Description

Technical Field

[0001] The utility model relates to the technical field of air - source heat pump units, in particular to an evaporator base and a heat pump. Background Art

[0002] An air - source heat pump utilizes the heat in the air to generate heat energy. The internal condenser and evaporator main body work continuously in a cycle to transfer the heat. Since the heat pump cools the air while providing heat, the moisture in the air condenses into liquid water. In an environment with a relatively high humidity, more condensate is generated, and the condensate flows out from below the evaporator main body. If the condensate cannot be discharged in time, it will cause an increase in the humidity inside the equipment, thus affecting the normal operation of the equipment; when the condensate flows towards important parts inside the unit, such as compressors, wires, etc., it will cause ice blockage and vibration cracking, posing safety hazards such as motor short - circuit. Content of the Utility Model

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. For this purpose, the utility model provides an evaporator base and a heat pump, which can quickly discharge condensate, prevent the fins of the evaporator main body from being frozen, and avoid the evaporator main body from frequently entering the defrosting mode.

[0004] The solution of the utility model to solve its technical problems is as follows:

[0005] An evaporator base includes a base main body and an auxiliary heater; the base main body is provided with an installation groove for assembling the evaporator main body, the opening of the installation groove faces upwards and is open, the auxiliary heater is arranged in the installation groove, and the bottom surface of the installation groove is provided with a plurality of drain holes.

[0006] This technical solution has at least the following beneficial effects: The evaporator main body is assembled in the installation groove, and the installation groove wraps the bottom of the evaporator main body. The condensate generated by the evaporator main body flows towards the bottom of the installation groove under the action of gravity and is discharged from the drain holes opened at the bottom of the installation groove; moreover, an auxiliary heater is arranged between the installation groove and the bottom of the evaporator main body to improve the defrosting efficiency of the evaporator main body. At the same time, the auxiliary heater can keep the installation groove in a relatively high - temperature environment, which can effectively prevent the condensate from freezing the evaporator main body and causing the evaporator main body to frequently enter the defrosting mode. The channel formed by the cooperation of the evaporator main body and the installation groove can maximize the flow of the heat generated by the auxiliary heater to the evaporator main body, making the defrosting of the evaporator main body more efficient.

[0007] As a further improvement of the above technical solution, the bottom support body has a rectangular disc-shaped structure. An L-shaped baffle is provided on the groove bottom surface of the bottom support body. Two side walls of the baffle are parallel to two adjacent inner walls of the bottom support body, and together form the L-shaped installation groove.

[0008] The overall bottom support body has a rectangular disc-shaped structure. Four inner walls of the bottom support body and the groove bottom surface of the bottom support body together form a disc cavity for receiving the condensed water generated by the evaporator body. The L-shaped baffle forms an installation groove matching the shape of the bottom of the evaporator body with two adjacent inner walls of the bottom support body, making full use of the inner walls of the bottom support body, which helps to simplify the sheet metal manufacturing process, reduce the number of baffles, is beneficial to cost savings, and also enables the evaporator body to be installed at the edge position of the bottom support body, increasing the available space of the bottom support body. Therefore, other larger-sized accessories and components can be selected for the bottom support body.

[0009] As a further improvement of the above technical solution, the baffle includes a first plate and a second plate; the first plate stands on the groove bottom surface of the bottom support body, the lower end of the second plate is connected to the upper end of the first plate, and the upper end of the second plate inclines towards the outside of the installation groove.

[0010] The second plate arranged obliquely can increase the assembly entrance of the evaporator body, facilitating assembly; moreover, the inclined second plate can act as a guiding plate to guide the evaporator body into the installation groove, thereby reducing the assembly difficulty and improving the assembly efficiency.

[0011] As a further improvement of the above technical solution, at least two brackets for connecting with the evaporator body are provided in the installation groove, and the height of the brackets is lower than the height of the installation groove.

[0012] At least two brackets can stably support the evaporator body, making the load of the evaporator body evenly distributed on all brackets; setting the brackets is beneficial to increasing the distance between the bottom of the evaporator body and the groove bottom surface of the installation groove, so that there is enough space for the condensed water to drain. When there is a large amount of condensed water generated by the evaporator body, if the distance is small, it will directly affect the drainage efficiency, and then cause the condensed water to repeatedly freeze the fins of the evaporator body, or cause the condensed water to flow into the equipment interior, affecting the normal operation of the equipment. The height of the brackets is lower than the height of the installation groove to prevent the condensed water from flowing to areas outside the installation groove.

