The scope of the embodiments of the present application is only limited by the appended claims.

[0033] As Figures 1-8 shown, the present application provides a bubble generating device of a pool machine, which comprises a shell 1, and a control unit, a heat pump unit and a gas pump unit arranged in the shell 1, the control unit comprises a control panel (not shown in the figure) and a water inlet temperature sensor 102, a water inlet temperature sensor 103 and an ambient temperature sensor 101 connected with the control panel; the shell 1 is provided with a bubble outlet 111, a water inlet 112 and a drain outlet 113. Preferably, the bubble outlet 111 is provided with a third electric valve 203, the water inlet 112 is provided with a first electric valve 201, and the drain outlet 113 is provided with a second electric valve 202.

[0034] The water side of the heat pump unit comprises a water side heat exchanger, and a water circulation pipeline through the water side heat exchanger, the water circulation pipeline is provided with a circulating water pump 21, a water inlet temperature sensor 102 and a compressor 12, the inlet of the water circulation pipeline is communicated with the water inlet, and the outlet of the water circulation pipeline is communicated with the drain outlet. Preferably, the water side heat exchanger is a titanium tube heat exchanger 20, wherein the water inlet temperature sensor 102 is used to detect the temperature of the pool, and preferably, a filtering device 25 is arranged at the water inlet end of the circulating water pump 21, which is used to filter impurities in the water to prevent the impurities from entering the water circulation pipeline and causing blockage.

[0035] The refrigerant side of the heat pump unit is provided with a compressor 12, a fin heat exchanger 23, a capillary tube 24, a heat exchange fan 22 and a titanium tube heat exchanger 20, and a refrigerant pipeline communicated with the compressor 12, the fin heat exchanger 23, the capillary tube 24 and the titanium tube heat exchanger 20; the heat exchange fan 22 is arranged at the opposite side of the fin heat exchanger 23.

In addition, the heat pump unit further comprises a back gas sensor 104 arranged at the inlet of the compressor 12 and an exhaust sensor 105 arranged at the outlet of the compressor 12.

[0036] The working principle of the heat pump unit is as follows: the circulating water pump 21 sucks the low-temperature water in the pool through the water inlet of the water circulation pipeline, injects the low-temperature water into the titanium tube heat exchanger 20, exchanges heat with the high-temperature and high-pressure refrigerant on the refrigerant side in the titanium tube heat exchanger 20, and outputs the heated low-temperature water to the pool through the water outlet, so as to circulate and increase the temperature of the pool.

[0037] The air pump unit comprises an air pump 30 and an air exhaust pipeline, and the air exhaust pipeline is provided with an electric valve 4 and is in communication with the bubble outlet. The air pump 30 is used for inputting the generated gas into the air exhaust pipeline, and the electric valve 4 is used for forming an openable or closable through hole, wherein the through hole is used for being opened or closed to form the bubbles.

[0038] In one embodiment, the control board is used for entering the heat pump operation mode when the pool temperature detected by the water inlet temperature sensor is less than the set temperature, in the heat pump operation mode, the control board closes the air pump unit, starts the heat pump unit, and starts the circulating water pump 21 to circulate and heat the water in the pool through the water circulation pipeline.

[0039] In addition, the control board is also used for entering the air pump operation mode when the pool temperature detected by the water inlet temperature sensor 102 is greater than or equal to the set temperature, in the air pump operation mode, the control board closes the heat pump unit, starts the air pump unit, and starts the air pump 30 and opens the electric valve 4. The control board is provided with a computer program for switching the heat pump operation mode and the air pump operation mode according to the pool temperature and the set temperature, so as to ensure that the water temperature of the pool is maintained in a relatively stable range during use.

[0040] In another embodiment, the control board is used for obtaining the ambient temperature and the pool temperature, and controlling the operating frequency of the air pump 30 according to the ambient temperature and the pool temperature, wherein the operating frequency of the air pump 30 is directly proportional to the ambient temperature and the pool temperature, so that the interval time of the bubbles generated by the air pump 30 is shorter when the ambient temperature or the pool temperature is higher.

[0041] In a specific example, the control board obtains a preset ambient temperature interval in which the ambient temperature is located, and a preset pool temperature interval in which the pool temperature is located, and obtains a preset frequency of the air pump 30 according to the preset ambient temperature interval and the preset pool temperature interval, and controls the air pump 30 to operate according to the preset frequency; wherein the preset frequency is greater when the preset pool temperature interval is greater under the same preset ambient temperature interval, and / or the preset frequency is greater when the preset ambient temperature interval is greater under the same preset pool temperature interval.

