[0026] Embodiments of the present disclosure will be described in more detail with reference to the drawings.

[0029] It should be noted that the modification of "one" or "multiple" mentioned in the present disclosure is illustrative rather than limiting, and those skilled in the art should understand that, unless otherwise explicitly indicated in the context, it should be understood as "one or more".

[0030] The existing top-mounted double-air-port warm-air bath heater using PTC heating mode can only provide warm air and normal temperature air during use, and cannot provide cold air lower than outdoor temperature. In summer, normal temperature air cannot meet the demand for comfort. The air conditioner using a compressor for refrigeration and heating is not only expensive, but also heavy, and cannot be directly mounted on the keel of the suspended ceiling like the warm-air bath heater, but can only be installed in the way of ceiling hanging pole, increasing the difficulty of on-site installation. Although some warm-air bath heaters use semiconductor refrigerating fins, the cold-dissipating end and the heat-dissipating end are in close contact with the refrigerating fin, resulting in serious limitation of the air port position, and actual product application difficulty.

[0031] To address the aforementioned problems, this disclosure provides a bathroom heater and a control method for controlling the bathroom heater disclosed herein.

[0032] Figure 1 This is a schematic diagram of the structure of a bathroom heater according to an embodiment of this disclosure, as shown below. Figure 1 As shown, the bathroom heater includes a cover 1, a housing 2, a blower 3, a semiconductor cooling device 4, and a ventilation fan 5. The housing 2 includes a blower duct 21 and a ventilation duct 22. The semiconductor cooling device 4 has the following structure: Figure 2 and Figure 3 As shown. Combined with Figures 1-3 As can be seen, the semiconductor cooling device 4 of the bathroom heater disclosed herein includes a semiconductor cooling chip 41, a heat dissipation end heat pipe module 42, and a cooling end heat pipe module 43. The semiconductor cooling chip 41 is disposed inside the bathroom heater housing and is not in the air duct. The heat dissipation end heat pipe module 42 is disposed inside the bathroom heater housing and includes a heat dissipation substrate 421, a heat transfer heat pipe 422, and a heat sink 423. The heat sink 423 is placed in the air exchange duct 22 of the bathroom heater, and the heat transfer heat pipe 422 connects the heat dissipation substrate 421 and the heat sink 423. The cooling end heat pipe module 43 is disposed inside the bathroom heater housing and includes a cooling substrate 431, a cooling heat pipe 432, and a cooling fin 433. The cooling fin 433 is placed in the air blowing duct 21 of the bathroom heater, and the cooling heat pipe 432 connects the cooling substrate 431 and the cooling fin 433. The heat pipe module 42 at the heat dissipation end and the heat pipe module 43 at the cooling end tightly press the semiconductor cooling chip 41 together in the middle using fasteners such as screws or springs.

[0033] In this disclosed semiconductor cooling device, the heat dissipation substrate 421 of the heat pipe module 42 at the heat dissipation end is attached to the heating surface of the semiconductor cooling chip 41, and the heat sink is placed in the ventilation duct 22. The heat transfer heat pipe 422 connects the heat dissipation substrate 421 and the heat sink 423. The heat dissipation substrate 431 of the heat pipe module 43 at the cooling end is attached to the cooling surface of the semiconductor cooling chip 41, and the cooling chip 433 is placed in the air blowing duct 21. The heat transfer heat pipe 432 connects the cooling substrate 431 and the cooling chip 433. The cooling substrate 431 and the heat dissipation substrate 421 are respectively pressed onto the cooling and heating surfaces of the semiconductor cooling chip 41 by fasteners such as screws or springs. The cooling and heating surfaces of the semiconductor cooling chip 41 are coated with thermal adhesive or thermal film to enhance heat transfer.

