Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water purifying machine, in particular to a water purifying machine and a steam guiding device thereof. BACKGROUND

[0002] With the improvement of living standards, people have higher and higher requirements for the quality of drinking water, so the use of water purifying machine is increasingly common. The water purifying machine integrates water purification and temperature control functions. Please refer to Figure 1 , the structure of the existing water purifying machine generally includes a water tank 1, a heating pump 2, a heating body 3 and a water outlet 4 connected in series through pipelines. The heating pump 2 draws the drinking water in the water tank 1 to the heating body 3 to heat to the required temperature, and then the hot water is discharged from the water outlet 4.

[0003] In order to facilitate the user to take water, the water outlet 4 is generally arranged on one side close to the top of the water purifying machine. Correspondingly, the heating body 3 is also arranged on one side close to the top of the water purifying machine. The heating body 3 will generate water vapor during heating. If a large amount of water vapor accumulates in the water purifying machine, it will affect the normal work of other parts, and the water vapor must be discharged outside the machine body. Since the water vapor is in an ascending state, in order to facilitate its discharge, a through hole is generally arranged at the top of the water purifying machine, and the water vapor generated by the heating body 3 is discharged from the through hole. However, the water vapor discharged from the top of the water purifying machine is prone to condensation after being cooled, causing water accumulation at the top of the water purifying machine, and it can also burn the user. In addition, the top of the water purifying machine is also easy to be covered by other objects, causing the water vapor to be unable to be discharged smoothly, which brings certain safety hazards. SUMMARY

[0004] Based on this, the purpose of the present application is to provide a water purifying machine, which guides the steam generated thereby, reduces water accumulation at the top of the water purifying machine, and improves safety.

[0005] The water purifying machine of the present application adopts the following technical scheme:

[0007] Compared with the prior art, the water purifying machine of the present application converts part of the steam into condensed water through the steam guiding device, and guides the remaining steam to the water discharger, thereby reducing the amount of steam discharge, ensuring the smooth discharge of steam, preventing steam from being discharged from the machine body, and improving the safety during use.

[0008] Further, the steam flow guide device comprises a first connecting pipe, a second connecting pipe, a third connecting pipe and a three-way valve; the first connecting pipe is connected between the heater and the three-way valve; the second connecting pipe is connected between the three-way valve and the water tank; the third connecting pipe is connected between the three-way valve and the water drainer; the vertical distance from the outlet of the third connecting pipe to the water surface is greater than the vertical distance from the inlet of the third connecting pipe to the water surface. The inclined third connecting pipe can make the condensed water generated by the steam in the process of rising return along the pipe body, and can guide the steam flow.

[0009] Further, the steam flow guide device further comprises a sleeve with an opening at one end, the sleeve is sleeved outside the outlet of the water drainer, and the opening is in the same direction as the outlet of the water drainer; the third connecting pipe is connected between the sleeve and the three-way valve.

Under the action of gravity, the condensed water returns to the water tank.

[0011] Further, the steam flow guide device further comprises a first temperature sensor arranged in the water tank and a second temperature sensor arranged at the outlet of the water drainer. The first temperature sensor and the second temperature sensor detect the water temperature to determine whether the heater is working normally, so as to prevent the return of the condensed water from affecting the normal work of the heater.

[0024] Please refer to Figure 2 and Figure 3 ​The net drinking machine of the present application comprises a housing 10, a water tank 20 arranged on one side of the housing 10, a two-way valve 30, a balance water tank 40, a pump body 50, a heater 60, a water discharger 70 and a steam guide device 80. The water tank 20 has a filtering function. The two-way valve 30 is a two-way sealing valve in the prior art, which has a split structure and is connected together to communicate the water tank 20 and the balance water tank 40. When the water tank 20 is removed, the two-way valve 30 is separated from each other and seals the outlet of the water tank 20 and the inlet of the balance water tank 40 respectively to prevent water from flowing out. The pump body 50 pumps out the water in the balance water tank 40 and supplies it to the heater 60 for heating. The water discharger 70 extracts the hot water in the heater 60 to provide for the user to drink. The steam guide device 80 is connected between the balance water tank 40, the heater 60 and the water discharger 70 to guide the steam generated by the heater 60.

[0025] The balance water tank 40, the heater 60 and the water discharger 70 are all located in the housing 10. The heater 60 is close to the top of the housing 10 and is provided with a steam discharge outlet 61. The balance water tank 40 is close to the bottom of the housing 10. The outlet of the water discharge pipe 71 of the water discharger 70 is located outside the housing 10 and is axially perpendicular to the horizontal plane. The capacity of the balance water tank 40 is less than that of the water tank 20, and it prevents the dry burning of the heater 60 due to the lack of water in the water tank 20.

