BACKGROUND OF THE INVENTION
The present invention relates to a built-in type microwave oven used in combination with other cooking devices such as an induction heating cooker and a gas range, and more particularly to a built-in type microwave oven using a kangaroo pocket type control unit.
[0002]
[Prior art]
Conventionally, a built-in type microwave oven used in combination with an induction heating cooker, a gas range, or the like using a kangaroo pocket type control unit is known (see, for example, Patent Document 1).
[0003]

[Patent Document 2]
Special table 2003-517564 gazette
FIG. 8 is a perspective view of an example of a built-in type conventional device described in Patent Document 1. In FIG. In the figure, 80 is a built-in type conventional apparatus, 81 is a gas cooker, 82 is a microwave oven, and 83 is a support base. The gas cooker 81 includes a gas range 81a and a grill part 81b.
The microwave oven 82 includes an exhaust port 81a, an open / close door 82b, and a kangaroo pocket type control unit (control panel) 82c. Since the microwave oven 82 is provided directly below the gas cooker 81, the air that has cooled the microwave oven cannot be exhausted directly from the ceiling of the microwave oven as in the case of a single microwave oven. In addition, since other system kitchen equipment is installed, it is not possible to exhaust from the side, and there is a wall near the rear, so if hot air is exhausted, hot air is trapped and adversely affects the cooling effect, so I can't even exhaust. As a result, the air that has cooled the microwave oven is exhausted upward through the casing of the gas cooker, or is exhausted from the front exhaust port 82a as shown.
[0004]
A kangaroo pocket is equipped with a display / operation unit on one side of the polyhedron and is not mounted on the other side, but is stored in the cover so that it can rotate around its axis, and is not installed when not in use. The surface is exposed from the cover, and when used, the polyhedron is rotated to expose the mounting surface of the display unit and operation unit to control the display unit and operation unit, improving operability and malfunction due to erroneous contact Can be prevented.
This kangaroo pocket type control unit 82c is provided on the side of the door in the conventional apparatus. If it is provided above the door, hot water vapor discharged from the heating chamber when the open / close door 82b of the microwave oven is opened hits the liquid crystal display part of the kangaroo pocket type control part, and the liquid crystal display part is fogged, or the water vapor is kangaroo pocket This is because it enters into the expression control unit and causes a failure of the electronic component, and this is avoided.
[0005]
In addition, in a microwave oven built in the system kitchen, the height of the support base 83 is determined to be a predetermined height along with other equipment in the system kitchen, so it cannot be lowered so much. The heating chamber of the microwave oven is lowered by the thickness 82a, and the width of the heating chamber is narrowed by the controller 82c. Thus, the built-in type conventional apparatus has a narrow heating chamber of the microwave oven in the vertical and horizontal directions.
Furthermore, since the controller 82c is also beside the door, it is difficult to operate because it is crouched during operation (operability is not good).
[0006]
On the other hand, a built-in type microwave oven in which a control panel (control unit) is provided above the heating chamber in order to improve operability is also known (see, for example, Patent Document 2). However, this is not a kangaroo pocket control unit.
[0007]
FIG. 9 is a perspective view of a main part of a built-in type microwave oven described in Patent Document 2. FIG.
In the figure, 90 is a built-in type microwave oven described in Patent Document 1, 91 is a front surface of the microwave oven, 92 is a control panel, 93 is a suction grille, and 94 is an exhaust grille. The microwave oven 90 has a control panel 92 at the top of the front surface 91, and a suction grill 93 and an exhaust grill 94 are provided directly below the control panel 92 so that cooling air can enter and exit from the front surface 91. The upper and lower heaters are provided, the upper heater passage is provided with an upper internal passage through which the air flow from the upper heater cooling fan passes, and the lower heater cooling fan is provided with the lower heater portion. A cooling passage through which the air flow is passed is provided, and a part of the air sucked from the suction grill 93 is directly supplied to the front of the exhaust grill 94 and merges with the air heated by passing through the heater, and then exhausted. It is designed to be exhausted from the grill.
[0008]
As a result, the temperature of the air coming out of the exhaust grill 94 can be lowered, and the operability is improved because the control panel 92 is located above.
However, since the exhaust grill 94 is provided at the lower side, dust on the floor is blown up, resulting in a sanitary problem.
Moreover, since the suction grille 93 and the exhaust grille 94 occupy the upper and lower sides of the front surface, the height of the device itself is increased, and since it is a built-in type, it is not possible to increase the size of the microwave oven. The internal volume of the heating chamber was small.
[0009]
[Problems to be solved by the invention]
The present invention was made to solve such a problem, and it is not necessary to reduce the size of the microwave oven itself by adopting a configuration in which the exhaust grill is devised and the height is not increased. The purpose of the present invention is to provide a built-in type microwave oven that is hygienic, has a user-friendly controller, and does not become cloudy even if steam is emitted when the door is opened.

