Description

  Embodiments described herein relate generally to a clothes dryer.

  2. Description of the Related Art Conventionally, a drum-type washing and drying machine that employs a heat pump is known as a clothes dryer. A heat pump is configured by connecting a compressor, a condenser, a throttle device, and an evaporator in order in a closed loop with refrigerant piping, and among them, an evaporator and a condenser as a heat exchanger are arranged in a duct that constitutes a circulation air passage. Placed in. Thereby, dehumidification with an evaporator and heating with a condenser are performed in air used for drying clothes.

  The heat pump (compressor) is controlled by a control device including a computer. In this case, in order to control the compressor, the refrigerant pipe for constituting the heat pump is for detecting the refrigerant temperature at a predetermined position such as a portion connecting the outlet portion of the compressor and the inlet portion of the condenser. A temperature sensor (thermistor) is provided, and the temperature detection signal is input to the control device. Further, at this time, in order to attach the temperature sensor to the refrigerant pipe, it is necessary to use a holder in a form in which two cylinders, that is, an attachment cylinder part fitted into the pipe and a holding cylinder part into which the temperature sensor is fitted, are connected. It is considered (for example, refer to Patent Document 1).

JP 2004-60997 A

  By the way, when attaching the temperature sensor to a predetermined position of the pipe, a lead wire extending from the temperature sensor is bound and fixed to a predetermined fixing portion or connected to the control device board. When the lead wire is pulled (or compressed) when the lead wire is fixed or connected, a force acts on the pipe via the temperature sensor. For example, if the temperature sensor is installed at a position relatively far from the outlet or inlet connection part (root part) of the heat exchanger, the bending moment with respect to the pipe root part becomes large, and the bending direction or twisting direction May be relatively stressful.

  Therefore, there exists a possibility of causing a deformation | transformation of refrigerant | coolant piping. In addition, it is conceivable to cause fatigue failure due to residual stress remaining in the root portion of the refrigerant pipe. In particular, when the stress remains in the piping, if the vibration of the compressor during the drying operation, the vibration of the dehydration tank during the washing operation, especially during the dehydration, and the vibration during truck transportation, etc., resonance will occur. As a result, the piping may be damaged.

  Accordingly, there is provided a clothes dryer that is provided with a heat pump, can have an appropriate mounting structure for attaching a temperature sensor to a refrigerant pipe, and can suppress the stress of the pipe.

  The clothes dryer of the present embodiment is configured by connecting a main body having a drying chamber in which clothes are stored, a compressor, a heat exchanger, and a pressure reducing device in a closed loop shape with a refrigerant pipe, and supplying the same into the drying chamber. A heat pump for generating low humidity, high temperature dry air, and a temperature sensor for detecting the temperature of the refrigerant pipe for driving and controlling the heat pump, and the temperature sensor includes: It is attached to the straight part immediately after coming out from the end of the heat exchanger.

As shown in FIG. 1, a filter device 18 that houses a lint filter (not shown) is connected to an upper portion of the exhaust port 11 of the water tank 3 via a bellows-like connection duct 17. As shown also in FIG. 2, the upper end of the exhaust duct 14 is connected to the outlet of the filter device 18. The lower end of the exhaust duct 14 is connected to the end of the main duct 15 on the entrance side (right side, left side in FIG. 2).

  The main duct 15 is arranged extending in the left-right direction on the bottom rear side in the main body 2, and the outlet side (left side, right side in FIG. 2) end of the main duct 15 sucks the front part of the fan casing 19 of the blower 13. Connected to the mouth. As shown in FIG. 4, the blower 13 includes a fan casing 19 provided with a centrifugal fan 20 and a motor 21 that drives the centrifugal fan 20. The outlet of the upper end of the fan casing 19 is connected to the lower end of the air supply duct 16, and the upper end of the air supply duct 16 is connected to the air supply port 10 of the water tank 3.

