referring to fig. 1, an embodiment of the present utility model provides a water heater 100, where the water heater 100 provided by the embodiment of the present utility model can be used by a user again without water cooling and heating, thereby improving the experience of the user.

In the embodiment of the present utility model, the water heater 100 includes a water inlet pipe 110, a first heating device 120, a water storage device 130, a second heating device 140 and a water outlet pipe 150, wherein the water inlet pipe 110 has a water inlet 112 for guiding external water from the water inlet 112 into the water inlet pipe 110; the first heating device 120 is connected with the water inlet pipe 110 and is used for heating water in the water inlet pipe 110; the water storage device 130 is connected with the water inlet pipe 110 and is used for storing water entering the water inlet pipe 110 through the water inlet 112; the second heating device 140 is provided in the water storage device 130 for heating the water in the water storage device 130 to a target temperature value; the water outlet pipe 150 is provided with a water outlet 152, and the water outlet pipe 150 is connected with the water storage device 130 and is used for guiding water in the water storage device 130 from the water outlet 152 to the outside of the water storage device 130.

The water storage device 130 is connected with the water inlet pipe 110, and the water in the water inlet pipe 110 flows into the water storage device 130 after being heated by the first heating device 120, is heated by the second heating device 140, and finally flows out of the water heater 100 from the water outlet pipe 150. During the starting process of the first heating device 120, a period of several seconds may be required, during which the first heating device 120 cannot heat the water in the water inlet pipe 110, the water in the water inlet pipe 110 directly flows into the water storage device 130, and the second heating device 140 heats the water in the water storage device 130 to a target temperature value, so that the temperature value of the water flowing out of the water outlet pipe 150 is always kept at the target temperature value. When the user uses water again in the use process, the condition that water is cooled and heated does not occur, so that the experience of the user is improved.

For example: the water heater 100 and the shower head are all hot water in the pipeline during the bathing process. If the shower is turned off in the middle and the shower is turned on again, the first heating device 120 is restarted, and a section of cold water is sent out to the water storage device 130 in the starting process, at this time, the water in the water storage device 130 is at the target temperature value, that is, the temperature value of the water flowing out from the water outlet pipe 150 is approximately at the target temperature value, and the condition of water cooling and heating is not caused, so that the experience of a user is improved.

The target temperature value may be factory-set or user-set, and may be slightly greater than or equal to the use temperature value set by the user.

In addition, in the embodiment of the present utility model, the water storage device 130 always holds water with a water temperature value within a range from a set temperature value to a target temperature value, and in the process of starting the water heater 100 for the first time, a few seconds are required from starting ignition to enabling the first heating device 120 to normally output hot water, in this process, the hot water is stored in the water storage device 130, and when cold water in a pipeline runs out, the hot water can be supplied through the water storage device 130, so that the time of supplying the cold water is reduced, the time of supplying the hot water is shortened, uncomfortable feeling of users caused by excessive cold water supplied in the ignition combustion heating time is avoided, and the user experience feeling is improved.

The water heater 100 further includes a housing 190, the first heating device 120, the second heating device 140, the water storage device 130, the water inlet pipe 110 and the water outlet pipe 150 are disposed in the housing 190, and the water outlet 152 and the water inlet 112 are disposed outside the housing 190.

Referring to fig. 1 and 2, in some embodiments, the water heater 100 further includes a first temperature sensor 160 and a controller 170, and the first temperature sensor 160 and the second heating device 140 are electrically connected to the controller 170; the first temperature sensor 160 is used for detecting the temperature value of the water temperature in the water storage device 130; the controller 170 is configured to receive the water temperature value and control the second heating device 140 to stop heating under the condition that the water temperature value is greater than or equal to the target temperature value.

The first temperature sensor 160 is disposed in the water storage device 130, and detects the water temperature value of the water in the water storage device 130, and after receiving the water temperature value detected by the first temperature sensor 160, the controller 170 controls the second heating device 140 to operate, if the water temperature value is greater than or equal to the target temperature value, which means that the water temperature value in the water storage device 130 is too high, the user may burn the skin during the bathing process, so that under the condition that the water temperature value is greater than or equal to the target temperature value, the controller needs to control the second heating device 140 to stop heating, so as to avoid the too high temperature value of the water flowing out of the water outlet 152.

The first temperature sensor 160 and the controller 170 are electrically connected, but may be communicatively connected. The first heating device 120 may be an electric heater.

