Description

Embodiments of the present invention relate to a clothes dryer.

Conventionally, as a clothes dryer, a drum-type washer-dryer that employs a heat pump has been known. The heat pump is configured by connecting a compressor, a condenser, a throttle device, and an evaporator in a closed loop in order by a refrigerant pipe, of which the evaporator and the condenser as heat exchangers are in a duct constituting a circulation air passage. Is placed in. As a result, the air used for drying the clothes is dehumidified by the evaporator and heated by the condenser.

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

Japanese Unexamined Patent Publication No. 2004-60997

By the way, when the temperature sensor is attached to a predetermined position of the pipe, the lead wire extending from the temperature sensor is bound and fixed to the 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 through the temperature sensor. When the mounting position of the temperature sensor is, for example, a position relatively far from the connection part (root part) of the outlet or inlet of the heat exchanger, the bending moment with respect to the root part of the pipe becomes large, and the bending direction or the twisting direction becomes large. May be relatively stressful.

Therefore, there is a risk of causing deformation of the refrigerant pipe. It is also conceivable that residual stress remains at the base of the refrigerant pipe, causing fatigue failure and the like. In particular, when stress remains in the piping, vibration of the compressor during drying operation, vibration of the dehydration tank during washing operation, especially during dehydration, and vibration during truck transportation cause resonance, etc. Therefore, there is a risk that the piping will be damaged.

Therefore, there is provided a clothes dryer which is provided with a heat pump, can have an appropriate mounting structure for mounting a temperature sensor on a refrigerant pipe, and can suppress stress on the pipe.

The clothes dryer of the present embodiment is configured by connecting a main body having a drying chamber in which clothes are housed, a compressor, a heat exchanger, and a decompression device in a closed loop shape by a refrigerant pipe, and supplies the clothes to the drying chamber.

It is connected to the mouth. As shown in FIG. 4, the blower device 13 includes a centrifugal fan 20 and a motor 21 for driving the centrifugal fan 20 in a fan casing 19. The outlet portion at the upper end of the fan casing 19 is connected to the lower end portion of the air supply duct 16, and the upper end portion 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, the evaporator 23 and the condenser 24 as heat exchangers constituting the heat pump (refrigeration cycle) 22 are provided in the circulation air passage in the main duct 15. They are arranged in order on the left and right in the figure so as to close the. In the present embodiment, as the evaporator 23 and the condenser 24, for example, a fin tube type heat exchanger having a well-known configuration is adopted. As shown in FIG. 4, in the fin tube type heat exchanger (evaporator 23, condenser 24), for example, an aluminum pipe 37 is arranged in a serpentine manner between the two end plates 36, 36, and the pipe 37 thereof is arranged in a serpentine manner. A large number of heat exchange fins 38 are attached to the pipe 37, and the pipe 37 is formed into a slightly oblong rectangular shape as a whole.

As shown in FIG. 3, the heat pump 22 is configured by connecting a compressor 25, a condenser 24, a capillary tube 26 as a decompression device, and an evaporator 23 in a closed loop shape by a refrigerant pipe 27. ing. A required amount of refrigerant is sealed inside the heat pump 22 and circulates in 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 the case 22a (see FIG. 6) which also serves as the main duct 15, and the whole is integrated. It is unitized. This heat pump unit is assembled on a base plate (not shown) at the bottom of the main body 2.

Then, 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 connecting the outlet of the compressor 25 and the condenser 24 as a heat exchanger. A temperature sensor 28 for detecting the above is provided. The mounting structure of the temperature sensor 28 will be described later. Further, a temperature sensor 29 for detecting the temperature of the condenser 24, a temperature sensor 30 for detecting the temperature of the evaporator 23, and a temperature sensor 31 for detecting the temperature of the refrigerant pipe 27 on the inlet side of the compressor 25 are also provided. Further, in the circulation air passage 12, temperature sensors 32 and 33 are provided in the vicinity of the air supply port 10 and the vicinity of the exhaust port 11, respectively. As these temperature sensors 28 to 33, for example, a thermistor is adopted. The detection signals of these temperature sensors are input to the control device 34 (see FIG. 1).

In the heat pump 22 configured as described above, the refrigerant is circulated 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 become a liquid refrigerant. The liquid refrigerant flowing out of the condenser 24 is expanded by the capillary tube 26 to form a mist, and the mist-like refrigerant flows into the evaporator 23. Then, 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. A circulation is performed in which the refrigerant is compressed by the compressor 25 and discharged at high temperature and high pressure.

