Description

Technical Field

[0001] This utility model relates to a water purifier. More specifically, it relates to a water purifier that allows the internal pressure and steam of the hot water tank to be discharged into the storage tank by connecting the vent pipe of the hot water tank to the storage tank. This eliminates the need for a separate auxiliary tank or additional management work, and the adapter module can stably maintain the connection between the vent pipe and the storage tank, thereby further improving ease of use. Background Technology

[0002] Recently, due to the rapid development of industry, environmental pollution has become increasingly serious, with water pollution reaching a severe level. Therefore, in most places such as homes and public institutions, people purify water before drinking it.

[0003] To purify water, households use water purifiers. Typically, a water purifier is connected to the tap water pipe, automatically supplying tap water as the raw water source. The raw water is then filtered through an internal filtration device before being discharged through the outlet.

[0004] Typically, a water purifier's casing contains a filter module for filtering raw water, a cold water tank for receiving and cooling the filtered water, and a hot water tank for receiving and heating the filtered water. The cold and hot water stored in the cold and hot water tanks are selectively supplied according to the user's water usage, resulting in either cold or hot water flowing out through the faucet.

[0005] Because the hot water tank continuously heats the water stored inside, a vent is formed at the top of the tank to release internal pressure. Water vapor from the tank is released through the vent, and depending on the situation, the hot water may also boil over and overflow, also being released through the vent. To prevent hot water from flowing into the interior of the tank through the vent, a vent line is usually connected to it.

[0006] The exhaust line is usually connected to a separate auxiliary tank, allowing hot water to flow into the auxiliary tank.

[0007] When the exhaust pipe is connected by further setting up an auxiliary box, the need for an auxiliary box not only increases the number of parts and complicates the structure, but also increases the inconvenience of use, such as the need to empty the auxiliary box when it is full of hot water, because the auxiliary box needs to be emptied.

[0042] The word “including” as used in this specification means that a particular characteristic, region, integer, step, action, element and / or component is specified, but does not exclude the presence or addition of other particular characteristics, regions, integers, steps, actions, elements, components and / or groups.

[0043] Figure 1 This is a conceptual diagram illustrating the water flow structure of a water purifier according to an embodiment of the present invention.

[0044] One embodiment of the water purifier of the present invention has a water storage tank 200 disposed on the upper part of the housing body, and includes: a cold water tank 400 disposed inside the housing body at the lower part of the water storage tank 200, which cools and stores water supplied from the water storage tank 200; and a hot water tank 500 disposed inside the housing body 100 at the lower part of the water storage tank 200, which heats and stores water supplied from the water storage tank 200.

[0045] The cold water tank 400 and the hot water tank 500 are respectively connected to the water outlet faucet 600. When the water outlet valve 610 is opened by the user's water outlet operation, cold water or hot water is supplied from the cold water tank 400 or the hot water tank 500 and the water is discharged through the water outlet faucet 600.

[0046] Conventional water purifiers typically filter raw water supplied from the outside through a filter module and then store the filtered water in a storage tank. However, in one embodiment of this utility model, the raw water is supplied and stored in a storage tank 200. The raw water supplied from the storage tank 200 is then filtered through a filter module 310 and supplied to a cold water tank 400 and a hot water tank 500.

[0047] Water purifiers that store raw water in a water tank 200 installed on the housing 100 are primarily used in offices and similar locations where there is no tap water. That is, unlike water purifiers used in homes, in spaces such as offices where there is no tap water, raw water cannot be supplied through the water supply pipes. Therefore, users need to directly supply raw water to the water tank inside the purifier, and the raw water stored in the tank is filtered by the water filter before being discharged through the outlet.

[0048] For such a water purifier, when the raw water stored in the water tank 200 is used up, the user needs to refill the water tank 200 with new raw water. For this purpose, the water tank 200 is configured to be detachably connected to the housing body 100. Whenever needed, the user can separate the water tank 200, fill it with tap water, and then reconnect it.

[0049] The water purifier of one embodiment of this utility model can be used in places where there is no tap water pipe, but it can also be used in general household water purifiers, etc., and its use is not limited.

[0050] For ease of explanation, the structure of this utility model will be described below based on a water purifier in which the water storage tank 200 can be detached from the housing body 100.

[0051] like Figure 1 As shown, the water stored in the water storage tank 200 is supplied by the operation of the water supply pump 300. The water supplied by the water supply pump 300 first passes through the filter module 310 and can then be supplied to the cold water tank 400 or the hot water tank 500, or directly to the water tap 600.

[0052] A water outlet valve 610 is installed on the water outlet pipe connected to the water outlet faucet 600. When one of the three water outlet valves 610 is opened by the user, cold water, hot water or room temperature water (purified water) will flow out through the water outlet faucet 600.

