Description

Technical Field

[0001] This invention relates to the field of drinking water equipment technology, specifically providing a heat exchanger and a boiled water dispenser including the heat exchanger. Background Technology

[0002] Existing boiled water dispensers typically use heat exchangers to cool hot water or heat cold water to achieve the purpose of preparing boiled water.

[0003] Currently, most heat exchangers on the market use corrugated sleeve or spiral tube structures. These heat exchangers have long, narrow, and complex flow channels, making them difficult to clean. When the water dispenser is idle or unused for extended periods, bacteria can easily grow and accumulate inside the heat exchange channels, reducing the quality and safety of the water, affecting the user's health, and resulting in a poor user experience.

[0004] Accordingly, there is a need in the field for a new type of heat exchanger to address the aforementioned problems. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problem, namely, to solve the problem that the heat exchange channels in existing heat exchangers are not easy to clean.

[0006] In a first aspect, the present invention provides a heat exchanger comprising an inlet, an outlet, a first pressure plate, a second pressure plate, and a flow channel assembly located between the first pressure plate and the second pressure plate, characterized in that the flow channel assembly comprises: a housing having flow channels formed therein; a partition located within the flow channels, the partition dividing the flow channels into a first flow channel and a second flow channel parallel to each other; wherein the inlet comprises a first inlet and a second inlet, the outlet comprises a first outlet and a second outlet, the two ends of the first flow channel are respectively connected to the first inlet and the first outlet, the two ends of the second flow channel are respectively connected to the second inlet and the second outlet, and the partition is detachably installed within the flow channels.

[0007] In the preferred embodiment of the heat exchanger described above, the separator includes a first insert plate, and a first slot is provided inside the housing. The first slot is formed on the inner bottom wall and / or inner side wall of the flow channel. The first insert plate is inserted into the first slot, and the first insert plate is arranged parallel to the flow channel along the length direction of the flow channel.

[0008] In the preferred embodiment of the heat exchanger described above, the separator includes a plurality of second insert plates and a plurality of adapter plates, wherein the plurality of second insert plates and the plurality of adapter plates are alternately connected in sequence, and the adapter plates are located at a curved position within the flow channel.

[0009] In the preferred embodiment of the heat exchanger described above, a second slot is formed on the side of the adapter plate, and the side end of the second insert plate is inserted into the second slot.

[0010] In the preferred embodiment of the heat exchanger described above, the flow channel assembly further includes clamping plates located on both sides of the separator to clamp and fix the separator.

[0011] In the preferred embodiment of the heat exchanger described above, a sealing strip is provided on the edge of the partition.

[0012] In the preferred embodiment of the heat exchanger described above, the shell structure is at least two sets of continuous U-shaped, S-shaped, or Z-shaped structures connected end to end.

[0013] In the preferred embodiment of the heat exchanger described above, the first inlet, the first outlet, the second inlet, and the second outlet are formed on the first pressure plate or the second pressure plate.

[0014] In the preferred embodiment of the heat exchanger described above, the first pressure plate or the second pressure plate is integrally formed with the shell structure.

[0015] In a second aspect, the present invention provides a boiled water dispenser, including the aforementioned heat exchanger.

[0016] Those skilled in the art will understand that the heat exchanger of the present invention includes an inlet, an outlet, a first pressure plate, a second pressure plate, and a flow channel assembly located between the first and second pressure plates. The flow channel assembly includes a housing and a partition. A flow channel is formed within the housing, and the partition is located within the flow channel, dividing the flow channel into a first flow channel and a second flow channel that run parallel to each other. The inlet includes a first inlet and a second inlet, and the outlet includes a first outlet and a second outlet. The two ends of the first flow channel are respectively connected to the first inlet and the first outlet, and the two ends of the second flow channel are respectively connected to the second inlet and the second outlet. The partition is detachably installed within the flow channel. With this configuration, when the first or second pressure plate on one side of the flow channel assembly is opened, the partition can be easily removed to clean and disinfect the flow channel within the housing, improving the convenience of cleaning the heat exchanger.

[0017] Furthermore, the separator includes a first insert plate, and the housing has a first slot formed on the inner bottom wall and / or inner side wall of the flow channel. The first insert plate is inserted into the first slot, and the first insert plate is arranged parallel to the flow channel along its length.

[0018] Furthermore, the separator includes multiple second insert plates and multiple adapter plates, which are sequentially and alternately connected, with the adapter plates located at curved positions within the flow channel. This arrangement, through the continuous splicing of multiple second insert plates and multiple adapter plates, effectively separates the complex flow channel structure, improving the compatibility between the separator and the complex flow channel.

[0019] Furthermore, the flow channel assembly also includes clamping plates located on both sides of the separator to hold and fix it in place. This arrangement further enhances the stability of the separator within the flow channel, preventing it from tilting or moving due to the pressure difference between the first and second flow channels, thus improving the safety of the heat exchanger.