[0034] The bath heater of the present disclosure is a double-air port bath heater, including a blowing port and a ventilation port, and the blowing port is a cold air emitting end. When cold air needs to be blown in the room, the blowing fan 3 and the ventilation fan 5 are first started, and then the semiconductor refrigeration device 4 is started to operate, the refrigeration surface starts to generate cold energy, which is transmitted to the cold emitting fin through the cold emitting heat pipe, and then the cold energy is exchanged through the blowing air duct, so that cold air is blown out; at the same time, the semiconductor heating surface generates heat, which is transmitted to the heat emitting fin through the heat emitting heat pipe, and then the heat is exchanged through the ventilation air duct, so that the heat is discharged outside through the ventilation air duct. When hot air needs to be blown in the room, only the current direction of the semiconductor refrigeration fin needs to be changed, so that the refrigeration and heating surfaces are switched, thereby realizing the switching of cold air and hot air. The above can be realized by electronic control mode or mechanical control mode. When the blowing of cold air or hot air needs to be stopped, the power supply of the semiconductor refrigeration fin device is first cut off, and the blowing fan 3 and the ventilation fan 5 continue to operate for a period of time and then stop, or continue to operate in the blowing mode or the ventilation mode according to the user's instruction.

[0035] The control method of the bath heater provided by the embodiment of the present disclosure is further explained below, which is used to control the above-mentioned bath heater.

[0036] Figure 4 The flowchart of the control method of the bath heater provided by an embodiment of the present disclosure is shown in the figure, which can be executed by the control device of the bath heater provided by the embodiment of the present disclosure. The device can be realized by software and / or hardware, and can be integrated in the bath heater as shown in the figure. The bath heater includes a semiconductor refrigeration device. Figure 1

[0037] As shown in the figure, the control method of the bath heater can include the following steps: Figure 4

[0038] Step 201, in response to detecting that the current working mode of the bath heater is the cooling mode, obtaining a preset first expected temperature and a current first environment temperature.

[0039] Among them, the first expected temperature is the temperature set by the user for the cooling mode.

[0040] ​​Generally, the bathroom heater is configured with a controller such as a control panel or a remote controller, the controller has a function button such as a blowing function button, an air exchange function button, a high temperature adjustment function button, a low temperature adjustment function button, and a temperature display panel, when a user sets a desired temperature through the high temperature adjustment function button or the low temperature adjustment function button, the temperature display panel is used to display the temperature set by the user; during the working process of the bathroom heater, the temperature display panel is used to display the latest indoor temperature, that is, the ambient temperature; in the standby state of the bathroom heater, the temperature display panel is used to display the current ambient temperature, at this time, the ambient temperature can be obtained from the temperature sensor on the remote controller or the bathroom heater host, or from the local temperature data obtained from the network. When using the bathroom heater, in the standby state or blowing process of the bathroom heater, the user can control the bathroom heater to enter a temperature rising mode and set a desired temperature of the bathroom heater through the high temperature adjustment function button, and control the bathroom heater to enter a temperature falling mode and set a desired temperature of the bathroom heater through the low temperature adjustment function button, that is, a desired temperature; if the user only presses the blowing function button without pressing the temperature adjustment (high temperature adjustment or low temperature adjustment) function button, the bathroom heater operates in a default low wind mode and works in a natural wind blowing mode. After the user sets, the control device of the bathroom heater can obtain the current working mode of the bathroom heater and the corresponding desired temperature.

[0041] In this embodiment, when the bathroom heater enters the temperature falling mode, the control device of the bathroom heater can obtain the current desired temperature (for the convenience of description and distinction, referred to as a first desired temperature) and obtain the current ambient temperature (for the convenience of description and distinction, referred to as a first ambient temperature).

[0042] Step 202, determining a first temperature difference between the first ambient temperature and the first desired temperature.

[0043] Generally, when the ambient temperature is high, the user expects to lower the indoor temperature to improve comfort, in this case, the desired temperature set by the user is usually lower than the ambient temperature, therefore, in the temperature falling mode, after obtaining the first desired temperature and the first ambient temperature, the first ambient temperature is subtracted from the first desired temperature to obtain a temperature difference (for the convenience of description and distinction, referred to as a first temperature difference) between the ambient temperature and the desired temperature.

[0044] Step 203, in response to the first temperature difference being greater than a first preset value, controlling the air exchange motor, the blowing motor and the semiconductor refrigeration device of the bathroom heater to operate.

[0045] The first preset value can be set according to actual needs, for example, the first preset value is set to 3 degrees Celsius.