[0013] As a further improvement of the above technical solution, the bracket has an L-shaped structure, one end is fixedly connected to the groove bottom surface of the installation groove, the other end is connected to the side wall surface of the installation groove, and the top surface of the bracket is parallel to the groove bottom surface of the installation groove.

[0014] The bracket is in an L-shaped structure. One end of the bracket is fixedly connected to the baffle plate forming the installation groove, and the other end is fixedly connected to the bottom surface of the installation groove, forming a stable structure that can support the evaporator body.

[0015] As a further improvement of the above technical solution, the auxiliary heater is an electric auxiliary heating belt, and the bottom surface of the installation groove is provided with installation buckles for fixing the electric auxiliary heating belt.

[0016] The electric auxiliary heating belt is small in volume, has good flexibility, and has a relatively simple structure. It is very convenient for design and installation, and easy to maintain. Moreover, the electric auxiliary heating belt has a relatively high thermal efficiency, can heat evenly, and can also save energy. The installation buckles can fix the electric auxiliary heating belt at a preset position, preventing the electric auxiliary heating belt from blocking the drain hole and affecting the drainage efficiency of the condensed water.

[0017] As a further improvement of the above technical solution, the bottom of the bottom bracket body is provided with installation feet for assembly.

[0018] Setting the installation feet can fix the bottom bracket body at a preset position and improve the stability of the bottom bracket body at the same time.

[0019] As a further improvement of the above technical solution, the installation feet include a first installation bottom foot and a second installation bottom foot that are parallel to each other; both the bottom of the first installation bottom foot and the second installation bottom foot are provided with installation holes for assembly; a reinforcing rib is provided between the first installation bottom foot and the second installation bottom foot.

[0020] The reinforcing rib can strengthen the strength and compressive performance of the bottom bracket body without increasing the thickness of the bottom bracket body, preventing the bottom bracket body from deforming.

[0021] A heat pump includes the above-mentioned evaporator bottom bracket.

[0022] Using the above-mentioned evaporator bottom bracket, the condensed water in the heat pump can be quickly and efficiently discharged, preventing the condensed water from seeping into the accessories of the heat pump.

[0023] As a further improvement of the above technical solution, the heat pump further includes a middle water tray, and the top of the middle water tray is provided with an inclined surface; the bottom bracket body is arranged on the inclined surface, and the drain hole is located at the lower end of the inclined surface.

[0024] The bottom bracket body is arranged on the inclined surface of the middle water tray, and the drain hole is located at the lower end of the inclined surface, so that the condensed water flows along the inclined bottom bracket body to the drain hole under the action of gravity, accelerating the discharge of the condensed water and preventing other positions of the bottom bracket body from accumulating water.

[0025] Other features and advantages of the present invention will be described in the subsequent specification, and some of them will become obvious from the specification or be understood by implementing the present invention. Brief Description of the Drawings

[0038] Next, the technical solution of the present utility model will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the following described embodiments are some embodiments of the present utility model, not all embodiments.

[0039] As Figure 1 、 Figure 2 and Figure 5 shown, an evaporator bottom bracket includes a bottom bracket main body 2 and an auxiliary heater; the bottom bracket main body 2 has a rectangular disc-like structure and is used to hold the condensed water generated by the evaporator main body 6 to prevent the condensed water from flowing towards the important parts inside the unit. The bottom bracket main body 2 is provided with an installation groove 3 for assembling the evaporator main body 6, and the opening of the installation groove 3 faces upward and is open. A baffle 1 is provided on the groove bottom surface of the bottom bracket main body 2. Specifically, the baffle 1 is L-shaped, and the two side walls of the baffle 1 are parallel to the two adjacent inner walls of the bottom bracket main body 2, so that the baffle 1 and the two adjacent inner walls of the bottom bracket main body 2 jointly form an L-shaped installation groove 3. The auxiliary heater is arranged in the installation groove 3. Specifically, the auxiliary heater is an electric auxiliary heating belt. In addition, the auxiliary heater can also be a heating element such as a heating pipe. An installation buckle for fixing the electric auxiliary heating belt is provided at the bottom of the installation groove 3. A plurality of drain holes 31 are provided on the groove bottom surface of the installation groove 3.

