Description

Technical Field

[0001] The present invention relates to the technical field of household electrical appliances, and in particular to a heat exchange system and a water outlet device. Background Art

[0002] With economic development and the improvement of living standards, consumers pay more attention to healthy water use and drinking water, and have higher and higher requirements for water use. As a water treatment device that can deeply filter and purify water, water purifiers are recognized and favored by more and more consumers.

[0003] In order to meet people's demand for drinking hot water at any time, water purification equipment includes a heating unit in addition to a filtering unit. Its main working principle is that the raw water is first filtered by the filtering unit, then heated by the heating unit, and then connected to the faucet to achieve the function of hot water output. However, the existing water purification equipment has low heat exchange efficiency and small water flow, which cannot meet the needs of users. Summary of the invention

[0004] In view of this, the present invention provides a heat exchange system and a water outlet device to solve the problems of low heat exchange efficiency, small water flow rate and failure to meet user needs of existing water purification equipment.

[0005] In a first aspect, the present invention provides a heat exchange system for a water outlet device, wherein the water outlet device has a water supply module, and the water supply module supplies water to the heat exchange system, wherein the heat exchange system comprises:

[0006] ontology;

[0007] At least one group of heat exchange modules is arranged on the main body, and each group of heat exchange modules includes a first heat exchange component and a second heat exchange component. The first heat exchange component and the second heat exchange component both use hot water to preheat normal temperature water and cool the hot water into warm boiled water.

[0008] Beneficial effect: The heat exchange system of the present invention includes a main body and at least one group of heat exchange modules, each group of heat exchange modules includes a first heat exchange component and a second heat exchange component, the first heat exchange component and the second heat exchange component both use hot water to preheat water at room temperature, and cool the hot water into warm boiled water (cooked water) at the same time. By setting at least one group of heat exchange modules, and each group of heat exchange modules includes two heat exchange components, the heat exchange efficiency of the heat exchange system can be significantly improved, and the water flow rate of the heat exchange system can be increased, so as to achieve the purpose of preparing a large amount of cooked water in a short time, thereby shortening the waiting time for users to get water.

[0009] In an optional embodiment, the first heat exchange component includes a first heat exchange component first tube and a first heat exchange component second tube, one of the first heat exchange component first tube inlet and the first heat exchange component second tube inlet is connected to the normal temperature water outlet of the water supply module, and the other is connected to the hot water outlet of the water supply module, and correspondingly, one of the first heat exchange component first tube outlet and the first heat exchange component second tube outlet is a first-level preheated water outlet or a first-level preheated water outlet, and the other is a first-level warm boiled water outlet or a first-level warm boiled water outlet;

[0010] The second heat exchange component includes a first tube of a second heat exchange component and a second tube of a second heat exchange component, one of the first tube inlet of the second heat exchange component and the second tube inlet of the second heat exchange component is connected to the first-level preheated water outlet, and the other is connected to the first-level warm boiled water outlet. Accordingly, one of the first tube outlet of the second heat exchange component and the second tube outlet of the second heat exchange component is a second-level preheated water outlet, and the other is a second-level warm boiled water outlet; or one of the first tube inlet of the second heat exchange component and the second tube inlet of the second heat exchange component is connected to the normal temperature water outlet, and the other is connected to the hot water outlet. Accordingly, one of the first tube outlet of the second heat exchange component and the second tube outlet of the second heat exchange component is a second-level preheated water outlet, and the other is a second-level warm boiled water outlet.

