Description

  The present invention relates to a washing machine.

  In the drum-type washing and drying machine, an outer tub that stores water in a casing is supported by vibration isolation, and a drum that is a washing and dewatering tub is rotatably supported in the outer tub via a motor. In addition, a drying unit, a water supply unit, a control unit, and the like are disposed in the casing (hereinafter, components supported by the casing by means different from the outer tub, such as a drying unit, a water supply unit, or a control unit) Are called individual units). Each individual unit is fixed to the housing in a state where electric parts, mechanical parts, and the like are integrated.

  During the dehydration process, the laundry stored in the drum is dehydrated by rotating the drum at a high speed. At this time, if the laundry in the drum is unevenly distributed, an excitation force is generated due to an unbalance of centrifugal force. This excitation force may be transmitted from the drum to the outer tub, and further from the outer tub to the housing through the vibration-proof support structure, resulting in vibration and noise. In particular, the case vibration is easily affected by the strength of the installation floor surface on which the case is installed. This is because the housing is elastically supported on the ground having sufficient rigidity via the floor of the building. For example, when the floor strength is low, the natural frequency of the housing vibration is low, so the dehydration rotation speed is close to the resonance rotation speed of the housing vibration, or passes the resonance rotation speed of the housing vibration, or the housing. The vibration tends to increase by matching the resonance rotational speed of the vibration.

  As described above, since the vibration of the casing is affected by the installation floor surface, as a conventional technique, in Patent Document 1, a rotating tub for washing and dewatering is provided in a water tank to form a tank body. In the washing machine in which the outer casing is elastically supported, the aquarium vibration detection means for detecting the vibration of the aquarium, and the vibration detection for the aquarium provided in the outer casing for detecting the vibration of the outer casing. A vibration detection means for the outer box different from the means, and the rotation of the rotating tub during dehydration is controlled by changing to a pattern corresponding to the detected vibration of both the vibration detection means for the water tank and the outer box. Therefore, the vibration of both the water tank and the outer box is detected, and the rotation of the rotating tank is controlled by a pattern according to the detected vibration, so that the outer box vibrates more than the water tank or the water tank The rotation of the rotating tank is prevented while preventing significant vibration. It can be raised to the minute, is described as.

  Patent Document 2 discloses a washing machine including a driving unit that rotationally drives a washing / dehydrating tub and a detection unit that detects vibration of the casing, and the casing resonates based on the output of the detection unit. An installation floor surface in each household by controlling the drive means based on the measured casing resonance rotation speed, and comprising means for measuring body resonance rotation speed and means for recording the casing rotation speed According to the state, it is described that it is possible to perform a dehydrating operation avoiding the casing resonance rotational speed.

  The case not only vibrates with the force transmitted from the outer tub through the anti-vibration support structure, but also vibrates the individual unit fixed inside the case. At this time, the individual unit is elastically deformed at a fixing portion with respect to the casing and vibrates in a mode different from that of the casing. The magnitude of this vibration varies depending on the installation situation and the operating situation under the influence of the hardness of the installation floor and the uneven distribution of the laundry, similarly to the case vibration that is the excitation source. In addition, since the vibration of the individual unit includes an electric component or a mechanical component having a large mass inside, the natural frequency is lower than that of the reinforcing member constituting the casing. Therefore, when dehydrating at a high rotation speed, the dehydration rotation speed is close to the resonance rotation speed of the individual unit, passes through the resonance rotation speed of the individual unit, or matches the resonance rotation speed of the individual unit. Vibration may be excessive.

  However, the techniques disclosed in Patent Document 1 and Patent Document 2 detect vibrations of the outer tub and the casing, and cannot detect vibrations of individual units disposed in the casing. This is because the individual unit has a vibration mode different from that of the casing and the outer tub, and further, the vibration is changed due to the influence of the operation state such as the hardness of the installation floor and the state of the laundry, so that the prediction is made in advance. Because it is difficult. Therefore, the techniques disclosed in Patent Document 1 and Patent Document 2 have a problem that dehydration is continued as it is even when the vibration of the individual unit becomes excessive.

  Therefore, the present invention prevents rotation of the washing and dewatering tub while preventing excessive vibration of the individual unit from generating noise, or preventing the individual unit from coming off and dropping off due to the excessive vibration. A washing machine capable of raising the height is provided.

