In some embodiments of the present application, the steam generating device 2 is mounted in a kitchen or a toilet. It may be understood that the steam generating device 2 is required to be supplemented with water in time, and a water source is often provided in the kitchen or the toilet; the steam generating device 2 is mounted in the kitchen or the toilet, such that the steam generating device 2 may be closer to the water source, thereby reducing a water supplementing difficulty, and improving a work reliability of the steam generating device 2.
In some embodiments of the present application, the steam generating device 2 may be hung from a ceiling or a wall, thus reducing an occupied space of the steam generating device 2, and meanwhile lowering a mounting difficulty thereof, so as to be beneficial to improving a mounting efficiency of the steam generating device 2. It should be noted that the steam generating device 2 in the present application may be sold and mounted separately.
In some embodiments of the present application, as shown in Figs. 6 and 7, the steam generating device 2 includes: a working water tank 22 provided with a heating cavity 222, the heating cavity 222 being communicated with the steam chamber 221, and the steam chamber 221 being located inside or outside the heating cavity 222; and an electric heater 25 provided in the heating cavity 222.
The electric heater 25 has the advantage of a stable heating power, thus avoiding a rapid change (rapid increase or rapid decrease) of a quantity of the steam generated by a heating process, and usage of the electric heater 25 has the advantage of gently adjusting a humidity, thereby improving the comfort of the user.
It may be understood that the electric heater 25 heats the water in the water tank, the water is evaporated at a high temperature to generate steam, the steam may be collected in the steam chamber 221, and when the pressure of the steam collected in the steam chamber 221 is higher than the pressure at the steam outlet 224, under the action of the steam pressure, the steam in the steam chamber 221 may sequentially flow through the steam outlet 224 and the steam delivery line 3, and then is conveyed into the indoor unit 1, and delivered to the indoor space along with air flow in the indoor unit 1.
The heating cavity 222 serves as not only a place for containing water to be heated, but also a reaction place for heating water by the electric heater 25. The steam chamber 221 serves as not only a place for collecting the steam, but also a place for accumulating the pressure of the steam, and by providing the heating cavity 222 and the steam chamber 221, the steam pressure may be quickly raised to a working pressure, thereby improving the working performance of the air conditioning device 100.
For example, in some examples of the present application, two working water tanks 22 are provided, and two electric heaters 25 are provided in one-to-one correspondence to the two working water tanks 22.
Specifically, the steam outlet 224 is provided in the working water tank 22, and communicated with the steam chamber 221 inside the working water tank 22.
In some embodiments of the present application, the electric heater 25 is configured as a PTC thermistor. The PTC thermistor is a semiconductor resistor typically having a temperature sensitivity, and the arrangement of the PTC thermistor may guarantee heating power of the electric heater 25 to further increase a generation rate of the steam, thereby reducing a response time of the steam generating device 2. Furthermore, compared to other types of electric heaters 25, the PTC thermistor is highly safe and less likely to cause ignition, or the like, even when heated dryly.
Specifically, the PTC thermistor has adjustable actual power, and during actual operation, the power of the PTC thermistor may be controlled as required. In addition, the PTC thermistor is highly sensitive to temperature, and when the water in the working water tank 22 is insufficient or used up, this condition may be learned in time according to the temperature of the PTC thermistor.
Specifically, a plurality of PTC thermistors are provided at intervals. The plurality of PTC thermistors may further increase the production rate of the steam to further reduce the response time of the steam generating device 2. The plurality of PTC thermistors may be spaced apart in a height direction of the working water tank 22, and thus, a water level in the working water tank 22 may be judged according to the operating temperatures of the plurality of PTC thermistors.
In some embodiments of the present application, a plurality of electric heaters 25 are provided. The plurality of electric heaters 25 may further increase the production rate of the steam to further reduce the response time of the steam generating device 2.
