Is forming.

  In the arrow view seen from the bottom of FIG. 2, the bottom handle C110 formed one each on the left and right of the substantially central portion in the front-rear direction of the lower base plate is formed of the substantially rectangular lower base plate 41 having an opening 43 in the center. The front and rear beams 47 that connect the front side of the housing 44 and the rear side of the back plate 45 are positioned substantially at the center, and are integrally formed in a rectangular box shape having an opening 111 below. It is designed to be insertable.

  FIG. 3 shows a side view of the drum-type washing machine according to the embodiment of the present invention in a state where the drum-type washing machine is lifted at the time of transportation on an inclined floor surface 48 having a height difference of K dimension between the front and rear workers. In FIG. 3, the worker B107 located at a low position puts his hand on the bottom handle C110 on the lower surface of the substantially central portion of the lower base plate 41 and lifts it up when carrying an inclined floor such as stairs.

  Therefore, when the conventional front handle B105 is lifted, the drum-type washing machine 1 is lifted high by a size corresponding to the height G, and the inclination angle E of the housing 44 from the horizontal plane is the front handle. The position of the lowest point P of the drum-type washing machine is to maintain a marginal gap dimension F with respect to the floor surface 48 such as a staircase because it approaches the horizontal from the angle N when the part B105 is lifted (conventional example Fig. 7). Can do.

  FIG. 4 is a longitudinal sectional view of the drum type washing machine in the embodiment of the present invention.

  In FIG. 4, the water tank 3 that rotatably supports and includes the rotary drum 2 is supported by an upper spring body 71 above the housing 44 and swingably by a lower spring body 72 at the rear of the housing 44. During the dehydration operation, vibrations when the clothes put into the rotary drum 2 are dehydrated are absorbed. Further, in order to prevent the vibration of the water tank 3 from shifting to abnormal vibration such as resonance, vibration isolating dampers 70 are disposed on the left and right below the water tank 3 and disposed between the water tank 3 and the lower base plate 41 to attenuate the vibration of the water tank 3. To support.

  Since the movement of the water tank 3 is forcibly damped, a large load is applied to the lower base plate 41 via the vibration-proof damper 70. Therefore, this portion has a structure having the following strength.

  That is, the anti-vibration damper 70 is fixed to a water tank support plate 49 such as a steel plate whose upper part is fixed to the bottom of the water tank 3 with an upper bolt 50, and the lower part is a base reinforcing plate 51 made of a steel plate fixed to the lower base plate 41. The water tank is fixed by a lower bolt 52, and is oscillated in the front-rear and left-right directions by an oil damper (not shown) inside the vibration-proof damper 70 and a coil spring 73 so that the vibration of the water tank 3 does not resonate. Attenuating effect while following.

  On the other hand, the bottom handle C110 formed on the lower base plate 41 on the left and right sides is formed in the vicinity of the mounting portion of the lower bolt 52, which is the lower mounting configuration of the anti-vibration damper 70.

  Furthermore, the base reinforcement board 51 comprised with the steel plate is arrange | positioned so that the upper surface of the bottom face handle part C110 may be covered.

  About the washing machine comprised as mentioned above, the operation | movement and an effect | action are demonstrated.

  First, in the drum type washing machine 1, the bottom base plate 41 at the bottom of the housing 44 is provided with a bottom handle C110 on the lower surface of the substantially central portion in addition to the handle B105 in the conventional example. .

  In the case of inclined floor transportation, one worker A106 puts both hands on the handle portion A101 provided on the upper left and right of the back of the casing 44 of the drum type washing machine, and the other worker B107 The bottom handle C110 is put on the lower surface of the central portion and lifted.

  Accordingly, the lowermost point P of the drum-type washing machine 1 is lifted as compared with the case where the handle B105 in front of the lower base plate 41 is handed over as in the prior art. Since a certain stable work can be performed, it is excellent in safety and workability.

  When the worker B107 lifts the bottom handle C110 on the lower surface of the substantially central portion, the center of gravity of the drum type washing machine is not positioned at the middle point between the two workers, and the handle B107 is held near the center. However, this work is performed on an inclined surface such as a staircase, and the center of gravity can be increased by returning to the conventional work on the front handle B105 on a smooth floor surface with a distance. Since it is located approximately in the middle between the two workers A106 and B107, it can be used properly such that the weight can be shared almost equally.

  In addition, the vibration damping damper 70 disposed between the water tank 3 and the lower base plate 41 for damping and supporting the vibration of the water tank 3 is a portion where the lower base plate 41 is provided with strength. The position of the bottom handle C is arranged in the vicinity of the attachment portion of the vibration-proof damper to the lower base plate.

  Accordingly, the bottom handle C has a structure having strength, and can secure safety during transportation of a heavy drum type washing machine.

  Further, a base reinforcing plate 51 made of a steel plate is provided in the lower bolt 52 mounting portion to the lower base plate 41 of the vibration isolating damper, but the bottom handle portion C is positioned at the base reinforcing position. Since the plate 51 is constructed so as to cover the upper surface, the strength of the bottom handle C is remarkably increased, and the bottom handle C is damaged by the weight of the washing machine body while carrying the bottom handle C during transportation. It becomes difficult and the safety at the time of transportation is secured more.

  Since the drum type washing machine of the present invention can improve safety and workability when carrying a heavy casing, it is useful for equipment that requires a heavy casing.