  In order to solve the above-described problems, a washing machine of the present invention includes a washing and dewatering tub that is rotatably provided in an outer tub that stores water, a motor that rotationally drives the washing and dewatering tub, and a housing that forms an outer shell. In a washing machine comprising a body, a water supply unit for supplying water into the outer tub, and a control unit for controlling the motor and the water supply unit, a drying unit for drying the air in the outer tub, the water supply unit , At least one of the control unit is supported by the casing by means different from the outer tub, and is supported by the housing by means different from the outer tub, the drying unit, the water supply unit, or the A washing machine, wherein the control unit is provided with vibration detecting means.

  According to the present invention, since the vibration detection means is provided in the individual unit, even if the casing vibration, which is the excitation source of the individual unit, differs depending on the operation due to the distribution of the installation floor and the unevenness of clothing, the individual unit It is possible to provide a washing machine that increases the rotational speed of the washing and dewatering tank while preventing excessive vibration of the washing and dehydrating tank.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate. In the following, a drum type washing and drying machine will be described as an example.

FIG. 1 is a front view of a drum-type washing / drying machine according to the present embodiment. As shown in FIG. 1, the drum type washing / drying machine according to the present embodiment includes a casing 1 that forms the outer shell thereof. As shown in the exploded view of the case 1 shown in FIG. 2, the case 1 has a front reinforcing plate 1g, a right side plate 1d, a left side plate 1e, a rear reinforcing plate 1i, A reinforcing plate 1h and a back reinforcing plate 1f are provided, and a front cover 1a and a top cover 1b are provided as external members from the outside. That is, the casing 1 is supported by the casing 1 by means different from the outer tub 23 such as the outer tub 23 (see FIG. 3) and the individual unit (the control unit 4 or the water supply unit 10 or the drying unit 40 shown in FIG. 3). In addition, it has a role as an appearance member that can be directly seen by the user. Since the housing 1 only needs to support the outer tub 23 and the individual unit, when the front cover 1a and the upper cover 1b have sufficient strength, the front reinforcing plate 1g, the rear reinforcing plate 1i, and the upper reinforcing plate 1h are used. Such a reinforcing member is not always necessary.

  A front cover 1a on the front surface of the housing 1 is provided with a loading port 2a for putting laundry in and out at a substantially central position, and a door 2 is provided at the loading port 2a so as to be freely opened and closed. In the upper part of the housing 1, a detergent case 12 for supplying detergent, an operation panel 3 for controlling the operation method, and a water supply port 10a for supplying water from the water supply are provided. The operation panel 3 includes a start switch 3b for turning on / off the power, a controller 3c for determining an operation method, and a display unit 3a for displaying an operation state, for sequentially controlling the operation. The control unit 4 (see FIG. 3) is electrically connected. The base 1c at the lower part of the housing 1 is elastically supported with respect to the installation floor surface by supporting legs 5 provided at the four corners of the lower surface.

  FIG. 3 is a schematic right side view showing the internal structure of the drum-type washing and drying machine. However, the front cover 1a, the top cover 1b, the back reinforcing plate 1f, and the right side plate 1d are omitted for explanation. As shown in FIG. 3, an outer tub 23 for storing water is supported in a vibration-proof manner via a suspension 24 and an auxiliary spring 25 inside the housing 1, and includes a drum 21 for storing laundry. . The drum 21 is formed in a substantially cylindrical shape having a back surface, and includes a large number of through holes 21c on the cylindrical portion and the back surface, a fluid balancer 21d in which liquid is sealed on the front surface, and a plurality of lifters 21b on the inner peripheral wall. The drum 21 is connected to a motor 22 on the rear surface of the outer tub 23 via a shaft 22a. The motor 22 rotates the drum 21 forward (clockwise when the washing machine is viewed from the front) and reverse (removes the washing machine from the front). Driven in both directions (counterclockwise as viewed). The drum 21 is arranged such that its rotation axis is inclined horizontally or downward from the front to the back.

  The outer tub 23 is formed in a substantially cylindrical shape having a front surface and a back surface, and the front surface has an opening 23a for taking in and out the laundry. By opening the door 2 (see FIG. 2), the housing 1 The input port 2a communicates with the inside of the drum 21 so that the laundry can be taken in and out of the drum 21. Further, a space between the inlet 2a and the outer tub 23a is sealed with a bellows 26 that can be elastically deformed. Below the outer tub 23, an outer tub vibration detecting means 27 for detecting the vibration of the outer tub 23 is provided.

