Description

Partitioned air supply control method of bathroom air conditioner

Technical Field

The invention relates to a partitioned air supply control method of a bathroom air conditioner.

Background

In the past, a toilet needs to be subjected to dry-wet separation. When a person takes a shower in a bathroom, a large amount of water vapor exists in the bathroom, and the damp and hot water vapor is condensed on the surface of the cold bathroom wall ceramic tile, so that clothes are easily wetted. After showering, humid air remains in the toilet for a long time, causing air pollution, and water vapor is easily condensed on the surfaces of ceilings, walls, mirrors, cabinets, electrical appliances, and the like. In the past, the risk of mold growth, bacterial growth, short circuit, and the like in the area, furniture, electric appliances, and the like was easily caused. In the prior art, the dry and wet separation of the toilet is usually realized by partitions, shower rooms, doors, shower curtains and the like.

In addition, a person may feel cold or stuffy depending on the season or the stage of the shower while taking a shower. In order to ensure that the ambient temperature and humidity are appropriate when a person takes a shower, an air conditioner is installed in a toilet. The air conditioner installed in the toilet adjusts the temperature and humidity of the whole toilet to improve the use feeling of people.

(method for judging position of small-space host machine in kitchen and toilet)

In order to control different areas of the small space, it is necessary to set various control parameters (such as the air blowing direction, the air blowing amount, and the air blowing temperature) in the operation mode or the secondary operation mode based on the position of the main unit of the air conditioner with respect to the different areas of the small space, that is, to locate the main unit of the air conditioner. The basic principle of the positioning method of the main unit of the air conditioner is as follows.

The basic parameters of the small space are preset in the air conditioner, and certain initial air supply parameters are set.

When the air conditioner is started to supply air, the air supply of the air conditioner is rebounded by different wall surfaces of the small space and returns to the air return opening of the air conditioner, and the air supply motor drives the fan to enable the air to be supplied to the air outlet of the air conditioner through the air supply loop in the air conditioner. When the air is blown out, the air volume returned to the return air inlet of the air conditioner is different. In order to ensure that the air volume of the air outlet of the air conditioner is constant, the rotation speed of the air supply motor (power is increased) is required to make up the air volume lost due to on-way resistance, and therefore the position of the air conditioner can be judged according to the power increase percentage of the air supply motor.

When the path of the air outlet of the air conditioner returning to the air return inlet from the air outlet is completely free of the shielding object, the air outlet volume and the air return volume of the air conditioner can not cause air volume loss due to on-way resistance loss correspondingly. When the angle of the air outlet is changed, the air outlet volume and the air return volume of the air conditioner are set values (reference values), and the air conditioner is limited by the size of a small space due to the fact that the air conditioner is arranged in the small space, and the air flow of the air outlet is subjected to resistance along the way when flowing along the set direction. In this case, the return air volume is smaller than the reference air volume value (a certain percentage of the reference value) set without the shutter. The air conditioner generates a control signal according to the air volume percentage, and the control signal is fed back to the fan motor to enable the power of the fan motor to be changed. The air conditioner can determine the position of the air conditioner according to the values (power change values) before and after the change of the rotating speed of the fan motor, the collected air physical parameters (the physical parameters comprise the temperature, the humidity, the density, the specific heat capacity and the like of air), the blowing angle and the size of a toilet in the current environment.

Referring to fig. 3, a method for positioning a main unit of an air conditioner will be described. Fig. 3 is an explanatory diagram showing a method of determining the position of the kitchen and bath small space master. The small space in fig. 3 is divided into a first zone and a second zone. The partition shown in fig. 3 is merely an example, and is not limited to two areas, and may be three or more areas.

First, the space size of the small space is set in the initialization program of the air conditioner. The space size includes length, width and height.

