The display unit 9 is a liquid crystal screen, for example, and displays a menu screen or the like. The operation unit 11 is, for example, a push button or a dial. The user gives various cooking instructions to the heating cooker 1 using the operation unit 11.

  Below the housing 3, a first tray 13 and a second tray 15 that are detachable in the front-rear direction are disposed on a lower frame 49 coupled to the lower end of the housing 3. The first tray 13 and the second tray 15 are arranged side by side in the longitudinal direction. For example, the first tray 13 is disposed on one side (left side) in the longitudinal direction, and the second tray 15 is disposed on the other side (right side) in the longitudinal direction. The first tray 13 is, for example, a tray for collecting water droplets condensed in the heating cooker 1. The 2nd tray 15 accommodates the water supply tank 14 which supplies water to the steam generator 16 (refer FIG. 21). Further, the second tray 15 has a water storage portion 15 a that collects water droplets condensed in the housing 3.

  Reference is now made to FIGS. FIG. 5 is a front view of the rear wall 5d of the heating chamber 5 to which the fan case 21 is attached. FIG. 6 is a front perspective view of the fan case 21. A fan 17 is disposed behind the rear wall 5d. Further, the rear wall 5 d has a plurality of intake holes 19 and exhaust holes 20 that are opened to circulate the air in the heating chamber 5 by the fan 17.

  The fan case 21 includes a recess 21 a that rotatably supports the fan 17, and a flat lower wall portion 21 b that rises from the recess 21 a and is formed at the lower portion of the fan case 21. The fan case 21 covers the back of the circulation fan 17. The fan case 21 is attached to the rear wall 5d.

  A sheathed heater 23 is arranged along the rotation direction of the fan 17. When the fan 17 is driven to rotate, the air in the heating chamber 5 is sucked from the intake hole 19. The sucked air is heated by the sheathed heater 23 and returns to the heating chamber 5 through the exhaust hole 20. The fan 17 and the sheathed heater 23 constitute a convection heater.

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

  Reference is now made to FIG. FIG. 7 is a front partial perspective view of the lower portion of the fan case 21. A water receiving portion 27 that guides water that is condensed and falls is attached to the lower portion of the fan case 21. The water receiver 27 is made of metal and is a separate member from the fan case 21. The water receiving portion 27 extends in the longitudinal direction of the fan case 21 and is 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. Have

  Reference is now made to FIG. FIG. 8 is a partial longitudinal sectional view of the periphery of the coupling portion 29 of the water receiving portion 27. The groove 27b of the water receiving portion 27 has a V-shaped or recessed shape in cross section. In particular, when the groove 27b has a V-shape, water droplets collect at the bottom of the groove 27b, so that the water flow in the groove 27b is improved and water can be prevented 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 from the rear edge portion of the bottom wall 5e and extends. The flange portion 25 is in contact with the lower end portion of the rear wall 5d. The flat portion 27 a of the water receiving portion 27 is also parallel to the flange portion 25 of the bottom wall 5 e of the heating chamber 5.

  The heating cooker 1 includes a coupling portion 29 that couples 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 coupling portion 29 is coupled by caulking, for example, but may be coupled by bolts and nuts. In FIG. 8, caulking is omitted for easy understanding of the cross-sectional shape. Thus, although the water receiver 27 is a separate member from the fan case 21, it is integrated with the fan case 21, so that the heating cooker 1 can be easily assembled. In addition, the water receiving part 27 can be further simplified by forming it integrally with the fan case 21.

  The flat portion 27a of the water receiving portion 27 is disposed 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 thereto. Further, the leg portion 24 is disposed at the rear end 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 coupled thereto.

  Reference is now made to FIG. FIG. 9 is a front view of the lower wall portion 21 b of the fan case 21. The groove 27b has a branching point 27c serving as a starting point that inclines downward toward one (left side) and the other (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 other side of the center of the groove 27b in the longitudinal direction. By positioning 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 water storage portion 15 a for drainage of the second tray 15 on the other side can be reduced. Moreover, when there is no room in the capacity | capacitance of a 1st tray, a 1st tray can also be reduced in size by ensuring the capacity | capacitance of the water storage part 15a of the 2nd tray 15. FIG.

