Description

Technical Field

[0001] This utility model relates to the field of air source heat pump technology, and in particular to a water collection tray device for defrosting the outdoor unit of an air source heat pump unit. Background Technology

[0002] The defrosting tray for the outdoor unit of an air source heat pump is a common auxiliary cooling and defrosting device. Its main function is to collect and drain the moisture and snow melt generated during the defrosting process, ensuring the normal operation of the equipment and preventing damage caused by water accumulation. An air source heat pump unit is a device that utilizes the heat energy in the air, converting it through a compressor and heat exchanger for heating, cooling, and hot water supply.

[0003] However, most traditional defrosting water trays can only perform defrosting and cannot reuse the cryogenic liquid after defrosting, thus reducing the efficiency of the device. In addition, they usually rely on water flow for heat dissipation and defrosting. In cold environments, the water flow is not smooth or it freezes, which affects the normal operation of the device and also affects its performance in low-temperature conditions.

[0004] Therefore, those skilled in the art have provided a defrosting drip tray device for outdoor units of air source heat pump units to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a defrosting water tray device for outdoor units of air source heat pump units. This defrosting mechanism is equipped with multiple conveying channels, which are folded and arranged inside the outer casing. This allows the defrosting liquid to flow inside the casing, guiding the heat generated by the unit equipment inside the casing, thereby improving heat guidance and heat dissipation, reducing the workload of the compressor and other core equipment. Furthermore, driven by a first fan, airflow can be transmitted to the conveying channels through the air duct. This not only cools the unit in the absence of water but also guides the heat generated by the unit to the water tray and the bottom of the casing, thereby improving the heat dissipation effect and reducing heat loss.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A defrosting water tray device for an outdoor unit of an air source heat pump unit includes a housing. A defrosting mechanism is provided on the upper surface of the housing. The defrosting mechanism includes a mounting slot and an air supply channel. A water tray is fitted into the inner wall of the mounting slot. Iron filter screens are fixedly connected to the inner walls on both sides of the water tray. Multiple collection slots are provided on the inner walls on both sides of the mounting slot. A conveying channel is provided on the inner bottom surface of the collection slot. An exhaust inclined channel is provided in the middle of the inner wall on one side of the conveying channel. A first air inlet shell is fixedly connected to the outer wall at the rear end of the air supply channel. A first fan is fixedly connected to the front end of the inner wall of the first air inlet shell. A first mounting frame is fitted into the rear end of the lower surface of the first air inlet shell. A first fiber filter screen is fixedly connected to the inner wall of the first mounting frame.

[0008] A door panel is hinged to the front end of the inner wall of the outer shell, and a heat dissipation mechanism is provided at the rear end of the outer shell. The heat dissipation mechanism includes a heat dissipation groove and a second air intake shell. A second fan is fixedly connected to the front end of the inner wall of the second air intake shell. A limit slot is opened at the rear end of the middle part of the inner wall of the second air intake shell. A second mounting frame is engaged with the rear end of the lower part of the second air intake shell. A second fiber filter is fixedly connected to the inner wall of the second mounting frame.

[0009] Through the above technical solution, the device is equipped with a heat dissipation mechanism. Combined with a glass fiber filter, the second fan can not only dissipate heat and cool the unit equipment installed inside the casing, but also reduce the possibility of dust entering the interior, thereby reducing the entry of pollutants into the internal components, and thus reducing the equipment failure rate and maintenance costs.

[0010] Furthermore, the mounting slot is located at the center of the upper surface of the housing;

[0011] The above technical solution enables the water receiving tray to be bolted onto the outer casing.

[0012] Furthermore, the air supply duct is fixedly connected to the center of the outer wall at the rear end of the housing, and exhaust ports are provided at the upper ends of the outer walls on both sides of the air supply duct.

[0013] The above technical solution enables the gas delivery duct to deliver airflow into the gas delivery duct through the exhaust port.

[0014] Furthermore, multiple first guide plates are fixedly connected to the rear ends of the inner walls on both sides of the first air intake shell;

[0015] The above technical solution reduces the possibility of rainwater entering the first air intake shell by setting a first guide ramp.

[0016] Furthermore, the heat dissipation grooves are respectively opened on the outer wall of the front end of the door panel, and multiple second guide plates are fixedly connected to the rear ends of the inner walls on both sides of the second air intake shell.

[0017] The above technical solution enables the heat dissipation groove and the second guide plate to reduce the possibility of rainwater entering the casing.

[0018] Furthermore, the second air intake shell is fixedly connected to the upper and lower parts of the rear end outer wall of the outer shell, respectively;

[0019] The above technical solution enables the second air intake shell to generate airflow into the outer shell for heat dissipation and cooling.

[0020] Furthermore, a support frame is fixedly connected to the lower surface of the outer shell, and a partition plate is fixedly connected to the center of the inner wall of the outer shell;

[0021] The above technical solution allows for the installation of various unit components within the casing by setting up partition plates.

[0022] Furthermore, a lock is provided at the center of one side of the front outer wall of the door panel;

[0023] The above technical solution allows the door panel to be locked to the outer shell by setting a lock.

[0024] This utility model has the following beneficial effects:

Compared with most traditional defrosting water tray devices for outdoor units of air source heat pump units, this defrosting mechanism is equipped with multiple conveying channels, which are folded and arranged inside the outer shell. This allows the defrosting liquid to flow inside the outer shell, so as to guide the heat generated by the unit equipment inside the shell, thereby improving the heat guiding and heat dissipation effect, reducing the workload of the compressor and other core equipment. Furthermore, driven by the first fan, airflow can be transmitted to the conveying channels through the air duct. This not only cools the unit in the absence of water, but also guides the heat generated by the unit to the water tray and the bottom of the outer shell, thereby improving the heat dissipation effect and reducing heat loss.

[0026] 2. The present invention proposes a defrosting drip tray device for outdoor units of air source heat pump units. Compared with most traditional defrosting drip tray devices for outdoor units of air source heat pump units, this device is equipped with a heat dissipation mechanism. Combined with a glass fiber filter, the second fan can not only dissipate heat and cool the unit equipment installed inside the casing, but also reduce the possibility of dust entering the interior, thereby reducing the entry of pollutants into the internal components, and thus reducing the equipment failure rate and maintenance costs.

[0045] Working principle: First, the air source heat pump unit is installed inside the outer casing 1. When the equipment is started, the first fan 2010 and the second fan 303 (EcoFan, MP series) start. The first fan 2010 delivers airflow through the air duct 206 (exhaust chute 208 reduces the possibility of water flowing into the air duct 206) to the middle of the conveying trough 205 (multiple conveying troughs 205 can guide the hot air generated by the unit inside the outer casing 1). The airflow is discharged from both ends of the conveying trough 205 (when flowing, it adsorbs and guides the hot air in the conveying trough 205). When discharged from the top, it blows towards the frost in the water receiving tray 202. The airflow discharged from the bottom is easily dispersed around the perimeter of the outer casing 1, thus assisting in defrosting. The liquid defrosted from the water receiving tray 202 is injected into the conveying trough 205 for flow, thereby cooling the equipment. The second fan 303 normally cools the equipment inside the outer casing 1, and works with the fiber filter to reduce the possibility of dust.
