Description

[Technical field]

[0001] The present invention relates to a technology for cleaning a bowl of a toilet, and more particularly to a toilet bowl cleaning device and a toilet bowl cleaning method using the same, which can effectively clean the surface of the bowl of a toilet without blind areas by spraying cleaning water or disinfecting water while oscillating up and down from a cleaning nozzle controlled in a sequence operation mode to give a physical impact to the surface of the bowl of the toilet. [Background technology]

[0002] Generally, a bidet is a device that sprays cleansing water from a nozzle device onto the user's anus and / or localized area and its surroundings after defecation. A bidet is installed on a toilet and includes a bidet body that is combined with a seat cushion and a seat cover, an operating unit, and a cleaning nozzle unit that sprays cleansing water onto the user's anus and / or localized area and its surroundings.

[0003] On the other hand, the toilet bowl (or toilet seat) on which the bidet is installed is made of a ceramic structure, and even after flushing, foreign matter remains on the surface of the bowl of the toilet, creating a source of contamination that can cause limescale and the like, which can lead to the proliferation of bacteria. The proliferation of bacteria causes odors, and the odor rises during defecation, making it difficult to provide a comfortable environment for the user.

[0004] In this regard, existing Patent Publication No. 10-2017-0133053 discloses a toilet flushing device equipped with a flushing nozzle part for cleaning the bowl part, the flushing nozzle part being provided in a housing and having a jet hole, and the device includes a lifting means and a rotating means for extending and horizontally rotating the flushing nozzle part.

[0005] However, in the toilet flushing device according to the existing published patent publication, even if the flushing nozzle part is extended by the lifting means and rotated horizontally by the rotating means, the method of spraying cleaning water from the spray hole of the flushing nozzle part is direct spray, so there is a limit to how much the cleaning water sprayed from the spray hole of the flushing nozzle part can clean the surface of the bowl part of the toilet, and moreover, the existence of blind areas on the surface of the bowl part of the toilet that cannot be cleaned is unavoidable.

[0006] That is, when the nozzle portion is extended from the tip of the bidet body and then rotated in a horizontal direction to spray cleaning water from the spray hole in a direct spray manner, the cleaning water sprayed in the direct spray manner cannot physically impact the surface of the bowl portion of the toilet, and therefore cannot adequately clean contamination sources such as foreign matter and / or limescale solidified on the surface of the bowl portion of the toilet.

[0007] In addition, the flushing nozzle unit simply sprays flushing water onto the surface of the bowl of the toilet, and does not realize a sequence operation mode in which the surface of the bowl of the toilet is divided into a whole flushing area or a partial flushing area and these areas are flushed sequentially, so that the efficiency of removing the contaminants from the surface of the bowl of the toilet is inevitably reduced. Therefore, in the past, there was the inconvenience that the user had to re-wash the surface of the bowl of the toilet with a flushing brush by himself. [Prior art documents] [Patent documents]

[0040] FIG. 1 is a structural diagram of a toilet bowl cleaning device used in a bidet body according to an embodiment of the present invention, FIG. 2 is a cross-sectional schematic diagram showing a stored state of a nozzle part of a toilet bowl cleaning device according to an embodiment of the present invention, FIG. 3 is a cross-sectional schematic diagram showing an extended state of a nozzle part of a toilet bowl cleaning device according to an embodiment of the present invention, FIG. 4 is an enlarged perspective view showing the structure of the nozzle part according to an embodiment of the present invention, and FIG. 5 is an enlarged cross-sectional view showing the structure of the nozzle part according to an embodiment of the present invention.

[0041] 1 to 5, in the toilet bowl cleaning device according to the embodiment of the present invention, under the control of a bidet control unit (not shown), cleaning water flowing in at the time of start-up or disinfectant water generated by a disinfectant water generating unit (not shown) that generates disinfectant water (electrolyzed water) by electrolysis controlled by the bidet control unit is sprayed into the bowl portion 2a of the toilet 2, either heated or unheated, according to the start-up of a hot water heater (not shown), or sprayed with air supplied by an air pump, thereby removing contamination sources such as foreign matter and limescale attached to the surface of the bowl portion 2a. The toilet bowl cleaning device includes a cleaning nozzle unit 10, a nozzle head 20, and a spray guide unit 30.

