[0003] The efficiency and quality of a water dispenser's constant-temperature water output are closely related to its heat exchange structure. Currently, the heat exchange structure design incorporates multiple overlapping cold and hot water layers within the dispenser.

The efficiency and quality of the heat exchange structure are limited by the contact between the hot and cold water layers. In this overlapping design, the contact area between the hot and cold water layers is flat, which is limited, resulting in low efficiency in heating the cold water and cooling the hot water.

[0027] In order to help those skilled in the art better understand the present invention, the following will provide a clear and complete description of the technical solutions of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0028] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0029] Example 1:

[0030] Figure 1 This is a schematic diagram of a heat exchange structure provided in Example 1. This embodiment can be applied to increase the contact area between the cold water component and the hot water component, improve the heat exchange efficiency and quality, etc. Figure 1 The heat exchange structure specifically includes: a first heat exchange layer 101 and a second heat exchange layer 102 that are fixedly connected, the first heat exchange layer 101 being provided with at least two first hot water channels 1012 and at least two first cold water channels 1011, and the second heat exchange layer 102 being provided with at least two second hot water channels 1022 and at least two second cold water channels 1021; wherein, at least two first hot water channels 1012 and at least two first cold water channels 1011 are alternately arranged in the first heat exchange layer 101, and at least two second hot water channels 1022 and at least two second cold water channels 1021 are alternately arranged in the second heat exchange layer 102, and the hot and cold water channels of the first heat exchange layer 101 and the second heat exchange layer 102 have different deployment rules.

[0031] Among them, the hot water channel can be understood as a water pipe that transmits hot water, the cold water channel can be understood as a water pipe that transmits cold water, the hot and cold water channel deployment rules can be understood as the arrangement of the hot and cold water channels, and the different hot and cold water channel deployment rules of the first heat exchange layer and the second heat exchange layer can be understood as the arrangement of the hot and cold water channels of the first heat exchange layer and the second heat exchange layer is opposite. For example, when the arrangement of the hot and cold water channels of the first heat exchange layer is that the cold water channels and the hot water channels are arranged alternately in sequence, the arrangement of the hot and cold water channels of the second heat exchange layer is that the hot water channels and the cold water channels are arranged alternately in sequence, when the arrangement of the hot and cold water channels of the first heat exchange layer is that the hot water channels and the cold water channels are arranged alternately in sequence, the arrangement of the hot and cold water channels of the second heat exchange layer is that the cold water channels and the hot water channels are arranged alternately in sequence.

[0032] The advantage of this arrangement is that the hot water channel can be spread around the cold water channel, and the cold water channel can be spread around the hot water channel, for example, Figure 1Any channel that a cold water channel contacts is a hot water channel, and any channel that a hot water channel contacts is a cold water channel, thereby increasing the contact area between the cold water channel and the hot water channel and improving the heat exchange capacity of the heat exchange structure.

[0033] It is worth noting that the symbols in the figure are used to distinguish cold water channels from hot water channels, and do not represent the shapes of cold water channels and hot water channels. Figure 1 The rectangular pipe corresponding to the square in the middle is the cold water pipe, and the rectangular pipe corresponding to the circle is the hot water pipe. Specifically, the rectangular pipe corresponding to the solid square is the second cold water pipe, the rectangular pipe corresponding to the hollow square is the first cold water pipe, the rectangular pipe corresponding to the solid circle is the second hot water pipe, and the rectangular pipe corresponding to the hollow circle is the first hot water pipe.

[0034] The heat exchange structure of the present invention is symmetrical along the contact surface between the first heat exchange layer and the second heat exchange layer. The channels are of the same size. The sum of the number of first hot water channels and the number of first cold water channels is the same as the sum of the number of second hot water channels and the number of second cold water channels. That is, the total number of channels in the first heat exchange layer is the same as the total number of channels in the second heat exchange layer. The absolute value of the difference between the number of first hot water channels and the number of first cold water channels is an integer not greater than 1, and the absolute value of the difference between the number of second hot water channels and the number of second cold water channels is an integer not greater than 1.

