Description

Technical Field

[0001] The utility model relates to the technical field of heat supply pump groups, and in particular to an intelligent heat supply pump group. Background Art

[0002] The smart heat pump group is a key equipment in the modern heating system. It integrates advanced automation and intelligent technologies to achieve high efficiency, energy saving and intelligent management of the heating system. The equipment that provides heating is mostly air source heat pump.

[0003] Air source heat pumps generally use a compressor to compress the inhaled air to achieve the effect of heat exchange. However, in winter, due to the lower air temperature, the speed at which the compressed air generates heat is reduced, requiring the compressor inside the pump to speed up in order to achieve the effect of rapid heating. However, accelerating the compressor will cause the compressor to wear quickly, thereby reducing the service life of the heating pump unit. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in winter, due to the low air temperature, the speed of compressed air generating heat is reduced, so the compressor inside the pump needs to be accelerated to achieve the effect of rapid heating. However, accelerating the rotation of the compressor will cause rapid wear of the compressor and thus reduce the service life of the heating pump group. Therefore, an intelligent heating pump group is proposed.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a smart heat pump group, including a body, a fan is provided at the top of the body, an evaporator, a compressor and a condenser are provided inside the body, a water inlet pipe and a water outlet pipe are provided on both sides of the body respectively, a heating device is provided at the top of the body, the heating device includes a rectangular frame, a temperature sensor is provided on one side of the rectangular frame, the bottom end of the rectangular frame is fixedly connected to the top of the body, the outer surface of the rectangular frame is fixedly connected to the insulation plate, the inner wall of the rectangular frame is rotatably connected to a plurality of rotating shafts, the outer surface of the rotating shaft is fixedly connected to the heat conducting plate, the outer surface of the heat conducting plate is provided with two rectangular grooves, the inner wall of the rectangular frame is provided with an electric heating rod, the outer surface portion of the electric heating rod is located at the rectangular groove on the outer surface of the heat conducting plate, an electric telescopic rod is provided on one side of the rectangular frame, the output rod of the electric telescopic rod is fixedly connected to a sliding rod, one side of the sliding rod slides on one side of the insulation plate, the top of the heat conducting plate is fixedly connected to a blocking rod, and the top of the sliding rod is fixedly connected to a plurality of push rods.

[0006] The effects achieved by the above components are as follows: by setting up a rectangular frame, when the heat pump group is working, cold water enters the body through the pipe on one side of the body, the air is sucked into the body through the fan, and the heat energy in the air is absorbed by the evaporator. At the same time, the compressor inside the body sucks in the low-temperature medium and compresses it into high-temperature and high-pressure gas, which then enters the condenser to produce hot water and outputs it through the pipe on the other side of the body for heating. In low-temperature weather, when the ambient temperature is low as detected by the sensor on one side of the rectangular frame, the electric heating rod is operated to heat up for a period of time, and the heat on the surface of the electric heating rod is transferred to the outer surface of each heat-conducting plate, so that the temperature inside the rectangular frame is increased, and the heat insulation on the outside is used to heat the inside of the rectangular frame. The plate is insulated, and at the same time, the electric telescopic rod is extended to push the sliding rod to slide on one side of the machine body. The push rod at the top of the sliding rod pushes the baffle rod at the top of the heat conduction plate to control the heat conduction plate to rotate and tilt away from the electric telescopic rod through the rotating shaft. When the rotating shaft drives the heat conduction plate to rotate, the rectangular groove on the outer surface of the heat conduction plate will move on the outer surface of the electric heating rod. By tilting the heat conduction plate, the gap between the heat conduction plate and the top of the rectangular frame is reduced, and the dissipation rate of hot air inside the rectangular frame is slowed down. When the air passes through the inside of the rectangular frame and enters the fan, the temperature will be higher than the ambient temperature, so that the compressor does not need to accelerate to heat quickly, thereby improving the service life of the compressor and the heat pump group.

[0007] Preferably, the heat conducting plate is made of metal aluminum, and the rotating shaft is made of metal iron.

[0008] The effect achieved by the above components is: by setting the heat conduction plate to be made of metal aluminum, the heat of the electric heating rod can be transferred to the outer surface of the heat conduction plate more quickly and comprehensively, and the rotating shaft made of metal iron makes the heat on the surface of the heat conduction plate dissipate from the surface of the rotating shaft to the rectangular frame at a slower rate.

[0009] Preferably, one side of the baffle rod is fixedly connected to an oblique rod, and one end of the oblique rod away from the baffle rod is fixedly connected to one side of the heat conducting plate.

[0010] The effect achieved by the above components is: by arranging the oblique rods, the connection between the baffle rod and the heat conducting plate can be reinforced, thereby improving the structural stability of the connection between the baffle rod and the heat conducting plate.

[0011] Preferably, a heat preservation strip is fixedly connected to the top end of the heat conducting plate, and the heat preservation strip is wrapped around the top edge of the heat conducting plate.

