Problems solved by technology

When using a single on-off temperature control, if the upper limit of the temperature is set too high, it is easy to cause damage to the clothes, and if the upper limit of the temperature is set too low, it will seriously affect the temperature rise rate in the drying cylinder. Extended drying time

Embodiment 1

[0048] like figure 2 As shown, this embodiment discloses a method for controlling the temperature of a dry clothes treatment device. The dry clothes treatment device in this embodiment is a clothes dryer, and the dry clothes treatment device is provided with a heating device, a temperature measuring device and a control device electrically connected to each other. The heating device is used to heat the dry clothes treatment device, so as to increase the temperature inside the dry clothes treatment device, accelerate the gasification process of the liquid on the surface of the clothes, and achieve the effect of drying clothes to realize the drying of clothes. At the same time, a temperature measurement device is provided in the dry clothes treatment device, and the temperature measurement device is used to measure the temperature information of the dry clothes treatment device, and send the measured temperature information to the control device; the control device receives the...

Embodiment 2

[0066] like image 3 As shown, this implementation is a supplement to Example 1. The difference between this embodiment and Embodiment 1 is that in this embodiment, when the temperature in the cylinder of the heating device of the drying clothes processing device drops to the lower limit value TTz of the temperature range for the zth time, the drying clothes processing device turns on the heating device. The heating device is used for heating; the lower limit value TTz of the temperature range decreases as the number z of the heating device is switched on. The dry clothes treatment device is provided with a system switch-on temperature TT0, TT0 is a set value, and the value of TTz is infinitely close to TT0 as the number of times z of the heating device is switched on increases. TT0 is determined by the liquid point temperature of the liquid on the clothes in the dry clothes treatment device, and the TT0 is greater than the liquid point temperature.

[0067] The dry clothes tr...

Embodiment 3

[0071] A dry clothes treatment device applying the method for controlling the temperature of a dry clothes treatment device according to any one of the above embodiments is provided with a heating device, a temperature measuring device and a control device electrically connected to each other. The heating device is used to heat the drying clothes processing device to realize the drying of clothes; the temperature measuring device is used to measure the temperature information of the drying clothes processing device, and send the measured temperature information to the control device; The control device receives the temperature information, and controls the heating device to perform an on / off operation within a temperature range according to the temperature information.

[0072] In this embodiment, when the temperature inside the cylinder reaches the upper limit value TDx of the temperature range under the action of the heating device, the drying clothes treatment device disconn...

Abstract

The invention discloses a method for controlling the temperature of a dry clothes treatment device and a dry clothes treatment device. The heating device of the dry clothes treatment device performs an on / off operation within a temperature range. When the upper limit TDx of the temperature range is reached, the heating device is disconnected, and the heating device stops heating; the upper limit TDx of the temperature range decreases as the number x of disconnection of the heating device increases. The present invention adopts a relatively high initial disconnection temperature for the heating device, and quickly raises the temperature in the cylinder to the drying temperature to speed up the preheating time, and multiplies a certain coefficient in the subsequent control parameters for controlling the on-off of the heating device. This coefficient is related to the number of on-off times, realizing the effect that the off-temperature of the dryer gradually decreases with the increase of the number of on-off times, and the on-off temperature is adjusted accordingly with the number of on-off times of the heating device, which effectively balances the dryer. The contradiction between the need for high temperature at the beginning and the need for low temperature later in the drying process.

Description

technical field [0001] The invention belongs to the field of clothes dryer equipment, and in particular relates to a method for controlling the temperature of a clothes drying device and a clothes drying device. Background technique [0002] Clothes dryers are one of the indispensable household appliances in people's daily life. It is a cleaning household appliance that uses electric heating to instantly evaporate and dry the water in the washed clothes. It is especially necessary for the winter in the north and the "returning to the south" in the south where the clothes are difficult to dry. In addition, clothes dryers are widely used in industrial production to dry fabrics and improve production efficiency. [0003] In order to heat the clothes in the dryer at a suitable temperature, a temperature on-off interval is generally set. When the temperature is higher than the highest temperature, the heating device is turned off, and when the temperature is lower than the lowe...
