Further, the conventional dishwasher has put the lotion into the bottom of the washing tank through the lotion input portion before the washing step is performed. At this time, the position at the bottom of the washing tank into which the lotion is applied is set to a position away from the heater.

Further, in the conventional washing machine, when the water is supplied to the predetermined water level in the washing step, the washing pump is started up substantially simultaneously with the energization of the heater. The dishwasher having the above-described configuration is disclosed in Japanese Laid-Open Patent Publication No. 2006-61450 (hereinafter referred to as "Patent Document 1").

Hereinafter, the configuration of the conventional dishwasher will be described with reference to Fig. 8 .

Figure 8 is a side cross-sectional view of a conventional built-in type dishwasher.

As shown in Fig. 8, in the conventional dishwasher, first, the user grips the handle portion 18 to pull the cleaning tank 3 forward from the body 1. Then, the object 7 to be washed or the like is stored in the cleaning tank 3 from the opening 2 provided above the washing tank 3.

Next, the user puts a predetermined amount of the lotion into the lotion input unit 14 disposed in the vicinity of the front surface of the washing tank 3. Thereby, the injected lotion is guided to a predetermined position at the bottom of the washing tank 3 each time.

Next, the user pushes the cleaning tank 3 to the original position, and closes the opening 2 by the lid 11.

Then, in the above state, the operation of the dishwasher is started. At this time, the dishwasher is operated by the washing pump 5 driven by the motor, and the washing water pressurized by the washing pump 5 is sprayed from the washing nozzle 6. Thereby, the washing and rinsing step of the object 7 to be washed is performed.

At this time, the washing water for washing the object to be washed 7 used in the washing and rinsing step is supplied through the water supply valve 15 attached to the rear of the main body 1, and is stored in the bottom of the washing tank 3 Department 4. Further, the auxiliary water tank 16 guides the washing water stored in the water storage unit 4 at the bottom of the washing tank 3 to the water level detecting device 20 including the washing water level detecting device 20a and the overflow water level detecting device 20b via the leftover vegetable collecting unit 10. . Further, the washing water level detecting device 20a is for detecting that the amount of washing water that has become the reference is accumulated in the washing tank 3. On the other hand, the overflow water level detecting device 20b is for detecting the cleaning tank If the water level in 3 becomes higher than the predetermined water level, there is a possibility of overflow.

In addition, the leftovers collection unit 10 is provided as a recess at the lowest position in the water storage unit 4 on the downstream side of the flow of the washing water in the bottom portion 5 of the washing tank 3. Further, the leftovers collection unit 10 has a detachable leftovers recovery filter (not shown) and a coarse mesh drainage filter (not shown).

Further, the control device 21 is provided in the main body 1, and controls various electronic components such as the washing pump 5, the heater 8, the water supply valve 15, and the blower fan 17, and performs various steps of washing, rinsing, and drying.

Hereinafter, the operation of the washing step of the conventional dishwasher will be briefly described.

First, the user sets the operation stroke by the input device 19. Thereby, the control device 21 starts the operation of the dishwasher in accordance with the setting of the input device 19. At this time, when the user sets the standard stroke by the input device 19, the control device 21 correctly supplies water to the washing tank 3 by the detection information of the washing water level detecting device 20a up to a certain amount of water (for example, the reference water level).

Next, the control device 21 operates the washing pump 5 for a predetermined time. Thereafter, the water supply valve 15 is energized for a predetermined time, and the makeup water is added to the washing tank 3. Thereby, the amount of the washing water in the washing tank 3 is adjusted to the amount necessary for washing and sufficient water.

Next, when the water supply is completed, the control device 21 energizes the heater 8 and the washing pump 5 to be turned "ON". As a result, the lotion which has been previously introduced into the predetermined position at the bottom of the cleaning tank 3 is efficiently dissolved, and the washing water is sprayed from the washing nozzle 6 to wash the object 7 to be washed.

At this time, the dissolution rate of the lotion which is introduced into the bottom of the washing tank 3 is promoted together with the temperature of the washing water.

