Description

Cooking device with steam generation function

The present invention relates to a cooking device with a steam generation function having a water tank receiving portion and the like.

¡The cooking device with steam generation function performs cooking that prevents dehydration of food and other heated objects. Moreover, the cooking device with a steam generation function performs cooking of steamed dishes.

A conventional cooking device with a steam generating function has, for example, a water tank for supplying water for generating steam on the side surface of the cooking device with a steam generating function, as disclosed in Patent Document 1. Moreover, the conventional cooking device with a steam generation function has the water tank for supplying the water for steam generation in the lower part of the cooking device with a steam generation function, for example as disclosed by patent document 2.

FIG. 9 is a perspective view showing a conventional cooking device with a steam generation function described in Patent Document 1. FIG. As shown in FIG. 9, the water tank 221 is arrange | positioned at the side surface of the heating cooker 204 with a steam generation function. The water supplied from the water tank 221 is heated in a steam generation unit (not shown) to become steam, which is used for cooking. The generated steam is then condensed on the heating chamber side of the door 201 provided on the front surface of the heating chamber. Condensed condensed water flows downward and enters the condensed water receiving portion 223 provided below the door 201.

However, since the heating cooker 204 with a steam generation function in which the water tank 221 is arranged on the side surface has the water tank 221 on the side surface, the width of the heating cooker 204 with the steam generation function is increased. Furthermore, the heating cooker 204 with a steam generation function in which the water tank 221 is arranged on the side surface requires a space for the water tank 221 to be taken in and out. That is, a space must be secured and installed on the side of the cooking device 204 with a steam generation function. By these, the space | interval of the width direction required in order to install the heating cooker 204 with the steam generation function which has arrange | positioned the water tank 221 to the side surface becomes large.

FIG. 10 is a perspective view showing a conventional cooking device with a steam generation function described in Patent Document 2. As shown in FIG. FIG. 11 is a partial view of a conventional cooking device with a steam generating function described in Patent Document 2 cut at a substantially front center. As shown in FIGS. 10 and 11, the water tank 121 is arranged at the lower part of the heating cooker 104 with a steam generating function. The bottom plate 127 supports the heating chamber 102 from the bottom surface. The water tank receiver 130 is provided in a space in front of the bottom plate 127 (left side in FIG. 11). The water tank receiving part 130 is a box shape whose front is opened. The water tank 121 is supported by the water tank receiver 130. The water tank 121 can be inserted and removed in the front-rear direction.

The dew condensation water receiving part 123 is arranged at the lower part of the heating cooker 104 with a steam generating function. As shown in the perspective view of FIG. 12, the dew condensation water receiving portion 123 has an opening 131 so that the water tank 121 can be inserted and removed. Further, the dew condensation water receiving portion 123 is locked by a stopper 128 fixed to the bottom plate 127, and is detachable forward as indicated by an arrow in FIG. The condensed water receiving portion 123 has an opening 131 and is locked only by the stopper 128 as shown in the partial view of FIG. In addition, FIG. 13 is the partial surface view which cut | disconnected the right end vicinity of the heating cooker 104 with a steam generation function toward the front. Therefore, with this state, the condensed water receiving portion 123 is liable to be inclined when being mounted. Therefore, the water tank receiver 130 supports the condensed water receiver 123 by the upper part 132 of the opening 131 as shown in FIG. Thereby, the inclination of the condensed water receiving part 123 is prevented. Thus, since it is necessary to support the dew condensation water receiving part 123 by the upper part, the water tank receiving part 130 is a box shape which opened the front surface.

Moreover, as shown in FIG. 11, the water supplied from the water tank 121 is sent to the steam generation unit 126 by the pump 125 and heated to become steam. The steam is sent to the heating chamber 102 and used for cooking the object to be heated. Here, the steam condenses on the heating chamber 102 side of the door 101 provided on the front surface of the heating chamber 102. The condensed water that has condensed forms a downward flow, falls from the gap between the door 101 and the heating chamber 102, and enters the condensed water receiver 123.

