Description

Technical Field

[0001] This utility model relates to the field of sanitary ware technology, and in particular to an ozone water generator and a toilet. Background Technology

[0002] With the continuous upgrading and optimization of modern toilets, consumers are increasingly pursuing a higher quality of life, especially paying close attention to hygiene and safety. In existing technologies, intelligent disinfection toilets typically use high-voltage corona discharge to generate ozone, which is then dissolved in water to form ozonated water. This ozone is used to wash and disinfect the user's buttocks after using the toilet, and can also be used to flush the toilet bowl. However, after ozone is generated through water electrolysis, some ozone cannot dissolve in time and forms bubbles that adhere to the electrode plates, affecting the subsequent electrolysis of water and thus impacting the ozone generation efficiency. Utility Model Content

[0003] The main purpose of this invention is to propose an ozone water generator, aiming to solve the technical problem of how to improve the ozone generation efficiency of the ozone water generator.

[0004] To achieve the above objectives, the ozone water generator proposed in this utility model includes:

[0005] The housing has an inlet, an outlet, and a flow channel connecting the inlet and the outlet;

[0006] An electrode plate assembly is installed in the flow channel. The electrode plate assembly includes a positive electrode plate and a negative electrode plate arranged opposite each other. A through hole is formed on the surface of the positive electrode plate.

[0007] Optionally, there may be multiple vias distributed on the surface of the positive electrode plate.

[0008] Optionally, the diameter of the via is set to 2 mm to 3 mm.

[0009] Optionally, the housing includes a first sidewall and a second sidewall disposed opposite to each other along its length. The inlet and outlet are both located on the first sidewall. The negative electrode plate divides the flow channel into an inlet channel and an outlet channel. The inlet is connected to the inlet channel, and the outlet is connected to the outlet channel. A flow gap is formed between the negative electrode plate and the second sidewall, which connects the inlet channel and the outlet channel. There are two positive electrode plates, one of which is located in the inlet channel and the other in the outlet channel.

[0010] Optionally, the two positive plates are connected by a conductive element.

[0011] Optionally, the housing has a bottom plate, the bottom plate has a protruding fixing block, the fixing block has a fixing groove, and the bottom sides of the positive electrode plate and the negative electrode plate are embedded in the fixing groove.

[0012] Optionally, the housing includes a bottom shell and a top cover. The water inlet, water outlet, and flow channel are all located on the bottom shell. The top of the bottom shell has an installation port communicating with the flow channel. The installation port is used to allow the electrode plate assembly to be installed into the flow channel. The top cover is sealed at the installation port. The top cover has two electrode ports, which are respectively used to allow the positive and negative terminals of the power supply to extend into the flow channel.

[0013] Optionally, the ozone water generator further includes a salt immersion unit, which has an inlet, an outlet, and a flow chamber connecting the inlet and the outlet. The flow chamber is used to contain salt, and the outlet is connected to the inlet.

[0014] Optionally, the salt immersion unit includes a housing and a cover. The water inlet, water outlet and flow cavity are provided in the housing. The top of the housing has an opening communicating with the flow cavity. The cover is detachably or movably placed over the opening of the housing to open or close the opening of the housing.

[0015] This utility model also proposes a toilet, including a toilet body, a base, and an ozone water generator as described above. The base is installed in the toilet body, and the ozone water generator is installed inside the base. The inlet of the ozone water generator is used to communicate with a water source or a water tank, and the outlet of the ozone water generator is connected to the flushing flow path of the toilet body and / or the spraying flow path of the base.

[0016] In the technical solution of this ozone water generator, after the electrode plate assembly is energized, the water flowing between the positive and negative electrode plates undergoes electrolysis, thereby producing ozone that dissolves in the water to form ozone water. Some ozone forms bubbles that adhere to the positive electrode plate. The perforations on the positive electrode plate allow water to flow through, enabling water on both sides of the positive electrode plate to flow to the opposite side. This allows for more and more thorough water flow around the positive electrode plate, carrying away more of the bubbles adhering to the plate and reducing their impact on the plate. This ensures the electrolysis efficiency of the electrode plate assembly. Furthermore, the water flow, while carrying away the bubbles, also promotes the dissolution of ozone bubbles in the water, improving the mixing effect of ozone and water. Attached Figure Description

[0028] With the continuous upgrading and optimization of modern toilets, consumers are increasingly pursuing a higher quality of life, especially paying close attention to hygiene and safety. In existing technologies, intelligent disinfection toilets typically use high-voltage corona discharge to generate ozone, which is then dissolved in water to form ozonated water. This ozone is used to wash and disinfect the user's buttocks after using the toilet, and can also be used to flush the toilet bowl. However, after ozone is generated through water electrolysis, some ozone cannot dissolve in time and forms bubbles that adhere to the electrode plates, affecting the subsequent electrolysis of water and thus impacting the ozone generation efficiency.

