The legs 24 are attached to the lower ends of both sides of the fan case 21. The height of the lower end of each leg 24 is the same as the height of the lower end of the front frame 3a (see FIG. 4).

Next, refer to FIG. FIG. 7 is a front partial perspective view of the lower part of the fan case 21. A water receiving portion 27 for guiding the water that condenses and falls is attached to the lower part of the fan case 21. The water receiving portion 27 is made of metal and is a member separate from the fan case 21. The water receiving portion 27 extends in the longitudinal direction of the fan case 21, has a flat portion 27a parallel to the lower wall portion 21b of the fan case 21, and a groove 27b extending downward from the flat portion 27a and bent forward. Has.

Next, refer to FIG. FIG. 8 is a partial vertical cross-sectional view of the water receiving portion 27 around the joint portion 29. The groove 27b of the water receiving portion 27 has a V-shaped or concave cross section. In particular, when the groove 27b has a V shape, water droplets collect on the bottom of the groove 27b, so that the flow of water in the groove 27b is improved and it is possible to prevent water from overflowing from the groove 27b. The groove 27b of the water receiving portion 27 is located in front of the flat portion 27a. Therefore, the dropped water is guided in the longitudinal direction in front of the fan case 21.

The bottom wall 5e of the heating chamber 5 has a flange portion 25 that is bent downward and extends from the trailing edge portion of the bottom wall 5e. The flange portion 25 is in contact with the lower end portion of the rear wall 5d. The flat portion 27a of the water receiving portion 27 is also parallel to the flange portion 25 of the bottom wall 5e of the heating chamber 5.

The cooking cooker 1 includes a connecting portion 29 that connects the flange portion 25, the lower end portion of the rear wall 5d, the lower wall portion 21b of the fan case 21, and the flat portion 27a of the water receiving portion 27 (FIG. 7). reference). The connecting portion 29 is connected by, for example, caulking, but may also be connected by bolts and nuts. In FIG. 8, caulking is omitted in order to make it easier to understand the cross-sectional shape. As described above, although the water receiving portion 27 is a separate member from the fan case 21, it is integrally coupled with the fan case 21, so that the cooking cooker 1 can be easily assembled. The water receiving portion 27 can be further easily assembled by being integrally molded with the fan case 21.

The flat portion 27a of the water receiving portion 27 is arranged behind the flange portion 25, the lower end portion of the rear wall 5d, and the lower wall portion 21b of the fan case 21 and is coupled to these. Further, the leg portion 24 is arranged at the rearmost portion of the flange portion 25, the lower end portion of the rear wall 5d, the lower wall portion 21b of the fan case 21, and the flat portion 27a, and is coupled to these.

Next, refer to FIG. FIG. 9 is a front view of the lower wall portion 21b of the fan case 21. The groove 27b has a branch point 27c that serves as a starting point that inclines downward to one side (left side) and the other side (right side) in the longitudinal direction. Therefore, in the groove 27b, the height Ha of the branch point 27c is the highest.

The branch point 27c is located on the opposite side of the center of the groove 27b in the longitudinal direction. By locating the branch point 27c on the other side, the amount of water guided to one side can be increased. Since the water guided to one side is finally guided to the first tray 13, the capacity of the drainage water storage unit 15a of the second tray 15 on the other side can be reduced. Further, when the capacity of the first tray is insufficient, the size of the first tray can be reduced by securing the capacity of the water storage unit 15a of the second tray 15.

The height Hb of one end 27d of the groove 27b is lower than the height Hc of the other end 27e of the groove 27b. Since the height of the end 27d on one side of the long flow path is low, even if the amount of water flowing in the groove 27b is large, the water can flow without overflowing.

See FIG. FIG. 10 is a top view of the water receiving portion 27. The groove 27b is curved so that the end portion 27d on one side is located in front of the branch point 27c.

The water droplets condensed in the fan case 21 fall along the fan case 21 due to its own weight, pass through the gap between the fan case 21 and the rear wall 5d of the heating chamber 5, and fall to the groove 27b of the water receiving portion 27. Further, the water droplets condensed on the flange portion 25 of the rear wall 5d and the bottom wall 5e of the heating chamber 5 also fall through the gap between the rear wall 5d and the flange portion 25 to the groove 27b of the water receiving portion 27.

