Description

Technical Field

[0001] The utility model relates to the technical field of water dispenser devices, in particular to a cooling box and a water dispenser that are easy to assemble. Background Art

[0002] Currently, to obtain drinking water at the right temperature, water dispensers typically mix 100°C hot water with 20°C purified or filtered water to create warm water between 100°C and 20°C. This warm water is not completely boiled, but rather a mixture of boiling water and purified or filtered water. Purified or filtered water can easily breed bacteria over time, making it unhygienic. Alternatively, a cooling box with hot and cold water convection heat exchange can be used to cool the hot water, but the cooling boxes currently available on the market have complex structures and a cumbersome assembly process.

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

[0022] Depend on Figures 1 to 4 As shown, an embodiment of the present invention provides a cooling box that is easy to assemble, including a box body 1 and an upper cover 2 and a lower cover 3 connected to both ends of the box body 1. There are multiple cavities 13 in the box body 1, and sealing members 4 are provided at both ends of the box body 1 for sealing the cavities 13. In this embodiment, the cavities 13 extend vertically and are arranged in parallel in the transverse direction; a hot water pipe 14 is provided in each cavity 13, and a cold water passage 15 is formed by the gap between the cavity wall of the cavity 13 and the pipe wall of the hot water pipe 14. The cold water passage 15 can be connected in sequence to form an S-shaped cold water channel, and the water inlet end of the S-shaped cold water channel is connected to the cold water inlet 11, and the water outlet end is connected to the cold water outlet 12; both ends of each hot water pipe 14 pass through the sealing members 4 respectively, and the hot water pipes 14 can be connected in sequence at the ends to form an S-shaped hot water channel, and the water inlet end of the S-shaped hot water channel is connected to the hot water inlet 21, and the water outlet end is connected to the hot water outlet 22. The seal 4 can separate the S-shaped cold water channel and the S-shaped hot water channel so that the water in the two channels does not contact each other. The seal 4 is preferably a silicone seal.

[0023] In the embodiment, the cooling box is assembled by the box body 1, the upper cover 2, the lower cover 3, the hot water pipes 14 and the sealing members 4. When assembling, the sealing members 4 are first installed on one side of the box body 1, then the hot water pipes 14 are inserted into the cavities 13, and then the sealing members on the other side of the box body 1 and the upper and lower covers are installed. The overall structure is simple and easy to assemble. The hot water pipes 14 are arranged in the cavities 13, the space between the cavity walls of the cavities 13 and the pipe walls of the hot water pipes 14 forms the cold water channels 15, and the two ends of the cavities 13 are sealed by the sealing members 4. The end portions of the plurality of hot water pipes 14 pass through the sealing members 4 and are sequentially connected to form an S-shaped hot water channel, and the plurality of cold water channels 15 form a cold water channel. The boiled hot water is introduced into the S-shaped hot water channel, and the 20℃ warm water is introduced into the S-shaped hot water channel. The sealing members 4 can prevent the hot and cold water from contacting each other. The hot water flows in the hot water pipes 14, and the warm water flows outside the hot water pipes 14, so that the hot water is cooled. The S-shaped water flow path can make the water flow in the cooling box in an S-shaped manner, prolong the flow time of the water flow, and fully cool the hot water, so that the straight drinking water between 20℃ and 100℃ is obtained.

[0024] Referring to Figure 1 The hot water inlet 21 is arranged at the top of the upper cover 2, and the hot water outlet 31 is arranged at the bottom of the lower cover 3. The cold water inlet 11 is arranged at the lower end of the box body 1, and the cold water outlet 12 is arranged at the upper end of the box body 1, so that the water flow directions of the S-shaped cold water channel and the S-shaped hot water channel are opposite, and the cold water and the hot water can fully convect to exchange heat.

[0025] Referring to Figure 2 and Figure 3 The first water passing cavity 22 is arranged in the upper cover 2, and the second water passing cavity 32 is arranged in the lower cover 3. The hot water pipes 14 are connected to the first water passing cavity and the second water passing cavity in a staggered manner, that is, the lower ends of the first and second hot water pipes 14 are connected through the second water passing cavity 32, the upper ends of the second and third hot water pipes 14 are connected through the first water passing cavity 22, and so on, so as to sequentially form an S-shaped hot water channel.

[0026] Referring to Figure 3 One end of the cavity wall between the two adjacent cavities 13 and the sealing member 4 on the same side form a water passing opening 16. The two adjacent water passing openings 16 are located at the upper and lower ends, respectively. The cold water channels 15 are connected through the water passing openings 16, that is, the water passing opening 16 between the first and second cavities 13 is at the upper end, the water passing opening 16 between the second and third cavities 13 is at the lower end, and so on, so as to sequentially form an S-shaped cold water channel. It can be understood that a through hole can also be arranged on the cavity wall to connect the cold water channels 15.

[0027] In another embodiment, a plurality of rows of cavities 13 are provided in the box 1, each row of cavities 13 being capable of forming an S-shaped cold water channel and an S-shaped hot water channel, the S-shaped cold water channels of adjacent two rows being connected end to end, and the S-shaped hot water channels of adjacent two rows being connected end to end. By providing the plurality of rows of cavities 13, the water flow route can be sufficiently extended, so that the cooling box with a smaller volume can load a longer water flow route, and the hot water can be sufficiently cooled. In the present application, three rows of cavities 13 are provided, and the cooling box with a size of 100mm*29mm*164mm can load a hot water passing pipe 14 with a length of 4.6 meters, so that the hot water is completely cooled, and the upper and lower structures are better assembled. The hot water passing pipe 14 is made of stainless steel pipe.

For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
