Detailed Description

In order to better understand the purpose, structure and function of the present invention, a bottom case and an air conditioner of the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, the bottom case of the present invention includes a case 1. An inner cavity 11 is arranged in the shell 1, and a rotatable through-flow fan blade 4 is arranged in the inner cavity 11. One end of the cross-flow fan blade 4 is provided with a bearing 2, and the other end is provided with a motor 3, so that the motor 3 drives the cross-flow fan blade 4 to rotate. An installation groove 12 is formed at one end of the inner cavity 11, and the installation groove 12 is used for installing the motor 3. The evaporator 5 is installed on the radial upper sides of the inner cavity 11 and the installation groove 12, so that airflow is generated through the cross-flow fan blade 4, heat exchange is performed between the evaporator 5 and indoor air, and cooling or heating is achieved.

And because mounting groove 12 direct forming is on casing 1, current motor 3 clamp plate and casing 1 integrated into one piece promptly, need not to install motor 3 clamp plate, and adopts the mode of inserting fixed mounting, specifically says:

as shown in fig. 3 and 4, an opening 121 is formed at an end of the mounting groove 12 away from the housing 1, and the opening 121 allows the motor 3 to be inserted into the mounting groove 12. Correspondingly, a through hole 122 is formed in the mounting groove 12 near one end of the housing 1, and the through hole 122 allows an output shaft of the motor 3 to be inserted into the inner cavity 11 of the housing 1 to drive the cross-flow fan blade 4 to rotate.

And the inner wall of the mounting groove 12 is provided with a fixing part which fixes the motor 3 in the mounting groove 12.

Specifically speaking:

the fixed part is formed with locating piece 31 including seting up constant head tank 13 on the mounting groove 12 inner wall, motor 3 lateral wall, and locating piece 31 inserts mounting groove 12 to carry out preliminary fixed to motor 3. Generally, the positioning slot 13 is a trapezoid structure, and a socket is formed at one end of the mounting groove 12 for inserting the positioning block 31. The aperture of the positioning groove 13 gradually increases along with the distance from the motor 3, and the positioning block 31 is trapezoidal and is attached to the positioning groove 13. Thereby preventing the motor 3 from shaking in the positioning groove 13.

In addition, the fixing part includes a screw post 14 provided on an inner wall of the mounting groove 12, an ear plate 32 is formed at a side of the motor 3, and the ear plate 32 is screw-coupled with the screw post 14, thereby fixing the motor 3 in the mounting groove 12. In order to ensure the strength of the ear plate 32, reinforcing ribs are formed on both sides of the ear plate 32.

Also, since the side end of the evaporator 5 is located at the upper side of the mounting groove 12, condensed water generated from the evaporator 5 easily flows into the mounting groove 12, causing a safety problem of the motor 3. In order to solve the above problem, baffles 15 are formed on the upper outer wall of the mounting groove 12 to face each other, and a water tank is formed between the baffles 15 to receive the condensed water generated from the evaporator 5. A drip tray 16 is attached to the underside of the sink to prevent water from entering the motor 3.

A heat radiating hole 123 is formed on the outer wall of the lower side of the mounting groove 12 to radiate heat of the motor 3. Generally, four heat dissipation holes 123 are uniformly formed to enhance the heat dissipation effect.

As shown in fig. 5 and 6, a relief space 6 is formed between the evaporator 5 and the adjacent baffle 15 to prevent the evaporator 5 from colliding against the bottom case. And the side plate of the evaporator 5 is in staggered fit with the bottom shell baffle 15, so that the sealing effect is achieved.

As shown in fig. 7 and 8, in particular, a positioning hook 51 is formed at one end of the evaporator 5 close to the mounting groove 12, a positioning hook 17 is formed on the housing 1, and the positioning hook 51 is hooked by the positioning hook 17 for fixing.

As shown in fig. 9 and 10, a positioning plate 52 is formed at one end of the evaporator 5 away from the mounting groove 12, and a protruding latch plate 521 is formed on the positioning plate 52; the housing 1 is formed with a coupling plate 18 to be attached to the positioning plate 52, and the coupling plate 18 is formed with a positioning hole 181 into which the latch plate 521 is inserted. Thereby preliminarily fixing the evaporator 5 on the case 1 by hooking and inserting. And the side plate of the evaporator 5 is provided with a flange which is screwed with both ends of the housing 1 to completely fix the evaporator 5 and form a relief space 6 at one side.

In conclusion, the shell 1 of the utility model has a simple and reliable structure, breaks through the traditional motor 3 installation mode through an integrated design, provides that the motor 3 is installed along the horizontal direction from the right side, is fixed by three screws, does not need to use the motor 3 pressing plate to fix the motor 3, can reduce two parts of an elbow sheath and the motor 3 pressing plate, reduces 1 fixing screw of the motor 3, can save a large amount of die sinking cost, material cost and labor cost, simultaneously reduces the air conditioner assembly process, and achieves the effects of reducing personnel and increasing efficiency.

The utility model also discloses an air conditioner, which comprises the bottom shell. Besides the air conditioner, the air conditioner can be used on other shells 1 which can need to be provided with the motor 3 and the evaporator 5, such as a water cooler, an air cooler and the like.
