Definitions
- the present disclosure relates to clothes dryers and, more particularly, to clothes dryers that distribute air through one or more lifters.
- JP-A-9056991 describes a lifter fixed at the periphery part of a rotary drum and cylindrical seals are fixed at the outer periphery of an air intake plenum and of an air exhaust plenum, so that a circulation passage is formed on the back of the rear wall of the drum.
- the use of two concentric air plenum chambers and related seals makes the above known solution quite complex and not easy to be implemented.
- the process hot air is flowing always and entirely through the lifters, even if the lifters are in an upper position during drum rotation. In this condition, i.e. when the lifters are not in contact with clothes, the effectiveness of having air flowing in the lifter is substantially reduced.
- Another disadvantage of the above known solution is that it cannot be adapted to traditional dryers where air flow enters the drum from a perforated rear wall and leaves the drum from an aperture placed adjacent the front opening of the drum.
- One of the most relevant technical features of a dryer according to this disclosure is the use of a distribution device in the air inlet plenum chamber capable of delivering air to the drum either indirectly, i.e. through one or more lifters, or directly, i.e. though a rear perforated wall of the drum.
- the distribution device is a shaped air plenum chamber which faces only a lower portion of the rear perforated wall, from its side opposite to the drum, so that air is delivered to the drum only though the lower portion of the rear perforated wall. Therefore, when the position of the lifter during rotation of the drum corresponds to the shaped air plenum chamber, air is flowing entirely or partially through the lifter, and when the position of the lifter does not correspond to said air plenum chamber, air is flowing through the plurality of holes of the rear wall of the drum facing the shaped air plenum chamber.
- the shape of said plenum chamber together with the shape of an air conveying base portion of the lifter orthogonal to the active portion of the lifter on the drum side wall (such base portion covering, at a predetermined distance, a part of the perforated rear wall of the drum in order to create a sort of inner chamber) will be responsible on the amplitude of arc during which air is delivered through the lifter.
- the shape of the base portion of the lifter covers substantially a circular sector covering from 60° to 100° of arc of the perforated rear wall of the drum, while the air plenum chamber covers an area a bit wider than said base portion of the lifter, so that at least a percentage of process air flows always through the perforated wall also when the lifter, during its rotation with the drum, it is in a lower portion of the drying chamber. This has been found beneficial in terms of drying efficiency and energy saving.
- lifters for blowing air into the drum as described herein can be implemented without significant modification of existing machines. Moreover, as described herein the air is flowing through the lifter only if this latter is aligned with the distribution device (i.e. inlet air plenum chamber). In this way air flows in the lifter only when this latter is in contact with clothes, i.e. in the lower part of its circular trajectory.
- the distribution device i.e. inlet air plenum chamber
- Another advantage derives from use of a dedicated cycle and the use of separate actuation for drum tumbling and air blowing that enables energy saving and reduced fabric shrinkage.
- the use of “blowing lifters” i.e. use of lifters though which process air can be fed to the drum
- FIG. 1 is an isometric view of an example clothes tumble dryer
- FIG. 2 is an isometric enlarged view of the inside of the drum of FIG. 1 ;
- FIG. 3 is an isometric view of the rear of the drum of FIGS. 1 and 2 ;
- FIG. 4 is a partial cross-sectional view of a detail of FIG. 2 ;
- FIG. 5 is a front view of the perforated rear wall of the drum where the shape of the distributor is shown in solid and dotted line;
- FIG. 6 is a schematic view of how a clothes dryer according to this disclosure works.
- an example tumble dryer 10 includes a cabinet 12 having an upper wall 12 a, a front wall 12 b provided with a hingedly mounted door 14 , side walls 12 c and a rear wall 12 d. Inside the cabinet 12 a rotating drum 16 is mounted which is actuated by an electric motor (not shown) and which defines a drying chamber 17 .
- the drum 16 includes at least one lifter 18 having a plurality of holes 20 for air passage.
- the lifter 18 may be hollow.
- the lifter 18 includes a rear base portion 18 a covers a portion of a rear perforated wall 16 a of the drum in order to convey air entering through the perforated wall 17 a towards the holes 20 of the lifter 18 .
- the rear base portion 18 may have a triangular or circular sector shape.
