1 is a longitudinal sectional view of a dish washing machine according to an embodiment of the present invention, FIG. 2 is a front view of the dish washing machine of FIG. 1, and FIG. 3 is an enlarged cross sectional view of the mist generating means of the dish washing machine of FIG. 1.

The structure of the present invention is particularly characterized by the mist generating means 14 and the temperature detecting means 8a as compared with the conventional art. The mist generating means 14 is to disperse the high concentration detergent liquid in which the detergent is dissolved in a small amount of water in the washing tank 2, and attach the detergent mist of the scattered fine particles to the tableware 9.

3 shows a mist generating means 14. The mist generating means 14 includes an ultrasonic oscillation device 15, a case 16 which protects the ultrasonic oscillation device 15 from contamination, and the like, a transfer fluid 17 enclosed in the case 16, and a case ( 16, the cover 18 is comprised. The cover 18 is provided with a hole 19 through which the generated mist passes. The cover 18 also serves as a detergent inflow, and has a detergent inlet 21 so that the detergent 20 does not directly contact the case 16. The temperature detection means 8a employs, for example, a thermistor provided on the lower surface of the washing tank 2 and detects the temperature of the washing water and the temperature of the washing machine main body.

The dishwasher according to the present embodiment has a pretreatment step of dispersing the detergent liquid to the tableware 9 by the mist generating means 14 and leaving it therein. In this pretreatment step, a mist generation predetermined level or less for obtaining a predetermined amount of mist generation is provided. After water supply, the mist generating means 14 is driven to scatter the detergent mist of the fine particles. The water supplied by the washing water is heated by the heater (heating means) 10 to generate convection in the washing tank 2 to effectively fill the detergent mist in the washing tank 2.

In the pretreatment step, when the washing water is heated by the heater 10, the detection temperature T0 of the temperature detection means 8a at the start of operation and the detection of the temperature detection means 8a after a predetermined time after the start of operation are detected. The temperature T1 controls the drive time of the mist generating means 14 and the drive time of the heater 10 in the pretreatment step.

In the above configuration, the operation and operation will be described. First, the standard amount of detergent 20 is put into the detergent inlet 21 of the mist generating means 14, and operation starts. Water is supplied from the water supply valve (water supply means) 3 to a mist generation predetermined water level 22 or less for obtaining a predetermined amount of mist generation. In this case, the water supply amount of a predetermined amount is set by water quantity detection means (not shown) which detects a quantity of water. However, it is also possible to supply water for a predetermined time by the water supply valve 3 having a constant flow rate. Since the mist generation amount is inversely proportional to the water level, the mist generation amount can be increased by increasing the mist generation amount to a level below that for the mist generation predetermined water level 22 for obtaining the predetermined mist generation amount.

Next, when the ultrasonic oscillation device 15 of the mist generating means 14 is driven as a pretreatment process, ultrasonic waves are transmitted through the transfer liquid 17 and the case 16, and mist containing the detergent component is generated from the water surface. Since the detergent is put into the cover 18 of the mist generating means 14, the washing water in the cover 18 is drastically increased in the detergent concentration. For this reason, mist with a high detergent concentration is generated, and a high concentration of detergent mist as fine particles is scattered in the washing tank 2. The high-density detergent mist of the fine particles adheres to the tableware 9, and chemically decomposes the contamination of the fine-particle detergent mist to the tableware 9 by the surface active force of the high-density detergent mist of the fine particles. For this reason, it becomes possible to make the contamination adhered to the tableware, especially the contamination, such as a lipstick and tea sediment, from the table surface.

In the pretreatment process, when the detection temperature T0 at the start of operation, that is, the room temperature is low, the drive time of the mist generating means 14 and the drive time of the heater 10 in the pretreatment process are lengthened, and a predetermined time elapses after the start of operation. When the detection temperature T1 of the subsequent temperature detection means 8a, that is, the water supply water temperature is low, the drive time of the mist generating means 14 and the drive time of the heater 10 in the pretreatment step are lengthened. In detail, it controls as shown in Table 1. FIG.

