Example one
As shown in fig. 2, the present embodiment provides a heat pump clothes dryer including a casing 1, a drum 2 disposed inside the casing 1, a circulation duct, a heating assembly, and a heat exchanging mechanism. Both ends of the circulation duct are respectively communicated with the front side and the rear side of the drum 2 so as to circulate the air flow inside the drum 2. Wherein, the front side of the drum 2 is the side facing the user when the heat pump clothes dryer is used, and correspondingly, the rear side of the drum 2 is the side facing away from the user when the heat pump clothes dryer is used. The heat exchange mechanism and the heating assembly are both arranged in the air duct.
In this embodiment, as shown in fig. 2 and 3, the circulating air duct includes a front air duct 31 communicated with the bottom of the front side of the drum 2, the front air duct 31 is connected to a lower air duct 32 located below the drum 2, and the lower air duct 32 is connected to a rear air duct 33 located at the rear side of the drum 2. The rear duct 33 is located at the rear side of the drum 2 and may extend vertically, and the upper end of the rear duct 33 communicates with the drum 2 so that air circulates. Alternatively, the air in the drum 2 may pass through the front duct 31, the lower duct 32, and the rear duct 33 in sequence and then return to the drum 2.
Optionally, the heating assembly may be disposed in the rear air duct 33 near a position communicating with the drum 2, so that air passing through the heating assembly directly enters the drum 2, thereby reducing heat loss in the air duct and improving drying efficiency.
When the heat pump clothes dryer is used, wet clothes are placed in the roller 2, air in the circulating air channel is heated by the heating assembly to form high-temperature gas, the high-temperature gas enters the roller 2 to contact with the wet clothes to absorb moisture in the wet clothes to form damp and hot air, the damp and hot air enters the air channel to be cooled by the heat exchange mechanism to form dry air, the dry air enters the roller 2 after passing through the heating assembly again, and the purpose of drying the clothes is achieved through the circulating flow of the air. The heating assembly can be a structure which adopts a heating wire or a thermistor (PTC) and the like to realize heating, the heating wire or the thermistor generates heat after being electrified, and the heat is dissipated to the ambient air to realize air heating.
The heat exchange mechanism comprises an evaporator 4 and a condenser 5, and the damp and hot air entering the circulating air duct sequentially passes through the evaporator 4 and the condenser 5. The evaporator 4 is used for condensing the hot and humid air, removing moisture in the hot and humid air, and forming dry air. A water collecting box is also arranged in the circulating air duct, and the water collecting box is arranged below the evaporator 4 and used for collecting condensed water. The dried air is heated by the condenser 5, and the heat emitted when the damp and hot air is condensed is absorbed, so that the utilization rate of the heat is improved.
In the prior art, the evaporator 4 and the condenser 5 are arranged in the front-rear direction and are disposed in the lower duct 32. The condenser 5 and evaporator 4 tend to be large in volume to meet the heating and condensing requirements. Since the motor, the fan, the drain pump and the like are required to be disposed below the drum 2, the lower air duct 32 is a narrow and long air duct extending in the front-rear direction, so that the windward areas of the evaporator 4 and the condenser 5 are limited, the sizes of the evaporator 4 and the condenser 5 in the front-rear direction are large, and the flow path of the air flow passing through the evaporator 4 and the condenser 5 is long, thereby causing a large wind resistance of the air flow. In order to overcome the wind resistance, the wind pressure of the fan is designed to be higher, so that the power consumption is greatly increased, and the drying time is prolonged.
In order to solve the above problem, in the present embodiment, the evaporator 4 and the condenser 5 are disposed in the lower air duct 32, and the air intake surface of at least one of the evaporator 4 and the condenser 5 extends along the length direction of the lower air duct 32, that is, the air intake surface is disposed in front of and behind, so that the flow direction of the air flow passing through the evaporator 4 and/or the condenser 5 is perpendicular to the length direction of the lower air duct 32.
In order to increase the air intake area to the maximum extent and reduce the wind resistance, in the embodiment, the evaporator 4 and the condenser 5 are both horizontally arranged in the lower air duct 32, and the condenser 5 is located above the evaporator 4. The bottom surface of the evaporator 4 and the bottom surface of the condenser 5 are air inlet surfaces, so that under the condition that the volumes of the evaporator 4 and the condenser 5 are not changed, the air inlet surfaces can be increased, correspondingly, the length of an air flow flowing through a route (namely, the distance along the height direction of the evaporator 4 and the condenser 5) can be relatively reduced, the purpose of reducing wind resistance is achieved, air flow circulation is smoother, the reduction of energy consumption is facilitated, and the working efficiency of the heat pump clothes dryer is improved.
Moist hot air enters the evaporator 4 from the bottom surface and then is condensed, condensed water drops into the water collecting box below under the action of gravity, stripping of the condensed water is facilitated, the condensed water is prevented from entering the condenser 5, and dried air flow enters the condenser 5 to absorb heat. Alternatively, the condenser 5 may be located directly above the evaporator 4, or may be disposed offset from the evaporator 4. In this embodiment, in order to maximize the air intake surface of the evaporator 4 and the condenser 5, the condenser 5 may be located directly above the evaporator 4.