If the drop point of the water droplet is on one side of the branch point of the water receiving portion 27, the water droplet is guided forward along the curvature of the groove 27b while being guided toward the one end portion 27d of the groove 27b. .. Since it is also guided forward, the water falling from one end 27d of the groove 27b has not only a longitudinal velocity component but also a forward velocity component. As a result, it is possible to reduce the amount of water falling from the end portion 27d being scattered in the longitudinal direction.

See FIG. FIG. 11 is an enlarged top view of the other end of the water receiving portion. The groove 27b has a notch 30 between the branch point 27c and the other end 27e, and the groove 27b has a notch 30 from the branch point 27c to the notch 30 and from the other end 27e. Curve forward up to 30.

If the drop point of the water droplet is on the opposite side of the branch point 27c of the water receiving portion 27, the water droplet is guided forward along the curve of the groove 27b while being guided to the notch 30 of the groove 27b. The notch 30 has an inner section 30a located inside in the longitudinal direction of the bent portion of the groove 27b and an outer section 30b located outside. The inner section 30a and the outer section 30b intersect at their respective trailing ends.

When water flows outward in the longitudinal direction and the amount of water guided to the notch 30 is large, when water falls from the inner section 30a, some water collides with the outer section 30b. To do. As a result, it is possible to prevent the water from scattering outward in the longitudinal direction when the water falls, and the falling water is guided downward.

Further, since the notch 30 which is the water discharge port on the other side of the groove 27b is located in front of the branch point 27c due to the curvature, the horizontal trough portion 51 which receives the water discharged from the notch 30 is notched. It can be arranged so as to wrap around to the rear of 30 (see FIG. 20). As a result, it is possible to prevent the water that has fallen from the notch 30 from splashing backward due to rebounding. Further, since the notch 30 is arranged inward from the end portion 27e on the other side, it is possible to realize the miniaturization of the cooking cooker 1 in the longitudinal direction.

Next, with reference to FIG. 12, a flow path for flowing water from one end 27d of the water receiving portion 27 to the first tray 13 via another water receiving portion will be described. FIG. 12 is a front perspective view of the vicinity of one end portion 27d of the water receiving portion 27.

Below the end portion 27d on one side of the groove 27b, another water receiving portion, a horizontal trough portion 31, is arranged. The end portion 27d of the groove 27b and the horizontal trough portion 31 are arranged in non-contact manner, respectively. As a result, since the end portion 27d and the horizontal trough portion 31 are not in contact with each other, the fan case 21 on which the water receiving portion 27 is supported and the heating chamber 5 can be easily attached to and detached from each other. Further, when the heating chamber 5 is removed, the water receiving portion 27 and the horizontal trough portion 31 are not in contact with each other, so that the heating chamber 5 can be easily removed.

Next, refer to FIG. FIG. 13 is a top view of the bottom plate 37. A bottom plate 37 is arranged below the heating chamber 5. The bottom plate 37 is connected to the front frame 3a and the lower end of the fan case 21. The space between the bottom wall 5e of the heating chamber 5 and the bottom plate 37 is used as a machine room. In this machine room, a drive mechanism for driving each function of the cooker 1, a magnetron for generating microwaves (not shown), a magnetron drive power supply for supplying electric power to the magnetron (not shown), and microwaves are provided. A control unit (not shown) that controls the generated operation is arranged. In FIG. 13, the first tray 13 is mounted and the cover of the cooling fan 39 is removed.

The bottom plate 37 has a recess 41 in the center in which a cooling fan 39, a magnetron, and the like are arranged. The recess 41 is formed by press working. The bottom plate 37 has a bottom plate flat portion 43 rising from a recess 41 along the outer circumference. On one side of the flat bottom plate portion 43 in the longitudinal direction, an elongated hole 45 extending in the front-rear direction is provided. A part of the horizontal trough portion 31 projects upward from below the elongated hole 45.

Further, the bottom plate 37 has a gutter cover portion 47 which is arranged in front of the elongated hole 45 and has an arch-shaped cross section. The gutter cover portion 47 gradually rises upward from the bottom plate flat portion 43 toward the rear. The gutter cover portion 47 covers a part of the inclined portion of the horizontal gutter portion 31 that inclines downward from above the bottom plate 37.