In this way, the heating cooker 104 with the steam generation function in which the water tank 121 is arranged at the lower portion requires a small space in the width direction for installation. However, the water tank receiving part 130 needs to be a box shape with the front surface opened. Moreover, the opening of the front surface needs to be larger than that of the water tank 121. That is, the water tank receiving portion 130 having this shape has a problem that it is difficult to manufacture by resin molding.

(Embodiment 1)
1 is a perspective view of a cooking device with a steam generating function according to Embodiment 1 of the present invention. FIG. 2 is a perspective view of the cooking device with a steam generating function in the present embodiment as seen from the front. The heating cooker 4 with a steam generating function cooks an object to be heated such as food in the heating chamber 2 by, for example, high-frequency heating. The heating cooker 4 with a steam generating function includes a high frequency generator (not shown) for outputting a high frequency to the inside of the heating chamber 2. The high frequency generator is installed on the bottom surface or side surface of the heating chamber 2.

The heating cooker 4 with a steam generating function has a box-shaped main body case 3 whose front is opened. The heating chamber 2 is formed inside the main body case 3. An object to be heated such as food is taken in and out from the opening on the front surface of the main body case 3. A door 1 is provided at the opening. The lower end of the door 1 is coupled to the lower edge portion 22 of the main body case 3 by a hinge mechanism. Thereby, the door 1 rotates in the up-down direction and opens and closes. The door 1 has a handle 15 at the top. As shown in FIG. 2, when the handle 15 is lowered, the door 1 opens.

The heating cooker 4 with a steam generating function supplies steam to the heating chamber 2. The water that is the source of steam is supplied from the water tank 21. The water tank 21 is arrange | positioned in the approximate center of the lower part of the heating cooker 4 with a steam generation function. The lid 32 is fitted with the water tank 21 to prevent water leakage. Condensed water receiving portions 23 are arranged on the left and right sides of the water tank 21 so as to sandwich the water tank 21.

The steam in the heating chamber 2 is condensed on the wall surface of the door 1 on the heating chamber 2 side during or after cooking. The condensed water that has condensed will flow downward. Moreover, the residual water which is the water | moisture content from the dew condensation water or the foodstuff may remain on the bottom face of the heating chamber 2. Condensed water and residual water flow downward as indicated by arrows in FIG. The lid | cover 32 and the dew condensation water receiving part 23 receive the dew condensation water and residual water which flowed below. Thereby, dew condensation water and residual water are prevented from falling to the floor.

Next, a configuration for supplying steam to the heating chamber 2 will be described with reference to FIG. FIG. 3 is a partial view of heating cooker 4 with a steam generating function according to the present embodiment, cut along line 3-3 in FIG. 7 to be described later. The water tank 21 is attached to a water tank receiving part 30 installed at the lower part of the heating cooker 4 with a steam generating function. The water tank 21 has a drain port 20a for supplying water to the outside.

When the water tank 21 is mounted on the water tank receiving part 30, the drain port 20a is communicated with the water supply port 20b connected to the pipe 19 for flowing water. A pump 25 is provided in the middle of the pipe 19. The water in the water tank 21 is sucked up by the pump 25 and sent to the steam generator 26. The steam generation unit 26 includes a sheathed heater and the like, and heats water. The water heated by the steam generation unit 26 is further supplied to the steam generation tray 29 inside the heating chamber 2 through the pipe 18. The steam generation tray 29 is arranged in contact with or close to the steam generation unit 26 via the bottom surface of the heating chamber 2. The water supplied to the steam generating tray 29 is further heated to become steam. The steam generated in this manner has a function of giving moisture to the dried object to be heated. The steam generated in this way is used for steamed dishes.

The steam in the heating chamber 2 condenses during or after cooking. Condensed condensed water flows downward through the door 1 and is received by the lid 32 and the condensed water receiving portion 23. In addition, the dew condensation water or residual water dew condensation on the bottom surface of the heating chamber 2 may flow forward when the door 1 is opened. That is, the condensed water and residual water that have flowed out are also received by the lid 32 and the condensed water receiver 23.

