Description

Technical Field

[0001] The utility model relates to the technical field of range hoods, in particular to a condenser device for a refrigeration range hood and a refrigeration range hood. Background Art

[0002] The refrigeration range hood integrates the air conditioning component with the range hood, and an air conditioning outlet is opened on the shell of the range hood. The air conditioning range hood can work in multiple different modes. As long as the air conditioning mode is turned on, the air conditioning outlet will blow out cold air or hot air, which can be blown directly to the cook or to the kitchen, thereby effectively improving the cooking experience of the cook. After the air conditioning mode is turned on, the condenser of the air conditioning component will generate heat. If the condenser is not effectively dissipated, the heat exchange effect of the condenser will be affected, thereby reducing the energy efficiency of the air conditioning. At the same time, condensed water will condense on the surface of the evaporator. If the air conditioning condensed water 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 air conditioning condensed water 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.

[0003] In order to solve the above technical problems, the Chinese invention patent application with application number CN202210024219.X (application publication number: CN115342403A) discloses an air-conditioning type range hood and its refrigeration and dehumidification dual-mode combined control method. A compressor and a range hood fan are provided in the casing of the range hood, and a condenser is installed in the smoke exhaust channel. The condensed water condensed on the surface of the evaporator of the air conditioner can flow into the water box. The water in the water box is transported to the liquid distributor of the condenser through a water pump. The condensed water flowing down the surface of the condenser flows back into the water box. A liquid level sensor is installed in the water box. The controller reads the ambient temperature data monitored by the temperature sensor and the liquid level data monitored by the liquid level sensor. When the ambient temperature is greater than the set minimum startup temperature, it chooses to enter the cooling mode, and when the liquid level data reaches the set warning value, it enters the dehumidification mode.

[0004] However, the condenser of the air-conditioning range hood in the above patent application still has certain shortcomings. After the water in the water box is sent to the top of the condenser, the water flows naturally under the action of gravity, but when passing through the U-hole of the condenser, it will reach the bottom without any hindrance and cannot fully exchange heat with the heat exchange fins of the condenser, resulting in relatively low evaporation efficiency. Utility Model Content

[0005] The first technical problem to be solved by the utility model is to provide a condenser device for a refrigeration range hood that can effectively slow down the outflow speed of condensed water, prolong the heat exchange time with the fins, and improve the heat exchange evaporation efficiency in response to the current status of the existing technology.

[0006] The second technical problem to be solved by the utility model is to provide a range hood using the condenser device for the refrigeration range hood according to the current status of the prior art.

[0007] The technical solution adopted by the utility model to solve the above-mentioned first technical problem is: a condenser device for a refrigeration range hood, comprising a condenser body, the condenser body comprising:

[0008] Heat exchange fins arranged sequentially from top to bottom;

[0009] The condenser tube is arranged on each of the above-mentioned heat exchange fins from top to bottom;

[0010] It also includes water absorbing strips which are passed through each of the heat exchange fins from top to bottom.

[0011] In order to facilitate the installation of the water absorption strip, each of the heat exchange fins is further provided with mounting holes which are opposite to each other in the up and down directions, and the water absorption strip is arranged in the mounting holes of each of the heat exchange fins.

[0012] In order to make the condensed water more evenly and fully arranged on each heat exchange fin, the water absorption strips are arranged in sequence along the lateral direction of the condenser body.

[0013] As an improvement, the condenser is a U-shaped tube.

[0014] In order to ensure that the condensed water delivered to the top of the condenser is in uniform contact with each water absorption strip, a liquid distributor is provided on the top of the main body of the condenser. The liquid distributor has a water inlet and a water outlet. The top of the water absorption strip is opposite to the water outlet.

[0015] As an improvement, the liquid distributor is open at the bottom and defines a water storage chamber together with the top of the condenser body, and the top end of the water absorption strip extends into the water storage chamber.

[0016] In order to match with a plurality of water absorption strips sequentially arranged along the lateral direction of the condenser body, the condenser body as a whole is in a flat shape extending laterally, and the liquid distributor is in a long strip shape and is arranged along the lateral extension of the condenser body.

[0017] As an improvement, the water storage chamber includes a water inlet chamber extending in the horizontal direction and a water outlet chamber connected to the side of the water inlet chamber and extending downward as a whole. A water inlet is formed at one end of the water inlet chamber, and water outlets are arranged in sequence along its extension direction on the bottom wall of the water outlet chamber. The side wall of the water outlet chamber away from the water inlet chamber is recorded as the first side wall, and the side wall of the water inlet chamber opposite to the first side wall in the horizontal direction is recorded as the second side wall. A plurality of water blocking bars are arranged in sequence on the first side wall of the water outlet chamber along the extension direction of the water outlet chamber, and each water blocking bar extends from the first side wall of the water outlet chamber toward the second side wall of the water inlet chamber and bends toward the position of the water inlet, and the length of each water blocking bar increases in sequence along the water flow direction in the water inlet chamber.