Table 1

Drive time of mist generating means

        T0 T1 Less than 5 ℃ More than 5 ℃ less than 25 ℃ It is less than 45 degrees Celsius more than 25 degrees Celsius 45 ℃ or more Less than 5 ℃ 8 minutes 7 minutes 6 minutes 6 minutes More than 5 ℃ less than 25 ℃ 7 minutes 6 minutes 5 minutes 5 minutes It is less than 45 degrees Celsius more than 25 degrees Celsius 6 minutes 5 minutes 4 minutes 4 minutes 45 ℃ or more 5 minutes 4 minutes 3 minutes 3 minutes

Drive time of heater

        T0 T1 Less than 5 ℃ More than 5 ℃ less than 25 ℃ It is less than 45 degrees Celsius more than 25 degrees Celsius 45 ℃ or more Less than 5 ℃ 7 minutes 6 minutes 5 minutes 5 minutes More than 5 ℃ less than 25 ℃ 6 minutes 5 minutes 4 minutes 4 minutes It is less than 45 degrees Celsius more than 25 degrees Celsius 5 minutes 4 minutes 3 minutes 3 minutes 45 ℃ or more 4 minutes 3 minutes 2 minutes 2 minutes

Since the surface active force of the detergent mist of the fine particles is proportional to the temperature, the mist generating means is detected by the detection temperature of the temperature detecting means, i.e., when the room temperature is low and when the detecting temperature T1, i.e., the water temperature is low. By lengthening the drive time, the cleaning performance can be further improved. In addition, since the detergent mist of the fine particles is heavier than the air, it stays in the lower portion of the washing tank, but when the detection temperature T0, that is, the room temperature is low, and when the detection temperature T1, that is, the water temperature is low, the driving time of the heater is increased, Convection upwards is generated in the cleaning tank to efficiently fill the detergent mist in the cleaning tank, thereby further improving the cleaning performance. As a result, the amount of mist generated and the filling of the mist into the washing tank can be assured regardless of the room temperature or the water temperature of the water supply, and stable washing performance can be obtained.

In addition, in this embodiment, although the drive time of the mist generating means 14 and the drive time of the heater 10 are lengthened in the pretreatment process, the maximum cleaning performance is improved, but either time is lengthened. In either case, the same cleaning performance improvement effect can be obtained.

Moreover, in this washing | cleaning process after scattering high concentration detergent mist of microparticles | fine-particles from the mist generating means 14 in this pretreatment process, water supply valve 3 further supplies water for a predetermined time, and the washing | cleaning pump 5 supplies air It is set to the mist generation | prescribed predetermined water level 22 which does not generate the abnormal noise etc. which generate | occur | produce when it turns into a state of revolution (called cavitation). In this embodiment, although water is supplied for a predetermined time, the water supply amount of a predetermined amount can also be set by water quantity detection means (not shown) which detects water quantity. Thereby, the capability of the washing | cleaning pump 5 can be exhibited stably, and stable washing | cleaning performance can always be obtained. When water supply is complete | finished, it energizes the heater 10 and heats wash water. Here, washing is performed by spraying the washing water from the washing nozzle 6 with the washing pump 5. At this time, the washing | cleaning is performed effectively with respect to the contamination of the excited tableware 9 by the action of the detergent mist of high concentration which is microparticles | fine-particles.

As described above, in the present embodiment, the mist generating means 14 has a pretreatment step of dispersing the detergent mist of fine particles to the tableware 9, and the mist generating means 14 is output by the output of the temperature detecting means 8a. By controlling at least one of the drive and the heater 10, the surface active force of the detergent mist of the fine particles can be controlled to the maximum, and the cleaning performance can be significantly improved.

In addition, the water level of the washing water supplied in the pretreatment step is set to the mist generation predetermined level 22 or less with respect to the mist generation predetermined water level 22 for obtaining a predetermined amount of mist generation. In order for the mist generation amount to be inversely proportional to the water level, with respect to the mist generation predetermined level 22 for obtaining the predetermined amount of mist generation, the level of the washing water supplied in the pretreatment step is set to be the mist generation predetermined level 22 or less, thereby reducing the mist generation amount. It can increase and the cleaning performance can be improved further.

In addition, in the present washing step, water is supplied up to a predetermined amount as much as the water level 23 in the pretreatment step, thereby preventing cavitation of the pump and the like, thereby obtaining a stable discharge capacity of the washing water, and the washing water is a detergent of fine particles. Washing can be performed effectively with respect to the contamination of the floated tableware 9 with the mist attached.

The dishwasher according to the present invention can significantly improve the cleaning power by having a pretreatment step of leaving the mist of particulates attached to the object to be cleaned and leaving it to stand. In addition, the cleaning performance can be further improved by controlling the drive of the mist generating means by the detection temperature of the temperature detecting means in this pretreatment step. In addition, since the amount of mist generated can be increased and the cleaning performance can be further improved by setting the amount of the washing water supplied in the pretreatment step to be less than or equal to the mist generation level, the dishes to be washed by spraying the washing water onto the objects to be cleaned, such as tableware. It is useful as a washing machine or the like.

In addition, the present invention has been described as washing dishes. However, since it is applicable also to washing of dishes, cooking utensils and kitchen utensils, the industrial applicability is high.