  As shown in FIGS. 2 to 4, in the main duct 15, an evaporator 23 and a condenser 24, which constitute a heat pump (refrigeration cycle) 22, as heat exchangers, are circulated in the main duct 15. Are arranged in order from left to right in the figure. In this embodiment, as the evaporator 23 and the condenser 24, for example, a fin tube type heat exchanger having a well-known configuration is employed. As shown in FIG. 4, the fin tube type heat exchanger (evaporator 23, condenser 24) arranges, for example, an aluminum pipe 37 in a meandering manner between the two end plates 36, 36. A large number of heat exchanging fins 38 are attached to the pipe 37, and as a whole, it is configured in a slightly horizontally long rectangular parallelepiped shape.

  As shown in FIG. 3, the heat pump 22 is configured by connecting a compressor 25, the condenser 24, a capillary tube 26 serving as a decompression device, and the evaporator 23 in a closed loop by a refrigerant pipe 27. ing. A required amount of refrigerant is sealed inside the heat pump 22 and circulates through the refrigerant pipe 27. At this time, although not shown in detail, each component constituting the heat pump 22 including the compressor 25 is assembled on a common base in a case 22a (see FIG. 6) that also serves as the main duct 15, and is integrated as a whole. It has become a unit. The heat pump unit is assembled on a base plate (not shown) at the bottom of the main body 2.

  As schematically shown in FIG. 3, in the heat pump 22, the temperature of the refrigerant pipe 27 (refrigerant) is connected to the refrigerant pipe 27 portion that connects the outlet of the compressor 25 and the condenser 24 as a heat exchanger. A temperature sensor 28 is provided for detecting. The mounting structure of the temperature sensor 28 will be described later. A temperature sensor 29 that detects the temperature of the condenser 24, a temperature sensor 30 that detects the temperature of the evaporator 23, and a temperature sensor 31 that detects the temperature of the refrigerant pipe 27 on the inlet side of the compressor 25 are also provided. Furthermore, temperature sensors 32 and 33 are also provided in the vicinity of the air supply port 10 and the exhaust port 11 in the circulation air passage 12, respectively. As these temperature sensors 28 to 33, for example, a thermistor is employed. Detection signals from these temperature sensors are input to the control device 34 (see FIG. 1).

  In the heat pump 22 configured as described above, the refrigerant circulates in the direction indicated by the arrow B in FIG. 3 by driving the compressor 25 during the drying operation. That is, the gaseous refrigerant discharged from the compressor 25 flows into the condenser 24 and is condensed by heat exchange in the condenser 24 to be a liquid refrigerant. The liquid refrigerant that has flowed out of the condenser 24 is expanded by the capillary tube 26 to form a mist, and the mist refrigerant flows into the evaporator 23. In the evaporator 23, the refrigerant is vaporized by heat exchange with the outside air, and the gaseous refrigerant is returned to the compressor 25. Circulation is performed in which the refrigerant is compressed by the compressor 25 and discharged at a high temperature and high pressure.

  During the drying operation, the air blower 13 is driven together with the drive of the heat pump 22, so that the air in the water tank 3 (drum 4) is filtered from the exhaust port 11 through the filter 11 as shown by the arrow A in FIGS. 1 to 3. 18 and the exhaust duct 14 to the main duct 15, flow in the main duct 15, pass through the evaporator 23 and the condenser 24 in order, then flow into the air supply duct 16, and pass through the air supply port 10 and the hole 4 a. Then, circulation is performed such that the air is supplied into the drum 4. Due to the circulation of the air, the moisture containing moisture from the clothes in the water tank 3 (drum 4) is cooled through the evaporator 23 portion in the main duct 15 to condense the steam. (Or sublimation) and dehumidified, and the dehumidified air is heated by passing through the condenser 24 portion to become dry warm air, and is supplied again into the drum 4 to be used for drying clothes.