[0046] In this embodiment of the present disclosure, after the first temperature difference is determined, it can be compared with the first preset value, if the first temperature difference is greater than the preset first preset value, the air exchange motor and the blowing motor of the bathroom heater are controlled to operate, and then the semiconductor refrigeration device is controlled to operate. By controlling the semiconductor refrigeration device to operate, the bathroom heater can blow cold air.

[0047] The control method of the bath heater according to the embodiments of the present disclosure, by setting a semiconductor refrigeration device in the bath heater, when the bath heater works in the cooling mode, the expected temperature and the current environment temperature are obtained, if the environment temperature is higher than the expected temperature by a preset value, the ventilation motor and the blowing motor of the bath heater are controlled to run, and the semiconductor refrigeration device is controlled to run, thereby enabling the bath heater to blow cold air, so as to provide cold air lower than the outdoor temperature, meeting the user's demand for comfort in the hot weather in summer.

[0048] It can be understood that after the semiconductor refrigeration device is controlled to run, the bath heater blows cold air, and the indoor temperature will gradually decrease. In an optional embodiment of the present disclosure, during the running of the semiconductor refrigeration device, the control device of the bath heater can obtain the current indoor temperature (referred to as the first indoor temperature for the sake of distinction and description) in real time or periodically, and compare the first indoor temperature with the first expected temperature, calculate the difference (referred to as the second temperature difference for the sake of distinction and description) between the first expected temperature and the first indoor temperature, if the second temperature difference is greater than the first preset value, it is determined that the indoor temperature has met the set demand, at this time, the semiconductor refrigeration device can be controlled to stop running, and the ventilation motor stops running, while the blowing motor continues to maintain the running state. Thus, it can be avoided that the indoor temperature is too low to affect the user's comfort, and the user is chilled.

[0049] Further, after only the blowing motor runs, the indoor temperature will gradually rise. In order to ensure that the indoor temperature meets the user's setting demand, the indoor temperature needs to be monitored to reduce the temperature again when the indoor temperature rises to a certain extent. Therefore, in an optional embodiment of the present disclosure, during the continuous running of the blowing motor, the current indoor temperature (referred to as the second indoor temperature for the sake of distinction and description) can be obtained in real time or periodically, and the second indoor temperature is compared with the first expected temperature, the difference (referred to as the third temperature difference for the sake of distinction and description) between the second indoor temperature and the first expected temperature is calculated, and then the third temperature difference is compared with a second preset value, wherein the second preset value is less than the first preset value. If the third temperature difference is not less than the second preset value, the ventilation motor is controlled to run, at this time, the ventilation motor and the blowing motor are both in the running state, and the semiconductor refrigeration device is not running. Thus, by setting the second preset value less than the first preset value, when the indoor temperature is at least higher than the first expected temperature by the second preset value, the ventilation motor is continued to run, which can ensure timely blowing and avoid the user's body feeling too high, thereby improving the user's comfort.

[0050] In an optional embodiment of the present disclosure, if the determined first temperature difference is greater than 0 and not greater than the first preset value, it is determined that the temperature difference between the current room temperature and the first expected temperature is not large at this time, and in this case, only the ventilation motor and the blowing motor of the bath heater can be controlled to operate, and the semiconductor refrigeration device is not operated. Thus, the semiconductor refrigeration device can be controlled to be turned off when the temperature difference is not large, thereby ensuring user comfort while saving energy consumption.

[0051] Further, in an optional embodiment of the present disclosure, based on the foregoing embodiments, after the blowing motor and the ventilation motor of the bath heater are controlled to operate and the semiconductor refrigeration device is controlled to not operate, timing can be started, for example, a timer can be started to time, and a timing duration is obtained. If the room temperature (for the sake of description and distinction, referred to as third room temperature) at the time when the timing duration reaches the first preset duration is greater than the first expected temperature, the semiconductor refrigeration device is controlled to operate, at this time, the ventilation motor, the blowing motor and the semiconductor refrigeration device of the bath heater are all in the operating state, and this operating state is maintained until the first expected temperature is higher than the room temperature by the first preset value, and then the semiconductor refrigeration device is controlled to stop operating and the ventilation motor is controlled to stop operating, and only the blowing motor continues to operate. The first preset duration can be pre-set according to actual needs. Thus, when the room temperature is still greater than the first expected temperature after the blowing motor and the ventilation motor operate for the first preset duration, the semiconductor refrigeration device is turned on to blow cold air, thereby accelerating the decrease of the room temperature, so that the user can obtain comfortable temperature as soon as possible, and the user experience is improved.

