Description

Technical Field

[0001] The utility model relates to a liquid distributing device. Background Art

[0002] A liquid distributor is a device used to distribute liquid evenly. There are various liquid distributors with different structures in the prior art, such as the "Liquid Distributor Device" disclosed in the Chinese Utility Model Patent No. 201320500874.4 (Authorization Announcement No. CN 203494521 U). The liquid distributor device consists of an upper liquid distribution pan, a middle liquid distribution pan, a lower liquid distribution pan, a connecting plate, a distribution pipe and a distribution hole. The upper liquid distribution pan, the middle liquid distribution pan and the lower liquid distribution pan are all disc-shaped structures, and evenly distributed distribution holes are provided on the bottom of the pan. The upper liquid distribution pan, the middle liquid distribution pan and the lower liquid distribution pan are arranged in three layers in sequence: upper, middle and lower. They are connected by connecting plates on all sides, and distribution pipes are connected to the distribution holes of the lower liquid distribution pan. The distribution pipes are all exposed through the distribution holes and the exposed heights of the distribution pipes are the same. Since the exposed heights of the pipe heads of the distribution pipes connected to the various distribution holes of the liquid distribution pan are the same, the liquid flowing into the distribution pipes through the pipe mouths is uniform.

[0003] Furthermore, to improve cooking comfort, refrigerated range hoods were invented, and liquid distributors were installed on these hoods. When cooling mode is enabled, condensed water on the evaporator surface is collected and pumped to the liquid distributor via a water pump. From there, it flows through the distributor's outlet onto the condenser. This condensed water cools the condenser, improving its heat exchange efficiency and, consequently, air conditioning performance. However, existing liquid distributors only distribute the condensed water on the condenser, effectively consuming it and preventing it from being drained away. Utility Model Content

[0004] The first technical problem to be solved by the present invention is to provide a liquid distribution device that can realize both self-consumption and external discharge of condensed water in response to the above-mentioned existing technical status.

[0005] The technical solution adopted by the present invention to solve the above technical problems is: a liquid distribution device, including a base and an upper cover installed on the base, the base and the upper cover together enclose a liquid distribution cavity, and the characteristic is that: a first water receiving port, a second water receiving port and a water outlet are provided on the base, the first water receiving port is connected to the water outlet through the liquid distribution cavity, the port of the first water receiving port is used to connect to the internal circulation water inlet pipe, the second water receiving port is independent of the first water receiving port, the water inlet end of the second water receiving port is used to connect to the external water inlet pipe, and the water outlet end of the second water receiving port is used to connect to the external water outlet pipe.

[0006] In order to distribute the liquid evenly, the base and the upper cover are both in the shape of long strips, and the water outlets are arranged at the bottom of the base and are spaced apart along the length direction of the base.

[0007] In order to distribute the liquid more evenly, the water outlet on the left side of the base and the water outlet on the right side of the base are both arranged tilted from the inside of the base to the outside of the base.

[0008] In order to prevent uneven water distribution due to tilted installation of the liquid distribution device, the inner bottom surface of the base is tilted downward from both ends to the middle.

[0009] Further preferably, the inclination angle A of the inner bottom surface of the base relative to the horizontal satisfies 175°≤A<180°.

[0010] The first water receiving port can be installed at a plurality of different positions of the liquid distributing device. Preferably, the first water receiving port is arranged at an end portion in the length direction of the base.

[0011] The second water inlet can be installed at a plurality of different positions. Preferably, the second water inlet is arranged adjacent to the first water inlet.

[0012] There may be a variety of detachable connection structures between the base and the upper cover. Preferably, the upper cover is detachably connected to the base via a snap-fit ​​structure, which is provided on both sides of the base and the upper cover in the width direction and spaced apart along the length direction.

The claw extends into the water outlet end of the interface body from top to bottom and is upside down on the clamping cap. The clamping ring is provided at the top of the clamping cap and is clamped between the claw and the cap. The sealing ring is installed inside the interface body and is located below the claw.

