Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a refrigerant circulation system and an air conditioner. Background Art

[0002] The electronic expansion valve is a throttling valve that plays a role in throttling and reducing pressure in the refrigeration system and is the core component of air conditioning equipment. The electronic expansion valve consists of a stepper motor coil and a valve body with a magnetic rotor. Its working principle is: the electronic controller sends a drive signal to rotate the rotor of the stepper motor, and through the transmission of the thread, the rotational motion of the rotor is converted into the axial motion of the valve needle. The valve port flow area is adjusted by the different positions of the valve needle, thereby playing a role in regulating the refrigerant flow in the system.

[0003] Since the electronic expansion valve body and motor coil are heavy, the inlet and outlet pipes connected to the electronic expansion valve are relatively small. When the system is running, the electronic expansion valve will vibrate violently due to the large change in pipe diameter and fast flow. If it is not fixed properly, the pipe connected to the electronic expansion valve will be easily broken by vibration, thus affecting the reliability of the entire air conditioning unit.

[0004] At present, the industry's main approach to fixing the electronic expansion valve is to add pipe clamps to the connecting pipes at both ends of the electronic expansion valve and fix them on the bracket. Since the weight of the electronic expansion valve is mainly concentrated on the valve body and the motor coil, if only the connecting pipes at both ends of the electronic expansion valve are fixed, the electronic expansion valve will vibrate greatly and the pipes will break easily, which reduces the reliability of the electronic expansion valve.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The refrigerant circulation system of household appliances such as air conditioners, refrigerators and air-energy water heaters includes a compressor for compressing refrigerant, a condenser for condensing the compressed refrigerant, an evaporator in which the condensed refrigerant evaporates, and a throttle valve disposed between the condenser and the evaporator. Optionally, the throttle valve includes an electronic expansion valve.

[0032] Figure 1 A schematic structural diagram of a throttle valve fixing assembly of a refrigerant circulation system of this embodiment is shown. Figure 2 Shows Figure 1 An exploded view of the throttle valve mounting assembly is shown.

[0033] like Figure 1 and 2 As shown, the throttle valve includes a valve body 2 and a refrigerant pipe 3 connected to the valve body 2. The throttle valve also includes a motor 1 for driving the valve core of the valve body 2 to move so as to change the opening of the valve body 2. Optionally, the motor 1 includes a stepping motor.

[0034] The refrigerant circulation system further comprises a retaining portion for mounting and fixing the throttle valve, and the retaining portion comprises an elastic component 5 for slowing down the vibration of the throttle valve. The elastic component 5 can slow down the vibration of the throttle valve, thereby improving the problem in the prior art that the throttle valve is easily damaged by vibration.

[0035] Figure 3 FIG. 1 is a schematic diagram showing a three-dimensional structure of the elastic component 5 of this embodiment. Figure 4 FIG. 1 is a schematic diagram showing the top structure of the elastic component 5 of this embodiment.

[0036] Combination Figures 1 to 4 As shown, the elastic component 5 includes a mounting cavity 11 for clamping and fixing the throttle valve. The material of the elastic component 5 includes rubber.

[0037] The refrigerant circulation system further comprises a bearing component 7 for bearing the throttle valve and a clamp 6 for fixing the elastic component 5 on the bearing component 7. Optionally, the clamp 6 is connected to the bearing component 5 by bolts or screws.

[0038] The mounting cavity 11 of the elastic component 5 is adapted to the refrigerant tube 3, and the refrigerant tube 3 of the throttle valve is mounted and fixed in the mounting cavity 11. The elastic component 5 fixes the throttle valve by clamping the refrigerant tube 3. The mounting cavity 11 extends along the refrigerant tube 3 for a predetermined distance, thereby reducing the vibration of the throttle valve and protecting the refrigerant tube 3 to a certain extent.

[0039] The refrigerant pipe 3 includes a first refrigerant pipe communicating with an inlet of the valve body 2 and a second refrigerant pipe communicating with an outlet of the valve body 2 .

[0040] See also Figure 3 and Figure 4 The installation cavity 11 includes a first installation cavity for fixing the first refrigerant tube and a second installation cavity for fixing the second refrigerant tube, and the first installation cavity and the second installation cavity are arranged side by side.

[0041] like Figure 3 and 4As shown, the elastic component 5 is also provided with an introduction channel 12 for communicating with the installation cavity 11, and the introduction channel 12 extends from the installation cavity 11 to the outer edge of the elastic component 5. The distance between the two introduction channels 12 respectively communicating with the two installation cavities 11 gradually decreases in the direction away from the outer edge of the elastic component 5. The two refrigerant pipes 3 of the throttle valve to be installed and fixed are easy to be close together, so that the distance between the two refrigerant pipes 3 is smaller than the installation distance, and the two introduction channels 12 are arranged obliquely, which is conducive to the refrigerant pipe 3 entering the installation cavity 11 along the introduction channel 12.

[0042] The refrigerant pipe 3 includes a first pipe section 3a connected to the valve body 2 and a second pipe section 3b connected to the first pipe section 3a, wherein the first pipe section 3a and the second pipe section 3b are arranged at an angle. Optionally, the first pipe section 3a and the second pipe section 3b are perpendicular.

[0043] Combination Figure 1 , 2 As shown in , 5 and 6, the above-mentioned bearing member 7 includes a first bearing member 7a and a second bearing member 7b vertically arranged on the bearing surface of the first bearing member 7a. The elastic member 5 is connected to the mounting surface of the second bearing member 7b, and the mounting surface of the second bearing member 7b is perpendicular to the bearing surface of the first bearing member 7a.

