Description

Technical Field

[0001] The present invention relates to a technology for cleaning a toilet bowl, and more particularly, to a toilet bowl cleaning device and a toilet bowl cleaning method using the same, which sprays cleaning water or disinfecting water in an up and down swinging manner by implementing a cleaning nozzle portion controlled by a sequence working mode so as to apply a physical impact to the surface of the toilet bowl, thereby effectively cleaning the surface of the toilet bowl without a blind spot. Background Art

[0002] Generally, a bidet refers to a device that sprays cleaning water onto the user's anus and / or local area and its surroundings through a nozzle device after defecation. It is set on the toilet and includes a bidet body combined with a seat cushion and a seat cover, an operating part, and a cleaning nozzle part that sprays cleaning water onto the user's anus and / or local area and its surroundings.

[0003] On the other hand, the toilet (or toilet bowl) equipped with the bidet is a ceramic structure. After flushing, foreign matter still remains on the surface of the toilet bowl, so there may be pollution sources such as scale, and it will cause bacteria to multiply. The bacterial growth causes a bad taste and a bad odor during defecation, which cannot provide a comfortable environment for users.

[0004] In this regard, in the past, as disclosed in Patent Gazette No. 10-2017-0133053, a toilet cleaning device is disclosed, which includes a bowl cleaning nozzle portion provided in a housing and having a spray hole, and includes a lifting unit and a rotating unit for extending and horizontally rotating the cleaning nozzle portion.

[0005] However, even if the toilet cleaning device of the prior art patent extends the cleaning nozzle portion by the lifting unit and rotates it horizontally by the rotating unit, since the cleaning water is sprayed through the spray hole of the cleaning nozzle portion in a direct manner, there are limitations in cleaning the surface of the toilet bowl using the cleaning water sprayed from the spray hole of the cleaning nozzle portion, and a blind area that cannot be cleaned is inevitably generated on the surface of the toilet bowl.

[0006] That is, after the nozzle portion extends from the front end of the bidet body, it rotates in the horizontal direction and sprays cleaning water in a direct manner through the spray hole. The cleaning water in a direct manner cannot exert a physical impact on the surface of the toilet bowl, and therefore cannot satisfactorily clean foreign matter and / or scale and other pollution sources solidified on the surface of the toilet bowl.

[0007] Moreover, the cleaning nozzle portion simply sprays cleaning water onto the surface of the toilet bowl, and does not implement a sequential working mode of dividing the surface of the toilet bowl into an overall cleaning area or a partial cleaning area and performing cleaning in sequence. This inevitably leads to a decrease in the efficiency of removing pollution sources on the surface of the toilet bowl. Therefore, in the past, there was the inconvenience of users having to use a cleaning brush to personally re-clean the surface of the toilet bowl.

[0061] Reference Figures 1 to 5 In the toilet bowl cleaning device of an embodiment of the present invention, an unillustrated water supply valve arranged on an unillustrated cleaning water supply pipeline connected to the bidet body 1 is controlled by an unillustrated bidet control unit to heat the cleaning water flowing in at startup or the disinfectant water (electrolyzed water) generated by the disinfectant water generating unit controlled by the bidet control unit according to the startup of the unillustrated hot water heater or spray the unheated normal temperature cleaning water or disinfectant water onto the bowl 2a of the toilet 2 or spray it mixed with air supplied by an air pump to remove foreign matter or scale and other pollution sources attached to the surface of the bowl 2a. The toilet bowl cleaning device includes a cleaning nozzle unit 10, a nozzle head 20 and a spray guide unit 30.

[0062] Among them, the cleaning water supply pipeline, water supply valve, hot water heater, disinfectant water generating unit, air pump, and bidet control unit not shown in the figure are known technologies formed inside the bidet body 1 disclosed in the published patent gazette No. 10-2023-0045330 applied by the inventor, and therefore, their detailed description will be omitted below.