At this time, the washing pump 5 is constituted by a motor (not shown) that can rotate in the forward and reverse directions. When the cleaning pump 5 rotates in the normal direction, the original operation of the washing pump (the circulating operation of the washing water) is performed, and when the washing is performed in the reverse direction, the washing water in the washing tank 3 is discharged. Move to the drain pump outside the machine.

The heater 8 is provided in the water storage unit 4 at the bottom of the washing tank 3, and is configured to heat the washing water stored in the water storage unit 4 in the washing tank 3. Further, the periphery of the heater 8 is surrounded by, for example, a heater protection member 9 made of stainless steel or the like, and even if a small object such as a chopstick or a spoon falls, it can be directly protected without coming into contact with the heater 8. Furthermore, it also has an effect on preventing leftovers from getting stuck.

Further, as shown in FIGS. 1 and 2, the lotion input unit 14 is integrally provided at the upper position of the heater protection member 9, for example, in the dish basket 13c in which the small items such as chopsticks or spoons are placed as described above. Further, the lotion input unit 14 induces the injected lotion onto the heater 8. Therefore, the lotion input portion 14 is disposed at a position upstream of the flow of the washing water flowing in the bottom portion of the washing tank 3. Further, generally, the bottom portion of the cleaning tank 3 has a mortar shape, and the periphery of the inner bottom portion becomes high. Therefore, the washing water flows from the periphery of the bottom of the washing tank 3 toward the leftovers collecting portion 10. That is, the peripheral side of the bottom of the cleaning tank 3 It is on the upstream side of the flow of the above-mentioned washing water. Thereby, the contact of the put-in lotion with the to-be-washed material 7 provided in the dish basket 13 can be avoided. Further, the injected lotion can be guided upstream of the heater 8 through the lotion input unit 14.

Further, as shown in FIGS. 1 and 2, the water storage unit 4 described above is provided at the bottom of the cleaning tank 3 to store the washing water. The position of the water storage unit 4 is a position at the middle of the path of the cleaning pump 5 that connects the heater 8 and the cleaning tank 3 . Further, the water storage unit 4 is provided with leftovers having a leftovers recovery filter (not shown) for collecting leftovers washed from the laundry 7, and a drainage filter (not shown) of a coarse mesh. Collection unit 10. Further, the leftovers collecting unit 10 also serves as a drain port from the washing tank 3 to the washing pump 5.

The water supply valve 15 is provided at the rear of the body 1. When the water supply valve 15 is actuated, the control device 21 supplies tap water or the like into the washing tank 3 as a washing water through a pipe.

The auxiliary water tank 16 is, for example, a side surface provided near the bottom of the rear of the washing tank 3. The water level detecting device 20 is notified to the leftovers collecting unit 10 (drain port) by the piping provided in the auxiliary water tank 16. The water level detecting device 20 has a washing water level detecting device 20a and an overflow water level detecting device 20b. Further, the washing water level detecting device 20a detects that the washing water to be the reference amount has been stored in the washing tank 3 as a predetermined detected water level (for example, the reference water level). On the other hand, the overflow water level detecting device 20b detects the possibility that there is overflow when the water level in the washing tank 3 becomes higher than a predetermined water level.

A temperature detecting unit (not shown) is fixedly disposed outside the bottom of the washing tank 3 to detect the temperature of the washing water in the washing tank 3.

The control device 21 is provided in the main body 1, and controls various electronic components such as the washing pump 5, the heater 8, the water supply valve 15, and the blower fan 17, so that the tableware can be cleaned. Furthermore, the control device 21 controls the above-mentioned input information such as the power-on, power-off, stroke selection, and operation start input from the input device 19, detection information from the water level detecting device 20 or the temperature detecting device, and commands from the control program. Various electronic parts are used to carry out the steps of the washing step, the rinsing step and the drying step.

As described above, the dishwasher of the present embodiment is constructed.

Hereinafter, the operation and action of the dishwasher according to the embodiment will be described. Further, since the basic operation and action of the dishwasher are the same as those of the conventional dishwasher, the description thereof is omitted.