[0020] Furthermore, a sealing strip is provided on the edge of the partition. With this arrangement, when the first or second pressure plate is closed on the housing, the sealing strip on the edge of the partition can prevent water leakage between the first and second flow channels, thus improving the sealing performance between the two flow channels.

[0021] Furthermore, the first inlet, first outlet, second inlet, and second outlet are formed on the first or second pressure plate. This arrangement facilitates connection with external piping and enhances the overall aesthetics of the heat exchanger.

[0022] Furthermore, the first or second pressure plate is integrated with the housing structure. This design simplifies the design and reduces manufacturing costs.

[0023] Furthermore, the boiled water dispenser provided by the present invention, based on the above technical solution, has the same technical effects as the heat exchanger because it uses the heat exchanger. Compared with existing boiled water dispensers, the boiled water dispenser of the present invention makes it easier to clean the heat exchanger and improves the user experience.

Therefore, it should not be construed as a limitation of this invention.

[0036] Furthermore, it should be noted that in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] Based on the problem pointed out in the background art that the flow channels in existing heat exchangers are difficult to clean, this invention provides a heat exchanger that, by arranging removable partitions within the heat exchange flow channels, facilitates the cleaning and disinfection of the flow channels, thereby improving the convenience of cleaning the heat exchanger.

[0038] Specifically, see Figures 1 to 7 The heat exchanger 1 of the present invention includes a first pressure plate 11, a second pressure plate 12, and a flow channel assembly located between the first pressure plate 11 and the second pressure plate 12. The flow channel assembly includes a housing 13 and a partition. More specifically, the first pressure plate 11 is located below the housing 13, and the second pressure plate 12 is located above the housing 13. The first pressure plate 11 and the second pressure plate 12 are fastened together by four bolts 16, clamping the housing 13 and the partition between the first pressure plate 11 and the second pressure plate 12. A heat exchange flow channel 131 is formed inside the housing 13. The partition is perpendicular to the inner bottom wall of the flow channel 131 and is detachably installed inside the flow channel 131, dividing the flow channel 131 into a first flow channel 1311 and a second flow channel 1312 that run parallel to each other. The heat exchanger 1 includes an inlet and an outlet. The inlet includes a first inlet 111 and a second inlet 112, and the outlet includes a first outlet 113 and a second outlet 114. The two ends of the first flow channel 1311 are connected to the first inlet 111 and the first outlet 113, respectively, and the two ends of the second flow channel 1312 are connected to the second inlet 112 and the second outlet 114, respectively.

[0039] With this setup, when cleaning the flow channel 131 inside the housing 13, it is only necessary to open the second pressure plate 12 on one side of the housing 13 and remove the partition from the flow channel 131. Users can easily and thoroughly clean and disinfect the flow channel 131 and the partition, which improves the convenience of cleaning the heat exchanger 1.

[0040] It should be noted that, in practical applications, those skilled in the art can set the separator as an integral plate structure or as a spliced ​​structure of multiple continuous plates, depending on the specific layout structure of the flow channel 131, as long as it is convenient for the separator to be detachably installed in the flow channel 131. Such adjustments and changes to the specific structure of the separator do not deviate from the principles and scope of the present invention and should be limited to the protection scope of the present invention.

[0041] The heat exchanger structure of the present invention will be described in detail below with reference to two embodiments.

[0042] Example 1

[0043] See Figure 1 , Figure 3 as well as Figure 4The heat exchanger 1 of this embodiment includes a first pressure plate 11, a second pressure plate 12, and a flow channel assembly located between the first pressure plate 11 and the second pressure plate 12. The flow channel assembly includes a housing 13 and a partition. The first pressure plate 11 and the second pressure plate 12 are fastened together by four bolts 16, clamping the housing 13 and the partition between them. The first pressure plate 11 and the housing 13 are integrally formed. The housing 13 is constructed with nine sets of continuously connected U-shaped structures, and the aforementioned U-shaped flow channels 131 are formed within the housing 13. A first slot 132 is provided within the housing 13, formed on the inner bottom wall and the inner side walls at both ends of the flow channel 131, and the first slot 132 is positioned along the centerline of the width of the flow channel 131. The separator includes a first insert plate 141, which is constructed in a U-shape to fit the U-shaped flow channel 131. That is, the first insert plate 141 is arranged parallel to the flow channel 131 along the length of the flow channel 131.