[0063] like Figure 2 As shown, the cleaning nozzle 10 is housed on one side of the bottom surface of the bidet body 1 combined with the toilet 2, as shown in FIG. Figure 3 As shown, the elongation movement and the horizontal rotation can be realized simultaneously, or the horizontal rotation can be realized in sequence after the elongation movement, and may include a first cylindrical portion 11, a second cylindrical portion 12, and a connecting portion 13.

[0064] Among them, the storage or extension movement and horizontal rotation of the cleaning nozzle part 10 are realized by the known lifting unit with a cylinder method controlled by the bidet control part and the known rotating unit driven by a transmission method disclosed in the patent application No. 10-2023-0039589 (application date: 2023.03.27.) currently applied by the inventor, so its detailed description will be omitted below.

[0065] The first cylindrical portion 11 is an L-shaped hollow cylindrical structure for forming a water inlet 11a connected to a cleaning water supply pipeline (not shown) in the bidet body 1 and having a first internal flow path U1 for the cleaning water to flow.

[0066] The second cylindrical portion 12 is a hollow cylinder structure, and is used to form a water outlet 12a, which is connected to the first internal flow path U1 and has a second internal flow path U2 for the flow of cleaning water.

[0067] The water outlet 12a is a slot structure, which is connected to the second internal flow path U2 of the second cylindrical portion 12, and is used as an installation space for the cleaning water to flow in, and is used for placing the nozzle head 20 in an inserted manner.

[0068] The connecting portion 13 protrudes at one end of the second cylindrical portion 12 and is used to guide the insertion and connection of the first cylindrical portion 11. A key groove 13a and a sealing gasket groove 13b are formed on the outer peripheral surface, and the connecting portion 13 has a third internal flow path U3 connected to the first internal flow path U1 and the second internal flow path U2.

[0069] On the other hand, an open opening 11 b may be formed on the outer circumferential surface of the first cylindrical portion 11 , so that a key 14 is placed in the key groove 13 a through the open opening 11 b , and the key 14 is used for connecting and fixing the first cylindrical portion 11 and the connecting portion 13 .

[0070] Moreover, the sealing gasket groove 13b can be used to place a sealing gasket 15 that is tightly attached to the inner circumference of the first cylindrical portion 11. Thus, the open port 11b is a C-shaped hole structure, the key 14 can be a C-shaped ring structure, which is placed in the key groove 13a through the open port 11b, and the sealing gasket 15 can be an O-ring structure, which is a closed loop that is tightly attached to the inner circumference of the first cylindrical portion 11.

[0071] The nozzle head 20 is inserted into and combined with the water outlet portion 12a side of the slot structure constituting the installation space of the cleaning nozzle portion 10, and sprays cleaning water or disinfecting water onto the surface of the bowl portion 2a of the toilet 2 through the spray hole 21. Therefore, not only can the nozzle head 20 be provided with a water inlet hole 22 connected to the installation space, but also the spray guide portion 30 can be formed between the water inlet hole 22 and the spray hole 21.

[0072] The spray guide 30 is formed at the nozzle head 20 to guide the discharge flow of the cleaning water or the disinfecting water in a zigzag manner so as to spray the cleaning water or the disinfecting water through the spray hole 21 in an up-and-down swing manner.

[0073] That is, the injection guide portion 30 is a rib-shaped block, having a drainage chamber 31 connected to the water inlet hole 22, so that the cleaning water or the disinfecting water can be injected through the injection hole 21 in an up and down swinging manner. The injection guide portion 30 guides the discharge flow of the cleaning water or the disinfecting water in a zigzag manner through the drainage chamber 31. Therefore, when the cleaning water or the disinfecting water is injected through the injection hole 21, the cleaning water or the disinfecting water can be injected in an up and down swinging manner, thereby being able to apply a physical impact to the surface of the bowl 2a of the toilet 2.