  As shown in FIG. 1, a control device 34 for controlling the overall operation of the washing / drying machine 1 is provided in the main body 2. The control device 34 is constituted by a computer or the like. During the drying operation, the control device 34 controls the operation of the compressor 25 based on the temperature detected by the temperature sensors 28-33. An operation panel 35 is provided on the front upper portion of the main body 2 for the user to perform settings and operations related to the washing / drying operation.

  Now, an attachment structure of the temperature sensor 28 to the refrigerant pipe 27 between the outlet of the compressor 25 and the condenser 24 in the heat pump 22 of the present embodiment will be described with reference to FIGS. As shown in FIG. 4, in the present embodiment, the temperature sensor 28 is mounted at a position in a straight line portion of the refrigerant pipe 27 immediately after exiting from the end plate 36 that is the end of the condenser 24. ing. In this case, although not shown in detail, in the condenser 24, the inlet pipe and the outlet pipe, which are both ends of the pipe 37, pass through one (front side) end plate 36 and protrude outside the end plate 36. Is arranged. The protrusion dimension from the end plate 36 of an inlet pipe and an outlet pipe is about 5-10 mm, for example.

  The ends of the refrigerant pipe 27 are connected to the inlet pipe and the outlet pipe from the outside. Specifically, a portion of the refrigerant pipe 27 that connects the outlet portion of the compressor 25 and the condenser 24 is fitted to the inlet pipe from the outside and connected by welding or the like. The refrigerant pipe 27 has a portion extending continuously and linearly from the connection portion (root portion) with the inlet pipe, and thereafter extends so as to be bent and is connected to the outlet portion of the compressor 25. Specifically, the size (length dimension) of the temperature sensor 28 is about 25 mm, while the length dimension of the linear portion is about 50 mm, for example.

  At this time, in this embodiment, as shown in FIG. 5, when attaching the temperature sensor 28 to the refrigerant pipe 27, for example, a metal pipe-shaped holder 39 is used. The holder 39 has a cylindrical pipe shape having a length substantially equal to that of the temperature sensor 28 and has a shape in which both end portions are expanded. The holder 39 is fixed to a straight portion of the refrigerant pipe 27 by, for example, brazing (a wax is indicated by reference numeral 40), and the temperature sensor 28 is press-fitted into the holder 39 and fixed.

  The lead wire 41 led out from the temperature sensor 28 is connected to the substrate of the control device 34, but as shown in FIG. 5, the middle portion of the lead wire 41 is the first fixed in the main body 1. It is fixed by the binding band 42 at at least two positions, the position F1 and the second fixing position F2. The first fixed position F1 and the second fixed position F2 are set, for example, on the case 22a of the heat pump unit, the base plate at the bottom of the main body 1, or the like. A position close to the temperature sensor 28 is defined as a first fixed position F1, and a position further away (closer to the control device 34) is defined as a second fixed position F2.

  In the present embodiment, for example, “Insulok tie (registered trademark)” manufactured by Tyrone Co., Ltd. is employed as the binding band 42. As shown in FIG. 6, the binding band 42 includes a base portion 42a, a band portion 42b whose base end portion is fixed to the base portion 42a, and an arrowhead-shaped protrusion 42c extending downward from the base portion 42a in the drawing. Are integrated. Then, the band portion 42b is bound so as to be wound around the outer periphery of the lead wire 41 in a ring shape, and the leading end side of the bound band portion 42b is held by the base portion 42a. For example, it is fixed by being inserted into the hole 22b of the case 22a.

  Here, as shown by an imaginary line in FIG. 6, the binding band 42 is allowed to be slightly deflected in the left-right direction in the drawing, for example, about 3 mm at maximum. In the present embodiment, as shown in FIG. 5, the lead wire 41 is fixed to the temperature sensor 28 and the first fixing position F1 in the first fixing position F1 and the second fixing position F2. There is a slight sagging between them. At the same time, between the first fixed position F1 and the second fixed position F2, the lead wire 41 has a slack with a length equal to or greater than the maximum deflection amount (3 mm) of the band portion 42b of the binding band 41, for example, about 5 mm. Sagging is provided. In FIG. 5, a line connecting the temperature sensor 28 and the first fixed position F1 with a straight line and a line connecting the first fixed position F1 and the second fixed position F2 with a straight line are shown by imaginary lines. Yes. Although not shown, the lead wire 41 is connected to the control device 34 at the portion after the second fixed position F2.

