Port A Cool Fan

This would account for the great difficulty in cooling the high frequency power supply unit 3 and the magnetron 2. The high frequency power supply means includes a power control semiconductor device and a high-voltage transformer which are disposed in the cooling air flow, in this order, along the direction of revolution of the propeller fan. Further, the motor is protected by overlapping a motor cover, which also serves as part of a motor support member, and a boss of an impeller with each other in a double structure above the fan motor. Besides with respect to the high-voltage transformer 25, when the coil 24 to be cooled is opposed and the propeller fan 13 to brought into contact with the air flow, the cooling effect is further enhanced. Therefore, cooling air can be suppressed from leaking through the clearance between the first guide wall 16 and the magnetron 11, which allows the spinning stream of the air flowing along the first guide wall 16 to be partially fed into the cooling path 52 of the magnetron 11, facilitating the cooling of the magnetron 11. Although the present invention has been fully described by way of example with reference to the accompanying drawings, it is to be noted here that various changes and modifications will be apparent to those skilled in the art.

As a consequence, the microwave heating device can be operated in intermittent use with less rest time.

Besides, since the first guide wall 16 and the second guide wall 46 are assembled in proximity to each other, air leakage through a clearance 48 between the first guide wall 16 and the second guide wall 46 can be prevented, which allows a large amount of cooling air to be applied to the parts to be cooled, and which allows shielding the radiation of the heat from side wall 19 of the heating chamber 10 with the first and second guide walls, where the heat radiation may interrupt the cooling of the parts. of the fan motor, and as a result, the noise generated from the air flow can be reduced.

Thus, it has been difficult to achieve an efficient cooling performance of the parts. SUMMARY OF THE INVENTION In order to solve ann author b ross the problems mentioned above, the present invention has been developed, having an essential objective of providing a microwave heating device which comprises a heating chamber in which an object or material be heated is heated by the application of microwave energy a microwave radiating means for radiating microwave energy to the object material to be heated, a high frequency power supply means for supplying high frequency electric power to the microwave radiating means, the high frequency power supply means being positioned in proximity to as well as in parallel to the microwave radiating means and perpendicular to a surrounding side wall of the heating chamber, an air feeding means installed in the lowermost portion of a mechanical chamber for feeding cooling air, which forms a cooling air flow from the lower part through an air suction port formed in a bottom wall of the mechanical chamber to cool the microwave radiating means and high frequency power supply means, and a control means for controlling book gift morning star the high frequency power supply means and air feeding means.

The same is true for athletes in training, construction work, and numerous other outdoor jobs. As a result, the parts can be cooled with high efficiency. 11, the propeller fan is controlled in such a manner that it is operated at a specified r. 10 is a perspective view of a state in which the bent portion of the frame of the same device is fixed at the connecting portion thereof; FIG. Description of the Prior Art There is known a conventional microwave heating device is disclosed, for example, in Japanese Patent Laid-Open Unexamined Publication No.

The microwave heating device of claim 3, wherein said control comprises means for driving said propeller fan at a first specified number of rotations per minute during an operation of said high frequency power supply and said magnetron and, after the operation of said high frequency power supply and said magnetron has stopped, driving said propeller fan for a specified period of time at a second specified number of rotations per minute lower than said first specified number of rotations per minute. 55RBearing support for microwave oven antenna4623771November, 1986Sakino219/10. Now, the following describes the assembling of these parts of the microwave heating device with reference to FIGS.
By this arrangement the cooling air path can be compacted so that the parts can be cooled with high efficiency.

Further, the noise due to air flow is radiated primarily to the outside of the housing 28 through the suction port 15, and since the noise due to air flow is radiated to the kitchen through a narrow space 33 defined by a housing bottom plate 31 and a base 32, the noise is largely decreased, so that the device can be even lower in noise generation.
)Next Patent (Image storing method. portion and fixed in an approximate L shape, and wherein said first and second guide walls define an airflow path for the cooling air flow for cooling said high frequency power supply; and at least one communicating hole in said first frame in proximity to said connecting portion for generating an air flow circulating therethrough for cooling parts of said high frequency power supply disposed in proximity to said connecting portion.

Since the installation work of the motor bibliography format mla format 20 and the impeller 27, which constitute the propeller fan 13, and the high frequency power supply unit 12, is carried out while the first frame 43 and the second frame 44 are both opened as shown in FIG. Since the air flow in proximity to an impeller 27 of the propeller fan 13 spins in the direction of revolution of the impeller 27, the parts to be cooled are disposed in order from the power transistor 23 to the high-voltage transformer 25 along the direction of the revolution of the impeller, i.

The heating device is further provided with a vent hole 7 formed in its bottom against all odss lyrics face 6, so that the propeller fan 4 sucks cooling air through the vent abc supply co. inc hole 7 to cool the magnetron 2 and the high frequency power supply unit 3. More Info PAC2K36AD Port-A-Cool Evaporative Portable Evaporative Coolers36" Single Speed Pneumatic Drive The Port-A-Cool PAC2K24AD is an effective, portable evaporative cooling system for special applications where high-volume air flow or ducting is needed. By this arrangement, even if metal chips and the like have dropped, which are possibly generated in tightening screws 36 (shown in FIG. 55E, 219/757, 126/21A, art clip ground hog 361/384 4100463July, 1978Sugie219/10.

By this arrangement, the motor, when used in the vertical direction, can be prevented from damage due to anything dropping from above. By this arrangement, in an airflow path 50 defined by the casing 17 of the propeller fan 13, which forms the first frame 43 and by the second frame 44, there arises an air flow that circulates through the communicating hole 49 (as indicated by the arrow in FIG.
