[0008] (The knowledge and other information that formed the basis of this disclosure) In order to remove wrinkles from the fabric of a processing object such as clothing, spraying high-temperature steam onto the wrinkled portion as with a steam iron is an effective means. In a clothing processing device according to the prior art, the processing object is suspended in a main body, exposed to steam, and dried to perform clothing processing such as removing wrinkles and deodorizing. In this case, a water supply tank is provided in a steam supply device that generates steam. This water supply tank is configured to be detachable from the main body, and a water level sensor that detects the water level of the water supply tank is configured to include, for example, a float case fixed to the water supply tank, a float arranged inside the float case and configured to move up and down inside the float case based on the water level of the water supply tank, and a sensor arranged on the main body side and configured to magnetically detect the float.

[0009] However, since the water tank is removed from the laundry treatment device body and transported in order to supply water, there is a risk that the water tank may be subjected to impact, such as being dropped by a user during transportation. If an impact is applied to the water tank in this way, the float, float case, and other parts disposed in the water tank may be damaged.

[0010] Therefore, the inventors focused on configuring the functional parts of the water level detection unit on the main body side to prevent them from being transported unnecessarily, and have provided the subject matter of the present disclosure.

[0011] In order to solve this problem, the present disclosure provides a clothing treatment device that configures a water supply passage on the main body side that connects the connection part where the water supply tank is attached and detached to the steam generation part, and provides a water level detection part in this water supply passage that detects the water level in the water supply tank, thereby eliminating the need for a water level detection part in the water supply tank, making it easier to handle the water supply tank and improving reliability.

[0012] Hereinafter, the embodiments will be described in detail with reference to the drawings. However, more detailed description than necessary may be omitted. For example, detailed description of already well-known matters or duplicate description of substantially the same configuration may be omitted.

[0013] It should be noted that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0014] (Embodiment 1) The first embodiment will be described below with reference to FIGS. 1 to 5.

[0015] [1-1. Basic configuration of the clothing treatment device] Fig. 1 is a schematic perspective view of a clothing processing device 100 according to the present embodiment. Fig. 2 is a schematic perspective view in which a liquid tank device 80 provided at the lower front part in Fig. 1 has been removed to expose a machine chamber 7.

[0016] As shown in FIG. 1, the housing 1 of the clothing processing device 100 includes an outer shell 2 having an opening on the front, and a door 3 for opening and closing this opening. A storage section 5 for storing items 4 to be processed, such as clothing, is provided so as to be contained within the upper space within the housing 1. In other words, the inner surface of the door 3 forms the storage section 5. A seal member 3a is attached to the outer periphery of the inner surface of the door 3 to match the opening of the storage section 5. The seal member 3a is made of a flexible material such as rubber. As a result, the storage section 5 becomes a closed space when the door 3 is closed, and airtightness is maintained.

[0017] The liquid tank device 80 includes a water supply tank 15, a drainage tank 18, and a tank housing portion 81 (FIG. 3). 2, a machine room 7 in which the air treatment device 6 and the like are housed is provided at the rear of the lower space in the housing 1. The objects 4 to be treated include clothing and small articles worn by people in general, as well as textile products in general, such as small articles like handkerchiefs, towels, and cloth bags.

[0018] A suspension unit 8 for suspending hangers 4a on which objects 4 to be treated are hung is provided at the upper part of the storage unit 5. The suspension unit 8 may be provided with a swinging mechanism for swinging the suspended objects 4 to be treated. In addition, shelves 8a or hooks for holding small items may be provided, and these are collectively referred to as the holding unit, including the suspension unit 8. An air treatment device 6 for circulating the air in the storage unit 5 by heating and dehumidifying it, and a steam supply device 13 for supplying steam into the storage unit 5 are provided in the machine room 7.

[0019] Fig. 3 is a side cross-sectional view of the clothing processing device 100 in this embodiment. As shown in Fig. 3, the storage unit 5 is formed of a case 5a separate from the outer shell 2, and is configured to have a space between the outer shell 2. A ventilation hole 31 and an opening / closing device 32 for opening and closing the ventilation hole 31 are provided on the top surface of the case 5a. The ventilation hole 31 is opened when the clothing processing device 100 is stopped, and serves as an entrance and exit for the air in the storage unit 5 to be naturally ventilated through the space between the outer shell 2.

[0020] As shown in Fig. 3, the machine room 7 is provided with an air treatment device 6 and a steam supply device 13. Fig. 4 is a schematic diagram of the configuration of the air treatment device 6 and the steam supply device 13 shown in Fig. 3.

