Description

[0001] The utility model relates to the technical field of drying equipment, in particular to a compressor and drying equipment. Background Art

[0002] With the global restrictions on carbon emissions and the upgrading of energy efficiency standards for home appliances, traditional electric heating dryers tend to be eliminated due to their energy consumption problems. New heat pump dryers are gradually replacing traditional electric heating dryers. Heat pump dryers use refrigerant vapor compression heating cycle to dry clothes. Their heating energy efficiency ratio is generally 3 to 4, and the heating temperature generally does not exceed 80°C. They are more energy-saving, environmentally friendly, efficient and gentle. However, for compressors used in low-temperature refrigeration fields such as refrigerators, freezers, and freezers, their evaporation temperature is generally between -35℃ and 10℃, and the condensation temperature does not exceed 65℃. The heat pump dryer requires a condensation temperature of about 70℃ for drying clothes, and an evaporation temperature of about 25℃. Therefore, the corresponding suction / exhaust pressure of the compressor used in the heat pump dryer is significantly higher than in the past, and the refrigerant flow rate circulating in the compressor and heat pump system has also increased by 3 to 5 times, which has brought about a significant increase in the flow resistance and pressure fluctuation of the exhaust components inside the compressor, resulting in a decrease in the heating capacity and energy efficiency ratio, resulting in poor working performance, low reliability and high energy consumption of the heat pump dryer.

[0042] Reference below Figure 1-Figure 4 The compressor 100 and the drying device according to the embodiment of the present invention are described.

[0043] like Figure 1 As shown, according to the compressor 100 of the first embodiment of the utility model, the compressor 100 includes: a shell 1, a valve plate 5, a cylinder head 6, an intake assembly and an exhaust assembly.

[0044] Among them, a cylinder chamber 2 and a high-pressure chamber 3 are defined in the shell 1, and a compression pump body 4 is arranged in the cylinder chamber 2; the valve plate 5 has an air intake port and an exhaust port 5b, and is connected with the cylinder chamber 2 through the air intake port and the exhaust port 5b; the cylinder head 6 is covered on the cylinder chamber 2, and the valve plate 5 is located between the cylinder head 6 and the cylinder chamber 2, and the cylinder head 6 has a cylinder head inner cavity, and the cylinder head inner cavity is suitable for communicating with the cylinder chamber 2 through the exhaust port 5b, and the cylinder head inner cavity is connected with the high-pressure chamber 3; the air intake component is connected with the air intake port, and the exhaust component is connected with the high-pressure chamber 3; the volume V1 of the high-pressure chamber 3 is greater than the volume V2 of the cylinder head inner cavity, and the volume V2 of the cylinder head inner cavity is greater than the displacement V3 of the compression pump body 4, and (V2+V1) / V3 is greater than or equal to 4.

[0045] Specifically, the compressor 100 has a shell 1, and the shell 1 defines a cylinder cavity 2 and a high-pressure cavity 3 inside. The cylinder head 6 is covered on the cylinder cavity 2, and the cylinder head 6 has a cylinder head inner cavity. A valve plate 5 is arranged between the cylinder head 6 and the cylinder cavity 2. The cylinder head inner cavity is connected to the cylinder cavity 2 through the exhaust port 5b of the valve plate 5, and the valve plate 5 is connected to the cylinder cavity 2 through the intake port and the exhaust port 5b, and the intake assembly is connected to the intake port of the valve plate 5. The intake assembly can introduce external gas into the cylinder cavity 2, so that the gas can be compressed and pressurized by the compression pump body 4 in the cylinder cavity 2. The gas compressed by the compression pump body 4 can flow from the cylinder cavity 2 to the cylinder head inner cavity through the exhaust port 5b, and the cylinder head inner cavity is also connected to the high-pressure cavity 3, and the high-pressure cavity 3 is connected to the exhaust assembly. Therefore, after the gas flows through the cylinder head inner cavity, it can flow into the high-pressure cavity 3 in the next step. After being stored in the high-pressure cavity 3 for a short time, it can be discharged from the compressor 100 through the exhaust assembly to provide high-temperature and high-pressure working gas for other structures (such as a condenser).

[0046] It should be pointed out that the volume V1 of the high-pressure chamber 3 in the utility model is larger than the volume V2 of the cylinder head inner cavity, and the volume V2 of the cylinder head inner cavity is larger than the displacement V3 of the compression pump body 4. It can be understood that the gas is first compressed at the compression pump body 4, and then flows through the cylinder head inner cavity and the high-pressure chamber 3 in sequence. Therefore, the design that the volume V1 of the high-pressure chamber 3 is larger than the volume V2 of the cylinder head inner cavity, and the volume V2 of the cylinder head inner cavity is larger than the displacement V3 of the compression pump body 4 can provide a buffer space that increases successively for high-flow gas, reduce pressure fluctuations, and reduce exhaust pressure pulsation and flow resistance pressure drop, which can optimize the flow and compression efficiency of gas. At the same time, the size relationship between the volume of the high-pressure chamber 3, the volume of the cylinder head inner cavity and the displacement of the compression pump body 4 in the utility model is also limited to (V2+V1) / V3 greater than or equal to 4, which can ensure that the high-pressure chamber 3 and the cylinder head inner cavity structure size will not be too large on the basis of ensuring that the gas has a good buffer pressure.