[0018]
2 to 5 show a kangaroo pocket type control unit according to the present invention.
2 is a perspective view of the kangaroo pocket type control unit 40 as viewed from the back, FIG. 3 is a perspective view of the case of FIG. FIG. 5 is a partial cross-sectional view, (a) when not in use, (b) during rotation, (c) when in use, FIG. 5 is a front view of the kangaroo pocket type control unit 40, and (a) in use , (B) respectively show the non-use time.
[0019]
In FIG. 2, reference numeral 40 denotes a kangaroo pocket type control unit according to the present invention, and the kangaroo pocket type control unit 40 can be constituted by a casing such as a triangular column, a quadrangular column, or a five-column column having a hollow inside. Here, a quadrangular prism composed of surfaces 42, 44, 48 and 48 is used, 42 is a display / operation surface, 44 is a non-use exposed surface (non-mounting surface), 46 is an exhaust surface, and 48 is an intake surface. The exhaust surface 46 is provided with a plurality of openings 46a for exhausting cooling air according to the present invention, and the intake surface 48 is provided with a plurality of openings 48a for intake of cooling air in the length direction. Both ends (left and right ends in the figure) of the quadrangular column are closed with side plates 43, and pin insertion holes 43a are opened at the center of rotation. The pin P can be rotated by inserting the pin P into the pin insertion hole 43a together with the pin insertion holes 223a formed at both ends of the control unit storage chamber 22 (FIG. 7) fixed to the microwave main body 20.
[0020]
On the display / operation surface 42 of the kangaroo pocket type control unit 40, in addition to the liquid crystal display unit 421 (FIG. 5) indicating the control content, heating temperature, elapsed heating time, etc., a start switch for instructing the start of heating, high-frequency heating Various operation switches 422 (FIG. 5) such as a changeover switch for switching between other heating methods and an automatic cooking switch for starting a heating program prepared in advance are mounted.
[0021]
A control board for controlling the liquid crystal display unit 421 and the operation switch 422 is mounted inside the housing. FIG. 3 illustrates this control board 49.
The control board 49 is a printed circuit board on which an electric component for controlling and displaying a microwave oven, a CPU, and the like are mounted, and a large number of components that generate heat are mounted on the printed circuit board 49 and need to be cooled.
[0022]
In FIG. 4, the control unit storage chamber 22 is a U-shaped housing composed of an upper surface 221, a rear surface 222, and a lower surface 223, with the open surface facing the user and the rear surface 222 fixed to the microwave housing. is doing. The back surface 222 is provided with a number of openings 222a in the length direction (FIG. 6). Further, a control portion receiving projection 22a is provided on the control portion storage chamber 22 side.
[0023]
To rotate the kangaroo pocket type control unit 40 so that it is not in use, for example, a small knob is provided in the operation part of the kangaroo pocket type control unit 40, and the pin P is centered by pulling it. What is necessary is just to make it return to an accommodation state by making an operation part pop out and returning it. Alternatively, a push button for pop-out operation and a push button for storage operation are provided on the microwave oven casing 20 side, and the pop-up state is established by pressing the former button, and the button is returned by pressing the latter button. You may do it.
[0024]
When not in use in FIG. 4A, the intake surface 48 is stabilized in a state of leaning against the control portion receiving projection 22a. In this state, the non-use exposed surface 44 of the kangaroo pocket type control unit 40 is in tricature with the front surface of the control unit storage chamber 22. Therefore, the display / operation surface 42 is hidden inside the control unit storage chamber 22, and the control switch or the like does not operate due to erroneous contact or the like (see also FIG. 5B).
Even if the microwave oven has been used, the cooling fan may continue to rotate for a predetermined time. Even in this case, the cooling air enters from the rear surface opening 222a, proceeds through the intake surface opening 48a in the direction indicated by the arrow, and is controlled. Since the substrate 49 is cooled and flows from the exhaust surface opening 46a to the outside through the gap A between the kangaroo pocket type control unit 40 and the lower surface 223 of the control unit storage chamber 22, the control substrate 49 can be continuously cooled.
[0025]
In FIG. 4B, the kangaroo pocket type control unit 40 is rotating around the pin insertion hole 43 a inside the control unit storage chamber 22. When not in use, the exposed surface 44 begins to hide and the display / operation surface 42 begins to be exposed, or vice versa.
Also in this case, the cooling air can flow to the outside through the gap between the kangaroo pocket type control unit 40 and the lower surface 223 of the control unit storage chamber 22 in the direction indicated by the arrow. Continue to cool the substrate 49.