Here, the configuration of the lid 32 and the condensed water receiving part 23 will be described with reference to FIGS. FIG. 4 is a perspective view showing the water tank 21, the lid 32, and the dew condensation water receiving portion 23 of the cooking device 4 with the steam generating function of the present embodiment. The water tank 21 is attached to and supported by a water tank receiving portion 30 installed on the bottom plate 27. The lid 32 is installed in the water tank 21 by fitting. The lid 32 has a condensed water drainage channel 33 on the top surface. The condensed water drainage channel 33 receives condensed water or the like from the bottom surface of the door 1 or the heating chamber 2. On the periphery of the condensed water drainage channel 33, a water leakage prevention wall 34 is provided.

FIG. 5 is a cross-sectional view of the portion of the lid 32 where the condensed water drainage channel 33 is formed. The condensed water drainage channel 33 has a slope inclined downward from substantially the center toward both ends. Water injection ports 35 are provided at both ends of the condensed water drainage channel 33. The condensed water that has fallen on the condensed water drainage channel 33 flows downward on the slope of the condensed water drainage channel 33 and enters the condensed water receiving portion 23 from the water injection port 35. FIG. 6 is a cross-sectional view of a portion of the lid 32 where the condensed water drainage channel 33 is not formed. Water leakage is prevented by the water leakage prevention wall 34 to the portion where the condensed water drainage channel 33 is not formed.

FIG. 7 is a perspective view of the cooking device 4 with a steam generating function in the present embodiment as viewed from the bottom side. The water tank receiving part 30 is fixed to the bottom plate 27. The water tank 21 is attached to and supported by the water tank receiver 30.

Here, behind the condensed water receiving portion 23, locking projections 23a are formed on the left and right with the water tank 21 in between. Further, a C-shaped clip portion 23b is formed on the left and right rear sides of the dew condensation water receiving portion 23 and outside the locking projection portion 23a. The locking projection 23 a of the condensed water receiving portion 23 is fitted with a C-shaped locking portion 36 formed on the water tank receiving portion 30. Further, the clip portion 23 b of the condensed water receiving portion 23 is fitted with a stopper 28 fixed to the bottom plate 27. By means of the locking projection 23a and the locking portion 36, and the clip portion 23b and the stopper 28, the dew condensation water receiving portion 23 is locked to the heating cooker 4 with a steam generating function at the rear.

Therefore, the water tank receiving part 30 does not need to support the condensed water receiving part 23 at the upper part. As a result, the shape of the water tank receiving part 30 does not need to be a box shape with the front surface opened. That is, the shape of the water tank receiving part 30 can be reduced in size, and manufacturing such as resin molding becomes easy. Furthermore, by reducing the size of the water tank receiving portion 30, it is possible to save resources and stabilize the shape of the resin molding. Moreover, the dew condensation water receiving part 23 can be attached or detached independently from the heating cooker 4 with a steam generation function regardless of the presence or absence of the water tank 21. The stopper 28 can also be used as a leg portion of the heating cooker 4 with a steam generating function.

Here, a configuration for supporting the water tank 21 and the water tank receiving portion 30 will be described with reference to FIG. FIG. 8 is a cross-sectional view showing the water tank 21 and the water tank receiving portion of the cooking device 4 with a steam generating function of the present embodiment. The water tank receiving portions 30 are installed on the left and right of the space where the water tank 21 is mounted on the bottom plate 27. The water tank receiving part 30 has a convex rail 30a on the inner side facing left and right. The water tank 21 has a concave groove 21a that receives the rail 30a at a position facing the rail 30a when mounted. The water tank 21 is supported by the water tank receiver 30 by the groove 21 a of the water tank 21 entering the rail 30 a of the water tank receiver 30. In addition, even if a concave groove is provided on the water tank receiving portion 30 side and a convex rail is provided on the water tank 21 side, the same can be implemented. Furthermore, it can implement similarly by providing a convex rail on both the water tank receiving part 30 side and the water tank 21 side, and placing the rail on the water tank 21 side on the rail on the water tank receiving part 30 side.

This increases the stability when the water tank 21 is inserted into the water tank receiver 30. Further, the position when the water tank 21 is inserted into the water tank receiving portion 30 is regulated. Thereby, communication with the drain 20a of the water tank 21 and the water supply port 20b is performed reliably.

The heating cooker with a steam generating function of the present invention can be used for a heating cooker having a water tank because the structure for receiving the water tank is small.