[0042] Here, the cleaning water supply pipe, water supply valve, hot water heater, disinfectant water generating unit, air pump, and bidet control unit (not shown) are publicly known technologies formed inside the bidet body 1 as disclosed in Published Patent Application No. 10-2023-0045330 filed by the present inventor, and therefore detailed description thereof will be omitted below.

[0043] The cleaning nozzle portion 10 is stored on the bottom side of the bidet body 1 connected to the toilet bowl 2, as shown in FIG. 2, and may perform extension and horizontal rotation simultaneously, or may perform extension and then horizontal rotation sequentially, as shown in FIG. 3, and may include a first cylindrical portion 11, a second cylindrical portion 12, and a connecting portion 13.

[0044] Here, the storage or extension and horizontal rotation of the cleaning nozzle portion 10 is achieved by a known lifting means of a cylinder type controlled by the bidet control portion and a known rotation means driven by a transmission type, which are disclosed in the present inventor's pending patent application No. 10-2023-0039589 (filing date: 2023.03.27), and therefore detailed description thereof will be omitted below.

[0045] The first cylindrical portion 11 is an L-shaped hollow cylindrical structure for forming a water supply portion 11a connected to a cleansing water supply pipe (not shown) in the bidet body 1, and has a first internal flow path U1 through which cleansing water flows.

[0046] The second cylindrical portion 12 is a hollow cylinder structure, and serves to form a water outlet portion 12a. The second cylindrical portion 12 communicates with the first internal flow path U1 and has a second internal flow path U2 through which cleaning water flows.

[0047] Here, the water outlet portion 12a is a slot structure, which is connected to the second internal flow path U2 of the second cylindrical portion 12, functions as an installation space into which cleaning water flows, and is accommodated so that the nozzle head 20 can be inserted.

[0048] The connecting portion 13 protrudes from one end of the second cylindrical portion 12 to guide the insertion and coupling of the first cylindrical portion 11, and has a key groove 13a and a gasket groove 13b formed on its outer circumferential surface, and has a third internal passage U3 communicating with the first internal passage U1 and the second internal passage U2.

[0049] Meanwhile, an opening 11b may be formed on the outer peripheral surface of the first cylindrical portion 11, whereby a key 14 is placed in the key groove 13a through the opening 11b, and the key 14 is used to connect and fix the first cylindrical portion 11 and the connecting portion 13.

[0050] Further, the gasket groove 13b is for positioning a gasket 15 that is in close contact with the inner circumferential surface of the first cylindrical portion 11, whereby the opening 11b is a C-shaped hole structure, the key 14 may be a C-shaped ring structure positioned in the key groove 13a through the opening 11b, and the gasket 15 may be an O-ring structure or may be a closed ring that is in close contact with the inner circumferential surface of the first cylindrical portion 11.

[0051] The nozzle head 20 is inserted and coupled to the water outlet portion 12a formed in a slot structure as an installation space for the cleaning nozzle portion 10, and is configured to spray cleaning water or disinfecting water from a spray hole 21 onto the surface of the bowl portion 2a of the toilet 2. For this purpose, the nozzle head 20 is formed with a water supply hole 22 communicating with the installation space, and the spray guide portion 30 may be formed between the water supply hole 22 and the spray hole 21.

[0052] The injection guide portion 30 is formed on the nozzle head 20 and guides the discharge flow of the cleaning water or the disinfecting water in a zigzag manner so that the cleaning water or the disinfecting water is injected from the injection hole 21 while oscillating up and down.

[0053] That is, the jet guide part 30 is a ribbed block body, has a drain chamber 31 communicating with the water supply hole 22, and jets the cleaning water or the disinfecting water from the jet hole 21 while oscillating up and down. The jet guide part 30 guides the discharge flow of the cleaning water or the disinfecting water in a zigzag manner by the drain chamber 31, so that when the cleaning water or the disinfecting water is jetted from the jet hole 21, the cleaning water or the disinfecting water is jetted while oscillating up and down, and a physical impact can be applied to the surface of the bowl part 2a of the toilet 2.

