Description

Technical Field

[0001] The utility model relates to a water-cooled condenser assembly for a kitchen and bathroom air conditioner, in particular to an efficient water-cooled condenser assembly for a kitchen and bathroom air conditioner, belonging to the technical field of condensers for integrated water-cooled air conditioners. Background Art

[0002] Generally, a compressor compresses low-temperature and low-pressure evaporator gas into high-temperature and high-pressure superheated steam, which is sent to a water-cooled condenser through the refrigerant copper tube inlet. After the superheated steam condenses and releases heat in the water-cooled condenser, it enters a subcooler through the refrigerant copper tube outlet and the connecting pipe, then enters a capillary tube from the subcooler for throttling and pressure reduction, and is sent to the evaporator through the connecting pipe. The heat after heat exchange is discharged through the water in the water-cooled condenser, thus carrying out a refrigeration cycle repeatedly.

[0003] During the above refrigeration process, the water-cooled condenser and the subcooler are connected by a connecting pipe to form a water-cooled air conditioner condenser assembly, which is used to increase the cooling effect, increase the subcooling degree of the refrigerant on the inlet side of the evaporator, reduce the enthalpy value, increase the enthalpy difference, and improve the system refrigeration capacity. However, due to the complex structure of the conventional water-cooled condenser and limited cooling effect, it cannot meet the needs of refrigeration air conditioners, especially small kitchen and bathroom air conditioners. For example:

[0004] The authorized announcement number is: CN201463309U, the application number is: CN2009201233268, and the utility model name is: Electrically-assisted super heat pipe heat transfer type solar heat pump water heater integrated machine. The heat exchange copper tube of the condenser is wound around and closely attached to the outer wall of the condenser inner tank. Tap water enters the inner cavity of the water tank through the inner tank of the condenser and the water supply pipe from the inlet and outlet pipe. Its structure requires the design of an inner tank, and the size and shape of the copper tube only match the inner tank, and the overall contact area with the cooling water is not large enough, so the cooling effect is limited.

[0005] The authorized announcement number is: CN213778169U, the application number is: 2020225491573, and the utility model name is: An air source heat pump water heating device. A spiral copper tube is fixedly arranged inside the condensation barrel. A rotating shaft is rotatably installed inside the condensation barrel. A plurality of stirring blades are respectively fixedly arranged on both sides of the rotating shaft, and all the plurality of stirring blades are arranged inside the copper tube. A motor is fixedly installed at the top of the condensation barrel, and the output shaft of the motor is fixedly connected to the top of the rotating shaft. Its structure requires the design of a rotating shaft, stirring blades and a motor, and the contact surface between the copper tube and the cooling water is very small, and the cooling effect is not ideal.

[0006] The above-mentioned prior art has a complex structure, unstable copper tube installation, inconvenient assembly, and poor cooling effect. In order to improve the cooling effect, it is necessary to increase the product volume and increase the production cost, which is completely unsuitable for the application and promotion of small kitchen and bathroom air conditioners. Content of the Utility Model

[0007] The object of the present utility model is to address the defects in the prior art of the water-cooled condenser assembly of kitchen and bathroom air conditioners, such as complex structure, unstable installation of copper pipes, inconvenient assembly, poor cooling effect, and inapplicability to the application and promotion of small kitchen and bathroom air conditioners. It provides an efficient water-cooled condenser assembly for kitchen and bathroom air conditioners, which can achieve the purposes of simplified structure, stable installation of copper pipes, convenient assembly, good cooling effect, reduced product volume, lower production cost, and full suitability for the application and promotion of small kitchen and bathroom air conditioners.

[0008] To achieve the above object, the technical solution adopted by the present utility model is: an efficient water-cooled condenser assembly for kitchen and bathroom air conditioners, including a water-cooled condenser, connecting pipes, a water inlet pipe, and a drain pipe. The water-cooled condenser includes a plastic upper cover, a plastic barrel body, a plastic bottom cover, and copper pipes. The plastic bottom cover is provided with a sealing edge, and the lower end of the plastic barrel body is fixedly sleeved and inserted into the sealing edge of the plastic bottom cover. A quick connector A is provided on the left side of the center of the plastic bottom cover, and a quick connector B is provided on the right side of the center of the plastic upper cover.

