Description

Steam spray dishwasher with rinsing impeller}

The present invention relates to a steam injection dishwasher using a rinse impeller that connects a steam pipe to the rinse water pipe of a dishwasher and uses the rinse impeller through which rinse water is ejected as a steam outlet.

Dishwashers place dishes in a washing tank and clean them by washing and rinsing. The supply timing of hot and cold water required for dishwashing and rinsing, pump, washing water and rinsing water supply and heating, and drainage control are controlled through the control unit according to water temperature and level detection. In a dishwasher, a rinsing impeller and a washing impeller are located around the washing tank. The water supplied to the rinsing impeller and the washing impeller is divided into rinsing water and washing water, and the water stored in the rinsing water tank and the washing water tank is pumped by a rinsing pump and a washing pump and supplied to the washing tank. The water supply pipe is divided into a rinse water pipe and a wash water pipe, and a rinse pump is installed in the rinse water pipe and a wash pump is installed in the wash water pipe to supply the rinse water and wash water necessary for rinsing and cleaning. Dishwashers are designed to heat room temperature direct water into hot water for efficient washing and rinsing of dishes. The heated water is used only for washing and rinsing dishes, so its use for other purposes is limited. Meanwhile, Patent Document 1 proposes a steam dishwasher that installs a separate steam generator in the dishwasher to supply steam to increase the washing effect and circulates the steam inside the washing tank to improve washing efficiency. Meanwhile, a dishwasher with a steam function generally has a steam outlet on the side inside the washing tank. As a result, contaminants removed from the dishes during washing stick to the steam outlet, blocking or reducing the steam discharge area, thereby reducing steam transmission. Additionally, since the steam outlet must be cleaned separately, the cleanability of the product is significantly reduced. In addition, since the wash water inside the wash sump, where contaminants flow, is used as steam water, there is a problem that the cleanliness of the steam delivered to the dishes is significantly reduced. Accordingly, contaminants falling from the dishes block the steam outlet, thereby preventing a decrease in steam transmission power. Contaminants adhering to the steam outlet can be removed without the user having to clean them separately, while also preventing the steam from being removed due to the inflow of foreign substances. New proposals are being sought to solve the problem of poor cleanliness.

Figure 3 is a detailed view of part 'A' of Figure 2, and is an example showing the main parts of a steam injection dishwasher system using a rinsing impeller.
Figure 4 is a flow chart showing the steam cleaning process of a steam injection dishwasher system using a rinse water impeller according to an embodiment of the present invention.

Hereinafter, a 'steam injection type dishwasher using a rinsing impeller' according to an embodiment of the present invention will be described as follows.

Figure 1 is an example of an existing dishwasher system. As shown in FIG. 1, the dishwasher 100 places dishes in the washing tank 110 and cleans them by washing and rinsing. The supply timing of hot and cold water required for dishwashing and rinsing, pump, washing water and rinsing water supply and heating, and drainage control are controlled through a control unit (not shown) according to water temperature, water level detection, etc.

In the dishwasher 100, a rinsing impeller 120 and a washing impeller 130 are located around the washing tank 110. The water supplied to the rinsing impeller 120 and the washing impeller 130 is divided into rinsing water and washing water, and the water stored in the rinsing water tank 140 and the washing water tank 150 is supplied to the rinsing water pump 160 and the washing water. It is pumped with a pump 170 and supplied to the washing tank 110.

In this way, the pipe is divided into a rinse water pipe and a wash water pipe. A rinse water pump 160 is installed in the rinse water pipe, and a wash water pump 170 is installed in the wash water pipe, so that the rinse water and wash water required for rinsing and cleaning are installed. It is supplied to the washing tank 110 or the rinsing pump 160 in the rinsing water pipe can supply heated hot water from the rinsing water tank 140 to the washing water tank 150 through the rinsing impeller 120.

Here, the unexplained symbol 142 denotes a rinse water heater, and 152 denotes a wash water heater. 180 is a water supply connection, and 181 is a water valve installed at the water supply connector to open and close the water supply port.

Meanwhile, in the existing dishwasher system, a method of improving washing efficiency by circulating steam inside the washing tank is applied to increase dish washing effect and efficiency. For example, a method is being applied in which a steam outlet is provided on the side of the washing tank, and steam is supplied directly to the washing tank through a separate steam generator to increase the cleaning effect, and the steam is circulated inside the washing tank to improve cleaning efficiency.

However, in the case of the existing steam-type dishwasher system, contaminants removed from the dishes during washing stick to the steam outlet, blocking or reducing the steam discharge area, thereby significantly reducing the steam delivery power.

