Abstract

A top ( 119 ) is adapted to match and close from above a cabinet ( 110 ) of a laundry drying appliance ( 100 ). The top is formed as a ready-to-mount part ready to be mounted to the cabinet and forms a moisture condensing module for dehydrating drying air used to dry laundry within a drying drum of the laundry drying appliance. The top has a drying air inlet ( 510 ), a drying air outlet ( 515 ), fluid passageways defined thereinside from said drying air inlet to said drying air outlet for the passage of the drying air to be dehydrated and moisture condensing means arranged inside the fluid passageways.

First claim

The invention claimed is:

1. A top adapted to match and close from above a cabinet of a laundry drying appliance, the top being formed as a ready-to-mount part ready to be mounted to the cabinet, the top comprising lateral walls, an upper worktop surface, and a bottom surface and forming a moisture condensing module for dehydrating drying air used to dry laundry within a drying drum of the laundry drying appliance, the top having:
a drying air inlet,
a drying air outlet,
fluid passageways defined thereinside from said drying air inlet to said drying air outlet for the passage of the drying air to be dehydrated, and
a moisture condenser arranged inside said fluid passageways,
wherein the moisture condenser comprises a heat pump evaporator fluidly coupled or couplable to a compressor body by means of a pipe, wherein an upper portion of said compressor body is attached to the bottom surface of the top below the upper worktop surface of the top, and a lower portion of the compressor body extends from the bottom surface of the top to a lower end of the compressor body, wherein the lower end of the compressor body hangs freely below the bottom surface; and
a heat pump condenser downstream of said heat pump evaporator.

2. The top of claim 1 , wherein said drying air inlet and said drying air outlet are provided on the bottom surface.

3. The top of claim 1 , further comprising a condense water drainage outlet for draining condense water released by the drying air upon passing through the moisture condenser.

4. The top of claim 1 , wherein said fluid passageways for the drying air comprise a first air path portion extending from the drying air inlet to the moisture condenser, and a second air path portion extending from the moisture condenser to the drying air outlet.

5. The top of claim 4 , further comprising a defluff filter accommodated in the first air path portion.

6. The top of claim 5 , wherein the defluff filter is in a form of a drawer hinged at one end to the top and pivotable so as to allow extraction.

7. The top of claim 4 , further comprising a condense water droplets separator provided in the second air path portion, for removing condense water droplets from the drying air before the drying air reaches the drying air outlet.

8. The top of claim 7 , wherein the water droplets separator comprises a sump and a baffle extending down in the sump for defining a siphon.

9. The top of claim 8 , wherein the condense water drainage outlet is fluidly connected to the sump.

10. The top of claim 8 , wherein the water droplets separator further comprises a condense water tank fluidly connected to the sump and to a point of the second path portion downstream of the water droplets separator.

11. The top of claim 7 , wherein the water droplets separator comprises a baffle that separates an area of the top where the heat pump evaporator is accommodated, from an area of the top where the heat pump condenser is placed, the baffle forming a barrier for the condense water that drops from the drying air when it passes through the heat pump evaporator.

12. The top of claim 11 , wherein the top comprises a base element in which said drying air inlet and said drying air outlet are provided in the base element, said condense water droplets separator being provided in a region of the base element under the heat pump evaporator, in which region under the heat pump evaporator the base element is slanted towards said baffle.

13. The top of claim 12 , wherein channels are formed in the base element in the area thereof under the heat pump evaporator to facilitate the drainage of the condense water.

14. The top of claim 13 , further comprising a condense water drainage outlet for draining condense water released by the drying air upon passing through the moisture condenser wherein said condense water drainage outlet is formed in said area of the base element under the heat pump evaporator.

15. The top of claim 1 , wherein said drying air outlet is configured to couple to an intake of an air circulation fan.

16. The top of claim 1 , wherein the upper portion of the compressor body is attached to the top at an abutting upper side of the bottom surface of the top, and the lower portion of the compressor body extends from a side opposite the upper side of the bottom surface of the top to the lower end of the compressor body.

17. A laundry appliance comprising:
a cabinet comprising:
a front wall, sidewalls and a back wall,
an open upper end,
a cabinet outlet adjacent to and facing the open upper end,
an air circulation fan having an intake adjacent to and facing the open upper end; and

a top adapted to cover the open upper end of the cabinet, the top being formed as a ready-to-mount part ready to be mounted to the cabinet, the top comprising lateral walls, an upper worktop surface, and a bottom surface and forming a moisture condensing module for dehydrating drying air used to dry laundry within a drying drum of the laundry drying appliance, the top having:
a drying air inlet positioned to couple to said cabinet outlet,
a drying air outlet positioned to couple to said air circulation fan intake,
fluid passageways defined thereinside from said drying air inlet to said drying air outlet for the passage of the drying air to be dehydrated, and
a moisture condenser arranged inside said fluid passageways and comprising a heat pump evaporator fluidly coupled or couplable to a compressor body by means of a pipe, wherein an upper portion of said compressor body is attached to the bottom surface of the top below the upper worktop surface of the top, and a lower portion of the compressor body extends from the bottom surface of the top to a lower end of the compressor body; and
a heat pump condenser downstream of said heat pump evaporator.

18. The laundry appliance of claim 17 , wherein the upper portion of the compressor body is attached to the top at an abutting upper side of the bottom surface of the top, and the lower portion of the compressor body extends from a side opposite the upper side of the bottom surface of the top to the lower end of the compressor body.