[0035] For example, when the number of channels of the first cold water channel is 5, the number of channels of the first hot water channel is 4, 5 or 6, and the number of channels of the second hot water channel is related to the number of channels of the first heat exchange layer. If the number of channels of the first heat exchange layer is 9, the number of channels of the second hot water channel is 4; if the number of channels of the first heat exchange layer is 11, the number of channels of the second hot water channel is 6; if the number of channels of the first heat exchange layer is 10, the number of channels of the second hot water channel is 5. Specifically, when the number of channels of the first hot water channel and the first cold water channel is both 5, if the hot and cold water channel deployment rule of the first heat exchange layer is that the hot water channel and the cold water channel are arranged alternately in sequence, then the first channel of the first heat exchange layer is the first first hot water channel, and the last channel is the fifth first cold water channel; if the hot and cold water channel deployment rule of the first heat exchange layer is that the cold water channel and the hot water channel are arranged alternately in sequence, then the first channel of the first heat exchange layer is the first first cold water channel, and the last channel is the fifth first hot water channel.

[0036] The method for determining the number of channels and the arrangement method of the second heat exchange layer are the same as those of the first heat exchange layer, and will not be elaborated in this embodiment.

[0037] The first heat exchange layer is also provided with a first water inlet and a first water outlet, and the second heat exchange layer is also provided with a second water inlet and a second water outlet. The first water inlet and the second water inlet are arranged on the same side of the heat exchange structure, and the first water outlet and the second water outlet are arranged on the same side of the heat exchange structure; the first water inlet is connected to the water inlet end of the first channel of the first heat exchange layer, and the second water inlet is connected to the water inlet end of the first channel of the second heat exchange layer; the first water outlet is connected to the water outlet end of the last channel of the first heat exchange layer, and the second water outlet is connected to the water outlet end of the last channel of the second heat exchange layer.

[0038] Among them, the first water inlet can be understood as the water inlet deployed on the first heat exchange layer, the first water outlet can be understood as the water outlet deployed on the first heat exchange layer, the second water inlet can be understood as the water inlet deployed on the second heat exchange layer, and the second water outlet can be understood as the water outlet deployed on the second heat exchange layer. The first water inlet and the second water inlet are respectively connected to the first channel of the first heat exchange layer and the second heat exchange layer. When the first water inlet is connected to the cold water channel, the second water inlet is connected to the hot water channel. When the first water inlet is connected to the hot water channel, the second water inlet is connected to the cold water channel. When the hot water in the hot water channel is transferred from the water inlet to the water outlet, the heat will be continuously exchanged for the cold water in the cold water channel, thereby increasing the temperature of the cold water in the cold water channel and reducing the temperature of the hot water in the hot water channel.

[0039] The first water inlet and the second water inlet are arranged on the same side of the heat exchange structure, and the first water outlet and the second water outlet are arranged on the same side of the heat exchange structure, and the water outlet and the water inlet are arranged on both sides relatively. The advantage of this arrangement is that the cold water with the lowest temperature in the cold water channel (generally the cold water that has just flowed into the heat exchange structure) and the hot water with the highest temperature in the hot water channel (generally the hot water that has just flowed into the heat exchange structure) can directly contact each other, and continue to exchange heat, thereby improving the heat exchange efficiency and quality.

[0040] The water inlet is connected to the first channel of the heat exchange layer. When the channel deployment rule of the first heat exchange layer is that the hot and cold channels alternate in sequence, and the channel deployment rule of the second heat exchange layer is that the hot and cold channels alternate in sequence, the first water inlet is connected to the water inlet end of the first cold water channel, and the second water inlet is connected to the water inlet end of the first second hot water channel; when the channel deployment rule of the first heat exchange layer is that the hot and cold channels alternate in sequence, and the channel deployment rule of the second heat exchange layer is that the hot and cold channels alternate in sequence, the first water inlet is connected to the water inlet end of the first hot water channel, and the second water inlet is connected to the water inlet end of the first second cold water channel.