[0029] This invention proposes an ozone water generator, aiming to solve the technical problem of how to improve the ozone generation efficiency of the ozone water generator.

[0030] In the embodiments of this utility model, such as Figures 1 to 4 As shown, the ozone water generator includes: a housing 10, which has an inlet 11, an outlet 12, and a flow channel connecting the inlet 11 and the outlet 12; and an electrode plate assembly, which is installed in the flow channel. The electrode plate assembly includes a positive electrode plate 21 and a negative electrode plate 22 arranged opposite to each other. The surface of the positive electrode plate 21 has a through hole 211.

[0031] In this embodiment, the housing 10 can form the overall appearance structure of the ozone water generator. The inlet 11 is used to supply water into the flow channel, and the outlet 12 is used to supply water out of the flow channel. When the water flows through the electrode plate assembly in the flow channel, the water located between the positive electrode plate 21 and the negative electrode plate 22 will be electrolyzed to generate ozone. After the ozone is generated, it will flow out of the outlet 12 with the water that has not been electrolyzed. Ozone water not only has strong bactericidal ability, but also decomposes rapidly into oxygen and water after use, without polluting the environment.

[0032] The positive electrode 21 and the negative electrode 22 are conductive metal plates. The positive electrode 21 includes a titanium plate with a rare earth coating on its surface. During water electrolysis, the positive electrode 21 can inhibit oxygen evolution and promote the coupling of oxygen free radicals with oxygen, thereby promoting ozone generation. A through hole 211 is formed on the surface of the positive electrode 21, penetrating the two opposite surfaces of the positive electrode 21 so that water can flow from one side of the positive electrode 21 to the other.

[0033] In the technical solution of this ozone water generator, after the electrode plate assembly is energized, the water flowing between the positive electrode plate 21 and the negative electrode plate 22 undergoes electrolysis, thereby generating ozone that dissolves in the water to form ozone water. Some of the ozone forms bubbles that adhere to the positive electrode plate 21. The through holes 211 on the positive electrode plate 21 allow water to flow through, enabling water on both sides of the positive electrode plate 21 to flow to the opposite side. This allows for more and more thorough water flow around the positive electrode plate 21, enabling the flowing water to carry away more of the bubbles adhering to the positive electrode plate 21, reducing the impact of the bubbles on the positive electrode plate 21, and ensuring the electrolysis efficiency of the electrode plate assembly. In addition, the water flow, while carrying away the bubbles, also promotes the dissolution of ozone bubbles in the water, thereby improving the mixing effect of ozone and water.

[0034] The number of vias 211 can be one, two or more.

[0035] Specifically, such as Figure 2 As shown, there are multiple vias 211 distributed on the surface of the positive electrode plate 21. This increases the number of vias 211 on the positive electrode plate 21, thereby increasing the water flow rate through it. This allows more ozone bubbles attached to various locations on the positive electrode plate 21 to be carried away by the water flow, further improving the electrolysis efficiency of the electrode plate assembly and the mixing effect of ozone and water.

[0036] In practical applications, the diameter of the via 211 is set to 2mm to 3mm, for example, it can be 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm or 3mm.

[0037] For example, such as Figures 2 to 4As shown, the housing 10 includes a first sidewall and a second sidewall arranged opposite to each other along its length. The inlet 11 and the outlet 12 are both opened on the first sidewall. The negative electrode plate 22 divides the flow channel into an inlet channel 131 and an outlet channel 132. The inlet 11 is connected to the inlet channel 131, and the outlet 12 is connected to the outlet channel 132. A flow gap 133 is formed between the negative electrode plate 22 and the second sidewall, and the flow gap 133 connects the inlet channel 131 and the outlet channel 132. There are two positive electrode plates 21, one of which is located in the inlet channel 131 and the other is located in the outlet channel 132.

[0038] The inlet channel 131 and outlet channel 132 are respectively located on both sides of the negative electrode plate 22. After water enters the housing 10 from the inlet 11, it first flows through the inlet channel 131, then through the flow gap 133, and then around the negative electrode plate 22 through the outlet channel 132, finally flowing out from the outlet 12. The two positive electrode plates 21 are respectively arranged opposite to the two plates of the negative electrode plate 22. Both positive electrode plates 21 have through holes 211. The water is electrolyzed for the first time when it flows through the inlet channel 131, and electrolyzed for the second time when it flows through the outlet channel 132. In this way, by reasonably controlling the length of the housing 10, the amount of water electrolyzed in the flow channel can be increased, thereby increasing the amount of ozone generated, improving the electrolysis efficiency of water, and improving the effective filtration of the flow channel space.

