Problems solved by technology

Therefore, the crankshaft of the compressor cannot make the rotary protrusion larger due to the limitation of the diameter of the inner hole of the middle pump body partition, which limits the eccentricity of the crankshaft, thereby limiting the upper limit of the displacement of the compressor

Embodiment Construction

[0020] It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other if there is no conflict. Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments.

[0021] Such as Figure 1 to Figure 4 As shown, an embodiment of the present invention provides a compressor including a crankshaft assembly and a roller 30. The crankshaft assembly described above includes a rotary shaft 10 and an eccentric portion 20. Among them, the rotary shaft 10 is provided with a mounting part. The eccentric part 20 is detachably connected with the mounting part to form a pivoting protrusion of the crankshaft assembly. The roller 30 is sleeved on the outer surface of the eccentric portion 20.

[0022] By providing the eccentric part 20 that can be detachably fitted with the mounting part on the rotary shaft 10, the rotary shaft 10 can be inserted into the eccentric...

Abstract

The invention provides a compressor, an air conditioner and a heat-pump water heater system. The compressor comprises a crank shaft component which comprises a rotation shaft and an eccentric portion. An installation portion is arranged on the rotation shaft, and the eccentric portion is detachably connected with the installation portion to form a rotation protrusion of the crank shaft component. By means of the compressor, the eccentric portion capable of being detachably matched with the installation portion on the rotation shaft is arranged, so that the rotation shaft can penetrate an inner hole of a partition plate of a middle pump of the compressor and is then assembled in the eccentric portion during assembly, the crank shaft eccentricity is prevented from being limited by the inner hole size, the crank shaft eccentricity can be larger, and the compressor displacement upper limit is improved.

Description

Technical field [0001] The present invention relates to the field of temperature regulating devices, and in particular to a compressor, air conditioner and heat pump water heater system. Background technique [0002] The crankshafts of the compressors in the prior art are all integrated designs of a rotary shaft and a plurality of rotary protrusions. Because the compressor needs to make the crankshaft pass through the inner hole of the intermediate pump body diaphragm and extend to the set position during the assembly process. Therefore, the crankshaft of the compressor cannot be made larger due to the diameter of the inner hole of the intermediate pump body diaphragm, which limits the eccentricity of the crankshaft, thereby limiting the upper limit of the compressor displacement. Summary of the invention [0003] The invention aims to provide a compressor, air conditioner and heat pump water heater system to achieve the purpose of increasing the upper limit of the compressor dis...
