Description

Technology Field

[0001] The present invention relates to a dishwasher combined with a sink, and more specifically, to a dishwasher combined with a sink that enables effective washing of dishes according to the source of contamination by sequentially supplying an eco-friendly detergent having a basic or acidic nature to a sink into which used dishes are placed. Background Technology

[0003] In general, dishwashers widely used in restaurants or homes install washing nozzles and rinsing nozzles at two locations, the floor and the ceiling of the washing chamber of the dishwasher, and wash dishes by pumping washing water and rinsing water with a washing motor and spraying them through the washing nozzles and rinsing nozzles.

[0004] Since the aforementioned dishwasher is installed around the kitchen sink, it requires separate installation space, making it difficult to utilize kitchen space efficiently. Consequently, it has the disadvantage of being very difficult to install in narrow kitchens. Additionally, because the dishwasher is manufactured separately from the sink, there is a problem of increased manufacturing costs.

[0005] Recently, to solve the above-mentioned problems, technology has been developed that integrates the sink and dishwasher into a single unit. As an example, to briefly explain Public Utility Model No. 20-1995-011111 (sink with attached dishwasher), a body is installed in a partitioned section of the sink, a lid plate is installed at the rear of the body to be opened and closed by a hinge, and rotary fountains having spray nozzle holes are installed on the upper and lower sides inside the body.

[0006] In addition, Registered Patent No. 10-1570844 (Sink-integrated dishwasher) is disclosed. The above technology washes dishes by spraying hot and cold water through a spray nozzle along with the generation of steam.

[0007] Meanwhile, neutral detergents usually have a neutral pH of 7, so they have the advantage of minimizing skin irritation and allowing for safe dishwashing.

[0008] However, the disadvantage of neutral detergent is that it has a neutral pH of 7, which limits its ability to clean heavily soiled dishes.

[0009] It is true that modern food is high in protein and fat, so even when washing dishes with a neutral detergent, the dishes remain slippery, and the sense of efficacy or satisfaction regarding the cleanliness of the dishes is reduced.

[0010] For this reason, among young people, a method of washing dishes using citric acid, sodium carbonate, and sodium percarbonate, which are highly effective and eco-friendly, is widely used.

[0011] However, while eco-friendly detergents have excellent cleaning effects, they may pose health risks, such as generating gas when used indoors or causing skin irritation upon direct contact, so caution is required when using them. Prior art literature

[0037] Hereinafter, a preferred embodiment of a dishwasher combined with a sink according to the present invention will be described in detail with reference to the attached drawings.

[0039] FIG. 1 is a conceptual cross-sectional view of a dishwasher combined with a sink according to the present invention, FIG. 2 is a control block diagram of a dishwasher combined with a sink according to the present invention, and FIG. 3 (a) and (b) are drawings illustrating a first detergent container and a second detergent container of a dishwasher combined with a sink according to the present invention.

[0041] The present invention relates to a dishwasher (50, hereinafter referred to as "dishwasher") that can effectively wash dishes according to the source of contamination by sequentially supplying an eco-friendly detergent having a basic or acidic nature to a sink into which used dishes are placed. As shown in FIGS. 1 to 3, the configuration may include a sink (100) provided with a nozzle (110) for spraying washing water or washing liquid and a drain (120) for draining washing water or washing liquid, a cover member (200) for covering the open top of the sink (100), a detergent container (300) for storing detergent, a washing liquid supply unit (400) for supplying a washing liquid mixed with washing water supplied from a water supply unit (10) and detergent to the nozzle (110), and a gas discharge unit (500) for discharging gas generated from the washing liquid.

[0042] To explain in more detail, the sink (100) is formed in a box shape with an open top so as to accommodate dishes inside, and can be used as a general sink. Therefore, the dishwasher (50) of the present invention can be used as a sink and then as a dishwasher, making it easy to install even without a separate space to install a dishwasher.

[0043] Of course, the dishwasher (50) of the present invention may be installed on one sink (100) of a sink with two sinks, and the other sink may be used for various purposes such as preparing food ingredients.

[0044] At this time, a rack (101) for storing tableware may be provided inside the sink (100), and the rack (101) may be installed in one or multiple layers inside the sink (100).