[0054] As described above, in the toilet bowl cleaning device according to the embodiment of the present invention, the nozzle head 20 formed in an integrated or separate structure at the other end of the cleaning nozzle section 10 is formed with the jet guide section 30 as a ribbed block body having a drain chamber 31, and the jet guide section 30 is configured to guide the discharge flow of cleaning water or disinfecting water introduced through the water supply hole 22 of the nozzle head 20 in a zigzag pattern, so that the cleaning water or disinfecting water can be sprayed from the jet hole 21 of the nozzle head 20 onto the surface of the bowl section 2a of the toilet 2 while oscillating up and down. Therefore, the cleaning water or disinfecting water oscillating up and down gives a physical impact to the surface of the bowl section 2a of the toilet 2, and thereby contamination sources such as foreign matter and limescale attached to the surface of the bowl section 2a can be effectively removed.

[0055] Meanwhile, the toilet bowl cleaning device described with reference to Figures 1 to 5 can control the cleaning process according to a sequence operation mode by a bidet control unit provided in the bidet main body 1. This will be described in detail below with reference to Figures 1 to 16.

[0056] First, in step a, when the bidet control unit receives an input signal from a flush button (not shown) provided on the operation unit of the bidet main body 1, it opens the water supply valve in the bidet main body 1 to supply flushing water.

[0057] Next, in step b, when wash water is supplied into the bidet main body 1, the bidet control unit starts or shuts off the hot water heater in the bidet main body 1 to maintain the wash water in a hot water state within a target water temperature range of 35°C to 75°C (preferably 40°C) or in a room temperature water state.

[0058] Furthermore, in step c, when the unheated room temperature water or the cleaning water heated by the hot water heater reaches a target water temperature, the bidet control unit judges whether disinfectant water has been introduced into the cleaning nozzle unit 10 stored on the bottom side of the bidet body 1 or whether air has been mixed in, and controls a plurality of sequence operation modes for changing the extension distance and horizontal rotation angle of the cleaning nozzle unit 10, thereby spraying the cleaning water or disinfectant water onto the surface of the bowl unit 2a while oscillating up and down, thereby applying a physical impact to the surface of the bowl unit 2a of the toilet 2 and cleaning or disinfecting it.

[0059] That is, as shown in FIG. 6, the sequence operation modes controlled by the bidet control unit are executed in the following order: soaking mode S10 → cleaning mode S20 → deep cleaning mode S30 → flushing mode S40 → disinfection mode S50, and each operation mode will be described in detail below.

[0060] As shown in FIG. 7, the soaking mode S10 is a mode for soaking contamination sources attached to the surface of the bowl portion 2a of the toilet 2, and may include first to third steps.

[0061] As shown in FIG. 3, in the first step, after the step b, the lifting means is driven and controlled to cause the washing nozzle portion 10 housed on the bottom side of the bidet body 1 to extend downward.

[0062] Here, the maximum extension distance of the cleaning nozzle portion 10 by the lifting means may be 180 mm or less.

[0063] Next, as shown in FIG. 12, in the second step, the rotation means is driven and controlled to horizontally rotate the extended cleaning nozzle portion 10 back and forth from an initial rotation angle (e.g., 0°) to a maximum rotation angle (e.g., 360°).

[0064] In this case, the cleaning nozzle section 10 may be extended and rotated horizontally at the same time, or may be extended and then rotated horizontally. When the cleaning nozzle section 10 rotates horizontally, cleaning water flowing in through the water supply section 11a of the first cylindrical section 11 constituting the cleaning nozzle section 10 can be discharged from the water outlet section 12a through the first internal flow path U1, the third internal flow path U3 of the connecting section 13, and the second internal flow path U2 of the second cylindrical section 12.

[0065] The cleaning water discharged as described above flows into drain chamber 31 of spray guide section 30 formed within nozzle head 20 via water supply hole 22 of nozzle head 20 formed in water outlet section 12a, and the discharge flow of the cleaning water is further guided in a zigzag manner, whereby cleaning water heated to a temperature within the range of 35°C to 75°C (preferably 40°C) is repeatedly sprayed from spray hole 21 of nozzle head 20 onto the surface of bowl section 2a of toilet 2 while oscillating up and down, so that the contamination source on the surface of bowl section 2a is initially immersed.

[0066] Here, the heating temperature of the washing water is limited to within the range of 35°C to 75°C, but this range can also be subdivided into the range of 35°C to 45°C or 65°C to 75°C.

