Description

Water humidifier

Technical field

The invention relates to household appliances, in particular to a water humidifier.

Background technique

The traditional humidifier includes a base and a water tank buckled on the base. Between the water tank and the atomization chamber of the base, there are electromagnetic valves, floats and other components that control water entering the atomization chamber. Therefore, the traditional humidifier realizes hot mist. / Warm fog is relatively easy. For example, Chinese patent application CN2016214020645 discloses a warm-fog humidifier, which has a water tank and a heating tank on the base of the bag, the water tank is in communication with the water tank, and a bypass channel is provided between the water tank and the heating tank. A water tank replenishes water in the heat generating tank through the bypass channel. The circuitous method is used to replenish water, and there is no direct contact between hot and cold water, which reduces heat exchange, prevents heat loss and water tank overflow, and improves heating efficiency and product reliability. But like CN 2016214020645 The description of paragraphs 25-27 shows that: ① the water tank needs to be removed from the base, and the water tank nut needs to be unscrewed to add water to the water tank, which is cumbersome to use and inconvenient to use; Causes no water or too much water to cause overflow. Therefore, this type of humidifier that needs to remove the water tank to add water has been gradually phased out. Instead, a humidifier has been added in recent years. Opening the top cover of the humidifier can easily add water to the water tank. It is easy to use and gets more and more. The more consumers agree and love.

For the water humidifier, the atomizing element is directly located at the bottom of the water tank. There is no need to use water outlet valves and other components to control the water from the water tank to enter the atomization chamber. Therefore, if the existing water humidifier is to achieve hot mist / The warm fog function is nothing more than the following technical solutions:

The first solution is to add hot water to the water tank of the humidifier or even boiled water after high temperature sterilization. The added hot water gradually cools down during use, which prevents the effective and stable provision of hot mist. This solution is not convenient. User operation.

The second solution is to set the heating device on the side wall of the humidifier's fogging channel (such as the technical solution disclosed in Chinese patent CN2010202435151). Obviously, the contact area between the water mist and the heating device is small, so the heat conduction is not easy to cause Water mist heating efficiency is not high, and its ability to provide hot mist is very limited.

The third solution is to install a heating device at the bottom of the water tank to heat the water in the water tank and then atomize it. The disadvantage of this structure is that the hot mist can be generated only after the water in the entire water tank needs to be heated. Higher power consumption and lower heating efficiency.

Beneficial effect

The invention has the following beneficial technical effects:

1. Can generate hot mist quickly and quickly, low energy consumption (energy saving) and high heating efficiency

① Since the present invention only heats the cold water in the heating chamber to a predetermined temperature, it is not necessary to simultaneously heat the entire cold water in the water tank to a predetermined temperature, so that the humidifier can provide a hot mist of a preset temperature or a short time after it is turned on. Warm fog has the advantage of generating hot fog quickly and quickly. ② Because only the cold water entering the heating chamber is heated, the water in the atomization chamber is continuously consumed by the source, so that the water source in the heating chamber is continuously replenished to the atomization chamber under the effect of atmospheric pressure, so that the hot water in the heating chamber and the water tank The heat loss due to heat exchange between cold water is small, the energy consumption required for heating is relatively low, and the heat loss is small, so it has the advantage of energy saving.

热雾的出雾量大，加湿效果佳。The hot fog has a large amount of fog, and the humidification effect is good.

On the one hand, the invention guides the heat of the heating cavity into the atomizing cylinder by providing a guide groove, supplementing the heat of the thermal mist on the upper end of the atomizing cylinder, and reducing the condensation of the thermal mist into water droplets due to heat loss before it is discharged from the humidifier. Falling down can reduce the loss of hot mist, and at the same time, the hot mist with higher heat can be dispersed farther after being discharged from the humidifier, which is conducive to improving the humidification capacity of the humidifier; on the other hand, a water introduction cover is provided at the upper end of the atomizing cylinder With the water diversion cover, the air flow from the air outlet channel is blocked into the water tank outside the atomization tube, and the water mist in the atomization tube is quickly set by setting a fog guide hole on the water diversion cover and even a windshield surrounding the fog guide ability. Guided to be discharged from the mist guide hole, the water mist will not be accumulated in the atomization cylinder or spilled into the water tank outside the atomization cylinder, so the mist guiding ability is strong and the amount of mist is large; even by setting in the atomization chamber The energy-gathering ring increases the amount of fogging out of the humidifier and meets the requirements for a stable amount of fogging out at high water levels in the water tank.