In some embodiments of the present application, as shown in Figs. 6 and 7, the working water tank 22 has a drainage port 225. It may be understood that, during long-term operation of the steam generating device 2, the water inside the working water tank 22 is heated and evaporated into steam by the electric heater 25 for a long time. Since impurities, such as chloride ions, calcium ions, or the like, in the water are hardly taken away by the steam, these impurities may have concentrations higher and higher under long-term accumulation, and thus corrode not only the working water tank 22, but also other detecting elements in the working water tank 22, which influences an operation reliability of the steam generating device 2. The Impurities brought in the water tend to be scaled in the working water tank 22, and the thicker a scale layer, the more difficult the removal. In addition, the steam in the working water tank 22 inevitably carries water mist with impurities during discharge, and when the content of the impurity in the water is too high, the sprayed water mist also influences health of people. Thus, the working water tank 22 is required to be cleaned periodically, and by providing the drainage port 225, cleaned sewage may be drained out of the working water tank 22 through the drainage port 225, thereby improving cleanliness of the working water tank 22.
Furthermore, when the working water tank 22 is required to be repaired or an emergency occurs and the water in the working water tank 22 is necessary to be drained, the water in the working water tank 22 may be drained through the drainage port 225. Specifically, the drainage port 225 is provided in a bottom of the working water tank 22 and may be connected with a sink or bathroom equipment through a drainage pipe, the water discharged from the working water tank 22 may automatically flow into the sink or a urinal by gravity, and a drainage valve 23 is further provided at the drainage port 225.
In some embodiments of the present application, as shown in Figs. 6 and 7, the air conditioning device 100 (referring to Fig. 1) further includes: a water supplementing tank 26 communicated with the water source; and a communicating pipe 27 having one end communicated with the water supplementing tank 26 and the other end communicated with the working water tank 22. The water supplementing tank 26 may be configured to timely deliver and supplement water to the working water tank 22, and the problem that the working water tank 22 is unable to be supplemented with water due to temporary water cut may be solved by providing the water supplementing tank 26, such that the working water tank 22 may still work continuously during short-time water cut, thereby improving the working reliability and safety of the air conditioning device 100.
For example, in some examples of the present application, one water supplementing tank 26 is provided, and a plurality of working water tanks 22 are provided and communicated with the water supplementing tank 26 through the communicating pipes 27 respectively.
For another example, in some examples of the present application, a plurality of water supplementing tanks 26 are provided, a plurality of working water tanks 22 are provided, and the plurality of water supplementing tanks 26 are fitted with the plurality of working water tanks 22 in one-to-one correspondence.
In some embodiments of the present application, as shown in Figs. 6 and 7, the communicating pipe 27 is configured as a U-pipe. It may be understood that after the water supplementing tank 26 is communicated with the working water tank 22 through the U-pipe, a liquid level in the water supplementing tank 26 is flush with a liquid level in the working water tank 22, when the working water tank 22 has a low liquid level, the water supplementing tank 26 also has a relatively low liquid level, and when the working water tank 22 has a high liquid level, the water supplementing tank 26 also has a relatively high liquid level. Thus, the liquid level in the working water tank 22 may be controlled within an appropriate range by controlling the liquid level in the water supplementing tank 26.
In some embodiments of the present application, as shown in Figs. 6 and 7, a one-way valve 28 is provided at the U-pipe to enable fluid to flow only from the water supplementing tank 26 to the working water tank 22, thus avoiding that the water in the working water tank 22 flows back into the water supplementing tank 26 under the action of the high-pressure steam, and meanwhile avoiding that the steam in the working water tank 22 flows back into the water supplementing tank 26, so as to guarantee uniqueness of a flowing direction of the steam in the working water tank 22. It should be noted that the one-way valve 28 enables the fluid to flow only from the water supplementing tank 26 to the working water tank 22, and meanwhile may prevent the steam in the working water tank 22 from flowing back into the water supplementing tank 26.