[0052] Further, in an optional embodiment of the present disclosure, after only the ventilation motor and the blowing motor operate, the latest room temperature can be detected in real time or periodically during timing, and if the room temperature is not greater than the first expected temperature when the timing duration does not reach the first preset duration, the ventilation motor is controlled to stop operating, at this time, only the blowing motor is in the operating state, and the blowing motor is maintained to operate until the room temperature is higher than the first expected temperature by the second preset value, and then the ventilation motor is controlled to operate, at this time, the ventilation motor and the blowing motor are both in the operating state, and the semiconductor refrigeration device is in the non-operating state. Thus, by timely closing the ventilation motor when the room temperature is detected to be lower than the first expected temperature, the user comfort can be ensured while saving energy consumption.

[0053] In an optional embodiment of the present disclosure, as shown in FIG. 6, the control method of the bath heater of the present disclosure can further include the following steps: Figure 5

[0054] Step 301, in response to detecting that the current working mode of the bath heater is the heating mode, obtaining a preset second expected temperature and a current second environment temperature.

[0055] ​The second expected temperature is a temperature set by a user for the temperature increasing mode.

[0056] As described above, the shower heater is configured with a controller such as a control panel or a remote controller, and the controller has function buttons such as a blowing button, an air exchange button, a high temperature adjusting button, and a low temperature adjusting button. During standby or blowing of the shower heater, the user can control the shower heater to enter the temperature increasing mode and set a desired temperature of the shower heater by using the high temperature adjusting button.

[0057] In the embodiment, when the shower heater enters the temperature increasing mode, the control device of the shower heater can obtain a current expected temperature (referred to as a second expected temperature for ease of description and differentiation) and obtain a current environment temperature (referreded to as a second environment temperature for ease of description and differentiation).

[0058] In step 302, a fourth temperature difference between the second expected temperature and the second environment temperature is determined.

[0059] Generally, when the environment temperature is low, the user expects to increase the temperature in the room to improve comfort. In this case, the expected temperature set by the user is usually higher than the environment temperature. Therefore, in the embodiment of the present disclosure, after the second expected temperature and the second environment temperature are obtained in the temperature increasing mode, the second expected temperature can be subtracted from the second environment temperature to obtain a temperature difference (referred to as a fourth temperature difference for ease of description and differentiation) between the environment temperature and the expected temperature.

[0060] In step 303, in response to the fourth temperature difference being greater than a third preset value, the blowing motor and the PTC heater of the shower heater are controlled to operate, and the PTC heater operates in a second warm air gear.

[0061] The third preset value can be set according to actual needs, for example, the third preset value is set to 3 degrees Celsius.

[0062] In the embodiment of the present disclosure, after the fourth temperature difference is determined, the fourth temperature difference can be compared with the third preset value. If the fourth temperature difference is greater than the third preset value, the blowing motor and the PTC heater of the shower heater are controlled to operate, and the PTC heater operates in the second warm air gear. The PTC heater includes a first warm air gear and a second warm air gear. The first warm air gear is a weak warm gear, and the second warm air gear is a strong warm gear. The heating intensity of the second warm air gear is greater than that of the first warm air gear. The PTC heater is composed of a PTC ceramic heating element and an aluminum pipe, and has the advantages of small thermal resistance and high heat exchange efficiency. In the embodiment, by starting the PTC heater to operate in the second warm air gear when the room temperature is low, the room temperature can be quickly increased, and the comfort of the user can be improved.

[0063] The control method of the bath heater according to the embodiments of the present disclosure, by acquiring the expected temperature and the current ambient temperature when the bath heater works in the heating mode, if the ambient temperature is lower than the expected temperature by a preset value, controlling the blowing motor of the bath heater to operate, and controlling the PTC heater to operate in the second warm air gear, thereby enabling the bath heater to blow strong warm air, accelerating the heating speed, and improving the comfort of the user.