[0074] As described above, the toilet bowl cleaning device of an embodiment of the present invention has a nozzle head 20 formed at the other end of the cleaning nozzle part 10 in an integrated structure or a separated structure, which is configured to have a spray guide portion 30 as a rib-shaped block with a drainage chamber 31. The spray guide portion 30 guides the discharge flow of the cleaning water or disinfecting water introduced through the water inlet hole 22 of the nozzle head 20 in a zigzag manner. As a result, the spray hole 21 of the nozzle head 20 can spray the cleaning water or disinfecting water onto the surface of the bowl 2a of the toilet 2 in an up and down swinging manner. Therefore, as the up and down swinging cleaning water or disinfecting water applies physical impact to the surface of the bowl 2a of the toilet 2, foreign matter or scale and other pollution sources attached to the surface of the bowl 2a can be effectively removed.

[0075] On the other hand, refer to Figures 1 to 5 The toilet bowl cleaning device described above can be controlled by the bidet control unit arranged in the bidet body 1 according to the sequence working mode. Figures 1 to 16 Detailed description.

[0076] First, in step a, when the bidet control unit receives an input signal from a cleaning button (not shown) disposed on the operation unit of the bidet body 1, the bidet control unit controls the water supply valve in the bidet body 1 to open, thereby supplying cleaning water.

[0077] Next, in step b, when washing water is supplied to the bidet body 1, the bidet control unit starts or shuts down the hot water heater in the bidet body 1 to keep the washing water in a hot water state or a normal temperature state at a target water temperature within the range of 35°C to 75°C (preferably 40°C).

[0078] Subsequently, in step c, when the unheated room temperature water or the cleaning water heated by the hot water heater reaches the target water temperature, the bidet control unit controls a plurality of sequence operating modes for determining whether disinfecting water is introduced into the cleaning nozzle unit 10 housed on one side of the bottom surface of the bidet body 1, whether air is mixed, and for changing the extension moving distance and horizontal rotation angle of the cleaning nozzle unit 10, and achieves cleaning or disinfection by spraying cleaning water or disinfecting water onto the surface of the bowl 2a in an up and down swinging manner, thereby applying physical impact to the surface of the bowl 2a of the toilet 2.

[0079] That is, Figure 6 As shown, the sequential working modes controlled by the bidet control unit are executed in the order of soaking mode S10 →cleaning mode S20 →deep cleaning mode S30 →rinsing mode S40 →disinfection mode S50. Each working mode is described in detail below.

[0080] like Figure 7 As shown, the soaking mode S10 is a mode for soaking the pollution source attached to the surface of the bowl 2a of the toilet 2, and may include the first step to the third step.

[0081] like Figure 3 As shown, in the first step, after the step b, the driving of the lifting unit is controlled so that the cleaning nozzle part 10 stored on one side of the bottom surface of the bidet body 1 is extended and moved downward.

[0082] The maximum extension movement distance of the cleaning nozzle part 10 achieved by the lifting unit may be within 180 mm.

[0083] Then, if Fig.12 As shown, in the second step, by driving and controlling the rotating unit, the extended and moved cleaning nozzle portion 10 reciprocates from an initial rotation angle (eg, 0°) to a maximum rotation angle (eg, 360°) to perform horizontal rotation.

[0084] At this time, the extension movement and horizontal rotation of the cleaning nozzle part 10 can be achieved simultaneously, or the extension movement can be achieved followed by horizontal rotation. When the cleaning nozzle part 10 rotates horizontally, the cleaning water flowing in through the water inlet part 11a of the first cylindrical part 11 constituting the cleaning nozzle part 10 can be discharged from the water outlet part 12a via the first internal flow path U1, the third internal flow path U3 of the connecting part 13 and the second internal flow path U2 of the second cylindrical part 12.

[0085] Moreover, as the cleaning water discharged in the above manner flows into the drainage chamber 31 of the injection guide portion 30 in the nozzle head 20 through the water inlet hole 22 of the nozzle head 20 formed in the water outlet portion 12a, the discharge flow of the cleaning water is guided in a zigzag manner, thereby, the injection hole 21 of the nozzle head 20 repeatedly sprays the cleaning water heated to a temperature in the range of 35°C to 75°C (preferably 40°C) toward the surface of the bowl 2a of the toilet 2 in an up and down swinging manner, thereby first soaking the pollution source on the surface of the bowl 2a.

[0086] Here, it is described that the heating temperature of the washing water is in the range of 35°C to 75°C, but the heating temperature may be further divided into the range of 35°C to 45°C or the range of 65°C to 75°C.

