Description

  The present invention relates to a dishwasher for cleaning by irradiating washing water onto an object to be cleaned such as dishware.

  Conventionally, a general dishwasher has been configured as shown in FIG. Hereinafter, the configuration will be described.

  As shown in FIG. 5, the dishwasher body 1 is provided with a washing tub 2 inside, and water or hot water is supplied into the washing tub 2 by a water supply valve 3. A drainage hole 4 is provided at the bottom of the washing tank 2, and a washing pump 5 that is connected to the drainage hole 4 and is driven by a motor is attached. The washing pump 5 circulates washing water into the washing tank 2. doing. Further, the drain hole 4 is provided with a residue filter 6 for collecting the residue.

  In the above configuration, the cleaning water supplied into the cleaning tank 2 passes through the residual filter 6 and is sucked into the cleaning pump 5 and supplied from the cleaning pump 5 to the cleaning nozzle 7 provided at the inner bottom of the cleaning tank 2. The The washing water sprayed from the washing nozzle 7 circulates along a route that returns to the drain hole 4 again after washing the object (tableware) 8 to be washed. At this time, the residue or the like dropped off from the object to be cleaned 8 flows into the residue filter 6 together with the washing water, and the residue having a size that cannot pass through the residue filter 6 is collected by the residue filter 6.

  Further, a heater 9 for heating the cleaning water is provided between the cleaning nozzle 7 and the bottom of the cleaning tank 2, and an object to be cleaned 8 can be arranged orderly above the cleaning nozzle 7, so that the cleaning water is effective.

  However, with these configurations, it was not possible to wash all the stains washed in the dishwasher. In particular, it is not good for dishes that are directly heated and cooked with scorch. For example, gratin, chawanmushi, etc.

  Further, even those having a water particle generation mechanism were effective only for specific contamination.

  The present invention solves the above-mentioned conventional problems. In a state where a detergent solution having a concentration higher than the concentration of detergent during normal use is attached to an object to be cleaned in a state of reaching a certain temperature, the detergent components are easily activated. The object of the present invention is to greatly improve the cleaning performance by having a pre-treatment process for adhering to an object to be cleaned and allowing it to stand, so that it is possible to clean dishes that could not be removed in the past.

  In order to achieve the above-mentioned object, the present invention is configured such that an object to be cleaned such as tableware is accommodated in a cleaning tank, and a high-concentration detergent liquid is adhered to the object to be cleaned by the detergent liquid scattering means. The heating means for heating the high-concentration detergent liquid is provided, and the high-concentration detergent liquid is preliminarily heated before splashing.

  As a result, the detergent component is activated by having a pre-treatment process in which a detergent solution having a higher concentration than that in normal use is heated and attached to the object to be washed in a state where the detergent solution has reached a certain temperature. Since it can be easily adhered to the object to be cleaned, the cleaning performance can be greatly improved, and the dish stains that could not be removed conventionally can be cleaned.

  The dishwasher of the present invention heats a detergent solution having a concentration higher than that of normal use, adheres to the object to be cleaned in a state of reaching a certain temperature, and the object to be cleaned in a state where the detergent components are easily activated. By having a pre-treatment step of adhering to the substrate and leaving it to stand, the cleaning performance can be greatly improved.

  1st invention is equipped with the washing tank which accommodates to-be-washed objects, such as tableware, and the detergent liquid scattering means to which a high concentration detergent liquid adheres to a to-be-washed object, The said detergent liquid scattering means is a high concentration detergent liquid. It has a heating means to heat and is configured to heat the high-concentration detergent liquid in advance before splashing, and the detergent liquid with a higher concentration than the detergent concentration during normal use is heated and reaches a certain temperature By adhering to the object to be cleaned and adhering to the object to be cleaned in a state where the detergent components are easily activated, the cleaning performance can be greatly improved. Further, since the high-concentration detergent is used by heating in this pretreatment process and the temperature of the article to be cleaned is also increased, the time required for the water temperature increase in the next main cleaning process can be shortened. Furthermore, since the cleaning performance can be further improved by performing the main cleaning process from the high temperature cleaning water, the cleaning time can be shortened.

  In a second aspect based on the first aspect, the heating means controls the heating temperature of the high-concentration detergent liquid to a predetermined temperature, and is controlled at an optimum temperature for the activity of the detergent components. Therefore, it is possible to greatly improve the cleaning performance by leaving the detergent components attached to the object to be cleaned in a state where the detergent components are easily activated.

  3rd invention is equipped with the washing tank which accommodates to-be-washed objects, such as tableware, and the detergent liquid scattering means to which a high concentration detergent liquid is made to adhere to the to-be-washed object, The said detergent liquid scattering means has a warm air blowing means. It has a configuration in which high-concentration detergent liquid is sucked up and scattered in the form of a mist when hot air is blown, and when high-concentration detergent liquid is scattered, the temperature of the high-concentration detergent liquid can be raised by hot air The cleaning performance can be greatly improved by leaving the detergent components attached to the object to be cleaned while being easily activated.