Additionally, since the steam outlet must be cleaned separately, the cleanability of the product is significantly reduced.

In addition, since the wash water inside the wash sump, where contaminants flow, is used as steam water, there is a problem that the cleanliness of the steam delivered to the dishes is significantly reduced.

Accordingly, the present invention prevents a phenomenon that appears to be a problem in existing steam-type dishwasher systems, that is, a phenomenon in which steam transmission power is reduced by contaminants removed from dishes blocking the steam outlet, and allows the user to perform separate cleaning. We present a steam injection dishwasher with a rinsing impeller that can remove contaminants stuck to the steam outlet without using a rinsing impeller and improves the problem of deterioration of steam cleanliness due to the inflow of foreign substances.

A steam injection type dishwasher using a rinsing impeller according to an embodiment of the present invention will be described in detail with reference to the attached drawings FIGS. 2 and 3 as follows.

Figure 2 is an example of a steam injection dishwasher system using a rinse impeller according to an embodiment of the present invention. Figure 3 is a detailed view of part 'A' of Figure 2, and is an example showing the main parts of a steam injection dishwasher system using a rinsing impeller.

As shown in Figures 2 and 3, the impeller-driven steam injection dishwasher 100 according to the present invention is equipped with a rinse water tank 140 and a wash water tank 150 for storing water for washing dishes. It can be configured.

In addition, the rinse impeller 120 and the rinse water pump 160 are directly connected through the water pipe 210 so that the water stored in the rinse water tank 140 is ejected through the rinse impeller 120. It can be.

Then, water from the rinse water tank 140 is supplied through the steam generator 300, heated to generate steam, and the steam is sent to the water pipe 210 via the steam flow path 320, and finally the rinse impeller ( 120) may be configured to eject steam.

In addition, a steam pipe 320, one end of which is connected to the water pipe 210 through a branch pipe 310, is connected to the water pipe 210 to flow the steam generated from the steam generator 300 and introduce steam into the water pipe 210. It can be configured to include.

In addition, as shown in FIG. 3, the steam generator 300 is connected to the steam pipe 320 at one end and has a flow path 330 for receiving steam water at the other end, so that the flow path 330 It may be composed of a heating chamber 340 having a hollow space that receives and receives steam water from. Additionally, the heating chamber 340 may be provided with a steam heater 341 installed inside the heating chamber 340.

In addition, the flow path 330 of the steam generator 300 further includes a steam water supply pump 331 for supplying steam water to the steam generator 300, and the steam generator 300 is configured to heat the steam generator 300. It may be configured to further include a full water level sensor 342 that detects the full water level of the steam water filled in the chamber 340.

In addition, the steam water supplied to the heating chamber 340 through the flow path 330 may be configured to use the rinse water stored inside the rinse water tank 140.

Through this, the rinse water inside the rinse water tank 140 is always maintained in a clean state, and clean steam can be sprayed on the dishes through the rinse impeller 120 to improve the cleanliness of the dishes.

That is, the water storage tank is divided into a rinse water tank 140 and a wash water tank 150, and in preparation for washing, water from the rinse water tank 140 is sprayed through the rinse impeller 120 and a wash water tank connected to the wash sump. The process of moving to (150) is performed, and contaminants removed after washing the dishes accumulate in the washing sump and contaminants may flow into the washing water tank (150) connected to the washing sump, but the rinsing water inside the rinsing water tank (140) Since it always remains clean, it can be advantageous in generating clean steam when used as steam water.

In general, in the case of commercial dishwashers, the rinse water is heated at a flow rate of 15.5L with a 3kW heater, so the water temperature rise and resilience are superior to that of wash water heated at a flow rate of 26.5L with a 1kW heater. Rinse water is used as steam water and the rinse water pipe is used. By using it as a steam pipe, you can effectively improve the temperature maintenance of steam and the ability to deliver dishes.

In addition, as shown in FIG. 3, the rinsing water for washing dishes is allowed to flow back toward the steam pipe 320 through the opening and closing device 350 installed between the branch pipe 310 and the steam pipe 320. It may be configured to block and allow the steam generated from the steam generator 300 to flow into the water pipe 210 through the branch pipe 310.

Through this, it is possible to prevent water ejected from the high-pressure rinse water pump 160 from flowing back into the steam generator 300 when moving to the water pipe 210, and to prevent foreign substances and foreign substances from flowing into the steam pipe 320. It is possible to effectively block the inflow of water.

In addition, the opening and closing device 350 may preferably be configured with a single wafer check valve 351, as shown in FIGS. 2 and 3. When the single wafer check valve 351 is applied as the switch 350, water remaining in the branch pipe 310 and the steam pipe 320 can be minimized, and steam can be smoothly moved to the water pipe 210. You can do it.

