ABSTRACT:
BAKGROUND OF THE INVENTION
This invention relates to a support frame for an ice-storing tank for an air conditioner with an ice-storing mode, particularly to one possible to increase connection and support strength.
Applicant of this invention filed a patent application titled “ICE-STORING TANK FOR AN AIR CONDITIONER WITH AN INCE-STORING MODE” on Aug. 11, 1999 with Ser. No. 09/371,852.
As shown in
FIGS. 10-13
, the application of Ser. No. 09/371,852 includes spiral tube units
2
in a temperature-preserving tank
1
, which has an characteristic that each spiral tube unit
2
has a base
3
and a plurality of vertical long rods
4
at an outer edge. A plurality of independent coil tubes
5
are placed on the base
3
, and each coil tube
5
having a hollow tube
52
is placed circling around on the support frames
51
arranged in radial direction. The outer ends of the support frames
51
are connected tightly to the long frames
4
, and the hollow tube
52
has a joint at two ends. A vertical inlet tube
6
and a vertical outlet tube
7
are positioned outside of the base, respectively having a plurality of connect mouths
61
,
71
for the joints of the two ends of each hollow tube
52
to screw with and communicate with one another. The upper ends of the inlet tube
6
and the outlet tube extend out of the temperature preserving tank
1
to form an inlet and outlet for coolant liquid to flow in and out. If any of the hollow tubes
52
leaks, each spiral tube
5
is orderly taken out for check to find which one leaks, without need of breaking the floor to use a crane to hang up and out the heavy and large spiral tube unit, facilitating repair and saving expenditure.
However, the support frames
51
for spiral tube units
5
has plural rods having inner ends not properly connected with each other, so their connection and support strength have to be reinforced. Therefore, this invention has been devised.
SUMMARY OF THE INVENTION
This invention is to offer a support frame for an ice-storing tank for an air conditioner with an ice-storing mode, and the ice-storing tank consists of plural spiral tube units contained in the temperature preserving tank. The spiral tube units are positioned on a base and a plurality of vertical long rods fixed around the outer circumference of the base. Then, a plurality of independent spiral tubes are orderly placed on the upper surface of each support frame. Each rod of the support frames arranged in a radial direction has a plurality of grooves for the spiral hollow tubes to fit therein, and the outer ends of the rods of each support frame are connected tightly to the vertical long rods. A vertical inlet tube and a vertical outlet tube are installed outside the base, connected to the two ends of each hollow tube, and extends out of the temperature preserving tank to form an inlet and an outlet for coolant liquid. The characteristic is a connector for connect inner ends of the rods of the support frames to increase tightness of mutual combination and strength of the support frames, and thus also the support strength.
