Description

1 TARIFF A DRYER WITH A HEAT TRANSFER ELEMENT This invention utilizes condensate water obtained by condensing drying air. A drying system that prevents the water in the water reservoir from freezing due to cold temperatures. 5 It is related to the machine. In tumble dryers, heated air is blown over the clothes placed inside the drum. It is being sent. Heated air removes moisture from the laundry. Moist air, Condensation of moisture in the air by passing it through an evaporator with a cold surface 10 This is provided. The condensed water is collected in a reservoir via drainage channels. It is transferred. Then, with the help of the pump located in the collection hopper. The condensed water is either drained outside or, usually, in the dryer. The water is sent to the water tank located in the upper section. Located in the collection chamber... Since the pump is positioned at a specific height, it is possible for it to draw in all the water. 15 This does not happen. Therefore, at the end of the drying cycle, a [unintelligible] is formed inside the collection chamber. A certain amount of water remains. If the dryer is kept in a cold environment, the collection... The water remaining in the reservoir freezes. After the water freezes, the dryer... When the pump is attempted to be restarted, the pump inside the frozen water collection tank... This prevents it from working. This situation causes the dryer to not work properly. This leads to... In the current state of the technology, the water accumulating in the collection tank... from a heat pump to prevent freezing or to melt frozen water It has systems in which the heat generated is delivered to the collection tank through different routes. There are tumble dryers available. However, this is generally very expensive and It is inefficient in terms of thermal conductivity. 25 In the European patent application numbered EP3808889, which falls under the prior art, It was determined that the condensate water had frozen, and in order to melt the frozen condensate water... a dryer configured to transfer heat into the collection chamber It is explained. 30 2 The purpose of this invention is to prevent the water in the collection tank from freezing or to prevent the collection a dryer in which frozen water in its reservoir is melted It is the realization of. The first request made to achieve the purpose of this invention and the 5 related to that request The dryer described in the requirements is a machine that consists of a housing inside a casing. It includes a drum suitable for placing laundry to be dried. Drying the machine, the circulation of drying air sent into the drum It includes an air duct where the process takes place. Within the air duct, the air... a heat exchanger that provides heating and air used in the drying process 10 It contains an evaporator that condenses the moisture inside. The water condensed by the evaporator is sent to the collection tank. Specifically... In dryers located in cold environments, inside the collection tray the water not freezing or after the water in the collection tank freezes The collection chamber needs to be heated in order for the melting to occur. The dryer does this 15 Therefore, at least some of the heat inside the air duct is collected in the reservoir. It includes a heat transfer element that enables heat transfer. The heat transfer element, connected to each other in a way that conducts heat, at least part of which is located inside an air duct a first part and at least a portion of it located inside the collection container It has a second part. Thanks to this, 20 obtained from the air heated by the heat exchanger. At least some of the heat is transferred to the collection chamber. In other words, the heat... Heat is obtained from the hot air circulating inside the air duct thanks to the conduction element. The collection chamber is heated using at least part of the heat transfer element. It is manufactured from a material with high thermal conductivity. The heat transfer element is preferably made of a material with high thermal conductivity. 25 from metals with high thermal conductivity such as aluminum, copper, iron, and steel. It is produced in this way. In this way, the heat inside the air duct is transferred into the collection chamber. It is delivered with high efficiency.