[0015] Compared with the prior art, the advantages of the present invention are that the liquid distribution device is provided with a first water inlet, a second water inlet and a water outlet on the base, and the first water inlet is connected to the water outlet, that is, the first water inlet serves as an internal circulation consumption interface for connecting the internal circulation water inlet pipe, and the second water inlet is an external discharge interface for connecting the external discharge water inlet pipe and the external discharge pipe. When the refrigeration system is working, the condensed water enters the liquid distribution cavity through the first water inlet and is evenly distributed through the water outlet. When the use environment is in a high humidity condition, the internal circulation of the condensed water may not be sufficient for complete consumption. At this time, the water pipe can be connected to the external discharge interface to discharge the condensed water. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0025] like Figures 1 to 5 As shown, the liquid dispenser of this embodiment includes a base 1 and an upper cover 2. Both the base 1 and the upper cover 2 are in the shape of a long strip. The base 1 and the upper cover 2 adopt a detachable connection structure. In this embodiment, the base 1 and the upper cover 2 are detachably connected using a snap-fit ​​structure 10. The snap-fit ​​structure 10 is provided on both sides of the width direction of the base 1 and the upper cover 2 and is spaced apart along the length direction. The installation is convenient and the connection is relatively firm. In addition to the snap-fit ​​structure 10, Figure 1 In addition to the structure, you can also use Figure 8 The structure shown in FIG. 1 is a conventional buckle structure 10 and will not be described in detail.

[0026] The base 1 and the upper cover 2 are together enclosed to form a liquid distribution cavity 3, and a water outlet 6 is provided on the bottom of the base 1, i.e., the liquid distribution cavity 3. In order to ensure uniform water discharge, there are 5 water outlets 6 in this embodiment and they are spaced apart along the length direction of the base 1, and the water outlet 6 on the left side of the base 1 and the water outlet 6 on the right side of the base 1 are both arranged tilted from the inside of the base 1 to the outside of the base 1, that is, the water outlet 6 extends outward. In addition, the inner bottom surface of the base 1 is tilted downward from both ends to the middle. In this embodiment, the inclination angle A of the inner bottom surface of the base 1 relative to the horizontal satisfies 175°≤A<180°. After adopting this inclination angle, the phenomenon of uneven water distribution caused by the tilted installation of the liquid distribution device can be prevented.

[0027] The base 1 is provided with a first water inlet 4 and a second water inlet 5 which are independent of each other. In this embodiment, the first water inlet 4 is arranged at the end of the base 1 in the length direction, and the second water inlet 5 is arranged adjacent to the outside of the first water inlet 4. The first water inlet 4 is connected to the water outlet 6 through the liquid distribution cavity 3, and the port of the first water inlet 4 is used to connect the inner circulation water inlet pipe 7. The water inlet end of the second water inlet 5 is used to connect the outer discharge water inlet pipe 8, and the water outlet end of the second water inlet 5 is used to connect the outer discharge water outlet pipe 9. The second water inlet 5 includes a connector body 51, a clamping jaw 52, a clamping ring 53, a clamping cap 54 and a sealing ring 55. The connector body 51 has a vertical water flow passage inside. The clamping cap 54 is installed at the water outlet end of the connector body 51. The clamping jaw 52 extends into the water outlet end of the connector body 51 from top to bottom and is inverted on the clamping cap 54. The clamping jaw 52 is arranged at the top of the clamping cap 54 and is clamped between the clamping jaw 52 and the clamping cap 54. The sealing ring 55 is installed inside the connector body 51 and below the clamping jaw 52.

[0028] As shown in Figure 6 and Figure 7 , the liquid distribution device is installed on the condenser 100 through the clamping part 11 at the bottom of the base 1. When working, the condensed water flowing out of the water outlet 6 of the liquid distribution device is uniformly distributed on the surface of the condenser 100 and flows down along the wavy line shown on the surface of the condenser 100 as shown in Figure 7 .

[0029] The liquid distribution device is applied in a refrigeration system. During the operation of the refrigeration system, the condensed water generated by the evaporator flows into the water box. The water pump pumps the accumulated condensed water to the liquid distribution device above the condenser. The liquid distribution device releases the water pressure generated by the water pump and flows onto the fins of the condenser in a free-flowing state until the entire surface of the condenser is filled. Due to the high temperature of the condenser surface, a part of the condensed water will evaporate and can be discharged. The unspent condensed water flows back to the water box and is continuously pumped and circulated by the water pump. The finned condenser has strong water storage capacity and can allow the condensed water to stay on the surface for a long time and fully exchange heat with the condenser surface. When the use environment is in a high humidity working condition, the inner circulation of the condensed water may not be enough to completely consume, at which time the water pipe needs to be connected to the outer discharge interface, i.e. the second water inlet 5, to discharge the condensed water.