[0041] The water flow within the heat exchange structure is as follows: water from the first water inlet flows through the first channel of the first heat exchange layer, the second channel of the second heat exchange layer, the third channel of the first heat exchange layer, the fourth channel of the second heat exchange layer, and so on, sequentially passing through the odd-numbered channels of the first heat exchange layer and the even-numbered channels of the second heat exchange layer, and then flows out through the outlet connected to the odd-numbered channels of the first heat exchange layer or the outlet connected to the even-numbered channels of the second heat exchange layer. Similarly, water from the second water inlet flows through the first channel of the second heat exchange layer, the second channel of the first heat exchange layer, the third channel of the second heat exchange layer, the fourth channel of the first heat exchange layer, and so on, sequentially passing through the odd-numbered channels of the second heat exchange layer and the even-numbered channels of the first heat exchange layer, and then flows out through the outlet connected to the odd-numbered channels of the second heat exchange layer or the outlet connected to the even-numbered channels of the first heat exchange layer.

[0042] Figure 2 This is a side structural diagram of a heat exchange structure provided in Example 1. Figure 3 This is a side structural diagram of another heat exchange structure provided in Example 1. Figure 4 This is a schematic diagram of a water flow mode provided in Example 1. Figure 2 and Figure 3 There are two opposite side views. The direction of the arrow in the figure indicates the direction of water transmission. The solid line pipe in the figure indicates the water pipe on the visible side, and the dotted line pipe indicates the water pipe on the opposite side of the visible side. The circular hole on the top surface indicates the water inlet. Figure 2 、 Figure 3 and Figure 4 It can be seen that the water is transported across the heat exchange layer and the channel. Figure 4 This is the transmission diagram of cold water. It can be seen that the cold water is transmitted through the odd-numbered channels of the first heat exchange layer and the even-numbered channels of the second heat exchange layer in sequence, and flows out from the outlet connected by the even-numbered channels of the second heat exchange layer.

[0043] When the first water inlet is connected to the water inlet end of the first first cold water channel and the second water inlet is connected to the water inlet end of the first second hot water channel, the ath second cold water channel is respectively connected to the a-1th first cold water channel and the first candidate cold water unit, the first candidate cold water unit is the a+1th first cold water channel or the second water outlet, the bth first hot water channel is respectively connected to the b-1th second hot water channel and the first candidate hot water unit, and the first candidate hot water unit is the b+1th second hot water channel or the first water outlet; wherein, a and b are integers, 2≤a≤N1, 2≤b≤N2, N1 is the total number of cold water channels of the second heat exchange layer, and N2 is the total number of hot water channels of the first heat exchange layer.

[0044] Exemplarily, whether the first candidate cold water unit is the a+1th first cold water channel or the second water outlet depends on the number of cold water channels in the first heat exchange layer and the number of cold water channels in the second heat exchange layer. When the number of cold water channels in the first heat exchange layer is N1+1, the first candidate cold water unit is the a+1th first cold water channel. When the number of cold water channels in the first heat exchange layer is N1, the first candidate cold water unit is the second water outlet. Whether the first candidate hot water unit is the b+1th second hot water channel or the first water outlet depends on the number of hot water channels in the first heat exchange layer and the number of hot water channels in the second heat exchange layer. When the number of hot water channels in the second heat exchange layer is N2+1, the first candidate hot water unit is the b+1th second hot water channel. When the number of hot water channels in the second heat exchange layer is N2, the first candidate hot water unit is the first water outlet.

[0045] Similarly, when the first water inlet is connected to the water inlet end of the first first hot water channel and the second water inlet is connected to the water inlet end of the first second cold water channel, the cth second hot water channel is respectively connected to the c-1th first hot water channel and the second candidate hot water unit, the second candidate hot water unit is the c+1th first hot water channel or the second water outlet, the dth first cold water channel is respectively connected to the d-1th second cold water channel and the second candidate cold water unit, and the second candidate cold water unit is the d+1th second cold water channel or the first water outlet; wherein, c and d are integers, 2≤c≤N3, 2≤d≤N4, N3 is the total number of hot water channels of the second heat exchange layer, and N4 is the total number of cold water channels of the first heat exchange layer.