First, the user sets the laundry 7 such as tableware to the cutlery basket 13 before the operation of the operation of the dishwasher. Then, the lotion is introduced into the heater 8 on the front side 3a side of the cleaning tank 3 through the lotion input unit 14 shown in Figs. 1 and 2 .

Then, the control device 21 starts the washing operation of the dishwasher in accordance with the input from the input device 19 by the user.

Next, the control device 21 first activates the washing pump 5, and drains the washing water in the washing tank 3 to a state of no water. At this time, the washing pump 5 operates as a drain pump. After that, the water supply valve 15 is operated, and the water supply is detected until the washing water level detection device 20a of the water level detecting device 20 detects the washing water, and the water supply is performed until the predetermined water level in the washing tank 3 is reached. Then, when the washing water level detecting device 20a detects the detected water level which becomes the reference water level, the control device 21 completes the water supply based on the detected information (mainly for water). At this time, the detected water level which becomes the reference water level in the washing tank 3 is set lower than the water level of the washing water at the time of the washing in the washing step which is performed later.

Next, the control device 21 also turns on the water level of the washing water at the time when the water level of the washing water is lower than the cleaning step, and energizes the heater 8 to be turned ON, and the operation is performed for a predetermined time. Further, at this time, the washing pump 5 is not operated. Thereby, the temperature of the washing water accumulated in the washing tank 3 rises. Then, as the temperature of the washing water rises, the dissolution of the lotion which is introduced into the upstream side by the flow of the washing water on the heater 8 through the lotion input unit 14 is promoted. At this time, if the temperature of the washing water does not reach a predetermined value (for example, from 40 ° C to 60 ° C) within a predetermined time, the heater 8 continues to be energized until the temperature of the washing water becomes a predetermined value. The reason for this is that the maximum active temperature (optimum temperature) of the enzyme component contained in the lotion used in the dishwasher is approximately 40 ° C to 60 ° C. That is, by setting the temperature of the washing water to 40 ° C to 60 ° C, the activity of the enzyme of the lotion is increased, and the dish stain which is decomposed by the enzyme can be effectively washed.

When the temperature of the washing water is equal to or higher than the predetermined temperature, the control device 21 turns off the heater 8 to complete the heating of the washing water. Then, for example, the cleaning pump 5 is operated in an intermittent operation under the conditions of 5 seconds of being turned off (ON) for 5 seconds to be turned off (OFF), and preliminary washing is performed. Thereby, the washing agent is sprayed with a high concentration and high-temperature washing water to the object 7 to be washed. Further, in this case, the operation of the washing pump 5 does not necessarily have to be performed in an intermittent operation, and the operation may be performed in a continuous operation.

At this time, the amount of water in the washing tank 3 at the time of cleaning after the washing step after the washing is prepared must take into consideration the food contamination process attached to the object 7 to be washed. It is set by the degree of foaming or the like generated by the lotion component. Thereby, the sound of the air entrapped or the influence on the performance surface can be reduced by a series of washing operations.

Therefore, in the dishwasher of the embodiment, the control device 21 operates the washing pump 5 for a predetermined period of time. Thereafter, the water supply valve 15 is energized for a predetermined time as in the prior art, and the makeup water is added to the cleaning tank 3. Thereby, the amount of water in the washing tank 3 in the washing is adjusted to a necessary and sufficient amount of water during the washing in the washing step.

Thereafter, washing is performed in the washing step in the same manner as in the prior art, and is transferred to the rinsing step of the next step.

The operation of the washing step of the dishwasher of the present embodiment is carried out as described above.

That is, in the washing machine of the present embodiment, even if the temperature of the washing water supplied to the washing tank 3 is low in the washing step, the washing pump 5 is not operated, first by washing the water The heater 8 is heated to sufficiently dissolve the detergent to be supplied to the washing water. Therefore, from the beginning of the washing exercise, the washing liquid 6 is washed from the washing nozzle 6 with the high-concentration and high-temperature washing water, and the washed matter 7 can be washed.

Further, in the present embodiment, in particular, the introduced lotion is sufficiently dissolved in the less-washed water in the washing tank 3 before the additional water is supplied. As a result, the washed object 7 can be washed with a higher concentration and high-temperature washing water from the start of the washing operation.