During the drying operation, the blower device 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 as shown by the arrow A in FIGS. 1 to 3. It reaches the main duct 15 through 18 and the exhaust duct 14, flows through the main duct 15, passes through the evaporator 23 and the condenser 24 in order, then flows into the air supply duct 16, and passes through the air supply port 10 and the hole 4a. The circulation is performed so that the air is supplied into the drum 4. By this air circulation, the air containing a large amount of steam that deprives the clothes in the water tank 3 (drum 4) of moisture is cooled through the evaporator 23 portion in the main duct 15, and the steam is condensed. It is (or sublimated) and dehumidified, and the dehumidified air is heated by passing through the condenser 24 portion to become dry warm air, which is supplied into the drum 4 again and is used for drying clothes.

As shown in FIG. 1, a control device 34 for controlling the overall operation of the washer / dryer 1 is provided in the main body 2. The control device 34 is composed of a computer or the like. During the dry operation, the control device 34 controls the operation of the compressor 25 based on the detected temperatures of the temperature sensors 28 to 33 and the like. Further, an operation panel 35 is provided on the upper part of the front surface of the main body 2 for the user to set and operate the washing / drying operation.

The mounting structure of the temperature sensor 28 with respect to the refrigerant pipe 27 between the outlet portion of the compressor 25 and the condenser 24 in the heat pump 22 of the present embodiment will be described with reference to FIGS. 4 to 6. As shown in FIG. 4, in the present embodiment, the temperature sensor 28 is located and attached to the straight line portion of the refrigerant pipe 27 immediately after going out from the end plate 36 which is the end portion 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, penetrate one (front side) end plate 36 and project to the outside of the end plate 36. Is located in. The protruding dimension of the inlet pipe and the outlet pipe from the end plate 36 is, for example, about 5 to 10 mm.

The end of the refrigerant pipe 27 is connected to the inlet pipe and the outlet pipe from the outside. Specifically, the 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 at one end and connected by welding or the like. The refrigerant pipe 27 has a portion that extends continuously and linearly from the connection portion (root portion) with the inlet pipe, and then extends so as to be curved 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 straight line portion is, for example, about 50 mm.

At this time, in the present embodiment, as shown in FIG. 5, for example, a metal pipe-shaped holder 39 is used to attach the temperature sensor 28 to the refrigerant pipe 27. 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 ends are expanded. The holder 39 is fixed to the straight portion of the refrigerant pipe 27 by, for example, brazing (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 derived 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 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 fixed position F2. The first fixed position F1 and the second fixed position F2 are set, for example, in the case 22a of the heat pump unit, the base plate at the bottom of the main body 1, and the like. The position closer to the temperature sensor 28 is the first fixed position F1, and the position farther away from it (closer to the control device 34) is the second fixed position F2.

Further, in the present embodiment, for example, "Insulok tie (registered trademark)" manufactured by Tyrone Co., Ltd. is adopted as the binding band 42. As shown in FIG. 6, the binding band 42 includes a base portion 42a, a band portion 42b having a base end portion fixed to the base portion 42a, and an arrowhead-shaped protrusion 42c extending downward from the base portion 42a in the figure. And have one. 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, the tip end side of the bound band portion 42b is held by the base portion 42a, and the protrusion portion 42c is fixed (first fixed position F1). ) For example, it is fixed by inserting it into the hole 22b of the case 22a.

Here, as shown by the imaginary line in FIG. 6, the binding band 42 allows a slight deflection in the left-right direction in the figure, for example, a deflection displacement of about 3 mm at the maximum in the fixed portion. In the present embodiment, as shown in FIG. 5, in the fixed state of the lead wire 41 at the first fixed position F1 and the second fixed position F2, among the lead wires 41, up to the temperature sensor 28 and the first fixed position F1. There is a slight slack 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 of a length equal to or more than the maximum deflection amount (3 mm) of the band portion 42b of the binding band 41, for example, about 5 mm. There is slack. In FIG. 5, the line connecting the temperature sensor 28 and the first fixed position F1 with a straight line and the line connecting the first fixed position F1 and the second fixed position F2 with a straight line are shown by imaginary lines. There is. Although not shown, the lead wire 41 is connected to the control device 34 at a portion after the second fixed position F2.

Next, the operation / effect of the washer / dryer 1 having the above configuration will be described. In the washer-dryer 1, for example, when the washing process of washing the clothes in the drum 4 is completed, the drying process is continuously started. In this drying process, the drum 4 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. As a result, as shown by arrows 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 and through the air supply port 10 into the drum 4. Circulation is done.