[0087] Subsequently, in the third step, the cleaning nozzle part 10 is reciprocated horizontally to repeatedly spray heated cleaning water onto the surface of the basin part 2a in an up and down swinging manner to soak the pollution source. Then, in order to execute the next working mode, namely the cleaning mode S20, the horizontal rotation of the cleaning nozzle part 10 is stopped, and the cleaning nozzle part 10 is returned to the initial rotation angle, thereby ending the soaking mode S10.

[0088] like Figure 8 As shown, the cleaning mode S20 is a mode for initially removing the pollution sources soaked on the surface of the bowl 2a of the toilet 2 after the soaking mode S10 by brushing, and may include a fourth step and a fifth step.

[0089] like Fig.13 As shown, in the fourth step, the extended cleaning nozzle portion 10 is repeatedly rotated horizontally at a first rotation angle (for example, angle N) and a second rotation angle (for example, angle N1) smaller than the first rotation angle (N>N1), and the discharge flow is guided in a zigzag manner through the drainage chamber 31 of the injection guide portion 30 formed in the nozzle head 20. Therefore, the surface of the basin portion 2a is repeatedly cleaned by repeatedly spraying cleaning water heated to hot water in the range of 35°C to 75°C (preferably 40°C) to the partially divided area on the surface of the basin portion 2a through the injection hole 21 of the nozzle head 20 in an up and down swinging manner.

[0090] Then, in the fifth step, at the time point when the cleaning nozzle unit that repeatedly sprays heated cleaning water in an up and down swinging manner 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, thereby ending the cleaning mode S20.

[0091] like Fig. 9 As shown, the deep cleaning mode S30 is a mode for secondary removal of pollution sources on the surface of the bowl 2a of the toilet 2 after the cleaning mode S20 by brushing, and may include the sixth step to the ninth step.

[0092] like Fig.14 As shown, in the sixth step, the cleaning nozzle portion 10 housed on one side of the bottom surface of the bidet body 1 is reciprocated within a first rotation angle (for example, angle N) to perform horizontal rotation, and the drainage chamber 31 of the injection guide portion 30 formed in the nozzle head 20 guides the discharge flow in a zigzag manner, so that the injection hole 21 of the nozzle head 20 repeatedly injects cleaning water heated to a temperature in the range of 35°C to 75°C (preferably 40°C) toward the upper and lower surfaces of the basin portion 2a in an up and down swinging manner.

[0093] Next, in the seventh step, after the horizontal rotation of the cleaning nozzle unit 10 is stopped, the cleaning nozzle unit 10 is returned to the initial rotation angle.

[0094] like Fig.14 As shown, in the subsequent eighth step, the cleaning nozzle portion 10 is reciprocated within a second rotation angle range (for example, angle N1) to perform horizontal rotation, and the drainage chamber 31 of the injection guide portion 30 formed in the nozzle head 20 guides the discharge flow in a zigzag manner, so that the injection hole 21 of the nozzle head 20 repeatedly sprays the cleaning water heated to the range of 35°C to 75°C (preferably 40°C) to the left and right surfaces of the basin portion 2a in an up and down swinging manner.

[0095] In the subsequent ninth step, after stopping the horizontal rotation of the cleaning nozzle part 10, the cleaning nozzle part 10 is returned to the initial rotation angle. In this case, the bidet control part can repeatedly perform the sixth to ninth steps according to the preset number of times, thereby removing all pollution sources from the surface of the bowl 2a of the toilet 2.

[0096] like Fig.10 As shown, the flushing mode S40 is a mode for removing the pollution sources remaining on the surface of the bowl 2a of the toilet 2 after the pollution sources are removed by the deep cleaning mode S30, and may include a tenth step and an eleventh step.

[0097] In the tenth step, the hot water heater is kept turned on or off from step b to heat the cleaning water to hot water within the range of 35°C to 75°C (preferably 40°C) or to keep it at normal temperature without being heated.