[0039] Ozone bubbles formed in the water will float to the surface in the flow channel. The outlet 12 can be positioned higher than the inlet 11 on the first side wall so that when the water flows out of the flow channel, it can carry away more ozone bubbles located in the upper part of the flow channel, thereby improving the effective utilization rate of ozone.

[0040] The two positive plates 21 can be connected to the power supply separately or connected to each other.

[0041] Specifically, such as Figures 2 to 4As shown, the two positive plates 21 are connected by a conductive element 23. Thus, when energizing the positive plates 21, only one of them needs to be energized, simplifying the energizing process. The conductive element 23 can be disposed in the flow gap 133. One end of the conductive element 23 extends to the water inlet channel 131 and connects to one of the positive plates 21, while the other end extends to the water outlet channel 132 and connects to the other positive plate 21. This allows the conductive element 23 to bypass the negative plate 22 and reduces its occupation of other spaces within the housing 10, thereby making the internal structure of the ozone water generating device more compact. The conductive element 23 and the two positive plates 21 can be integrally formed. This simplifies the connection between the conductive element 23 and the two positive plates 21, improves the connection strength between the conductive element 23 and the two positive plates 21, and allows the two positive plates 21 and the conductive element 23 to be installed as a whole into the housing 10 when installing the positive plates 21, thereby improving the ease of installation of the positive plates 21.

[0042] In practical applications, such as Figure 4 As shown, the housing 10 has a base plate with a protruding fixing block 14. The fixing block 14 has a fixing groove 141, and the bottom sides of the positive electrode plate 21 and the negative electrode plate 22 are embedded in the fixing groove 141. In this way, the electrode plate assembly can be fixedly installed in the housing 10, and the fixing and installation method of the electrode plate assembly can be simplified, thereby improving the installation convenience of the electrode plate assembly.

[0043] For example, such as Figure 1 and Figure 2 As shown, the housing 10 includes a bottom shell 15 and a top cover 16. The water inlet 11, the water outlet 12, and the flow channel are all located on the bottom shell 15. The top of the bottom shell 15 has an installation port that communicates with the flow channel. The installation port is used to allow the electrode plate assembly to be installed into the flow channel. The top cover 16 is sealed at the installation port. The top cover 16 has two electrode ports 161, which are used to allow the positive and negative terminals of the power supply to extend into the flow channel, respectively.

[0044] When assembling the ozone water generator, the positive electrode plate 21 and the negative electrode plate 22 can be first inserted into the bottom shell 15 through the mounting port. After the positive electrode plate 21 and the negative electrode plate 22 are in place, the top cover 16 is placed on the mounting port of the bottom shell 15. The top cover 16 and the bottom shell 15 can be fixed by welding to improve the sealing of the connection between the top cover 16 and the bottom shell 15. Before installing the top cover 16, the positive and negative wires of the power supply are first passed through the two electrode ports 161 respectively, so that the positive and negative wires of the power supply are connected to the positive electrode plate 21 and the negative electrode plate 22 respectively. The gap between the power supply wires and the electrode ports 161 can be sealed with a sealing element to prevent water leakage.

[0045] For example, the ozone water generator further includes a salt immersion unit, which has an inlet, an outlet, and a flow chamber connecting the inlet and the outlet. The flow chamber is used to contain salt, and the outlet is connected to the inlet 11.

[0046] Due to differences in water quality across regions, tap water in some areas has a higher resistivity, resulting in lower ozone generation efficiency when the ozone water generator electrolyzes the tap water in those areas. Therefore, when applying the ozone water generator to areas with high tap water resistivity, a salt leaching unit can be installed upstream of the inlet 11. Before flowing into the inlet 11, the tap water will first flow through the flow chamber of the salt leaching unit and come into contact with the salt in the flow chamber, allowing the salt in the tap water to dissolve before flowing into the housing 10. The salt can reduce the resistivity of the water, thereby improving the ozone generation efficiency when the water is electrolyzed in the housing 10.

[0047] Specifically, the salt immersion unit includes a housing and a cover. The water inlet, water outlet, and flow chamber are located within the housing. The top of the housing has an opening communicating with the flow chamber. The cover is detachably or movably positioned over the opening of the housing to open or close it. The salt within the salt immersion unit is consumed after being dissolved by the flowing water multiple times. By opening the housing through the cover, the user can easily replenish the salt in the flow chamber, thus extending the effective working life of the salt immersion unit without requiring replacement, facilitating long-term use.

[0048] This utility model also proposes a toilet, which includes a toilet body, a base and an ozone water generating device. The specific structure of the ozone water generating device is as described in the above embodiments. Since this toilet adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