Then, the air conditioner determines the position of itself in the small space in the direction of the front and rear air blowing. Specifically, as shown in the left diagram of fig. 3, the blade 23 for left and right air blowing of the air conditioner is set to be centered in the initialization routine, and the air direction of the air blowing is controlled only by the blade 23 for up and down air blowing, and at this time, the up and down air blowing angle and the air blowing amount of the air conditioner are set (the maximum range in which the air blowing angle α can be set is 0 ° to-90 °). When the angle is selected too small, the air supply volume is small and the test accuracy is insufficient, and when the angle is selected too large, the air flow scattering degree is too large and the test accuracy is also insufficient. Therefore, it is preferable that the upper and lower air supply angles are two air supply angles of 30 ° and 60 °, respectively (the two angles are designed air supply angles that most air conditioners can achieve in normal use and in general air conditioners). The relative position of the air conditioner in the front and rear air supply direction, that is, the position of the air conditioner from the front and rear walls is located by detecting the percentage value of the power rise of the fan motor at both air supply angles of 30 ° and 60 °.

Then, the air conditioner determines the position of itself in the small space in the direction of the left and right air blowing. Specifically, as shown in the right-hand diagram of fig. 3, the blade 23 for the air-conditioning upper and lower air blowing is set to be centered in the initialization routine, and the angle of the air blowing is controlled only by the blade 23 for the left and right air blowing, and at this time, the left and right air blowing angles and the air blowing amount of the air-conditioning are set (the maximum range in which the air blowing angle α can be set is 0 ° to-90 °). As in step S12, it is preferable that the left and right air blowing angles are two air blowing angles of 30 ° and 60 °, respectively. The relative position of the air conditioner in the direction of the left and right air supply (i.e., the position of the air conditioner from the left and right walls) is located by detecting the percentage value of the power rise of the fan motor at both the air supply angles of 30 ° and 60 °.

Therefore, the position of the air conditioner in the small space can be detected, and the position data is stored in the memory 7 and the cloud server 9 for subsequent setting and control.

(kitchen and toilet small space partition environment keeping control method)

In order to maintain the environment of a small space in a partitioned manner such as a kitchen, a toilet and the like, a kitchen and toilet small space partitioned environment maintaining control method is designed.

Next, a method for keeping and controlling the partitioned environment in the small space of the kitchen and the toilet will be specifically described.

In the method, the set parameters comprise: (1) the operation mode is a main mode of the air conditioner operation, including temperature rise and temperature reduction; (2) target partition, i.e. a certain partition which is pre-designated automatically or manually; (2) the operation air volume, namely the air volume mode and the air volume value of the air conditioner operation, comprises high air volume (75-100% of the total capacity), medium air volume (33-74% of the total capacity), low air volume (5-32% of the total capacity), and the air volume value in each air volume mode can be a specific value.

The specific flow of the kitchen and bathroom small space partition environment keeping control method is as follows.

First, a pretreatment is performed. The pretreatment is only needed to be executed once when being matched with the installation of an air conditioner. The pretreatment includes the following three aspects. The description will be made by taking a toilet as an example.

(1) And acquiring horizontal and vertical position information of the air conditioner according to a 'kitchen and bathroom small space host position judgment method'. The horizontal and vertical position information of the air conditioner may be manually set by a user or an installer. The cloud server 9 may also perform big data analysis to obtain the horizontal and vertical position information of the air conditioner. The horizontal and vertical position information of the air conditioner can be obtained by a laser distance sensor of the air conditioner.

(2) According to the 'horizontal and vertical position information of the air conditioner', for each target subarea, the pointing direction from the air conditioner to the target subarea with the air conditioner as the center of the sphere is calculated. The pointing direction of each target partition can also be obtained by a laser distance sensor of the air conditioner.

The positioning of the kitchen and bathroom air conditioner can be implemented by the method for judging the position of the small-space host computer in the kitchen and the bathroom. When each partition of the toilet is confirmed, each partition of the toilet can be selected in a display area of the external controller 8 of the air conditioner, the partition setting is set in a program in advance, and a user can select a proper partition mode according to the layout of the actual toilet. The partition mode selected by the user can be realized by selecting the spatial layout mode through a secondary menu. After confirming the air conditioner position and the layout of the toilet subareas, the direction of the air supply of each subarea by the air conditioner can be determined. According to the space position of the air conditioner and the wind direction of the air supply and exhaust of the air conditioner, the air supply and exhaust is rebounded by the wall surface and returns to the air return opening of the air conditioner after passing through the partition to be conveyed. Because the path of the air sent and exhausted has trigonometric function relation in the toilet space, the air supply angle of the air conditioner can be accurately controlled, and the air processed in the air conditioner is directionally sent to different subareas through the action of the air conditioner blades.

