Description

Technical Field

[0001] This utility model relates to the technical field of heat exchange devices for water dispensers, and more specifically, to a hot water temperature conversion device and a water dispenser. Background Technology

[0002] Water dispensers primarily employ two methods to cool boiling water to a drinkable temperature: 1. Mixing boiling water with low-temperature purified water to create warm water, or installing a heat exchanger. However, the resulting warm water is not fully boiled, and purified water is prone to bacterial growth if left for extended periods, making it less clean and hygienic. 2. Cooling the boiling water in the hot water pipes through a heat exchange chamber. For small household water dispensers, due to size limitations, a small-volume heat exchanger is required. However, the short path of the hot water pipe in a small-volume heat exchanger often leads to insufficient cooling, resulting in high outlet water temperatures that are not safe for direct consumption.

[0003] In view of this, the applicant hereby submits this application after studying the existing technology. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a hot water temperature conversion device, including a box body having a cold water inlet, a cold water outlet, a hot water inlet, and a hot water outlet, and end caps joined to both ends of the box body. A sealing element and a connecting element are provided between the box body and the end caps. The box body has a plurality of heat exchange chambers, and the two ends of the plurality of heat exchange chambers are respectively sealed by the sealing element. The heat exchange chambers are connected end to end to form a cold water flow channel. The cold water inlet and the cold water outlet are provided on the cold water flow channel.

[0006] The connector has a plurality of first connecting cavities on the side facing the seal. Each heat exchange cavity is provided with a hot water pipe. The two ends of the hot water pipes extend through the seal into the first connecting cavity. The ends of the hot water pipes are connected sequentially through the plurality of first connecting cavities to form a hot water flow channel.

[0007] As a further optimization, the cold water inlet, the cold water outlet, the hot water inlet, and the hot water outlet are respectively located on both sides of the same end of the box, and the water flow directions in the cold water channel and the hot water channel are opposite.

[0008] As a further optimization, the connector at the upper end of the box body is provided with two second connecting cavities on the side facing the seal. The hot water inlet and the hot water outlet are located at the top of the box body and are respectively connected to the hot water flow channel through the second connecting cavities.

[0009] As a further optimization, the heat exchange chamber is provided in two rows, and the two rows of heat exchange chambers are arranged alternately. The two rows of heat exchange chambers are connected alternately in sequence, and the hot water pipes are connected alternately in sequence through the first connecting chamber.

Hot water pipes are installed in the heat exchange chambers, and the two ends of the hot water pipes pass through sealing parts and are connected sequentially through the first connecting cavity on the connector to form a hot water flow channel. Boiled hot water flows inside the hot water pipes, while room temperature water flows on the outer wall of the hot water pipes, thereby cooling the boiled water so that the warm water that comes out is fully boiled. In addition, by setting up multiple rows of heat exchange chambers connected sequentially to form a cold water flow channel, cold water and hot water can respectively circulate in an S-shape within the box.

[0026] Example

[0027] Depend on Figures 1 to 6As shown, this utility model embodiment provides a hot water temperature conversion device, including a box body 1 with a cold water inlet 11, a cold water outlet 12, a hot water inlet 13, and a hot water outlet 14, and end caps 2 joined to both ends of the box body 1. A sealing element 3 and a connecting element 4 are provided between the box body 1 and the end caps 2. The two ends of the box body 1 are respectively sunken to form a cavity, and the sealing element 3 and the connecting element 4 are placed in the cavity. The sealing element 3 is located on the side closer to the box body. The box body 1 has a plurality of heat exchange chambers 5. The two ends of the heat exchange chambers 5 are connected by the sealing element to form a cold water flow channel. The inlet and outlet ends of the cold water flow channel are respectively connected to the cold water inlet 11 and the cold water outlet 12. The connecting element 4 is provided with a plurality of first connecting cavities 41 on the side facing the sealing element 3. Each heat exchange chamber 5 is provided with a hot water pipe 6. A gap is formed between the hot water pipe 6 and the cavity wall of the heat exchange chamber 5 to allow cold water to flow. The hot water pipe 6 extends through the sealing member 3 at both ends and into the first connecting cavity 41, and is connected in sequence through the first connecting cavity 41 to form a hot water flow channel. The inlet and outlet of the hot water flow channel are respectively connected to the hot water inlet 13 and the cold water outlet 14.

