EFFICIENT SHOWER TRAY WITH A STATIC HEAT RECOVERY DEVICE INTEGRATED IN ITS SURFACE, ACCESSIBLE AND EASY TO CLEAN

Abstract

Efficient shower tray with a static heat recovery device integrated in its surface, accessible and easy to clean that channels used water, causing it to run over the outer surface of a flat heat exchanger integrated in the surface of the tray, while cold water which is pre-heated before being mixed circulates inside the heat exchanger, reducing the quantity of hot water required and hence the energy required for heating water. The outer surface over which used grey water runs is accessible and easy to clean, thus ensuring simple and continuous maintenance, and the flat design of the heat exchanger allows the heat exchanger to be mounted flush with a surface, with a reduced height, and to be used without restrictions by persons having reduced mobility.

The assembly can accommodate a grey water lifting pump in order to conduct the water for re-use or discharge.

Claims

1. Flat and efficient shower tray, with a flat sandwich panel-type heat recovery device integrated in its surface, placed in a side channel, accessible for cleaning, having: A shower platform (20) that receives the water from the shower and directs it by slopes towards the side water-flow channel (30). The side water-flow channel (30) is located on any side of the shower platform (20). Located in the side water-flow channel there is a heat exchanger, flat sandwich panel-type heat exchanger (40) that only comes into contact with the grey water on the upper side of the heat exchanger, which has a cold water inlet (50) and a preheated water outlet (60). The grey water used in the shower runs along the water-flow side channel (30), in contact with the upper part of the flat sandwich panel-type heat exchanger (40), toward the grey water evacuation and collection point (70). The grey water from the shower, leaves along its route part of the energy in the network water, which enters through the cold water inlet (50) and exits for use through the preheated water outlet (60).

2. Flat and efficient shower tray, with a flat sandwich panel-type heat recovery device integrated in its surface, placed in a side channel, accessible for cleaning, according to claim 1, characterised in that the channel is further covered with a front lid (80) and another side lid (90) which are removable for access and cleaning of the flat sandwich panel-type heat exchanger (40). The function of the lids (80) and (90) is aesthetic and to provide the shower tray assembly with a flat surface.

3. Flat and efficient shower tray, with a flat sandwich panel-type heat recovery device integrated in its surface, placed in a side channel, accessible for cleaning, according to claim 1, characterised in that it further comprises a grey water evacuation and collection point (70) which houses a grey water lifting pump (71), to direct it to the drain and/or a grey water collection tank (100).

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Below is a very brief description of a series of drawings for a better understanding of the invention. They are expressly related to an embodiment of said invention, which is presented as an example without limiting the scope thereof.

[0031] FIG. 1 is a perspective sketch of a possible form of manufacture of the assembly of the invention with the grey water collection tank and the grey water lifting pump.

[0032] FIG. 2 shows an exploded perspective view thereof.

DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION

[0033] The energy-efficient shower tray proposed by the invention is based on a manufacturing form valid for multiple types of installations in which there is hot water consumption in the shower. For example, the mounted efficient shower tray assembly (10) is shown, provided with a shower platform (20) that receives the water from the shower and directs it toward a side water-flow channel (30) in which the flat sandwich panel-type heat exchanger (40) is located that is provided with a cold water inlet (50) and a preheated water outlet (60), the grey water used in the shower being directed towards the grey water evacuation and collection point (70) leaving part of its energy in the water simultaneously entering the network. The side water-flow channel (30) in which is located the flat sandwich panel-type heat exchanger (40) is located can be covered by a front channel lid (80) and another side channel lid (90) which can be easily removed for cleaning of the flat sandwich panel-type heat exchanger (40). The function of the lids (80) and (90) is largely aesthetic and to do make the base is almost under use conditions.

[0034] Thus a single equipment, as shown in FIGS. 1 and 2, comprises the elements necessary to achieve the desired functions, with a cold water inlet (50), a preheated water outlet (60), a grey water evacuation and collection point (70). This location (70) can incorporate a gap with a grey water lifting pump (71), which recovers the water before being definitively lost down the drain in order to reuse it.

[0035] As shown in the drawing this unit consists of four basic elements that together perform the required functions, a shower platform (20), a flat sandwich panel-type heat exchanger (40) and removable lids (80) and (90) covering the channel and a grey water lifting pump (71), which recovers the water before it being ultimately lost down the drain situated at the grey water evacuation and collection point (70).

[0036] Listed below are the components of the invention with their numerical reference:

10.Mounted efficient shower tray assembly.
20.Shower platform.
30.Side water-flow channel.
40.Flat sandwich panel-type heat exchanger.
50.Cold water inlet.
60.Preheated water outlet.
70.Grey water evacuation and collection point.
71.Grey water lifting pump.
80.Front channel lid.
90.Side channel lid.
100.Grey water collection tank.

[0037] Thus, the invention relates to a mounted efficient shower tray assembly (10), which recovers the heat from the grey water before being evacuated to the outside of the building, and which has:

A platform having: [0038] Slopes that direct the grey water into a side water-flow channel (30) which serves as the route, facilitates the contact between the flat sandwich panel-type heat exchanger (40) with network water inside and the grey water running towards an evacuation point (70), with the possibility of a subsequent use.
A flat heat exchanger having: [0039] A cold water inlet (50), a preheated water outlet (60) and an exchange surface that collects the heat from the grey water to preheat the shower water.
Side and front channel lids: [0040] They are used to provide a flat surface on the mounted efficient shower tray assembly (10) and which can be removed to clean the surface of the heat exchanger.
