Technical Field

[0001] The present application relates to the field of water purification technology, and in particular to a water purification device and a water purifier. Background Art

[0002] The water purification device in the water purifier is used to achieve the filtering effect of the water purifier. In the existing water purification devices, a reverse osmosis membrane filter element is usually used in combination with a booster pump for filtering, which results in a complex structure and a large size of the water purification device. In addition, the booster pump also produces a large noise when working, and the filter element also needs to be replaced regularly, causing many inconveniences to consumers. Utility Model Content

[0003] The present application provides a water purification device and a water purifier, which purify liquid by distillation and condensation, thereby simplifying the structure of the water purification device and reducing the volume of the water purification device.

[0004] The first aspect of the present application provides a water purification device, comprising: a clean water tank; a distillation tank connected to the clean water tank, the distillation tank having a condensation top wall, the condensation top wall gradually tilting downward in the direction from the distillation tank to the clean water tank; a heating device installed in the distillation tank; wherein the steam generated by the liquid in the distillation tank after being heated by the heating device can be cooled by the condensation top wall to form condensed water, and the condensed water can flow into the clean water tank along the condensation top wall.

[0005] In the above scheme, the steam generated by the liquid in the distillation box after being heated by the heating device will rise and contact the condensation top wall, and will be cooled by the condensation top wall to form condensed water. Since the condensation top wall gradually tilts downward in the direction from the distillation box to the clean water tank, the condensed water formed by the steam cooling can be diverted so that the condensed water can flow directly into the clean water tank along the inclined condensation top wall for storage.

[0006] In the present application, the water purification device can purify the liquid by distillation and condensation, that is, to achieve the effect of purification without a filter element. Compared with the traditional purification method using a filter element, it can simplify the structure of the water purification device, reduce the volume of the water purification device, and reduce the cost of the water purification device. Moreover, the filter element generally needs to be used with a booster pump, and the booster pump makes a lot of noise when working. Therefore, the water purification device provided by the present application can also achieve the effect of reducing noise, which is beneficial to improving the user experience. In addition, in the water purification device provided by the present application, the top wall of the distillation box is used to form a condensation top wall, so as to achieve the effect of integrating the condensation plate structure with the distillation box, and there is no need to set up an additional condensation plate structure, which is not only beneficial to simplify the structure of the water purification device, improve the production efficiency of the water purification device, but also beneficial to reduce the production cost of the water purification device.

[0007] In a possible design, the water purification device has a accommodating cavity, in which a partition is arranged, and the accommodating cavity is divided into the clean water tank and the distillation tank by the partition; a top notch is formed between the partition and the condensation top wall, and condensed water formed by cooling the condensation top wall can flow into the clean water tank through the top notch.

[0008] In the above scheme, the clean water tank and the distillation tank are an integrated structure, and the accommodating chamber can be divided into the clean water tank and the distillation tank by a partition. This structure is relatively easy to manufacture, and the capacity of the clean water tank and the distillation tank can be adjusted by changing the position of the partition. It has strong versatility and low manufacturing cost. By setting a top notch between the partition and the condensation top wall, the clean water tank and the distillation tank can be connected.

[0009] In one possible design, the distillation box also has a first side wall, and a first gap is formed between the first side wall and the condensation top wall; the clean water tank has an installation top wall and a second side wall, and a second gap connected to the first gap is formed between the installation top wall and the second side wall, and / or a third gap connected to the first gap is formed between the condensation top wall and the second side wall; the condensed water formed by cooling the condensation top wall can flow into the clean water tank through the first gap, the second gap and / or the third gap.

[0010] In the above scheme, the clean water tank and the distillation tank are independent structures, and the distillation tank and the clean water tank are connected by providing at least one of the second notch and the third notch and the first notch. Moreover, the structure in which the top of the clean water tank is connected to the distillation tank and the condensation top wall guides the condensed water to the top of the clean water tank is conducive to increasing the available volume of the clean water tank, improving the water storage capacity of the clean water tank, and being more convenient for users to use, compared with the structure in which the second side wall is connected to the first side wall and the condensation top wall guides the condensed water from the second side wall to the clean water tank.

