El elemento calefactor 22 se dispone sustancialmente ortogonal al rodete 6 e incluye un orificio 23b central que es atravesado parcialmente por dicho rodete 6. En las realizaciones mostradas en las figuras 1 a 3, el elemento calefactor 22 comprende una resistencia de película gruesa que se deposita sobre el elemento conductor 23 por medio de técnicas conocidas tales como el serigrafiado. En otras realizaciones no representadas, el elemento calefactor 22 puede comprender una resistencia tubular.Moreover, the heating device 8 comprises at least one heating element 22, and one element conductor 23 in thermal contact with the heating element 22. The conductive element 23 is substantially flat, disk-shaped and It is made of a heat conducting material, mainly metallic, the conductive element 23 being fixed to the heating element 22 through known manufacturing methods.

El cuerpo hidráulico 10 comprende una pared exterior 10b cilíndrica y un saliente anular 10c cilíndrico que se extiende axialmente en el interior, concéntrico a la pared exterior 10b, desde un fondo 10a de dicho cuerpo hidráulico 10. A su vez, el dispositivo de calentamiento 8 se inserta de forma estanca en el interior del cuerpo hidráulico 10, entre la pared exterior 10b y el saliente anular 10c, y apoyado sobre el fondo 10a, disponiéndose el elemento calefactor 22 enfrentado a dicho fondo 10a.The hydraulic body 10 comprises a wall cylindrical outer 10b and a cylindrical annular shoulder 10c which is extends axially inside, concentric to the outer wall 10b, from a bottom 10a of said hydraulic body 10.

Por otro lado, el elemento calefactor 22 tiene una superficie máxima que le permite insertarse en el interior del cuerpo hidráulico 10, para calentar rápidamente el agua que entra por el conducto de entrada 11b impulsada hacia la cámara de rodete 13 por el rodete 6. De este modo, el agua alojada en la cámara de rodete 13 absorbe rápidamente el calor transferido por el elemento conductor 23 y sale caliente por el conducto de salida 11c hacia una cámara de lavado correspondiente no representada, evitándose la ebullición de dicho agua y el calentamiento excesivo del elemento calefactor 22.On the other hand, the heating element 22 has a maximum surface that allows it to be inserted inside the hydraulic body 10, to quickly heat the incoming water by the inlet duct 11b driven towards the impeller chamber 13 by the impeller 6. Thus, the water housed in the chamber of impeller 13 quickly absorbs the heat transferred by the element conductor 23 and comes out hot through the outlet duct 11c towards a corresponding washing chamber not shown, avoiding boiling of said water and excessive heating of the element heater 22.
El intercambio de calor llevado a cabo en la cámara de rodete 13 puede ser alterado modificando las características hidráulicas de la bomba de circulación de fluido 1, y/o modificando la superficie de transmisión de calor del dispositivo de calentamiento 8.The heat exchange carried out in the impeller chamber 13 can be altered by modifying the hydraulic characteristics of the fluid circulation pump 1, and / or modifying the heat transmission surface of the heating device 8.

Así, en la segunda realización de la invención mostrada en la figura 2, la cápsula 12 comprende un nervio 40 anular, concéntrico a la cápsula 12, que se extiende axialmente, desde una superficie de fondo 12c de dicha cápsula 12, hacia el interior de la cámara de rodete 13. El nervio 40 anular modifica la geometría de la cámara del rodete 13, y por tanto las características hidráulicas de la bomba de circulación de fluido 1. En otras realizaciones, no mostradas, la cápsula puede incluir otros elementos que modifiquen la geometría de la misma.Thus, in the second embodiment of the invention shown in figure 2, capsule 12 comprises a rib 40 annular, concentric to capsule 12, which extends axially, from a bottom surface 12c of said capsule 12, towards the inside the impeller chamber 13. The annular rib 40 modifies the geometry of the impeller chamber 13, and therefore the hydraulic characteristics of the fluid circulation pump 1. In other embodiments, not shown, the capsule may include other elements that modify its geometry.
Por otra parte, en la figura 3 se muestra una tercera realización de la invención en donde la efectividad del intercambio de calor entre el agua bombeada y el dispositivo de calentamiento 8 es mejorada, modificando las características hidráulicas de la bomba de circulación de fluido 1 y la superficie de transmisión de calor del dispositivo de calentamiento 8. Para ello, la cápsula 12 comprende un elemento conductor auxiliar 31 que se fija en el interior del extremo libre de la segunda parte 12b de dicha cápsula 12, siendo el elemento conductor auxiliar 31 anular, de sección transversal sustancialmente en C y hecho de un material conductor de calor, principalmente metálico. Dicho elemento conductor auxiliar 31 modifica las características hidráulicas de la bomba de circulación de fluido 1 en cuanto que modifica la geometría de la cámara de rodete 13, y por otro lado, contacta con el elemento conductor 23 del dispositivo de calentamiento 8 aumentando la superficie de intercambio de calor.On the other hand, figure 3 shows a third embodiment of the invention wherein the effectiveness of the heat exchange between the pumped water and the device heating 8 is improved, modifying the characteristics Hydraulic fluid circulation pump 1 and surface Heat transfer of heating device 8. For thus, the capsule 12 comprises an auxiliary conductive element 31 that it is fixed inside the free end of the second part 12b of said capsule 12, the auxiliary conductive element 31 being annular, of cross section substantially in C and made of a material Heat conductor, mainly metallic.
