Problems solved by technology

[0021] In particular, in order to reduce the total volume of a single pipe in which the refrigerant flows, the number of stacked fins can be reduced, and thus the length of the straight pipes that make up a single pipe can be reduced; unfortunately, reducing the number of fins also Reduces the total heat exchange surface of the heat exchanger, which reduces the energy efficiency of the heat pump system

Abstract

The present invention is related to a laundry treating appliance (10) comprising: - a cabinet (20); - a drum (30); - a heat pump system (40), using one or more flammable refrigerants, configured for exchanging heat with an operating fluid (50); - a circulating system (60) configured for circulating the operating fluid (50) through the drum (30), wherein the heat pump system (40) comprises a heat exchanger (70a, 70b) comprising: - a plurality of metallic pipes (80); - a plurality of fins (90), stacked, spaced and parallel to one another, each provided with four or more through-holes (100) suitable for housing one of the metallic pipes (80), wherein each of at least two through-holes (101) houses one of the metallic pipes (80), and at least two through-holes (102) of the four or more through-holes (100) of each one of the fins (90) do not house any of the metallic pipes (80).

Description

technical field [0001] The present invention relates to laundry treatment equipment such as laundry washing machines (also known as washing machines), laundry washer-dryers (also known as wash-dryers), tumble dryers, etc. . Background technique [0002] Conventional laundry treatment appliances such as washing machines, washer-dryers, and tumble dryers typically include a cabinet containing a rotatable drum into which the laundry to be treated (ie, to be washed and / or to be dried) can be loaded. in a rotatable drum. [0003] The working fluid (e.g. depending on the type of laundry treatment appliance and the treatment process to be applied, i.e. water, water mixed with wash / rinse additives, air) by means of a circulatory system (depending on the kind of fluid to be circulated, for example comprising pumps, valves, fans, etc.) circulate through the drum. [0004] In some known laundry treatment appliances, the working fluid is heated and / or cooled / dehumidified by a heat pu...