  The fourth invention comprises a cleaning tank for storing objects to be cleaned such as tableware, and detergent liquid scattering means for adhering a high concentration detergent solution to the objects to be cleaned, and is cleaned with heated cleaning water at the beginning of the cleaning process. After the temperature of the object to be cleaned is raised in advance, the detergent liquid splashing means is operated so that a high-concentration detergent solution is attached to the object to be cleaned. Since the high-concentration detergent solution is attached by operating the liquid scattering means, the washing performance can be greatly improved by leaving the detergent component in a state where it is easily activated.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, the thing of the same structure as a prior art example attaches | subjects the same code | symbol, and abbreviate | omits description. Further, the present invention is not limited by this embodiment.

(Embodiment 1)
As shown in FIG. 1, as a pretreatment process of the cleaning process, the detergent liquid scattering means 13 scatters a high concentration detergent liquid in which the detergent is dissolved in a small amount of water into the cleaning tank 2, and the scattered high concentration liquid. A detergent liquid is attached to the object to be cleaned 8 and is provided in the cleaning tank 2. As shown in FIG. 2, the detergent liquid scattering means 13 includes a heating means 14 for heating the high concentration detergent liquid and a temperature detecting means 15 for detecting the temperature of the high concentration detergent liquid. The heating temperature is controlled to a predetermined temperature.

  The operation and action of the above configuration will be described. First, a standard amount of detergent is put in the detergent liquid scattering means 13, and a predetermined amount of water that becomes a high-concentration detergent liquid is supplied from the water supply valve 3 by a supply hose (not shown) to the detergent liquid scattering means 13. In this case, the predetermined amount of water supply is set by a water amount detection means (not shown) that detects the amount of water. However, the water supply valve 3 having a constant flow rate may supply water for a predetermined time. Further, another dedicated water supply valve other than the water supply valve 3 for supplying water into the cleaning tank 2 may be used.

  Next, the high concentration detergent liquid is heated by energizing the heating means 14 in the detergent liquid scattering means 13. At this time, the temperature detecting means 15 detects the temperature of the high-concentration detergent solution, and when the temperature reaches a predetermined temperature, the heating means 14 is deenergized and the ultrasonic vibrator 13a built in the detergent liquid scattering means 13 is operated. Then start scattering high concentration detergent solution.

  As a pretreatment process of the cleaning process, the high-concentration detergent liquid heated in the cleaning tank 2 is scattered from the detergent liquid scattering means 13, and the heated high-concentration detergent liquid is adhered to the object 8 to be cleaned. Leave in condition. A high concentration detergent solution chemically decomposes dirt adhering to the article 8 to be cleaned. Moreover, since the detergent component is further activated because it is heated to a predetermined temperature, it is advantageous for the decomposition of dirt.

  The temperature of the high-concentration detergent solution is a temperature at which the components of the detergent to which the object to be cleaned 8 adheres are likely to be activated. To do. On the other hand, if the soil is a protein, when the high-concentration detergent solution of high temperature is applied instantaneously, the protein changes, which is disadvantageous for cleaning performance. Therefore, the heating temperature is controlled so that the temperature does not exceed a certain level.

  In the main cleaning process after the pretreatment process, the conventional dishwasher is washed with respect to the dirt after the specific dirt is decomposed by the high-concentration detergent solution in the pretreatment process. Since the necessary amount of detergent has already been put into the washing tank 2, a normal amount of washing water is supplied by the water supply valve 3 to perform cleaning.

  In the dirt of the article 8 to be cleaned, there are some cases where the temperature and mechanical force (the momentum of jetting the washing water from the washing nozzle 7) are extremely high. In addition, dirt that has been decomposed in the pretreatment process cannot be cleaned by itself, and it can be reliably cleaned by temperature and mechanical force. However, the decomposition of the dirt by leaving it after the high-concentration detergent solution is attached in this pretreatment process is very effective for the kind of dirt that could not be removed conventionally.

  As described above, in the present embodiment, the detergent liquid scattering means 13 heats the detergent liquid having a concentration higher than the detergent concentration during normal use, and adheres to the object to be cleaned in a state of reaching a certain temperature. The cleaning performance can be greatly improved by having a pre-treatment process in which the component is allowed to be activated and attached to the object to be cleaned.

(Embodiment 2)
As shown in FIG. 3, the detergent liquid scattering means 16 scatters a high concentration detergent solution in which the detergent is dissolved in a small amount of water in the cleaning tank 2 as a pretreatment process of the cleaning process. A detergent liquid is attached to the object 8 to be cleaned, and is composed of a heating container 17, a detergent liquid storage container 18 for storing a high concentration detergent liquid, and a detergent liquid splashing portion 19, and as in the first embodiment. It is provided in the cleaning tank 2.

  A heating means 20 is disposed in the heating container 17, and the cleaning water (tap water) supplied to the inside of the heating container 17 is heated by the heating means 20 to be converted into steam and heated as a hot air by increasing its internal pressure. It sprays from the scattering part 19. Here, the heating container 17 is configured as hot air blowing means.

  The detergent liquid storage container 18 stores and stores a high concentration detergent liquid made of a predetermined amount of detergent and a predetermined amount of cleaning water (tap water). The high-concentration detergent liquid at this time may be directly charged with a detergent liquid prepared in advance by the user, or may be made with an automatic detergent charging device and a water supply valve provided in the device.

