Description

Technical Field

[0001] This utility model belongs to the field of water purifiers, and in particular relates to a separate hot and cold water outlet. Background Technology

[0002] Existing water purifiers have a cooling module and a heating module, which are connected to a water outlet. Cold water and hot water can both come out of the water outlet according to the user's needs. However, since cold water and hot water share the same water outlet, temperature cross-contamination can occur. That is, if hot water comes out right after cold water comes out of the water outlet, it will affect the temperature of the hot water coming out of the water outlet.

[0003] Based on this, we have developed a separate hot and cold water tap to selectively dispense either cold or hot water according to different needs, without affecting each other. Utility Model Content

[0004] Purpose of the utility model: The technical problem to be solved by this utility model is to provide a separate hot and cold water outlet, so as to selectively dispense cold or hot water according to different needs, and prevent temperature cross-contamination between them.

[0005] Technical solution: The present invention provides a separate hot and cold water outlet, comprising a shell having a cold water chamber and a hot water chamber, and an end cap located at the top of the shell; the upper side of the hot water chamber is connected to the upper side of the cold water chamber to form a flow channel for steam to flow from the hot water chamber to the cold water chamber, and the end cap is provided with a cold water pipe extending into the cold water chamber.

[0006] Furthermore, the bottom of the housing of the separate hot and cold water outlet is provided with a cold water outlet and a hot water outlet, respectively. The side wall of the hot water chamber is provided with a hot water inlet. The cold water outlet is connected to the cold water chamber, and both the hot water inlet and the hot water outlet are connected to the hot water chamber.

[0007] Furthermore, the cold water pipe of the separate hot and cold water outlet extends into the cold water cavity and protrudes through the cold water outlet.

[0008] Furthermore, the end cap of the separate hot and cold water outlet is equipped with a baffle plate on the side of the steam flow channel. The baffle plate extends into the hot water chamber to prevent hot water entering from the hot water inlet from splashing into the steam flow channel after impacting the inner wall of the shell. The baffle plate is located at the upper end of the hot water inlet.

[0009] Furthermore, the cold water pipe of the separate hot and cold water outlet is located in the cold water cavity and forms a gap with the cold water cavity so that the gap becomes a flow channel for steam.

[0010] Furthermore, the hot water outlet of this separate hot and cold water faucet is equipped with a baffle to ensure that the water flows out in a balanced and uniform manner.

[0011] Furthermore, the number of baffles in this separate hot and cold water outlet is set to 3n, where n is a natural number, and they are evenly distributed along the circumference of the hot water outlet.

[0012] Furthermore, one end of the baffle of the separate hot and cold water outlet is located on the inner wall of the hot water outlet, and the other end is set towards the center of the hot water outlet to form an intermediate water flow channel.

[0013] Beneficial effects: Compared with the prior art, the advantages of this utility model are: the separate hot and cold water outlet divides the shell into two independent parts with a cold water chamber and a hot water chamber, so as to selectively dispense cold water or hot water according to needs, avoiding temperature cross-contamination between hot and cold water caused by using the same outlet; at the same time, a steam flow channel is formed at the upper end of the two chambers, so that steam can be discharged from the hot water chamber, improving the stability of the hot water outlet flow and avoiding splashing and scalding.

[0017] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings.

[0018] like Figure 1 and Figure 2As shown, the present invention discloses a separate hot and cold water outlet, comprising a housing 3 and an end cap 4 at the top of the housing 3. The bottom of the housing 3 is provided with a cold water outlet 7 and a hot water outlet 8, and a hot water inlet 9 is provided on the side wall of the housing 3. A cold water pipe 6 is provided on the end cap 4, extending into the housing 3. The hot water outlet 8 is provided with 3n (n is a natural number) baffles 11, which are evenly distributed around the circumference of the outlet. The specific number of baffles 11 can be flexibly set according to the actual size of the outlet, and the present invention does not impose a specific limitation. One end of each baffle 11 is located on the inner side wall of the hot water outlet 8, and the other end faces the center of the hot water outlet 8, forming a central water flow channel. This ensures a stable and uniform flow of water at the hot water outlet 8 regardless of the water flow rate, preventing splashing. When the water flow velocity is high, the specific surface area of ​​the hot water outlet 8 in contact with the water flow can be increased, thereby increasing the friction force of the water flow, increasing the viscosity force of the water flow, and reducing the Reynolds number of the water flow, so that the water flow is out in a laminar state, achieving a stable and uniform flow mode. When the water flow velocity is low, due to the concentrating effect of the baffle 11, the water flow can be concentrated and flow out from the middle channel formed by the baffle 11, avoiding dispersion, and also achieving a stable and uniform flow mode, preventing water splashing.

[0019] like Figure 3 As shown, the housing 3 is divided into two independent cavities: a cold water cavity 1 and a hot water cavity 2. The bottom end of the cold water cavity 1 is connected to the cold water outlet 7. The cold water pipe 6 is located inside the cold water cavity 1, and there is a certain gap between it and the inner wall of the cold water cavity 1. The hot water inlet 9 and the hot water outlet 7 are connected to the hot water cavity 2. The upper end of the hot water cavity 2 is connected to the upper end of the cold water cavity 1, thereby forming a flow channel 5 for steam to rise from the hot water cavity 2 and flow into the cold water cavity 1. Based on the gap between the flow channel 5 and the cold water pipe 6 on the side wall of the cold water cavity 1, a steam flow path is formed. If necessary, the steam can be discharged through the cold water outlet 7, further improving the stability of the water flow at the hot water outlet 8 and avoiding splashing and scalding. Preferably, the hot water cavity 2 and the cold water cavity 1 can share the same side wall. When there is a certain gap between the side wall and the end cap 4, a steam flow path 5 can be formed.

[0020] In addition to the cold water pipe 6, the end cap 4 is also equipped with a baffle plate 10. The baffle plate 10 is located on one side of the steam flow channel 5 and above the hot water inlet 9. The baffle plate 10 extends into the hot water chamber 2 to prevent hot water entering from the hot water inlet 9 from splashing into the steam flow channel 5 after impacting the inner wall of the shell 3.

[0021] The present invention's separate hot and cold water outlet divides the shell into two independent parts: a cold water chamber 1 and a hot water chamber 2. This allows for selective dispensing of either cold or hot water as needed, avoiding temperature fluctuations between the hot and cold water caused by using the same outlet. Furthermore, a steam flow channel 5 is formed at the upper end of both chambers, allowing steam to be discharged from the hot water chamber 2. This improves the stability of the water flow at the hot water outlet 8 and prevents splashing and scalding.
