Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an automatic washing machine that performs water injection rinsing in the rinsing process.

2. Description of the Related Art Conventionally, this type of automatic washing machine has a structure as shown in FIG. In Fig. 5, there are a plurality of small holes 3 on the outer periphery.
A washing tub 31 for rinsing and cleaning has a pulsator 32 at the bottom, a water receiver is housed inside the tub 33, and the water receiver has one overflow port 34 formed near the top of the tub 33. 35 is the external structure. In this type of device, when water injection/overflow rinsing is performed at a low water level, overflow rinsing is only performed after the water level reaches the overflow port 34.

Problems to be Solved by the Invention As described above, in the conventional washing machine, even when performing water filling and overflow rinsing at a low water level, hot water is not supplied until the water level reaches the overflow port 34 near the top of the washing tub 31. Since J-rinsing is not performed, it takes time for detergent foam, lint, etc. floating near the water surface to come out of the washing tub 31, and the effectiveness of the plow is greatly reduced due to water injection and overflow. Furthermore, when using the water supply in a place with low water pressure, even if you set the water injection/flooding function at the low water level, the water will overflow within a limited time.
Since the water level does not reach up to 34, water injection and hot water susuzu cannot be realized, and there is a problem in that the result is only the same as that of covering without overflowing.

The present invention aims to solve these problems and to provide an automatic washing machine that can always perform overflowing even at low water levels.

Means for solving and overcoming the problems In order to solve the above problems, the present invention provides water level detection means for detecting the water level in the washing tub in N stages (N is a natural number);
The user sets the water level in the washing area to number 11 [1 (1≦“]
≦N), N overflow ports integrally molded on the outer wall of the washing tub and capable of overflowing at N levels of water levels, and N overflow hoses connected to the N overflow ports. Said N
an N-stage overflow means configured to control N overflow valves installed at the tip of a main overflow hose, a washing recycle setting means that allows a user to arbitrarily set a washing cycle, and the water level detection means; Based on the signals from the water level setting means and the washing power cycle setting means, the water supply valve driving means, the pulsator driving means, and the N
The system is equipped with a control means for independently controlling the staged water flooding means to perform water injection and hot water filling at N stage water levels.

Function The above configuration enables water injection and overflow rinsing even at low water levels, and this water injection and overflow rinsing improves the rinsing effect and removes detergent foam and lint.
Furthermore, it is possible to shorten the time required for water supply and drainage when covering, and as a result, even in areas with low water pressure, the effect of water injection and water overflow can be improved even in areas with low water pressure. It is possible to improve efficiency.

EXAMPLE An example of the present invention will be described based on the drawings.

FIG. 1 is a block diagram of main parts showing the configuration of an embodiment of the present invention. In FIG. 1, the water level in the washing tub is detected by the water level detection means 1 in N stages 113 (N is a natural number). The water level is set to a predetermined water level by the user using the water level setting means 2, and the user sets whether to perform the accumulation during washing or the 1-receipt process using the washing power cycle setting means 3. The storage means 4 stores water level data from the water level detection means 1, the water level setting means 2, and the washing cycle setting means 3.

The control means 5 receives the output of the storage means 4 and controls the water supply valve driving means 6 to open and close the water supply valve to flow water into the laundry premises, and also controls the N stage hot water 1 stage 7. Control the temperature and pump hot water to the set water level one after another.Furthermore,
The pulsator driving means 8 is controlled to rotate and stop the pulsator.

FIG. 2 is a diagram showing a specific configuration. In FIG. 2, reference numeral 9 denotes a washing tub, and a pulsator 10 rotated by a first pulsator drive stage 8 is provided at the bottom 4-J.

The water level detection means 1 is composed of a whistle 12J communicating with the washing tub 9 and N stages of optical detectors 1b. Water supply valve 1
1 is opened and closed by a water supply valve driving means 6. Again outside 4!1
On the wall of 2, there are N pieces that can overflow at N stages of water level.
Staged overflow ports 13 are formed, and the lower part corresponding to each overflow port 13 is connected to N overflow hoses 15 via N independent overflow valves 14, and each overflow valve 14 is connected to N stage overflow means. Opening/closing is controlled by 7. As shown in FIG. 1, the microcomputer 16 consists of a storage means 4 and a control means 5, determines the water level according to a built-in program, and controls the water supply valve 11, N overflow valves 14, and pulsator 1.
Generates signals for driving each 0 independently.

Next, the operation of this embodiment will be explained. FIG. 3 shows the main part of a flowchart controlled by the microcomputer 16. In Figure 3, when the laundry enters the rinsing process,
In step 21, the micro combi coater 16 opens the water supply valve 11 via the water supply valve driving means 6 to allow tap water to flow therein. At that time, the pulsator 10 remains stopped, and 1 to
The N-stage overflow valve 14 remains closed. When detecting that the water level has reached the set water level (nth water level, 1≦n≦N) in step 22, the micro combi coater 16 moves to the stirrup 23 and the water supply valve 11 turns to u17; 11. Well, the pulse rotates 10 overnight via the pulsator drive f stage 8,
At the same time, only the nMth hot water valve 14 is heard. As a result, water overflows from the )th overflow port 13 while maintaining the water level at the nth state, and water injection and overflow can be realized. This state continues until the end of the Suzagi time. If the end of the two-to-one time is detected in step 24, the water supply valve 11 is closed in step 25, and the pulsator 10 is stopped.
By closing the first overflow valve 14 as well, all the overflow valves 14 are closed and the process proceeds to the next washing process.

This conclusion of Song, 't' in Figure 1? As shown in the characteristic diagram showing the condition of water leakage, by using the water injection/overflowing process instead of the general T culm B of the storage water, drainage water, and sweat water, the above general The time can be shortened by the amount of water injection time in process B.

Effects of the Invention As described above, according to the present invention, it is possible to continuously pour and overflow water to n-level water levels, and greatly improve efficiency by removing detergent foam phosphorus, etc. can be realized. Furthermore, Tame'? l-i Drainage - Water injection - General of Tamezusu - The time can be shortened by the amount of time required for water injection at the culm, and can be used in areas with low water pressure and areas where it takes a long time to pour water into the culm. The effect of shortening washing time is very noticeable. In this way, water injection and drainage of 71-7J' are achieved regardless of the height of the water level, improving suzugi efficiency.
In addition, it is possible to shorten the washing time especially in areas where the water pressure of tap water is low.