[0047] According to the compressor 100 of the present invention, external gas can be introduced into the cylinder chamber 2 by the exhaust component, and the gas is compressed at the compression pump body 4 in the cylinder chamber 2. After compression, it flows through the cylinder head inner chamber and the high-pressure chamber 3 in sequence. By limiting the displacement V3 of the compression pump body 4, the volume V2 of the cylinder head inner chamber and the volume V1 of the high-pressure chamber 3 to V3<V2<V1 and (V2+V1) / V3≥4, sufficient buffer space can be provided for high-flow gas. When the compressor 100 of the present invention is exhausted at a high flow rate, the gas can be smoothly discharged from the cylinder chamber 2 into the high-pressure chamber 3, effectively reducing the exhaust pressure pulsation and the flow resistance pressure drop, thereby improving the overall efficiency and stability of the compressor 100 and helping to improve airflow noise and vibration.

[0048] like Figure 1 As shown, according to some embodiments of the present invention, the volume V1 of the high pressure chamber 3 satisfies: 10 cm 3 ≤V1≤35cm 3 The volume V2 of the inner cavity of the cylinder head satisfies: 6cm 3 ≤V2≤15cm 3 The displacement V3 of the compression pump body 4 satisfies: 3cm 3 ≤V3≤12cm 3 .

[0049] Specifically, the volume V1 of the high pressure chamber 3 in the present invention can be set at 10 cm 3 ~35cm 3 range, for example, V1 can be constructed to be 20cm 3 、25cm 3 or 30cm 3 By setting V1 in the above range, sufficient storage space can be provided for the compressed gas, reducing pressure fluctuations and improving exhaust stability; the volume V2 of the cylinder head cavity in the utility model can be set at 6cm 3 ~15cm 3 Range, for example, V2 can be constructed to be 8cm 3 , 10cm 3 or 12cm 3 By setting V2 in the above range, it is helpful to balance the pressure in the inner cavity of the cylinder head and reduce the mechanical load caused by the sudden change of pressure; the displacement V3 of the compression pump body 4 in the utility model can be set at 3cm 3 ~12cm 3 range, for example, V3 can be constructed to be 5cm 3 、7cm 3 or 9cm 3By setting V3 within the above range, the displacement of the compression pump body 4 matches the compression capacity of the compressor 100, which can well meet the gas compression requirements. By setting the displacement V3 of the compression pump body 4, the volume V2 of the cylinder head inner cavity, and the volume V1 of the high-pressure chamber 3 in specific ranges, the volume of each chamber can be accurately controlled, the performance of the compressor 100 can be optimized, and the best compression and exhaust effects can be achieved under different working conditions.

[0050] It should be noted that the specific values ​​of the displacement V3 of the compression pump body 4, the volume V2 of the cylinder head inner cavity and the volume V1 of the high-pressure chamber 3 are also determined under the conditions of V3<V2<V1 and (V2+V1) / V3≥4. For example, if the displacement V3 of the compression pump body 4 is 7cm 3 , then the volume V2 of the cylinder head cavity should be greater than 7cm 3 , such as V2 can be constructed as 10cm 3 , then the volume V1 of the high pressure chamber 3 should be greater than 10cm 3 At the same time, (V2+V1) / V3≥4, it can be calculated that the volume V1 of the high-pressure chamber 3 should be greater than 21cm 3 , such as V1 can be constructed as 25cm 3 、28cm 3 or 30cm 3 wait.

[0051] like Figure 1 As shown, according to some embodiments of the present invention, the cross-sectional profile of the high-pressure chamber 3 is an oblong shape.

[0052] Specifically, the cross-sectional profile of the high-pressure chamber 3 in the height direction can be constructed as an oblong. On the one hand, the oblong cross-sectional profile is more in line with the principles of fluid dynamics, which helps to optimize the flow path of the airflow, reduce turbulence and pressure loss, and thus improve the efficiency of the compressor 100; on the other hand, the oblong cross-sectional profile can effectively utilize the space inside the shell 1, and within the limited space of the shell 1, the volume of compressed gas stored can be maximized, which is conducive to fully meeting the high-flow gas exhaust requirements; on the third hand, the oblong cross-sectional profile can also reduce the vibration during the gas flow process, which can improve the vibration reduction and noise reduction performance of the compressor 100.