It should be noted that, in order to guarantee the working safety of the steam generating device 2, the water supplementing tank 26 may be set to deliver and supplement water to the working water tank 22 only when no steam is generated in the working water tank 22. Or, when an air pressure in the working water tank 22 is the same as an air pressure in the water supplementing tank 26, the water supplementing tank 26 delivers and supplements water to the working water tank 22.
In some embodiments of the present application, as shown in Figs. 6 and 7, the water supplementing tank 26 has a ball cock 261 for controlling communication or disconnection between the water supplementing tank 26 and the water source. It may be appreciated that when the liquid level in the water supplementing tank 26 is below a preset height, the ball cock 261 may control the water source to be communicated with the water supplementing tank 26, thus replenishing the water supplementing tank 26 with water; when the liquid level in the water supplementing tank 26 reaches the preset height, the ball cock 261 controls the water source to be disconnected from the water supplementing tank 26. Thus, by providing the ball cock 261, the water supplementing tank 26 may be communicated with the water source in time under the condition that the water supplementing tank 26 is short of water, and disconnected from the water source in time under the condition that the water supplementing tank 26 is not short of water.
It may be understood that, during operation of the air conditioning device 100 according to the embodiment of the present application, an electric heating device in the steam generating device 2 may heat the water in the working water tank 22 to generate the steam, and when the pressure of the steam in the working water tank 22 is higher than the pressure at the steam outlet 224, under the action of the steam pressure, the high-pressure steam in the working water tank 22 may sequentially flow through the steam outlet 224 and the steam delivery line 3, and then be conveyed into the indoor unit 1, and delivered to the indoor space along with the air flow in the indoor unit 1.
When the working water tank 22 has a small amount of water, the water supplementing tank 26 may replenish water into the working water tank 22 through the communicating pipe 27, and when the liquid level in the water supplementing tank 26 is lower than the set height, the ball cock 261 may control the water supplementing tank 26 to be communicated with the water source, thereby replenishing water into the water supplementing tank 26. Specifically, the water supplementing tank 26 may be connected with a faucet through a water inlet pipe, and the faucet is turned on when the water supplementing tank 26 is required to be supplemented with water.
In some embodiments of the present application, the water supplementing tank 26 is in communication with a water source in the kitchen or toilet, which may be either tap water or purified water, thus lowering a mounting difficulty of the water supplementing tank 26, and meanwhile reducing a distance between the water supplementing tank 26 and the water source, and achieving convenient and practical advantages.
In some embodiments of the present application, the water supplementing tank 26 may include a water tank body and a water inlet valve, the water tank body has an outer wall integrally provided with a mounting base and is provided with a water inlet, and the water inlet valve is mounted to the mounting base and connected with the water inlet.
Specifically, when mounted at the water tank body, the water inlet valve is fitted with the mounting base to reliably fix the water inlet valve, which is beneficial to improving a working reliability of the water inlet valve; meanwhile, the mounting base and the water inlet valve are integrally formed, which is beneficial to guaranteeing a structural strength between the water tank body and the mounting base, realizes convenient formation and simple fabrication, and omits redundant assembling parts and connecting processes, thus facilitating an improvement in an assembling efficiency of the water supplementing tank 26.
In some embodiments of the present application, the water supplementing tank 26 further includes a detection device provided within the water tank body, the water tank body has a water overflow port, the detection device is configured to send a water overflow signal when the water level within the water tank body is above a preset water level, and the water inlet valve is closed when the detection device sends the water overflow signal. It may be understood that the signal is transmitted between the detection device and the water inlet valve, and when the detection device outputs the water overflow signal, the water inlet valve is closed, so as to ensure that the water overflow amount of the water supplementing tank 26 is not too large, which is beneficial to improving the working reliability of the water supplementing tank 26.
In some embodiments of the present application, as shown in Figs. 1 and 2, the steam outlets 224 are in one-to-one correspondence to the steam delivery lines 3. It may be understood that, when a plurality of steam outlets 224 are provided, a plurality of steam delivery lines 3 are also provided, thus not only facilitating reduction of connection and mounting difficulties of the plural steam delivery lines 3 and the plural steam outlets 224, but also reducing repairing and later maintenance difficulties, saving mounting and later maintenance time, and improving mounting and repairing efficiencies.