[0011] In a possible design, the distillation tank also has a first side wall, which is provided with a first through hole; the clean water tank has a second side wall, which is provided with a second through hole connected to the first through hole; the condensation top wall extends into the clean water tank through the first through hole and the second through hole.

[0012] In the above scheme, the clean water tank and the distillation tank are independent structures. The connection effect between the distillation tank and the clean water tank is achieved by setting the first through hole and the second through hole. The condensed water formed by cooling the condensation top wall can flow into the clean water tank through the first through hole and the second through hole.

[0013] In a possible design, the condensation top wall is fixedly connected to the installation top wall.

[0014] In the above solution, when the condensation top wall is fixedly connected to the installation top wall, it is beneficial to improve the structural strength and stability of the condensation top wall, thereby helping to increase the service life of the water cooling device.

[0015] In a possible design, the outer wall surface of the first side wall is arranged to fit the outer wall surface of the second side wall.

[0016] In the above solution, the overall structure of the water purification device is more compact, which is conducive to reducing the volume of the water purification device. In addition, the distillation box and the water tank are arranged close to each other, which can shorten the path of condensed water flowing from the distillation box to the water tank and improve the collection efficiency of condensed water.

[0017] In a possible design, the clean water tank is detachably connected to the distillation tank.

[0018] In the above solution, the clean water tank can be detachably connected to the distillation tank, which is convenient for the user to clean the clean water tank and the distillation tank separately, which is beneficial to improving the safety of the water purification device and avoiding the growth of bacteria due to long-term cleaning failure.

[0019] In a possible design, the water purification device also includes a cooling fan and a plurality of heat sinks, wherein the plurality of heat sinks are installed at intervals on the outer wall surface of the condensation top wall; the cooling fan is installed on the installation top wall; and the air outlet direction of the cooling fan is perpendicular to the arrangement direction of the plurality of heat sinks.

[0020] In the above scheme, by providing multiple heat sinks, the heat volatilization on the condensation top wall can be accelerated, so as to achieve the effect of rapidly cooling the condensation top wall, thereby improving the condensation efficiency of the condensation top wall for steam, and further facilitating the water purification efficiency of the water purification device. The heat dissipation fan can dissipate heat from multiple heat sinks at the same time to accelerate the removal of heat from the multiple heat sinks, thereby further accelerating the volatilization of heat on the condensation top wall. When the heat dissipation fan is fixedly installed on the installation top wall, its position can be closer to the heat sink, which is beneficial to improving the heat dissipation effect of the heat dissipation fan, and can also further improve the compactness of the structure of the water purification device, which is beneficial to saving the space occupied by the water purification device.

[0021] In a possible design, the clean water tank is equipped with a high liquid level sensor and a low liquid level sensor, and the high liquid level sensor is located above the low liquid level sensor; the water purification device also includes a water pump and a control panel, and the water pump is connected to the distillation tank for pumping external liquid into the distillation tank; the high liquid level sensor, the low liquid level sensor and the water pump are respectively electrically connected or signal-connected to the control panel; the control panel is used to receive the detection signal of the low liquid level sensor, and control the water pump to turn on according to the detection signal of the low liquid level sensor; the control panel is also used to receive the detection signal of the high liquid level sensor, and control the water pump to turn off according to the detection signal of the high liquid level sensor.