[0011] Beneficial effects: In the heat exchange system of the present invention, the first heat exchange component and the second heat exchange component are both sleeve-type heat exchange structures, and the first heat exchange component and the second heat exchange component can be connected in series or in parallel. When the first heat exchange component and the second heat exchange component are connected in series, one of the first pipe inlet of the second heat exchange component and the second pipe inlet of the second heat exchange component is connected to the primary preheated water outlet, and the other is connected to the primary warm water outlet. Correspondingly, one of the first pipe outlet of the second heat exchange component and the second pipe outlet of the second heat exchange component is a secondary preheated water outlet, and the other is a secondary warm water outlet. In this series connection mode, after heat exchange through the first heat exchange component, the normal temperature water becomes the first-level preheated water, and the hot water becomes the first-level warm boiled water. The first-level preheated water and the first-level warm boiled water will enter the second heat exchange component for heat exchange, and the first-level preheated water will further become the second-level preheated water (the water temperature of the second-level preheated water is usually higher than the water temperature of the first-level preheated water), and the first-level warm boiled water will further become the second-level warm boiled water (the water temperature of the second-level warm boiled water is usually lower than the water temperature of the first-level warm boiled water). That is, after heat exchange between the first heat exchange component and the second heat exchange component, the water temperatures of the preheated water and the warm boiled water become closer and closer, so that the hot water can be cooled to a greater extent, and a wider range of water temperature regulation can be achieved to meet the user's needs for different cooked water temperatures.

[0012] When the first heat exchange component and the second heat exchange component are connected in parallel, one of the first pipe inlet of the second heat exchange component and the second pipe inlet of the second heat exchange component is connected to the normal temperature water outlet, and the other is connected to the hot water outlet. Accordingly, one of the first pipe outlet of the second heat exchange component and the second pipe outlet of the second heat exchange component is the second first-level preheated water outlet, and the other is the second first-level warm boiled water outlet. In this parallel connection mode, the normal temperature water and hot water of the water supply module enter the first heat exchange component and the second heat exchange component at the same time. The first heat exchange component and the second heat exchange component simultaneously preheat the normal temperature water and cool the hot water. This heat exchange mode can further improve the heat exchange efficiency, provide users with a large amount of cooked water in a short time, reduce the waiting time for users to get water, and improve the user experience.

The longer the axial length of the first tube of the second heat exchange assembly and the second tube of the second heat exchange assembly, the longer the heat exchange path between the first tube of the second heat exchange assembly and the second tube of the second heat exchange assembly, which is conducive to sufficient heat exchange between the two.

[0081] In the first heat exchange component 2, the functions of the first tube of the first heat exchange component and the second tube of the first heat exchange component can be interchanged. For example, the first tube of the first heat exchange component is connected to normal temperature water and the second tube of the first heat exchange component is connected to hot water, or the first tube of the first heat exchange component is connected to hot water and the second tube of the first heat exchange component is connected to normal temperature water. The selection can be made according to the heat exchange needs. Similarly, in the second heat exchange component 3, the functions of the first tube of the second heat exchange component and the second tube of the second heat exchange component can be interchanged. For example, the first tube of the second heat exchange component is connected to normal temperature water and the second tube of the second heat exchange component is connected to hot water, or the first tube of the second heat exchange component is connected to hot water and the second tube of the second heat exchange component is connected to normal temperature water. The selection can be made according to the heat exchange needs.

[0082] The first heat exchange component 2 and the second heat exchange component 3 can be connected in series or in parallel.

[0083] When the first heat exchange component 2 and the second heat exchange component 3 are connected in series, the first heat exchange component 2 is used to realize the first-level heat exchange, and the second heat exchange component 3 is used to realize the second-level heat exchange. At this time, in the first heat exchange component 2, one of the first heat exchange component first pipe inlet 201 and the first heat exchange component second pipe inlet 202 is connected to the normal temperature water outlet of the water supply module, and the other is connected to the hot water outlet of the water supply module. Correspondingly, one of the first heat exchange component first pipe outlet 203 and the first heat exchange component second pipe outlet 204 is a first-level preheated water outlet, and the other is a first-level warm water outlet. In the second heat exchange component 3, one of the second heat exchange component first pipe inlet 301 and the second heat exchange component second pipe inlet 302 is connected to the first-level preheated water outlet, and the other is connected to the first-level warm water outlet. Correspondingly, one of the second heat exchange component first pipe outlet 303 and the second heat exchange component second pipe outlet 304 is a second-level preheated water outlet, and the other is a second-level warm water outlet.

