Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a dehydrating and rinsing machine that rinses laundry by pouring water into the dehydrating cylinder and rotating the dehydrating cylinder.

[Technical background of the invention]

When rinsing with this type of dehydrator, in areas where the water source is of poor quality, if the water from the water source is poured directly into the laundry in the dehydrator, impurities such as iron oxide powder contained in the water will be washed away. It sticks to things and changes the laundry.J-1,\21T
Eye-heavy Neshobi suit 4X sheath pattern 71. %ru. For this reason, dehydrating and rinsing machines used in areas with poor water quality must be equipped with a filter that filters water from a water source and supplies it to the dehydrating cylinder. In this case, it was common to provide a filter separately from the main body of the dehydrating and rinsing machine.

[Problems with background technology]

However, if the filter is installed separately from the main body, the main body can be exactly the same as the one for areas with good water quality, so there will be no problems in manufacturing the dewatering tinner. However, when using the IB2 water rinsing machine, it requires space to install the filter in addition to the installation space for the main unit, so the installation space becomes large and the handling is troublesome. There are drawbacks.

[Purpose of the invention]

Therefore, an object of the present invention is to allow a filter manufactured separately from the main body to be installed in the main body, and also to allow the main body to be used in common with a main body without a filter, thereby improving manufacturability. To provide a dehydrating J-rinsing machine that can be used without increasing the size of the installation space.

[Summary of the invention]

In order to achieve the above object, the present invention includes a filter in the main body.
It is designed to be removable.

7 is a filter detachably housed in the storage recess 21;
The structure will be explained in detail below. That is, 28 is a main body case, which consists of a container-shaped case main part 29 with an open upper surface and a lid part 31 detachably attached to the upper surface opening via a sealing member 30. Reference numeral 32 denotes a filter member formed into a cylindrical shape, and the openings at both ends thereof are connected to a fitting cylindrical portion 29a formed on the inner bottom of the case main portion 29 and a fitting cylindrical portion 31a formed on the lower surface of the lid portion 31, respectively. The filtration member 32 divides the inside of the main body case 28 into a water inflow chamber 33 located outside the filtration member 32 and a water outflow chamber 34 located inside the filtration member 32. 35 is the water inflow chamber 33
It is a flat part formed on the upper part of the tank that extends rearward (to the right in Figures 3 and 4), and it has a water inlet 36 (see Figure 3) and a downward-facing overflow pipe with an overflow port 37a inside. Part 37
(See Fig. 4) are arranged side by side on the left and right with water-shielding walls (not shown) in between. By storing the main body case 28 in the storage recess 21, the water inlet 36 is fitted and connected to the joint cylinder part 23 from above for attachment/detachment θ, and the overflow cylinder part 37 can be attached to and detached from the socket 24 from above. is inserted and concatenated into.

Reference numeral 38 denotes a water outlet tube portion provided downward at the bottom of the water outlet 34, and its interior serves as a water outlet 38a.

This water outlet cylinder portion 38 is detachably inserted into and connected to the socket 22 from above. Reference numeral 39 denotes a transparent cap provided on a portion of the lid portion 31 of the main body case 28 located above the water overflow port 37a, and water inflows through the transparent cap 39.
33 including the vicinity of the overflow hole 37a can be seen through. The filter 27 configured as described above is connected to the operation box 2.
It is removably stored in the storage recess 21 of a, but when manufacturing a structure that does not include the filter 27 for areas with good water quality, the joint cylindrical part is 2
3 and the socket 22 through a connecting pipe 40,
The open surface part of the four storage parts 21 is covered with a nail panel 41.

Next, the operation of the above configuration will be explained. In a device equipped with a filter 27, when performing a dehydration tin operation after a washing operation, the water faucet 20 is opened in advance, and at the same time, the water sprinkling tube 6 in the dehydration 11i 5 is opened. The laundry that has been washed with detergent is stored in the same area, the inner lid 7 and the outer lid 15 are covered, and the dehydration cylinder 5 is rotated at high speed by the dehydration motor (not shown) by operating the dehydration timer 17. Centrifuge the detergent solution. When a predetermined period of time has elapsed after the start of dehydration, the dehydration cylinder 5 is driven intermittently and the water supply valve 18 is opened. Thereafter, the tap water flowing into the water supply valve 18 is adjusted to a substantially constant flow rate by the flow rate adjustment device, and is supplied into the water inlet chamber 33 from the water inlet 36 of the filter 27 through the connecting pipe 25. The water supplied into the water inflow chamber 33 is stored in the water inflow chamber 33 and permeates through the filtering member 32 due to its water head, where impurities such as iron oxide powder are captured and removed before entering the water outflow chamber 3P4. The amount of water supplied from the water outlet 38a is 9.
flow down inside. By the way, immediately after the start of water supply, the water inflow chamber 33
Since the water level inside the filter member 32 is low and the water head is small, the filter member 32
The flow rate of water passing through is smaller than the amount of water supplied into the water inflow chamber 33, and the water level in the water inflow chamber 33 gradually rises. Since it is discharged outside the main body case 28, the internal pressure inside the main body case 2B does not increase. After a while, the water supply flow m into the water inflow chamber 33 and the flow rate of water passing through the filter member 32 become equal, and from this point on, the water level in the water inflow chamber 33 is shown as a solid line in FIGS. 3 and 4. Normally maintained at water level. On the other hand, the water that has been filtered by the filter member 32 and flows down from the water outlet 38a into the water supply volume 9 flows down the water supply volume 9, flows from the lower end of the water supply volume 9 into the water injector 8 through the water inlet 10, and flows into the water inlet 11. The water flows down into the water spray tube 6 from there. Then, the water supplied into the water spray barrel 6 is transferred to the water spray barrel 6 by centrifugal force.
It is ejected from the surrounding wall and makes the surrounding laundry hydrated.