For example, three steam outlets 224 are provided, three steam delivery lines 3 are provided, and the three steam outlets 224 are in one-to-one correspondence to the three steam delivery lines 3.
In some embodiments of the present application, as shown in Figs. 6 and 7, the working water tank 22 has an air pressure adjustment port 223 communicated with the heating cavity 222. The steam outlet 224 of the steam generating device 2 is communicated with the steam delivery line 3, the steam delivery line 3 (referring to Figs. 1 and 2) may have some bent sections, and after the steam delivery line 3 works for a long time, the bent sections tend to collect cooling water, which may block the flow of the steam and meanwhile cause an excessive air pressure in the steam delivery line 3 and the working water tank 22. By providing the air pressure adjustment port in the working water tank 22, the steam or the cooling liquid with the excessive air pressure in the steam delivery line 3 may be released periodically or when required, thereby improving steam delivery smoothness. Moreover, the pressure between the working water tank 22 and the water supplementing tank 26 may be balanced to ensure that the water supplementing tank 26 may timely replenish water into the working water tank 22.
It should be noted that, when the working water tank 22 stops working, the air pressure in the working water tank and the air pressure in the water supplementing tank may be kept balanced, but the steam delivery line 3 (referring to Figs. 1 and 2) may have some bent sections, and after the steam delivery line 3 works for a long time, the bent sections tend to collect cooling water, which may block the flow of the steam and meanwhile cause an excessive air pressure in the steam delivery line 3 and the working water tank 22; the arrangement of the air pressure adjustment port 223 may timely balance the pressure between the working water tank 22 and the water supplementing tank 26, thereby ensuring that the water supplementing tank 26 may timely replenish water into the working water tank 22.
In some embodiments of the present application, as shown in Figs. 6 and 7, a steam valve 24 is provided at the air pressure adjustment port 223. By providing the steam valve 24, the user may adjust the pressure of the steam in the steam delivery line 3 (referring to Figs. 1 and 2) and the working water tank 22 more conveniently. In addition, the arrangement of the steam valve 24 may further ensure that the steam in the steam chamber 221 does not leak when the steam generating device 2 works, thereby guaranteeing the working reliability and safety of the steam generating device 2.
Specifically, the steam valve 24 may be configured as a mechanical valve or an electromagnetic valve, and when the steam generating device 2 operates normally, the steam valve 24 is in a closed state.
In some embodiments of the present application, as shown in Figs. 1 and 2, the indoor units 1 are in one-to-one correspondence to the steam delivery lines 3. It may be understood that, when a plurality of indoor units 1 are provided, a plurality of steam delivery lines 3 are also provided, thus not only facilitating reduction of connection and mounting difficulties of the plural indoor units 1 and the plural steam delivery lines 3, but also reducing repairing and later maintenance difficulties, saving mounting and later maintenance time, and improving mounting and repairing efficiencies. Moreover, accurate air supply to different indoor units 1 may be realized, for example, when part of the indoor units 1 have large working air volumes, steam volumes of the corresponding steam delivery lines 3 may be adjusted to be adapted to the air volumes of the indoor units 1, which achieves the advantage of accurate humidification control.
According to some embodiments of the present application, as shown in Fig. 8, the other end of the steam delivery line 3 is located at the air outlet 11. It may be understood that, when the pressure of the steam in the working water tank 22 is higher than the pressure at the steam outlet 224, under the action of the steam pressure, the high-pressure steam in the working water tank 22 may sequentially flow through the steam outlet 224, the steam delivery line 3 and the air outlet 11 of the indoor unit 1 (referring to Figs. 6 and 7), and be mixed with the air flow delivered to the air outlet 11 by the indoor unit 1, so as to be conveyed to the indoor space together.
