Description

  The present invention relates to a bathroom television apparatus fixed to a wall surface of a bathroom.

  In order to appreciate a television screen in the bathroom, many bathroom television devices fixed to the wall surface of the bathroom have been proposed. Since these bathroom television apparatuses are used in a special environment in the bathroom, they are provided with a watertight casing so that moisture does not enter the interior. On the other hand, these bathroom television devices have a built-in liquid crystal display for displaying images, but the amount of heat generated in the casing increases rapidly as the screen becomes larger due to the demand for a large screen.

  Since the seeding is watertight as described above, it is difficult to obtain a sufficient cooling effect even if an air cooling type cooling means is incorporated.

It is known that the liquid crystal display unit is sealed with cooling water, and the heat is transferred from the liquid crystal display unit to another place using the cooling water as a refrigerant so that heat is dissipated therein (see, for example, Patent Document 1). .
Japanese Patent Laying-Open No. 2005-70439 (FIG. 6)

  Although the above-mentioned conventional system uses a liquid refrigerant, the amount of heat taken by the refrigerant from the liquid crystal display unit must be dissipated into the air, and is used for cooling the casing of a bathroom television set fixed in the bathroom. Can not do it.

  Although it is conceivable to draw the refrigerant out of the casing and dissipate the heat, it is necessary to provide a mechanism for returning the dissipated refrigerant to the inside of the casing again and circulating the refrigerant, and the mechanism for cooling becomes large. As a result, there is a problem that the installation location must be secured as well as incurring high costs.

  Then, this invention makes it a subject to provide the bathroom television apparatus which can cool the inside of the casing of a bathroom television apparatus, without using a large-scale mechanism in view of said problem.

  In order to solve the above problems, a bathroom TV apparatus according to the present invention is a bathroom TV apparatus fixed in a bathroom, and includes a liquid crystal display unit for displaying a TV image in a watertight sealed casing. And a water cooling pack for cooling the inside of the casing by receiving the supply of tap water from the outside of the casing.

  There are always plumbing pipes in the bathroom. By guiding tap water from the water pipe to the water cooling pack in the casing, the inside of the casing can be cooled without providing a mechanism such as a circulation pump.

  In addition, when draining the water in the water-cooled pack, it may be drained outside the bathroom, but since the interior of the bathroom can be drained, it is drained into the bathroom without providing a drain path outside the bathroom. No problem at all.

  In addition, it is not always necessary to flow tap water through the water-cooled pack, and for example, it may be intermittently flowed according to the temperature condition in the casing. Therefore, it is desirable to provide an electromagnetic on-off valve that opens and closes in response to a signal from the bathroom television set on the upstream side of the water-cooled pack.

  As is clear from the above description, the present invention cools the inside of the casing of the bathroom television apparatus with tap water, so that it is not necessary to provide a circulation pump or a heat radiating section, and the bathroom television apparatus is installed in the bathroom. Since it is installed, tap water can be used easily.

  Referring to FIG. 1, reference numeral 1 denotes a bathroom television apparatus according to the present invention, which is fixed to a bathroom wall BR. Since it is used by being fixed to the bathroom wall BR, the casing of the bathroom TV apparatus 1 adopts a watertight structure.

  Referring to FIG. 2, the casing of bathroom television apparatus 1 includes a base portion 21 fixed to wall surface BR and a front portion 22 joined to base portion 21. The base portion 21 and the front portion 22 are both made of resin. A heat generating wire is sandwiched between the joint surfaces of the both, and the heat generating wire is energized to melt both the joint surfaces of the base portion 21 and the front portion 22 and press them against each other for watertightness. The sex is secured. Reference numeral 24 denotes a removable decorative cover.

  Before the base portion 21 and the front portion 22 were welded together, the substrate provided with the liquid crystal display portion 23 and the water cooling pack 3 were set so as to be built in the casing. The water-cooled pack 3 is obtained by heat-welding two soft resin sheets to each other so that a water passage is formed therein. An inflow pipe 31 is connected to one end of the water passage, and an outflow pipe 32 is connected to the other end. Connected. The inflow pipe 31 and the outflow pipe 32 were led out from a communication hole provided in the base portion 21.

  Referring to FIG. 3, reference numeral 4 denotes a water pipe, which is connected to a currant 41 provided in the bathroom and supplies tap water to the currant 41. An inflow pipe 31 was connected to the water pipe 4. In addition, the outflow pipe 32 was extended to a place where water can be appropriately drained outside the bathroom.

  An electromagnetic opening / closing valve 5 is provided in the middle of the inflow pipe 31. The open / close valve 5 is closed when not energized, and if the valve is closed, the tap water in the water pipe 4 does not flow into the water cooling pack through the inflow pipe 31.

  The on-off valve 5 is connected to the control unit 25 in the bathroom television apparatus 1 and is configured to energize the on-off valve 5 from the control unit 25. This control unit 25 is provided with a temperature detection means (not shown), and is configured to open the on-off valve for a predetermined time when the temperature in the casing exceeds a predetermined temperature. It should be noted that the temperature detecting means may not be provided, and the open / close valve 5 may be periodically opened while the liquid crystal television apparatus 1 is energized.

  When the opening / closing valve 5 is opened, the tap water in the water pipe 4 flows into the water passage of the water cooling pack 3 through the inflow pipe 31. And it drains from the outflow pipe 32 to an appropriate place. As the tap water flows through the water-cooled pack 3, the water-cooled reactor of the water-cooled pack 3 is filled with low-temperature tap water, so that the tap water absorbs the heat in the casing and the casing is cooled.

  By the way, although the outflow pipe 32 may be extended outside the bathroom, as shown in FIG. 4, the outflow pipe 32 is connected to the drain pipe 6 through the front portion 22, and is discharged from the water cooling pack 3 through the water distribution pipe 6. You may make it drain the tap water which comes into the bathroom. Moreover, when the flow rate of the tap water flowing through the water passage of the water cooling pack 3 is not so large, the drainage pipe 6 may be used to drain the water to the wall surface BR without using it.

  Although the opening / closing valve 5 is used in FIG. 3, as shown in FIG. 5, the inflow pipe 31 is connected to the upstream side of the water pipe 4, and the outflow pipe 32 is connected to the downstream side of the water pipe 4, for example, near the currant 41. You may connect to. If comprised in this way, the tap water after cooling can be discharged from the currant 41, without draining. Moreover, tap water can be flowed through the water-cooled pack 3 each time the currant 41 is opened without providing the opening / closing valve 5 and the like.

  In addition, this invention is not limited to an above-described form, You may add a various change in the range which does not deviate from the summary of this invention.