[0044] The mounting surface of the second bearing member 7b is provided with a first mounting hole 15 for connecting the clamp 6, and a screw or bolt for connecting the clamp 6 and the second bearing member 7b is passed through the first mounting hole 15. A plurality of mounting holes are arranged side by side along the extension direction of the refrigerant pipe 3 to facilitate adjustment of the relative position of the elastic member 5 and the bearing member 7.

[0045] The elastic component 5 is provided with a protrusion, and the protrusion is provided with a through hole 13 corresponding to the first mounting hole 15 . The screws or bolts used to connect the clamp 6 and the second bearing component 7 b pass through the through hole 13 on the protrusion and the first mounting hole 15 .

[0046] Preferably, the plurality of mounting holes are arranged in a direction inclined relative to the refrigerant tube 3 , so as to adjust the position of the elastic component 5 along the extending direction of the refrigerant tube 3 and in a direction perpendicular to the refrigerant tube 3 .

[0047] The first pipe section 3 a of the refrigerant pipe 3 extends along the mounting surface of the second bearing component 7 b , and the second pipe section 3 b of the refrigerant pipe 3 extends along the bearing surface of the first bearing component 7 a .

[0048] The refrigerant circulation system further includes a connecting component 4 for connecting the refrigerant pipe 3 and the bearing component 9. The connecting component 4 and the elastic component 5 are arranged at intervals in the extending direction of the refrigerant pipe 3. The connecting component 4 rigidly connects the refrigerant pipe 3 and the bearing component 7 together.

[0049] Combination Figure 1 and2 As shown, the second pipe section 3 b of the refrigerant pipe 3 is fixed to the supporting surface of the first supporting component 7 a via the connecting component 4 .

[0050] The elastic component 5 is closer to the valve body 2 than the connecting component 4 in the extending direction of the refrigerant pipe 3. The elastic component 5 is arranged at one end of the refrigerant pipe 3 close to the valve body 2, which is conducive to more effectively reducing the vibration of the throttle valve.

[0051] See also Figure 5 and 6 As shown, the bearing surface of the first bearing member 7a is provided with a second mounting hole 16 for mounting the connecting member 4. A plurality of second mounting holes 16 are arranged side by side along the extending direction of the second pipe section 3b of the refrigerant pipe 3.

[0052] See also Figure 5 and Figure 6 As shown, the bearing member 7 is composed of a plate-like member provided with a flange structure. The flange structure can improve the structural strength of the bearing member 7. Specifically, the flange structure is perpendicular to the plate-like member. Specifically, the first bearing member 7a is provided with a first flange structure 17b, and the second bearing member 7b is provided with a second flange structure 17a.

[0053] The first bearing component 7a and the second bearing component 7b are welded together through the positioning hole 8 to form a stable and reliable bearing component 7. The bearing component 7 can be fixed on the chassis of the unit through two bolt fixing holes 9. The motor 1, the valve body 2 and the two refrigerant pipes 3 form a throttle valve assembly.

[0054] The throttle valve is placed on the bearing component 7, and two connecting components 4 fix the two condensing tubes 3 of the throttle valve on the second bearing component 7b. Optionally, the connecting component 4 is a fixing clamp. The throttle valve is covered with an elastic component 5 made of rubber material, and then the elastic component 5 and the throttle valve are fixed together on the first bearing component 7a with a clamp.

[0055] The refrigerant pipe 3 of the throttle valve is rigidly fixed on the second bearing component 7b by a fixing clamp to prevent the two ends of the throttle valve from being pulled and breaking the pipe.

[0056] The throttle valve is softly fixed on the first bearing component 7a by putting on the elastic component 5 made of rubber material and the clamp 6 to prevent the throttle valve from shaking. The elastic component 5 made of rubber material can absorb the energy generated by the shaking of the throttle valve and eliminate the processing error.

[0057] The introduction channel 12 on the elastic component 5 is designed with a slope, so that the elastic component 5 can be conveniently inserted into the throttle valve, thereby preventing the elastic component 5 from being unable to be inserted due to a large welding error of the refrigerant pipe 3 of the throttle valve.

[0058] The first bearing member 7a and the second bearing member 7b are both designed with an L-shaped cross section in the vertical direction, which can increase the inertia moment in the vertical direction, so that the bearing member 7 can withstand greater force, and the structure is stable and reliable. The first bearing member 7a and the second bearing member 7b are each provided with two positioning holes 8, and the first bearing member 7a and the second bearing member 7b are welded together through the positioning holes 8 to form a bearing member 7 with a stable and reliable structure. Two bolt fixing holes 9 are provided on the second bearing member 7b, and the bearing member 7 can be fixed to the chassis of the unit through the two bolt fixing holes 9.

[0059] Of course, the first bearing component 7a and the second bearing component 7b may also be integrally formed.

[0060] Optionally, the elastic component 5 is provided with a protrusion for clamping the clamp 6. Both ends of the elastic component 5 are provided with a protrusion, and the clamp 6 is located between the two protrusions to prevent the clamp 6 from being separated from the elastic component 5.

[0061] This embodiment provides a fixing structure for synchronously fixing the refrigerant pipe 3 of the electronic expansion valve and the valve body 2 of the electronic expansion valve, which can synchronously fix the refrigerant pipe 3 of the electronic expansion valve and the valve body 2 of the electronic expansion valve, reduce the vibration of the electronic expansion valve, and improve the reliability of the electronic expansion valve. The air conditioning system using this fixing structure is durable. The method and device are simple and reliable, highly practical, and have high promotion value.