[0009] It also includes a sub-cooler, a water receiving tray, and a water pump.

[0010] The plastic barrel body is cylindrical, and more than 3 longitudinal grooves are evenly arranged on the inner wall of the plastic barrel body. The bottom of the longitudinal groove expands to both sides and forms convex heads on both sides.

[0011] The water-cooled condenser also includes more than 3 plastic strips. The shape and size of the outer side of the plastic strip match the shape and size of the longitudinal groove. More than 3 plastic strips are respectively clamped in more than 3 longitudinal grooves and are connected by insertion. The inner side of the plastic strip is arc-shaped, and the arc-shaped inner sides of more than 3 plastic strips are on the arc of the same circle.

[0012] The copper pipe is coiled into a cylindrical copper coil. The copper pipes of each layer of the cylindrical copper coil are in close contact with each other. The outer diameter of the cylindrical copper coil matches the size of the arc formed by the inner arc of the plastic strip. The cylindrical copper coil is arranged in the plastic strip and is in a tight fit with the inner arc of the plastic strip.

[0013] The upper end of the cylindrical copper coil extends upward from the center of the plastic upper cover to form a refrigerant copper pipe inlet, and the lower end of the cylindrical copper coil extends downward from the center of the plastic bottom cover to form a refrigerant copper pipe outlet.

[0014] Since the plastic strip is convenient to assemble and connect tightly with the plastic barrel body, the cylindrical copper coil is clamped in the plastic barrel body by the plastic strip, and its structure is very stable. Since the cylindrical copper coil is arranged closely against the inner side of the plastic strip and the upper and lower layers of copper pipes are in close contact with each other, the contact area between the copper pipe and the cooling water flowing in the water-cooled condenser is maximized, so that the cooling effect of the cooling water on the refrigerant in the copper pipe is optimized.

[0015] The water receiving tray is below the subcooler.

[0016] There are 3 longitudinal grooves evenly arranged on the inner wall of the plastic barrel body. The water-cooled condenser further includes 3 plastic clamping strips, and the 3 plastic clamping strips are respectively clamped in the 3 longitudinal grooves and are connected by plugging.

[0017] The diameter of the cylindrical copper coil pipe is 220 mm; the diameter of the plastic barrel body is 250 mm; the assembled height of the plastic upper cover, the plastic barrel body and the plastic bottom cover is 146 mm, and the overall height of the water-cooled condenser including the quick connector A and the quick connector B is 216.1 mm.

[0018] The subcooler is composed of a cylindrical cooling sleeve sleeved around the refrigerant pipe, and includes a subcooler refrigerant pipe inlet and a subcooler refrigerant pipe outlet. The refrigerant copper pipe outlet is connected to the subcooler refrigerant pipe inlet through a connecting pipe, and the subcooler refrigerant pipe outlet is connected to the capillary through a connecting pipe; in this way, during refrigeration, the refrigerant is first cooled by the water-cooled condenser and then enters the subcooler for secondary cooling, thereby increasing the supercooling degree of the refrigerant in the refrigerant outlet pipe and improving the refrigeration effect; due to the increased volume of the cylindrical water pipe, more water can be filled, and the cooling effect is more significantly increased.

[0019] The compressor compresses the low-temperature and low-pressure evaporator gas into high-temperature and high-pressure superheated steam and sends it to the condenser through the refrigerant copper pipe inlet. After the superheated steam condenses and releases heat in the condenser, it enters the subcooler through the connecting pipe from the refrigerant copper pipe outlet, and then enters the capillary for throttling and pressure reduction, and is sent to the indoor unit evaporator for refrigeration through the connecting pipe. The heat after heat exchange is discharged through the water in the water-cooled condenser, so as to carry out the refrigeration cycle repeatedly.