Further, in the dish washing of the present embodiment, the heater 8 on the upstream side of the flow of the washing water flowing in the bottom portion of the washing tank 3 is washed. The agent input unit 14 is provided with a lotion. Then, the washing water passes through the vicinity of the heater 8 in the high temperature state after heating from the upstream to the downstream together with the operation of the washing pump 5. Thereby, the dissolution of the lotion is further promoted. Therefore, the applied lotion can be more fully dissolved in the less wash water before the additional makeup water. As a result, from the start of the washing operation, the washing water having a higher concentration and a higher temperature can be ejected from the washing nozzle 6 to wash the washed matter 7.

Further, in the dishwasher of the present embodiment, the lotion is introduced into the vicinity of the heater 8 through the lotion input unit 14. Thereby, the dissolution rate of the washing agent toward the washing water is rapidly increased by the heated washing water. As a result, even if the lotion is put in a little more than the rated amount, the case where the lotion is not completely dissolved in the washing water does not occur.

As described above, according to the dish washing of the embodiment, even if the temperature of the water in the washing tank 3 is low, the washing pump 5 is not operated, and the introduced lotion can be sufficiently dissolved. Therefore, from the beginning of the washing operation, the washing water of a higher concentration and a higher temperature can be washed.

That is, according to the configuration of the dishwasher of the present embodiment, high-concentration and high-temperature washing water can be obtained before the cleaning pump 5 is operated. In addition, the high-concentration and high-temperature washing water can be sprayed to the laundry such as the tableware for a predetermined period of time before being mixed with the washing water contaminated by the washing of the washed matter. Thereby, the dishwasher having a higher washing effect than the conventional dishwasher can be realized with the same washing amount (or even the same amount of water).

(Embodiment 2)

Hereinafter, the dishwasher of the second embodiment of the present invention is used. The configuration will be described using FIG. 3.

Fig. 3 is a side sectional view showing the dishwasher of the second embodiment of the present invention.

As shown in Fig. 3, the dishwasher of the present embodiment differs from the first embodiment in that the lotion input unit 14 is disposed such that the lotion falls between the heater 8 and the leftovers collecting unit 10. Other configurations, operations, and operations are the same as those in the first embodiment, and thus the description thereof is omitted.

That is, as shown in Fig. 3, the lotion input portion 14 of the dishwasher of the present embodiment is integrally provided in a cutlery basket 13c in which small objects such as chopsticks or spoons are placed. Further, the lotion input unit 14 is disposed at a position on the downstream side of the flow of the flowing water flowing through the bottom portion 5 in the washing tank 3. Specifically, the lotion input unit 14 is provided in the cutlery basket 13c so that the lotion falls between the heater 8 and the leftovers collecting unit 10. Thereby, the injected lotion is guided to the downstream of the heater 8 through the lotion input unit 14.

In other words, the dishwasher of the present embodiment is similar to the dishwasher of the first embodiment, and the temperature of the washing water supplied to the washing tank 3 can be sufficiently dissolved even when the temperature of the washing water supplied to the washing tank 3 is low. Specifically, the washing pump 5 is not operated, and a small amount of washing water in the washing tank 3 before the additional water supply is heated by the heater 8 can be input between the heater 8 and the leftovers collecting portion 10. The lotion is fully dissolved. Therefore, from the beginning of the washing operation, the washing water having a higher concentration and a higher temperature can be sprayed from the washing nozzle 6 to wash the object 7 to be washed.

Further, in the dishwasher of the present embodiment, the lotion is disposed downstream of the flow of the washing water through the lotion input portion 14 at the inner bottom portion of the washing tank 3. The vicinity of the heater 8 on the side (the side of the leftovers collection unit 10). Then, together with the operation of the washing pump 5, the high-temperature and high-concentration washing water generated by one of the washing agents can be introduced into one breath. Therefore, the washing water is sprayed from the washing nozzle 6, and the washed matter 7 can be washed from the washing water having a high washing power.

