For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0041] In view of the problem that when the drain hole of the existing heat pump water heater is blocked, the condensed water cannot be discharged in time, causing the electric control system to malfunction, the utility model provides a water pan and heat pump water heater.
[0042] The embodiments of the utility model will be described below in combination with Figures 1 to 10
[0043] According to the embodiments of the utility model, on the one hand, as Figures 1 to 9 indicated, a water pan for a heat pump water heater comprises a disc body 1 and an annular flange 2 surrounding the disc body 1, the disc body 1 is provided with a drain hole 101, the side of the annular flange 2 close to the drain hole 101 is provided with an overflow port 201, and the position of the overflow port 201 is higher than that of the drain hole 101.
[0044] It should be noted that during the operation of the heat pump water heater, condensed water is generally formed around the evaporator, fan, evaporator inlet pipe and compressor return pipe inside the heat pump water heater, so the heat pump water heater is generally provided with a water pan capable of collecting the above-mentioned condensed water, so as to avoid the random flow of the condensed water in the heat pump water heater and reduce the circuit short circuit, component corrosion and other situations caused by the random flow of the condensed water inside the heat pump water heater. Further, in order to ensure that the condensed water can be completely collected by the water pan, the water pan is generally arranged directly below the above-mentioned equipment capable of producing condensed water. However, although the water pan can collect the condensed water, the condensed water in the water pan will continue to accumulate over time, so the distance between the water level in the water pan and the electrical equipment such as the fan above the water pan will continue to decrease, which is prone to electrical safety accidents.
[0045] Based on this, the present embodiment is provided with the drain hole 101 on the disc body 1, so that the condensed water collected on the disc body 1 can be discharged in time, avoiding water accumulation on the disc body 1. However, if the drain hole 101 is blocked, the drainage speed will slow down, and the condensed water will accumulate on the disc body 1. In order to prevent the water level in the disc body 1 from being too high to contact the electrical elements on the disc body 1, the present embodiment sets the overflow port 201 at a position higher than the drain hole 101, so that the condensed water accumulated to a certain height can be discharged to the outside of the heat pump water heater in time, ensuring the safety of the electrical elements.
[0046] In addition, the existence of the annular flange 2 can also isolate the disc body 1 from the external environment, preventing water vapor, dust in the external environment from contacting the disc body 1. In addition, by setting the annular flange 2, the peripheral outer surface of the water pan can be matched with the outer surface of the heat pump water heater.
[0047] In addition, to ensure that all the condensed water can be collected by the water pan, the size of the water pan can be relatively large. In an example, the evaporator, the fan, the evaporator inlet pipe and the compressor return pipe are projected onto the water pan body 1.
[0048] In an embodiment, as shown in Figure 5 and Figure 6 , the bottom surface of the overflow port 201 is inclined downwardly away from the upper surface 102 of the water pan body 1. The downward inclination of the bottom surface of the overflow port 201 can accelerate the flow of the condensed water, avoid the water level in the water pan body 1 rising rapidly due to slow water flow, and prevent the electrical safety problems caused by excessive water contacting the electrical elements above the water pan.
[0049] In an embodiment, as shown in Figure 1 and Figure 8 , the upper surface 102 of the water pan body 1 is provided with the evaporator drainage groove 103 and the fan drainage groove 104 in communication, and the drainage hole 101 is located in the evaporator drainage groove 103 and penetrates the bottom surface of the evaporator drainage groove 103. The evaporator drainage groove 103 and the fan drainage groove 104 can collect and guide the condensed water generated by the evaporator and the fan respectively, so that the collection of the condensed water is more orderly and planned.
[0050] It should be noted that the fan in the heat pump water heater generally only generates condensed water under extreme working conditions, so compared with the evaporator, the fan generates relatively less condensed water during the operation of the heat pump water heater. In the same time, the evaporator drainage groove 103 is more likely to accumulate condensed water. Therefore, the present embodiment sets the drainage hole 101 in the evaporator drainage groove 103, which can accelerate the discharge speed of the condensed water in the evaporator drainage groove 103 and avoid water accumulation.
[0051] In an embodiment, as shown in Figures 2 to 4As shown, the depth of the evaporator drainage groove 103 is greater than that of the fan drainage groove 104, and the communication between the fan drainage groove 104 and the evaporator drainage groove 103 forms a step 105. The deeper evaporator drainage groove 103 can increase the temporary water storage capacity of the evaporator drainage groove 103, avoiding the direct overflow of the condensate from the evaporator drainage groove 103 due to the drainage speed of the drainage hole 101 being less than the generation speed of the condensate. The relatively shallow fan drainage groove 104 can not only be adapted to the characteristics of the fan generating a small amount of condensate, but also reduce the occupation of the installation space. Further, by setting the step 105 at the communication between the fan drainage groove 104 and the evaporator drainage groove 103, on the one hand, the condensate in the fan drainage groove 104 can flow smoothly into the evaporator drainage groove 103, and then be discharged through the drainage hole 101 located at the bottom surface of the evaporator drainage groove 103; on the other hand, the condensate in the evaporator drainage groove 103 can be prevented from flowing back into the fan drainage groove 104, ensuring that the fan and its surrounding components are not affected by the condensate.
