OBJECT OF THE INVENTION
[0001] The invention here presented relates to a bathroom soap heater with numerous applications
in households, industry, hospitals, sports centres etc., from among the bathroom soap
warming methods.
[0002] The invention is characterised by a construction which comprises a copper coil, outer
thermal insulation and the cover or case made from plastic or metal plate, shaped
and lacquered.
BACKGROUND OF THE INVENTION
[0003] Heating soap for greater comfort during showers is a well known technique. In Great
Britain and Germany, for example, soap thermos flasks have existed for decades, both
in luxury hotels and in industry where workers receive large amounts of grease.
[0004] However, these thermos flasks are generally electrically operated, and therefore
consume a large amount of energy. This type of electrical thermos flask, as well as
any other electrical device inside the shower or bath space is forbidden in Spain
by current laws (Low voltage electro-technical regulations).
[0005] The applicant is unaware of the existence of any bathroom soap heaters of the characteristics
which are described herein.
DESCRIPTION OF THE INVENTION
[0006] The invention object of this memory relates to a bathroom soap heater, applicable
in the household as well as in general hospitals and maternity wards, geriatric hospitals
and senior citizen homes, and in hotels, beauty salons, changing rooms in factories,
sports complexes, etc.
[0007] As is well known, soap is a viscous element which is crucial to personal hygiene,
but which is also cold, at least during Winter, at which time its use is uncomfortable
or even unpleasant. The contrast between the high temperature of the water and the
cold one of the soap, in certain circumstances and climates, can even lead to disregard
for personal hygiene.
[0008] The invention suggests using the warm water from the water faucet to heat the soap
with no superfluous energy consumption.
[0009] The soap is heated by direct contact with a hot surface and the ensuing convection
in the fluid or soap.
[0010] The hot surface consists of a copper coil which has hot water flowing inside it;
heat will be transferred by this copper spiral or any other heat exchanger, such as
by interposing one or more metal plates as in electric radiators.
[0011] Whichever the method, in order to ensure correct operation of the heater two factors
must be considered: the transfer surface must be as large as possible and the volume
of soap to be heated must not be too great.
[0012] The greater the amount of soap to be heated the greater its thermal inertia and thus
the greater the heat transfer surface needed. Otherwise, the time required to heat
the soap may be too long and the heater will no longer be useful.
[0013] Thus, for a low-demand household use a single copper coil and a small amount of soap
to be heated will suffice, while for large demand of soap (as in hospitals or beauty
salons) a battery of plates would be more appropriate.
[0014] In either case, this exchanger must be encased within a thermally insulated container
in order to prevent useless heat loss, and suitably coated with a permanent external
finish with hot water inlets and outlets.
DESCRIPTION OF THE DRAWINGS
[0015] As a complement of the description and in order to aid a better comprehension of
the characteristics of the invention, a set of drawings is attached to the present
descriptive memory as an integral part of the same, in which, for purposes of illustration
and in a non-limiting manner, the following is shown:
Figure 1 shows two transverse and longitudinal sectional views of the household heater.
Figure 2 shows the heater installed in the hot water inlet of a sink.
PREFERRED EMBODIMENT OF THE INVENTION
[0016] In view of the above, the present invention relates to a bathroom soap heater in
two different practical examples of the preferred embodiment, one for individual use
and one for collective use.
[0017] The first case is characterised by being provided with a copper coil (1), outer thermal
insulation (2), coating or case (3), made of plastic or lacquered and conformed metal
plate, with a hot water inlet (4) and outlet (5), as well as a condensation outlet
(6).
[0018] The interior of coil (1) has an opening (7) at the top to fit the soap bottle, or
alternatively it can be closed and provided with a conventional dispenser.
[0019] In the second case, copper coil (1) is replaced by plates made of copper, galvanised
plate or aluminium connected to each other, in addition to an inner case, the thermal
insulation and the outer case, in an arrangement which requires a dispenser.
[0020] This description is not extended in the understanding that any expert in the field
would have enough information to understand the scope if the invention and the advantages
derived thereof, as well as to reproduce the same.
[0021] It is understood that as long as the essence of the invention is unaffected, variations
in materials, shape, size or arrangement of the elements are subject to changes within
the same characterisation.
[0022] The terms used in the description and the description itself shall in all cases be
considered as not limiting.
1. Bathroom soap heater, from among heaters intended for these purposes, for individual
or collective use, essentially characterised in that it is provided with a copper
coil (1), outer thermal insulation (2), coating or case (3), made of plastic or lacquered
and conformed metal plate, with a hot water inlet (4) and outlet (5), as well as a
condensation outlet (6), with the interior of coil (1) having an opening (7) at the
top in order to fit a soap bottle, or as an alternative, closed and provided with
a conventional dispenser.
2. Bathroom soap heater, as claimed in above claim, characterised in that copper coil
(1) is replaced by plates made of copper, galvanised plate or aluminium, connected
to each other, and an inner case, thermal insulation and the outer case, as well as
a conventional dispenser.