In other embodiments, the evaporator 4 and/or the condenser 5 may be disposed in the front air duct 31 or the rear air duct 33, as long as the air flow direction passing through the evaporator 4 and/or the condenser 5 is perpendicular to the length direction of the corresponding air duct. In other embodiments, the arrangement of the circulating air duct may also be different.
Example two
The present embodiment provides a heat pump clothes dryer, which is different from the first embodiment in that, as shown in fig. 4, the top surface of the evaporator 4 is an air inlet surface, the condenser 5 is located below the evaporator 4, and the air flow passes through the evaporator 4 and the condenser 5 from top to bottom in sequence.
In order to reduce the influence of condensed water condensed by the evaporator 4 on the condenser 5 and ensure the normal operation of the condenser 5, the evaporator 4 and the condenser 5 can be arranged in a staggered manner. Alternatively, the evaporator 4 and the condenser 5 may be completely staggered, i.e. the projections of the evaporator 4 and the condenser 5 in the horizontal plane are not coincident, so that condensed water is prevented from entering the condenser 5.
EXAMPLE III
As shown in fig. 5, the present embodiment provides a heat pump dryer, which is different from the first embodiment in that the air inlet surfaces of the evaporator 4 and the condenser 5 are vertically disposed. The air flow passes through the evaporator 4 and the condenser 5 in sequence along the left and right directions, and the purposes of increasing the air inlet area and reducing the wind resistance can be achieved, so that the air flow is smoother, the energy consumption is reduced, and the working efficiency of the heat pump clothes dryer is improved.
Example four
The present embodiment provides a heat pump dryer, which is different from the above embodiments in that, as shown in fig. 6, the air inlet surface of the evaporator 4 and/or the condenser 5 is obliquely arranged along the length direction of the lower air duct 32, so that the size of the space formed between the air inlet surface of the evaporator 4 and/or the condenser 5 and the circulating air duct is gradually changed and gradually reduced along the flowing direction of the air, that is, the end of the space near the upstream of the air is large in volume, so that the air enters the air inlet surface more smoothly, so as to reduce the wind resistance.
Specifically, in the present embodiment, both the evaporator 4 and the condenser 5 are disposed obliquely so as to minimize wind resistance. Taking the evaporator 4 as an example, one end of the air inlet surface of the evaporator 4 close to the upstream of the air flow, that is, one end of the air inlet surface of the evaporator 4 (the bottom surface of the evaporator 4) close to the front side, is tilted upward, so that an air inlet formed between the bottom surface of the evaporator 4 and the inner wall of the lower air duct 32 is large, the air flow in the lower air duct 32 can smoothly pass through the air inlet surface, so as to enter between the inner wall of the circulating air duct and the air inlet surface of the evaporator 4, and thus, the air flow is condensed by the evaporator 4, which is beneficial to further reducing the wind resistance.
Optionally, the condenser 5 may be disposed in parallel with the evaporator 4, so that the condenser 5 is also inclined, and one end of the air outlet surface of the condenser 5, which is close to the downstream of the air flow (i.e., one end of the air outlet surface of the condenser 5, which is close to the rear side), is inclined downward, so that an air outlet formed by the air outlet surface of the condenser 5 and the inner wall of the lower air duct 32 is increased, and the air flow passing through the condenser 5 can be smoothly discharged, which is beneficial to further reducing the wind resistance.
Optionally, the angle of inclination of the wind entry face of the evaporator 4 may be 30 ° -50 °, for example 30 °, 32 °, 34 °, 36 °, 38 °, 40 °, 42 °, 44 °, 46 °, 48 °, 50 °.
In other embodiments, the inclination angles of the evaporator 4 and the condenser 5 may also be different.
EXAMPLE five
The present embodiment provides a heat pump dryer, which is different from the above embodiments in that a condenser 5 is provided in a rear air duct 33, as shown in fig. 7. By disposing the condenser 5 in the rear air duct 33, the number of components in the lower air duct 32 can be reduced, so that the volume of the evaporator 4 can be further increased, and the corresponding air intake surface can be increased accordingly.
Optionally, after the condenser 5 is disposed in the rear air duct 33, the evaporator 4 may adopt any arrangement manner in the above embodiments, so as to further increase the air inlet surface and reduce the wind resistance.
Optionally, the rear air duct 33 is vertically arranged, the airflow flows in the rear air duct 33 in a substantially vertical direction, and the air inlet surface of the condenser 5 may be parallel to the bottom surface of the drum 2, so that the flow direction of the airflow passing through the condenser 5 is perpendicular to the flow direction of the airflow in the rear air duct 33, thereby increasing the air inlet area of the condenser 5 and reducing the wind resistance.
The above description is only a preferred embodiment of the present invention, and for those skilled in the art, the present invention should not be limited by the description of the present invention, which should be interpreted as a limitation.
