In (a), FIG. 1 (b) and FIG. 1 (c), 4 is a casing and 5 is a motor. As in the conventional example of FIG. 4, the motor 5 is fixed to the upper part of the casing 4 with its output shaft facing downward, the output shaft of the motor 5 is inserted into the casing 4, and the blade is attached to the tip of the output shaft. The car is fixed. 1 and 2 are casings 4
A suction port and a delivery port that are provided to project. The roots of the inlet port 1 and the outlet port 2 are located at the corners between the side surface 4a and the bottom surface 4b of the casing 4, respectively, and the inlet port 1 and the outlet port 2 face a little diagonally downward at the root portion. , Both of their tips are facing sideways. In addition,
The casing 4 is formed by molding a synthetic resin mold,
The suction port section 1 and the delivery port section 2 are also constructed integrally with the casing 4. Reference numerals 6 and 7 are flanges provided at the tips of the suction port 1 and the delivery port 2, respectively. When the electric pump is actually installed, the end portions of the outer pipes are joined to the flange portions 6 and 7. FIG. 2 is a perspective view of the casing 4 when viewed from the bottom.

た事により破損の可能性は非常に小さい。Reference numeral 11 denotes a plate-shaped portion that is provided on the bottom surface of the casing 4, the suction port portion 1 and the delivery port portion 2. The plate-like portion 11 extends linearly from the foot portion 8 of the suction port portion 1 to the foot portion 9 of the delivery port portion 2 and is integrally projected from the bottom surface of the casing 4, the suction port portion 11 and the delivery port portion 2. There is. Thus, even if the electric pump receives a force between the suction port portion 1 and the delivery port portion 2 in a direction in which they are pressed against each other or in a direction in which they are separated from each other, the plate-shaped portion 11 is in between, that is, the suction port. It plays a role of a support between the portion 1 and the outlet portion 2, prevents the force from being concentrated on the root portions of the inlet portion 1 and the outlet portion 2, and relaxes the distortion of the casing 4. By providing the plate-like portion 11 in this manner, the casing 4 can sufficiently withstand a lateral force. Further, when a force is applied to the motor 5 from above, a force is also applied to the casing 4 from above, so that the suction port 1 and the delivery port 2 are pushed apart from each other. However, also in this case, the possibility of breakage is very small because the plate-shaped portion 11 is provided.

持つ事となる。Reference numeral 12 is a pillar portion formed in the central portion of the plate-shaped portion 11. The column portion 12 is made by disposing the resin injection port of the molding die for making the casing 4 at this position.
Then, the columnar portion 12 or the plate-shaped portion 11 has a further reinforcing effect.

ある。Advantageous Effects of Invention As described above, according to the present invention, the casing is arranged under the motor, and the casing, the suction port and the bottom face of the delivery port are linear from the foot of the suction port to the leg of the delivery port. Since the plate-like part extending to the casing integrally projects from the bottom of the casing, the suction port, and the delivery port, force is applied to the suction port and the delivery port from the external pipe in the direction toward and away from each other. Even if is added, it is possible to reduce the concentration of force on the roots of the suction port and the delivery port, by supporting the plate-shaped part as a support, and to prevent damage to the roots of the suction port and the delivery port. It is possible to prevent the distortion of the casing. In addition, even when a strong force is applied from above to generate a force that pushes the suction port part and the delivery port part apart from each other, the plate-like part acts as a reinforcement and can sufficiently withstand the force. It's done, and its practical effects are enormous.