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

  Please refer to FIG. FIG. 10 is a top view of the water receiver 27. The groove 27b is curved so that one end portion 27d is positioned forward 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, and fall into the groove 27b of the water receiving portion 27 through the gap between the fan case 21 and the rear wall 5d of the heating chamber 5. Further, water droplets condensed on the flange portion 25 of the rear wall 5d and the bottom wall 5e of the heating chamber 5 also drop to the groove 27b of the water receiving portion 27 through the gap between the rear wall 5d and the flange portion 25.

  If the water drop falls on one side of the branch point of the water receiving portion 27, it is guided forward along the curve of the groove 27b while being guided toward the end portion 27d on one side of the groove 27b. . Since it is also guided forward, the water falling from the end 27d on one side of the groove 27b has not only a velocity component in the longitudinal direction but also a velocity component in the forward direction. Thereby, it can reduce that the water which falls from the edge part 27d is scattered in a longitudinal direction.

  Please refer to 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 extends from the branch point 27c to the notch 30 and from the other end 27e. Curves forward to 30.

  If the water drop falls on the other side of the branch point 27c of the water receiving portion 27, the water drop 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 positioned on the inner side in the longitudinal direction of the bent portion of the groove 27b and an outer section 30b positioned on the outer side. The inner section 30a and the outer section 30b intersect at their rear ends.

  When the water flows outward in the longitudinal direction and the amount of water guided to the notch 30 is large, when the water falls from the inner section 30a, some of the water collides with the outer section 30b. To do. Thereby, when water falls, scattering of water to the outside in the longitudinal direction can be prevented, and the falling water is guided downward.

  Moreover, the notch 30 which is the water discharge port on the other side of the groove 27b is positioned forward of the branch point 27c due to the curvature, so that the horizontal flange 51 which receives the water discharged from the notch 30 is notched. It can wrap around to the back of 30 and can arrange (refer to Drawing 20). Thereby, it can prevent that the water which fell from the notch 30 splashes back by splashing back. Moreover, since the notch 30 is arrange | positioned inward rather than the edge part 27e of the other side, size reduction of the cooking-by-heating machine 1 is realizable about a longitudinal direction.

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

  Under the end portion 27d on one side of the groove 27b, a recumbent portion 31 that is another water receiving portion is disposed. The end portion 27d of the groove 27b and the horizontal flange portion 31 are disposed in a non-contact manner. Thereby, since the edge part 27d and the recumbent part 31 are non-contacting, attachment / detachment with the fan case 21 and the heating chamber 5 in which the water receiving part 27 is supported becomes easy. Moreover, when removing the heating chamber 5, since the water receiving part 27 and the recumbent part 31 are non-contacting, it can remove easily.

  Reference is now made to FIG. FIG. 13 is a top view of the bottom plate 37. A bottom plate 37 is disposed below the heating chamber 5. The bottom plate 37 is connected to the front frame 3 a and the lower end of the fan case 21. A space between the bottom wall 5e of the heating chamber 5 and the bottom plate 37 is used as a machine room. This machine room includes a drive mechanism for driving each function of the cooking device 1, a magnetron (not shown) for generating a microwave, a magnetron drive power supply (not shown) for supplying power to the magnetron, and a microwave. A control unit (not shown) for controlling the generation operation and the like 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 at the center where a cooling fan 39, a magnetron, and the like are disposed. The recess 41 is formed by press working. The bottom plate 37 has a bottom plate flat portion 43 that rises from the recess 41 along the outer periphery. One side of the bottom plate flat portion 43 in the longitudinal direction has a long hole 45 extending in the front-rear direction. A part of the horizontal flange 31 protrudes upward from below the long hole 45.

  In addition, the bottom plate 37 includes a heel cover portion 47 that is disposed in front of the long hole 45 and has an arch shape in cross section. The eaves cover portion 47 gradually rises upward from the bottom plate flat portion 43 toward the rear. The eaves cover portion 47 covers a part of the inclined portion of the lateral eaves portion 31 that is inclined downward from above the bottom plate 37.

  Reference is now made to FIGS. FIG. 14 is a top view of the periphery of the recumbent part 31. FIG. 15 is a top view of the periphery of the recumbent portion 31 with the bottom plate 37 of FIG. 14 removed. FIG. 16 is a view of the inner side from a cross section of the recumbent portion 31 taken along the line XVI-XVI of FIG.