[0022] In the above scheme, when the water pump is turned on, the external liquid can be pumped into the distillation box to realize the rapid filling of the distillation box. The control panel can process the signal of the low liquid level sensor and compare it with the preset signal reference value of the minimum liquid level. According to the comparison result, it is judged whether the liquid level in the clean water tank is lower than the preset minimum liquid level. When the liquid level in the clean water tank is lower than the preset minimum liquid level, the control panel can control the water pump to start so as to inject liquid into the distillation box. At the same time, the control panel can also control the heating device to start so as to distill the liquid in the distillation box, so as to ensure that enough condensed water can flow into the clean water tank; similarly, the control panel can process the signal of the high liquid sensor and compare it with the preset signal reference value of the maximum liquid level. According to the comparison result, it is judged whether the liquid level in the clean water tank is higher than the preset maximum liquid level. When the liquid level in the clean water tank is higher than the preset maximum liquid level, the control panel can control the water pump and the heating device to close so as to avoid the continued generation of condensed water and cause the liquid in the clean water tank to continue to rise. By setting a high liquid level sensor and a low liquid level sensor to connect with the control panel, automatic control of the water purification device can be achieved, ensuring that there is always water in the water purification tank, which can improve the user experience.

[0023] A second aspect of the present application provides a water purifier, comprising the water purifier described above.

[0024] In the above solution, the water purifier achieves water purification through distillation and condensation, which is beneficial to reduce the noise of the water purifier when it is working, and there is no need to replace the filter element regularly, which is beneficial to reduce the user's maintenance costs and improve the user's experience.

[0060] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0061] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0062] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0063] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0064] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0065] The present application provides a water purification device which can be used in a water purifier, such as Figure 1 and Figure 2 As shown, the water purification device comprises a water purification tank 1, a distillation tank 2 and a heating device 3 installed in the distillation tank 2. The distillation tank 2 is used to contain the liquid to be purified, and the heating device 3 is used to heat the liquid in the distillation tank 2. Figure 3 and Figure 4As shown, the distillation box 2 is connected to the clean water tank 1, and the distillation box 2 has a condensation top wall 21. The condensation top wall 21 can be made of a metal material with good heat dissipation and cooling effects, such as Figure 4 As shown by the arrows in the figure, the steam generated after the liquid in the distillation box 2 is heated by the heating device 3 will rise and contact the condensation top wall 21, and will be cooled by the condensation top wall 21 to form condensed water. Since the condensation top wall 21 gradually tilts downward in the direction from the distillation box 2 to the clean water tank 1, the condensed water formed by the steam cooling can be guided so that the condensed water can flow directly into the clean water tank 1 along the tilted condensation top wall 21 for storage.

[0066] The water purification device provided in this embodiment can purify liquid by distillation and condensation, that is, to achieve the effect of purification without a filter element. Compared with the traditional purification method using a filter element, it can simplify the structure of the water purification device, reduce the volume of the water purification device, and reduce the cost of the water purification device. Moreover, the filter element generally needs to be used with a booster pump, and the booster pump makes a lot of noise when working. Therefore, the water purification device provided in this embodiment can also achieve the effect of reducing noise, which is beneficial to improving the user experience. In addition, in the water purification device provided in this embodiment, the top wall of the distillation box 2 is used to form a condensation top wall 21, so as to achieve the effect of integrating the condensation plate structure with the distillation box 2, and there is no need to set up an additional condensation plate structure, which is not only beneficial to simplifying the structure of the water purification device and improving the production efficiency of the water purification device, but also beneficial to reducing the production cost of the water purification device.

[0067] The heating device 3 can be fixed to the outer wall surface of the bottom wall of the distillation box 2, and conduct heat to the inside through the bottom wall of the distillation box 2 to heat the liquid. The heating device 3 can be Figure 2 The heating tube shown has the advantages of high heating efficiency and low manufacturing cost. The specific shape of the heating tube is not limited in this embodiment. Alternatively, the heating device 3 can also be a heating film, a ceramic heating element or other heating element, which is not limited in this embodiment.

[0068] like Figure 2 and Figure 3 As shown, the clean water tank 1 is also provided with a clean water outlet 14, and the clean water in the clean water tank 1 can flow out through the clean water outlet 14 for use by users.

