Embodiment Construction

[0019] Such as figure 1 and figure 2 As shown, a pump 10 for a spa or bath has an outer cylindrical housing that is split into four main parts, namely an electric motor housing, fan housing 12 mounted at one end and water pump at the other end. Chamber shell 13. The capacitor case 14 is installed above the motor, and accommodates electrical components and circuits for driving the motor. The fan housing 12 houses a fan 15 driven by an output shaft 16 extending rearwardly and connected to a rotor 17 of the motor 20 . The rotor 17 also includes a forwardly projecting output shaft 25 and the two shafts 16,25 are mounted for rotation about bearing assemblies 26,27. Bearing assemblies 26, 27 are mounted in end plates 28, 29, respectively. The water chamber housing 13 includes a body 30 having a front face 31 and an end face 32 in sealing engagement with the motor end plate 29 . Such as image 3 As shown, the motor 20 is fitted with a rotor 17 for rotation about a laminated st...

Abstract

A kind of pump (10) for spa baths and pools, including a electromotion motor (20) with a output axis (28), this output axis extrudes and passes through the terminal plate component (28) of the water chamber (13) and connects to the impeller inner the chamber (13), the terminal plate component (28) includes a radiator (104) which combines with the power supply heating element (105), one side of the radiator (104) contacts the water inner the chamber (13) while the other side of the radiator (104) has heating element and do not contact the water.

Description

technical field [0001] This invention relates to pumps for spa baths and baths, and more particularly to pumps that include means for heating water flowing through the pump. Background technique [0002] Traditional spa baths and spas use an electrically driven pump to push a mixture of water and air under pressure through adjustable nozzles into the tub or bath. A disadvantage of this arrangement is that it is prone to substantial heat loss, which means that it is difficult to maintain the water temperature at the desired level. [0003] Pumps for spas and baths usually incorporate an electric motor that drives an impeller located in the water chamber. The water chamber is usually supplied with water through the inlet and the pressurized water leaves the pump through the outlet. [0004] It is these problems that lead to the present invention. Contents of the invention [0005] According to one aspect of the present invention, there is provided a pump for a spa bath or...