[0040] The evaporator main body 6 is assembled in the installation groove 3, and the installation groove 3 wraps the bottom of the evaporator main body 6. The generated condensed water flows centrally towards the bottom of the installation groove 3 under the action of gravity and is discharged through the drain holes 31 opened at the bottom of the installation groove 3; after the evaporator main body 6 is assembled in the installation groove 3, an auxiliary heater is added between the installation groove 3 and the bottom of the evaporator main body 6 to improve the defrosting efficiency of the evaporator main body 6. At the same time, the auxiliary heater can keep the installation groove 3 in a relatively high-temperature environment, which can effectively prevent the condensed water from freezing the evaporator main body 6 and causing the evaporator main body 6 to frequently enter the defrosting mode. The channel formed by the cooperation of the evaporator main body 6 and the installation groove 3 can maximize the heat generated by the auxiliary heater flowing towards the evaporator main body 6, making the defrosting of the evaporator main body 6 more efficient.

[0041] The baffle 1 with an L-shaped structure and two adjacent inner walls of the base support body 2 form a mounting groove 3 that matches the shape of the bottom of the evaporator body 6, making full use of the inner walls of the base support body 2, which helps to simplify the sheet metal manufacturing process, reduce the number of baffles 1, save costs, and also enables the evaporator body 6 to be installed at the edge position of the base support body 2, increasing the available space of the base support body 2. Therefore, the base support body 2 can be equipped with other accessories and components with larger volumes.

[0042] The electric auxiliary heating belt is small in volume, has good flexibility, and a relatively simple structure. Its design and installation are very convenient, and maintenance is simple. Moreover, the electric auxiliary heating belt has a relatively high heating efficiency, can heat evenly, and can also save energy. The installation buckle can fix the electric auxiliary heating belt in a preset position to prevent the electric auxiliary heating belt from blocking the drain hole and affecting the drainage efficiency of the condensed water. Since a blower will also be assembled on the base support body 2, and the blower will generate vibration during operation. If the installation buckle is not added, when the vibration is transmitted to the base support body 2, it will vibrate the electric auxiliary heating belt out of the preset position, unable to ensure that it heats at the correct position.

[0043] In order to obtain higher heat, the electric auxiliary heating belt is arranged in the form of a meandering structure on the bottom surface of the mounting groove 3, fixed in the preset position by the installation buckle, and avoiding the drain hole 31. By increasing the laying area of the electric auxiliary heating belt, the generation of heat is increased. The electric auxiliary heating belt is assembled at the bottom of the mounting groove 3 and is located between the bottom surface of the mounting groove 3 and the bottom surface of the evaporator body 6. Under the action of the mounting groove 3, part of the heat generated by the electric auxiliary heating belt is concentrated and transferred to the bottom surface of the evaporator body 6 along the wall surface of the mounting groove 3, improving the transfer efficiency of the heat of the electric auxiliary heating belt to the evaporator body 6 and making the most of the heat generated by the electric auxiliary heating belt.

[0044] In another embodiment, the evaporator base support includes a base support body 2 and an auxiliary heater; the base support body 2 has a rectangular flat plate structure and is used to hold the condensed water generated by the evaporator body 6 to prevent the condensed water from flowing towards the important parts inside the unit. The base support body 2 is provided with a mounting groove 3 for assembling the evaporator body 6, and the opening of the mounting groove 3 faces upwards and is open. Since the condensed water generated by the evaporator body 6 flows out from the bottom of the evaporator body 6, the mounting groove 3 can be composed of two parallel baffles 1, and the area formed between the two baffles 1 is the mounting groove 3. In the specific implementation process, the evaporator body 6 is installed in the mounting groove 3 composed of the two baffles 1, and almost all the condensed water flows into the mounting groove 3. At this time, the base support body 2 can be a plate-like structure. Compared with setting the base support body 2 as a rectangular disk-like structure, the sheet metal of the four side walls is saved, reducing the cost. The drain hole 31 is still arranged at the bottom of the mounting groove 3. It should be noted that the mounting groove 3 can be adjusted according to the shape of the evaporator body 6.

[0045] In another embodiment, as Figure 6As shown, in this embodiment, the evaporator base support includes a base support body 2 and an auxiliary heater; the base support body 2 is in a rectangular flat plate structure, which is used to hold the condensed water generated by the evaporator body 6 to prevent the condensed water from flowing towards the important parts inside the unit. The base support body 2 is provided with a mounting groove 3 for assembling the evaporator body 6, and the opening of the mounting groove 3 faces upwards and is open. The baffle 1 includes a first plate 11 and a second plate 12; specifically, the first plate 11 is vertically standing at the lower end of the bottom surface of the base support body 2 and is fixedly connected to the base support body 2 by welding; the lower end of the second plate 12 is connected to the top end of the first plate 11, and the upper end of the second plate 12 is inclined towards the outside of the mounting groove 3. The outwardly inclined second plate 12 makes the opening of the mounting groove 3 larger. For installing the evaporator body 6, a larger opening can more easily align with the slot opening, reducing the difficulty of alignment. At the same time, the inclined second plate 12 can also serve as a guide plate to guide the evaporator body 6 into the mounting groove 3 when installing the evaporator body 6.