[0069] The clean water tank 1 and the distillation tank 2 may be an integrated structure, such as Figure 6 As shown, the water purification device is a box structure and has a receiving chamber 10, and a partition 20 is arranged in the receiving chamber 10. The receiving chamber 10 can be divided into a clean water tank 1 and a distillation tank 2 by the partition 20. This structure is relatively easy to manufacture. The partition 20 can be fixed in the receiving chamber 10 by welding or other means, and the capacity of the clean water tank 1 and the distillation tank 2 can be adjusted by changing the position of the partition 20, and the versatility is relatively strong.

[0070] Specifically, a top notch 201 is formed between the partition 20 and the condensation top wall 21 , and the clean water tank 1 and the distillation tank 2 are connected through the top notch 201 , and the condensed water formed by cooling the condensation top wall 21 can flow into the clean water tank 1 through the top notch 201 .

[0071] The clean water tank 1 and the distillation tank 2 may also be two independent box structures, and the two may be made of different materials. For example, the clean water tank 1 may be made of a material with better antibacterial effect to reduce the risk of bacteria re-growth in the purified liquid, and the distillation tank 2 may be made of a material with better thermal conductivity to improve the heating efficiency of the liquid in the distillation tank 2, thereby helping to improve the distillation efficiency of the water purification device.

[0072] The following is a detailed description of the structure when the water purification tank 1 and the distillation tank 2 are two independent boxes:

[0073] In a specific embodiment, Figure 8 As shown, the distillation box 2 also has a first side wall 22, and the first side wall 22 is provided with a first through hole 221. The clean water tank 1 has a second side wall 12, and the second side wall 12 is provided with a second through hole 121 communicating with the first through hole 221. The condensation top wall 21 extends into the clean water tank 1 through the first through hole 221 and the second through hole 121. The condensed water formed by cooling the condensation top wall 21 can flow into the clean water tank 1 through the first through hole 221 and the second through hole 121. Therefore, the connection effect between the distillation box 2 and the clean water tank 1 is achieved by providing the first through hole 221 and the second through hole 121.

[0074] In another specific embodiment, Figure 4 and Figure 5 As shown, the distillation box 2 has a first side wall 22, and a first gap 23 is formed between the first side wall 22 and the condensation top wall 21, so that condensed water formed by cooling the condensation top wall 21 can flow out of the distillation box 2 through the first gap 23. At the same time, the clean water tank 1 has an installation top wall 11 and a second side wall 12, and a second gap 13 is formed between the installation top wall 11 and the second side wall 12, and / or a third gap 24 connected to the first gap 23 is formed between the condensation top wall 21 and the second side wall 12, and the condensed water formed by cooling the condensation top wall 21 can flow into the clean water tank 1 through the first gap 23, the second gap 13 and / or the third gap 24.

[0075] Specifically, as shown in Figure 7(a), when the bottom end of the condensation top wall 21 is aligned with the first side wall 22 along the height direction Z of the water purification device, the condensed water can flow into the water purification tank 1 through the first notch 23 and the second notch 13; as shown in Figure 7(b), when the bottom end of the condensation top wall 21 is aligned with the bottom wall of the water purification tank 1 along the height direction Z of the water purification device, the condensed water can flow into the water purification tank 1 through the first notch 23 and the third notch 24; as shown in Figure 7(c), when the bottom end of the condensation top wall 21 is aligned with the second side wall 12 along the height direction Z of the water purification device, the condensed water can flow into the water purification tank 1 through the first notch 23, the third notch 24 and the second notch 13 in sequence.

[0076] Therefore, by providing at least one of the second notch 13 and the third notch 24 and the first notch 23, the distillation tank 2 and the clean water tank 1 are connected. The specific arrangement of the first notch 23, the second notch 13 and the third notch 24 depends on the relative positional relationship between the bottom end of the condensation top wall 21 and the first side wall 22 and the second side wall 12.