[0021] The air treatment device 6 includes a dehumidifying section 10, an air heating section 9, a blower section 11, and an air passage 12 connecting these sections. The air passage 12 has an inlet 12a provided to open at the front of the lower surface of the storage section 5, and an outlet 12b provided to open at the rear of the lower surface of the storage section 5. The air passage 12 has a fan 11a and a motor 11b, and sucks in air from the inlet 12a in the storage section 5, blows it out from the outlet 12b to circulate it, and stirs the air in the storage section 5. The dehumidifying section 10 dehumidifies the circulating air in the drying step of the treatment operation to promote drying of the treatment object 4. Similarly, the air heating section 9 increases the temperature of the air in the storage section 5 to promote evaporation of moisture contained in the treatment object 4.

[0022] A drain tank 18 for storing condensed water dehumidified and collected by the dehumidifier 10 is provided from the dehumidifier 10 via a water collector 19 and a drain pump 20. The bottom surface of the storage unit 5 is formed at an angle so that condensed water that condenses and drips from the inner wall of the storage unit 5 can be collected, and a recovery pipe (not shown) is provided to guide the condensed water to the water collector 19. As a result, even if the humidity inside the storage unit 5 becomes high and condensed water is generated on the inner wall, the water is collected without leaking outside the main body. The drain tank 18, which functions as a water storage unit, is provided detachably so that the user can discard the accumulated water.

[0023] The air treatment device 6 may be configured, for example, as a known heat pump unit. The heat pump unit is configured by connecting a compressor, a condenser, an expander, and an evaporator with refrigerant piping, and heat exchange is performed by circulating refrigerant through the refrigerant piping. In the heat pump unit, the condenser corresponds to the air heating section 9, and the evaporator corresponds to the dehumidification section 10. If the air heating section 9 and the dehumidification section 10 are configured as a heat pump unit, the drying operation can be performed efficiently and with low power consumption, without forcibly discharging moisture to the outside of the housing 1 as a simple ventilation system, or using a large amount of dehumidification cooling water as in a water-cooling device.

[0024] The steam supply device 13 includes a water supply section 14 for storing the water to be supplied, a steam generating section 16, and a steam discharge section 17. The water supply section 14 includes a removable water supply tank 15, a connection section 14a to which the water supply tank 15 is connected to the main body side, a water level detection section 50 for detecting the water level in the water supply tank 15, a water supply pump 14b, and a water supply pipe 14c for connecting these sections. The water level detection section 50 is provided between the connection section 14a and the water supply pump 14b. In other words, the water level detection section 50 is a removable The water supply tank 15 is not provided in the water supply tank 15, but is fixed to the main body.

[0025] The steam generating section 16 includes a container 16a for storing water and steam and a water heating section 16b for heating and evaporating water, and a water supply pipe 14c from a water supply pump 14b is connected to the container 16a. The steam discharge section 17 includes a steam pipe 17a and a discharge port 17b connected to the steam generating section 16. The discharge port 17b opens into the storage section 5 at the tip of the steam pipe 17a. The discharge port 17b may be formed so that high-temperature steam does not directly hit the workpiece 4. This can suppress deterioration of the material due to the heat of the higher-temperature steam. In addition, a drainage path may be provided to guide condensed water generated by condensation in the vicinity of the discharge port 17b to the water collecting section 19. Furthermore, a control valve or the like may be provided to detect the pressure of the steam in the container 16a and control the discharge.

[0026] A control unit 40 that executes the processing operation of the clothing processing device 100 is provided at any location, such as the space above the rear of the storage unit 5. An operation unit 41 for setting the operation of the clothing processing device 100 is disposed on the front side of the door 3. Also, as shown in Fig. 1, an open / close detection unit 42 that detects the open / closed state of the door 3 may be provided at a predetermined location, such as the front side of the machine chamber 7. Furthermore, a temperature detection unit that detects the temperature inside the storage unit 5 may be provided at a predetermined location, such as the inner wall of the storage unit 5.

[0027] FIG. 5 is a schematic diagram of the operation unit 41 of the clothing processing device 100. The control unit 40 includes control of operation courses such as drying operation, wrinkle removal operation, and sterilization and deodorization operation, and also includes processing conditions such as "standard", "quick", and "thorough" according to each operation course. The control unit 40 is configured to control the operation according to these settings made by the user. The operation unit 41 is provided with an operation course setting button, a start / pause button, and other buttons, as well as a setting display for these, a time display, and a warning display. Note that, as a processing condition, a material setting for the object 4 to be processed, etc. may be provided. The power switch may be provided as an independent button on the operation unit 41. Furthermore, the power switch may be configured to be turned on by detecting static electricity when the user touches any part of the operation unit 41, or may be configured to be turned on by detection by the opening / closing detection unit 42 of the door 3, etc. Furthermore, the power switch may be configured to be automatically turned off if there is no operation by the user for a predetermined time T, including the operation unit.