  The housing 1 includes individual units such as a control unit 4, a water supply unit 10, and a drying unit 40. Unlike the outer tub 23 supported by the suspension 24, the individual unit is fixed to the housing 1 with screws or bolts, or fixed with screws or bolts through a vibration-proof member such as rubber, Arranged in the housing 1. The individual unit is composed of a plurality of parts such as an electrical part and a mechanism part, and the plurality of constituent parts are connected to each other, so that the individual unit can be removed from the housing 1 as a unit. That is, an assembly of parts that can be removed from the housing 1 collectively is an individual unit. Note that at least one individual unit is disposed in the housing 1.

  Here, the control unit 4, which is one of the individual units, is fixed to the base 1c and is electrically connected to the display panel 3, the motor 22, and the like. The control unit 4 is not necessarily fixed to the base 1c. For example, the control unit 4 is fixed to the water supply unit 40 which is an individual unit different from the control unit 4, thereby shortening the distance of electrical connection. If it is possible, the influence of disturbances such as electrical noise and resistance can be reduced.

  Moreover, the water supply unit 10 which is one of the individual units includes a water supply port 10a for connection with a water supply hose extending from a water tap, a water supply valve 10b for supplying or stopping water in the outer tub 23, and water supplied. It is comprised from the water supply path | route 10c for guide | inducing to the outer tank 23, the detergent case 12 provided in the middle of the water supply path | route 10c, the water level detection means 10d for detecting the water level in the outer tank 23, etc. These components are installed on a resin mounting member, and a fixing portion to the housing 1 is a resin member.

  The drying unit 40, which is one of the individual units, includes a dehumidification duct 40a for dehumidifying humid air, a lint filter 40b for collecting lint, a fan 40c for sending air into the outer tub 23, A heater 40d for warming air, a ventilation path 40e for guiding the air sent from the fan 40c into the outer tub 23, and bellows hoses 40f and 40g for connecting the individual unit and the outer tub 23. . Each of these components is connected and fixed with screws or bolts, and a fixing portion with the housing 1 is a resin member.

  Here, FIG. 4 shows a model of the vibration system of the drum type washing and drying machine by a spring. As shown in FIG. 4, when the drum 21 rotates in the dehydration process, if the clothes C are unevenly distributed, an exciting force (indicated by an arrow) is generated due to an unbalanced centrifugal force. The vibration force causes the drum 21 and the outer tub 23 to vibrate integrally, and further vibrates the casing 1 supported on the ground G by the floor F and the support leg 5 via the auxiliary spring 25 and the suspension 24. In addition, the casing 1 serves as a vibration force to vibrate individual units such as the control unit 4, the water supply unit 10, and the drying unit 40. The spring constant between the individual unit and the housing 1 is affected by the fixing method between them. For example, if the fixing portion between the individual unit and the housing 1 is a metal member having high rigidity, the deformation of the fixing portion is reduced. Since it is small, the spring constant is large. On the contrary, if one or both of the fixing portions of the individual unit and the housing 1 is a resin material having low rigidity, the spring constant is small because the fixing portion elastically deforms. In addition, when the vibration isolator for vibration insulation is interposed in the fixed part of the individual unit and the housing 1, the spring constant is further reduced.

  In such a vibration model, as shown in FIG. 4, since it is considered as a one-degree-of-freedom vibration system in which the fixing portion between the individual unit and the housing 1 is a spring, the fixing portion with the housing 1 has low rigidity. Although it is resinous, it has an electrical component and a mechanical component with a large mass, so the resonance rotational speed tends to be low. Therefore, if an attempt is made to increase the dehydration rotation speed in order to dehydrate more water, the dehydration rotation speed is close to, passes through, or matches the resonance rotation speed of the individual unit. Vibration tends to be excessive.

  Further, the vibration of the individual unit is affected by the magnitude of the composite spring constant from the support leg 5 to the ground G, the amount of laundry, and the imbalance. This is because the vibration of the individual unit is affected by the vibration of the casing 1 that is the excitation source. For example, when a wooden house or a plastic waterproof pan is laid, the combined spring constant from the support leg 5 to the ground G decreases, and the vibration of the housing 1 increases, so that the vibration of the individual unit also increases. Similarly, when the distribution of the laundry is largely biased, the vibration of the outer tub 23 increases, so that the vibration of the housing 1 also increases and the vibration of the individual unit increases. On the contrary, when the composite spring constant from the support leg 5 to the ground G is large in a reinforced concrete house, or when the uneven distribution of the laundry is small, the vibration of the individual unit is small.