[0064] Further, in an optional embodiment of the present disclosure, during the operation of the PTC heater in the second warm air gear, the current latest room temperature (denoted as the fourth room temperature for the convenience of description and differentiation) can be acquired in real time or periodically, and the acquired fourth room temperature is compared with the second expected temperature, if the fourth room temperature is not less than the second expected temperature, the PTC heater is controlled to switch from the second warm air gear to the first warm air gear, the heating intensity of the first warm air gear is lower than that of the second warm air gear, so that the PTC heater operates in the weaker first warm air gear to reduce the heating speed of the room temperature, thereby ensuring that the room temperature meets the user's expectation while saving energy consumption.

[0065] Further, when the room temperature is detected to be not less than the second expected temperature for the first time, the timing can be started, if the duration of the room temperature being not less than the second expected temperature is greater than the second preset duration, the PTC heater is controlled to stop operating, wherein the second preset duration can be preset according to the actual demand. That is, if the room temperature can be maintained to be higher than the second expected temperature for the second preset duration, the PTC heater is closed; if the room temperature is lower than the second expected temperature at a certain time within the second preset duration, the PTC heater is still maintained to operate in the first warm air gear, and the timing is restarted, until the room temperature is continuously higher than the second expected temperature for the second preset duration, the PTC heater is closed. Thus, the user's comfort can be ensured while saving energy consumption.

[0066] It can be understood that after the PTC heater is turned off, the room temperature will gradually decrease, in order to avoid the low room temperature affecting the user comfort, the room temperature can be monitored to increase the temperature when the room temperature is low to a certain extent. Thus, in an optional embodiment of the present disclosure, the current indoor temperature (for ease of description and differentiation, referred to as the fifth room temperature) can be obtained in real time or periodically, and the fifth room temperature is compared with the second expected temperature, the difference (for ease of description and differentiation, referred to as the fifth temperature difference) between the second expected temperature and the fifth room temperature is calculated, and the fifth temperature difference is compared with the fourth preset value, if the fifth temperature difference is greater than the fourth preset value, the PTC heater is controlled to run in the first warm air gear, wherein the fourth preset value is less than the third preset value. That is, after the PTC heater is turned off, when the room temperature decreases below the second expected temperature and the temperature difference between the room temperature and the second expected temperature reaches the fourth preset value, the PTC heater is started to run in the first warm air gear with weak warm air, thereby the room temperature can be increased in time when the room temperature is low, and the user comfort is ensured while the energy consumption is saved.

[0067] In an optional embodiment of the present disclosure, if the fourth temperature difference between the second expected temperature and the second environment temperature is greater than 0 and not greater than the third preset value, the blowing motor of the bath heater is controlled to run, the PTC heater is controlled to run, and the PTC heater runs in the first warm air gear, the heating intensity of the first warm air gear is lower than that of the second warm air gear, and the air exchange motor of the bath heater does not run. Thus, when the room temperature is lower than the expected temperature but the temperature difference is not large, the bath heater is controlled to run with weak warm air to increase the temperature, the user comfort is ensured while the energy consumption is saved.

[0068] Further, in an optional embodiment of the present disclosure, on the basis of the foregoing embodiments, after the PTC heater is controlled to run in the first warm air gear, the timing can be started, for example, a counter can be started to time, and the room temperature (for ease of description and differentiation, referred to as the sixth room temperature) when the timing duration reaches the third preset duration is obtained, if the sixth room temperature is less than the second expected temperature, the PTC heater is controlled to switch from the first warm air gear to the second warm air gear, at this time, the blowing motor of the bath heater keeps running, the air exchange motor still keeps stopping, the PTC heater runs in the second warm air gear, and the PTC heater continues to run in the second warm air gear until the second expected temperature is not greater than the room temperature, and then the PTC heater is switched from the second warm air gear to the first warm air gear. The third preset duration can be preset according to actual needs. Thus, when the room temperature is still less than the second expected temperature after the PTC heater is started to run in the first warm air gear for the first preset duration, the PTC heater is started to run in the second warm air gear, the room temperature is increased quickly, and the user can obtain comfortable temperature as soon as possible, and the user experience is improved.