[0052] In one embodiment, as shown in Figure 5 and Figure 6 the inlet of the overflow port 201 is connected with the upper surface 102 of the step 105. In this way, the condensate can flow naturally from the upper surface 102 of the step 105 to the overflow port 201, ensuring that the condensate can be orderly gathered at the overflow port 201 in the case that the drainage of the drainage hole 101 is blocked and the condensate accumulates. Preferably, the inlet of the overflow port 201 is lower than the upper surface 102 of the step 105.
[0053] In one embodiment, as shown in Figure 1 and Figure 8 the upper surface 102 of the disc body 1 is further provided with a pipeline drainage groove 106 communicating with the evaporator drainage groove 103, and the pipeline drainage groove 106, the evaporator drainage groove 103 and the fan drainage groove 104 are arranged in sequence along the radial direction of the disc body 1, and the drainage hole 101 is arranged at the intersection of the three. It should be noted that during the operation of the heat pump water heater, the evaporator in the heat pump water heater needs to exchange heat with the external environment, such as air, to obtain heat for subsequent heating of hot water. In order to ensure that the evaporator can absorb sufficient heat from the air, it is necessary to ensure that the airflow uniformly contacts each part of the evaporator, so that the evaporator has a high heat exchange efficiency. Based on this, the fan for providing flowing air in the heat pump water heater is arranged side by side with the evaporator, which can make each part of the evaporator uniformly contact the airflow and improve the heat exchange efficiency. Therefore, in the present embodiment, the pipeline drainage groove 106, the evaporator drainage groove 103 and the fan drainage groove 104 are arranged in sequence along the radial direction of the disc body 1, which not only can be adapted to the layout of the evaporator and the fan, but also can facilitate the accurate collection of the condensate generated by the pipeline, the evaporator and the fan.
[0054] In one embodiment, as shown in Figure 1 and Figure 8 The upper surface 102 of the disc body 1 is further provided with a baffle 3 located at the junction of the evaporator drainage groove 103 and the pipeline drainage groove 106. A gap 4 is left between the baffle 3 and the annular flange 2 along the extension direction of the baffle 3, and the evaporator drainage groove 103 is connected to the pipeline drainage groove 106 through the gap 4.
[0055] Since the evaporator leaves a gap 4 with the upper surface 102 of the disc body 1 in the assembled state, when the fan blows air towards the evaporator, part of the airflow will flow through the gap 4 between the evaporator and the disc body 1, thereby causing the evaporator to fail to exchange heat with all the airflow. Based on this, the present embodiment sets a baffle 3 on the disc body 1, which can make the airflow blown by the fan concentrate as much as possible in the main heat exchange area of the evaporator, so that the evaporator can exchange heat with more airflow fully and efficiently, thereby improving the heat exchange efficiency of the evaporator. Further, the baffle 3 is arranged at the junction of the evaporator drainage groove 103 and the pipeline drainage groove 106, which can optimize the structural layout of the upper surface 102 of the disc body 1 and avoid the baffle 3 occupying the installation space of other structures on the disc body 1. Secondly, the gap 4 left between the baffle 3 and the annular flange 2 can make the condensed water in the pipeline drainage groove 106 flow smoothly into the evaporator drainage groove 103 and be discharged to the outside of the heat pump water heater through the drainage hole 101.
[0056] In one embodiment, as shown in Figures 2 to 4 The bottom surface of the evaporator drainage groove 103 includes a first bottom surface 1031 and a second bottom surface 1032 connected to the first bottom surface 1031, and the drainage hole 101 is arranged at the connection between the two. The first bottom surface 1031 and the second bottom surface 1032 are arranged in a tilted manner towards the direction where the drainage hole 101 is located. In this way, the condensed water in the evaporator drainage groove 103 can be quickly gathered towards the drainage hole 101, avoiding the accumulation of condensed water in the evaporator drainage groove 103 and improving the drainage efficiency.
[0057] In one embodiment, as shown in Figure 4 and Figure 9 The inclination angle of the first bottom surface 1031 and the second bottom surface 1032 near the drainage hole 101 is greater than the inclination angle of the two away from the drainage hole 101. A larger inclination angle near the drainage hole 101 can accelerate the flow of condensed water to the drainage hole 101, shorten the time required for drainage, and reduce the possibility of accumulation of condensed water in the drainage groove. A smaller inclination angle away from the drainage hole 101 can make the evaporator drainage groove 103 have a relatively large slot, increasing the temporary water storage capacity of the evaporator drainage groove 103.
[0058] According to the embodiments of the present application, on the other hand, asFigure 10 The heat pump water heater also comprises a main machine, the water receiving tray and a water tank 5.
[0059] The heat pump water heater with the water receiving tray can quickly drain the condensed water, and reduce the possibility of safety accidents.
[0060] It should be noted that the main machine in the embodiment is internally provided with, but not limited to, core components such as a compressor, a condenser, a fan, an evaporator and an electric control system.
[0061] In the specific contents of the above specific embodiments, any non-contradictory combination of technical features can be combined, and in order to make the description simple, all possible combinations of the above technical features are not described, however, as long as the combination of these technical features does not exist, it should be considered as the scope of the description.
[0062] The specific contents of the above specific embodiments only express several embodiments of the utility model, the description is more specific and detailed, but it cannot be understood as the limitation of the patent scope of the utility model. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