- the base portion 18 a defines with the facing portion of the rear wall 16 a of the drum 16 a sort of inner chamber 19 (see FIG. 4 ) which covers an arc ranging preferably from 60 to 100° and which communicates with the portion of the lifter 18 fixed to the side wall of the drum 16 .
- the clothes dryer 10 may also have a dispensing system for dispensing treating chemistries into the drum 16 , and including a reservoir 22 that is closed by a cover 24 .
- the clothes dryer 10 is also provided with a controller 26 that may receive input from a user through a user interface 28 for selecting a cycle of operation.
- the clothes dryer 10 also includes an air inlet channel 30 (see FIG. 6 ) and an outlet channel 32 , a heating system (not shown) that heats air entering the drum (e.g. by means of resistors, heat exchangers, etc.), and a blower (not shown) that makes air flowing across the drum 16 .
- the drum outlet 32 where a removable filter 33 for removing fluff or lint is placed, can be eventually connected to the drum inlet 30 thus realizing a closed loop system in which heat exchangers, resistors, heat pump, etc. control the condensation and heating process.
- the drum outlet 32 can be connected to an air vent.
- the lifter 18 functions not only to increase the heat exchange efficiency between air and clothes and improve the evenness of the drying result by means of clothes redistribution during the whole cycle, but also to improve the efficiency of hot air distribution.
- a common drawback of known dryers is that when the load size increases to almost fill the drum volume, the efficiency of the lifter in redistributing the load within the drum is decreased thus leading to the risk of damaging the clothes that are positioned in the rear end of the dryer (where temperatures are higher) and reducing the evenness of drying results.
- the above controlled distribution is carried out by means of a shaped fixed distributor 34 which forms an air inlet plenum chamber upstream the drum 16 .
- the shape of the distributor 34 ( FIG. 5 ) does not corresponds necessarily to the circular sector shape of the base portion 18 a of the lifter 18 , but need not extend higher than the lower half of the drum 16 .
- FIG. 5 two shapes are shown (in dotted and solid lines) which have worked well in tests carried out by the applicants. Such shapes maximize the air flow either though the lifter 18 (when this latter is in the lower positions during rotation) and through clothes adjacent the lifter.
- the enhanced lifter design can be combined with a dedicated cycle design, able to stop tumbling when the lifter 18 is located in a position that minimizes the temperature gradient.
- This approach can furthermore increase the above mentioned advantages and can provide also energy saving benefits due to reduced motor usage.
- One or more lifters of the type disclosed above can also be used together with one or more typical lifters that do not match the above description. Due to the fact that the lifter 18 is physically connected to the drum 16 , during tumbling it changes its position with respect to the air inlet 34 thus leading to a variable air mass flow rate in the lifter 18 and in the drum 16 . This is clearly shown in FIG.
- the examples disclosed herein can improve significantly also the drying and fabric care performances with delicate cycles. As described above, aiming to reduce the mechanical action on this type of loads, the tumbling is often reduced or even avoided; this solution has the negative result of increasing the temperature gradient thus leading to the already discussed drawbacks.
- the machine can be designed to stop tumbling (for the whole cycle or only for part of it, also e.g., using a PWM approach) in a way that the air can flow through the lifter 18 to provide a means to optimize heat flux for these type of loads using appropriate design of the lifter.
- the drum 16 is in a position where the lifter 18 lays on the bottom of the drum 16 , thus having the clothes laying on it.
- the method used to stop the drum 16 in the correct position is well known in the art and it can be easily transferred from the known solutions for top loader washer for having the door in upwards location to facilitate loading and unloading of the drum.
- the lifter 18 can be designed to host a cartridge containing a fragrance or some other chemical additives to improve quality of drying that can be released in the drum 16 .
- the lifter 18 is used with a drum 16 having an air inlet and outlet port on opposite sides thus enabling fine optimization of heat fluxes. Nevertheless the examples disclosed herein can be applied to those drums in which inlet and outlet air connections are located on the same side (with a dedicated air collector similar to air distributor 34 ). In these examples the lifter 18 can be used to convey hot inlet air towards the opposite side of the drum 16 , therefore improving significantly the heat flux distribution in the longitudinal direction.
- FIG. 4 shows a detail of the air distributor 34 which is made preferably by a shaped metal or plastic sheet 35 .
- a sealing means (not shown) can be interposed between the edge of the shaped sheet 35 forming the distributor 34 and the rear wall 16 a of the drum 16 .