  Next, the operation and effect of the washing / drying machine 1 configured as described above will be described. In the washing / drying machine 1, for example, when the washing process for washing the clothes in the drum 4 is completed, the drying process is continuously started. In this drying process, the drum 7 is rotated in both forward and reverse directions at a low speed by driving the motor 7, the compressor 25 is started, and the heat pump 22 is operated. At the same time, the blower 13 is driven. Thereby, as indicated by an arrow A in FIGS. 1 and 3, the air in the water tank 3 (drum 4) is supplied from the exhaust port 11 through the circulation air passage 12 to the air supply port 10 and into the drum 4. Circulation is performed.

  At this time, in the main duct 15 of the circulation air passage 12, the air containing moisture is cooled and dehumidified in the evaporator 23 portion, and the dehumidified air is heated through the condenser 24 portion and dried to a relatively low temperature. As a result, the clothes in the drum 4 are dried efficiently with little wrinkling and shrinkage. For the control of the compressor 25 of the heat pump 22 by the control device 34, a temperature sensor 28 is attached to the refrigerant pipe 27 between the outlet of the compressor 25 and the inlet of the condenser 24. When the lead wire 41 of the temperature sensor 28 is fixed or connected, a force acts on the refrigerant pipe 27 via the temperature sensor 28 as the lead wire 41 is pulled (or compressed).

  However, in the present embodiment, the temperature sensor 28 is attached to the straight line portion of the refrigerant pipe 27 immediately after going out from the end portion (end plate 36), which is a position close to the inlet portion of the condenser 24, that is, the root portion. It is done. Therefore, even if the temperature sensor 28 receives a tensile force (or compressive force), since the distance from the temperature sensor 28 mounting portion of the refrigerant pipe 27 to the root portion is short, the bending moment acting on the root portion is small. It's small. Accordingly, the stress on the refrigerant pipe 27 can be reduced, and the vibration of the compressor 25 during the drying operation, the vibration of the dewatering tub drum 4 during the washing operation, particularly during the dehydration, and further the vibration during the truck transportation, etc. act. However, the deformation of the refrigerant pipe 27 and the occurrence of fatigue failure can be prevented in advance. In particular, in the washer / dryer 1 as in the present embodiment, the heat pump 22 is integrated as a unit in the case 22a because of its assemblability and the necessity of waterproofing. Therefore, the vibration of the compressor 25 is easily transmitted to each part. Because of the structure, it is significant to avoid the occurrence of the above-mentioned problems by adopting the sensor 28 mounting structure of the present invention.

  Thus, according to the present embodiment, the heat pump 22 is provided, and the mounting structure when the temperature sensor 28 is attached to the refrigerant pipe 27 can be made appropriate, and the stress of the refrigerant pipe 27 is suppressed. There is an excellent effect that becomes possible. In particular, when the temperature sensor 28 mounting portion of the refrigerant pipe 27 is a portion from the root portion to 50 mm, an excellent effect can be obtained. In addition, since the temperature sensor 28 is attached to the linear portion of the refrigerant pipe 27 using the holder 39, the attachment structure can be relatively simple and the attachment operation can be facilitated.

  At this time, in the present embodiment, the lead wire 41 of the temperature sensor 28 is fixed by the binding band 42 at at least two positions of the first fixing position F1 and the second fixing position F2 in the main body 2. In this way, by fixing the lead wire 41 at a plurality of positions, it is not necessary to increase the slack of the lead wire 41 as a whole, and the lead wire 41 is suppressed while preventing problems such as rubbing with other portions of the lead wire 41. It is possible to prevent the tensile force of the wire 41 from acting on the temperature sensor 28 and thus the refrigerant pipe 27.