Next, reference to FIGS. 14 to 16. FIG. 14 is a top view of the periphery of the horizontal trough portion 31. FIG. 15 is a top view of the periphery of the horizontal trough portion 31 in a state where the bottom plate 37 of FIG. 14 is removed. FIG. 16 is a view looking inward from the cross section of the horizontal trough portion 31 in the XVI-XVI line of FIG.

A horizontal trough portion 31 is arranged below the end portion 27d on one side of the water receiving portion 27. The horizontal trough portion 31 extends from the rear to the front along one side portion of the cooker 1. The horizontal trough portion 31 has a downward inclination angle toward the front. The horizontal trough portion 31 has a first horizontal trough portion 33 arranged below an end portion 27d on one side of the water receiving portion 27, and a second horizontal trough portion 35 extending forward from the front end of the first horizontal trough portion 33. The first horizontal trough portion 33 and the second horizontal trough portion 35 have a substantially linear flow path. The tilt angles of the first horizontal trough portion 33 and the second horizontal trough portion 35 are different from each other, and the tilt angle θ1 of the first horizontal trough portion 33 is larger than the tilt angle θ2 of the second horizontal trough portion 35.

Since the inclination angle θ1 of the first horizontal trough portion 33 of the horizontal trough portion 31 is large, even if the kinetic energy of the water falling from the groove 27b of the water receiving portion 27 is small, it can be accelerated in the inclined direction. As a result, the water can be appropriately guided forward, and it is possible to prevent the water from staying in the horizontal trough portion 31. Further, since the one-sided end portion 27d of the water receiving portion 27 is located above the first horizontal trough portion 33 having a large inclination angle, the first horizontal trough portion 33 can be brought closer to the end portion 27d of the water receiving portion 27. It is possible to reduce the rebound of water that has fallen on the first horizontal trough 33.

The horizontal trough portion 31 has a bottom wall 31a through which water flows and a side wall 31b extending upward from the side edge portion of the bottom wall 31a. The bottom wall 31a has a bottom wall 31aa of the first horizontal trough portion 33 and a bottom wall 31ab of the second horizontal trough portion 35. The side wall 31b has a side wall 31ba of the first horizontal trough portion 33 and a side wall 31bb of the second horizontal trough portion 35. The rear portion of the side wall 31ba of the first horizontal trough portion 33 projects from the lower side to the upper side through an elongated hole 45 formed in the bottom plate 37. Further, the height Hb of the one end portion 27d of the water receiving portion 27 is lower than the height Hd of the upper end of the side wall 31ba of the first horizontal trough portion 33.

Since one end 27d of the water receiving portion 27 is lower than the upper end of the side wall 31ba of the first horizontal trough 33, the bounce when water falls from the water receiving portion 27 to the first horizontal trough portion 33 is the first. 1 It is possible to prevent the horizontal trough portion 33 from popping out. Further, since the side wall 31ba of the first horizontal trough portion 33 is arranged so as to wrap around behind the end portion 27d of the water receiving portion 27, it is possible to prevent water from leaking to the rear due to bounce. Further, since at least a part of the side wall 31ba of the first horizontal trough portion 33 projects from the lower side to the upper side through the elongated hole 45 formed in the bottom plate 37, the inclination angle of the first horizontal trough portion 33 can be increased. Even if the height of the housing 3 is lowered, the water can be smoothly drained forward.

Below the bottom plate 37, a lower frame 49 that supports the bottom plate 37, the first tray 13, and the second tray 15 is arranged. The lower frame 49 supports the horizontal trough portion 31. Further, the front portion of the lower frame 49 has a first tray accommodating portion 49a accommodating the first tray 13 and a second tray accommodating portion 49b (see FIG. 19) accommodating the second tray.

Next, refer to FIG. FIG. 17 is a front perspective view of the periphery of the tip of the horizontal trough. The front end 35a of the second horizontal trough portion 35 extends into the first tray accommodating portion 49a. As a result, when the first tray 13 is mounted on the first tray accommodating portion 49a, the front end 35a of the second horizontal trough portion 35 is located above the rear portion of the first tray 13. Therefore, the water falling from the front end 35a of the second horizontal trough 35 is stored in the first tray 13.

In this way, the water that has fallen from the water receiving portion 27 to the first horizontal trough portion 33 moves while accelerating forward by the first horizontal trough portion 33 having a large inclination angle. Even if water enters the second horizontal trough 35 having a gentle inclination angle, it is sufficiently accelerated, so that it moves forward without staying and falls from the front end 35a of the second horizontal trough 35 into the first tray 13.