At this time, in the main duct 15 of the circulation air passage 12, the moist air is cooled and dehumidified by the evaporator 23 portion, and the dehumidified air is heated through the condenser 24 portion and dried at a relatively low temperature. The warm air in the drum 4 causes the clothes in the drum 4 to be efficiently dried with less wrinkles and shrinkage. Then, a temperature sensor 28 is attached to the refrigerant pipe 27 between the outlet portion of the compressor 25 and the inlet of the condenser 24 for the control of the compressor 25 of the heat pump 22 by the control device 34. When the lead wire 41 of the temperature sensor 28 is fixed or connected, the lead wire 41 is pulled (or compressed), and a force acts on the refrigerant pipe 27 via the temperature sensor 28.

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. Be done. Therefore, even if the temperature sensor 28 receives a tensile force (or a compressive force), the distance from the temperature sensor 28 mounting portion of the refrigerant pipe 27 to the root portion is short, so that the bending moment acting on the root portion is generated. It's small. Therefore, 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 dehydration tank drum 4 during the washing operation, especially during the dehydration, and the vibration during truck transportation act. However, it is possible to prevent deformation of the refrigerant pipe 27 and occurrence of fatigue fracture. In particular, in the washer / dryer 1 as in the present embodiment, since the heat pump 22 is integrated as a unit in the case 22a due to its assembleability and the need for waterproofing, the vibration of the compressor 25 is easily transmitted to each part. Since it has a structure, it is of great significance to avoid the above-mentioned trouble by using the mounting structure of the sensor 28 of the present invention.

As described above, according to the present embodiment, in the one provided with the heat pump 22, 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 can be suppressed. Has the excellent effect of being able to. In particular, by setting the temperature sensor 28 mounting portion of the refrigerant pipe 27 to a portion up to 50 mm from the root portion, an excellent effect could be obtained. Further, by mounting the temperature sensor 28 on the straight portion of the refrigerant pipe 27 by using the holder 39, the mounting structure can be relatively simple and the mounting work 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 fixed position F1 and the second fixed position F2 in the main body 2. By fixing the lead wire 41 at a plurality of places in this way, it is not necessary to increase the slack of the lead wire 41 as a whole, and the lead wire 41 is prevented from rubbing against other parts 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 has the maximum amount of deflection of the binding band 42 between the first fixed position F1 and the second fixed position F2 in consideration of the amount of deflection of the binding band 42. A slack having a length of (for example, 3 mm) or more (for example, 5 mm) is provided. As a result, 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 adopting the binding band 42, the work of fixing the lead wire 41 becomes easy.

(2) Second, Third Embodiment, Other Embodiments FIG. 7 shows a second embodiment. This second embodiment differs from the first embodiment in the mounting structure of the temperature sensor 28 to the refrigerant pipe 27. That is, in this second embodiment, the temperature sensor 28 is attached to the refrigerant pipe 27 by using the clip-shaped holder 51 instead of the pipe-shaped holder 39. The holder 51 is made of a metal leaf spring material and has a daruma-shaped cross section (figure 8 shape) as if two cylinders were arranged side by side and integrated. An opening 51a is formed on the side of one of the cylinders, and the opening 51a can be elastically expanded.

When installing the temperature sensor 28, the temperature sensor 28 is inserted into, for example, the cylindrical portion on the back side of the holder 51 to be press-fitted and fixed, and then fitted into the refrigerant pipe 27 from the side while temporarily expanding the opening 51a. Try to get in. Also in this case, the stress on the refrigerant pipe 27 is reduced by mounting the temperature sensor 28 at the straight portion of the refrigerant pipe 27 immediately after going out from the end plate 36 which is the end of the condenser 24. You can finish it. Therefore, similarly to the first embodiment, in the one provided with the heat pump 22, 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 can be suppressed. It has the excellent effect of being able to do. In particular, in this second embodiment, the lead wire 41 is pulled by attaching the temperature sensor 28 to the refrigerant pipe 27 by using a clip-shaped holder 51 whose opening 51a can be elastically expanded. 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. This third embodiment differs from the first embodiment in that the fixed position F3 in the middle 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 to fix the middle portion of the lead wire 41. Of the lead wires 41, a certain amount of slack is provided between the temperature sensor 28 and the fixed position F3, and even a slight slack is provided in the downstream portion of the fixed position F3 (between the connection portion with the control device 34). It is said to have a form.

Even with such a configuration, the temperature sensor 28 is attached to the refrigerant pipe 27 at a position in a straight line portion of the refrigerant pipe 27 immediately after going out from the end plate 36 which is the end of the condenser 24. The stress can be reduced. Therefore, similarly to the first embodiment and the like, in the one provided with the heat pump 22, 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 can be reduced. It is possible to obtain an excellent effect that it can be suppressed.