  A recumbent portion 31 is disposed below one end portion 27 d of the water receiving portion 27. The recumbent portion 31 extends from the rear to the front along the side portion on one side of the heating cooker 1. The recumbent part 31 has a downward inclination angle toward the front. The recumbent portion 31 includes a first recumbent portion 33 disposed below one end portion 27 d of the water receiving portion 27, and a second recumbent portion 35 extending forward from the front end of the first recumbent portion 33. The 1st recumbent part 33 and the 2nd recumbent part 35 have a substantially linear flow path. The inclination angles of the first lying portion 33 and the second lying portion 35 are different from each other, and the inclination angle θ1 of the first lying portion 33 is larger than the inclination angle θ2 of the second lying portion 35.

  Since the inclination angle θ1 of the first recumbent portion 33 of the recumbent portion 31 is large, even if the kinetic energy of the water dropped from the groove 27b of the water receiving portion 27 is small, it can be accelerated in the inclination direction. Thereby, water can be appropriately guided forward and water can be prevented from staying in the recumbent part 31. In addition, since one end 27d of the water receiving portion 27 is located above the first recumbent portion 33 having a large inclination angle, the first recumbent portion 33 can be brought closer to the end 27d of the water receiving portion 27, The rebound of water that has fallen on the first recumbent portion 33 can be reduced.

  The recumbent portion 31 has a bottom wall 31a through which water flows and a side wall 31b extending upward from a side edge of the bottom wall 31a. The bottom wall 31 a includes a bottom wall 31 aa of the first recumbent portion 33 and a bottom wall 31 ab of the second recumbent portion 35. The side wall 31b includes a side wall 31ba of the first recumbent portion 33 and a side wall 31bb of the second recumbent portion 35. The rear portion of the side wall 31ba of the first horizontal flange 33 protrudes upward from below through a long hole 45 formed in the bottom plate 37. Further, the height Hb of the end portion 27d on one side of the water receiving portion 27 is lower than the height Hd of the upper end of the side wall 31ba of the first recumbent 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 recumbent portion 33, the rebound when water falls from the water receiving portion 27 to the first recumbent portion 33 is It is possible to prevent the one recumbent portion 33 from popping out. In addition, since the side wall 31ba of the first recumbent portion 33 is disposed so as to wrap around the rear portion 27d of the water receiving portion 27, it is possible to prevent water from leaking backward due to rebound. Moreover, since at least a part of the side wall 31ba of the first recumbent portion 33 protrudes upward from below through the long hole 45 opened in the bottom plate 37, the inclination angle of the first recumbent 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 disposed. The lower frame 49 supports the recumbent part 31. In addition, the front portion of the lower frame 49 includes a first tray accommodating portion 49a that accommodates the first tray 13 and a second tray accommodating portion 49b (see FIG. 19) that accommodates the second tray.

  Reference is now made to FIG. FIG. 17 is a front perspective view of the periphery of the tip of the recumbent part. The front end 35a of the second recumbent portion 35 extends into the first tray accommodating portion 49a. As a result, when the first tray 13 is mounted in the first tray accommodating portion 49a, the front end 35a of the second recumbent portion 35 is located above the rear portion of the first tray 13. Therefore, the water falling from the front end 35 a of the second recumbent part 35 is accommodated in the first tray 13.

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

  Next, with reference to FIG. 18 and FIG. 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 heating cooker 1 includes a recumbent portion 51 that guides water that has dropped from the notch 30 of the water receiving portion 27 to the second tray 15 on the outer side of the other side.

The rear end of the guide portion 53 a is located behind the notch 30 of the water receiving portion 27. The guide portion 53a has a concave shape in cross section, but may have a V shape. The guide part 53a has a downward slope toward the front.

  In the front part of the guide part 53a, the flow path is bent outward and connected to the vertical flange part 53b. The vertical flange 53 b extends downward through a hole 57 formed in the flat portion 27 a on the other side in the longitudinal direction of the bottom plate 37. A fourth horizontal flange 55 is disposed below the vertical flange 53b.