Embodiments of the invention

In order to further explain the technical means and effects adopted by the present application to achieve the intended purpose, the detailed implementation, structure, features, and effects according to the present application are described in detail below with reference to the drawings and preferred embodiments. In the following description, different "one embodiment" or "an embodiment" does not necessarily mean the same embodiment. Furthermore, the particular features, structures, or characteristics in one or more embodiments may be combined in any suitable form.

As shown in FIG. 1 to FIG. 3, the humidifier proposed by the present invention includes a water tank 9, and the inner bottom surface of the water tank 9 is provided with atomizing elements 92 independent of each other (the atomizing element 92 preferably uses an existing ultrasonic atomizing sheet / (Transducer) and heating element 93 (the heating element 93 preferably uses an existing PTC (Positive Temperature Coefficient) heater); the lower end surface is connected to the atomized energy-saving cover of the water tank 9.

Further combined with FIG. 4 and FIG. 5. The atomizing energy-saving cover comprises: an isolation cover 1 provided with an open lower end surface, and a lower end surface of the isolation cover 1 separates a first cavity 2 and a second cavity 3 which are independent from each other. The second cavity 3 has a second cold water inlet. The water inlet 31 and the hot water outlet 32, the second cavity 3 communicates with the outside of the isolation cover 1 through the second cold water inlet 31, and the first cavity 2 has a hot water inlet 21 communicating with the hot water outlet 32; A cavity 2 extends upwardly to provide a mist guide tube 20; the second cavity 3 has a guide groove 38 extending upwardly along the mist guide tube 20, and the inner side wall of the guide groove 41 connected to the mist guide tube 20 is provided with a guide. A notch 411 (see FIG. 3) communicating with the mist cylinder 20.

Among them, the atomizing cylinder 20 and the first cavity 2 are integrally provided; of course, the atomizing cylinder 20 and the first cavity 2 can also be detachably disposed, that is, the lower end of the atomizing cylinder 20 is threaded or A detachable structure such as a buckle is connected to the first cavity 2. In addition, the position of the hot water outlet 32 of the second cavity 3 is not lower than the position of the second cold water inlet 31 of the second cavity 3, so that the hot water in the second cavity 3 can be smoothly heated from the heat. The water outlet 32 flows out to the first cavity 2.

The lower end surface of the isolation cover 1 is connected to the inner bottom surface of the water tank 9. Specifically, the lower end edge of the second cavity 3 is connected to the inner bottom surface of the water tank 9 around the heating element 93 and the heating element 93 is located at the bottom of the second cavity 3, so that the second cavity 3 and the inner bottom surface of the water tank 9 are formed. The heating cavity communicates with the water tank 9 outside the isolation cover 1 through the second cold water inlet 31, so that the water in the water tank 9 enters the heating cavity from the only channel of the second cold water inlet 31; the first cavity 2 The lower end surface is connected to the inner bottom surface of the water tank 9 around the atomizing element 92 and the atomizing element 92 is located at the bottom of the first cavity 2, so that the atomizing cavity is formed between the first cavity 2 and the inner bottom surface of the water tank 9. It directly communicates with the water tank 9 but communicates with the heating chamber through the hot water inlet 21, and indirectly communicates with the water tank 9 through the heating chamber; the heat of the heating chamber is guided upward by the guide groove 38, and the heat is transmitted through the groove 411 Conducted to the atomizing cylinder 20 to provide heat supplement to the hot mist above the atomizing cylinder 20.

In addition, a portion of the isolation cover 1 above the second cavity 3 is provided as an inclined inclined cover 16, that is, the end position of the inclined cover 16 away from the guide groove 38 is lower than the inclined cover 16 near the guide groove 38. The end position is beneficial to let the heat in the heating chamber enter the guide groove 38 along the inclined cover 16.