[0018] Since a plurality of water-blocking bars are sequentially arranged on the first side wall of the water outlet chamber along the extension direction of the water outlet chamber, each water-blocking bar extends from the first side wall of the water outlet chamber toward the second side wall of the water inlet chamber and bends toward the location of the water inlet, and the length of each water-blocking bar increases sequentially along the water flow direction in the water inlet chamber, thereby, the water flow entering the water inlet chamber from the water inlet can enter the water outlet chamber under the guidance of each water guide bar, and ensure that the amount of water flowing out of each water outlet at the bottom of the water outlet chamber tends to be consistent, so that the water flow flowing out of the liquid distributor can be more evenly distributed on the side wall of the condenser, thereby realizing the pressure release and redistribution of the water flow, reducing the impact of the water flow on the surface of the condenser, and improving the heat dissipation effect of the condenser.

[0019] The technical solution adopted by the utility model to solve the second technical problem is: a refrigeration range hood, including a condenser, and the condenser adopts the above-mentioned condenser device.

[0020] As an improvement, it includes a casing, a compressor and a fume extractor fan are arranged in the casing, a smoke exhaust channel is formed downstream of the fume extractor fan, an air-conditioning indoor unit is installed on the casing, the air-conditioning indoor unit includes an evaporator, the condenser is installed in the smoke exhaust channel, the compressor, condenser and evaporator are connected by a refrigerant pipeline, a water box is provided in the casing, condensed water condensed on the surface of the evaporator can flow into the water box, the water in the water box is transported to the liquid distributor of the condenser by a water pump, and the condensed water flowing down from the surface of the condenser flows back into the water box.

[0021] Compared with the prior art, the utility model has the following advantages: after adding water absorption strips to each heat exchange fin of the condenser body, the outflow speed of condensed water can be effectively slowed down, the heat exchange time between condensed water and heat exchange fins can be prolonged, and the heat exchange evaporation efficiency of the condenser can be improved. The refrigeration range hood of the utility model can effectively handle the condensed water generated by the operation of the air conditioner, avoid many problems caused by the direct discharge of condensed water, and improve the user experience.

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings.

For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0031] Figure 1-Figure 7 The condenser device for a refrigerating range hood and a preferred embodiment of the refrigerating range hood of the utility model are shown. The condenser device includes a condenser body 10 and a liquid distributor 30 arranged on the top of the condenser body 10. The condenser is a finned condenser. The condenser body 10 includes heat exchange fins 12 arranged in sequence from top to bottom and a plurality of condensing tubes 11 passing through each heat exchange fin 12. Each condensing tube 11 is a U-shaped tube connected by bending at the end.

[0032] See also Figure 5, the lateral dimension of the condenser body 10 is larger than the longitudinal dimension, so that the whole structure is flat. The condenser tubes 11 have two groups arranged in sequence in the lateral direction of the condenser body 10. In order to reasonably carry out the spatial layout and make the condenser body more compact, the arrangement postures of the condenser tubes 11 in the two groups of condenser tubes 11 can be different. The heat exchange fins 12 are also provided with water absorption strips 20 extending up and down in the area corresponding to the area between the two groups of condenser tubes 11. Specifically, each heat exchange fin 12 is also provided with mounting holes 120 opposite to each other in the up and down direction, wherein a row of mounting holes 120 opposite to each other in the up and down direction on each heat exchange fin 12 is recorded as a mounting hole 120 group, and a water absorption strip 20 can be installed. In order to enable the condensed water to be more evenly and fully arranged on each heat exchange fin 12, the water absorption strip 20 has a plurality of mounting holes 120 arranged in sequence along the transverse direction of the condenser body. That is, each heat exchange fin 12 of the condenser body can be provided with a plurality of mounting holes 120 arranged in sequence along the transverse direction. Thus, each heat exchange fin 12 of the condenser body forms a plurality of mounting hole 120 groups arranged in sequence in the transverse direction of the condenser body. Figure 4 A schematic diagram showing the process of condensed water passing through the water absorption strip of the condenser device of this embodiment is shown, and the flow direction of the condensed water is indicated by the arrow.