Further, the configuration of the lotion input unit may be provided by using the present embodiment and the first embodiment. Thereby, both the upstream side and the downstream side of the flow of the washing water can generate high-temperature and high-concentration washing water. As a result, it is possible to further improve the detergency.

Thereby, the heated washing water can smoothly enter and exit the lotion receiving portion 47, so that the lotion S is dissolved as a lotion liquid, and the lotion liquid can be easily discharged. The water-passing portion 47d of the lotion receiving portion 47 is provided at a position lower than the water-flow portion 47c at the position of the holding portion 47a of the lotion receiving portion 47. Thereby, similarly to the water-flow part 47c, the entrance and exit of the washing water and the lotion liquid can be easily performed through the water-passing portion 47d.

In the present embodiment, the example in which the entire holding portion 47a and the water flowing portion 47c of the lotion receiving portion 47 are formed above the heater 37 will be described. However, the present invention is not limited thereto. For example, at least the water flowing portion 47c may be formed above the heater. In this case, it is desirable that many portions of the holding portion 47a of the lotion receiving portion 47 are formed above the heater 37.

Moreover, it is desirable that the lotion receiving portion 47 is configured to take the entry and exit of the washing water as smoothly as possible. Therefore, for example, a plurality of inlet and outlet portions may be provided as the water flowing portion 47c of the lotion receiving portion 47 and the water passing portion 47d. At this time, in particular, it is preferable that the height of the water flowable portion 47c and the water passing portion 47d are changed. Thereby, the washing water, the lotion liquid, and the like can be convected between the lotion receiving portion 47 and the outside and can be effectively utilized. As a result, the dissolution of the lotion can be further promoted.

Further, the standing portion 47b of the unnecessary detergent holding portion 47 may be vertical, and the holding portion 47a may be formed to make it difficult for the applied lotion S to overflow. Further, the upper end 47b1 of the upright setting portion 47b may be provided at a position higher than a predetermined detection water level (for example, a reference water level).

As described above, the dishwasher of the present embodiment is constructed.

Hereinafter, the operation and action of the dishwasher according to the embodiment will be described. Further, since the basic operation and action of the dishwasher are the same as those of the conventional dishwasher, the description thereof is omitted.

First, the user sets the object to be cleaned such as tableware to the cutlery basket 32 before the operation of the dishwasher is started. Then, the lotion is introduced into the lotion receiving portion 47 from the lotion input unit 48 shown in Figs. 4 and 5 .

Then, the control device 45 is based on the user from the input device 19 Enter and start the cleaning operation of the dishwasher.

Next, the control device 45 initially activates the washing pump 36, and drains the washing water in the washing tank 31 to a state of no water. At this time, the washing pump 36 operates as a drain pump. Thereafter, the water supply valve 42 is operated, and the water level detecting device 44 supplies water until the predetermined water level in the washing tank 31 from the water-free state to the detection of the washing water. Then, when the water level detecting device 44 detects the detected water level which becomes the reference water level, the control device 45 completes the water supply (main water supply) based on the detected information. At this time, the detected water level of the reference water level which is the washing water in the washing tank 31 is set to be lower than the washing water level at the time of the washing which is performed after the washing step which is performed later.

By the control device 45, when the water level is lower than the water level at the time of washing in the washing step, the heater 37 is energized to start (ON), and the operation is performed for a predetermined time. Further, at this time, the cleaning pump 36 is not operated. Thereby, the temperature of the washing water accumulated in the washing tank 31 rises.

In this case, in the present embodiment, the pre-running lotion is provided to the lotion receiving portion 47. Moreover, as shown in FIG. 7, the lotion receiving portion 47 is a position which is provided above the heater 37 and is lower than the detection water level (for example, the reference water level) of the washing water. Therefore, the washing water heated by the heater 37 rises due to the convection phenomenon. At this time, the lotion which is supplied to the lotion receiving portion 47 is exposed to the convective high water temperature. As a result, the temperature of the washing water rises, and the dissolution of the lotion held by the washing agent holding portion 47 on the upstream side of the flow of the washing water on the heater 37 is promoted. As a result, a high-temperature and high-concentration lotion liquid can be obtained as washing water in a short time. At this time, when the temperature of the washing water does not reach the predetermined value (for example, from 40 ° C to 60 ° C) within a predetermined time, The heater 37 is continuously energized until the temperature of the washing water becomes a predetermined value. This reason is as explained in the first embodiment.