  In particular, in the present embodiment, the lead wire 41 of the temperature sensor 28 takes into account the amount of deflection of the binding band 42, and the maximum amount of deflection of the binding band 42 between the first fixed position F1 and the second fixed position F2 ( For example, a slack with a length of 3 mm or more (for example, 5 mm) is provided. Thereby, it is possible to effectively prevent problems such as rubbing of the lead wire 41 while reliably preventing the lead wire 41 from being pulled. By employing the binding band 42, the lead wire 41 can be fixed easily.

(2) Second and Third Embodiments and Other Embodiments FIG. 7 shows a second embodiment. The second embodiment is different from the first embodiment in the structure for attaching the temperature sensor 28 to the refrigerant pipe 27. That is, in the second embodiment, a configuration in which the temperature sensor 28 is attached to the refrigerant pipe 27 using a clip-shaped holder 51 instead of the pipe-shaped holder 39 is employed. The holder 51 is formed from a metal leaf spring material so that two cylinders are arranged side by side and integrated into a daruma section (8-shaped). An opening 51a is formed on the side of one cylinder, and the opening 51a can be elastically expanded.

  When the temperature sensor 28 is attached, the temperature sensor 28 is inserted into a cylindrical portion on the back side of the holder 51, for example, and is press-fitted and fixed. Then, the opening 51a is temporarily expanded, and then fitted into the refrigerant pipe 27 from the side. To be included. Also in this case, the stress on the refrigerant pipe 27 is reduced by attaching the temperature sensor 28 to a position in a straight line portion of the refrigerant pipe 27 immediately after exiting from the end plate 36 that is the end of the condenser 24. I can finish it. Therefore, similarly to the first embodiment, the heat pump 22 is provided, and the mounting structure when the temperature sensor 28 is attached to the refrigerant pipe 27 can be made appropriate, and the stress of the refrigerant pipe 27 is suppressed. There is an excellent effect that it becomes possible to do. In particular, in the second embodiment, the temperature sensor 28 is attached to the refrigerant pipe 27 by using the clip-shaped holder 51 whose opening 51a can be elastically expanded, so that the lead wire 41 is pulled. Even if vibration is transmitted, the holder 51 can be appropriately deformed to reduce the transmission of force to the pipe, and the stress to the refrigerant pipe 27 can be further suppressed.

  FIG. 8 shows a third embodiment. The third embodiment is different from the first embodiment in that the fixing position F3 in the middle portion of the lead wire 41 of the temperature sensor 28 is set to one place. In this case, the binding band 42 is also used for fixing the middle portion of the lead wire 41. Among the lead wires 41, a certain amount of slack is provided between the temperature sensor 28 and the fixed position F3, and a slight slack is also provided at the downstream portion of the fixed position F3 (up to the connection portion with the control device 34). It is assumed to have a form.

  Even in such a configuration, the temperature sensor 28 is attached to the refrigerant pipe 27 by a configuration in which the temperature sensor 28 is attached to the straight line portion of the refrigerant pipe 27 immediately after exiting from the end plate 36 that is the end of the condenser 24. Stress can be reduced. Therefore, as in the first embodiment, the heat pump 22 is provided, and the mounting structure when the temperature sensor 28 is attached to the refrigerant pipe 27 can be made appropriate. The excellent effect that it becomes possible to suppress can be acquired.

  In each of the above-described embodiments, the present invention is applied to a drum-type (horizontal shaft type) washing / drying machine, but the so-called vertical washing / drying machine in which the axial direction of the water tub and the rotating tub is directed vertically. It is also possible to apply. Further, the present invention can be applied to a clothes dryer for drying only without a washing function. And about the structure of a heat pump, for example, the structure of a circulation air path, it is good also as a structure which arrange | positions a main duct in the upper part in a main body. A throttle valve or the like can also be employed as the decompression device.