[0033] See also Figure 7 , the liquid distributor 30 is installed on the top of the condenser body 10 through the connecting plate 31. The liquid distributor 30 includes a liquid distributor body on which a water inlet 321 is provided. The interior of the liquid distributor body is hollow to form a water storage chamber 300. Specifically, the water storage chamber 300 includes a water inlet chamber 32 extending in the horizontal direction and a water outlet chamber 33 connected to the side of the water inlet chamber 32 and extending downward as a whole. The upper and lower dimensions of the water outlet chamber 33 are larger than the upper and lower dimensions of the water inlet chamber 32. Therefore, from the side, the water storage chamber 300 (water inlet chamber 32 and water outlet chamber 33) of the liquid distributor body is an inverted L-shaped structure. A water inlet 321 is formed at one end of the water inlet chamber 32, and the other end away from the water inlet 321 is a closed structure. The water inlet 321 at the end of the water inlet chamber 32 can be connected to an external water supply pipeline. The bottom wall of the water outlet chamber 33 is provided with water outlets 332 arranged in sequence and at intervals along the extending direction thereof. The top end of the water absorbing strip 20 extends into the water outlet chamber 33 of the liquid distributor.

[0034] In this embodiment, the side wall of the water outlet chamber 33 away from the water inlet chamber 32 is recorded as the first side wall 331, and the side wall of the water inlet chamber 32 opposite to the first side wall 331 in the horizontal direction is recorded as the second side wall 322. A plurality of water blocking bars 34 are sequentially arranged on the first side wall 331 of the water outlet chamber 33 along the extension direction of the water outlet chamber 33 (i.e., along the left-right direction), and a water outlet 332 is opened on the bottom wall of the water outlet chamber 33 corresponding to the area between two adjacent water blocking bars 34 (vertical projection). Each water blocking bar 34 extends from the first side wall 331 of the water outlet chamber 33 toward the second side wall 322 of the water inlet chamber 32, and bends toward the location of the water inlet 321, wherein the length of each water blocking bar 34 increases sequentially along the water flow direction in the water inlet chamber 32. More specifically, each water retaining bar 34 includes a water retaining section 341 connected to the first side wall 331 of the water outlet chamber 33, and a water diversion section 342 connected to the side of the water retaining section 341 away from the first side wall 331, wherein the water retaining section 341 is basically perpendicular to the first side wall 331, and the water diversion section 342 is inclined toward the position of the water inlet 321 along the direction from the first side wall 331 to the second side wall 322, wherein the length of the water retaining section 341 of each water retaining bar 34 is consistent, and the length of the water diversion section 342 increases successively along the direction of water flow in the water inlet chamber 32. It can also be understood that the distance between each water retaining bar 34 and the second side wall 322 of the water inlet chamber 32 decreases successively along the direction of water flow in the water inlet chamber 32.

[0035] The water flow entering the water inlet chamber 32 from the water inlet 321 can enter the water outlet chamber 33 under the guidance of each water guide bar. Since the length of each water blocking bar 34 increases successively along the water flow direction in the water inlet chamber 32, it can be ensured that the amount of water flowing out of each water outlet 332 at the bottom of the water outlet chamber 33 tends to be consistent. In this way, the water flow flowing out of the liquid distributor can be more evenly distributed on the side wall of the condenser, realizing the pressure release and redistribution of the water flow, reducing the impact of the water flow on the surface of the condenser, and improving the heat dissipation effect of the condenser.

[0036] Each water outlet 332 of the water outlet chamber 33 faces downward, that is, toward the heat exchange fin 12, and is opposite to the mounting hole 120 on the heat exchange fin 12 for mounting the water absorption strip 20. Since the fin-type condenser has a very strong water storage capacity, the condensed water can be fully contacted with the condensing wind, the fins and the copper tube, achieving a very strong evaporation effect and evaporation capacity, and can effectively handle the condensed water generated by the operation of the air conditioner. In particular, after the water absorption strip 20 is added to each heat exchange fin 12 of the condenser body, the outflow speed of the condensed water can be effectively slowed down, the heat exchange time between the condensed water and the heat exchange fin 12 is extended, and the heat exchange evaporation efficiency of the condenser is improved.

[0037] The present embodiment also relates to a refrigeration range hood, which includes a casing, a compressor and a range hood fan are arranged in the casing, a smoke exhaust channel is formed downstream of the range hood fan, an air-conditioning indoor unit is installed on the casing, the air-conditioning indoor unit includes an evaporator, a condenser is installed in the smoke exhaust channel, the condenser adopts the above-mentioned condenser, the compressor, condenser and evaporator are connected by a refrigerant pipeline, a water box is arranged in the casing, condensed water condensed on the surface of the evaporator can flow into the water box, the water in the water box is transported to the liquid distributor of the condenser by a water pump, and the condensed water flowing down from the surface of the condenser flows back into the water box.