[0020] A quick connector C is arranged below the left end of the subcooler, and a quick connector D is arranged above the right end of the subcooler. A three-way quick connector is also arranged between the water-cooled condenser and the subcooler; low-temperature tap water flows through the quick connector from the water inlet pipe and enters the water-cooled condenser to cool the high-temperature and high-pressure refrigerant in the cylindrical copper coil pipe for the first time; then it flows out from the quick connector B to the three-way quick connector; the drain pipe is arranged behind the three-way quick connector, and the waste water from the air conditioner water receiving tray is pumped into the cylindrical cooling sleeve of the subcooler through the water pump and the quick connector C. After the refrigerant in the water-cooled condenser is first cooled, it flows into the refrigerant pipe in the subcooler in the opposite direction of the condensate flow to cool the refrigerant in the refrigerant pipe for the second time; then, it flows out from the quick connector D to the three-way quick connector to meet the cooling water flowing out of the water-cooled condenser, and then is discharged outdoors together with the kitchen water through the drain pipe at the kitchen sink drain outlet;

[0021] The quick connector A, the quick connector B, the quick connector C and the quick connector D are 2-minute right-angle quick connectors.

[0022] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0023] (1) A structure is designed in which the shape and size of the plastic strip are matched with and inserted into the shape and size of the longitudinal groove, simplifying the structure of the water-cooled condenser, facilitating assembly, and ensuring stable installation of the copper tube.

[0024] (2) The copper tube is coiled into a cylindrical copper coil, which is convenient for assembly, has good cooling effect, reduces the product volume, lowers the production cost, and is completely suitable for the application and popularization of small kitchen and bathroom air conditioners.

Detailed Implementation Manner

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model. The "left, right, front, and back" described in this embodiment are for convenience of description, and technical solutions with opposite directions and the same structures are within the scope of protection of this application.

[0035] As Figures 1 to 8 shown, a component of an efficient kitchen and bathroom air conditioner water-cooled condenser 1, as Figure 1 and Figure 2 shown, includes a water-cooled condenser 1, a connecting pipe 3, a water inlet pipe 4, and a drain pipe 5. The water-cooled condenser 1 includes a plastic upper cover 101, a plastic barrel body 102, a plastic bottom cover 103, and a copper pipe 104. The plastic bottom cover 103 is provided with a sealing edge 105, and the lower end of the plastic barrel body 102 is fixedly sleeved and inserted into the sealing edge 105 of the plastic bottom cover 103. A quick connector A 6 is provided on the left side of the center of the plastic bottom cover 103, and a quick connector B 7 is provided on the right side of the center of the plastic upper cover 101. It also includes a sub-cooler 2, a water receiving tray 11, and a water pump 12.

[0036] As Figure 2 、 Figure 3 and Figure 4 shown, the plastic barrel body 102 is cylindrical, and more than 3 longitudinal grooves 106 are uniformly arranged on the inner wall of the plastic barrel body 102. The bottom of the longitudinal groove 106 expands towards both sides and forms convex heads 108 on both sides.

[0037] As Figure 2 、 Figure 5 and Figure 6 shown, the water-cooled condenser 1 further includes more than 3 plastic strips 107. The shape and size of the outer side of the plastic strip 107 match the shape and size of the longitudinal groove 106. More than 3 plastic strips 107 are respectively clamped in more than 3 longitudinal grooves 106 and are connected by insertion. The inner side of the plastic strip 107 is arc-shaped, and the arc-shaped inner sides of more than 3 plastic strips 107 are on the arc of the same circle.

[0038] The copper pipe 104 is coiled into a cylindrical copper coil, and each layer of the copper pipe 104 in the cylindrical copper coil is in close contact. The outer diameter of the cylindrical copper coil matches the size of the arc formed by the inner arc of the plastic strip 107, and the cylindrical copper coil is arranged in the plastic strip 107 and is in a tight fit with the inner arc of the plastic strip 107.

[0039] As Figure 1As shown, the upper end of the cylindrical copper coil tube extends upward at the center of the plastic upper cover 101 to form a refrigerant copper tube inlet 109, and the lower end of the cylindrical copper coil tube extends downward at the center of the plastic bottom cover 103 to form a refrigerant copper tube outlet 1010;

[0040] Since the plastic strip 107 is convenient to assemble with the plastic barrel body 102 and the connection is firm, the cylindrical copper coil tube is clamped in the plastic barrel body 102 by the plastic strip 107, and its structure is very stable; since the cylindrical copper coil tube is arranged close to the inner side of the plastic strip 107, and the upper and lower layer copper tubes 104 are in close contact with each other, the contact area between the copper tube 104 and the cooling water flowing in the water-cooled condenser 1 is maximized, so that the cooling effect of the cooling water on the refrigerant in the copper tube 104 is optimized.