[0026]
During the use of FIG. 4C, the intake surface tip 43 is stable in a state where it leans against the tip flange 221 a of the upper surface 221 of the control unit storage chamber 22. In this state, the display / operation surface 42 of the kangaroo pocket type control unit 40 is in a supine state (about 45 degrees in the figure), which makes it easier to operate than the vertical control unit (FIG. 9).
Since the cooling fan continues to rotate while the microwave oven is in use, the cooling air enters from the rear surface opening 222a, proceeds in the direction indicated by the arrow through the intake surface opening 48a, cools the control board 49, and from the exhaust surface opening 46a. Since it flows outside through the gap A between the kangaroo pocket type control unit 40 and the lower surface 223 of the control unit storage chamber 22, the control board 49 can be cooled.
[0027]
As described above, the cooled air is discharged through the gap A between the kangaroo pocket type control unit 20 and the control unit storage chamber 22, so that the air between the kangaroo pocket type control unit 20 and the opening / closing door 30 of the microwave oven 20 is discharged. A curtain has occurred. Therefore, even when the opening / closing door 30 of the microwave oven 20 is opened during use and hot water vapor is raised from the heating chamber 23, the water curtain does not approach the kangaroo pocket type control unit 40 due to the air curtain, and hits the liquid crystal display unit and the liquid crystal. No clouding of the display part occurs, and no water vapor enters the kangaroo pocket type control unit 40 and causes the electronic components to fail.
[0028]
5A, since the display / operation surface 42 of the kangaroo pocket type control unit 40 is in a supine state (about 45 degrees in the figure), the liquid crystal display unit 421 is easy to see and the operation switch 422 is easy to operate. Further, the cooling air flows out through a gap between the kangaroo pocket type control unit 40 and the lower surface of the control unit storage chamber 22 to form an air curtain.
[0029]
When not in use in FIG. 5B, the display / operation surface 42 is hidden, and the non-mounting surface 44 on which nothing is mounted is exposed instead. Therefore, the control switch or the like does not operate due to erroneous contact or the like. As long as the cooling fan is rotating, the cooling air flows out through the gap between the kangaroo pocket type control unit 40 and the lower surface of the control unit storage chamber 22 to form an air curtain.
[0030]
FIG. 6 is a perspective view of the microwave oven to which the kangaroo pocket control unit 40 of FIG. In the figure, reference numeral 10 denotes a microwave oven, which is largely composed of a microwave oven casing 20 and an opening / closing door 30. The microwave oven case 20 has an intake fan 201 for taking air into the microwave oven case 20 below the back plate 206, a cover 202 that covers the intake fan 201, and the air inside the cover 202 is removed from the housing 20. And a guide plate 203 to be sent upward. The cover 202 opens downward, and when the intake fan 201 rotates, cold air is sucked from the opening, enters the cover 202, passes through the guide plate 203, and is sent above the housing 20. An opening 206a (FIG. 1) is provided in a portion of the back plate 206 of the housing 20 that contacts the guide plate 203, and the air that has reached the top enters the back of the ceiling of the housing 20 through the opening 206a.
[0031]
On the back of the ceiling, a partition plate 204 (FIG. 6) is placed in parallel with a predetermined distance from the side surface of the housing 20, and in contact with the partition plate 204, it is partitioned in parallel with the kangaroo pocket type control unit 40. A plate 205 is provided.
These partition plates 204 and 205 prevent the outer periphery of the heating chamber, which is another cooling system, from being cooled and mixed with hot air discharged from the discharge port 28 (FIG. 1) to the ceiling back discharge space 209. Therefore, the cooled air discharged from the gap under the kangaroo pocket type control unit 40 does not become hot (90 degrees or more), and there is no possibility of burning the user. In addition, the hot air which cooled the outer periphery of the heating chamber which is another cooling system, and was discharged from the discharge outlet 28 (FIG. 1) to the ceiling back discharge space 209 is further pulled upwards, rises, and is a housing | casing of an electromagnetic cooker. It is exhausted upward from the rear corner through the rear.
[0032]
Through the air passage 207 formed between the side wall of the housing 20 and the partition plate, the air moves forward of the housing 20, passes through the air passage between the control portion storage chamber 22 and the partition plate 205, and the control portion storage chamber 22. Enters the back side of the kangaroo pocket type control unit 40 through the opening 222a provided in the kangaroo pocket. The subsequent air is discharged to the outside through the gap of the kangaroo pocket type control unit 40 through the path described in FIG. The air curtain effect functions when discharged from the gap, and prevents entry of steam or the like into the kangaroo pocket type control unit 40.