In other words, the single wafer check valve 351 prevents the water ejected from the high-pressure rinse water pump 160 from flowing back to the steam pipe 320, and induces the opening of even low-pressure steam in the direction of the water pipe. As it operates, it induces steam to easily flow to the water pipe 210.

On the other hand, when applying a valve other than the single wafer check valve 351, the valve lever must be controlled when opening and closing the valve, and this requires separate fully automatic control, which increases the process material cost to provide this, and when fully automatic control is performed, the valve lever must be controlled. Since it is difficult to respond to steam leakage due to malfunction and backflow of steam ejected from the steam generator 300, there are safety problems. Therefore, the single wafer check valve 351 can be selected as an effective valve constituting the opening and closing device 350.

In addition, as shown in FIG. 3, the branch pipe 310 has a diameter D2 of the connection portion from the steam pipe 320 to the water pipe 210, which is the longitudinal diameter D1 of the steam pipe 320. It is preferable to form an expansion part 311 that is expanded compared to.

In this way, when the diameter D2 of the connection part from the steam pipe 320 to the water pipe 210 is formed as an expanded pipe 311 expanded compared to the longitudinal diameter D1 of the steam pipe 320, the rinse water pump ( 160) By minimizing the amount of water remaining in the branch pipe 310 during operation, it is possible to induce steam to move smoothly toward the water pipe 210 without being affected by residual water.

That is, the end of the steam pipe 320 is configured to be open at a certain angle rather than vertically and is connected to the water pipe 210, so that the water present in the water pipe 210 is sprayed after the rinse water pump 160 is operated. It is prevented from remaining in the connection part of the engine 310, and the steam flow toward the rinsing impeller 120 is smoothly induced.

In addition, as shown in FIG. 3, the steam pipe between the steam generator 300 and the opening and closing device 350 of the steam pipe 320 is preferably formed with an S trap 321. In this way, when the steam pipe between the steam generator 300 and the opening and closing device 350 of the steam pipe 320 is formed with the S trap 321, the lowest height of the S trap 321 is that of the branch pipe 310. Since it can be configured to be placed in a position higher than the maximum height, the backflow phenomenon of water when the rinse water pump 160 operates can be blocked primarily through the switch 350, and then secondarily through the S trap 321. You can block it.

Accordingly, when the rinse water pump 160 is operated, it is possible to prevent the rinse water from flowing back through the steam pipe opening and closing device into the steam pipe and the steam generator, and smoothly induce steam movement.

In addition, the rinse water tank 140 is equipped with a full water level sensor (not shown) to detect the maximum water level and a temperature sensor (not shown) to detect the temperature of the rinse water, and the minimum height (H2) of the connection part of the branch pipe 310 ) is preferably located at a position higher than the maximum water level (H1) of the rinse water tank 140 detected by the full water level sensor.

In this way, when the minimum height (H2) of the connection part of the branch pipe 310 is configured to be located at a position higher than the maximum water level (H1) of the rinse water tank 140, after the rinse water pump 160 operates, the rinse water pipe It is located at a higher level than the head height of the residual rinse water existing within (210), and through this, when the steam generated in the steam generator 300 flows toward the rinse impeller 120 through the rinse water water pipe 210. It is possible to induce smooth movement of steam. Here, the rinse water pump 160 is preferably of an open type that opens the internal pipe in the operation stop mode.

In addition, after the rinse water tank 140 is heated to the steam water supply set temperature, it may be configured to include a control unit (not shown) that controls the supply of steam water by allowing the operation of the steam water supply pump 331.

Through this, the rinse water is heated by the rinse water heater 142 in the rinse water tank 160 up to the steam feed water set temperature, and the rinse water in a state of primary heating up to the steam feed water set temperature is sent to the steam generator 300. can be supplied.

Therefore, when the rinse water tank 140 is heated to the steam water supply set temperature and the control unit is set to control the steam water supply by allowing the operation of the steam water supply pump 331, the steam generator 300 The durability of the steam can be improved, and steam can be quickly generated and then supplied to the rinsing impeller 120.

Additionally, the control unit may be set to stop the operation of the rinse water pump 160 when the steam heater 341 of the steam generator 300 is operating.

In this way, when the control unit is set to stop the operation of the rinse water pump 160 when the steam heater 341 of the steam generator 300 is operating, the rinse water and steam commonly used in the water pipe 210 mixing can be minimized and mixing of rinse water and steam can be effectively prevented.

The operation sequence of the steam injection dishwasher system using the rinse water impeller according to an embodiment of the present invention will be described as follows.