[0046] In order to obtain a larger drainage space, in this embodiment, it includes a base support body 2 and an auxiliary heater; the base support body 2 is in a rectangular flat plate structure, which is used to hold the condensed water generated by the evaporator body 6 to prevent the condensed water from flowing towards the important parts inside the unit. The base support body 2 is provided with a mounting groove 3 for assembling the evaporator body 6, and the opening of the mounting groove 3 faces upwards and is open. At least two brackets 4 are provided in the mounting groove 3. Specifically, the height of the bracket 4 is lower than the top surface of the mounting groove 3; the bracket 4 is in an L-shaped structure, one end is fixedly connected to the bottom of the base support body 2, and the other end is connected to the side surface of the baffle 1. The top surface of the bracket 4 is parallel to the bottom surface of the base support body 2. At least two brackets 4 can stably support the evaporator body 6, so that the load of the evaporator body 6 is evenly distributed on all brackets 4; setting the brackets 4 is beneficial to raising the distance between the bottom of the evaporator body 6 and the bottom surface of the mounting groove 3 of the base support body 2, so that there is enough space for the condensed water to drain. When there is a large amount of condensed water generated by the evaporator body 6, if the distance is small, it will directly affect the drainage efficiency, which will in turn cause the condensed water to repeatedly freeze the fins of the evaporator body 6, or cause the condensed water to flow towards the inside of the equipment, affecting the normal operation of the equipment. The height of the bracket 4 is lower than the height of the mounting groove 3 to prevent the condensed water from flowing to areas outside the mounting groove 3.

[0047] As Figures 3 - 4As shown, in this embodiment, mounting feet 5 for assembly are provided at the bottom of the base support body 2. Specifically, the mounting feet 5 include a first mounting base foot 51 and a second mounting base foot 52 that are parallel to each other; mounting holes for assembly are provided at the bottoms of both the first mounting base foot 51 and the second mounting base foot 52; and a reinforcing rib 53 is provided between the first mounting base foot 51 and the second mounting base foot 52. The mounting feet 5 are used to fix the base support body 2 on the air source heat pump unit. The mounting feet 5 include a first mounting base foot 51 and a second mounting base foot 52 that are parallel to each other; mounting holes for assembly are provided at the bottoms of both the first mounting base foot 51 and the second mounting base foot 52.

[0048] In this embodiment, the two mutually parallel first mounting base feet 51 and second mounting base feet 52 are identical in shape and length, and can be structures with relatively high stability such as square hollow steel pipes. The first mounting base foot 51 and the second mounting base foot 52 are fixed to the bottom of the base support body 2 and can be connected to the base support body 2 by means such as welding or riveting. Mounting holes are provided at the bottoms of the first mounting base foot 51 and the second mounting base foot 52 for assembly with other parts of the unit. The first mounting base foot 51 and the second mounting base foot 52 can be one group or multiple groups, which can evenly distribute the weight of the base support body 2 on the first mounting base foot 51 and the second mounting base foot 52. The reinforcing rib 53 can strengthen the strength and compressive performance of the base support body 2 without increasing the thickness of the base support body 2, and prevent the base support body 2 from deforming. The bracket 4 is in an L-shaped structure. One end of the bracket 4 is fixedly connected to the baffle 1 forming the mounting groove 3, and the other end is fixedly connected to the bottom surface of the base support body 2, forming a stable structure to support the evaporator body 6.

[0049] This embodiment also provides a heat pump, which includes any one of the evaporator bases in the above embodiments, and further includes a medium water tray 7 for covering the top of the heat pump chassis, as Figure 7 shown. An inclined surface 71 for mounting the base support body 2 is provided at the top of the medium water tray 7; during installation, the drain hole 31 is located at the lower end of the inclined surface 71. The base support body 2 is on the inclined surface 71 of the medium water tray 7, and the drain hole 31 is located at the lower end of the inclined surface 71, so that the condensed water flows along the inclined base support body 2 and concentrates towards the drain hole 31 under the action of gravity, avoiding water accumulation at other positions of the base support body 2.

[0050] The above has described the embodiments of the present invention in detail with reference to the drawings. However, the present invention is not limited to the above embodiments. Various changes can be made without departing from the spirit of the present invention within the knowledge of those of ordinary skill in the art.