[0053] As described in the background section, a vent 510 is formed on the hot water tank 500 to release internal pressure. In the hot water tank 500, the water is heated, causing the internal pressure to rise, and the water may boil and overflow. Therefore, to prevent this phenomenon, a vent line 700 is connected to the vent 510.

[0054] In one embodiment of this utility model, one end of the exhaust pipe 700 is connected to the exhaust port 510 of the hot water tank 500, and the other end is connected to the water storage tank 200. The water storage tank 200 and the exhaust pipe 700 can be connected via an adapter module 800.

[0055] By connecting the exhaust pipe 700 to the exhaust port 510 of the hot water tank 500, the steam from the hot water tank 500 flows into the water storage tank 200 along the exhaust pipe 700, thus ensuring that the hot water tank 500 maintains a stable pressure.

[0056] An on / off valve 710, whose opening and closing action is controlled by a control unit (not shown), can be installed on the exhaust pipe 700. The on / off valve 710 is kept in a normally open state, and its action can be controlled by the control unit to close only when hot water is being discharged. Such an on / off valve 710 can be a normally open solenoid (NOS) valve that closes upon receiving an electrical signal in the normally open state.

[0057] By closing the on / off valve 710 when hot water is flowing out, hot water flows steadily to the faucet 600 during the hot water outflow process and does not flow into the vent pipe 700.

[0058] On the other hand, the water storage tank 200 may include a storage chamber 201 for storing water and an extension chamber 202 that extends horizontally from one side of the upper end of the storage chamber 201, and an exhaust line 700 may be connected to the extension chamber 202.

[0059] In this way, an extended chamber 202, which is different from the storage chamber 201, is formed in the water tank 200. Water is contained in the same way as in the storage chamber 201, and an exhaust line 700 is connected to the extended chamber 202, thereby preventing water from flowing directly from the water tank 200 into the hot water tank 500 through the exhaust line 700.

[0060] As explained above, in one embodiment of the present invention, the water purifier connects the exhaust pipe 700, which is connected to the exhaust port 510 of the hot water tank 500, to the water storage tank 200, eliminating the need for a separate auxiliary tank, thus simplifying the structure and requiring no additional management, making it more convenient to use.

[0061] In particular, according to one embodiment of the present invention, in order to inject water into the water storage tank 200, the water storage tank 200 can be separated from the housing body 100. During this process, the water storage tank 200 can be cleaned and managed, so there is no need for separate additional work related to the exhaust pipe 700, thus making it more convenient to use.

[0062] Next, the connection structure between the water storage tank 200 and the exhaust pipe 700 will be described in more detail.

[0063] Figure 2 This is a schematic cross-sectional view illustrating the connection structure of the exhaust pipe and the water storage tank according to an embodiment of the present invention. Figure 3 Therefore Figure 2The cross-sectional view shown is a schematic cross-sectional view of the water storage tank in a separated state according to an embodiment of the present invention. Figure 4 and Figure 5 This is an enlarged cross-sectional view schematically illustrating the connection structure between the vent pipe and the water tank during the separation and reassembly process of a water tank according to an embodiment of the present invention.

[0064] Figure 2 and Figure 3 The diagram illustrates the connection between the exhaust pipe 700 and the water storage tank 200, with the water storage tank 200, the hot water tank 500, and the exhaust pipe 700 as the central components. Other components are shown in an omitted state.

[0065] like Figure 2 and Figure 3 As shown, the water tank 200 can be detachably attached to the housing body 100. The housing body 100 is provided with a supporting shell 110, which surrounds and supports the water tank 200 when it is attached to the housing body 100. That is, the water tank 200 is attached to the housing body 100 with its upper part open and resting on the supporting shell 110, and detaches from the housing body 100 by moving upwards from the supporting shell 110.

[0066] The water tank 200 is formed as a container with internal storage space and an open top, and the open top of the water tank 200 can be combined with a separate cover 220.

[0067] The water storage tank 200 includes a storage chamber 201 for storing water and an extension chamber 202 extending horizontally from one side of the upper end of the storage chamber 201. Figure 2 As shown, water is stored inside the storage chamber 201 of the water tank 200, while the expansion chamber 202 is maintained as an empty space without stored water.

[0068] An adapter module 800 is mounted on the supporting housing 110. This adapter module 800 connects to the expansion chamber 202 when the water tank 200 is attached to the housing body 100, and an exhaust pipe 700 is connected to the lower part of the adapter module 800. The upper part of the adapter module 800 connects to the expansion chamber 202 of the water tank 200 when the water tank 200 is placed on the supporting housing 110.

[0069] like Figure 4 and Figure 5 As shown, such an adapter module 800 may include an adapter body 810 that is vertically connected to a support housing 110, and a sealing sleeve 830 that is connected to the outer peripheral surface of the adapter body 810.

