Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning type range hoods, in particular to a liquid distributor for a condenser, a condenser and an air-conditioning type range hood. Background Art

[0002] The air-conditioning 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 cook's cooking experience. 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 conditioner. 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 (condenser) of the air-conditioning type range hood in the above patent application still has certain shortcomings. The existing conventional liquid distributor only sprinkles water on the top of the condenser through multiple liquid outlets arranged at intervals. The water flows naturally under the action of gravity and flows down along the surface of the condenser. This method cannot make the water flow evenly cover the surface of the condenser. That is, the surface of the condenser is only partially covered by the water flow, and most areas are not covered by the water flow, resulting in limited heat dissipation effect of the condenser.

[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0028] In the specification and claims of the present invention, terms indicating directions, such as "front", "rear", "up", "down", "left", "right", "side", "top", "bottom", etc., are used to describe various exemplary structural parts and elements of the present invention, but these terms are used here only for the purpose of convenience of description and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in the present invention can be arranged in different directions, these terms indicating directions are only used as explanations and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0029] Figure 1-Figure 7 The preferred embodiments of the liquid distributor for condenser, condenser and air-conditioning type range hood of the utility model are shown. The liquid distributor includes a liquid distributor body 10, and the liquid distributor body 10 is installed on the top of the condenser. The liquid distributor includes a liquid distributor body 10 on which a water inlet 121 is provided. The liquid distributor body 10 is hollow inside to form a water storage chamber. Specifically, the water storage chamber includes a water inlet chamber 12 extending in the horizontal direction and a water outlet chamber 13 connected to the side of the water inlet chamber 12 and extending downward as a whole. Figure 4 As shown, the upper and lower dimensions of the water outlet chamber 13 are larger than the upper and lower dimensions of the water inlet chamber 12. Therefore, when viewed from the side, the water storage chamber (water inlet chamber 12 and water outlet chamber 13) of the liquid distributor body 10 is an inverted L-shaped structure. A water inlet 121 is formed at one end of the water inlet chamber 12, and the other end away from the water inlet 121 is a closed structure. The water inlet 121 at the end of the water inlet chamber 12 can be connected to an external water supply pipeline. The bottom wall of the water outlet chamber 13 is provided with water outlets 132 arranged in sequence along its extension direction.

[0030] In this embodiment, the side wall of the water outlet chamber 13 away from the water inlet chamber 12 is recorded as the first side wall 131, and the side wall of the water inlet chamber 12 opposite to the first side wall 131 in the horizontal direction is recorded as the second side wall 122. A plurality of water blocking bars 14 are sequentially arranged on the first side wall 131 of the water outlet chamber 13 along the extension direction of the water outlet chamber 13 (i.e., along the left-right direction), and a water outlet 132 is opened on the bottom wall of the water outlet chamber 13 at a position corresponding to the area between two adjacent water blocking bars 14 (vertical projection). Figure 5As shown, each water retaining bar 14 extends from the first side wall 131 of the water outlet chamber 13 toward the second side wall 122 of the water inlet chamber 12 and bends toward the water inlet 121 , wherein the length of each water retaining bar 14 increases sequentially along the water flow direction in the water inlet chamber 12 . More specifically, each water retaining bar 14 includes a water retaining section 141 connected to the first side wall 131 of the water outlet chamber 13, and a water diversion section 142 connected to the side of the water retaining section 141 away from the first side wall 131, wherein the water retaining section 141 is substantially perpendicular to the first side wall 131, and the water diversion section 142 is inclined toward the location of the water inlet 121 along the direction from the first side wall 131 to the second side wall 122, wherein the length of the water retaining section 141 of each water retaining bar 14 is consistent, and the length of the water diversion section 142 increases sequentially along the direction of water flow in the water inlet chamber 12, which can also be understood as the spacing between each water retaining bar 14 and the second side wall 122 of the water inlet chamber 12 decreases sequentially along the direction of water flow in the water inlet chamber 12. Figure 5 As shown, in order to better guide the water flow from the water inlet chamber 12 into the water outlet chamber, the angle formed between the water retaining section 141 and the water diversion section 142 of each water retaining bar 14 is recorded as A, wherein the value range of A is: 120°≤A≤150°.

[0031] The water flow entering the water inlet chamber 12 from the water inlet 121 can enter the water outlet chamber 13 under the guidance of each water guide bar. Since the length of each water blocking bar 14 increases successively along the water flow direction in the water inlet chamber 12, it can be ensured that the amount of water flowing out of each water outlet 132 at the bottom of the water outlet chamber 13 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.

[0032] The opening direction of the water inlet 121 at the end of the water inlet chamber 12 of the liquid distributor of this embodiment is consistent with the extension direction of the water inlet chamber 12. In this way, it can be ensured that the water flow entering the water inlet chamber 12 from the water inlet 121 has a sufficient flow rate and can flow smoothly to the end position of the water inlet chamber 12 away from the water inlet 121, thereby further ensuring the uniformity of the amount of water flowing out of each water outlet 132 at the bottom of the water outlet chamber 13.

[0033] The bottom of the liquid distributor body 10 (specifically the water outlet chamber 13) is also provided with a connecting plate 11 for connecting with the top of the condenser.

[0034] The present embodiment also relates to a condenser, including a condenser body and a liquid distributor arranged on the top of the condenser body, and the liquid distributor adopts the above-mentioned liquid distributor structure. Specifically, the condenser of the present embodiment is a fin-type condenser. The fin-type condenser includes heat exchange fins 22 arranged in sequence and heat exchange tubes 21 passing through each heat exchange fin 22. The above-mentioned liquid distributor is installed on the top of the heat exchange fins 22 of the condenser through a connecting plate 11, and each water outlet 132 of the water outlet chamber 13 faces downward, that is, toward the heat exchange fins 22. Since the fin-type condenser has a very strong water storage capacity, the condensed water can be fully contacted with the condensing wind, fins and copper tubes, achieving a very strong evaporation effect and evaporation capacity, and can effectively treat the condensed water generated by the operation of the air conditioner.

[0035] The present embodiment also relates to an air-conditioning type range hood, which comprises a casing, a compressor and a range hood fan are arranged in the casing, a smoke exhaust passage is formed downstream of the range hood fan, an air-conditioning indoor unit is mounted on the casing, the air-conditioning indoor unit comprises an evaporator, a condenser is mounted in the smoke exhaust passage, the condenser is the above-mentioned condenser, the compressor, the condenser and the 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.