Take the case of dividing the toilet into four zones and supplying air to the toilet zone by the air conditioner. Fig. 4 is a schematic view of the path of the supply air for supplying air to the toilet bowl area. As shown in fig. 4, when the user selects to supply air to the toilet area at the external controller 10, the air conditioner automatically adjusts the direction of the blades, and the air of the air conditioner returns to the air return opening through the kitchen and toilet space.

(3) The position of the air conditioner in the toilet is known, and the blade angle in the case of the partition is also confirmed, and the temperature rise rate and the temperature fall rate of different partitions are set according to the change along with the outdoor environment. Namely, under the conditions that the outdoor temperature is relatively low in winter, relatively warm in spring and autumn and relatively hot in summer, the control processes of the heating rate and the cooling rate of the corresponding subarea are different, and the heating rate and the cooling rate are mainly in direct relation with the change of the frequency of the outdoor variable frequency compressor of the air conditioner along with the time.

In winter, the outdoor environment temperature is-20 ℃ to 10 ℃, the safety of the air conditioner operation is very important due to the low outdoor environment temperature, the pressure of the refrigerant in the whole system is relatively low, the fluidity of the compressor lubricating oil at low temperature is poor, the refrigerant and the lubricating oil cannot be well dissolved mutually at the moment, and the heat exchange efficiency is low. Therefore, the compressor is preheated for a period of time, so that the refrigerant and the lubricating oil flow through internal circulation for a period of time, the indoor fan is started in a delayed mode, and the frequency of the compressor is gradually increased by adopting a step-by-step frequency increasing mode to warm the toilet. The time-dependent temperature rise rate in the toilet is shown in fig. 5, and the safety of the compressor from the start to the stable operation can be ensured. Furthermore, when the air conditioner is operated in the winter season, attention is particularly paid to the case where the outdoor ambient temperature is particularly low. When the outdoor environment temperature is very low, the compressor is difficult to start, the pressure of the air suction port of the compressor needs to be paid special attention at this moment, and when the compressor runs at ultra-low temperature, if the pressure of the air suction port is too low, the frequency of the compressor should be properly reduced to meet the safe running of the air conditioner.

In spring and autumn, the outdoor environment temperature is 10-20 ℃. Because outdoor ambient temperature is moderate relatively, the body feels warm, so the restriction of compressor start-up this moment is less, and the compressor can directly start-up promptly, need not take hierarchical mode of raising frequency, can take the quick mode of raising frequency of straight line, can be according to the temperature that the user set for, and quick raising frequency guarantees user's experience and feels. The temperature rising rate and the temperature falling rate of the toilet are shown in the graphs of fig. 5 and 6 along with the time change.

In summer, the outdoor environment temperature is 20-40 ℃, and the limitation of the start of the compressor is less because the outdoor environment temperature is relatively hot, so that the indoor temperature can be quickly cooled by adopting a linear quick frequency increasing mode. However, when the frequency is increased to a certain value, the pressure of the refrigerant in the outdoor unit is high and the temperature of the discharge port of the compressor is also high, and the compressor needs to be operated in a frequency-reducing manner to ensure the safety of the air conditioner. A schematic diagram of the cooling rate of the toilet over time at this time is shown in fig. 6.

After the preprocessing, the following steps are performed each time the kitchen and bath small space partitioning environment keeping control method is operated.

(1) The pointing direction from the air conditioner to the target partition with the air conditioner as the center of sphere may be calculated in real time for each target partition based on "horizontal and vertical position information of the air conditioner" every time the kitchen and bath small space partition environment keeping control method is executed. Or the pointing direction of each target partition is obtained by a laser distance sensor of the air conditioner. That is, this step is performed when the kitchen and bath small space partitioning environment keeping control method is executed after the preprocessing, and is not performed in the preprocessing.