  As described above, the individual unit having different vibrations depending on the installation state and the operation state includes individual unit vibration detection means 50a for detecting the vibration of one or more of the individual units. The individual unit vibration detecting means 50a is electrically connected to the control unit 4 by wire. In the present embodiment, separate from the outer tank vibration detection means 27, the individual unit vibration detection means 50 a for detecting the vibration of the drying unit 40 is provided in the drying unit 40. Since the drying unit 40 is provided with a fan 40c having a drive unit, for example, vibration of the fan 40c can also be detected. Further, even if the individual unit vibration detecting means 50a is fastened together with the drying unit 40 to the housing 1, the same operation and effect can be obtained. The individual unit vibration detecting means 50a may be of a type that detects acceleration or a type that detects strain when the individual unit a vibrates. Further, the signal transmission / reception from the individual unit vibration detection means 50a to the control unit 4 may be a method in which the individual unit vibration detection means 50a has a generator and supplies power itself and transmits / receives it wirelessly.

  The operation of the above configuration will be described. When the door 2 is opened, the laundry is put into the drum 21 and a predetermined amount of detergent is put into the detergent container 12, and then the operation is started, the washing process is executed first. In the washing process, water supplied from the water supply port 10a is supplied to the detergent container 12 through the water supply path 10c when the water supply valve 10b is opened, and enters the outer tub 23 together with the detergent. After this operation is performed for a predetermined time until the water level detecting means 10d reaches a predetermined water level, a washing operation in which the drum 21 repeats normal rotation, stop, reverse rotation, and stop is performed for a predetermined time. At this time, the laundry accommodated in the drum 21 is lifted in the rotational direction by the lifter 21b provided on the inner peripheral wall of the drum 21, and the stirring operation of dropping from the raised height position is repeated. The action of tapping is activated and washing is performed.

  When this operation is performed for a predetermined time and the washing process is completed, the drain valve 13 a is opened, and the water in the outer tub 23 is drained through the drain hose 13. Then, the process proceeds to the next dehydration step, the drum 21 is rotated, and after reaching a predetermined rotational speed (for example, 900 r / min), the drum 21 is rotated for a predetermined time, thereby dehydrating water contained in the laundry. In the dehydration step, the vibration of the outer tub 23 is detected by the outer tub vibration detecting means 27, and the vibration of the individual unit is detected by the individual unit vibration detecting means 50a. The rotational speed of the drum 21 is controlled while preventing occurrence of the above.

  Here, a method for controlling the rotational speed of the drum 21 in the dehydration step will be described with reference to FIG. First, after dehydration is started in step S101, the rotational speed of the drum 21 is increased (step S102). At this time, the detected vibration of the outer tank vibration detecting means 27 of the outer tank 23 is compared with a predetermined value in step S103, and if the detected vibration is smaller than the predetermined value, a high-speed rotation range (for example, from 900 r / min). The rotational speed of the drum 21 is increased up to the range of the maximum dewatering rotational speed (step S108). Conversely, if the detected vibration is greater than or equal to a predetermined value, the rotation speed of the drum 21 is decreased until the rotation speed of the drum 21 reaches the predetermined rotation speed (steps S109 and S110), and N is less than or equal to the predetermined value. (Step S111) A loosening operation for correcting the bias of the laundry is performed (Step S112). This unraveling operation is intended to eliminate unevenness and entanglement of the laundry by reversing the drum 21 at a rotational speed at which a part of the laundry does not stick to the inner peripheral wall of the drum 21. As described above, while monitoring the detected vibration of the outer tub 23, the bias of the laundry can be corrected as appropriate, and the rotation speed of the drum 21 can be increased. If N is greater than the predetermined number of times, it is determined that it is difficult to correct the unevenness of the laundry, and the dehydration is interrupted (step S114).