[0098] like Fig.15As shown, in the subsequent eleventh step, the cleaning nozzle portion 10 is horizontally rotated at a maximum rotation angle and the discharge flow is guided in a zigzag manner through the first drainage chamber 31 and the second drainage chamber 32 of the injection guide portion 30 formed in the nozzle head 20, so that the injection hole 21 of the nozzle head 20 repeatedly sprays cleaning water or unheated normal temperature water heated to a temperature in the range of 35°C to 75°C (preferably 40°C) onto the surface of the bowl 2a in an up and down swinging manner to remove the pollution source remaining on the surface of the bowl 2a of the toilet 2.

[0099] like Fig.11 As shown, the disinfection mode S50 is a mode for disinfecting the surface of the bowl 2a of the toilet 2 from which the remaining pollution sources have been removed after the flushing mode S40, and may include the twelfth to fourteenth steps.

[0100] In the twelfth step, while keeping the hot water heater turned on or off, disinfectant water (or electrolyzed water) is generated by starting the disinfectant water generating unit provided in the bidet body 1 and heating the disinfectant water to a temperature within the range of 35°C to 75°C (preferably 40°C) or maintaining unheated disinfectant water at room temperature.

[0101] like Fig.16 As shown, in the subsequent thirteenth step, the cleaning nozzle part 10 that has reached the maximum extension moving distance is horizontally rotated, and the discharge flow is guided in a zigzag manner through the drainage chamber 31 formed on the injection guide part 30 in the nozzle head 20. Therefore, the injection hole 21 of the nozzle head 20 repeatedly injects disinfectant water heated to a temperature in the range of 35°C to 75°C (preferably 40°C) or unheated disinfectant water to the surface of the bowl 2a in an up and down swinging manner to complete the cleaning of the bowl 2a of the toilet 2.

[0102] In the subsequent fourteenth step, when the hot water heater is started, it is turned off and the disinfectant water generating unit is turned off, the water supply valve opened by the control from step a is controlled to be closed, the cleaning nozzle unit 10 is stored on the bottom surface of the bidet body 1, and the bidet control unit ends the sequence working mode.

[0103] On the other hand, as a sequential working mode, the bidet control unit controls the soaking mode S10→cleaning mode S20→deep cleaning mode S30→flushing mode S40→disinfection mode S50. When using cleaning water or disinfecting water to clean the pollution source from the bowl 2a of the toilet 2, in each of the sequential working modes, air can also be mixed with the cleaning water or disinfecting water through an air pump. In this case, the air mixing in the soaking mode S10, the flushing mode S40 and the disinfecting mode S50 is controlled to a first mixing amount, and the air mixing in the cleaning mode S20 and the deep cleaning mode S30 is controlled to a second mixing amount greater than the first mixing amount, thereby improving the injection efficiency of the injection hole 21 of the nozzle head 20 in spraying the cleaning water or the disinfecting water in an up and down swinging manner.

[0104] On the other hand, as the sequential working mode described above, it is explained that 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 part 10 is in an extended state and is horizontally rotated to spray cleaning water or disinfecting water in a manner of up and down swinging. However, it is not limited to this literature-style description, and may include a process in which the cleaning nozzle part 10 moves up and down within a range of 180 mm from the initial storage position to the maximum extended movement distance, and the cleaning nozzle part 10 is horizontally rotated by a first rotation angle, a second rotation angle, and a maximum rotation angle of 360° based on an initial rotation angle of 0°, and cleaning water or disinfecting water is sprayed onto the surface of the bowl 2a of the toilet 2 in a manner of up and down swinging, so as to minimize the cleaning blind spot on the surface of the bowl 2a.

[0105] Although the technical concept of the toilet bowl cleaning device and the toilet bowl cleaning method using the same of the present invention has been described in detail above with reference to the accompanying drawings, this is only an exemplary description of the most preferred embodiment of the present invention and does not limit the present invention.

[0106] Therefore, the present invention is not limited to the above-mentioned specific preferred embodiments. Without exceeding the spirit of the present invention as claimed in the claims, technicians in the technical field to which the present invention belongs can implement various modifications, and these changes are also within the scope of the claims.
