D06F39/10 - Filtering arrangements
SUBSTANCE: proposed is a household laundry dryer containing a box-shaped body (3), a rotary drum, a calorifier (8) ensuring hot air flow circulation, a ventilation means (10) creating along the recirculation pipeline (9) air flow (f) through the rotary drum (4), a filtering element (1), positioned in the air flow recirculation pipeline (9) upstream at least one air flow cooling means (13) designed so that to enable easily dismountable installation into the recession (3b) made in the external edge of the laundry charging/discharging hole (3a). The filtering element (1) contains a plastic support plate (20) (designed so that to enable easily dismountable installation into the recession (3b) made in the external edge of the laundry charging/discharging (3a) of the laundry dryer (2) so that to ensure complete closure of such recession (3b), and an essentially hollow housing (21) in the form of a container projecting from the rear surface of the support plate 20 into the inner part (9b) of the air recirculation pipeline (9) of the laundry dryer (2). The hollow housing (21) is fabricated integrated with the support plate (20) by means of pressure casting and is divided into two mutually complementary parts (22a, 22b) in the form of wings pivotally interconnected along the side line. The filtering element (1) additionally contains an O-ring seal (24) made of thermoplastic elastomer and applied onto the whole of the external edge of the support plate (20) and/or a second O-ring seal (25) made of thermoplastic elastomer and applied along the whole of the connective external edge of at least either of the two parts (22a, 22b) of the hollow housing.
The invention relates to a filter element for a household tumble dryer, in particular, for domestic drum dryer containing a heater and a closed loop and is described hereinafter as an example.
As is known, modern appliances drum dryer usually contain external enclosure, essentially in the form of a parallelepiped; a cylindrical drum to be placed in it to be drying, which is installed in the housing for rotation about its horizontal longitudinal axis opposite the hole for loading/unloading in the front panel; a door pivotally mounted on the front panel can be rotated from the open position to the closed position in which the door is completely pressed to the body, blocking the hole in the front panel of the case and ensuring the sealing of the rotating drum; and a motor for rotating the drum around its longitudinal axis inside the case.
This household tumble dryer also contains a heater closed loop to circulate inside the rotating drum of hot air with low moisture content, which passes through the rotating drum and through located inside his underwear for his quick drying.
Most sold in the last time b is ribannah dryer for linen heater with a closed contour contains the pipeline recirculation attached by its two ends to the rotating drum at its opposite sides; an electric centrifugal fan located along the recirculation pipe to create inside the air flow, which flows through the rotating drum; and finally, the heat pump unit containing two heat exchanger, arranged one after another along the pipeline and air circulation. The first heat exchanger air/refrigerant" heat pump unit provides fast cooling air flow coming from the rotating drum to condense excess moisture; and the second heat exchanger air/refrigerant" heat pump unit provides rapid heating of the air flow coming from the first heat exchanger and sent back to the rotating drum. Thus, again incoming into the rotating drum, the flow of air is rapidly heated to a temperature higher than the temperature coming out of the rotary drum air or equal to this temperature.
To prevent smaller pieces and/or fibers in a centrifugal fan, and both of the heat exchanger of the heater also includes at least one filter element, located along the pipeline recirculation air flow in front of a centrifugal fan, which in its turn is, usually located on the stream before the first heat exchanger air/refrigerant".
In particular, the input section of the pipeline recirculated air is usually divided into two consecutive sections, the first of which is built into the door of the dryer. This heater contains two independent filter element, located respectively along the first and second sections of the inlet pipe of the pipeline and air circulation.
In particular, the first section of the inlet pipe of the pipeline recirculated air passes through the door of the dryer, and the first filter element is typically formed by a mesh membrane covering the inlet opening of the first section formed on the rear side of the door. The second section of the inlet pipe of the recirculation pipe air acts in the body of the dryer from the notch made in the outer edge of the hole for loading/unloading, while the second filter element is typically formed of wedge-shaped filter element, which is inserted into the groove made in the outer edge of the hole for loading/unloading.
It is obvious that in the closed position of the door drum dryer is configured to align the first section of the inlet pipe of the pipeline recirculation of air from the second section of the inlet pipe of the pipeline racer is ulali air, thereby allowing the air coming from the rotating drum, to pass freely to the heat pump unit.
