Abstract

The present application provides a refrigerated display case. The refrigerated display case may include a tub assembly and a drain system in communication with the tub assembly. The drain system may include an integrated tee joint-drain trap.

First claim

I claim:

1. A refrigerated display case,
comprising:
a tub assembly;
a drain system in communication with the tub assembly;
the drain system comprising an integrated tee joint-drain trap; and
the integrated tee joint-drain trap comprising:
a tee joint for providing flow in three directions, the tee joint having an inlet for receiving a flow of a liquid and a first outlet and a second outlet, the tee joint for fluid communication with a drain line,
a drain trap coupled to and underneath the tee joint, the drain trap formed with an interior volume in fluid communication with the tee joint for receiving liquid and holding at least a apportion of the liquid, and
wherein the drain trap comprises a drain access port for providing access to the interior volume, and a drain plug for mating with the drain access port.

2. The refrigerated display case of claim 1 , wherein the drain system wherein the drain line is in fluid communication with the integrated tee joint-drain trap.

3. The refrigerated display case of claim 1 , wherein the integrated tee joint-drain trap is positioned along a front of the refrigerated display case.

4. The refrigerated display case of claim 1 , wherein the integrated tee joint-drain trap comprises a flow divider positioned proximate the inlet.

5. The refrigerated display case of claim 1 , wherein the integrated tee joint-drain trap comprises a pair of trap dividers extending into the interior volume.

6. The refrigerated display case of claim 5 , wherein the integrated tee joint-drain trap comprises a flow path in the interior volume and around at least one of the trap dividers.

7. The refrigerated display case of claim 6 , wherein the flow path comprises a substantially U shape.

8. The refrigerated display case of claim 1 , wherein the drain trap comprises a drain box and wherein a portion of the drain box is formed by a drain cap forming at least a portion of a wall of the drain box.

9. An integrated tee joint-drain trap positioned along a front of a refrigerated display case, the integrated tee joint-drain trap comprising:
an upper tee joint having an inlet for receiving a liquid drained from refrigeration components of the refrigerated display case and a first outlet and a second outlet for communicating liquid to a drain;
a lower drain trap integral with the upper tee joint and in fluid communication with the upper tee joint, the lower drain trap having a drain box and forming a interior volume in the drain box for receiving liquid; and
a drain access port formed in the drain box for providing access to the interior volume.

10. The integrated tee joint-drain trap of claim 9 , wherein the drain box further comprises a pair of trap dividers projecting into the interior volume to define a flow path therein.

11. The integrated tee joint-drain trap of claim 9 , wherein the
drain box comprises a drain cap.

12. The integrated tee joint-drain trap of claim 9 , further comprising a drain plug for selectively sealing the drain access port.
