Description

Technical Field

[0001] The utility model relates to a liquid distribution structure, in particular to a drainage liquid distribution joint and a condenser for installing the joint. Background Art

[0002] A liquid distributor is a device used to evenly distribute liquid. 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 tray, a middle liquid distribution tray, a lower liquid distribution tray, a connecting plate, a distribution pipe and a distribution hole. The upper liquid distribution tray, the middle liquid distribution tray and the lower liquid distribution tray are all disc-shaped structures, and evenly distributed distribution holes are provided on the bottom of the trays. The upper liquid distribution tray, the middle liquid distribution tray and the lower liquid distribution tray are arranged in three layers in sequence: upper, middle and lower, and are connected by connecting plates on all sides. Distribution pipes are connected to the distribution holes of the lower liquid distribution tray. Another example is the "Liquid distributor, heat exchanger and air-conditioning unit" disclosed in the Chinese invention patent application with application number 201810879931.1 (application publication number CN108917232 A). The liquid distributor includes an upper sealing plate and a lower shell. The upper sealing plate is arranged on the upper part of the lower shell and together with the lower shell, it encloses a liquid distribution cavity, and the edge of the lower shell is bent toward the outside of the liquid distribution cavity to form a first bending portion, and the first bending portion is riveted to the upper sealing plate. The liquid distributor, heat exchanger and air-conditioning unit provided by the invention can increase the assembly efficiency and assembly accuracy by riveting the upper sealing plate and the lower shell, and effectively prevent the welding deformation of the liquid distributor. In addition, the first liquid equalizing plate and the second liquid equalizing plate are arranged to equalize the liquid in the liquid distributor three times, which can ensure that the refrigerant entering the liquid distributor is evenly distributed in the axial and radial directions, thereby ensuring the liquid distribution effect of the liquid distributor. Although the above-mentioned liquid distributor can also achieve a good diversion effect, its structure is relatively complex.

[0003] In addition, in order to improve cooking comfort, people have invented air-conditioning range hoods. The housing of air-conditioning range hoods includes air-conditioning components. In air-conditioning mode, the condenser of the air-conditioning component will generate heat. If the condenser is not effectively cooled, it will affect the heat exchange effect of the condenser, thereby reducing the energy efficiency of the air-conditioning. During the operation of the air conditioner, condensed water will condense on the surface of the evaporator. If the condensed water of the air conditioner is discharged, an external water pipe is required, which not only increases the installation cost, but also causes long-term erosion of the wall and dripping in the external environment. If the condensed water of the air conditioner accumulates in the body of the range hood, it is easy to cause local leakage and even affect the normal operation of the range hood.

[0005] The second technical problem to be solved by the present invention is to provide a condenser which can reduce the impact of water flow on the surface of the condenser and improve the capillary effect of the fins in view of the above-mentioned existing technical status.

[0007] As a preferred solution, the connector body is in a square box-shaped structure as a whole, the card interface is a card interface hole hollowed out in the middle of the connector body, and there are two water inlet interfaces which are respectively arranged on both sides of the connector body.

[0008] In order to ensure that the drainage and liquid distribution joint can discharge water smoothly after installation, the bottom of the water inlet interface is higher than the bottom of the joint body.

[0009] As another preferred solution, the water inlet interface is arranged in the middle of the connector body, and the card interface includes a first card interface and a second card interface, and the first card interface and the second card interface are respectively arranged on both sides of the water inlet interface.

[0010] In order to ensure that the drainage and liquid distribution joint can discharge water smoothly after installation, the bottom of the water inlet interface is higher than the bottom of the first card interface and the second card interface.

[0011] The technical solution adopted by the utility model to solve the above-mentioned second technical problem is: the condenser includes copper tubes distributed in a circuitous manner and fins arranged between the copper tubes, and is characterized in that: the drainage liquid distribution joint is installed on the bending section of the copper tube.

[0012] As an installation method, the card interface of the drainage and liquid distribution joint is a card connection hole, and the bent section is inserted into the card connection hole.

[0013] As another installation method, the card interface of the drainage and liquid distribution joint is a first card interface and a second card interface, and adjacent pipe sections of adjacent bending sections are respectively inserted into the first card interface and the second card interface.

[0014] In order to make the liquid distribution more uniform, there are at least two drainage and liquid distribution joints.

[0015] In order to allow the water flowing out of the drainage and liquid distribution joint to flow smoothly onto the fins, the condenser is arranged vertically, the bottom of the joint body of the drainage and liquid distribution joint is against the fins, and a water outlet gap is left between the water inlet interface of the joint body and the fins.