[0069] Furthermore, in one optional embodiment of this disclosure, after controlling the PTC heater to operate at the first warm air setting, the latest room temperature can be detected in real time or periodically during the timing process. If the room temperature is detected to be not lower than the second desired temperature before the third preset time period has elapsed, the PTC heater stops operating. At this time, only the blower motor remains running and continues to operate until the room temperature is lower than the second desired temperature by a fourth preset value, at which point the PTC heater is controlled to operate at the first warm air setting again. Thus, by promptly shutting off the PTC heater when the detected room temperature is higher than the second desired temperature, energy consumption can be saved while ensuring user comfort.

[0070] Figure 6 This is a flowchart illustrating a control method for a bathroom heater according to a specific embodiment of the present disclosure. In this embodiment, the room temperature (i.e., ambient temperature) is denoted as t0, the desired temperature is denoted as t1, the first preset value and the third preset value are both set to 3, the second preset value and the fourth preset value are both set to 2, the first preset duration is denoted as n1, the third preset duration is set to n2, and the second preset duration is set to n3. Figure 6 As shown, when the bathroom heater is in standby, blowing, or ventilation mode, the user can adjust the temperature to enter cooling mode by lowering the temperature button, or to enter heating mode by raising the temperature button, and obtain the desired temperature t1. In cooling mode, the desired temperature is usually lower than the room temperature, while in heating mode, the desired temperature is usually higher than the room temperature. Therefore, the desired temperature t1 is compared with the room temperature t0. When the desired temperature t1 is greater than the room temperature t0, the heating control logic on the left is activated; when the desired temperature t1 is not greater than the room temperature t0, the cooling control logic on the right is activated.

[0071] In the temperature reduction control logic, if the expected temperature t1 meets 0 < t0-t1≤3 (i.e. the first preset value), the blowing motor and the ventilation motor are both started to run, and the semiconductor refrigeration device is not operated. Then, the system detects t0 every interval n0 (n0 is a preset period), and when t0≤t1 is met during the first preset time n1 (i.e. the timing duration does not reach n1), the ventilation motor stops running. If t0≤t1 is not met after the time n1 is reached, the semiconductor refrigeration device is started to run, until t1-t0≥3, the semiconductor refrigeration device stops running, the ventilation motor stops running, and the blowing motor continues to run. When t0-t1≥2 (i.e. the second preset value) is reached, the above logic of t1 meeting 0 < t0-t1≤3 is executed again. If the expected temperature t1 meets t0-t1>3, the ventilation motor runs, the blowing motor runs, and then the semiconductor refrigeration device runs, until t1-t0≥3, the semiconductor refrigeration device stops running, the ventilation motor stops running, and the blowing motor continues to run. Then, when t0-t1≥2 is reached, the above logic of t1 meeting 0 < t0-t1≤3 is executed again. The above logic is executed in a loop until the system receives other operation instructions (which can be system timing automatic stop, human detection of people leaving for a certain time automatic stop, manual switching of the working state to stop, etc.).

[0072] In the temperature rising control logic, if the expected temperature t1 meets 0 < t1-t0≤3 (i.e. the third preset value), the PTC heater is controlled to run in the weak heating mode (i.e. the first heating mode), the blowing motor runs but the air exchange motor is kept stopped, in this process, the ambient temperature t0 rises, the system detects t0 every preset period, when t1≤t0 is met during the third preset time n2 (i.e. the timing duration does not reach n2), the PTC heater is stopped; then, the room temperature t0 gradually decreases, when t1-t0≥2, the corresponding logic is run again according to the condition that t0 meets 0 < t1-t0≤3. If t1≤t0 is not met after the time n2 is reached, the PTC heater runs in the strong heating mode (i.e. the second heating mode), until t1≤t0, then the PTC heater runs in the weak heating mode, when t1≤t0 is met during the second preset time n3, the PTC heater is stopped. If the expected temperature t1 meets t1-t0>3, the PTC heater runs in the strong heating mode, then the system detects t0 every preset period, until t1≤t0, the PTC heater runs in the weak heating mode, when t1≤t0 is met during the second preset time n3, the PTC heater is stopped, the blowing motor continues to run; after the PTC heater is stopped and the blowing motor continues to run, t0 is continuously detected, when t1-t0≥2, the corresponding logic is run again according to the condition that 0 < t1-t0≤3, the above logic is run in a loop until the system receives other operation instructions (which can be system timing automatic stop, human sensing detection that a person leaves for a certain time, manual switching of the working state, etc.).
