Description

  The present invention relates to a humidifying pan suitable for humidifying air below the freezing point supplied to a snow making unit such as a snowfall device, and more specifically, ice generated in the humidifying pan by stopping circulation of water in the humidifying pan. However, the present invention relates to a humidifying pan that can prevent the water from flowing into the drain of the humidified pan due to the start of water recirculation.

  For example, when supplying humidified air below freezing point to a snow making part such as an artificial snowfall device, a humidifying pan filled with low water temperature water set at a water temperature of 40 ° C. or less, for example, is provided in an air passage through which the air below freezing point circulates, There is a case in which an apparatus configured to generate air that is moistened beyond ice saturation by containing moisture evaporated from the water in the humidifying pan may be used (for example, see Patent Document 1).

  And when temporarily stopping snow making in the artificial snowfall device as described above, it takes time until the supply temperature is stabilized once the supply of air below the freezing point to the snow making part is stopped. Although it is continuously supplied, the supply of humidifying water to the humidifying pan is generally stopped to save energy, and if the supply of water to the humidifying pan is stopped, the water can be frozen in the humidifying pan. Drain the humidified pan to prevent this.

  However, even if the supply of water to the humidifying pan is stopped and the water is drained from the humidifying pan, some water remains in the humidifying pan and air below freezing point continues to flow through the air passage. Therefore, the water remaining in the humidifying pan freezes to become ice.

  Then, when the suspension of snow making in the snowfall device or the like is canceled and the supply of water to the humidifying pan is resumed, a part of the heat from the newly supplied ice is applied to the bottom of the humidifying pan. Melting and unmelted ice floats on the surface of the water and is led to the drainage port. The drainage port is blocked and the drainage itself cannot be performed, or ice is clogged in the drainage port and the amount of drainage is reduced. Water that could not be overflowed from the humidifying pan and dropped into the air passage, causing water leakage.

Japanese Patent No. 3397582 (pages 1-5, FIGS. 1-5)

  According to the present invention, it is possible to provide a humidified pan that can prevent the ice generated in the humidified pan from blocking the drain outlet, and thus does not cause water leakage from the humidified pan.

  In order to solve the above-described problem, a humidifying pan according to the present invention is a humidifying pan provided in an air passage through which air below freezing circulates, and is provided around a drain outlet for draining water in the humidifying pan. An ice inflow prevention member that prevents passage of ice to the drain outlet so as not to flow into the drain outlet is provided.

  Further, the ice inflow prevention member is composed of a plurality of rod-shaped members, and the rod-shaped members are erected from the inner bottom portion of the humidifying pan body in the humidifying pan so that each rod-shaped member surrounds the periphery of the drain outlet. is there.

  Further, the gaps of the rod-shaped members are set to be intervals smaller than the inner diameter of the drainage port, and the tip height of the rod-shaped member is set higher than the upper end edge of the drainage port in the humidifying pan.

  According to the humidifying pan of the present invention, since the rod-shaped ice inflow preventing member is disposed so as to surround the peripheral edge of the water outlet in the humidifying pan, the supply of water to the humidifying pan is temporarily stopped and thereafter In addition, when water is supplied into the humidifying pan, even if the ice in the humidifying pan is led to the drain outlet in the humidifying pan together with the drained water, only ice with a large size is placed in front of the drain outlet by the ice inflow prevention member. Since the water and fine ice fragments are drained from the drain outlet, the drain outlet is hardly clogged with ice, and water leakage from the humidifying pan can be prevented.

In addition, the ice stopped by the ice inflow prevention member is melted by the heat of the humidifying water with the passage of time and the size gradually decreases, and when it becomes smaller than the inner diameter of the drain outlet, it slips between the ice inflow prevention members. Therefore, the water surface is not covered for a long time by the ice stopped by the ice inflow prevention member, and therefore the water circulation into the humidifying pan is resumed for a short time. The amount of moisture evaporation (humidification) from water can be stabilized over time.
From the above, even when the humidification chamber is kept at a low temperature, water can be freely supplied to and stopped from the humidification pan.

Embodiments of a humidifying pan according to the present invention will be described below based on specific examples shown in the accompanying drawings.
The humidifying pan 1 includes an ice inflow prevention rod 6 (for example, a cross section having a diameter of about 2 mm) so as to surround the periphery of the drainage port 4 for draining the water 8 supplied from the water supply port 3 by the water supply pipe 3a. A circular rod) is erected from the inner bottom 2a of the humidifying pan body 2.
In addition, it is preferable to form the humidification bread | pan main body 2 using the material excellent in rust prevention, such as a stainless steel material.

  As shown in FIG. 4, the humidifying pan 1 is arranged in multiple stages in a humidifying chamber 10 that is an air passage for humidifying air below a freezing point supplied to a snow making chamber such as a snowfall device.

  And since ice floats on the water surface and moves, it is normal that the ice inflow prevention member (ice inflow prevention rod 6) does not have to be disposed in the lower peripheral portion of the drain port 4. By setting up the ice inflow prevention rod 6 which is an inflow prevention member from the inner bottom 2a of the humidifying pan body 2, the ice 9 which is peeled off from the bottom 2a of the humidifying bread main body 2 and is floating on the water surface 8a of the water 8 is removed. The structure is designed so that the ice inflow prevention member (ice inflow prevention rod 6) is not provided and does not pass through the lower part of the peripheral edge of the drain port 4 and flow into the drain port 4.

The interval between the inflow prevention rods 6 is set to be slightly smaller than the inner diameter of the drain port 4, and as shown in FIG. When the ice 9 melts to such a size that it can flow into the drainage port 4, the ice 9 passes between the ice inflow prevention rods 6 and flows out of the drainage port 4 together with the water 8.
That is, the ice 9 stopped by the ice inflow prevention rod 6 is prevented from covering the water surface 8a for a long time.

  Further, as shown in FIG. 2, the tip of the ice inflow prevention rod 6 slightly protrudes on the water surface 8 a when the humidification pan body 2 in the humidification pan 1 is full, that is, the height of the ice inflow prevention rod 6. Is set to be slightly larger than the height of the upper end of the drain port 4 so that the ice 9 that is about to flow into the drain port 4 can be stopped more reliably, and the ice that appears on the water surface 8a. The temperature of the water 8 is transmitted to the tip portion of the inflow preventing rod 6 so that the tip portion of the ice inflow preventing rod 6 is not frosted.

  In addition, the code | symbol 5 in a figure is the heat insulating material which consists of raw materials, such as urethane and polystyrene which are covered on the outer surface of the humidification bread | pan main body 2 in the humidification bread | pan 1. As shown in FIG.

  Reference numeral 7 in the figure is a water passage hole 7 disposed near the bottom of the humidifying pan body 2 in the portion of the drainage pipe 4 a connected to the drainage port 4 that passes through the humidifying pan body 2. When the supply of the water 8 is temporarily stopped, the water 8 remaining in the humidifying pan body 2 in the humidifying pan 1 flows into the drain pipe 4a and is drained from the water passage hole 7.

  In the embodiment described above, the details of the supply of the humidifying water to the humidifying pan 1 are not described, but normally the water discharged from the drain 4 is heated to a predetermined temperature (for example, 40 ° C.) again. It is a circulation type that is supplied to the humidifying pan.