[0041] As Figure 5 and Figure 6 shown, three longitudinal grooves 106 are uniformly arranged on the inner wall of the plastic barrel body 102, and the water-cooled condenser 1 further includes three plastic strips 107, and the three plastic strips 107 are respectively clamped in the three longitudinal grooves 106 and are connected by plugging.

[0042] As Figure 5 shown, the diameter φ1 of the cylindrical copper coil tube is 220 mm; the diameter φ2 of the plastic barrel body 102 is 250 mm; as Figure 7 shown, the height h after the plastic upper cover 101, the plastic barrel body 102 and the plastic bottom cover 103 are assembled is 146 mm, and the overall height H of the water-cooled condenser 1 including the quick connector A 6 and the quick connector B 7 is 216.1 mm.

[0043] As Figure 8 shown, the sub-cooler 2 is composed of a cylindrical cooling sleeve sleeved around the refrigerant pipe, and includes a sub-cooler refrigerant pipe inlet 201 and a sub-cooler refrigerant pipe outlet 202. The refrigerant copper tube outlet 1010 is connected to the sub-cooler refrigerant pipe inlet 201 through the connecting pipe 3, and the sub-cooler refrigerant pipe outlet 202 is connected to a capillary tube (not shown in the figure) through the connecting pipe 3; in this way, during refrigeration, the refrigerant is first cooled by the water-cooled condenser 1 and then enters the sub-cooler 2 for secondary cooling, thereby increasing the sub-cooling degree of the refrigerant in the refrigerant outlet pipe and improving the refrigeration effect; since the volume of the cylindrical water pipe increases, more water can be filled, and the cooling effect is increased more significantly.

[0044] A compressor (not shown in the figure) compresses the low-temperature and low-pressure evaporator gas into high-temperature and high-pressure superheated steam, which is sent to the condenser through the refrigerant copper tube inlet 109. After the superheated steam condenses and releases heat in the condenser, it enters the subcooler 2 through the refrigerant copper tube outlet 1010 and the connecting pipe 3, then enters the capillary tube for throttling and pressure reduction, and is sent to the indoor evaporator (not shown in the figure) through the connecting pipe 3 for refrigeration. The heat after heat exchange is discharged through the water in the water-cooled condenser 1, thus repeating the refrigeration cycle.

[0045] As Figure 1 and Figure 8 shown, a quick connector C 8 is provided below the left end of the subcooler 2, and a quick connector D 9 is provided above the right end of the subcooler 2. A three-way quick connector 10 is also provided between the water-cooled condenser 1 and the subcooler 2; low-temperature tap water flows through the quick connector from the water inlet pipe 4 into the water-cooled condenser 1 to first cool the high-temperature and high-pressure refrigerant in the cylindrical copper coil; then it flows out from the quick connector B 7 to the three-way quick connector 10; the drain pipe 5 is arranged at the rear side of the three-way quick connector 10, and the waste water in the water receiving tray 11 is pumped into the cylindrical cooling sleeve of the subcooler 2 through the water pump 12 and the quick connector C 8. After the refrigerant in the water-cooled condenser 1 is first cooled, it flows into the refrigerant pipe in the subcooler 2 in the opposite direction to the flow of the condensed water to second-cool the refrigerant in the refrigerant pipe; then, it flows out from the quick connector D 9 to the three-way quick connector 10 to meet the cooling water flowing out from the water-cooled condenser 1, and then is discharged to the outside through the drain pipe 5 at the kitchen sink drain outlet (not shown in the figure) together with the kitchen water;

[0046] The quick connector A 6, the quick connector B 7, the quick connector C 8 and the quick connector D 9 are 1 / 4-inch right-angle quick connectors.

[0047] The above-described embodiments are only relatively preferred embodiments of the present invention.