[0033]
FIG. 7 is a perspective view of the microwave oven of FIG. 6 as viewed from the front side, and shows a state in which the kangaroo pocket type control unit 40 is removed. Cold air from the lower back of the microwave oven case enters the ceiling of the housing 20 through the opening 206a provided at the upper corner of the back plate 206 as described with reference to FIG. It can be seen that the kangaroo pocket type control unit 40 enters the kangaroo pocket type control unit 40 from the opening 222a of the unit storage chamber 22 and is discharged to the outside through the route described in FIG.
[0034]
As described above, the control board 49 is built in the housing of the kangaroo pocket type control unit 20, and a large number of electric / electronic components that generate heat are mounted on the control board 49. is there. Therefore, as described with reference to FIG. 6, cold air is sucked from the back surface of the microwave oven case 20 (FIG. 1), led to the air passage 207 through the opening 206 a provided in the back plate 206, and from there, the kangaroo pocket type control unit 20. After entering the inside through the opening 48a (FIG. 2) of the air intake surface 48 and cooling the control board 49 (FIG. 3), the kangaroo pocket-type control unit 20 passes through the opening 46a (FIG. 2) of the exhaust surface 46. The air is exhausted outside the housing, and discharged to the front surface of the microwave oven housing 20 through the gap A between the kangaroo pocket type control unit 20 and the control unit storage chamber 22.
[0035]
Therefore, when the open / close door is opened, hot water vapor is emitted from the heating chamber 23. However, the water vapor is generated in the air curtain by the flow of air discharged through the gap A between the kangaroo pocket type control unit 20 and the control unit storage chamber 22. The liquid crystal display unit is not clouded by hitting the liquid crystal display unit without being brought close to the expression control unit 40. Similarly, the entry of water vapor into the kangaroo pocket control unit 40 is also prevented, and the electronic components are not damaged.
[0036]
In addition, since the operation unit is placed on the upper part of the device, it can be operated without squatting, and since it has a kangaroo pocket, the control surface is not vertical but has a predetermined angle. The operability is remarkably improved as compared with the operation portion 9.
[0037]
Kangaroo pockets were originally not suitable for placing on top of the heating chamber. This is because the kangaroo pocket needs a gap to be able to rotate, and this gap became an obstacle during the development experiment. This is because, for example, vapor enters the inside of the kangaroo pocket from the gap, causing the liquid crystal display to be fogged, and heating or moistening the electric parts.
[0038]
Therefore, in order to prevent the intrusion of steam, the applicant of the present invention tried to install a cushion in the gap, but this required extra cushions and increased man-hours for mounting, and the cost increased. As a result of the deterioration of the aging, the invasion of steam has occurred, and the operability (smooth rotation) of the kangaroo pocket has deteriorated.
[0039]
Therefore, the present applicant has noticed that all of these drawbacks can be eliminated by positively using the gap, which is a disadvantage of providing the kangaroo pocket above the opening and closing door, as the air curtain outlet. By actively using the gap of the kangaroo pocket as an air curtain outlet in this way, there is no need to use a cushion, the cost is low, the invasion of steam is eliminated by the air curtain effect, and operability is improved. In addition, since the original exhaust port (93 in FIG. 9) was substituted, this became unnecessary and the space for the exhaust port could be omitted.
[0040]
Thus, according to the microwave oven 10 according to the present invention, since the kangaroo pocket type control unit 40 is attached to the upper front portion of the apparatus, it is not necessary to squat each time the operation button is operated, and the operability is improved. In addition, since air is exhausted from the opening clearance of the kangaroo pocket type control unit 40, there is no need to provide a separate exhaust port, so that the space in the heating chamber is large and exhaust is performed at the upper part of the front surface of the apparatus. It won't roll up and will be clean.
[0041]

Since it is exhausted from the clearance for the operation, it is not necessary to squat each time the operation unit is operated, and operability is improved, and air is exhausted from the opening clearance of the kangaroo pocket type control part, so an exhaust port is separately provided Since it is not necessary to provide the device, the device is not bulky and an air curtain is formed, so that the liquid crystal display of the kangaroo pocket type control unit does not become cloudy.
[0042]
According to invention of Claim 2, since the ventilation part was provided in the back side of the microwave oven, since the inlet port and the exhaust port isolate | separated on the back surface and the front surface on both sides of the apparatus, it came out from the exhaust port, and warm Cooling efficiency is improved without inhaling air.
[0043]
According to the third aspect of the present invention, the air from the blower unit is guided to the back of the ceiling of the heating chamber and from there to the back surface of the kangaroo pocket type control unit, so that the ceiling of the microwave oven is cooled. .
[0044]
According to the fourth aspect of the present invention, the guide member is provided on the back side of the back plate of the microwave oven and guides the air from the air blowing unit to the corner of the back of the ceiling, and is provided on the back side of the ceiling.
