In addition, the protective bulkhead 93 of mounting portion 7 is the state that abuts with the flange 63a of drip tray 6 in Fig. 8 A, but for the ease of
Understand, gap is shown between protective bulkhead 93 and flange 63a.Similarly, in Fig. 8 C, the protective bulkhead 92 and drip tray 6 of mounting portion 7
Flange 63a be abutting state, but in order to make it easy to understand, gap is shown between protective bulkhead 92 and flange 63a.
Learn the operator that the discharge water of drip tray 6 is substantially filled by notice, in order to by drip tray 6 from showcase 1A
In take out, remove skirting board 2c (referring to Fig. 5) from showcase 1A.The front openings 2d of Machine Room 4 occurs as a result, becomes Fig. 6 institute
The state shown.In addition, the discharge water being omitted in Fig. 6 in drip tray 6.
Moreover, if 6 forward face of drip tray is open before 2d by operator by manual operation from state shown in fig. 6
Side pulls, and the inner wall of the rear wall 63 of drip tray 6 is abutted with the protective bulkhead 93 of mounting portion 7 afterwards, and float switch 10 is by drip tray 6
Rear wall 63 inner wall and its flange 63a press forwards.As a result, as shown in Figure 8 A, float switch 10 and rotatable parts 9
Position, the i.e. retreating position for integrally rotating and being located on drip tray 6 forwards.If operator further by drip tray 6 to
Front pulls, then drip tray 6 is extracted completely from Machine Room 4.
At this moment, the abutting state of rotatable parts 9 and flange 63a is released from, and the float switch 10 of lower end rotates downwards,
Until towards vertical lower section.
Then, if operator will be discharged water emptying after, by drip tray 6 from front surface opening 2d by manual operation to
Rear push-in, then as shown in Figure 8 B, the flange 63a of the rear wall 63 of drip tray 6 is abutted with rotatable parts 9.If operator is by water receiving
Disk 6 is pushed further into, then as shown in Figure 8 C, float switch 10 is pressed by flange 63a, is integrally rearward turned with rotatable parts 9
Position, the i.e. retreating position for moving and being located on drip tray 6.
If the state shown in Fig. 8 C, drip tray 6 is pushed further into, then the abutting state of rotatable parts 9 and flange 63a
It is released from, so float switch 10 naturally returns into detectable position as described above.
Later, drip tray 6 is pushed by operator, until drip tray 6 is accommodated in Machine Room 4 as shown in Figure 6 completely, it
Afterwards, front surface opening 2d is closed using skirting board 2c (referring to Fig. 5), thus completes discharge water process.
In this way, showcase 1A according to the second embodiment of the present invention, float switch 10 are corresponding to the discrepancy of drip tray 6
Ground, the retreating position turned on drip tray 6 or the detectable position for being able to detect discharge water water level.Therefore, by making to float
Mark switch 10 can rotate the structure simplified in this way to the discrepancy direction of drip tray 6, and operator can be easy to carry out 6 phase of drip tray
Discrepancy for Machine Room 4.
In addition, float switch 10 no external force effect under natural conditions, detectable position is located at because of self weight, therefore
The operation for making float switch 10 be back to from retreating position detectable position is not needed, operator can more easily carry out
The discrepancy of drip tray 6.
In addition, due to the presence of the protective bulkhead 93 at rear, being prevented when as shown in Figure 8 A extracting drip tray 6 forwards
The collision of the rear wall 63 or flange 63a of float switch 10 and drip tray 6.In addition, as shown in figs. 8 b and 8 c by drip tray 6
When being rearward pushed into, due to the presence of the protective bulkhead 92 in front, it is therefore prevented that the rear wall 63 or flange of float switch 10 and drip tray 6
The collision of 63a.
That is, due to being provided with protective bulkhead 92,93 on discrepancy direction, that is, front-rear direction of drip tray 6 to float switch 10,
Therefore float switch 10 can be protected in the discrepancy of drip tray 6.
Also, since protective bulkhead 92,93 is set to the lower end of rotatable parts 9, because of the weight of protective bulkhead 92,93,
The posture of rotatable parts 9 is easily made into the posture of float switch 10 downward.Therefore, even if in the measurement of discharge water water level
Buoyancy acts on rotatable parts 9 via buoy 12, is also able to suppress the inclination of rotatable parts 9, can be in discharge water water level
In measurement, the posture of rotatable parts 9 is maintained into the posture that float switch 10 is in detectable position.
In addition, the flange 80a of the base end part as bearing part 8, is fixed on Machine Room bottom surface 4a.The roof of Machine Room 4
It is made of heat-barrier material, therefore intensity is lower, moreover, because there are certain bumps, so being difficult to be stably installed bearing part
8.Therefore, it by the way that flange 80a to be fixed on to the bottom wall of Machine Room 4, compared with the case where being installed on roof, can support securely
Bearing part 8.
In addition, can also obtain identical effect by the side wall that the base end part of bearing part 8 is installed on to Machine Room 4.
Showcase 1A according to the present embodiment, compressor 5e are set to the upper surface 2b of main body cabinet 2, thus can obtain with
The identical effect of first embodiment and effect.
[2-4. variation]
In the following, being illustrated to variation.
(1) float switch 10 is configured to be located at detectable position because of self weight in its natural state, but can also be such as
Spring is set between bearing part 8 and rotatable parts 9, is exerted a force to rotatable parts 9 to detectable position using the spring.
Even if as a result, in the case that due to change year in year out etc. rotatable parts 9 become rotation no longer smoothly, can also make to float
Mark switch 10 steadily restores from retreating position to detectable position.Turn in addition, being able to suppress when the rising of water water level is discharged
Dynamic component 9 unnecessarily rotates.
Alternatively, can also be by the way that the mutual frictional resistance of bearing part 8, rotatable parts 9 and screw 94 be set to
The means such as higher are come so that rotatable parts 9 are not just rotated without external force.In this case, for float switch 10 from moving back
Recovery of the position to detectable position is kept away, as long as rotating rotatable parts 9 by being manually operated by operator.In the feelings
Under condition, it is able to suppress the unnecessary rotation of the rotatable parts 9 when the rising of discharge water water level.
Identical with first embodimently, electrical box 5f can also be configured to Machine Room 4.