The connection between the lower end surface of the isolation cover 1 and the inner bottom surface of the water tank 9 means that the lower end surface of the isolation cover 1 and the inner bottom surface of the water tank 9 are hermetically connected or approximately hermetically connected or incompletely hermetically connected. In the present invention, the lower end surface of the isolation cover 1 and the inner bottom surface of the water tank 9 are preferably connected in a sealed manner. This is because, of course, when the lower end face of the isolation cover 1 and the inner bottom surface of the water tank 9 are in an approximately sealed state or incompletely sealed, there may be a small amount of cold water leaking into the atomizing chamber during use, and there is also partial heat in the heating chamber. The situation where water leaks to the water tank 9 may thereby increase the energy consumption of the heating element 93. In addition, in one embodiment, in order to connect the lower end edge of the isolation cover 1 to the inner bottom surface of the water tank 9 and reduce installation difficulty, the inner bottom surface of the water tank 9 is provided with a mounting groove matching the lower end surface of the isolation cover 1 and may be installed in the mounting groove. Set a seal ring in the. When the atomizing energy-saving cover is installed on the inner bottom surface of the water tank 9 from the upper opening of the water tank 9, only the lower end edge of the isolation cover 1 needs to be inserted into the installation groove on the inner bottom surface of the water tank 9 (after installation, as shown in FIG. 3). It is simple and convenient for subsequent maintenance when the atomizing energy-saving cover is removed from the inner bottom surface of the water tank 9.

Further, as shown in FIG. 5, a bypass passage 13 is provided between the second cold water inlet 31 of the second cavity 3 and the first cold water inlet 11 of the isolation cover 1, and the bypass passage 13 and the inner bottom surface of the water tank 9 A circuitous supplementary water channel is formed between the peripheral edges of the second cavity 3. Specifically, the bypass passage 13 includes: a first cold water inlet 11 provided on the isolation cover 1, the first cold water inlet 11 communicating with the second cold water inlet 31 of the second cavity 3; The enclosure 12 between the lower end of the cover 1 and the second cavity 3 forms a connection between the enclosure 12 and the lower end of the partition cover 1 between the first cold water inlet 11 and the second cold water inlet 31. The detour channel 13 is provided around the periphery of the second cavity 3. Therefore, the cold water enters the bypass channel 13 from the first cold water inlet 11 of the isolation cover 1, passes through the bypass channel 13 and flows into the heating chamber from the second cold water inlet 31. The present invention provides a circuitous supplementary water path at the front end of the second cold water inlet 31 of the heating cavity, and the technical effect brought to the entire technical solution is that the cross-sectional area of the circuitous channel 13 in contact with the heating cavity is small, which can reduce the heating cavity. Heat is transferred to the water tank 9 through the bypass passage 13.

Because the cold water in the water tank 9 cannot directly enter the atomizing chamber, it must pass through the heating chamber to enter the atomizing chamber. The heating element 93 in the heating chamber works to heat and sterilize the cold water in the heating chamber, and the hot water enters the mist from the heating chamber. After the cavity is formed, the atomizing element 92 vibrates the hot water in the atomizing cavity to form a hot mist, and the hot mist is collected in the mist guide tube 20; and the guide groove 38 guides the heat of the heating chamber upward and passes through the slot opening 411 conducts heat to the atomizing cylinder 20 so as to provide heat supplement to the hot mist above the atomizing cylinder 20 to ensure that the thermal mist is minimized to reduce the temperature during the process of the upper end of the atomizing cylinder 20 to the exclusion of the humidifier to reduce the formation of hot mist and condensation. The return of water droplets to the atomizing chamber can also allow the hot mist with a higher temperature to be dispersed further after being discharged from the humidifier, thereby improving the humidifying ability and the humidifying effect.

