Detailed Description

Referring to fig. 2 and 3, the water purifying drinking machine of the present invention includes a housing 10, a water tank 20 disposed at one side of the housing 10, a two-way valve 30, a balance water tank 40, a pump 50, a heater 60, a water drain 70, and a steam guiding 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, has a separable structure and is used for communicating the water tank 20 with the balance water tank 40 when being connected together; after the water tank 20 is taken out, the two-way valve 30 is separated from each other and seals the outlet of the water tank 20 and the inlet of the balancing water tank 40, respectively, to prevent water from flowing out. The pump body 50 pumps the water in the balance tank 40 and supplies the water to the heater 60. The drain 70 draws the hot water in the heater 60 to be provided to the user for drinking. The steam guide device 80 is connected between the balancing water tank 40, the heater 60 and the drain 70 to guide the steam generated from the heater 60.

Wherein the balancing water tank 40, the heater 60, and the drain 70 are all located within the case 10. The heater 60 is provided near the top of the case 10 and provided with a steam discharge port 61. The balance tank 40 is near the bottom of the housing 10. The outlet of the drain pipe 71 of the drain 70 is located outside the housing 10 and is axially perpendicular to the horizontal plane.

Referring to fig. 4, the steam guiding device 80 includes a first connection pipe 81, a second connection pipe 82, a third connection pipe 83, and a three-way valve 84. One end of the first connection pipe 81 is connected to the steam outlet 61, and the other end thereof is connected to the three-way valve 84. One end of the second connection pipe 82 is connected to the three-way valve 84, and the other end is connected to the balance water tank 40. The two ends of the third connecting pipe 83 are respectively a first port 831 and a second port 832. The first port 831 is connected to the drain 70, and the second port 832 is connected to the three-way valve 84. The water purifier is placed on a horizontal table with the bottom located on the side near the table, and the distance from the first port 831 to the table is larger than the distance from the second port 832 to the table, so that the third connecting pipe 83 is inclined with respect to the table toward the three-way valve 84. Further, a third port 821 and a fourth port 822 are provided at both ends of the second connection pipe 82. One end of the third port 821 is connected to the three-way valve 84, and one end of the fourth port 822 is connected to the balance tank 40. Distances from the first port 831, the second port 832, the third port 821 and the fourth port 822 to the table surface are decreased in sequence. Further, the vertical distance of the steam discharge port 61 to the table is greater than the vertical distance of the first port 831 to the table. Further, the steam guiding device 80 further includes a sleeve 85 having an opening at one end. The sleeve 85 is sleeved outside the water drainage pipe 71, and the opening of the sleeve is in the same direction as the outlet of the water drainage pipe 71 and is axially parallel to the axial direction of the water drainage pipe 71. The first port 831 is located on the outer wall of the sleeve 85 such that the third adapter 83 communicates with the inside of the sleeve 85. Preferably, the third adapter 83 is a metal pipe to facilitate the generation of condensed water.

Further, the water purifier of the present invention further includes a first temperature sensor (not shown) and a second temperature sensor (not shown), wherein the first temperature sensor is located in the equilibrium water tank 40 to detect the temperature of the water therein. The second temperature sensor is located at an outlet of the drain pipe 71 to detect a temperature of the supplied water. The temperatures detected by the first temperature sensor and the second temperature sensor are compared to detect whether the heater 60 is working normally. Preferably, the first and second temperature sensors are NTC thermistor temperature sensors.

When the water purifying drinking machine of the present invention is operated, the drinking water in the water tank 20 is filtered and then flows into the balance water tank 40 through the two-way valve 30. The pump body 50 pumps the drinking water in the balance water tank 40 to the heater 60 for heating. The steam generated in the heater 60 is pressed toward the steam outlet 61 by the expansion and contraction of heat, and flows along the first connection pipe 81 to the three-way valve 84. The steam flows upwards to enter the second connecting pipe 82 and is condensed, a part of the steam forms condensed water and flows downwards along the second connecting pipe 82 under the action of gravity, and then flows into the balance water tank 40 through the three-way valve 84 and the third connecting pipe 83 for reheating, and the generation of the steam is reduced. The steam without condensed water is discharged out of the water purifier along the sleeve 85 or the drain pipe 71, so that the diversion of the steam is realized.

The first temperature sensor detects the water temperature in the balance water tank 40, and if the water temperature in the balance water tank 40 is 5-40 ℃, the operation is normal; if the temperature of the water in the balance water tank 40 is higher than 40 ℃, the operation is abnormal, the returned condensed water will affect the heating operation of the heater 60, and the water can be supplied again after the temperature of the water in the balance water tank 40 is reduced to below 40 ℃, so as to protect the heater 60. Meanwhile, the second temperature sensor detects the temperature of the water at the outlet of the drain pipe 71, and compares the detected temperature with the temperature of the water detected by the first temperature sensor to obtain temperature rise data so as to further determine whether the heater 60 works normally.

In the water purifier of the present invention, the volume of the balance tank 40 is smaller than the volume of the water tank 20, and the balance tank 40 protects the pump body 50. In the case where the balancing tank 40 is not provided, the condensed water generated from the heater 60 directly flows back into the water tank 20, which also meets the design intent of the present invention.

Compared with the prior art, the water purifying and drinking machine and the steam guide device thereof can ensure the smooth discharge of steam while reducing the discharge amount of the steam, thereby improving the safety in use. The returned condensed water is supplied again, so that the energy is saved and the environment is protected. And the steam and the water are separated and discharged, so that the instability of water flow is prevented, and the safety is further improved. In addition, a temperature sensor is arranged to prevent the normal operation of the heater from being influenced by the backflow of the condensed water.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the utility model. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