[0077] Specifically, Figure 5 As shown, the bottom end of the condensation top wall 21 can extend to the top of the clean water tank 1 to ensure that the condensed water can accurately flow into the clean water tank 1, thereby improving the diversion effect of the condensation top wall 21. Moreover, the structure in which the top of the clean water tank 1 is connected to the distillation tank 2 and the condensation top wall 21 guides the condensed water to the top of the clean water tank 1 is conducive to increasing the available volume of the clean water tank 1, improving the water storage capacity of the clean water tank 1, and being more convenient for users to use, compared with the structure in the previous embodiment.

[0078] like Figure 5 As shown, the outer wall surface of the first side wall 22 is arranged in close contact with the outer wall surface of the second side wall 12, that is, the distillation box 2 is arranged adjacent to the water purification tank 1, so that the overall structure of the water purification device is more compact, which is conducive to reducing the volume of the water purification device. In addition, the distillation box 2 is arranged adjacent to the water tank 1, which can shorten the path of the condensed water flowing from the distillation box 2 to the water tank 1, and improve the collection efficiency of the condensed water.

[0079] Among them, the first side wall 22 and the second side wall 12 can be fixedly connected, that is, the distillation box 2 and the clean water tank 1 can be a relatively fixed structure, or the first side wall 22 and the second side wall 12 can only be in surface contact without being directly connected, that is, the clean water tank 1 and the distillation box 2 can move relative to each other, and this embodiment does not impose any restrictions on this.

[0080] Furthermore, the clean water tank 1 can be detachably connected to the distillation tank 2, so that the user can clean the clean water tank 1 and the distillation tank 2 separately, which is beneficial to improving the safety of the water purification device and avoiding the growth of bacteria due to long-term cleaning failure.

[0081] In a specific embodiment, Figure 5As shown, the condensation top wall 21 is fixedly connected to the installation top wall 11. Compared with the structure with the bottom suspended, when it is fixedly connected to the installation top wall 11, it is beneficial to improve the structural strength and stability of the condensation top wall 21, thereby helping to increase the service life of the water cooling device.

[0082] In a specific embodiment, Figure 4 As shown, the water purification device further includes a plurality of heat sinks 4, which are installed at intervals on the outer wall surface of the condensation top wall 21. By providing a plurality of heat sinks 4, the heat volatilization on the condensation top wall 21 can be accelerated, so as to achieve the effect of rapidly cooling the condensation top wall 21, thereby improving the condensation efficiency of the condensation top wall 21 for steam, and further facilitating the improvement of the water purification efficiency of the water purification device. Specifically, the heat sink 4 can be made of a metal material with good heat dissipation effect.

[0083] Furthermore, if Figure 4 As shown, the water purification device may further include a heat dissipation fan 5, the air outlet direction of the heat dissipation fan 5 being perpendicular to the arrangement direction of the plurality of heat sinks 4, so that the heat dissipation fan 5 can dissipate heat from the plurality of heat sinks 4 at the same time, so as to accelerate the removal of heat from the plurality of heat sinks 4, thereby further accelerating the volatilization of heat from the condensation top wall 21. Specifically, the heat dissipation fan 5 can be fixedly mounted on the mounting top wall 11, close to the heat sink 4, which is conducive to improving the heat dissipation effect of the heat dissipation fan 5, and can also further improve the compactness of the structure of the water purification device, which is conducive to saving the space occupied by the water purification device.

[0084] In a specific embodiment, Figure 1 and Figure 2 As shown, the water purification device further comprises a water pump 7, the water inlet 71 of the water pump 7 is connected to the external water tank, and the water outlet 72 is connected to the distillation box 2. When the water pump 7 is turned on, the external liquid can be pumped into the distillation box 2 to achieve rapid water filling of the distillation box 2.

