Embodiment

An example of embodiment of this invention is demonstrated using FIGS. The mist generating means 15 disperses a high concentration detergent liquid in which a detergent is dissolved in a small amount of water in the washing tank 2, and attaches the detergent mist of scattered fine particles to the object to be cleaned 9. 3 illustrates the occurrence of detergent mist. As shown in FIG. 3, the mist generating means 15 includes an ultrasonic oscillation device 16, a case 17 that protects the ultrasonic oscillation device 16 from dirt, and the delivery enclosed in the case 17. It consists of the fluid 18, the cover 19, etc. which cover the case 17. As shown in FIG. The cover 19 is provided with a hole 20 through which the generated mist passes. The cover 19 also serves as a detergent inlet, and has a detergent inlet 22 so that the detergent 21 does not directly contact the case 17. The temperature detection means 23 is 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 gas.

A blowing device 25 having a blower port 24 is provided in the vicinity of the mist generating means 15 so that detergent mist generated from the mist generating means 15 can be diffused into the cleaning tank 2 effectively. In this embodiment, this blower 25 also serves as a dry blower which blows dry air at the time of a drying process.

The dishwasher in the present embodiment has a pretreatment stroke in which the mist generating means 15 scatters the detergent liquid onto the object to be cleaned 9 and leaves it. In this pretreatment process, after water supply is carried out below the mist generation | prescribed predetermined water level in order to acquire predetermined | prescribed mist generation amount, the mist generating means 15 is driven to scatter the detergent mist of microparticles | 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 into the washing tank 2.

In the pretreatment stroke, the blower 25 is driven and blown from the blower port 24 provided near the mist generator 15 to promote the diffusion of the detergent mist into the washing tank 2.

In the above configuration, the operation and action will be described. First, the standard amount of detergent 21 is put into the detergent injecting part 22 of the mist generating means 15, and operation starts. Water is supplied from the water supply valve (water supply means) 3 to a mist generation predetermined water level 26 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. In addition, the water supply amount of the predetermined time by the water supply valve 3 of a fixed flow volume can also be used. Since the mist generation amount is inversely proportional to the water level, the mist generation amount can be increased and the effect can be expected further by setting the water level below that for the mist generation predetermined water level 26 for obtaining the predetermined mist generation amount.

Next, when the ultrasonic oscillation device 16 of the mist generating means 15 is driven as a pretreatment stroke, ultrasonic waves are transmitted through the transfer fluid 18 and the case 17 to generate mist containing the detergent component from the water surface. Since the detergent is put into the detergent inlet 22 provided in the cover 19 of the mist generating means 15, the detergent concentration in the cover 19 is very high. For this reason, mist with a high detergent concentration is generated, and fine and high concentration of detergent mist is scattered in the washing tank 2. The fine and high concentration detergent mist adheres to the object to be cleaned 9, and the fine particles of the detergent mist are attached to the object to be cleaned 9 chemically by the surface active force of the fine and high concentration detergent mist. Disassemble. For this reason, it becomes possible to make the dirt adhering to a tableware, especially dirt, such as a lipstick and tea water, float from a table surface.

Further, the blower 25 is driven in the pretreatment stroke and blown from the blower port 24 provided near the mist generator 15 to promote diffusion of the detergent mist into the washing tank 2. In addition, when the detection temperature T0 at the start of operation, that is, the room temperature is low, the blowing amount of the blower 25 in the pretreatment stroke is increased. Specifically, for example, the rotation speed of the blower 25 is increased or the drive time is increased.

And when the detection temperature T1 of the temperature detection means 23 after a predetermined time elapses after starting operation, ie, the water supply water temperature, is low, the air blowing amount of the blower 25 is increased. Specifically, Table 1 shows an example of changing the blowing amount depending on the driving time of the blower 25.

Table 1

Driving time of blower

Thereby, the time required for effectively filling detergent mist in the washing tank 2 is shortened until the convection effect in the washing tank 2 by the heating of the heater 10 occurs. That is, since the filling of the detergent mist into the washing tank can be surely performed in a short time regardless of the room temperature or the water temperature of the water supplied, stable washing performance can be obtained.

In addition, when the detection temperature T0 of the temperature detection means 23 at the start of operation is higher than a predetermined temperature (for example, when the second operation is performed immediately after the first operation, the temperature of the washing tank 2 is high). Case] If the mist generating means 15 is driven after driving the blower 25 for a predetermined time in the pretreatment stroke, the cleaning tank 2 can be cooled before the mist generating means 15 is driven. Therefore, even in such a case, when the mist generating means 15 is driven, the upward flow in the washing tank 2 is promoted, and the filling of the mist into the washing tank can be assured, and the high washing which is conventionally unstable. You can get performance.

Next, in this washing step after the fine mist and high concentration detergent mist is scattered from the mist generating means 15 in the pretreatment stroke, the water supply valve 3 further supplies a predetermined time water supply, and the washing pump 5 supplies air. It is set as the water level above the mist generation | prescribed predetermined water level 26 so that it may not blow in. 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 ability of the washing | cleaning pump 5 can be exhibited stably and the stable washing | cleaning performance can always be obtained. When water supply is complete | finished, it energizes the heater 10 and heats wash water. Here, the washing pump 5 sprays the washing water from the washing nozzle 6 and washes the washing water. At this time, the dirt of the to-be-cleaned object 9 which floated by the action of the detergent mist which is microparticles | fine-particles and high density | concentration is wash | cleaned effectively.

In addition, by using the blower 25 as a dry blower that blows air during the drying step of drying the dishes, a low-cost and compact dishwasher can be realized without requiring a dedicated blower.

As described above, in the present embodiment, the mist generating means 15 has a pretreatment step of dispersing the detergent mist of the fine particles to the object to be cleaned 9, and the blower device is output by the output of the temperature detecting means 23. 25).

As a result, the amount of mist generated and the filling of the mist into the washing tank can be assured irrespective of the room temperature or the water temperature of the water supplied, so that a high washing performance unprecedented can be obtained stably.

The blower drive capability in the preprocessing stroke is controlled by at least one of the detection temperature T0 of the temperature detection means at the start of operation and the detection temperature T1 of the temperature detection means after a predetermined time elapses from the start of operation. do. As a result, the amount of mist generated and the filling of the mist into the washing tank can be assured irrespective of the room temperature or the water temperature of the water supplied, so that a high washing performance unprecedented can be obtained stably.

In addition, when the detection temperature T0 of the temperature detection means at the start of operation is higher than the predetermined temperature, the mist generating means is driven after driving the blower for a predetermined time in the preprocessing stroke. In order to cool the washing tank when the temperature in the washing tank is high, the upward flow in the washing tank can be promoted to ensure the filling of the mist into the washing tank. You can get it.

Moreover, the blower of this invention is comprised by the dry blower which blows at the time of the drying process of drying the to-be-cleaned object. That is, since a dedicated blower is not required, a compact dish washing machine can be realized at low cost.

As described above, the dishwasher of the present invention can significantly improve the cleaning performance by having a pretreatment step of attaching the detergent mist of fine particles to the contaminants attached to the object to be cleaned. Moreover, stable cleaning performance can be obtained by controlling the drive of a blower by the detection temperature of a temperature detection means.

Since the washing | cleaning power of the dishwasher of this invention improves significantly, it can be used widely as a dishwasher etc. which wash | clean by spraying washing water etc. to a tableware.