Next, with reference to FIGS. 18 and 19, a flow path for flowing water from the notch 30 on the other side of the water receiving portion 27 to the second tray 15 via another water receiving portion will be described. FIG. 18 is a front perspective view around the notch of the water receiving portion. FIG. 19 is a front perspective view showing a flow path of water from the notch of the water receiving portion to the second tray accommodating portion.

The cooking cooker 1 is provided with a horizontal trough 51 that guides the water that has fallen from the notch 30 of the water receiving portion 27 to the second tray 15 on the outer side of the other side. The horizontal trough 51 extends from the rear to the front along one side of the cooker 1. The horizontal trough 51 has a downward inclination angle toward the front. The horizontal trough portion 51 includes a third horizontal trough portion 53 that receives water that has fallen from the notch 30 of the water receiving portion 27, and a fourth horizontal trough portion 55 that receives water that falls from the front portion of the third horizontal trough portion 53.

Next, refer to FIG. FIG. 20 is a front perspective view showing a guide portion 53a that receives water falling from the notch 30 of the water receiving portion 27. The third horizontal gutter portion 53 has a guide portion 53a extending linearly in the front-rear direction and a vertical gutter portion 53b extending in the vertical direction. The rear end of the guide portion 53a is located behind the notch 30 of the water receiving portion 27. The guide portion 53a has a concave cross section, but may have a V shape. The guide portion 53a has a downward inclination toward the front.

At the front of the guide portion 53a, the flow path bends outward and is connected to the downspout portion 53b. The downspout portion 53b extends downward through a hole 57 formed in a flat portion 27a on the other side in the longitudinal direction of the bottom plate 37. A fourth gutter portion 55 is arranged below the downspout portion 53b.

See FIG. The fourth horizontal trough portion 55 is arranged along the other side portion of the lower frame 49. The rear end portion 55a of the fourth gutter portion 55 is located below the downspout portion 53b. The fourth horizontal trough portion 55 has a downward inclination toward the front. The front end 55b of the fourth horizontal trough portion 55 extends into the second tray accommodating portion 49b. As a result, when the second tray 15 is mounted on the second tray accommodating portion 49b, the front end 55b of the fourth horizontal trough portion 55 is located above the rear portion of the second tray 15. A water storage portion 15a for accommodating water flowing down from the horizontal trough 51 is provided on the front outer side of the second tray 15 (see FIG. 21), and the water falling from the front end 55b of the fourth horizontal trough 55 is second. It is housed in the tray 15.

The water that has fallen from the notch 30 of the water receiving portion 27 flows forward along the guide portion 53a to the downspout portion 53b. The water flowing in the downspout portion 53b is guided downward and falls on the fourth downspout portion 55 arranged below the bottom plate 37. The water that has fallen on the fourth horizontal trough 55 is guided down the fourth horizontal trough 55 forward along the inclination to the second tray 15.

Next, with reference to FIGS. 22 to 25, the configuration below the front end 35a of the second horizontal trough portion 35 and the front end 55b of the fourth horizontal trough portion 55 will be described. FIG. 22 is a front perspective view of the vicinity of the front end 35a of the second horizontal trough portion 35. FIG. 23 is a vertical cross-sectional view cut in the front-rear direction around the front end 35a of the second horizontal trough portion 35. FIG. 24 is a front perspective view of the vicinity of the front end 55b of the fourth horizontal trough portion 55.

The cooking cooker 1 provided with the heating chamber 5 has a rear wall 5d arranged at the rear part of the heating chamber 5, a bottom wall 5e arranged at the lower part of the heating chamber 5, and a rear wall arranged behind the rear wall 5d. A fan 17 for circulating air in the heating chamber 5 through a hole formed in 5d is provided. Further, the cooking cooker 1 is separate from the fan case 21 that covers the rear of the fan 17 and receives water that falls downward along at least one of the rear wall 5d and the fan case 21. A water receiving unit 27 is provided. The bottom wall 5e has a flange portion 25 extending downward from the trailing edge portion of the bottom wall 5e. The water receiving portion 27 has a flat portion 27a extending in the longitudinal direction of the rear wall 5d and parallel to the flange portion 25, and a groove 27b extending downward from the flat portion 27a and bent forward. The cooking cooker 1 includes a connecting portion 29 that connects the flange portion 25, the lower portion of the rear wall 5d of the heating chamber 5, the lower portion of the fan case 21, and the flat portion 27a of the water receiving portion 27. The flat portion 27a of the water receiving portion 27 is connected so as to be located behind the flange portion 25, the lower portion of the rear wall 5d, and the lower portion of the fan case 21, and the groove 27b of the water receiving portion 27 is unilaterally and in the longitudinal direction. The groove 27b has a branch point 27c as a starting point that inclines downward toward the other, and the groove 27b is curved so that the end portion 27d on one side is located in front of the branch point 27c. The following effects can be obtained from such a configuration.