In addition, in other embodiments, the water heater 100 may not include the controller 170, and the first temperature sensor 160 may be directly connected to the second heating device 140, and the power of the second heating device 140 is turned off to stop heating the second heating device 140 when the water temperature value is greater than or equal to the target temperature value. I.e. the second heating means 140 is controlled to be turned off under the condition that the water temperature value is greater than or equal to the target temperature value.

In some embodiments, the controller 170 is further configured to control the second heating device 140 to be activated when the water temperature value is less than or equal to a set temperature value, wherein the set temperature value is less than the target temperature value.

If the water temperature value is less than or equal to the set temperature value, it indicates that the water temperature value of the water storage device 130 is low, and if the user feels that the water temperature is low during use, the second heating device 140 should be controlled to be started at this time to heat the water in the water storage device 130 until the water temperature value is greater than or equal to the target temperature value.

That is, in some embodiments, the temperature of the water exiting the water outlet 152 is approximately between a set temperature value and a target temperature value, which are approximately temperature values that are more comfortable for the user to bath.

In some embodiments, the outlet pipe 150 has a communication port 154 in communication with the water storage device 130, and the first temperature sensor 160 is disposed proximate the communication port 154. The water in the water storage device 130 enters the water outlet pipe 150 through the conducting port 154 and is drained to the outside of the water heater 100 through the water outlet 152 of the water outlet pipe 150. The first temperature sensor 160 is disposed near the conducting port 154, and can accurately reflect the temperature value of the water flowing into the water outlet pipe 150, so that the temperature of the hot water flowing out of the water outlet pipe 150 can be within the range of the set temperature value and the target temperature value, and the accuracy of controlling the outlet water temperature of the whole water heater 100 is improved.

In the process of heating the water in the water storage device 130 by the second heating device 140, the water around the second heating device 140 is heated first, and then the water in other parts is heated by heat conduction. The water temperature value in the whole water storage device 130 is not necessarily uniform, and the situation that the local part is high and the local part is low may occur, and the first temperature sensor 160 is arranged close to the conducting port 154, that is, the first temperature sensor 160 is arranged near the conducting port 154, so that the water temperature value around the conducting port 154 can be accurately detected, and the water temperature value entering the water outlet pipe 150 can be ensured to be within the interval of the set temperature value and the target temperature value as far as possible.

Referring to fig. 1 and 3, in some embodiments, the water heater 100 further includes a second temperature sensor 180 connected to the controller 170; the second temperature sensor 180 is used for detecting the temperature value of the inlet water heated by the first heating device 120 through the inlet pipe 110; the controller 170 is used for adjusting the heating temperature of the first heating device 120 under the condition that the temperature value of the inlet water is greater than the preset temperature value.

The second temperature sensor 180 is disposed on the water inlet pipe 110 and is close to the water storage device 130, and is mainly used for detecting a temperature value of the inlet water heated by the first heating device 120, so that more cold water enters the water storage device 130 during the repeated starting process of the water heater 100, and under the condition that a temperature value of the water in the water storage device 130 is too low, the controller 170 controls the first heating device 120 to increase a heated temperature value, so that the temperature value of the water in the water storage device 130 can reach a set temperature value and a target temperature value as soon as possible. The second temperature sensor 180 is configured to detect a temperature value of the water fed by the first heating device 120 after heating, and if the temperature value of the water fed is too high, which indicates that the heating amount of the first heating device 120 is too high, the controller 170 may control the first heating device 120 to reduce the heating temperature, so that water in the water storage device 130 can be kept within a range between the set temperature value and the target temperature value as soon as possible.

For example: the water temperature value set by the user is 45 degrees, the set temperature value is 44 degrees, the target temperature value is 46 degrees, the water temperature value in the water storage device 130 is far less than 44 degrees in the initial starting process of the water heater 100, the preset temperature value can be set to be 50 degrees higher, the water temperature value in the water storage device 130 is quickly heated to be within the interval of 44 to 46 degrees, and the controller 170 controls the first heating device 120 to reduce the heating temperature if the water inlet temperature value of the water inlet pipe 110 entering the water storage device 130 is higher than 50 degrees in the heating process.

In some embodiments, the first temperature sensor 160 and the second temperature sensor 180 may cooperate to enable the water temperature value in the water storage device 130 to reach the set temperature value and the target temperature value as soon as possible.