In order to quickly discharge the hot mist in the upper end of the atomizing cylinder 20 from the humidifier, the humidifier is also provided with an air duct structure, which includes: an air duct 91 provided on the inner side wall of the water tank 9, and the air duct 91 There is a fan inside; the upper end of the atomizing cylinder 20 is provided with an air inlet 201 communicating with the air guide tube 91; and the water introduction cap 8 is provided at the upper end of the water tank 9 (or above the atomizing cylinder 20). There are a plurality of drain holes 82 for allowing water to flow into the water tank 9. A position of the water introduction cover 8 corresponding to the atomizing cylinder 20 is provided with an upper convex portion 81 protruding from the drain hole 82. The upper convex portion 81 A mist guiding hole 811 is provided on the misting cylinder 20. The fan works to generate airflow in the air guide tube 91. The airflow enters the mist guide tube 20 from the air inlet 201 and causes the air pressure in the mist guide tube 20 to rise. The airflow drives the hot mist in the mist guide tube 20 from the mist guide hole 811 of the water introduction cover 8. Drain quickly.

In combination with the embodiment shown in FIG. 6 and FIG. 7, the air inlet 201 of the atomizing cylinder 20 is further provided with an air guide groove 202 communicating with the air guide pipe 91, and the airflow of the air guide pipe 91 is passed through the air guide groove 202. It is introduced into the atomizing cylinder 20. In order to allow the airflow of the air guide tube 91 to enter the atomizing cylinder 20 as much as possible to ensure that there is sufficient wind pressure to ensure the mist output ability of the humidifier, the lower end of the water introduction cover 8 needs to prevent the airflow of the air guide tube 91 from entering as much as possible. The water tank 9 outside the atomizing tube 20 enters into the atomizing tube 20 through the air guide groove 202 as much as possible, and the upper end of the atomizing tube 20 and the water tank 9 are separated as much as possible to reduce the chance of air flow interaction. Therefore, In one embodiment, the lower end surface of the water introduction cover 8 is in close contact with the upper end surface of the atomizing cylinder 20. Alternatively, designing the air guiding structure to guide the air pressure of the atomizing cylinder 20 to the mist holes 811 can also ensure that there is sufficient wind pressure to ensure the fogging ability of the humidifier. In the embodiment shown in FIG. 1, the lower end face of the water introduction cover 8 faces downward. A wind deflector 83 is extended, and the wind deflector 83 extends into the atomizing cylinder 20, wherein the upper convex portion 81 is located above the wind deflector 83, the upper convex portion 81 is semi-spherical, and a plurality of fog guiding holes 811 are uniform. The arc-shaped outer surface of the upper convex portion 81 is distributedly distributed, so that the air pressure of the atomizing cylinder 20 is guided to the upper fog guide hole 811 through the wind deflector 83. The practice has proved that the wind deflector 83 guides the airflow very well and atomizes The water mist above the cylinder 20 can quickly overflow from the mist guide hole 811 without being accumulated in the atomizing cylinder 20 or overflowing into the water tank 9 outside the atomizing cylinder 20.

In addition, when water needs to be added to the water tank 9, the water is directly poured on the water introduction cover 8. Since the position of the drain hole 82 is lower than the position of the mist guide hole 811, the water falls through the drain hole 82 into the water tank 9 below, thereby achieving Easy operation with water. Of course, in order to prevent foreign matter from entering the water tank 9 or to make the overall appearance of the humidifier more beautiful, a water tank cover 95 may be provided at the upper end of the water tank 9, and the water tank cover 95 is provided with an outlet communicating with the mist guide hole 811. The mist hole 951, therefore, the water mist overflows from the mist guide hole 811 and sprays the water mist through the mist outlet hole 951 for humidification.