[0045] In addition, the drain (120) is configured to be automatically opened and closed according to the cleaning stage.

[0046] Then, the washing water supplied from the above-mentioned water supply unit (10) or the washing liquid supplied from the washing liquid supply unit (400) to be described later is sprayed into the sink (100) through the nozzle (110).

[0047] Of course, the sink (100) is provided with a pipe on its inner wall for the washing water or washing liquid to move to the nozzle (110).

[0048] Meanwhile, the sink (100) may be equipped with a stirring device (130) for stirring the washing water or washing liquid contained therein to generate a water current.

[0049] The above stirring device (130) includes a stirring blade operated by a stirring motor, and when the stirring device (130) is operated, the washing water or washing liquid contained inside the sink (100) is stirred by the stirring blade, thereby washing the dishes.

[0050] In addition, the open upper portion of the sink (100) can be kept closed by a cover member (200) during the operation of the dishwasher (50) to prevent washing water or washing liquid from leaking out of the sink (100).

[0051] In addition, the cover member (200) is provided with a pipe that communicates with the pipe of the sink (100) so that washing water or washing liquid can move, and is equipped with a cover nozzle (210) so that washing water or washing liquid can be sprayed from the upper side of the sink (100) to increase the cleaning power.

[0052] Meanwhile, the dishwasher (50) of the present invention may further include a heating unit (600) for heating the washing water before mixing the washing water and detergent.

[0053] Therefore, washing water is supplied from the water supply valve (12) of the above-mentioned water supply unit (10) to the heating unit (600), and the washing water is heated and supplied to the nozzle (110) so that the detergent dissolves well in the washing water and mixes well, thereby allowing the generation of the washing solution to be carried out more smoothly.

[0054] In addition, it is desirable that the sink (100) be provided with an insulating material (150) on its outer surface so as to maintain the temperature of the washing water or washing liquid contained inside the sink (100) and to prevent noise.

[0056] Meanwhile, the detergent container (300) may include a first detergent container (310) in which a first detergent is stored and a second detergent container (320) in which a second detergent is stored.

[0057] At this time, the first detergent may be an eco-friendly alkaline detergent such as sodium bicarbonate (baking soda), sodium carbonate (washing soda), or sodium percarbonate, and the second detergent may be an eco-friendly acidic detergent such as citric acid.

[0058] Additionally, the washing liquid supply unit (400) may include a first washing liquid supply unit (410) that supplies a first washing liquid mixed with a first detergent and washing water to the nozzle (110), and a second washing liquid supply unit (420) that supplies a second washing liquid mixed with a second detergent and washing water to the nozzle (110).

[0059] Therefore, the washing water can be supplied directly to the nozzle (110) or supplied to the first washing liquid supply unit (410) or the second washing liquid supply unit (420) by means of a distribution valve (14) that controls the supply of the washing water heated in the above-mentioned water supply unit (10) or heating unit (600).

[0060] Then, the first detergent discharge valve (312) of the first detergent container (310) and the second detergent discharge valve (322) of the second detergent container (320) are opened to supply detergent to the first washing liquid supply unit (410) and the second washing liquid supply unit (420), and as the detergent and washing water are mixed, a washing liquid having an alkaline or acidic nature is produced.

[0061] At this time, the first detergent container (310) and the second detergent container (320) may be configured such that the outlet (30) through which the detergent is discharged is kept sealed by a sealing film (32) made of vinyl or metal and a lid (34), as shown in FIG. 3 (a).

[0062] Therefore, the first detergent container (310) and the second detergent container (320) are double-sealed by the sealing membrane (32) and the lid (34) under normal circumstances, and even when the lid (34) is opened, they remain sealed by the sealing membrane (32), thereby preventing strong alkaline and strong acidic detergents from coming into contact with the user's skin or respiratory system, thus having the effect of preventing safety accidents.

[0063] Here, when the lid (34) is opened and connected to the connection part between the first detergent discharge valve (312) and the second detergent discharge valve (322), the sealing membrane (32) is torn, thereby allowing opening. Each connection part between the first detergent container (310) and the second detergent container (320) and the first detergent discharge valve (312) and the second detergent discharge valve (322) is equipped with a cutter blade (C) that tears the sealing membrane (32). By simply combining each component, the sealing membrane (32) is torn, and the discharge port (30) of the first detergent container (310) and the second detergent container (320) is opened so that the detergent can be discharged.