[0067] Thereafter, in a third step, the heated cleaning water is repeatedly sprayed onto the surface of the bowl portion 2a while swinging up and down due to the reciprocating horizontal rotation of the cleaning nozzle portion 10, thereby immersing the contamination source, and then, in order to execute the next operating mode, i.e., the cleaning mode S20, the horizontal rotation of the cleaning nozzle portion 10 is stopped and the cleaning nozzle portion 10 is returned to its initial rotation angle to end the immersion mode S10.

[0068] As shown in FIG. 8, the cleaning mode S20 is a mode for first removing contamination sources on the surface of the bowl portion 2a of the toilet 2 immersed in the immersion mode S10 by brushing, and may include a fourth step and a fifth step.

[0069] As shown in FIG. 13, in the fourth step, the extended cleaning nozzle portion 10 is caused to repeatedly rotate horizontally at a first rotation angle (e.g., angle N) and at a second rotation angle (e.g., angle N1) smaller than the first rotation angle (N>N1), and the discharge flow is guided in a zigzag manner by the drainage chamber 31 of the injection guide portion 30 formed in the nozzle head 20, so that warm cleaning water heated to a range of 35°C to 75°C (preferably 40°C) is repeatedly sprayed from the injection hole 21 of the nozzle head 20 onto a part of the divided area on the surface of the bowl portion 2a while oscillating up and down, thereby repeatedly cleaning the surface of the bowl portion 2a.

[0070] Then, in the fifth step, when the cleaning nozzle unit, which repeatedly sprays heated cleaning water while oscillating up and down, reaches the maximum rotation angle through repeated horizontal rotation from the first rotation angle to the second rotation angle, the horizontal rotation of the cleaning nozzle unit 10 is stopped and the cleaning nozzle unit 10 is returned to the initial rotation angle to end the cleaning mode S20.

[0071] As shown in FIG. 9, the deep cleaning mode S30 is a mode for removing contamination sources on the surface of the bowl portion 2a of the toilet 2 twice by brushing after the cleaning mode S20, and may include steps 6 to 9.

[0072] As shown in FIG. 14, in the sixth step, the cleaning nozzle unit 10 housed in the bottom side of the bidet body 1 is horizontally rotated by reciprocating within a first rotation angle (e.g., angle N), and the discharge flow is guided in a zigzag manner by the drainage chamber 31 of the spray guide unit 30 formed in the nozzle head 20, so that the warm cleaning water heated to a range of 35°C to 75°C (preferably 40°C) is repeatedly sprayed onto the upper and lower surfaces of the bowl unit 2a from the spray hole 21 of the nozzle head 20 while oscillating up and down.

[0073] Next, in a seventh step, the horizontal rotation of the cleaning nozzle unit 10 is stopped, and the cleaning nozzle unit 10 is returned to the initial rotation angle.

[0074] As shown in FIG. 14, in the eighth step, the cleaning nozzle portion 10 is rotated horizontally by reciprocating within a second rotation angle range (e.g., angle N1), and the discharge flow is guided in a zigzag manner by the drainage chamber 31 of the injection guide portion 30 formed in the nozzle head 20, so that warm cleaning water heated to a range of 35°C to 75°C (preferably 40°C) is repeatedly sprayed onto the left and right surfaces of the bowl portion 2a from the injection hole 21 of the nozzle head 20 while oscillating up and down.

[0075] In the ninth step, the horizontal rotation of the cleaning nozzle unit 10 is stopped and the cleaning nozzle unit 10 is returned to the initial rotation angle. In this case, the bidet control unit repeats the sixth to ninth steps a predetermined number of times, thereby removing all sources of contamination on the surface of the bowl unit 2a of the toilet 2.

[0076] As shown in FIG. 10, the flushing mode S40 is a mode for removing contamination sources remaining on the surface of the bowl portion 2a of the toilet 2 from which the contamination sources have been removed by the deep flushing mode S30, and may include a tenth step and an eleventh step.

[0077] In the tenth step, based on step b, the hot water heater is kept on or off to heat the cleaning water to hot water in the range of 35°C to 75°C (preferably 40°C) or to be maintained as unheated room temperature water.