Since the water receiving portion 27 is a separate member from the fan case 21, the degree of freedom in the shape of the water receiving portion 27 can be increased. This makes it possible to facilitate processing such that the groove 27b is curved forward. Since the curved water receiving portion 27 is coupled to the fan case 21, it is easy to align the water receiving portion 27 in the front-rear direction at the time of assembly. Further, even if the coupling portion 29 has a gap such as a caulking bond, water droplets can flow to the water receiving portion 27 through the gap and stay in the fan case 21 and the heating chamber 5. Can be reduced. Further, since the groove 27b is curved forward, the water falling from the end portion 27d on one side has a velocity component in the forward direction, so that the scattering of water in the longitudinal direction can be reduced. Further, since the groove 27b is curved forward, another water receiver that overhangs the rear of the groove 27b can be arranged, and the scattering of water to the rear can be reduced. This reduces the need to separately provide a shatterproof structure on the outside in the longitudinal direction, so that the cooking cooker 1 can be miniaturized in the longitudinal direction.

Further, the branch point 27c of the water receiving portion 27 is located on the opposite side of the center of the groove 27b in the longitudinal direction. As a result, the amount of water flowing in the groove 27b on one side can be made larger than that on the other side. As a result, the capacity of the water storage portion 15a of the second tray arranged on the other side can be made smaller than the capacity of the first tray 13.

Further, since the end portion 27d of the groove 27b on one side is lower than the end portion 27e of the groove 27b on the other side, the height of the end portion 27d of the groove 27b on the side having a long flow path is low. As a result, the end portion 27d of the groove 27b on the side where the flow path is long can be brought closer to the next water receiving portion, so that even if the amount of water flowing in the groove 27b is large, water can flow smoothly to the next water receiving portion. Can be done.

Further, the cooking cooker 1 includes a water supply tank 14 for supplying water to the steam generator 16, and the water supply tank 14 is arranged on the other side of the cooking cooker 1. As a result, the water supply tank 14 is arranged in front of the branch point 27c of the groove 27b. Since the branch point 27c is arranged on the side where the water supply tank 14 is arranged, the amount of water guided to the second tray 15 accommodating the water supply tank 14 can be reduced. As a result, the capacity of the water storage unit 15a of the second tray 15 can be reduced, so that the capacity of the water supply tank 14 can be secured.

Further, the cooking cooker 1 provided with the heating chamber 5 is arranged behind the rear wall 5d arranged at the rear of the heating chamber 5, the bottom wall 5e arranged at the lower part of the heating chamber 5, and the rear wall 5d.

As a result, in the state where the tray 10 is removed, the water flowing down from the horizontal trough portions 31 and 55 can be stored in the recesses 59a and 59b. Therefore, it is possible to prevent water from falling on the mounting surface of the cooking cooker 1 when the tray 10 is removed. Further, the water accumulated in the depressions 59a and 59b can be removed by natural evaporation.

Further, the recesses 59a and 59b have inclined portions 61a and 61b which are inclined obliquely downward toward the front below the front ends 35a and 55b of the lateral trough portions 31 and 55.

As a result, the height difference between the front ends 35a and 55b of the horizontal troughs 31 and 55 and the place where the water falls can be reduced, so that the water flowing down from the front ends 35a and 55b of the horizontal troughs 31 and 55 falls into the recesses 59a and 59b. It is possible to suppress the scattering of water at the time of doing so.

Further, the recesses 59a and 59b have front surfaces 60a and 60b extending upward from the rear ends of the recesses 59a and 59b, and the front ends 35a and 55b of the lateral troughs 31 and 55 are arranged in front of the front surfaces 60a and 60b. To.
