Description

Technical Field

[0001] The invention belongs to the technical field of constant temperature heating for leisure pools, and in particular relates to an unpowered constant temperature water and heating system for leisure pools. Background Art

[0002] As the main leisure pool, hot spring bathing pools are mostly set up outdoors, and the peak season for hot spring bathing is mostly in autumn and winter. Due to the low outdoor temperature, in order to ensure the comfort of guests bathing, these outdoor hot spring bathing pools need to continuously replenish heat and raw water for the bathing pool water to ensure the comfortable water temperature of the bathing pool water. At present, the hot spring bathing pool heating usually adopts a circulating constant temperature method, that is, the water of the outdoor bathing pool is centrally pumped back, and a special heating circulation system is set up. The heat medium water is heated by a large gas boiler or electric boiler, and then the heat medium water and the cooled hot spring water pumped back from the bathing pool are exchanged through a heat exchanger, and finally the heated water is re-injected into the bathing pool. The main disadvantages are large equipment investment and high operating energy consumption.

[0003] In order to reduce operating costs, some small and medium-sized hot springs choose to use solar collectors to collect solar heat, converting the sun's light energy into thermal energy to heat the heat medium water. However, the daylight hours are short in winter and the sunlight is not strong enough to heat a large amount of heat medium water to the required temperature. Gas or electric heating is still needed for supplemental heating. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the existing hot spring pool solar heating cannot heat a large amount of heat medium water to the required temperature and still requires gas or electric heating for heating. Instead, a non-powered constant temperature water heating system for a leisure pool is proposed. The principle of hot water rising and cold water falling is used to siphon only the upper hot water to the next level heating tank through a siphon tube for reheating. The water temperature can be quickly heated to the required temperature, no gas or electric heating is required for heating, the energy consumption is small, and the operating cost is low.

[0009] A heating and water replenishment system, the heating and water replenishment system comprises at least a primary heating tank, a secondary heating tank and a tertiary heating tank, the primary heating tank and the secondary heating tank are both provided with solar collectors, the water inlet at the bottom of the primary heating tank is connected to the disinfection device through a water replenishment inlet pipe, the water outlet of the primary heating tank is provided with a first siphon, the inlet end of the first siphon is connected to a first hose, a traction line is fixed to the first hose near the inlet end, a first float is fixed to the traction line, the inlet of the first hose is located below the first float, the outlet end of the first siphon is inserted into the bottom of the secondary heating tank A first siphon control valve is arranged on the first siphon pipe, a second siphon pipe is arranged in the second-stage heating tank, an inlet end of the second siphon pipe is connected with a second hose, a traction line is fixed near the inlet end of the second hose, a second float is fixed on the traction line, the inlet of the second hose is located below the second float, the outlet end of the second siphon pipe is inserted into the bottom of the tertiary heating tank, a second siphon control valve is arranged on the second siphon pipe, a drain port is arranged on the side wall of the tertiary heating tank, a height of the drain port is higher than a height of the outlet ends of the first siphon pipe and the second siphon pipe, and the drain port is connected to the water inlet main pipe.

[0010] Furthermore, it also includes a central control system, which is electrically or communicatively connected to the bubble pool system, the water return system, the purification system and the heating and water replenishment system respectively.

[0011] Furthermore, the heating and water replenishment system further comprises a raw water replenishment pipeline, one end of which is connected to a raw water source, and the other end is respectively connected to a water inlet and / or a replenishment outlet pipe of the primary heating tank, and the raw water source comprises a tap water source and / or a hot spring raw water source. It is used to directly replenish raw water to the pool system, or to replenish the pool system with raw water after being heated by the heating and water replenishment system.

[0012] Furthermore, the return water pipe is also connected to a primary purification device, which is connected to a return water temporary storage tank, for performing preliminary filtering and purification on the return water before it enters the return water temporary storage tank, thereby reducing the cleaning frequency of the return water temporary storage tank.

[0013] Furthermore, the water purifier includes a first water purifier and a second water purifier, the inlet of the first water purifier is connected to the water main pipe through a first water delivery branch pipe, the inlet of the second water purifier is connected to the water main pipe through a second water delivery branch pipe, a first water delivery valve is provided on the first water delivery branch pipe, a second water delivery valve is provided on the second water delivery branch pipe, and the outlets of the first water purifier and the second water purifier are both connected to the disinfection device.

[0015] Furthermore, the bubble pool is also provided with a bubble pool liquid level transmitter and a bubble pool temperature transmitter, which can monitor the liquid level and water temperature in the bubble pool in real time, and compare them with the set temperature and liquid level thresholds to determine whether it is necessary to open the water inlet control valve to replenish water and heat or open the drain control valve to drain water.

[0016] Furthermore, a mixed flow distributor is provided in the bubble pool, and the mixed flow distributor is connected to the water inlet of the bubble pool; the replenishing water entering the water inlet can be quickly dispersed and quickly mixed with the water in the bubble pool, avoiding excessive local temperature caused by sudden water inflow at the water inlet, thereby preventing scalding.

[0020] (2) A solar collector is installed outside the primary heating tank to transfer the heat radiated by the sun on the collector to the primary heating tank in time, heating the water in the primary heating tank. The water near the outer wall of the primary heating tank absorbs heat first and heats up, its specific gravity decreases, and it moves upward continuously. The low-temperature water in the middle of the primary heating tank is replenished, forming a water circulation system in which hot water rises and cold water is replenished. The hot water rises continuously and is stored in the upper part of the primary heating tank. At this time, the upper hot water is siphoned into the secondary heating tank by the first siphon. Only this part of the hot water is reheated, which can quickly increase the water temperature and make the water temperature reach the required temperature. Since the first siphon is connected to the first hose, and the end of the first hose is connected to the first float, under the traction of the first float, the inlet of the first hose is always kept a little below the liquid level, avoiding the failure of the first siphon due to air inhalation, and ensuring that the hot water entering the secondary heating tank is always the upper hot water.

[0021] (3) A central control system is set up to perform automatic control through the central control system to achieve precise control of the temperature in the bubble pool.

[0022] (4) The entire process does not require gas or electric heating for supplementary heating, has low energy consumption and low operating costs, and is suitable for all large, medium and small soaking pools. BRIEF DESCRIPTION OF THE DRAWINGS