  In the high speed dewatering region, the rotational speed of the drum 21 is further increased (step S105), and the rotational speed of the drum 21 is made constant at the stage where the target rotational speed is reached in step S108 (steps S118 and S119). At this time, if the detected vibration of the outer tank vibration detecting means 27 becomes greater than or equal to a predetermined value in step S106, or if the detected vibration of the individual unit vibration detecting means 50a is greater than or equal to the predetermined value in step S107, the drum 21 The rotational speed is lowered (step S115). Then, in step S116, when the detected vibration of the outer tank vibration detecting means 27 becomes smaller than a predetermined value, and in step S117, the detected vibration of the individual unit vibration detecting means 50a becomes smaller than the predetermined value, the drum 21 Is kept constant (step S118). Then, after the drum 21 is rotated at a constant speed for a predetermined time in step S119, dehydration is completed (step S110).

  According to the control described above, as the rotational speed of the drum 21 increases, the individual unit approaches the resonance rotational speed, and the vibration also increases. However, before it becomes excessive, the rotational speed of the drum 21 is increased. In order to stop the ascent, the vibration of the individual unit can be prevented from becoming excessive. At the same time, the rotation speed of the drum 21 can be continuously increased while preventing the vibration of the outer tank 23 from being excessively increased by the vibration detection means 27 for the outer tank. Further, in the above control, when the vibration of the individual unit exceeds a predetermined value, the rotation speed of the drum 21 is decreased, but when the resonance rotation speed of the individual unit and the rotation speed at which the vibration becomes large are known in advance, Conversely, the rotational speed of the drum 21 may be increased until the resonance rotational speed is exceeded. According to this, dehydration can be performed at a higher rotational speed while preventing the vibration of the individual units affected by the uneven distribution of the installation floor and the laundry from being excessive for a long time. In addition, as a method of recording in advance the resonance rotational speed of the individual unit and the rotational speed at which the vibration becomes large, the vibration of the individual unit is smaller than a predetermined value at the time of the previous dehydration process or before the dehydration process, and When the local maximum value can be calculated from the vibration detected by the individual unit vibration detecting means 50a, the rotational speed at which the local maximum value is obtained may be recorded in the control unit 4.

  After performing such a dehydration process for a predetermined time, the water supply valve 10a is opened and water is supplied. The water passes through the detergent container 12 and the water supply path 10b, and is poured into the outer tub 23 together with the detergent, and the rinsing process is performed. In this rinsing step, as in the washing step described above, the forward rotation, pause, inversion, and pause operations are repeated, and the laundry is lifted and lifted in the rotational direction by the lifter 21b provided on the inner peripheral wall of the drum 21. The rinsing operation is repeated for a predetermined time in which the stirring operation of dropping from the height position is repeated. Thereafter, the dehydration process and the rinsing process described above are repeated a predetermined number of times, and the process proceeds to the final dehydration process. The dehydration time in this final dehydration step is set longer than that in the above dehydration step.

  Furthermore, when the drying process is selected, the drying unit 40 which is one of the individual units blows the dried air into the outer tub 23, and the drum 21 is rotated forward, stopped, reversed, stopped. The operation is repeated to remove moisture from the laundry in the drum 21. For example, as shown by the arrows in FIG. 3, the air that has absorbed the moisture of the laundry in the outer tub 23 is sucked into the dehumidification duct 40a from the bellows hose 40f by the fan 40c, and after the moisture is removed there, the lint filter 40b The lint contained in the air is collected. Further, the air is warmed by the heater 40d, is blown into the outer tub 23 through the air passage 40e and the bellows hose 40g, and absorbs moisture in the outer tub 23 again. Instead of using the dehumidifying duct 40a, a method of exhausting wet air from the drain hose 13 and sucking dry air from the outside may be used.

  In the above drying process, in the present embodiment, since the drying unit 40, which is one of the individual units, includes the vibration detection means 50a, the vibration of the fan 40c is detected and whether it is operating properly. It can also be inspected. For example, when the detection vibration of the fan 40c in the drying process is large with respect to a predetermined value determined in advance, the detection result can be notified to the user by notifying the display panel 3a. This notification means may be a method in which information is recorded not only on the display panel 3a but also on the control unit 4 and the information is electrically output to the outside. Thus, in this embodiment, since the operation state of the drive unit such as the fan 40c can be detected by the individual unit vibration detection means 50a, it is possible to save the trouble of disassembling when examining the presence or absence of the abnormality. This saves you the trouble of installing a separate measuring device.