[0028] In this embodiment, a water path is formed by the heat exchange chamber, sealing element, and hot water pipe, preventing contact between hot and cold water. Hot water flows inside the hot water pipe, while cold water flows in the heat exchange chamber outside the hot water pipe. The hot and cold water circulate in an S-shape within the housing 1, thereby cooling the hot water with cold water to produce warm water that can be directly consumed. This ensures that the water dispenser can dispense fully boiled warm water, guaranteeing drinking water hygiene. The S-shaped circulating water path allows for a longer flow distance for a heat exchanger of the same volume, ensuring that the hot water is fully cooled. Furthermore, the hot water temperature conversion device of this application is connected to the hot water pipe 6 via the connector 4. The hot water pipe 6 is a straight pipe, making it easier to process. The sealing element 3 and the connector 4 are pressed onto the housing by the end cap 2. The end cap 2 and the housing 1 are detachably connected, making the heat exchange device easier to assemble and convenient for later disassembly and maintenance.

[0029] Specifically, the cold water inlet 11, the cold water outlet 12, the hot water inlet 13, and the hot water outlet 14 are respectively located on both sides of the same end of the housing 1. In this embodiment, all four water outlets are located at the upper end, with the hot water inlet and outlet above the cold water inlet and outlet. The connector 4 at the upper end of the housing 1 has two second connecting cavities 42 on the side facing the sealing member 3. The hot water inlet 13 and the hot water outlet 14 are respectively connected to the hot water flow channel through the second connecting cavities 42. Setting the water outlets at the same end facilitates a more reasonable layout of the water circuit inside the water dispenser. Preferably, the cold water inlet 11 and the hot water outlet 14 are on the same side, and the cold water outlet 12 and the hot water inlet 13 are on the same side, that is, the inlet and outlet ends of the cold water flow channel and the hot water flow channel are opposite, so that the water flow in the cold water flow channel and the hot water flow channel flows in opposite directions, and the cold and hot water convection improves the heat exchange effect.

[0030] Reference Figure 2 , Figure 4 and Figure 6 As shown, the heat exchange chambers 5 are arranged in two rows, and the two rows of heat exchange chambers 5 are staggered. A water passage groove 51 is provided at one end of the cavity wall of the two staggered heat exchange chambers 5. The water passage grooves 51 are staggered at the upper and lower ends, and the water passage grooves 51 and the sealing element 3 on the same side together form a water passage channel. The heat exchange chambers 5 are sequentially connected through the water passage channel. At the upper end of the cavity wall of the heat exchange chambers 5 at the very front and rear ends of the cold water flow channel, a water inlet is also provided for communication with the cold water inlet 11 and the cold water outlet 12. The first connecting cavity 41 on the connector 4 is arranged at an angle, with the upper and lower ends of the first connecting cavity 41 tilted in opposite directions, allowing the hot water pipes 6 to be sequentially connected through the first connecting cavity 41.

[0031] Reference Figure 1 The outer walls at both ends of the box body 1 are provided with first connecting holes 15, and the end cap 2 is provided with second connecting holes 21 that are adapted to the first connecting holes 15. The end cap 2 is detachably connected to both ends of the box body 1 by bolts engaging with the first connecting holes 15 and the second connecting holes 21, thereby pressing the connector and the seal onto the box body through the end cap 2. Preferably, the seal 3 can be a silicone seal, and the hot water pipe 6 is a stainless steel pipe.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