[0078] As shown in FIG. 15, in the 11th step, the cleaning nozzle portion 10 is rotated horizontally at the maximum rotation angle, and the discharge flow is guided in a zigzag manner by the first drainage chamber 31 and the second drainage chamber 32 of the spray guide portion 30 formed in the nozzle head 20, so that warm cleaning water heated to a range of 35°C to 75°C (preferably 40°C) or unheated room temperature water is repeatedly sprayed onto the surface of the bowl portion 2a from the spray hole 21 of the nozzle head 20 while oscillating up and down, thereby removing sources of contamination remaining on the surface of the bowl portion 2a of the toilet 2.

[0079] As shown in FIG. 11, the disinfection mode S50 is a mode for disinfecting the surface of the bowl portion 2a of the toilet 2 from which residual contamination sources have been removed by the flushing mode S40, and may include steps 12 to 14.

[0080] In the 12th step, while maintaining the activation or shutoff of the hot water heater, the disinfectant water generating unit provided in the bidet body 1 is activated to generate disinfectant water (or electrolytic water), and the disinfectant water is heated to a temperature within a range of 35°C to 75°C (preferably 40°C) or is maintained at room temperature without heating.

[0081] As shown in FIG. 16, in the subsequent 13th step, the cleaning nozzle portion 10 having reached the maximum extension distance is rotated horizontally, and the discharge flow is guided in a zigzag manner by the drainage chamber 31 of the injection guide portion 30 formed in the nozzle head 20, so that disinfectant water heated to a temperature within a range of 35°C to 75°C (preferably 40°C) or unheated disinfectant water is repeatedly sprayed onto the surface of the bowl portion 2a from the injection hole 21 of the nozzle head 20 while oscillating up and down, thereby cleaning the bowl portion 2a of the toilet 2.

[0082] In the subsequent 14th step, if the hot water heater is started, the hot water heater and the disinfectant water generating unit are shut off, the water supply valve opened in step a is closed, the cleaning nozzle unit 10 is stored in the bottom surface of the bidet main body 1, and the sequence operation mode by the bidet control unit is terminated.

[0083] On the other hand, the bidet control unit controls the sequence of operation modes from the soaking mode S10 to the cleaning mode S20 to the deep cleaning mode S30 to the flushing mode S40 to the disinfection mode S50. When cleaning the contamination source from the bowl part 2a of the toilet 2 with cleaning water or disinfection water, air may be mixed into the cleaning water or disinfection water through the air pump in each of the sequence operation modes. In this case, the amount of air mixed in is controlled to be a first mixed amount in the soaking mode S10, the flushing mode S40, and the disinfection mode S50, and the amount of air mixed in is controlled to be a second mixed amount larger than the first mixed amount in the cleaning mode S20 and the deep cleaning S30 mode, thereby improving the spray efficiency of spraying the cleaning water or the disinfection water from the spray hole 21 of the nozzle head 20 while oscillating up and down.

[0084] On the other hand, as the sequence operation modes described above, in the immersion mode S10, the cleaning mode S20, the deep cleaning mode S30, the flushing mode S40, and the disinfection mode S50, the cleaning nozzle unit 10 is in an extended state and is rotated horizontally to spray cleaning water or disinfecting water while oscillating up and down. However, the present invention is not limited to such literature explanations, and also includes a case where the cleaning nozzle unit 10 is rotated horizontally at a first rotation angle, a second rotation angle, and a maximum rotation angle of 360° based on an initial rotation angle of 0° during the process of moving the cleaning nozzle unit 10 up and down within a range of 180 mm, which is the maximum extension distance, to spray cleaning water or disinfecting water onto the surface of the bowl unit 2a of the toilet 2 while oscillating up and down, which is for the purpose of reducing the cleaning blind area on the surface of the bowl unit 2a as much as possible.

[0085] The technical concepts of the toilet bowl cleaning device and toilet bowl cleaning method using the same according to the present invention have been described in detail above with reference to the drawings. However, this is merely an illustrative description of the best embodiment of the present invention and is not intended to limit the present invention.

[0086] It is therefore understood that the present invention is not limited to the specific preferred embodiments described above, but rather that various modifications may be made by those skilled in the art without departing from the spirit of the invention sought to be protected by the appended claims, and that such modifications are also intended to be included within the scope of the appended claims.