(2) And judging the running mode.

When the temperature is increased, the current environment mode is judged according to the indoor and outdoor temperature sensors and humidity sensors, or the current season, temperature and humidity information is acquired from the cloud end to judge the current environment mode.

When the mode is determined to be the spring and summer mode, the air-conditioning heating mode is turned on. At this time, the direction compensation value is corrected upward by 2 ° to 5 ° in the vertical direction so as to improve the user experience by utilizing the principle of the drop of the cool air.

When the mode is determined to be the autumn and winter mode, the air-conditioning heating mode is started. At this time, the direction compensation value is corrected by 2 to 5 degrees downward in the vertical direction, so that the use experience of the user is improved by using the principle that the hot air rises.

When the temperature is reduced, the current environment mode is judged according to the indoor and outdoor temperature sensors and the humidity sensor, or the current season, temperature and humidity information is acquired from the cloud end to judge the current environment mode.

When the mode is determined to be the spring and summer mode, the air-conditioning cooling mode is turned on. The direction compensation value is corrected to be 2-5 degrees upwards in the vertical direction so as to improve the use experience of a user by utilizing the principle of cold air descending.

When the mode is determined to be the autumn and winter mode, the air-conditioning heating mode is started. The direction compensation value is corrected to 2-5 degrees downwards in the vertical direction, so that the use experience of a user is improved by using the principle that hot air rises.

The above-described spring and summer mode and autumn and winter mode are merely names of modes and do not necessarily correspond to real seasons.

(3) And calculating the numerical value of the pointing direction of the air guide blade.

And the numerical value of the pointing direction of the wind guide blade is equal to the numerical value of the pointing direction of the target subarea plus the compensation value of the delta direction.

(4) And driving the air guide blades to point to the direction according to the numerical values of the pointing directions of the air guide blades.

(5) And starting an air supply motor, setting different operation powers according to the operation air quantity, and starting air supply according to the operation powers.

In addition, real-time feedback is also carried out when the control method for keeping the environment of the small space partition of the kitchen and the toilet is operated. The temperature of indoor outer temperature, humidity information and fine setting air supply can be obtained according to indoor outer temperature sensor and humidity transducer to realize comfortable user's body and feel the temperature. And the direction fine adjustment in a partition range can be realized by adjusting a delta direction compensation value through a human detection sensor.

As described above, the kitchen and bathroom small space partition environment keeping control method can calculate the matched air supply angle and automatically control the air conditioner according to the set mode, the designated partition and the running air volume, and can realize the surrounding type air flow circulation of the designated partition.

(control method for keeping regular environment in small space of kitchen and toilet)

In order to regularly maintain the environment of small spaces such as kitchens, toilets and the like, a regular environment maintaining control method for the small spaces of the kitchens and the toilets is designed.

The parameters required in the method include the time interval for the periodic start-up and the operating parameters for the periodic start-up.

The time interval of the regular start can be set by the user through the external controller 10 or the mobile phone APP, or can be automatically acquired from the cloud server 9 by the air conditioner, and the time interval of the regular start is set according to big data information such as region, season, temperature, humidity and the like.

The operating parameters of the regular start can be automatically acquired from the cloud server 9 by the air conditioner, and are set according to regions, seasons, temperatures, humidity and the like, including air volume, temperature and the like.

In the control method for maintaining the regular environment in the small space of the kitchen and the bathroom, whether the time interval is reached or not is automatically judged. When the time interval has not been reached, monitoring continues. And when the time interval is reached, operating the kitchen and bathroom air conditioner to perform dehumidification operation.

As described above, the periodic environmental conservation control method for the small space of the kitchen and the toilet can be automatically started periodically, so that the air conditioner can perform a corresponding environmental conservation program, thereby reducing the humidity in the small space range of the kitchen and the toilet and eliminating peculiar smell, controlling the temperature, and better realizing the effect of removing mildew.