[0044] When the first insert plate 141 is vertically inserted into the first slot 132 within the flow channel 131, both the bottom edge and two side edges of the first insert plate 141 are inserted into the first slot 132, thereby achieving vertical insertion and fixation of the first insert plate 141 within the flow channel 131. The flow channel assembly also includes clamping plates located on both sides of the separator to hold and fix it. Specifically, the clamping plates include 18 first clamping plates 151 and 17 second clamping plates 152. First clamping plates 151 are provided at the straight positions of each U-shaped flow channel 131, and second clamping plates 152 are provided at the curved positions of each U-shaped flow channel 131. When the first insert plate 141 is inserted into the flow channel 131, the first clamping plates 151 and second clamping plates 152 respectively clamp and fix the first insert plate 141 from both sides, thereby ensuring the stability of the first insert plate 141 within the flow channel 131.

[0045] When the first insert plate 141 is securely inserted into the flow channel 131, the first insert plate 141 divides the flow channel 131 into a first flow channel 1311 and a second flow channel 1312 that run parallel to each other. The inlets include a first inlet 111 and a second inlet 112, and the outlets include a first outlet 113 and a second outlet 114. The two ends of the first flow channel 1311 are respectively connected to the first inlet 111 and the first outlet 113, and the two ends of the second flow channel 1312 are respectively connected to the second inlet 112 and the second outlet 114. Specifically, the first inlet 111 and the first outlet 113 are located at one end of the flow channel 131, and the second inlet 112 or the second outlet 114 is located at the other end of the flow channel 131. The first inlet 111, the first outlet 113, the second inlet 112, and the second outlet 114 are all formed on the first pressure plate 11.

[0046] The first insert plate 141 is made of stainless steel. A sealing strip made of silicone material is installed on the upper edge of the first insert plate 141. When the second pressure plate 12 is placed on the housing 13, the sealing strip on the first insert plate 141 is tightly pressed against the second pressure plate 12, thereby isolating the first flow channel 1311 and the second flow channel 1312 on both sides of the first insert plate 141 from each other and preventing leakage, thus improving the sealing performance between the first flow channel 1311 and the second flow channel 1312.

[0047] Example 2

[0048] See Figure 2 , Figure 3 , Figure 5 as well as Figure 6 The heat exchanger 1 of this embodiment includes a first pressure plate 11, a second pressure plate 12, and a flow channel assembly located between the first pressure plate 11 and the second pressure plate 12. The flow channel assembly includes a housing 13 and a partition. The first pressure plate 11 and the second pressure plate 12 are fastened together by four bolts 16, clamping the housing 13 and the partition between them. The first pressure plate 11 and the housing 13 are integrally formed. The housing 13 is constructed with nine sets of continuously connected U-shaped structures, and the aforementioned U-shaped flow channels 131 are formed within the housing 13. A first slot 132 is provided within the housing 13, formed on the inner bottom wall and the inner side walls at both ends of the flow channel 131, and the first slot 132 is positioned along the centerline of the width of the flow channel 131. The separator includes 18 second insert plates 142 and 17 adapter plates 143, which are alternately connected in sequence. Each adapter plate 143 is located at a bend within each set of U-shaped flow channels 131. Each adapter plate 143 has a second slot 1431 formed on both sides, and the side end of the second insert plate 142 is inserted into the second slot 1431.

[0049] When the second insert plate 142 located in the middle of the flow channel 131 is vertically inserted into the first slot 132 within the flow channel 131, the bottom edge of the second insert plate 142 is inserted into the first slot 132, and the two ends of the second insert plate 142 are respectively inserted into the corresponding second slots 1431 of the adapter plates 143 on both sides. Specifically, one side of the second insert plate 142 located at both ends of the flow channel 131 is inserted into the first slot 132 on the inner sidewall of the housing 13. Through this installation method, the second insert plate 142 is vertically inserted and fixed within the flow channel 131. The flow channel assembly also includes clamping plates located on both sides of the separator to clamp and fix the separator. Specifically, the clamping plates include 18 first clamping plates 151, with first clamping plates 151 provided in the straight position of each group of U-shaped flow channels 131. When the second insert plate 142 is inserted into the flow channel 131, the first clamping plate 151 clamps and fixes the second insert plate 142 from both sides, thereby ensuring the stability of the second insert plate 142 in the flow channel 131.

[0050] When the second insert plate 142 and the adapter plate 143 are sequentially inserted and assembled within the flow channel 131, the second insert plate 142 and the adapter plate 143 divide the flow channel 131 into a first flow channel 1311 and a second flow channel 1312 that run parallel to each other. The inlets include a first inlet 111 and a second inlet 112, and the outlets include a first outlet 113 and a second outlet 114. The two ends of the first flow channel 1311 are connected to the first inlet 111 and the first outlet 113, respectively, and the two ends of the second flow channel 1312 are connected to the second inlet 112 and the second outlet 114, respectively. Specifically, the first inlet 111 and the first outlet 113 are located at one end of the flow channel 131, and the second inlet 112 and the second outlet 114 are located at the other end of the flow channel 131. The first inlet 111, the first outlet 113, the second inlet 112, and the second outlet 114 are all formed on the first pressure plate 11.