[0046] When the sum of the number of channels of the first hot water channel and the number of channels of the first cold water channel is an odd number, the water entering the first water inlet flows out through the first water outlet, and the water entering the second water inlet flows out through the second water outlet; when the sum of the number of channels of the first hot water channel and the number of channels of the first cold water channel is an even number, the water entering the first water inlet flows out through the second water outlet, and the water entering the second water inlet flows out through the first water outlet.

[0047] For example, assuming the sum of the number of first hot water channels and the number of first cold water channels is 5, the first heat exchange layer includes, in sequence, the first first cold water channel, the first first hot water channel, the second first cold water channel, the second first hot water channel, and the third first cold water channel. The second heat exchange layer includes, in sequence, the first second hot water channel, the first second cold water channel, the second second hot water channel, the second second cold water channel, and the third second hot water channel. Cold water flowing into the first water inlet passes through the first first cold water channel, the first second cold water channel, the second first cold water channel, the second second cold water channel, and the third first cold water channel before flowing out of the first water outlet. Hot water flowing into the second water inlet passes through the first second hot water channel, the first first hot water channel, the second second hot water channel, the second first hot water channel, and the third second hot water channel before flowing out of the second water outlet.

[0048] The technical solution of this embodiment utilizes a double-layered, cross-distributed pattern of hot and cold water channels. This design ensures that the hot water channel is surrounded by cold water channels, and vice versa. This effectively increases the contact area between the hot and cold channels, improving the heat exchange efficiency of the heat exchange structure. This solves the problem of the overlapped design, where the contact area between the hot and cold water layers is limited to a flat surface, resulting in low efficiency in heating up the cold water and cooling down the hot water.

[0049] Example 2:

[0050] The present invention also provides a heat exchange device. This embodiment can be used to increase the contact area between cold water components and hot water components, improve heat exchange efficiency and quality, etc. The heat exchange device specifically includes: i heat exchange structures of any one of the above embodiments, where i is a positive integer.

[0051] Figure 5 This is a structural diagram of a heat exchange device provided in Example 2. Figure 5 It includes two heat exchange structures. The red circle and black circle in the figure represent two channels respectively. For example, the red circle represents the hot water channel, the black circle represents the cold water channel, the red circle at the top represents the hot water outlet, and the black dotted line connecting the two red circles represents the connecting pipe of the two heat exchange structures.

[0052] The heat exchange structures are generally stacked and connected, and the first heat exchange layer of the jth heat exchange structure is fixedly connected to the second heat exchange layer of the j-1th heat exchange structure, where j is an integer, 2≤j≤i.

[0053] Specifically, the water inlet of the j-th heat exchange structure and the water outlet of the j-1-th heat exchange structure are deployed on the same side of the heat exchange equipment; wherein, the first water inlet of the j-th heat exchange structure is connected to the first water outlet of the j-1-th heat exchange structure, and the second water inlet of the j-th heat exchange structure is connected to the second water outlet of the j-1-th heat exchange structure.

[0054] The heat exchange device in this embodiment includes any of the heat exchange structures described in the above embodiments. This improves heat exchange efficiency and quality. It addresses the issues of the overlapping design, where the contact area between the cold and hot water layers is limited, resulting in low efficiency in heating cold water and cooling hot water. Furthermore, the heat exchange device provided in this embodiment includes the heat exchange structure described in the above embodiments and exhibits the corresponding beneficial effects of the aforementioned heat exchange structures.

[0055] Example 3:

[0056] The present invention further provides a water dispenser, which can be applied to increase the contact area between the cold water component and the hot water component, improve the heat exchange efficiency and quality, etc. The water dispenser includes any one of the heat exchange devices in the above embodiments.

[0057] The heat exchange work of the hot and cold water of the water dispenser can be performed using the above-mentioned heat exchange equipment. The advantage of such a setting is that it can effectively reduce the temperature of the hot water output by the water dispenser and increase the temperature of the cold water output.

[0058] The water dispenser in this embodiment includes any of the heat exchange devices in the above embodiments. It exhibits the corresponding beneficial effects of the above heat exchange devices. It solves the problems of the overlapping design, where the contact area between the cold and hot water layers is limited to a flat surface, resulting in low efficiency in heating cold water and cooling hot water.