The above description is of the special operation method of the air conditioner of the present invention, and the air conditioner of the present invention can naturally perform air direction and temperature control in the normal air-conditioning heating and cooling mode. These methods may be performed in different operating modes or in a secondary operating mode.

[ examples ]

The embodiment relates to a zone air supply control method of a bathroom air conditioner applied to a bathroom. Next, this embodiment will be explained.

(first installation of bathroom air conditioner)

The bathroom air conditioner used in the embodiment is partitioned during initial installation. The partition method includes the following two methods.

Firstly, according to the setting of a user, an installer respectively designates a plurality of directions pointed by air supply blades of the air conditioner through a switch on a bathroom air conditioner main body or a function menu of an external controller, and the plurality of directions correspond to areas set in a system program of the bathroom air conditioner one by one. For example, when the user faces the bathroom air conditioner main body, the left area of the user is set as a dry area, and the right area is set as a wet area. After the bathroom air conditioner obtains the setting information, the setting information is stored in a memory of the main body as fixed parameters of a daily operation mode.

Secondly, the user inputs partition information on, for example, a mobile phone APP, and the partition information is uploaded to the cloud server. The bathroom air conditioner acquires the partition information of the user area through the cloud server, and automatically completes the area division.

The zoning adopted by the embodiment can refer to fig. 6, and comprises a bathing area, a washing area, a closestool area and a clothes drying area. Wherein the bathing area is a wet area, and the washing area, the toilet area and the clothes drying area are dry areas.

The bathroom air conditioner has a configuration of software and hardware common to the kitchen air conditioner, and the setting of the operation mode as the bathroom air conditioner or the kitchen air conditioner is completed at the time of shipment, or the operation mode as the bathroom air conditioner or the kitchen air conditioner is set by an installer on site using a switch on the air conditioner main body or a function menu of an external controller.

The bathroom air conditioner is provided with an external controller. The external controller is a fixed panel or a remote control panel fixed on a wall surface or the like, and may be a touch screen Pad or an infrared remote controller, for example. The external controller is communicated with the air conditioner main body through the communication module. The external controller can start the air conditioner, select an operation mode, adjust the temperature, the air volume and the like of the air conditioner, reserve the operation of the air conditioner, control the OTA updating of programs and data in the memory, control the wireless network access setting and the like. Corresponding APP can be installed in the mobile phone to play the same control role as the external controller.

The operation modes of the bathroom air conditioner which can be selected through the external controller or the mobile phone APP comprise a bathing mode, a toilet mode, a mould removing mode, a dehumidifying mode and a clothes drying mode. After the user selects the operation mode, the bathroom air conditioner operates in the selected operation mode.

However, the operation mode of the bathroom air conditioner may be defaulted to the bathing mode. At this time, the front mode, the middle mode, and the rear mode are three different operation modes. When the operation mode of the bathroom air conditioner comprises a plurality of modes, the front mode, the middle mode and the rear mode are two-stage operation modes in the bathing mode.

The bathroom air conditioner is also provided with a wireless switching controller. The wireless switching controller is a portable and mountable controller for switching the mode of operation or the secondary mode of operation. The wireless switching controller can be communicated with the bathroom air conditioner main body. The wireless switching controller can also be communicated with an intelligent home router and an intelligent home gateway and can be accessed into a home Internet of things system.

Next, an operation mode and a two-stage operation mode in the air supply control method for the dry-wet separation zone of the bathroom air conditioner will be described.

<1. bathing mode >

The bathing mode comprises a front mode, a middle mode and a rear mode.

The front mode is a mode performed at a preparation stage from when a user does not enter the bathroom to when the user has entered the bathroom for bathing. In the front mode, the wind direction is controlled towards the dry zone and towards the person.

The middle mode is a mode executed in the stage that a user enters a wet area from a dry area to perform bathing. In the middle mode, the wind direction is controlled to face the dry area, and the wind direction faces the surface of wall tiles, mirror surfaces, houses and articles.
