DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings showing an embodiment. FIG. 1 is an exploded perspective view of the faucet and the present apparatus. First, the faucet 1 will be described with reference to FIG. The illustrated faucet 11 includes an opening / closing mechanism section 2 having a built-in valve for opening and closing a passage by a valve mechanism, an opening / closing operation section 3 for opening and closing the opening / closing mechanism section 2, and a discharge section 4 for discharging water. Have been. In addition, although the discharge part 4 of the general faucet 1 is formed integrally with the housing of the opening and closing mechanism part 2,
In the discharge section 4 of this example, the nozzle is rotatably connected to the opening and closing mechanism section 3.

Next, a cover as a cover constituting the anti-freezing device will be described. The cover shown in FIG. 1 includes a pair of lids 5, 5 formed separately. The pair of lids 5 and 5 are fitted from both right and left sides of the faucet 1 with the faucet 1 at the center. Each of the pair of lids 5 and 5 is set in advance so that at least two through holes corresponding to the distal end port of the discharge unit 4 and the position of the shaft of the opening and closing operation unit 3 are formed in the combined state. Semicircular cutouts 6, 6, 7 and 7 for forming through holes at predetermined positions of the lids 5 and 5 are formed. In addition, it is natural that a semicircular cutout (not shown) for forming a through-hole through which the base tube 8 is formed is also provided at the lids 5 and 5 corresponding to the base tube 8 of the faucet 1. .

[0008] The pair of lids 5, 5 are provided with a united engagement portion 10 so that a box-shaped cover is formed by uniting the two. As the united engaging portion 10 of the embodiment, a complementary concave and convex portion is formed on an edge portion which is integrally fitted, and is engaged by detaching and attaching the concave and convex portion.

FIG. 2 is a developed view showing an example in which a pair of mating lids 5, 5 are partially connected to bend freely. Such a form can be realized by integrally molding the lids 5, 5 and the connecting portion 11 of the both with a synthetic resin, and forming the connecting portion 11 to be thin so that it can be bent. Separate or contact 1
Regardless of whether they are formed integrally with one another, a pair of mating lids 5,
5 is preferably formed so as to cover the entire faucet as much as possible with the opening / closing mechanism 2 as the center.

Next, the heating device 20 shown in FIGS. 1 and 3 will be described. The heating device 20 is provided on the inner surface of each of the pair of lids 5. The heating device 20 shown in the embodiment includes:
The lids 5 and 5 are formed separately from each other, and are detachably mounted inside the lids 5 and 5. This heating device 20
Is composed of an insulating resin portion 23, a heater wire 25 embedded in the insulating resin portion 23, and a thermostat 26 thereof. The insulating resin portion 23 of the embodiment is a resin in a state where the two plates 21 and 21 are erected on both sides of the faucet 1 at the center thereof and are foldably connected to face each other. It is one that was integrally molded. The heater wire 25 is connected to the two plates 2 of the insulating resin portion 23.
1 and 21 are buried so as to be connected to each other via a connecting portion 24. Then, the thermostat 26 set in the circuit of the heater wire 25 keeps the heater temperature in an appropriate temperature range. The thermostat 26 is optimally capable of setting the temperature. Reference numeral 22 in the drawing denotes a heat generating portion, which is also buried in the insulating resin portion 23 in the embodiment.