[0053] like Figure 1 and Figure 2 As shown, according to some embodiments of the utility model, a first flow hole 5a is provided on the valve plate 5, and the part of the shell 1 defining the high-pressure chamber 3 has a second flow hole 3a, and the first flow hole 5a is connected with the second flow hole 3a to connect the high-pressure chamber 3 with the inner cavity of the cylinder head.

[0054] Specifically, the first flow hole 5a is formed on the valve plate 5, and the number of the first flow hole 5a can be one or more. The second flow hole 3a is formed in the part of the shell 1 that defines the high-pressure chamber 3, and the number of the second flow hole 3a can also be one or more. The first flow hole 5a is connected to the second flow hole 3a, so that the high-pressure chamber 3 can be connected to the cylinder head inner cavity, thereby forming a cylinder head inner cavity-first flow hole 5a-second flow hole 3a-high-pressure chamber 3 connecting structure. This connecting structure can enable the gas to flow into the high-pressure chamber 3 more smoothly during the exhaust process after compression, and can reduce the residence time of the gas in the cylinder head inner cavity, thereby reducing the exhaust pressure pulsation and flow resistance pressure drop, which can effectively improve the exhaust smoothness and stability, and improve the performance and efficiency of the compressor 100.

[0055] like Figure 3 As shown, according to some embodiments of the present invention, the first through-flow hole 5a and the second through-flow hole 3a are both one, and are configured as any one of an oblong hole and an elliptical hole, and the equivalent diameter is 5 mm.

[0056] Specifically, the first through-flow hole 5a and the second through-flow hole 3a can be configured as an oblong hole or an elliptical hole. By adopting an oblong hole or an elliptical hole as the contour shape of the first through-flow hole 5a and the second through-flow hole 3a and setting its equivalent diameter to 5 mm, the flow path and flow characteristics of the gas can be further optimized, the turbulence and pressure loss of the gas during the flow process can be reduced, the exhaust pressure pulsation and flow resistance pressure drop can be further reduced, and the exhaust performance of the compressor 100 can be improved. In addition, configuring the first through-flow hole 5a and the second through-flow hole 3a as an oblong hole and an elliptical hole can also help reduce vibration during the gas flow process and optimize the vibration reduction and noise reduction performance of the compressor 100.

[0057] like Figure 4 As shown, according to some embodiments of the present invention, the first through-flow hole 5a and the second through-flow hole 3a are both constructed as at least two circular holes, and the equivalent diameter of each circular hole is 3.5 mm.

[0058] Specifically, the first through-flow hole 5a and the second through-flow hole 3a can be constructed as circular holes, and the number of the two is at least two. By constructing the first through-flow hole 5a and the second through-flow hole 3a as circular holes and setting the equivalent diameter of each circular hole to 3.5 mm, a larger gas flow area can be provided, which is conducive to further increasing the flow of gas between the high-pressure chamber 3 and the inner cavity of the cylinder head, and reducing the gas pressure resistance, which can improve the gas flow and exhaust efficiency in the compressor 100. The number of the first through-flow hole 5a and the second through-flow hole 3a is at least two, which can achieve that multiple circular holes can promote the uniformity of gas flow between the high-pressure chamber 3 and the inner cavity of the cylinder head, reduce the local pressure loss and turbulence of the gas, and further improve the energy efficiency of the compressor 100.

[0059] In other embodiments, the first through-flow hole 5a and the second through-flow hole 3a both include a first hole and a second hole, the first hole is configured as an oblong hole or an elliptical hole, and the number is one, and the second hole is configured as a circular hole, and the number is at least two. The structural form of the oblong or elliptical first hole and the circular second hole can effectively improve the gas flow resistance and pressure fluctuation, and fully optimize the exhaust performance and working efficiency of the compressor 100.

[0060] like Figure 1 As shown, according to some embodiments of the present invention, the air intake assembly includes: an air intake pipe 7 and an air intake muffler.

[0061] The air intake pipe 7 is connected to the shell 1 , the air intake muffler is arranged on the air intake pipe 7 , and the inner cavity of the shell 1 is connected to the cylinder cavity 2 .