[0016] Compared with the prior art, the advantages of the utility model are: the drainage and liquid distribution joint is an integrally formed part, and a card interface and a water inlet interface are formed on the joint body. The structure is very simple and the cost is low. During installation, you only need to clamp the card interface on the copper tube of the condenser, and the installation is very convenient.

The copper fin tube has a very strong water storage capacity, which can make the condensed water fully contact with the condensing wind, fins and copper tubes, so as to achieve a very strong evaporation effect and evaporation capacity, and can effectively treat the condensed water generated by the operation of the air conditioner.

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] like Figures 1 to 3As shown, one of the drainage and liquid distribution joints of this embodiment is shown. The drainage and liquid distribution joint 1 includes a joint body 11, a card interface is formed on the joint body 11, and a water inlet interface 12 is also provided on the joint body 11. The joint body 11 and the water inlet interface 12 are integrally formed. Among them, the joint body 11 is a square box-shaped structure as a whole, the card interface is a card hole 13 hollowed out in the middle of the joint body 11, and there are two water inlet interfaces 12, which are respectively arranged on both sides of the joint body 11. In order to smoothly discharge water through the water inlet interface 12, the bottom of the water inlet interface 12 is higher than the bottom of the joint body 11.

[0027] like Figures 4 to 6 As shown, another drainage and liquid distribution joint of this embodiment also includes a joint body 11, a card interface is formed on the joint body 11, and a water inlet interface 12 is also provided on the joint body 11. The joint body 11 and the water inlet interface 12 are an integrally formed part. Among them, the water inlet interface 12 is arranged in the middle of the joint body 11. The card interface of this embodiment includes a first card interface 14 and a second card interface 15. The first card interface 14 and the second card interface 15 are respectively arranged on both sides of the water inlet interface 12. In order to smoothly discharge water through the water inlet interface 12, the bottom of the water inlet interface 12 is higher than the bottom of the first card interface 14 and the second card interface 15.

[0028] like Figure 7 and Figure 8 As shown, the condenser of this embodiment adopts a fin-type condenser, which includes a circuitously distributed copper tube 51 and fins (not shown in the figure) arranged between the copper tubes. The fins are arranged between the straight tube sections of the copper tubes. The copper fin tubes have a very strong water storage capacity. The fin-type condenser is an existing conventional structure. The specific structure can refer to the existing technology and will not be described in detail here.

[0029] In this embodiment, a drainage and liquid distribution joint 1 is installed on the bending section of the copper tube, and both of the above two drainage and liquid distribution joints with different structures can be installed. Figures 1 to 3 The drainage and liquid distribution joint shown in the figure has a bent section inserted into the inner interface of the clamping hole 13. Figures 4 to 6 The drainage and liquid distribution joint shown in the figure, the adjacent pipe sections of the adjacent bending sections can be respectively inserted into the first card interface 14 and the second card interface 15. After installation, when in use. The condenser is arranged vertically, the bottom of the joint body 11 of the drainage and liquid distribution joint 1 is against the fins, and a water outlet gap is left between the water inlet interface 12 of the joint body 11 and the fins, so that the water flowing in from the water inlet interface 12 can flow out smoothly from the bottom of the water inlet interface 12, thereby achieving pressure release and redistribution of the water flow, reducing the impact of the water flow on the surface of the condenser, and improving the capillary effect of the fins.

[0030] The condenser can be used in a refrigeration range hood, which includes air conditioning components such as a compressor, a condenser and an evaporator. The specific working principle can refer to the prior art. During the operation of the refrigeration system, the condensed water generated by the evaporator flows into the water box, and the water pump draws the accumulated condensed water to the drainage liquid distribution joint 1 above the condenser. The drainage liquid distribution joint 1 releases the water pressure generated by the water pump and enters the fins of the condenser in a free-flowing state until the entire condenser surface is filled. The liquid distribution structure is simple and efficient. Due to the high surface temperature of the condenser, part of the condensed water will evaporate and be discharged outdoors, and the unconsumed condensed water will flow back into the water box and continue to be extracted and circulated by the water pump. The condensed water is not directly discharged, avoiding many problems caused by direct discharge. In addition, the finned condenser has a strong water storage capacity, which can keep the condensed water on the surface for a long time, so that the condensed water can fully contact with the condensing wind, fins and copper tubes, and fully exchange heat with the surface of the condenser, achieving a strong evaporation effect and evaporation capacity, and can effectively deal with the condensed water generated by the operation of the air conditioner.