[0084] In this series connection mode, after heat exchange in the first heat exchange component 2, the room temperature water becomes the first-level preheated water, and the hot water becomes the first-level warm boiled water. The first-level preheated water and the first-level warm boiled water will continue to enter the second heat exchange component 3 for heat exchange, and the first-level preheated water will further become the second-level preheated water (the water temperature of the second-level preheated water is usually higher than the water temperature of the first-level preheated water), and the first-level warm boiled water will further become the second-level warm boiled water (the water temperature of the second-level warm boiled water is usually lower than the water temperature of the first-level warm boiled water). That is, after heat exchange between the first heat exchange component and the second heat exchange component, the water temperatures of the preheated water and the warm boiled water become closer and closer, so that the cooling range of the hot water is larger, and a wider range of water temperature regulation can be achieved to meet the user's needs for different cooked water temperatures.

[0085] In this embodiment, the first pipe of the first heat exchange component is connected to normal temperature water, the second pipe of the first heat exchange component is connected to hot water, the first pipe of the second heat exchange component is connected to primary preheated water, and the second pipe of the second heat exchange component is connected to primary warm boiled water.

[0087] The first tube of the first heat exchange component is sleeved on the outside of the second tube of the first heat exchange component. Normal temperature water is passed into the first tube of the first heat exchange component, while hot water is passed into the second tube of the first heat exchange component. The normal temperature water in the first tube of the first heat exchange component and the hot water in the second tube of the first heat exchange component exchange heat through the tube wall of the second tube of the first heat exchange component, gradually heating up the normal temperature water in the first tube of the first heat exchange component and preheating the normal temperature water, while cooling down the hot water in the second tube of the first heat exchange component.

[0088] The tube wall of the second tube of the first heat exchange component should be made of a material that can transfer heat. In this embodiment, the second tube of the first heat exchange component is formed by a metal tube, that is, the tube wall of the second tube of the first heat exchange component is made of metal, and the internal space of the metal tube is the second tube of the first heat exchange component to ensure heat exchange efficiency.

[0089] In this embodiment, the first tube of the first heat exchange assembly and the second tube of the first heat exchange assembly are coaxially arranged to make the water flow space between the inner wall of the first tube of the first heat exchange assembly and the outer wall of the second tube of the first heat exchange assembly uniform.

[0090] In other embodiments, the second tube of the first heat exchange component may also be sleeved on the outside of the first tube of the first heat exchange component.

[0091] Similarly, the first tube of the second heat exchange component is sleeved on the outside of the second tube of the second heat exchange component, and normal temperature water or first-level preheated water (normal temperature water with higher temperature) is passed into the first tube of the second heat exchange component, while hot water or first-level warm boiled water (hot water with lower temperature) is passed into the second tube of the second heat exchange component. The normal temperature water or first-level preheated water in the first tube of the second heat exchange component and the hot water or first-level warm boiled water in the second tube of the second heat exchange component exchange heat through the tube wall of the second tube of the second heat exchange component, gradually further heating up the normal temperature water or first-level preheated water in the first tube of the second heat exchange component, and at the same time further cooling down the hot water or first-level warm boiled water in the second tube of the second heat exchange component.

[0092] The tube wall of the second tube of the second heat exchange component should be made of a material that can transfer heat. In this embodiment, the second tube of the second heat exchange component is formed by a metal tube, that is, the tube wall of the second tube of the second heat exchange component is made of metal, and the internal space of the metal tube is the second tube of the second heat exchange component to ensure heat exchange efficiency.

[0093] In this embodiment, the first tube of the second heat exchange assembly and the second tube of the second heat exchange assembly are coaxially arranged to make the water flow space between the inner wall of the first tube of the second heat exchange assembly and the outer wall of the second tube of the second heat exchange assembly uniform.
