Description

Technical Field

[0001] The utility model relates to the technical field of drinking water equipment, in particular to a water storage structure of drinking water equipment. Background Art

[0002] Nowadays, water dispensers have become a common drinking water equipment in most urban households and offices. However, there is a common safety hazard in the use of water dispensers. Due to long-term use and pollution from the surrounding environment, a large number of bacteria have grown inside the water dispenser, especially in the cold cylinder and water channel of the water dispenser. The temperature and humidity are suitable for the reproduction and spread of bacteria and viruses. If they are not cleaned and disinfected for a long time, serious drinking water pollution will occur.

[0003] The existing ozone sterilization is a bacteriolysis-level method, which can sterilize thoroughly. However, ozone is a strong oxidant and can damage many items. Most of the devices in water dispensers are made of metal and are easily oxidized. Filtration sterilization can sterilize in time to avoid secondary pollution, but the filtration efficiency is low, it is difficult to discharge water at a large flow rate, and the filter medium also needs to be replaced regularly. In addition, the water quality of existing water dispensers will deteriorate after being left for a long time. Ultraviolet sterilization is low in cost, and the disinfection effect is less affected by water temperature and pH, but it has no continuous sterilization effect. The UV lamp sleeve is prone to scaling, which affects the transmission and sterilization effect of ultraviolet light, and bacteria will revive.

[0004] In addition, when the water in the water tank is used up, a layer of water film usually remains at the bottom of the water tank and cannot be discharged. If the water is not used for a long time, bacteria will grow at the bottom of the water tank. When the water in the water tank is used next time, the bacteria will be supplied to the water channel inside the water tank along with the replenished water, causing pollution to the water channel.

[0037] like Figure 1-6 As shown, the following embodiment discloses a water storage structure of a drinking water device.

[0038] A water storage structure for drinking water equipment, comprising:

[0039] The water tank 100 has a water outlet channel 101 at the bottom thereof;

[0040] The filter assembly 200 is located at the bottom of the water tank 100 and is connected to the water outlet channel 101; the water in the water tank 100 flows out from the water outlet channel 101 after passing through the filter assembly 200;

[0041] A trough 102 is provided at the bottom of the water tank 100 , and the water outlet channel 101 is arranged at the bottom of the trough 102 ; the filter assembly 200 is installed in the trough 102 .

[0042] The above is the basic solution of this embodiment.

[0043] Specific reference Figure 1 and Figure 2 As shown, after water is stored in the water tank 100, when water needs to be supplied to the drinking water equipment, the raw water is filtered by the filter assembly 200 and enters the water storage channel, and water is supplied to the water channel inside the drinking water equipment along the pipeline from the water outlet channel 101.

[0044] Reference Figure 3 As shown, in this embodiment, a sink 102 is provided at the bottom of the water tank 100. When the water supply of the water tank 100 stops and the water tank 100 is in a water shortage state, the raw water at the bottom of the water tank 100 will flow toward the sink 102, gather in the sink 102, and then flow out from the water outlet channel 101;

[0045] Compared with the prior art, in this embodiment, the residual water is treated to prevent water from accumulating at the bottom of the water tank 100 and breeding bacteria, thereby preventing the raw water subsequently replenished into the water tank 100 from being contaminated.

[0046] In order to ensure that the residual water at the bottom of the water tank 100 can flow smoothly into the sink 102 , in this embodiment, a guide surface inclined toward one side of the sink 102 can be provided at the bottom of the water tank 100 .

[0047] In this embodiment, in order to smoothly discharge the residual water, a water gap a is formed between the filter assembly 200 and the bottom of the trough 102 , and the water gap a is connected to the water outlet channel 101 .

[0048] Specifically, in the present embodiment, a groove is provided at the bottom of the filter assembly 200, and a gap is provided at the lower end of the groove. When the filter assembly 200 is installed in the trough 102, the bottom contacts the bottom of the trough 102, and the gap of the groove is blocked by the end face of the bottom of the trough, thereby forming a water gap a. The residual water gathers in the trough 102, and then passes through the water gap a to enter the water outlet channel 101 for discharge.

[0049] In order to prevent water leakage from the water tank 100 , in this embodiment, a one-way valve 300 is provided in the water outlet channel 101 , and the one-way valve 300 is driven to open by an external water pipe of the water tank 100 .

[0050] When the water tank 100 is taken out to replenish raw water, the one-way valve 300 and the water receiving pipe are separated, and the one-way valve 300 is closed at this time; after the water tank 100 is installed in place, the water receiving pipe pushes the one-way valve 300 open, the water outlet channel 101 is opened, and the water tank 100 can supply water to the waterway.

[0051] A valve slot 103 is provided at the bottom of the sink 102 , and the head of the one-way valve 300 is disposed in the valve slot 103 ; the inlet of the water outlet channel 101 passes through the valve slot 103 .

[0052] When the one-way valve 300 is not opened, its head is located in the valve slot 103, blocking the entrance of the water outlet channel 101;

[0053] When the one-way valve is opened, its head is pushed upward by the water receiving pipe to open the entrance of the water outlet channel 101 , and the water in the trough 102 can enter the water outlet channel 101 through the valve groove 103 .

[0054] In this embodiment, the structure of the one-way valve 300 is consistent with the one-way valve 300 used in the water channel in the prior art, and will not be described in detail here.

[0055] In this embodiment, the specific connection mode of the filter assembly 200 and the sink 102 is set as follows: the filter assembly 200 includes a housing 210 with a filter element 230 disposed therein, and the housing 210 is provided with a water channel 211 capable of accommodating water to enter;

[0056] The housing 210 and the sink 102 are fixed via a mounting seat 220 .

[0057] Specific reference Figure 3 and Figure 4 As shown, in order to ensure the stable installation of the filter assembly 200 and the bottom of the water tank 100, in this embodiment, the mounting seat 220 is fixed in the trough 102, and then the outer shell 210 and the mounting seat 220 are fixed, and the filter element 230 is located inside the outer shell 210; the raw water in the water tank 100 enters the outer shell 210 through the water trough 211, and the impurities are retained in the filter element 230 through the action of the filter element 230, and the clean water is output from the bottom of the outer shell 210 to the water outlet channel 101.

[0058] In this embodiment, the mounting seat 220 and the sink 102 are arranged to be detachably connected, and a specific implementation thereof is as follows: a sealing ring 240 is arranged between the mounting seat 220 and the inner wall of the sink 102 .

[0059] When the filter element 230 of the filter assembly 200 needs to be replaced, it is only necessary to take it out from the trough 102 together with the sealing ring 240. After the replacement is completed, the outer shell 210 is installed on the mounting seat 220, and the mounting seat 220 is squeezed into the trough 102.