In the document GB 2116068 described wedge-shaped filter element for dryer, which contains a rigid casing in the form of a container of V-shaped cross section, and its size can insert it into the groove made in the outer edge of the hole for loading/unloading. Along its longitudinal median plane of the rigid casing divided into two equal portions in the form of shutters are pivotally connected along the lateral line, so that a hard cover can be opened like a book. The bottom wall of each part in the form of a leaf has two large apertures, each of which is fully covered by a grid of small cells that can hold a feather and/or fibers in the inner part of the hard casing in the form of a container.
Along the connecting outer edges of each part in the form of a leaf filter element also contains one protruding outward folding grid, which is designed to overlap the protruding outward folding of the grid to a different part of the leaf, forming a labyrinth seal.
Unfortunately, the labyrinth seal is made along the connecting outer edges of the two parts in the form of a leaf, is not as effective when the delay is Sri slightest smaller pieces and/or fibers, therefore, they can achieve the first heat exchanger air/refrigerant", deposited there and slow the cooling air exiting the rotating drum.
To address this shortcoming in some dryers for Laundry there is a third filter element, located along the pipeline recirculation air flow immediately prior to the first heat exchanger air/refrigerant to stop the smallest of fluff and/or fibers. Typically, this additional filter element is placed in the element in the form of a drawer, which is located below the rotating drum can be extended from the housing to allow the user to clean the filter.
However, despite its high efficiency, this solution complicates the design and is expensive to manufacture, which entails all of the disadvantages associated with production costs of the dryer.
The objective of the invention is the creation of a domestic clothes dryer with a simple and more effective air filtration system, is able to significantly reduce the cost of dryer sheets.
This problem is solved in a filter element for household dryer for linen under paragraph 1 of the claims, and preferably any of its dependent claims.
Also the problem is solved in household stiltedly underwear under paragraph 10, and preferably any of its dependent claims.
Next described variant embodiment of the invention with reference to the accompanying drawings.
In Fig.1 shows a household tumble dryer containing a filter element according to the invention, the view in the context of remote for clarity parts;
in Fig.2 and 3, a filter element used in the clothes dryer shown in Fig.1, the species in the future.
In Fig.1 shows a wedge-shaped filter element 1 designed for use in a domestic dryer 2 for linen, containing the outer casing 3 preferably in the form of a parallelepiped; a cylindrical rotary drum 4, is designed to accommodate subjected to drying and mounted for axial rotation within the housing 3 opposite the hole 3A for loading/unloading, made in the front panel 3; and a door 5, pivotally mounted on the front panel 3 can be rotated from the open position to the closed position in which the door 5 is fully pressed to the body for closing the openings 3A in the front panel, sealing the rotating drum 4.
In the above example, the rotating drum is mounted horizontally in the housing 3 on the number of support rollers 6, which are mounted in the housing 3 to provide free rotation of the reel 4 around its longitudinal axis L.
Case 3, the rotation is decomposing the drum 4, the door 5 and the supporting rollers 6 are well known in the art and therefore not described in detail.
As shown in Fig.1, the dryer 2 for linen also contains the motor 7 to rotate the reel 4 around its longitudinal axis L within the casing 3 and the heater 8 with closed circuit located in the housing 3 and ensure the passage of hot air with low moisture content through the rotating drum 4 and contained in lingerie for his quick drying.
In particular, the heater 8 with closed circuit provides a gradual stretching of the rotating drum 4 hot air; removing the excess moisture; heated dehydrated air to the desired temperature, usually higher than the temperature of the air exiting the rotating drum 4; and the hot dehydrated air back into the rotating drum 4, in which it flows through underwear for his quick drying.
Thus, the heater 8 provides continuous dehydration and heat the air circulating inside the rotating drum 4, for fast drying clothes inside the drum and essentially contains:
pipe 9 recirculated air mode, both ends of which are attached to the rotating drum from the opposite side;
- electric centrifugal fan 10 or circulation pump another Ty is a, located along the recirculation pipe 9 to create inside the air flow f flowing through the rotating drum 4 and over inside his underwear;
- cooling medium along the recirculation pipe 9 and is made with quick cooling flow f of air coming out of the rotating drum 4, for condensation of excess moisture;
- heating means located along the recirculation pipe 9 to the flow of funds after cooling airflow and quick heating of the flow f of air returning back into the rotating drum 4, providing rapid heating of the air supplied into the rotating drum 4, to a temperature equal to the temperature of the air leaving the drum, or in excess of this temperature.