First, water is supplied through the water supply unit, and the supplied water reaches the flow rate and temperature set in the rinse water tank 140 and the wash water tank 150.

Then, the high-temperature rinse water filled in the rinse water tank 140 is moved to the steam generator 300 through the steam water supply pump 331.

And, the rinse water moved to the steam generator 300 is generated as high-temperature steam by the steam heater 341 in the heating chamber 340.

Next, when the steam water supply pump 331 operates, the opening and closing device 350 operates to open the steam pipe 320.

Subsequently, the steam generated in the steam generator 300 moves to the water pipe 210 through the switch 350. Accordingly, steam is ejected through the rinse water spout of the rinse impeller 120 located at the top and bottom and sprayed on the dishes.

The steam ejected through the rinsing impeller 120 adheres to the contaminants attached to the dishes, thereby softening the contaminants and increasing the removal of contaminants, thereby increasing the washing efficiency of the dishes and the cleanliness of washing.

In addition, when the operation of the steam water supply pump 331 is stopped, the power applied to the steam heater 331 of the steam generator 300 is turned off, and the switch that maintains the steam pipe 320 in an open state The valve at 350 is closed and the soaking function using steam is terminated.

In addition, as the washing course progresses, washing water and rinsing water are sprayed through the washing impeller 130 and the rinsing impeller 120, respectively, and the rinsing water sprayed through the rinsing water spout and steam spout of the rinsing impeller 120 Foreign substances blocking the outlet are removed and blockage of the outlet is prevented.

Figure 4 is a flow chart illustrating the steam cleaning process of a steam injection type dishwasher using a rinse water impeller according to an embodiment of the present invention.

As shown in FIG. 4, when the steam cleaning selection key (not shown) provided on the control panel of the dishwasher is operated to select the steam injection function by the rinse water impeller (S110), the steam water pump 331 operates. It starts (S120), and the rinse water in the rinse water tank 140 is supplied into the heating chamber 340 of the steam generator 300 by pumping of the steam water pump 331 (S130).

Next, whether the steam water has reached the full water level in the heating chamber 340 is detected by the full water level sensor 342 installed in the heating chamber 340 of the steam generator 300 (S140).

As a result of the detection in step S140, if it is determined that the full water level has not been reached, the supply of steam water continues in step S130, and if it is determined that the full water level has been reached, the steam generator 300 Power is supplied to the steam heater 341 to generate steam in the heating chamber 340 (S150).

Subsequently, the steam generated in the heating chamber 340 in step S150 generates steam pressure in the heating chamber 340 after a predetermined time has elapsed, and the steam pressure generated in this way causes the opening and closing of the steam pipe 320 to open and close. The device 350 is switched to the open state (S160), and the steam generated in the heating chamber 340 passes through the steam pipe 320 and moves to the water pipe 210 through the branch pipe 310 (S170). .

Next, the steam passing through the water pipe 210 ejects steam in multiple directions through the outlet of the rinse water impeller 120 and washes the dishes arranged on the dish rack in the washing tank 110 (S180).

Next, it is determined whether the steam injection operation time set by manipulating the initial steam cleaning selection key reaches the set time set in the control unit or whether the set time has elapsed (S190).

As a result of the determination in step S190, if the set time set in the control unit is reached or the set time has elapsed, the steam cleaning function is terminated, and the steam spray operation time does not reach the set time set in the control unit or falls short of the set time. In this case, the dishwashing mode continues by returning to step S150 of generating steam, continuing to generate steam, and sequentially going through steps S160 to S190.

In this way, the present invention has the advantage of preventing clogging of the steam outlet with contaminants dropped during the dishwashing process by allowing steam to be sprayed through the rinsing impeller of the dishwasher, thereby improving steam transmission and increasing dishwashing efficiency. .

In addition, the present invention has a structure in which even if contaminants stick to or clog the steam nozzle of the rinsing impelter, they are removed by rinsing water sprayed under the water pressure of the rinsing pump operated during the washing course, thereby improving steam delivery and improving dishwashing efficiency. There is an advantage in increasing cleaning efficiency.

In addition, the present invention has the advantage of improving the cleanliness of the dishes by allowing clean steam to be sprayed onto the dishes by utilizing a rinse water pipe and rinse water that do not introduce foreign substances.

Additionally, the present invention has the advantage of improving the cleanability of the inside of the washing tank where washing water is sprayed on the dishes.

As described above, the present invention has been described with reference to the embodiments shown in the drawings, but is not limited to the embodiments and can be implemented with modifications and variations without departing from the gist of the present invention, and the modifications and variations are in accordance with the description of the present invention. included in thought.