  The above-described effects have been described with respect to the drum-type washing and drying machine as an example. However, the drum-type washing machine without the drying unit 40, the vertical type laundry drying machine or the vertical type with the input port 2a facing substantially upward. The same applies to washing machines. Even when the outer tank vibration detection means 27 is not provided, the same effect can be obtained by providing the individual unit vibration detection means 50a.

  FIG. 6 is a rear view showing the internal structure of the housing 1 in the second embodiment, and shows a state in which the back plate 1f is removed. Similar to the first embodiment, individual units such as the control unit 4, the water supply unit 10, or the drying unit 40 that are supported by the housing 1 by means different from the outer tub 23 are disposed in the housing 1. Further, the water supply unit 10 is provided with individual unit vibration detection means 51 a for detecting the vibration of the water supply unit 10. Other configurations and the rotation control of the drum 21 are the same as those in the first embodiment, and the same reference numerals are given and the description thereof is omitted.

  According to the above configuration, as in the first embodiment, the vibration of the water supply unit 10 is detected by the individual unit vibration detection means 51a, thereby preventing the vibration of the water supply unit 10 from being excessive and generating abnormal noise. The rotational speed of the drum 21 can be increased. Further, the water supply unit 10 detects the shock and vibration by the individual unit vibration detection means 51a when an abnormality occurs in the water supply valve 10b due to, for example, a water hammer effect caused by tap water pressure. Abnormalities can also be detected or notified.

  FIG. 7 is a right side view showing the internal structure of the housing 1 in the third embodiment, in which the front cover 1a, the top cover 1b, the back reinforcing plate 1f, and the right plate 1d are omitted. In the housing 1, individual units supported by the housing 1 by means different from the outer tub 23 are arranged, such as the control unit 4, the water supply unit 10, the drying unit 40, or the pump unit 14. The pump unit 14 drains the water discharged from the outer tub 23 to the outside of the machine by power, and includes individual unit vibration detection means 52 a for detecting the vibration of the pump unit 14. Other configurations and the rotation control of the drum 21 are the same as those in the first embodiment, and the same reference numerals are given and the description thereof is omitted.

  According to the above configuration, as in the first embodiment, the vibration of the pump unit 14 is detected by the individual unit vibration detection means 52a, thereby preventing the pump unit 14 from excessively vibrating and generating abnormal noise. The rotational speed of the drum 21 can be increased. In addition, since washing water or rinsing water flows into the pump unit 14, for example, when a foreign object enters and vibration or abnormal noise occurs, the vibration due to the foreign object is detected by the individual unit vibration detection means 52 a provided in the pump unit 14. And detecting or notifying the abnormality as in the first embodiment. In addition, although the pump 14 unit of a present Example aims at drainage, also when aiming at circulating water in the outer tank 23, it has the same effect.

  FIG. 8 is a right side view showing the internal structure of the housing 1 in the fourth embodiment, in which the front cover 1a, the top cover 1b, the back reinforcing plate 1f, and the right plate 1d are omitted. In the housing 1, an individual unit supported by the housing 1 by means different from the outer tub 23, such as the control unit 4, the water supply unit 10, or the heat pump unit 41, is disposed. The heat pump unit 41 includes a pipe line 41e for circulating the refrigerant, a compressor 41a that compresses and vaporizes the refrigerant in the pipe line 41e to a high temperature and a high pressure, and a radiator 41b that superheats the air with the high temperature refrigerant. A throttling means 41c for reducing the pressure of the refrigerant after heat exchange to low temperature and low pressure, a heat absorber 41d for cooling and dehumidifying the air with the low temperature refrigerant, a heat pump unit 41 and the outer tub 23, And a fan 40g for sending the air in the outer tub 23 to the radiator 41b and the heat absorber 41d. The heat pump unit 41 includes individual unit vibration detection means 53 a for detecting vibration of the heat pump unit 41. Other configurations and the rotation control of the drum 21 are the same as those in the first embodiment, and the same reference numerals are given and the description thereof is omitted.

  According to the above configuration, by detecting the vibration of the heat pump unit 41 by the individual unit vibration detection means 53a, the rotation speed of the drum 21 is increased while preventing the vibration of the heat pump unit 41 from being excessive and generating abnormal noise. I can do it.

  Moreover, since the compressor 41a has a rotation drive part, it may generate vibration and cause abnormal noise. At this time, the vibration of the compressor 41a can be detected by the individual unit vibration detection means 53, and the abnormality can be detected or notified as in the first embodiment.