[0062] Specifically, the air intake pipe 7 has a certain length, at least part of the air intake pipe 7 can be arranged on the outer periphery of the shell 1, and the air intake pipe 7 is connected with the shell 1, the air intake pipe 7 can smoothly introduce the external gas into the shell 1, and the shell 1 inner cavity of the shell 1 is connected with the cylinder cavity 2. It should be pointed out that the air intake port of the valve plate 5 can be connected with the air intake pipe 7 and the inner cavity of the shell 1. After the gas flows through the air intake pipe 7 and the inner cavity of the shell 1, it can flow into the cylinder cavity 2 from the air intake port of the valve plate 5, which is equivalent to the valve plate 5 connecting the air intake pipe 7 with the cylinder cavity 2, so that the gas can enter the cylinder cavity 2 from the outside to be compressed at the compression pump body 4. The air intake muffler of the utility model can be arranged on the air intake pipe 7 and located in the inner cavity of the shell 1. The sound-absorbing muffler can reduce the noise generated during the air intake process to reduce the noise and vibration of the compressor 100 during the air intake process. In this way, the operating reliability and stability of the compressor 100 can be improved, and the working environment can be improved.

[0063] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the exhaust assembly includes: an inner exhaust pipe 81 and an exhaust pipe 82 .

[0064] The inner row pipe 81 is communicated with the high pressure chamber 3 , and the exhaust pipe 82 passes through the shell 1 and is connected with the inner row pipe 81 .

[0065] Specifically, the exhaust pipe 82 has a certain length, at least part of the exhaust pipe 82 can be located on the outer periphery of the shell 1, and at least another part of the exhaust pipe 82 can pass through the shell 1. The exhaust pipe 82 is used to discharge the gas outside the compressor 100. The exhaust pipe 82 is connected to the inner row pipe 81 in the shell 1, and the inner row pipe 81 can be arranged at the exhaust end of the high-pressure chamber 3. The inner row pipe 81 is located in the shell 1 and has a certain length. One end of the inner row pipe 81 in the extension direction is connected to the high-pressure chamber 3, and the other end can be connected to the exhaust pipe 82. It can be understood that the inner row pipe 81 is located between the high-pressure chamber 3 and the exhaust pipe 82, and connects the high-pressure chamber 3 with the exhaust pipe 82. The inner row pipe 81 can have a bending or bending angle to ensure that the high-pressure chamber 3 and the exhaust pipe 82 located at different positions of the shell 1 can be smoothly connected, so that the gas in the high-pressure chamber 3 can be diverted to the exhaust pipe 82, and then the gas is discharged from the exhaust pipe 82 to the compressor 100.

[0066] like Figure 1 As shown, according to some embodiments of the present invention, the compressed working medium in the compressor 100 is configured as propane, and the ratio of the exhaust pressure of the exhaust component to the intake pressure of the intake component is 2-6.

[0067] Specifically, since propane has the characteristics of high energy density, good thermal conductivity, low cost, safety and environmental protection, by configuring the compressed working fluid in the compressor 100 as propane, the compressed working fluid in the compressor 100 can store more energy and transfer heat more effectively, so as to improve the working efficiency and energy efficiency of the compressor 100. At the same time, it is also beneficial to save costs and improve the working safety and environmental protection of the compressor 100.

[0068] It should be pointed out that when the ratio of the exhaust pressure of the exhaust component to the intake pressure of the intake component is too small, such as the ratio of the exhaust pressure to the intake pressure is 0.5 or 1, the gas will not be fully compressed, resulting in low compression efficiency and high energy consumption of the compressor 100, and under low pressure ratio, the compressor 100 needs to run more frequently to maintain the required exhaust pressure, which may easily lead to an increase in the load of the compressor 100, thereby accelerating equipment wear and aging, and shortening the service life; when the ratio of the exhaust pressure of the exhaust component to the intake pressure of the intake component is too large, such as the ratio of the exhaust pressure to the intake pressure is 8 or 9, the exhaust pressure is too high, and in order to maintain a stable compression ratio, the intake pressure needs to be reduced, which may easily lead to insufficient intake or increased intake pressure fluctuations, thereby affecting the operating efficiency and reliability of the compressor 100, and when the ratio of the exhaust pressure to the intake pressure is too large, the exhaust temperature of the compressor 100 will also increase significantly, and the high temperature will have an adverse effect on the lubricating oil inside the compressor 100, reduce its lubrication performance, and cause increased equipment wear.

[0069] The utility model sets the ratio of the intake pressure of the intake component to the exhaust pressure of the exhaust component within the range of 2 to 6, so that the ratio of the intake pressure to the exhaust pressure has a suitable range, so that the compressor 100 can operate under good working conditions, which can further improve the compression efficiency and performance of the compressor 100, and is conducive to extending the service life of the compressor 100 and saving maintenance costs.

[0070] According to the compressor 100 of the present invention, the flow path of the gas is: intake pipe 7 → intake muffler → intake port of valve plate 5 → cylinder chamber 2 → compression pump body 4 → exhaust port 5b of valve plate 5 → cylinder head inner cavity → high pressure chamber 3 → inner exhaust pipe 81 → exhaust pipe 82, so as to smoothly realize the intake, gas compression and exhaust operations of the compressor 100.