[0028] The control unit 40 includes, for example, a steam supplying step in which, during the wrinkle-smoothing operation, the control unit 40 controls the steam supplying device 13 to generate steam in the steam generating unit 16. At this time, the control unit 40 operates the water supply pump 14b to supply water to the container 16a of the steam generating unit 16, and also energizes the water heating unit 16b to heat the supplied water to generate steam and release it into the storage unit 5.

[0029] In this manner, the control unit 40 controls the temperature inside the storage unit 5 to be a predetermined temperature. As a result, the temperature inside the storage unit 5 rises and the storage unit 5 becomes filled with steam, so that the object 4 contains a lot of moisture and wrinkles are easily removed.

[0030] Furthermore, in the wrinkle-smoothing operation, the control unit 40 may operate the air treatment device 6 after the steam supplying step to perform a drying step in which the air in the storage unit 5 is dehumidified, heated, and circulated. This promotes drying of the workpiece 4.

[0031] [1-2. Basic operation of the clothing treatment device] The operation of the crease-removing operation of the clothes processing apparatus configured as above will be described as an example. Fig. 6 is a flow chart of the crease-removing operation of the clothes processing apparatus in this embodiment, and the operation will be described in order of steps.

[0032] Step 1: The user opens the door 3 of the clothing processing device 100, and sets the object 4 to be processed, such as clothing to be smoothed, on the hanging section 8 above the storage section 5. The user closes the door 3 after setting the object.

[0033] Step 2: The user operates the operation unit 41 on the front side of the door 3. First, the user sets the operation course to be processed (in this embodiment, "smoothing out creases") using the operation course setting button. Next, the user selects the condition setting according to the operation course. Then, the user presses the start / pause button to start the crease-smoothing operation.

[0034] Step 3: According to the user's settings, the temperature and processing time of the storage unit 5 are set by the control unit 40, and the processing operation is started. In addition, the rocking operation of the suspension unit 8 may be set. In the wrinkle-smoothing operation, rocking the workpiece 4 can promote wrinkle-smoothing.

[0035] Step 4: The wrinkle removal operation is carried out for a predetermined processing time according to the settings.

[0036] Step 5: After the processing time has elapsed, the drying step is executed as appropriate. When the drying step is completed, the control unit issues a predetermined notification and ends the wrinkle smoothing operation.

[0037] As described above, the wrinkle-removing operation of the object 4 includes a steam supplying step in which the object 4 is exposed to steam in the storage section 5, and a drying step in which the object 4 is then dried by blowing air. As a result, the wrinkles on the fabric of the object 4 to be wrinkle-removing processed by the clothing processing device 100 are smoothed out and alleviated. In addition, the steam also exerts a deodorizing effect. Furthermore, the drying reduces the user's effort in ironing. Furthermore, if the material is set, the operating conditions are set differently depending on the material of the fabric in the steam supplying step, so that wrinkles can be removed more efficiently even for the object 4 made of a material that is difficult to remove wrinkles.

[0038] [1-3. Configuration and function of the water level detector in the water supply tank] As shown in Fig. 1, the liquid tank device 80 of the clothing processing device 100 is provided at the front of the lower space in the housing 1 of the clothing processing device 100. In addition to the water supply tank 15 and the drain tank 18, the liquid tank device 80 includes a tank housing section 81 (see Fig. 3) on the main body side, with the water supply tank 15 attached to the left area of ​​the tank housing section 81 and the drain tank 18 attached to the right area.

[0039] Fig. 7 is a schematic diagram showing the details of the steam supply device 13 in the air treatment device 6 and the steam supply device 13 shown in Fig. 4. The water supply tank 15 is configured to be detachable from the tank accommodation part 81, and is connected in a watertight manner at the connection part 14a. The connection part 14a includes a tank connection part 82 provided on the lower surface of the tank accommodation part 81 and a water supply connection part 84 provided on the outside of the bottom surface of the water supply tank 15, and these are connected via a seal member 82b such as an O-ring.