In this example, the heater 8 preferably contains a heat pump unit 11, is made with the possibility of rapid cooling exiting the rotating drum 4 flow f of air for condensation of excess moisture, and rapid heating of the flow f of air returning back into the rotating drum 4, providing fast heating is included in the rotating drum of the air to a temperature equal to the temperature of the air leaving the drum, or in excess of this rate is the atur.
As shown in Fig.1, the heat pump unit 11 operates in the same manner as a conventional heat pump is able to transfer heat from one fluid medium to another using an intermediate gaseous refrigerant circulating in a closed thermodynamic cycle, thermodynamic laws which are widely known and therefore not described in detail. Heat pump unit 11 contains:
device 12 compression (e.g., adiabatic) refrigerant with an electric actuator, which provides the output pressure and temperature of the refrigerant is higher than the input;
the first heat exchanger 13 "air/refrigerant (cooling unit air flow), which is located along the recirculation pipe 9 downstream preferably, but not necessarily, after the centrifugal fan 10 and provides simultaneous flow through flow f of air from the rotating drum of refrigerant supplied to the inlet device 12 compression. Since the temperature of the refrigerant is lower than the temperature of the air flow f, the refrigerant absorbs heat from the flow f of air, causing condensation of moisture from the flow f of air;
the second heat exchanger 14 "air/refrigerant (heat air flow), which is located along the recirculation pipe 9 downstream after Teploobmennik air/refrigerant and provides simultaneous flow through flow f of air, directed to the rotating drum 4, and the refrigerant from the outlet of the device 12 compression, allowing the refrigerant temperature which exceeds the temperature of the air flow f, to give the heat flow f of air, rapidly heating it to a temperature higher than the temperature of the air leaving the heat exchanger 13 "air/refrigerant, and preferably equal to the temperature of the air leaving the rotating drum 4, or above this temperature;
- throttle valve or similar device 15 expansion of the refrigerant, ensuring the flow of refrigerant from the second heat exchanger 14 "air/refrigerant" to the first heat exchanger 13 "air/refrigerant for rapid expansion as opposed gripping device 12, so that the pressure and temperature of the refrigerant entering the heat exchanger 13 "air/refrigerant", much below the pressure and temperature of the refrigerant leaving the heat exchanger 14 "air/refrigerant". Thus ends closed thermodynamic cycle.
Finally, the heat pump unit 11 includes several connecting pipes, which connect with each other, the cooling unit 12 compression, the heat exchanger 13 "air/refrigerant, the heat exchanger 14 "air/refrigerant and the device 15 expansion of the refrigerant, forming a closed loop, allowing the refrigerant out of the device is 12 compression and consistently flow through the heat exchanger 14, the device 15 expansion of the refrigerant and the heat exchanger 13 before returning to the entrance of the device 12 compression.
In addition, the coil 8 also includes filtering means located along the pipeline 9 recirculated air stream before the heat exchanger 13 and preferably before the centrifugal fan 10, which eliminates the ingress and the settling of smaller pieces and/or fibers, at least on the heat exchangers 13 and 14.
In particular, as shown in Fig.1, in the example, the end wall 4A of the rotating drum 4 is perforated or, at least, breathable, to ensure the entrance of air into the drum 4. While the outlet pipe 9 of the recirculated air is sealed directly to the end wall 4A of the rotating drum 4. The inlet pipe 9 recirculated air, on the contrary, is located on the ring frame, bounding the hole 3A for loading/unloading, i.e., on the outer edge of the hole 3A for loading/unloading in front panel 3.
In addition, preferably the stream before the heat exchanger 13 is an electric centrifugal fan 10, which is arranged to create a flow f of air flowing along the pipeline 9 recirculated air sequentially through the door 5, the heat exchanger 13, Teploobmennik 14 and the end wall 4A of the rotating drum 4. This filtering means of the heater 8 are located along the pipeline 9 recirculated air flow in front of the centrifugal fan 10.
In particular, in the given example, the door 4 is configured to seal the openings 3A for loading/unloading of the housing 3, but not Sagrada fully inlet pipe 9 recirculated air, which is located on the ring frame, bounding the hole 3A, providing free entrance flow f of air coming from the rotating drum 4, the pipe 9 recirculated air and air flow to the heat pump unit 11. This filtering means of the heater 8 comprises at least one wedge-shaped filter element 1, a removable manner to be inserted into the recess 3b, made in the annular frame, the bounding hole 3a for loading/unloading, namely in the outer edge of the hole 3A for loading/unloading in front panel 3.