[0085] In a specific embodiment, Figure 4As shown, the clean water tank 1 is installed with a high liquid level sensor 8 and a low liquid level sensor 9. The high liquid level sensor 8 is located above the low liquid level sensor 9. The high liquid level sensor 8 and the low liquid level sensor 9 are used to detect the liquid level in the clean water tank 1. Specifically, the installation height of the low liquid level sensor 9 in the clean water tank 1 is the preset minimum liquid level. When the liquid level in the clean water tank 1 is lower than the low liquid level sensor 9 and when it is higher than the low liquid level sensor 9, the signal generated by the low liquid level sensor 9 is different. Therefore, by detecting the signal of the low liquid level sensor 9, it is possible to determine whether the liquid level in the clean water tank 1 is too low. Similarly, the installation height of the high liquid level sensor 8 in the clean water tank 1 is the preset maximum liquid level. When the liquid level in the clean water tank 1 is lower than the high liquid level sensor 8 and when it is higher than the high liquid level sensor 8, the signal generated by the high liquid level sensor 8 is also different. Therefore, by detecting the signal of the high liquid level sensor 8, it is possible to determine whether the liquid in the clean water tank 1 is too high. The control board 6 is used to receive

[0086] The water purification device also includes a control board 6, and a high liquid level sensor 8, a low liquid level sensor 9, a heating device 3 and a water pump 7 are respectively electrically connected or signal-connected to the control board 6. The control board 6 is used to receive the detection signal of the low liquid level sensor 9, and control the water pump 7 and the heating device 3 to turn on according to the detection signal of the low liquid level sensor 9; the control board 6 is also used to receive the detection signal of the high liquid level sensor 8, and control the water pump 7 and the heating device 3 to turn off according to the detection signal of the high liquid level sensor 8, so as to realize automatic control of the water purification device.

[0087] Specifically, the control panel 6 can process the signal of the low liquid level sensor 9 and compare it with the preset signal reference value of the minimum liquid level, and judge whether the liquid level in the clean water tank 1 is lower than the preset minimum liquid level according to the comparison result. When the liquid level in the clean water tank 1 is lower than the preset minimum liquid level, the control panel 6 can control the water pump 7 to start so as to inject liquid into the distillation tank 2. At the same time, the control panel can also control the heating device 3 to start so as to distill the liquid in the distillation tank 2, thereby ensuring that enough condensed water can flow into the clean water tank 1. Similarly, the control panel 6 can process the signal of the high liquid sensor 8 and compare it with the preset signal reference value of the maximum liquid level, and judge whether the liquid level in the clean water tank 1 is higher than the preset maximum liquid level according to the comparison result. When the liquid level in the clean water tank 1 is higher than the preset maximum liquid level, the control panel 6 can control the water pump 7 and the heating device 3 to shut down so as to avoid the continued generation of condensed water and cause the liquid in the clean water tank 1 to continue to rise. By providing a high liquid level sensor 8 and a low liquid level sensor 9 connected to the control board 6, automatic control of the water purification device can be achieved, ensuring that there is always water in the water purification tank 1, which can improve the user experience.

[0088] In addition, the control board 6 can also be electrically connected or signal connected to the cooling fan 5. When the liquid level in the clean water tank 1 is lower than the preset minimum liquid level, the control board 6 is used to control the cooling fan 5 to turn on to speed up the condensation efficiency of the condensation top wall 21; when the liquid level in the clean water tank 1 is higher than the preset maximum liquid level, the control board 6 can control the cooling fan 5 to turn off, which can not only realize automatic control of the cooling fan 5, but also achieve energy-saving effects.

[0089] Specifically, Figure 4 As shown, the control board 6 can be fixedly installed on the top of the cooling fan 5. Reasonable use of the space above the heat sink 4 can further improve the compactness of the water purification device. It should be noted that a certain gap should be retained between the control board 6 and the heat sink 4 to ensure that the heat sink 4 can dissipate heat normally.

[0090] The embodiments of the present application also provide a water purifier, which includes the water purifier described in the above embodiments. It realizes water purification by distillation and condensation, which is beneficial to reduce the noise of the water purifier during operation, and there is no need to replace the filter element regularly, which is beneficial to reduce the user's maintenance costs and improve the user's experience.
