DETAILED DESCRIPTION

(9) To make technical problems solved by the present disclosure, technical solutions adopted by the present disclosure, and achieved technical effects more clear, the technical solutions in embodiments of the present disclosure will be further described in detail below in combination with drawings. Apparently, described embodiments are merely some embodiments of the present disclosure, not all of the embodiments. All other embodiments obtained by those skilled in the art without contributing creative labor based on embodiments in the present disclosure belong to a protection scope of the present disclosure.

Embodiment I

(10) With respect to problems of need of connection with an exhaust pipeline, inconvenient installation and incapability in energy saving in an existing directly-drained clothes dryer, and problems of low drying speed and the like in an existing condensation-based clothes dryer, a new condensation-based clothes dryer is proposed. As shown in FIG. 3, a condensation-based clothes dryer provided in the present embodiment includes a box body 1, a drum 2, a front hot air duct 3, a rear hot air duct 4, an air chamber 5, a fan 6 (or air blower) for driving air from an inlet to an outlet through an air duct, a motor, a heater 7 for heating air, a master control board and a condenser 8 arranged outside the box body 1. The rear hot air duct 4, the drum 2, the front hot air duct 3 and the air chamber 5 are communicated to form a circulating air duct. The condenser 8 has a condensation air duct 10 and a cooling air duct 11. An inlet end of the condensation air duct 10 is communicated with an air outlet in the box body 1, and an outlet end of the condensation air duct 10 is communicated with outside air. An inlet end of the cooling air duct 11 is communicated with outside air, and an outlet end of the cooling air duct 11 is communicated with an air inlet in the box body 1. A condensate water collecting box 9 is arranged below the condenser 8.

(11) In the present embodiment, as a solution of the above condensation-based clothes dryer, the fan 6 is arranged in the air chamber 5; the heater 7 is arranged in the rear hot air duct 4; and, the air inlet in the box body 1, the rear hot air duct 4, the drum 2, the front hot air duct 3, the air chamber 5 and the air outlet in the box body 1 are successively communicated to form a circulating air duct.

(12) The present embodiment further proposes a condensation-based clothes drying method applied to the above condensation-based clothes dryer. The motor drives the fan and the drum 2 arranged in the air chamber 5 to rotate, so that outside air enters the hot air duct 4 of the box body 1 through the cooling air duct 11 of the condenser 8 and the air inlet in the box body 1, and becomes damp and hot air after heated by the heater 7; the damp and hot air enters the condensation air duct 10 of the condenser 8 through the front hot air duct 3 after heating clothes in the drum 2, and performs heat exchange with outside air that enters the box body 1 through the cooling air duct 11 of the condenser 8; moisture in the damp and hot air is condensed into water; the damp and hot air becomes dry and hot air and is exhausted; and outside air enters the box body 1 after absorbing heat to dry clothes according to the above circulation mode.

(13) To remove massive vapor included in the damp and hot air exhausted by the drum 2, the discharged damp and hot air can be exhausted after lowering temperature and removing dampness, thereby omitting a project of installing an exhaust pipeline in an existing directly-drained clothes dryer. The condenser 8 is additionally arranged outside the box body 1, and the damp and hot air including massive vapor is cooled by using the condenser 8, so that moisture in the damp and hot air is condensed into water and the damp and hot air becomes dry and hot air and is exhausted; and the dry and cold air at the air inlet enters the clothes dryer after absorbing heat through the condenser 8 to dry clothes, thereby not only saving energy and reducing cost, but also shortening drying duration and increasing drying speed.

(14) In the present embodiment, as a solution of the above condensation-based clothes dryer, to increase heat conduction efficiency, the condenser 8 is made of hot superconductive material such as aluminum or copper or plastic and the like so as to form a multilayer sheet structure.

(15) As a solution of the above condensation-based clothes dryer, a temperature detection apparatus is installed in the box body 1. When the temperature detection apparatus detects that the temperature of the box body 1 is higher than a set temperature, the heater 7 stops operating and the rest systems continue to operate, so that the temperature in the box body 1 is not too high and clothes would not be damaged.

(16) As a solution of the above condensation-based clothes dryer, a humidity detection apparatus is further installed in the box body 1. When the humidity detection apparatus detects that the humidity is lower than a set value before preset duration of a drying procedure is ended, the clothes dryer stops operating, thereby realizing stop of clothes drying when clothes are dried so as to save energy consumption. When the humidity detection apparatus detects that the humidity is higher than a set value after the preset duration of the drying procedure is ended, the clothes dryer prolongs a period of drying duration until humidity achieves the set value.

Embodiment II

(17) The present embodiment provides another new condensation-based clothes dryer. As shown in FIG. 4, a structure of the condensation-based clothes dryer described in the present embodiment is different from a structure of the condensation-based clothes dryer described in embodiment I in that: in the present embodiment, the fan 6 is arranged in the rear hot air duct 4; the heater 7 is arranged in the air chamber 5; and, the air inlet in the box body 1, the air chamber 5, the front hot air duct 3, the drum 2, the rear hot air duct 4 and the air outlet in the box body 1 are successively communicated so as to form a circulating air duct. Namely, a circulation order of air in the box body 1 in the present embodiment is as follows: the air inlet in the box body 1the air chamber 5the front hot air duct 3the drum 2the rear hot air duct 4the air outlet in the box body 1. The condensation-based clothes drying method is similar to the condensation-based clothes drying method described in embodiment I, and is not repeated herein. A linkage form of the circulating air duct in the box body of the condensation-based clothes dryer in the present application is not limited to the above condition but can be randomly designed as long as clothes in the drum can be dried through the circulation of air.

(18) Compared with an existing condensation-based clothes dryer, the present application adopts only one fan (or air blower) to realize air circulation and drive heat transmission. Therefore, the cost of the present application is lower.

(19) The condenser in the present application may be an individual module. When the condenser is taken away, what has left is a directly-drained clothes dryer; and when the condenser is installed, discharge of moisture can be reduced. Exhausted heat is used for saving energy, so as to form an open condensation-based clothes dryer. An air blower is added on the condenser to close the system to form a complete condensation-based clothes dryer. Therefore, the present application has an advantage of multiple purposes by one apparatus, and can greatly increase product competitiveness.

(20) It shall be noted that the above contents are only embodiments of the present disclosure and used technical principles. It can be understood for those skilled in the art that the present disclosure is not limited to specific embodiments described herein. For those skilled in the art, the present disclosure can be subject to various apparent variations, readjustments and replacements without departing from a protection scope of the present disclosure. Therefore, although the present disclosure is described in detail through above embodiments, the present disclosure is not only limited to above embodiments. The present disclosure can also include more other equivalent embodiments without deviating from conceptions of the present disclosure. A scope of the present disclosure is determined by a scope of attached claims.