[0042] As shown in the following table, in a specific implementation, the operating load (i.e. operating frequency) of the air pump 30 is directly proportional to the ambient temperature and the pool temperature.

[0043]

[0044] In another embodiment, the control board is further configured to control the frequency of the opening and closing of the through hole of the electric valve 4 according to the ambient temperature and the pool temperature, so as to control the size of the bubbles generated, wherein the diameter of the through hole opened and closed by the electric valve 4 is inversely proportional to the ambient temperature and the pool temperature respectively, so that the higher the ambient temperature or the pool temperature, the larger the bubbles generated by the air pump 30.

[0045] In a specific example, the control board is configured to obtain a preset ambient temperature interval in which the ambient temperature is located, and obtain a preset pool temperature interval in which the pool temperature is located, and obtain the frequency of the opening and closing of the through hole of the electric valve 4 according to the preset ambient temperature interval and the preset pool temperature interval, and control the electric valve 4 to open and close the through hole according to the preset frequency; wherein, in the same preset ambient temperature interval, the larger the preset pool temperature interval, the smaller the frequency of the opening of the through hole of the electric valve 4; and / or, in the same preset pool temperature interval, the larger the preset ambient temperature interval, the smaller the frequency of the opening of the through hole of the electric valve 4. The control board is configured to obtain a preset ambient temperature interval in which the ambient temperature is located, and obtain a preset pool temperature interval in which the pool temperature is located, and obtain the diameter of the through hole opened by the electric valve 4 according to the preset ambient temperature interval and the preset pool temperature interval, and control the electric valve 4 to open according to the preset frequency; wherein, in the same preset ambient temperature interval, the larger the preset pool temperature interval, the larger the diameter of the through hole opened by the electric valve 4; and / or, in the same preset pool temperature interval, the larger the preset ambient temperature interval, the smaller the frequency of the opening of the through hole of the electric valve 4.

[0046] In a specific example, the electric valve 4 comprises an electric motor 6, a first gear and a second gear are sleeved on the electric motor 6, the first gear and the second gear are different in size and number of teeth; a fine opening disc 7 is sleeved on the first gear, and a coarse opening disc is sleeved on the second gear, a plurality of small holes 71 are formed on the fine opening disc, and a plurality of large holes 81 are formed on the coarse opening disc, when the electric motor 6 rotates, the fine opening disc and the coarse opening disc rotate at different speeds respectively, so that the large holes 81 and the small holes 71 can be superimposed during rotation, so that the frequency of the opening of the through hole of the electric valve 4 is the frequency of the channel formed by the superposition of the two disc openings.

[0047] In the preferred embodiment, the electric motor 6 is used to drive the fine perforated disc 7 and the coarse perforated disc 8 to rotate at different speeds through the first gear and the second gear, so that the passages formed by the perforations between the fine perforated disc 7 and the coarse perforated disc 8 are constantly and rapidly closed and opened to form bubbles. Under the condition that the operating power of the air pump 30 is constant, the passages formed by the fine perforated disc and the coarse perforated disc will be constantly and rapidly closed and opened due to the rapid rotation, and the air passing through the passages will be cut into a small section. Therefore, the faster the rotation speed of the electric motor 6, the more frequent the air is cut into sections, the smaller the air flow group, and the smaller the generated bubbles. Thus, the size of the bubbles can be adjusted by adjusting the operating frequency of the electric motor 6 to adjust the frequency of the open holes of the electric valve 4, so as to adjust the size of the bubbles.

[0048] The bubble generating device of the pool machine provided by the application is based on an air source heat pump pool machine, and a new set of air pump devices is built in. The heat pump system and the air pump 30 system work independently, and are intelligently controlled through a built-in control board. According to different pool temperature environments, the bubble generating device can automatically switch to a heat pump operation mode or an air pump operation mode, so that users can enjoy the effect of constant-temperature hot water massage at any time and anywhere in an outdoor environment. According to the environmental temperature and the water temperature, the bubble generating device adjusts the size and frequency of the generated bubbles, so as to achieve a better massage effect.

[0049] The above-described embodiments only express several embodiments of the application, and the description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the patent. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the application, a number of modifications and improvements can be made, which are all within the protection scope of the application.