[0051] Each second insert plate 142 is made of stainless steel, and a sealing strip (not shown in the figure) is installed at the upper edge of each second insert plate 142. The sealing strip is made of silicone material. When the second pressure plate 12 is placed on the housing 13, the sealing strip on each second insert plate 142 is tightly pressed against the second pressure plate 12, thereby isolating the first flow channel 1311 and the second flow channel 1312 on both sides of the second insert plate 142 and the adapter plate 143 from leakage, thus improving the sealing performance between the first flow channel 1311 and the second flow channel 1312.

[0052] It should be noted that the specific arrangement of the sealing strip in the above embodiments is not limited to the above situation. According to actual application, those skilled in the art can conveniently set the sealing strip around each insert plate, or set the sealing strip in the slot. Such adjustment and change of the specific setting position of the sealing strip does not deviate from the principle and scope of the present invention, and should be limited to the protection scope of the present invention.

[0053] Furthermore, the specific layout and quantity of the housing 13 in the above embodiments are not limited to the above settings. Depending on the actual application, those skilled in the art can set the shape of the housing 13 to an S-shaped structure, a Z-shaped structure, or other irregular structures. The quantity can be set to 7 or 10 groups, as long as the effect of increasing the length of the flow channel 131 can be achieved. Such adjustments and changes to the specific structure of the housing 13 do not deviate from the principle and scope of the present invention and should be limited to the protection scope of the present invention.

[0054] Furthermore, in the above embodiments, the housing 13 is not limited to being integrally constructed with the first pressure plate 11. Depending on the actual application, those skilled in the art can also construct the housing 13 and the second pressure plate 12 as an integral unit. Such adjustments and changes to the connection form between the housing 13 and the first pressure plate 11 or the second pressure plate 12 do not deviate from the principles and scope of the present invention and should be limited to the protection scope of the present invention.

[0055] It should also be noted that the arrangement of the first inlet 111, the first outlet 113, the second inlet 112, and the second outlet 114 is not limited to the above embodiments. Depending on the actual application, those skilled in the art can arrange the first inlet 111 and the first outlet 113 on the first pressure plate 11, and the second inlet 112 and the second outlet 114 on the second pressure plate 12; or, the first inlet 111 and the second inlet 112 on the first pressure plate 11, and the first outlet 113 and the second outlet 114 on the second pressure plate 12; or, all of the first inlet 111, the first outlet 113, the second inlet 112, and the second outlet 114 can be formed on either the first pressure plate 11 or the second pressure plate 12. Such adjustments and changes to the specific positions of the first inlet 111, the first outlet 113, the second inlet 112, and the second outlet 114 do not deviate from the principles and scope of the present invention and should be limited to the protection scope of the present invention. Of course, it is preferable that the first inlet 111, the first outlet 113, the second inlet 112, and the second outlet 114 are all formed on the first pressure plate 11.

[0056] Finally, the present invention also provides a boiled water dispenser that includes the heat exchanger 1 described above.

[0057] Specifically, see Figure 7The cooled boiled water dispenser of the present invention includes a heat exchanger 1, a water pump 2, a heating element 3, a faucet 4, a first regulating valve 51, and a second regulating valve 52. The water pump 2 draws raw water to the first inlet 111 of the heat exchanger 1. The first outlet 113 of the heat exchanger 1 is connected to the water inlet of the heating element 3. The water outlet of the heating element 3 is connected to the second inlet 112 of the heat exchanger 1. The second outlet 114 of the heat exchanger 1 outputs water to the faucet 4 via the second regulating valve 52. One end of the first regulating valve 51 is connected to the water outlet of the heating element 3, and the other end of the first regulating valve 51 is connected to the faucet 4.

[0058] When water pump 2 pumps cold water into the first flow channel 1311 through the first inlet 111, and then into the inlet of the heating element 3 through the first outlet 113, the heating element 3 heats the cold water from the first flow channel 1311 to boiling point and then into the second flow channel 1312 through the second inlet 112. The hot water in the second flow channel 1312 exchanges heat with the cold water in the first flow channel 1311 through a separator to form warm water, which is then discharged from the second outlet 114. When the first regulating valve 51 is closed and the second regulating valve 52 is opened, cooled boiled water after heat exchange can be supplied to the faucet 4. By opening and adjusting the opening of the first regulating valve 51 to control the flow rate of hot water through the first regulating valve 51, cooled boiled water at different temperatures can be output from the faucet 4.

[0059] It should be noted that the application of heat exchanger 1 is not limited to the specific structure of the above-mentioned boiled water dispenser. Depending on the actual application, heat exchanger 1 can also be used for heat exchange and temperature regulation in boiled water dispensers with different structures. Such use of heat exchanger 1 in different boiled water dispensers does not affect the deviation from the principle and scope of the present invention, and should be limited to the protection scope of the present invention.