When the temperature of the washing water is equal to or higher than the predetermined temperature, the control device 45 turns off the heater 37 to complete the heating of the washing water. Then, the cleaning pump 36 is operated in an intermittent operation for a period of, for example, 5 seconds to be turned ON for 5 seconds to perform preliminary cleaning. As a result, the washing agent 46 is sprayed with a high concentration and high temperature washing water. In this case, the operation of the cleaning pump 36 does not necessarily need to be operated in an intermittent operation, or may be operated in a continuous operation.

At this time, the amount of water in the washing tank 31 at the time of cleaning after the preliminary washing is set in consideration of the food contamination and the foaming caused by the lotion component adhering to the object 46 to be washed. Thereby, the sound of entrained air or the influence on the performance surface can be reduced by a series of washing operations.

Therefore, in the dishwasher of the present embodiment, the control device 45 operates the cleaning pump 36 for a predetermined period of time. Thereafter, in the same manner as in the prior art, the water supply valve 15 is energized for a predetermined time, and the washing water is added and added to the washing tank 31. Thereby, during the cleaning of the washing step, the amount of water in the washing tank 31 in the washing is adjusted to a necessary and sufficient amount of water.

Thereafter, washing is performed in the washing step in the same manner as in the prior art, and is transferred to the rinsing step of the next step.

By the above, the operation of the washing step of the dishwasher of the present embodiment is carried out.

That is, the dishwasher of the embodiment is in the washing step In the case where the temperature of the water supplied to the washing water in the washing tank 31 is low, the washing pump 36 is not operated. First, the washing water is heated by the heater 37, so that the washing agent can be washed. The water is fully dissolved. Therefore, at the beginning of the cleaning operation, the high-concentration and high-temperature washing water is sprayed from the washing nozzle 35, and the washed matter 46 can be washed.

Further, in the present embodiment, in particular, the applied lotion is sufficiently dissolved in the small amount of washing water in the washing tank 31 before the additional water is supplied. As a result, from the start of the washing operation, the washed material 46 can be washed with a higher concentration and higher temperature washing water.

Further, in the dishwasher of the present embodiment, the lotion receiving portion 47 holding the lotion is disposed in the vicinity of the heater 37. Specifically, the lotion receiving portion 47 is disposed on the opposite side of the leftovers recovery portion 41, and the heater 37 is on the upstream side in the flow direction of the washing water. With this configuration, the washing water passes through the vicinity of the heater 37 in the high temperature state after heating from the upstream to the downstream together with the operation of the cleaning pump 36. Thereby, the dissolution of the lotion is further promoted. Therefore, the applied lotion can be sufficiently dissolved in the less wash water in the washing tank 31 before the additional makeup water. As a result, from the start of the washing operation, the washing water of a higher concentration and higher temperature can be ejected from the washing nozzle 35 to wash the laundry 46.

Further, the lotion receiving portion 47 is provided with a gradient from the fan case 40 at the time of washing water jetting. Therefore, the dissolution of the lotion can be further promoted by the flow of the washing water flowing through the gradient. Therefore, even when the washing dose is larger than the predetermined value, or the lotion which is difficult to dissolve, or the dissolution condition of the lotion is not good, it is possible to flow into the lotion by, for example, a permeation gradient. The agitating effect or the like by the washing water of the receiving portion 47 effectively dissolves the lotion and improves the washing performance.

As described above, according to the configuration of the dishwasher of the present invention, before the cleaning pump 36 is operated, a small amount of washing water is heated to a suitable temperature to obtain a high-concentration and high-temperature washing water. Further, the pure, high-concentration, high-temperature washing water before being mixed with the washing water contaminated by the washing of the washed matter can be ejected to the laundry 46 such as a tableware for a predetermined period of time.