[0070] The adapter body 810 may have an adapter connection port 811 that can be connected to the water tank 200 at the part that extends upward through the supporting housing 110, and a pipeline connection port 812 that can be connected to the exhaust pipe 700 at the part that extends downward through the supporting housing 110. The sealing sleeve 830 may be formed to surround the outer peripheral surface of the adapter connection port 811.

[0071] On the other hand, corresponding to such an adapter module 800, a water tank connection portion 210 is formed on the water tank 200, which is sealed to the adapter connection port 811 and can be detachably connected, and a steam outlet 213 can be formed at the upper end of the water tank connection portion 210.

[0072] The water tank connection portion 210 may include: an adapter receiving groove 211, which is formed in a concave upward shape on the underside of the water tank 200 so as to accommodate the adapter connection port 811 and the sealing sleeve 830; and a steam exhaust pipe 212, which is formed in a hollow tube extending vertically through the center of the adapter receiving groove 211. The lower end of the steam exhaust pipe 212 may be open, and a steam exhaust port 213 may be formed on one side of the upper end, the upper end of which may be formed to protrude upward from the top of the adapter receiving groove 211.

[0073] Based on this structure, such as Figure 4 and Figure 5 As shown, when the water tank 200 is placed on the support housing 110, the adapter connection port 811 of the support housing 110 is inserted into the adapter receiving groove 211 of the water tank 200. A sealing sleeve 830 may be attached to the outer peripheral surface of the adapter connection port 811, and a sealing wing 831 may be formed protruding around the outer peripheral surface of the sealing sleeve 830 in a circumferential direction so as to be in close contact with the inner peripheral surface of the adapter receiving groove 211.

[0074] The adapter body 810 has an adapter connection port 811 that protrudes upward from the upper part based on the supporting shell 110 and is connected to the adapter receiving slot 211 of the water storage tank 200. It also has a pipeline connection port 812 that protrudes downward from the lower part based on the supporting shell 110 and is connected to the exhaust pipeline 700.

[0075] Because a steam exhaust pipe 212 is formed protruding upward on the adapter receiving slot 211 of the water storage tank 200, therefore... Figure 5 As shown by the dashed arrow, the water vapor flowing from the hot water tank 500 through the exhaust pipe 700 flows through the pipe connection port 812 into the adapter connection port 811, and then flows from the adapter connection port 811 into the steam exhaust pipe 212, and is discharged into the internal space of the water storage tank 200 through the steam exhaust port 213.

[0076] At this time, a sealing sleeve 830 is attached to the outer peripheral surface of the adapter connection port 811 to maintain a sealed state with the inner peripheral surface of the adapter receiving groove 211, thus preventing water vapor flowing in through the vent pipe 700 from leaking out through the space between them. In particular, even if hot water flows in from the hot water tank 500 through the vent pipe 700, hot water leakage is prevented by this sealing structure.

[0077] On the other hand, when the water tank 200 is connected to the adapter module 800, the steam discharge pipe 212 can be formed such that its outer peripheral surface is spaced apart from the inner peripheral surface of the adapter connection port 811, and its lower end surface is spaced upward from the inner bottom surface of the adapter connection port 811.

[0078] By positioning the steam exhaust pipe 212 in the central empty space within the adapter connection port 811, the pressure of the external space SP can be used to further prevent hot water leakage when hot water flows in through the exhaust pipe 700.

[0079] In detail, when hot water boils and overflows from the hot water tank 500 and flows into the exhaust pipe 700, the hot water, like steam, flows through the pipe connection port 812 into the internal space of the adapter connection port 811. As the inflow of hot water increases and passes through the internal space of the adapter connection port 811, the hot water is discharged into the internal space of the storage tank 200 through the steam outlet 213. At this time, the flow process of the hot water is as follows: First, as the hot water flows into the internal space of the adapter connection port 811, the water level in the internal space of the adapter connection port 811 rises. When the water level rises to height H, the air pressure maintained in the external space SP of the sealed steam exhaust pipe 212 causes the hot water to flow only in the direction of the steam exhaust pipe 212 and not into the external space SP of the steam exhaust pipe 212.

[0080] Therefore, by forming the outer peripheral surface and lower end surface of the steam discharge pipe 212 separately from the adapter connection port 811, air pressure can be formed in the external space SP of the steam discharge pipe 212 when hot water flows in, thereby preventing hot water leakage again.

[0081] The above description is merely an exemplary description of the technical solution of this utility model. Those skilled in the art will be able to make various modifications and variations without departing from the essential characteristics of this utility model. Therefore, the embodiments disclosed in this utility model are not intended to limit the technical solution of this utility model, but are for illustrative purposes, and these embodiments do not constitute a limitation on the scope of the technical concept of this utility model.