[0012] The effect achieved by the above components is: by providing the insulation strips, the heat on the surface of the heat conducting plate can be further blocked, and the rate at which the heat on the surface of the heat conducting plate is dissipated through the top of the heat conducting plate can be reduced as much as possible.

[0013] Preferably, several reset devices are provided at the top of the sliding rod, and the reset device includes a rectangular rod and a vertical rod. A spring is provided on one side of the rectangular rod, and the two ends of the spring are fixedly connected to one side of the rectangular rod and one side of the vertical rod respectively. One side of the vertical rod is fixedly connected to one side of the insulation board. The bottom end of the rectangular rod is fixedly connected with a slider, and a sliding groove is provided at the top of the sliding rod. The outer surface of the slider is slidably connected to the inner wall of the sliding groove.

[0014] The effect achieved by the above components is: when the electric telescopic rod extends and pushes the sliding rod to move, one side of the barrier rod will contact one side of the rectangular rod, pushing the slider at the bottom end of the rectangular rod to slide along the inner wall of the slide groove toward the direction of the vertical rod and compress the spring. When the electric telescopic rod contracts and pulls the sliding rod and the push rod back, the spring will return to its original shape and push the rectangular rod to move in the original direction, pushing the barrier rod through the rectangular rod to rotate the heat conduction plate back to its original position.

[0015] Preferably, a round rod is fixedly connected to one side of the rectangular rod, and the outer surface of the round rod slides on the inner wall of the vertical rod.

[0016] The effect achieved by the above components is that when the rectangular rod moves, the round rod will slide on the inner wall of the vertical rod. The round rod can further limit the angle between the rectangular rod and the vertical rod, thereby avoiding the angle of the rectangular rod from deflecting as much as possible.

[0017] Preferably, the inner diameter of the spring is slightly larger than the diameter of the round rod, and the round rod is located inside the spring.

[0018] The effect achieved by the above components is that when the rectangular rod moves to deform the spring, the spring will move outside the round rod. The round rod can reinforce the internal shape of the spring, thereby avoiding spring distortion and affecting normal use as much as possible.

[0019] Preferably, the top end of the rectangular rod is fixedly connected to a positioning rod, and one end of the positioning rod away from the rectangular rod slides on the top end of the vertical rod.

[0020] The effect achieved by the above components is that when the rectangular rod moves, the end of the positioning rod away from the rectangular rod will slide on the top of the vertical rod. The positioning rod can further limit the angle between the rectangular rod and the vertical rod, further preventing the rectangular rod from shaking when moving.

[0021] Compared with the prior art, the advantages and positive effects of the present invention are:

[0022] In the utility model, a heating device is provided. In low temperature weather, the heat conducting plate is heated and heated by the electric heating rod, and the heat conducting plate is tilted to reduce the gap between the heat conducting plate and the top of the rectangular frame, thereby slowing down the rate of heat dissipation inside the rectangular frame. When the air passes through the rectangular frame and enters the fan, the temperature will be higher than the ambient temperature, so that the compressor does not need to accelerate to quickly heat up, thereby improving the service life of the compressor and the heat pump group.

There are two rectangular grooves 27, an electric heating rod 25 is provided on the inner wall of the rectangular frame 21, and the outer surface portion of the electric heating rod 25 is located at the rectangular groove 27 on the outer surface of the heat conducting plate 24. An electric telescopic rod 28 is provided on one side of the rectangular frame 21, and the output rod of the electric telescopic rod 28 is fixedly connected to a sliding rod 29.

The top of the heat conducting plate 24 is fixedly connected to a blocking rod 210, and the top of the sliding rod 29 is fixedly connected to a plurality of push rods 211. By setting the rectangular frame 21, when the heat pump group is working, cold water enters the interior of the body 1 through the pipe on one side of the body 1, and air is sucked into the body 1 through the fan 5. Inside, the evaporator 4 absorbs heat energy from the air, while the compressor inside the body 1 sucks in the low-temperature medium and compresses it into high-temperature and high-pressure gas, which then enters the condenser to produce hot water and outputs it through the pipe on the other side of the body 1 for heating. In low-temperature weather, when the sensor on one side of the rectangular frame 21 detects that the ambient temperature is low, the electric heating rod 25 is operated to heat and heat for a period of time, and the heat on the surface of the electric heating rod 25 is transferred to the outer surface of each heat conducting plate 24, so that the temperature inside the rectangular frame 21 is increased, and the heat is kept warm by the outer insulation plate 22.

When the rotating shaft 23 drives the heat conducting plate 24 to rotate, the rectangular groove 27 on the outer surface of the heat conducting plate 24 will move on the outer surface of the electric heating rod 25. By tilting the heat conducting plate 24, the gap between the heat conducting plate 24 and the top of the rectangular frame 21 is reduced, and the heat dissipation rate of the inside of the rectangular frame 21 is slowed down. When the air passes through the inside of the rectangular frame 21 and enters the fan 5, the temperature will be higher than the ambient temperature, so that the compressor does not need to accelerate to heat quickly, thereby improving the service life of the compressor and the heat pump unit.