[0064] At this time, the alkaline and acidic cleaning solutions can be supplied sequentially to the sink (100), and first, the alkaline cleaning solution is supplied to the sink (100) to remove foreign substances such as oil on the dishes.

[0065] Next, after rinsing with washing water, an acidic washing solution is supplied to the sink (100) to remove water stains or burnt-on foreign matter from the dishes, and a neutralization reaction is performed with the alkaline washing solution that may remain on the dishes to minimize the residue of the washing solution.

[0066] Next, the dishes are rinsed a second time with wash water to complete the washing process.

[0067] Meanwhile, a pH concentration sensing sensor (140) may be further provided inside the sink (100), and the pH concentration sensing sensor (140) is configured to detect the pH concentration of the washing water or washing liquid contained in the sink (100).

[0068] Therefore, depending on the pH concentration of the washing water or washing liquid measured by the pH concentration detection sensor (140), the first detergent discharge valve (312) of the first detergent container (310) or the second detergent discharge valve (322) of the second detergent container (320) is opened, and an acidic or alkaline washing liquid is supplied into the sink (100) from the first washing liquid supply unit (410) or the second washing liquid supply unit (420), thereby allowing the amount of detergent to be adjusted and the amount of detergent to be appropriate for the source of contamination and the degree of contamination to be neutralized.

[0069] In this process, gas such as carbon dioxide may be generated by the cleaning solution while the dishwasher (50) is operating, and the gas is discharged through the gas discharge unit (500) to prevent it from entering the room.

[0070] The above drain (120) is connected to a drain pipe (122), and the above sink (100) is provided with an auxiliary drain pipe (124) connected to the drain pipe (122) to prevent water overflow on the side.

[0071] At this time, the gas discharge unit (500) is embedded in the auxiliary drain pipe (124), and the end where the gas is discharged may be located at the rear end of the odor backflow prevention unit (123) of the drain pipe (122). That is, referring to FIG. 1, the front end of the gas discharge unit (500) is located at the sink (100) side inlet of the auxiliary drain pipe (124), and the rear end is located at the rear after passing through the water accumulated in the odor backflow prevention unit (123) of the drain pipe (122).

[0072] The odor backflow prevention part (123) of the above drain pipe (122) is formed in a U-shape so that water always remains, thereby preventing backflow of odor or entry of insects due to the accumulated water, and is a known configuration.

[0073] Therefore, by discharging gas to the rear of the water accumulated in the odor backflow prevention unit (123) through the gas discharge unit (500), the backflow of the discharged gas by the water accumulated in the odor backflow prevention unit (123) can be prevented.

[0074] In addition, the gas discharge unit (500) may be equipped with a suction pump (510) for sucking in gas.

[0075] Therefore, by operating the suction pump (510), the gas inside the sink (100) is sucked in to the front end of the gas discharge section (500) and discharged to the rear end of the gas discharge section (500).

[0076] Additionally, the gas discharge unit (500) may be equipped with a backflow prevention valve (520), and backflow of gas and odor through the gas discharge unit (500) can be prevented by the backflow prevention valve (520).

[0077] Meanwhile, in the present invention, the operation of the above-mentioned water supply valve (12), distribution valve (14), drain (120), stirring device (130), first detergent discharge valve (312), second detergent discharge valve (322), suction pump (510), and heating unit (600) can all be controlled by the control unit (700), and the control panel (not shown) equipped with the control unit (700) may be provided on the cover member (200) or provided separately.

[0079] Accordingly, the dishwasher (50) combined with a sink according to the present invention as described above has various advantages, such as being able to effectively wash dishes according to the source of contamination by sequentially supplying an eco-friendly detergent having a basic or acidic nature to the sink into which used dishes are placed, preventing gases such as carbon dioxide generated when using the eco-friendly detergent from entering the indoors, and allowing for safer use by discharging them through a drain pipe.

[0081] The above-described embodiments are explained with respect to the most preferred examples of the present invention, but are not limited to the above embodiments, and it is obvious to those skilled in the art that various modifications are possible within the scope of the technical spirit of the present invention.