  Refer to FIG. The fourth horizontal flange 55 is disposed along the other side of the lower frame 49. The rear end portion 55a of the fourth horizontal flange portion 55 is located below the vertical flange portion 53b. The fourth recumbent portion 55 has a downward slope toward the front. The front end 55b of the fourth horizontal flange 55 extends into the second tray accommodating portion 49b. As a result, when the second tray 15 is mounted in the second tray accommodating portion 49b, the front end 55b of the fourth horizontal flange portion 55 is located above the rear portion of the second tray 15. A water storage portion 15a for storing water flowing down from the recumbent portion 51 is provided on the front outer side portion of the second tray 15 (see FIG. 21), and the water falling from the front end 55b of the fourth recumbent portion 55 is the second It is accommodated in the tray 15.

A water receiver 27. The bottom wall 5e has a flange portion 25 extending downward from the rear edge portion of the bottom wall 5e. The water receiving portion 27 includes a flat portion 27a extending in the longitudinal direction of the rear wall 5d, parallel to the flange portion 25, and a groove 27b extending downward from the flat portion 27a and bent forward. The heating cooker 1 includes a coupling portion 29 that couples the flange portion 25, the lower portion of the rear wall 5 d of the heating chamber 5, the lower portion of the fan case 21, and the flat portion 27 a of the water receiving portion 27. The flat portion 27a of the water receiving portion 27 is coupled to 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 has one and the other in the longitudinal direction. Each of the grooves 27b is curved so that the end portion 27d on one side is located forward of the branch point 27c. From this configuration, the following effects can be obtained.

  Since the water receiving portion 27 is a separate member from the fan case 21, the degree of freedom of the shape of the water receiving portion 27 can be increased. Thereby, the process which curves the groove | channel 27b ahead can be made easy. Since the curved water receiving portion 27 is coupled to the fan case 21, alignment in the front-rear direction during assembly is facilitated. Further, even if the coupling portion 29 is a coupling with a gap such as caulking coupling, 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. Moreover, since the groove | channel 27b curves ahead, the water which falls from the edge part 27d of one side has the speed component of a front direction, Therefore The scattering of the water to a longitudinal direction can be reduced. Moreover, since the groove | channel 27b curves ahead, the other water receptacle which protruded also behind the groove | channel 27b can be arrange | positioned, and the scattering of the water to back can be reduced. Thereby, since the necessity for providing a structure for preventing scattering separately on the outside in the longitudinal direction is reduced, the cooking device 1 can be downsized in the longitudinal direction.

  Further, the branch point 27c of the water receiving portion 27 is located on the other side of the center of the groove 27b in the longitudinal direction. Thereby, the quantity of the water which flows into the groove | channel 27b of one side can be made larger than the other side. As a result, the capacity of the water storage portion 15 a of the second tray disposed 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 where the flow path is long is low. As a result, the end 27d of the groove 27b on the side with the longer flow path can be brought closer to the next water receiving part, so even if the amount of water flowing in the groove 27b is large, water can be smoothly flowed to the next water receiving part. Can do.

  The heating cooker 1 includes a water supply tank 14 that supplies water to the steam generator 16, and the water supply tank 14 is disposed on the other side of the heating cooker 1. Thereby, the water supply tank 14 is arrange | positioned ahead of the branch point 27c of the groove | channel 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 that houses the water supply tank 14 can be reduced. Thereby, since the capacity | capacitance of the water storage part 15a of the 2nd tray 15 can be made small, the capacity | capacitance of the water supply tank 14 is securable.

  The present disclosure is not limited to the above embodiment, and can be modified as follows. In the above-described embodiment, different flow paths are configured on one side and the other side in the longitudinal direction, but each configuration may be interchanged between the one side and the other side.

  In addition, it can be made to show the effect which each has by combining suitably any embodiment among the said various embodiment and modifications.

  Although the present disclosure has been fully described in connection with preferred embodiments with reference to the accompanying drawings, various variations and modifications will be apparent to those skilled in the art. Such changes and modifications are to be understood as included within the scope of the present disclosure as set forth in the appended claims. In addition, combinations of elements and changes in the order in each embodiment can be realized without departing from the scope and spirit of the present disclosure.

  The heating cooker according to the present disclosure is useful as, for example, a high-frequency heating cooker, a high-frequency heating cooker with a steam generator, or a heating cooker with a heater.