As shown in Fig.1, 2 and 3, the filter element 1 includes a support plate 20, made of hard plastic and removable manner to be inserted into the recess 3b formed in the outer edge of the hole 3a for loading/unloading fully closing the recess 3b; and the hollow casing 21, essentially in the form of a container made of hard plastic and protruding from the rear surface and the support plate 20 in the inner space of the initial pipe section 9 recirculated air mode.
The hollow casing 21 made in one piece with the support plate 20 by injection molding and is divided into two complementary flat portion 22A and 22b in the form of shutters are pivotally connected to each other in the lateral line, preferably on the side opposite the base plate 20 so that the hollow casing 21 can be opened like a book (Fig.2).
As shown in Fig.2 and 3, the support plate 20 has a large Central through hole 20A through which air may flow into the hollow casing 21. The bottom wall of each part 22A and 22b of the hollow casing 21 has at least one large through hole 21A, which is completely closed grid, the grid of small cells of appropriate size or a gauze insert 23C to hold the smaller pieces and/or fibers within the hollow casing 21.
As shown in Fig.1, falling into the hollow casing 21 through the opening 20A in the base plate 20, the flow f of air forks and exits the hollow casing 21 through the openings 21A of the two parts 22A and 22b of the hollow casing 21, leaving the fluff and/or fibers within the hollow casing 21.
In the example shown, particularly in Fig.2 and 3, the support plate 20 is essentially rectangular and curved to match the profile of the ring frame, bounding the hole 3A for loading/unloading, namely the outer edge of the hole 3A for zagruzki the/unloading, made in the front panel 3. The opening 20A in the base plate 20 is preferably completely closed bars, made in one piece with the support plate 20.
Preferably the hollow casing 21 can have an essentially V-shaped cross-section, the lower wall of each part 22A and 22b in the form of a leaf has four adjacent through holes 21A, each of which is completely closed by the insert 23 in the form of a grid of fine cells of appropriate size to hold the smaller pieces and/or fibers within the enclosure.
In addition, as shown in Fig.1, 2 and 3, the wedge-shaped filter element 1 contains the main o-ring seal 24, made of thermoplastic rubber or similar thermoplastic elastomer (TPE) (preferably having a shore a Durometer hardness of from 35 to 60 units), which occurred along the entire outer edge of the support plate 20, and two additional o-ring seals 25, made of thermoplastic rubber or similar thermoplastic elastomer (TPE) (preferably having a shore a Durometer hardness of from 35 to 60 units), each of which is applied along the outer connecting flange the relevant part 22A and 22b.
More specifically, in the example, main o-ring seal 24 and/or two additional ring seal 25 is made of Santoprene™, i.e. from a mixture of Termoli is Tolstov EPDM rubber (rubber-based copolymer of ethylene, propylene and diene monomer M-class) and polypropylene having a shore a hardness preferably from 35 to 60 units.
When connecting the outer edge parts 22A and 22b against each other, two o-ring seals 25 are mutually pressing to each other so that they form a completely airtight seal that can stop all kinds of smaller pieces and/or fibers, even the smallest of them.
Similarly, when the support plate 20 is inserted in the recess 3b, o-ring 24 abuts against the side wall of the initial pipe section 9 recirculated air and forms a second fully airtight seal that prevents bypass flow f of air wedge-shaped filter element 1.
The work of the wedge-shaped filter element 1 and the dryer 2 for linen is clear from the above and requires no further explanation.
The obvious advantages associated with the design of wedge-shaped filter element 1: first of all, there is no need to use any additional filtering elements located on the stream after the filter element 1, which is arranged to arrest the slightest smaller pieces and/or fibers, which reduces the cost of the dryer. In addition, due to the applied ring seals 24 and 25 of the filter is 1 element is provided cheaper to manufacture, than the existing filter elements.
Obviously, in a wedge-shaped filter element 1 can be modified in the scope of the present invention.
For example, wedge-shaped filter element 1 can have only one o-ring seal 25, made of thermoplastic rubber or similar thermoplastic elastomer (TPE), which is located along the connecting outer edges of only one of the two parts 22A and 22b. In addition, wedge-shaped filter element 1 may have or just the o-ring 24, or only o-ring seal 25.