  The detergent liquid splashing portion 19 is composed of two nozzles 19 a and 19 b (parts with narrowed holes at the tip of the blowout) in the passage from the heating container 17 and the detergent liquid storage container 18. Other configurations are the same as those of the first embodiment.

  The operation and action of the above configuration will be described. In the initial pretreatment process of the cleaning process, the high-concentration detergent solution having a high temperature is scattered and attached to the object 8 to be cleaned, and left in that state, and then the cleaning process is performed in the main cleaning process. Since it is the same as the first embodiment, the description thereof is omitted.

  The washing water (tap water) supplied to the inside of the heating container 17 is heated by the heating means 20 in the heating container 17, and the detergent liquid storage container 18 is ejected by steam from the nozzle 19 a communicating with the heating container 17. The nozzle 19b leading to the negative pressure becomes negative pressure, and the high-concentration detergent liquid stored in the detergent liquid storage container 18 is sucked up. At this time, the high-concentration detergent liquid is sprayed into the cleaning tank 2 in the form of a mist as the steam is jetted. Further, the scattered high-concentration detergent liquid rises from the initial washing water depending on the temperature of the steam, and the high-concentration detergent liquid having a high temperature can adhere to the object 8 to be cleaned.

  As described above, in the present embodiment, the high-concentration detergent solution having a high temperature can be scattered and adhered to the object 8 to be cleaned, so that the detergent components are easily adhered to the object to be cleaned. By leaving it alone, the cleaning performance can be greatly improved.

  In the present embodiment, an example of hot air blowing by generation of steam using the heating container 17 has been described, but hot air may be blown by heating the blower and the blown air by a heating means.

(Embodiment 3)
As shown in FIG. 4, as a pretreatment process of the cleaning process, the detergent liquid scattering means 21 scatters a high concentration detergent liquid in which the detergent is dissolved in a small amount of water into the cleaning tank 2, and the scattered high concentration liquid. A detergent liquid is attached to the object to be cleaned 8 and is provided in the cleaning tank 2. This detergent liquid scattering means 21 does not have a heating function, but has only a function of scattering a high concentration detergent liquid. After the temperature is raised in advance, the detergent liquid scattering means 21 is operated so that the high-concentration detergent liquid adheres to the object 8 to be cleaned. Here, the detergent liquid scattering means 21 is configured such that the detergent water is securely covered after the detergent is introduced, and the washing water does not enter during normal washing water injection. Other configurations are the same as those of the first embodiment, and the same reference numerals are given and description thereof is omitted.

  The operation and action of the above configuration will be described. First, in the same manner as in the first embodiment, a standard amount of detergent is put in the detergent liquid scattering means 21, and a high-concentration detergent liquid is obtained from the water supply valve 3 by a supply hose (not shown) to the detergent liquid scattering means 21. Supply a predetermined amount of water.

  Next, as a pretreatment process of the cleaning process, first, a predetermined amount of cleaning water is supplied into the cleaning tank 2 by the water supply valve 3. The heater 9 is energized, the cleaning pump 5 is driven while heating, and the object 8 to be cleaned is heated and cleaned. At this time, the detergent liquid scattering means 21 is configured such that the washing water does not enter, so that the concentration of the detergent liquid does not become thin and does not flow out of the detergent liquid scattering means 21. When the cleaning water reaches a certain temperature, the driving of the cleaning pump 5 and the energization of the heater are stopped.

  At this time, an ultrasonic vibrator (not shown) built in the detergent liquid scattering means 21 is operated to cause the high-concentration detergent liquid to splash, adhere to the object to be cleaned 8, and leave for a predetermined time. At this time, since the high-concentration detergent liquid is adhered while the article to be cleaned 8 is heated in advance, the temperature of the high-concentration detergent liquid also rises. However, since the cleaning water adheres to the article 8 to be cleaned first, the concentration of the high-concentration detergent solution is lowered, so that the concentration is set in advance.

  Thereafter, the operation of performing the cleaning in the main cleaning process is the same as that in the first embodiment, and thus the description thereof is omitted.

  As described above, in the present embodiment, as the pretreatment process of the cleaning process, the cleaning liquid 21 is operated after the cleaning object 8 is first heated and the temperature of the article 8 to be cleaned is raised in advance. Since the high-concentration detergent liquid is adhered to the object 8 to be cleaned, the high-concentration detergent liquid can be scattered and adhered to the object 8 having a high temperature, and the detergent components are easily activated. Cleaning performance can be greatly improved by leaving the product to adhere to the object to be cleaned.

  As described above, the dishwasher according to the present invention heats a detergent solution having a concentration higher than the concentration of detergent during normal use, adheres it to the object to be cleaned in a state of reaching a certain temperature, and the components of the detergent are activated. Since it has a pre-treatment process that allows it to adhere to the object to be cleaned and leave it in an easy state, the cleaning performance can be greatly improved, so as a dishwasher that sprays cleaning water on the object to be cleaned such as tableware.