A typical application scenario of the water humidifier (also referred to as "humidifier") proposed by the present invention is as follows: When the humidifier is not powered on, the user opens from the top of the water tank 9 or from the water introduction cover 8 shown in FIG. 1. Cold water can be added to the water tank 9 by pouring water, and the cold water passes through the first cold water inlet 11, the second cavity 3 (or heating cavity), and the hot water circulation area 4 into the first cavity 2 (or atomizing cavity) in order. Under the effect of atmospheric pressure, the height of the water level in the water tank 9 is consistent with the height of the water level in the atomizing cylinder 20 of the atomizing chamber. When the humidifier is set to work, the water temperature needs to be heated to 80 ° C. At time t0, the user turns on the power of the humidifier. The atomizing element 92 and the heating element 93 are all powered to start working. The heating element 93 starts to heat but the atomizing chamber cannot be immediately turned on. The cold water inside is heated to 80 ° C, and the temperature of the water in the heating chamber is gradually increased. At the same time, the cold water in the atomizing chamber is atomized due to the operation of the atomizing element 92, and the water in the heating chamber is automatically replenished to the atomizing chamber under the effect of atmospheric pressure. Until time t1, the temperature of the water in the atomizing chamber reaches 80 ° C, and then a hot mist is generated through the atomizing element 92 and the hot mist is sequentially ejected from the mist guide hole 811 of the water introduction cover 8 and the mist outlet hole 951 of the water tank cover 95. According to the description of the above typical application scenario, compared with the prior art, which requires all the cold water in the water tank to be heated to 80 ° C to reach the predetermined water temperature, the present invention has at least the following beneficial technical effects: ① Since the present invention only uses the heating chamber The cold water can be heated to a predetermined temperature of 80 ° C, and the cold water in the entire water tank 9 does not need to be heated to a predetermined temperature of 80 ° C at the same time, so that the humidifier can provide a preset temperature of hot or warm mist in a short time after it is turned on. It has the advantage that hot fog provides fast and fast. ② Since the heating chamber has a guide groove 38 extending upward along the atomizing cylinder 20, the heat emitted from the hot water in the heating chamber enters the guide groove 41 along the inclined casing 16 and guides the mist along the notch 411 of the guide groove 41 The hot mist in the cylinder 20 supplements the heat, so that the hot mist can be maintained at a high temperature, which can reduce the condensation and fall of the hot mist in the mist guide cylinder 20. Maintaining the high temperature of the hot mist can improve the ability of the hot mist to escape after being discharged from the humidifier. Improve the humidification capacity of the hot mist humidifier. ③ Because only the cold water entering the heating chamber is heated, the water in the atomizing chamber is continuously consumed by the source, so that the water source in the heating chamber is continuously replenished to the atomizing chamber under the effect of atmospheric pressure, so that the hot water in the heating chamber and the water tank 9 The heat loss caused by the heat exchange between the intercooled water is small, especially the heating cavity communicates with the water tank 9 through the circuitous supplementary water passage with a small cross-sectional area, so that the heat exchange between the heating cavity and the circuitous supplemental water passage is small, and the heating cavity and the The heat exchange between the circuitous supplemental waterway is actually preheating the cold water in the circuitous supplemental waterway near the heating cavity. This part of the preheated cold water also flows to the atomization cavity along with the hot water from the heating cavity. In the heating cavity, the heating cavity hardly transfers heat to the cold water in the water tank 9 and causes heat loss. Compared with the prior art, it is necessary to heat all the cold water in the water tank and continuously exchange hot water with external air to cause heat loss. In terms of energy consumption, it is obvious that the energy consumption required for heating is relatively low and the heating heat loss is small in the present invention.

In addition, during the use of the humidifier, the water tank 9 needs to be periodically cleaned to prevent the breeding of bacteria and improve the safety of use. Since the present invention forms the heating cavity and the atomizing cavity by installing the atomizing energy-saving cover on the inner bottom surface of the water tank 9, and the atomizing energy-saving cover can be easily and quickly removed from the inner bottom surface of the water tank 9, the water tank 9 can be conveniently connected. And atomized energy-saving hood for cleaning and maintenance, to meet the actual needs of users.

Furthermore, as shown in FIG. 3 and FIG. 6, in order to improve the atomizing ability of the humidifier, an energy-collecting ring 7 for collecting the vibration energy of the atomizing element 92 to improve the atomizing ability may be provided in the atomizing chamber. The energy-gathering ring 7 uses the existing technology (for example, the energy-gathering ring 7 is the "energy concentrator" mentioned in Chinese patent CN 2017204797680 or the "atomization enhancement part" mentioned in China CN2012105555089); even, in the atomization One or more guiding columns are also provided in the cavity, and the guiding columns provide a guiding function for the energy gathering ring 7 as the water surface in the atomizing cavity rises or falls.

The above are only preferred embodiments of this application, and are not intended to limit this application. Any modification, equivalent replacement, and improvement made within the spirit and principle of this application shall be included in the protection of this application. Within range.