[0040] The tank connection part 82 has a water passage opening / closing valve 82a that opens and closes the opening of the water supply pipe 14c. The water passage opening / closing valve 82a is biased upward. This closes the opening of the water supply pipe 14c when the water supply tank 15 is detached, thereby preventing the water in the water supply pipe 14c from flowing back and leaking.

[0041] The water supply connection part 84 has a water supply opening / closing valve 84a that opens and closes the opening of the water supply tank 15. The water supply opening / closing valve 84a is biased downward. This closes the opening of the water supply tank 15 when the water supply tank 15 is detached, thereby preventing water from leaking from the water supply tank 15.

[0042] When the water supply tank 15 is installed and the water supply connection part 84 is connected to the tank connection part 82, the water passage opening / closing valve 82a and the water supply opening / closing valve 84a press each other up and down to open the openings that were closed. This connects the water supply tank 15 to the water supply pipe 14c. Pass.

[0043] A water level detector 50 for detecting the water level of the water supply tank 15 is disposed in the water supply pipe 14c. The water level detector 50 includes a float case 51, a float 52, and a magnetic sensor 53. The float case 51 is elongated in the vertical direction to match the height of the water supply tank 15, and is fixed in the machine chamber 7 of the clothing processing device 100. The float case 51 has a lower part connected to the middle of the water supply pipe 14c that communicates between the connection part 14a and the water supply pump 14b, and the inside of the float case 51 communicates with the water supply pipe 14c. As a result, when the water from the water supply tank 15 flows into the float case 51, the water level becomes the same height as the water level in the water supply tank 15.

[0044] Float 52 has a magnet built in and is formed with a specific gravity lighter than water, is arranged so as to be movable up and down inside float case 51, and moves up and down while floating on the water surface which changes according to the water level in water supply tank 15. Magnetic sensor 53 is disposed on the outside of float case 51, and is fixed in a position where it can magnetically detect float 52 when the water level in water supply tank 15 falls below a predetermined level.

[0045] In other words, the water level detection unit 50 is provided on the main body side of the clothing processing device 100, and is not provided on the detachable water supply tank 15. Therefore, the water supply tank 15 does not have the water level detection unit 50, and even if the water supply tank 15 is detached, the water level detection unit 50 is not carried along with the water supply tank 15.

[0046] Next, the water supply operation when a user uses the clothing treatment device 100 and the control of the clothing treatment device 100 will be described.

[0047] When using the clothing processing device 100, the user detaches the water supply tank 15 from the tank housing part 81 and moves it to a nearby water source. Then, the user fills the water supply tank 15 with tap water, carries the water supply tank 15 that is almost full to the clothing processing device 100, and attaches it to the tank housing part 81.

[0048] When the user detaches the water supply tank 15, the water passage opening / closing valve 82a and the water supply opening / closing valve 84a press against each other at the connection part 14a to close their respective openings. This prevents water leakage from the water supply tank 15 and water leakage due to backflow from the water supply pipe 14c.

[0049] When the user attaches the full water supply tank 15, the water passage opening / closing valve 82a and the water supply opening / closing valve 84a press each other up and down in the connection part 14a, thereby opening the previously closed openings. This allows the water supply tank 15 to communicate with the water supply pipe 14c.

[0050] The water in the water supply tank 15 flows into the water supply pipe 14c and also into the float case 51 of the water level detection unit 50, pushing up the float 52 to match the water level in the water supply tank 15. At this time, the control unit 40 detects by the magnetic sensor 53 that the water level in the water supply tank 15 is not below a predetermined value.

[0051] When the processing operation of the clothing processing device 100 is performed and steam is supplied, the amount of water in the water supply tank 15 decreases. In response to this, the float 52 of the water level detection unit 50 also descends. When the water level in the water supply tank 15 falls below a predetermined value, the magnetic sensor 53 detects the descended float 52. At this time, the control unit 40 detects by the magnetic sensor 53 that the water level in the water supply tank 15 is below the predetermined value, and executes a predetermined control, such as stopping the processing operation or notifying that water supply is necessary.

[0052] The user may then re-supply water depending on the status of the laundry treatment device 100. When a user carries the water supply tank 15 during water supply work, the user may unintentionally drop the water supply tank 15 or cause it to collide with something, causing an impact to be applied to the water supply tank 15.

[0053] According to this embodiment, the water level detection unit 50 is provided on the main body side of the clothing processing device 100, and is not provided on the detachable water supply tank 15. Therefore, the water supply tank 15 does not have the water level detection unit 50, and there is no risk of the water level detection unit 50 being damaged even if the water supply tank 15 is subjected to an impact during transportation. This makes it easier to handle the water supply tank 15 and improves its reliability.