[0026] Please refer to Figure 4The steam flow guide 80 includes a first pipe 81, a second pipe 82, a third pipe 83, and a three-way valve 84. The first pipe 81 has one end connected to the steam outlet 61 and the other end connected to the three-way valve 84. The second pipe 82 has one end connected to the three-way valve 84 and the other end connected to the balance tank 40. The third pipe 83 has a first port 831 and a second port 832 at two ends. The first port 831 is connected to the drain 70, and the second port 832 is connected to the three-way valve 84. The net drinking machine is placed on a horizontal table, with its bottom near one side of the table. The distance from the first port 831 to the table is greater than the distance from the second port 832 to the table, so that the third pipe 83 is inclined towards the three-way valve 84 relative to the table. Further, the second pipe 82 has a third port 821 and a fourth port 822 at two ends. The third port 821 is connected to the three-way valve 84, and the fourth port 822 is connected to the balance tank 40. The distances from the first port 831, the second port 832, the third port 821, and the fourth port 822 to the table decrease in turn. Further, the vertical distance from the steam outlet 61 to the table is greater than the vertical distance from the first port 831 to the table. Further, the steam flow guide 80 also includes a sleeve 85 with an opening at one end. The sleeve 85 is sleeved outside the drain pipe 71, with its opening in the same direction as the outlet of the drain pipe 71 and axially parallel to the axis of the drain pipe 71. The first port 831 is located on the outer wall of the sleeve 85, so that the third pipe 83 communicates with the inside of the sleeve 85. Preferably, the third pipe 83 is a metal pipe to facilitate the generation of condensed water.

[0027] Further, the net drinking machine of the present application also includes a first temperature sensor (not shown in the figure) and a second temperature sensor (not shown in the figure). The first temperature sensor is located in the balance tank 40 to detect the water temperature inside. The second temperature sensor is located at the outlet of the drain pipe 71 to detect the water supply temperature. The temperatures detected by the first and second temperature sensors are compared to detect whether the heater 60 is working normally. Preferably, the first and second temperature sensors are NTC thermistor temperature sensors.

[0028] When the water purifier of the present application is in operation, the filtered drinking water in the water tank 20 flows into the balance tank 40 through the two-way valve 30. The pump body 50 pumps the drinking water in the balance tank 40 to the heater 60 for heating. The steam generated in the heater 60 is forced to the steam outlet 61 due to thermal expansion and contraction, and flows along the first connecting pipe 81 to the three-way valve 84. After rising and flowing into the second connecting pipe 82, the steam is condensed, a part of which forms condensed water and flows downward along the second connecting pipe 82 under the action of gravity, and then flows into the balance tank 40 through the three-way valve 84 and the third connecting pipe 83 for heating again and reducing steam generation. The steam that does not form condensed water is discharged to the outside of the water purifier along the sleeve pipe 85 or the drain pipe 71, thereby realizing steam diversion.

[0029] The first temperature sensor detects the temperature of the water in the balance tank 40. If the temperature of the water in the balance tank 40 is 5 to 40 degrees Celsius, it is normal; if the temperature of the water in the balance tank 40 is greater than 40 degrees Celsius, it is abnormal, and the backflow of the condensed water will affect the heating work of the heater 60, so that the water supply should be restarted when the temperature of the water in the balance tank 40 is reduced to below 40 degrees Celsius to protect the heater 60. At the same time, the second temperature sensor detects the temperature of the water at the outlet of the drain pipe 71, and compares it with the temperature detected by the first temperature sensor to obtain temperature rise data to further determine whether the heater 60 is working normally.

[0030] In addition, in the water purifier of the present application, the capacity of the balance tank 40 is smaller than that of the water tank 20, and the balance tank 40 plays a role in protecting the pump body 50. Without the balance tank 40, the condensed water generated by the heater 60 directly flows back into the water tank 20, which also meets the design intention of the present application.

[0031] Compared with the prior art, the water purifier and the steam diversion device thereof of the present application can reduce the amount of steam emission while ensuring the smooth discharge of steam, thereby improving the safety during use. The backflow of the condensed water is used for water supply again, which is energy-saving and environmentally friendly. Moreover, the steam is separated from the water and discharged, which prevents unstable water flow and further improves safety. In addition, the temperature sensor is provided to prevent the backflow of the condensed water from affecting the normal work of the heater.

[0032] The above-described embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it should not be understood as limiting the scope of the patent. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of protection of the present application.