The water contained in the laundry is thus separated by the centrifugal dehydration action caused by the rotation of the dewatering capacity 5, and the laundry is rinsed by such water absorption and centrifugal dehydration action. In this case, even if the tap water discharged from the faucet 20 contains impurities such as iron oxide powder, the impurities are captured and removed by the filtering action of the filter member 32 as described above. Discoloration of laundry due to dehydration and rinsing is also prevented in local areas.

On the other hand, in the dewatering and rinsing machine shown in FIG. 5 in which the filter 27 is omitted, the tap water supplied from the water supply valve 18 through the connecting pipe 25 flows into the water supply volume 9 through the connecting pipe 40.
Thereafter, water is poured into the dewatering capacity 5 in the same manner as described above.

As described above, according to the above embodiment, the filter 27 is removably provided in the four storage parts 21 provided in the operation box 2a of the main body 1, so when the filter 27 is stacked, the filtration
The container 27 is stored in the four storage parts 21 from above the storage recess 21, and the water inlet 36. Overflowing water sign n7...1C mountain clerk snake Ot
It is only necessary to connect the earthen heel support to the opening 24 and the socket 22, which makes it easy to install the filter 27.If the filter 27 is not needed, the filter 27 can be installed easily. 2
7, as shown in FIG.
2 through a connecting pipe 40, and the storage recess 21
By just covering the open surface of the filter 27 with the decorative panel 41, the filter 27 can be omitted.
Since there is no need to change the configuration of the main body 1 at all regardless of the presence or absence of the main body 7, it is excellent in manufacturability. Furthermore, since the filter 27 is provided in the operation box 2a of the main body 1, there is no need to provide a separate installation space exclusively for the filter 27 during installation, and therefore the installation space does not become large.

By the way, when the filter member 32 becomes clogged due to long-term use, the water flow resistance of the filter member 32 increases, but the water supply valve 1
Since a constant flow of water is always supplied into the water inflow chamber 33 by the action of the flow rate adjustment device 8, the water level in the water inflow chamber 33 rises further beyond the normal water level. However, when the water level attempts to rise beyond the overflow port 37a located at a predetermined height of the water inflow chamber 33, the water overflows from the overflow port 37a and flows into the washing tub 3 through the overflow pipe 26. Therefore, the user can visually check the water overflowing from the overflow port 37a through the overflow @26 into the washing machine 4!3, or visually check the water overflowing from the overflow port 37a through the transparent cap 39, so that the filtration member 32 is It is possible to recognize that the filter is clogged, and by using this as a guide, the filter member 32 can be replaced at an appropriate time. Furthermore, even if the water level in the water inflow chamber 33 rises abnormally due to clogging of the filter member 320, the water supply pressure will not be directly applied to the main body case 28 because it will stop slightly beyond the water overflow port 37a. Therefore, even if the main body case 28 does not have a pressure-resistant structure as in this embodiment, it can be used satisfactorily. Furthermore, in the treatment of water discharged from the overflow port 37a, if the filter 27 is attached to the main body 1 as in the present invention, communication with the drainage path of the main body 1 can be easily achieved, so it is not necessary to install the filter separately. Unlike conventional products that require installation, there is no need to worry about getting the floor wet, greatly improving usability.

Note that the location where the filter 27 is provided is not limited to the operation box 2a of the main body 1, but may be placed in the outer box 2 of the main body 1, for example, and the present invention can be modified in various ways without departing from the gist.

〔Effect of the invention〕

As is clear from the above description, the present invention has a structure in which a filter that filters water from a water source and supplies it to the dehydration cylinder is removably installed in the main body. Not only can it be installed in the main body, but it can also be used in common with the main body without a filter, which improves productivity and has the excellent effect of not requiring a large installation space. We can provide a dehydrating and rinsing machine for you.