[0054] [1-4. Effects, etc.] As described above, in this embodiment, the clothing processing device 100 includes a housing 1 having an outer shell 2 having an opening on the front side and a door 3 for opening and closing the opening, a holding section (suspending section 8) for holding the object 4 in the holding section 5, an air processing device 6 for processing and circulating the air in the holding section 5, and a steam supply device 13 for supplying steam into the holding section 5. The air processing device 6 includes a dehumidifying section 10, an air heating section 9, an air blowing section 11, and an air blowing passage 12 connecting these sections, the steam supply device 13 includes a steam generating section 16 for generating steam, and a water supply section 14 for supplying water to the steam generating section 16, and the water supply section 14 includes a detachable water supply tank 15, a water supply pipe 14c for connecting a connection section 14a where the water supply tank 15 is detachable to the steam generating section 16, and a water level detection section 50 provided in the water supply pipe 14c for detecting the water level of the water supply tank 15.

[0055] With this configuration, the water level detection unit 50 is provided on the main body side of the clothing processing device 100, and is not provided on the detachable water supply tank 15. Therefore, the water supply tank 15 does not have the water level detection unit 50, and there is no risk of the water level detection unit 50 being damaged by shock such as dropping the water supply tank 15 during transportation. This improves the reliability of the water supply tank 15 and makes it easier to handle.

[0056] In addition, in this embodiment, the connection portion 14a of the clothing processing device 100 includes a tank connection portion 82 provided on the water supply pipe 14c and a water supply connection portion 84 provided on the water supply tank 15, and the tank connection portion 82 has a water passage opening / closing valve 82a that closes the opening of the tank connection portion 82 when the water supply tank 15 is detached.

[0057] With this configuration, when the water supply tank 15 is detached, the opening of the tank connection part 82 is closed by the water passage opening / closing valve 82a, so that the water in the water supply pipe 14c can be prevented from flowing back and leaking.

[0058] (Other embodiments) As described above, the first embodiment has been described as an example of the technology disclosed in the present application. However, the technology in the present disclosure is not limited to this, and can be applied to embodiments in which modifications, substitutions, additions, omissions, etc. are made. In addition, it is also possible to combine the components described in the first embodiment to create new embodiments.

[0059] Therefore, other embodiments will be exemplified below.

[0060] In the first embodiment, a clothing treatment device 100 having a storage section 5 for the object to be treated 4 in the housing 1 has been described. However, the present invention is not limited to this, and any configuration capable of supplying steam to the held object to be treated 4 may be used. In other words, the storage section 5 is not limited to a closet, and may be a bag or cover made of a flexible and foldable resin or the like. Furthermore, as long as steam can be sprayed accurately onto the object to be treated 4, the storage section 5 may not be necessary, and a configuration in which the user moves the steam ejection section to supply steam to the object to be treated 4 may also be used.

[0061] That is, the apparatus includes a steam supply device 13 for supplying steam to the object 4, the steam supply device 13 including a steam generating section 16 for generating steam and a water supply section 14 for supplying water to the steam generating section 16, and the water supply section 14 includes a removable water supply tank 15, a water supply pipe 14c for connecting the connection section 14a where the water supply tank 15 is detached to the steam generating section 16, and a water level detection section 50 provided on the water supply pipe 14c for detecting the water level of the water supply tank 15. With this configuration, the clothing processing apparatus 100 does not have the water level detection section 50 in the water supply tank 15, and there is no risk of the water level detection section 50 being damaged by impact such as dropping the water supply tank 15 during transportation. This improves the reliability of the water supply tank 15 and makes it easier to handle. Then, the user can carry the clothing processing apparatus 100 and process the object 4 at any place.

[0062] In addition, in the first embodiment, the configuration of the float 52 and the magnetic sensor 53 has been described as the water level detection unit 50. However, this is not limited to this, and instead of the magnetic sensor 53, a mechanical sensor such as an electric resistance sensor, an electrostatic sensor, or a limit switch may be used. Also, instead of the float type, a weight sensor or other known technology other than the water level may be used. In any case, it is sufficient that the water level detection unit 50 is provided on the main body side, not on the water supply tank 15.

[0063] In the first embodiment, tap water is supplied from the water supply tank 15 as the steam generating device, but the present invention is not limited to this. For example, a tank for an agent solution may be provided to attach an agent to the object to be treated 4 such as clothes. The agent may be a known agent such as a deodorant for clothes, an aromatic, a weak acidifying agent, an antifouling agent, or a moisturizing agent designed for application to human skin.
