d continues from the fourth linear portion 52c. The fifth linear portion 52d extends at an angle outward (to the right side in FIG. 3) from the direction in which the fourth linear portion 52c extends.
[0037] The 2-1 curved portion 52a, the third linear portion 52b, the fourth linear portion 52c, and the fifth linear portion 52d form the second curved portion 52, which has a larger radius of curvature than the first curved portion 51. However, the second curved portion 52 is not limited to the above-described configuration. The shape of the second curved portion 52 may be changed as appropriate depending on the shape of the first receiving portion 24 of the leg 20 to which the holding portion 50 is attached. For example, the lengths of the third linear portion 52b and the fourth linear portion 52c may be changed depending on the shape of the first receiving portion 24, or the third linear portion 52b may be omitted.
[0038] The drip tray 30 may also include a guide portion 60, as illustrated in Figure 2. In this embodiment, a pair of guide portions 60, 60 are provided at positions facing the pair of holders 50, 50, respectively. Each guide portion 60 protrudes from the outer surface 42 toward the leg portion 20 in the recess 43 of the water receiving portion 40. It is then received by the second receiving portion 25 of the leg portion 20.
[0039] When the second receiving portion 25 receives the guide portion 60, the second receiving portion 25 and the guide portion 60 are not in close contact with each other, and a space may or may not be provided between them. In this embodiment, the guide portion 60 is not housed in close contact with the inside of the second receiving portion 25. A small space is formed between the guide portion 60 and the second receiving portion 25.
[0040] By providing the guide portion 60, the holder 50 can be attached to the leg portion 20 while being guided by the guide portion 60. This allows the drip tray 30 to be attached smoothly. The guide portion 60 also prevents vibration when the drip tray 30 is pressed hard left or right.
[0041] Next, a method for attaching the drip tray 30 to the leg part 20 will be described with reference to Figures 4 to 7. Figure 4 is an explanatory diagram showing the state before the holder 50 shown in Figure 3 is attached to the leg part 20, as viewed from the bottom side. Figure 5 is a diagram showing the movement of the holder 50 shown in Figure 4 when it is attached to the leg part 20. Figure 6 is a diagram showing the state after the holder 50 shown in Figure 5 has been attached to the leg part 20. Figure 7 is a perspective view showing the state after the drip tray 30 shown in Figure 2 has been attached to the leg part 20.
[0042] As shown in Fig. 4, when the drip tray 30 is not attached to the leg 20, the holder 50 protrudes in a generally vertical direction. In this state, the drip tray 30 is brought closer to the leg 20. Then, as shown in Fig. 5, the holder 50 of the drip tray 30 is attached to the first receiving portion 24 of the leg 20. Specifically, the top surface 50a of the holder 50 is brought into contact with the first groove wall 24a in Fig. 2. Meanwhile, the bottom surface 50b of the holder 50 is brought into contact with the second groove wall 24b.
[0043] Thereafter, the holding portion 50 is moved toward the back of the leg portion 20 along the first groove wall 24a and the second groove wall 24b. The holding portion 50 in FIG. 5 is then bent and deformed by the first curved portion 51 from the state shown in FIG. 4, and moves laterally, that is, in the direction of the arrow in FIG. 5. The distance that the holding portion 50 moves can be set appropriately. In this embodiment, it is set to about 2 mm.
[0044] As described above, the large degree of curvature of the first curved portion 51 can alleviate the stress generated in the holding portion 50. This reduces the force required to attach the holding portion 50. As a result, the holding portion 50 can be easily attached to the leg portion 20. For example, the force required to deform the holding portion 50 as shown in FIG. 5 can be reduced to about half of that required in the prior art.
[0045] Furthermore, by deforming and moving sideways, the holding portion 50 allows the tip portions of the holding portion 50, such as the fifth linear portion 52d, the fourth linear portion 52c, and the third linear portion 52b, to pass smoothly while avoiding the protrusion portion 24c.
[0046] Thereafter, the further the holding portion 50 goes in, the smaller the gap between the first groove wall 24a and the upper surface 50a of the holding portion 50. Eventually, the holding portion 50 is sandwiched between the first groove wall 24a and the second groove wall 24b and fixed to the first receiving portion 24, resulting in the state shown in Figures 6 and 7.
[0047] As illustrated in FIG. 6, after the tip portion of the holding portion 50 passes through the protrusion 24c, the protrusion 24c is housed in the internal space of the holding portion 50, for example, from the third linear portion 52b of the second curved portion 52 to the first curved portion 51. At this time, the protrusion 24c does not need to fit snugly along the internal shape of the holding portion 50. In other words, it is sufficient that a specific portion of the holding portion 50 contacts the protrusion 24c. In this embodiment, a certain amount of space is formed between the protrusion 24c and the inner surface of the holding portion 50.
[0048] After the tip of the holding portion 50 passes the protrusion 24c, the inner surface 52ca of the fourth linear portion 52c comes into contact with the groove bottom surface 23. Then, as illustrated in Figures 6 and 7, the fourth linear portion 52c embraces the leg portion 20, thereby holding the drip tray 30 to the leg portion 20.
[0049] On the other hand, to remove the drip tray 30 from the leg portion 20, simply pull the drip tray 30 in the direction opposite to the attachment direction from the state shown in Figures 6 and 7. In this case, the first curved portion 51 also bends as described above, making removal easier.
[0050] The embodiments of the present invention have been described above with reference to the drawings. However, the present invention is not limited to the above embodiments and can be embodied in various forms without departing from the spirit and scope of the present invention. The drawings mainly show each component in a schematic manner for ease of understanding, and the thickness, length, number, spacing, etc. of each component shown in the drawings may differ from the actual ones due to the convenience of creating the drawings. Furthermore, the materials, shapes, dimensions, etc. of each component shown in the above embodiments are merely examples and are not particularly limited, and various modifications are possible within a scope that does not substantially deviate from the configuration of the present invention.
